✅ How to make a mini tractor from a Neva walk-behind tractor

We will not consider options on an industrial scale, but what can be offered to private summer residents and farmer entrepreneurs is a mini tractor made from a walk-behind tractor. To do this, you just need to purchase a walk-behind tractor, and based on the necessary tasks and capabilities, construct a mini tractor from it. One of the samples for further design can be used a mini tractor from the Neva walk-behind tractor.

How to make a mini tractor from a Neva walk-behind tractor with your own hands, photos and drawings

You don’t always get pleasure from working on a personal plot. Most people try to mechanize this difficult physical work by purchasing walk-behind tractors, cultivators or mini tractors. Some craftsmen, after working with a walk-behind tractor, decide to make a mini tractor from a Neva walk-behind tractor with their own hands. To make the task easier, you can buy a special adapter with a seat, thanks to which the walk-behind tractor will turn into a four-wheeled assistant.

Snow blowers for the Neva walk-behind tractor: types and features

There are such options for snow blowers for the Neva MB 2 walk-behind tractor and other models, such as canopy, blade and brush. The canopy allows you to simulate the operation of a snow blower and remove even stale snow. The blade differs from it in that it allows you to remove a smaller layer of snow over a width of about 1 meter, while the canopy covers approximately 60 cm. The rotary brush is designed for removing freshly fallen snow that has not yet compacted. The only significant drawback of the rotary brush is its heavy weight, so be prepared to reduce the maneuverability of the unit when installing it.

The Neva walk-behind tractor, thanks to its attachments for snow removal, is effective even in winter

DIY snow removal attachments

The disadvantage of all options for winter attachments is the rather high cost of snow blowers for Neva walk-behind tractors. Not everyone can afford to buy such equipment, but this problem can be overcome if you have the necessary skills and tools.

The simplest version of a homemade snow blower for the Neva MB 2 walk-behind tractor and other models is a bulldozer-type blade. To create it, you will need a special adapter that is attached to the unit and a metal sheet with a pointed edge that will act as a snow blade. All parts of the structure are cut out of steel and connected to each other using rods and brackets.

The second, slightly more complex option is a rotary nozzle. It is made from a pipe into which snow is thrown, a box, a gearbox, a shaft and an auger. To make such a nozzle, you will need a welding machine, as well as detailed instructions, which can be found in large quantities on the Internet.

Attachments for snow removal can be made independently or purchased in specialized stores.

The third type of snow removal equipment for the Neva walk-behind tractor is a snow thrower that operates on the principle of a fan. This design is quite complex, so it is recommended to find instructions or a video to create it. Neva walk-behind tractors with a fan attachment are designed to work with soft, not yet compacted snow.

The most complex version of the snow removal attachment that you can make with your own hands is the auger-fan one. It works well on packed and icy snow and can cover a large area, but you will need specialized knowledge and tools to make it.

We make a mini tractor from a Neva walk-behind tractor with our own hands

By making a mini tractor from a Neva walk-behind tractor with your own hands, you will minimize the cost of time and effort, which will result in the appearance of an excellent device for doing all the work on your garden plot. In addition to the adapter, you can purchase: a plow, hiller, harrow and other devices.

You can also upgrade a walk-behind tractor into a mini tractor with your own hands from unused parts of other equipment. This conversion option will take more time, but it will pay off with low costs.

To create a mini tractor from a Neva walk-behind tractor, you will need the following components: the walk-behind tractor itself, metal pipes, corners, sheets; two wheels; welding machine; driver's seat; set of tools.

Step-by-step process for upgrading a walk-behind tractor into a mini tractor

Step 1. We develop the design of the kinematic scheme. The main thing in this scheme is the balance of the structure so that additional loads do not destroy future equipment. This diagram is developed independently, or you can use a ready-made diagram with a kinematic image of a mini tractor.
Step 2. We make a frame from corners and pipes. During the manufacture of the frame, it is important to consider the location of the fork and bushing, which ensure the rotation of the trailer.
Step 3. We make the body. For the body, an excellent material for manufacturing would be steel sheet. The height of the body sides should not exceed 30 cm.
Step 4. Install the driver's seat.
Step 5. Install attachments.
Step 6. We check the performance of the manufactured mini tractor.
Step 7. Painting.

We will consider one of these options for creating a mini tractor using the example of the Neva MB-2s 7.0 PRO walk-behind tractor. This walk-behind tractor is equipped with a Subaru EX 21D engine. If you plow your garden plot with such a walk-behind tractor, then within a week it will be difficult to straighten up. To avoid such consequences, we will convert the walk-behind tractor into a mini tractor.

Since the SUBARU engine does not have a 12V output, the headlights are installed for decoration. To use them you need to install a battery pack or battery. When plowing the land, the imperfections and inconvenience of this technique are not noticed. This mini-tractor was tested on hard-to-plow land. And although during the creation of the tractor its traction characteristics were questioned, the tests were very successful.

Also, a big plus of this machine is that the driver and the front part of the mini tractor are additional weight, which helps the drive wheels to better grip the ground. Installed levers: gas lever - on the right, axle release lever - on the left. To lift the hitch, a sprocket with a diameter of 150 mm is used. It is brought out by a bicycle chain to a lever or a manual jack.

The installed Volga wheels were found in a landfill, pre-cleaned of rust and painted. The pedal arrangement is similar to that of a car: the right pedal is the brake, the left pedal is the clutch. Speeds are switched using a lever. Shoe brakes taken from the Riga-7 moped are installed.

The principle of operation of the clutch pedal is the same as that of a walk-behind tractor: when pressed, the minitractor moves, if you release it, it stops. There is a cable connected to the left armrest lever that unlocks the axles. It is used when turning is necessary. There are no special nuances when turning right or left. The right armrest houses the throttle lever. The hitch lift lever is located under the seat.

The wear on the drive belt on the gearbox is the same as on a walk-behind tractor. The sum of the weight of the driver and the front part of the tractor is 100-110 kg, which keeps the front of the mini tractor from lifting when the plow is deepened. The size of the processed track remains the same as the walk-behind tractor - 630 mm. Stability problems arise if plowing goes deeper than 20 cm.

How to make a mini tractor from a Neva walk-behind tractor

In the field of agriculture, there are numerous tasks that need to be completed according to routine and compliance with agronomic standards.
And if we take into account that this is the twenty-first century, and life has accelerated to the limit of possibility, then the question arises: how to optimally manage the work on cultivating land plots in time and without additional material costs. We will not consider options on an industrial scale, but what can be offered to private summer residents and farmer entrepreneurs is a mini tractor made from a walk-behind tractor. To do this, you just need to purchase a walk-behind tractor, and based on the necessary tasks and capabilities, construct a mini tractor from it. One of the samples for further design can be used a mini tractor from the Neva walk-behind tractor.

Neva walk-behind tractors with 7.5 hp Subaru engine: reviews from owners and features of the units

Subaru engines with a power of 7.5 horsepower are installed on Neva MB 2 walk-behind tractors. The price of such a device is slightly higher than that of the standard MB-2 model, but the performance characteristics are also higher. The model is equipped with a four-stroke Japanese engine, which allows it to perform a wide range of work, as well as use the unit as a vehicle or transportation vehicle. The engine of the Neva Subaru 7.5 hp walk-behind tractor maintains stable speed at any air temperature, which makes it equally effective for use in winter and summer.

Neva 7.5 hp walk-behind tractors with a Subaru engine can be used for cutting grass, digging up potatoes, removing debris from the site, loosening the soil and many other purposes. Reviews from owners speak of the high power and maneuverability of the device, as well as ease of operation and management. And if you need to expand the functionality of the unit using attachments, then this can easily be done on your own.

Helpful advice! When using a Neva walk-behind tractor with a 7.5 hp Subaru engine, make sure that the weight of additional equipment does not outweigh the unit itself. If this does happen, use weights.

Subaru 7.5 hp engine is efficient to use at any time of the year

Advantages of a homemade design

First of all, this is the cost of the final product (provided that inexpensive components are used, and if you do it yourself)
Such a vehicle runs on several liters of fuel and can reach speeds of more than 20 km/h.
It does not take up much space, which is vital in small farming with the capabilities of summer residents.
The ability to assemble such a unit practically from scrap materials.

Before assembling a mini tractor from a walk-behind tractor based on the Neva unit, it will be very useful to study similar drawings of the main components, design concepts, calculate costs and possible devices for connecting both main and auxiliary devices. It should also be taken into account that the essence of the tractor’s operation lies in its mass, which is the main factor in adhesion to the ground, that is, the device must weigh more than 200 kg.

Manufacturing of additional accessories

Walk-behind tractors go on sale assembled and with minimal equipment. A plow and a cutter are clearly not enough to perform the entire volume of agricultural work. A factory kit for converting a walk-behind tractor can cost more than the unit itself. You can make various attachments and trailers from scrap materials, using tools that are in every pantry of a country house or cottage.

Drawing of cutters for a walk-behind tractor Drawing of a plow for a walk-behind tractor Drawing of a trolley for a walk-behind tractor

It is worth considering some options for making additional equipment yourself:

A converted rake for collecting grass clippings, debris, branches and fallen leaves. If you do this work manually, it will take a lot of time and effort. Trailed equipment will allow you to clean large areas within a few minutes. To work, you will need a wide strip of sheet iron and several meters of reinforcement with a cross section of 8-12 mm. The reinforcement must be cut into pieces 10 cm long and welded to the plate in several rows and at intervals of 3-4 cm. Long rods are welded to the plate for attaching to the walk-behind tractor frame. Trailed rakes can be equipped with rollers to improve maneuverability and smoothness.
Snow plow. Most units operate much more efficiently in the cold because they do not overheat. You can mechanize snow removal in winter. The blade is made from two pieces of channel welded together. This allows you to get a gripping height of up to 40 cm. The width of the blade is selected according to the power and weight of the unit within 40-80 cm. The blade is attached rigidly to the front of the machine with bolts. Initially, it can be mobile or stationary.
Trolley and trailer. The walk-behind tractor cannot be driven on the road, so it does not have to be adjusted to the requirements of the traffic rules. The cart is made from a corner, a channel and old wheels from a small car, and a trailer is attached to it. It is made from metal profiles and boards. The towing clutch is made standard, like for cars or tractors.

By showing a creative approach, you can make a hiller, harrows and potato digger that are not inferior in quality to their factory counterparts.

Requirements for a homemade walk-behind tractor

Power, taking into account the possible processing area
What type of fuel will you use, and, accordingly, your priorities in speed or economy.
It is worth considering the cost of the walk-behind tractor, since world-famous and well-known brands will cost an order of magnitude more. And therefore it is better to give preference to a domestic manufacturer.

Among the affordable and optimal quality walk-behind tractors, we can mention the following walk-behind tractors: AGRO, Neva, MTZ, Centaur, Zubr.

The listed models have a number of advantages and they should be chosen based on subjective needs and tasks.

Engine and hydraulic installation

The most profitable option for converting a walk-behind tractor into a homemade four-wheeled tractor is considered to be a single-cylinder water-cooled diesel engine - this is usually installed on Chinese motor-cultivators of the SCOUT, Zubr and Russian Neva brands. A single-cylinder diesel engine is economical, so operating a mini-tractor based on it will not be expensive. It is typically placed on the front of the frame, allowing the small tractor to maintain optimal balance when operating with additional tools. A fastening system is installed at the location of the motor, which is best made “floating” (sliding) to simplify the adjustment and tension of the belts.

The transmission of force from the engine to the rear wheels of a homemade tractor is organized using a belt drive. The PTO transfer case, like the gearbox, can be used from a decommissioned GAZ-53 car. The homemade power unit is mounted in such a way that the PTO pulley is located in the same plane as the pulley located on the rear axle of the mini-tractor. At the same time, they mark out a place for the clutch pedal. The belt drive is covered with a protective cover to avoid slipping during operation and to make its service life longer. After completing the main work, a hydraulic lift is installed on a homemade mini-tractor with an engine from a walk-behind tractor. The hydraulic conversion kit must include an oil pump, oil reservoir, hydraulic cylinder and distributor. All components of the system are connected by flexible oil-resistant hoses. It is advisable to make the hydraulics in a floating mode - this will ensure full operation of the motor-tractor hitch. Then the rotary cutter will work as it should.

Then the driver's seat is installed.

Materials and tools

To assemble a mini tractor based on a walk-behind tractor, you will need, in addition to the Neva itself:

electric welding machine;
grinding machine (for rolling and fitting);
drill;
a set of necessary simple tools;
winch, jack system;

From the materials required for construction:

Dashboard;
A pair of wheels suitable in size and strength;
Hub brake system;
Steering rod;
Steering rods;
Transmission;
Angles, pipes or profiles;
Canopy system;

Blueprints

First of all, when moving on to studying the drawings, you need to decide for what functions the mini-tractor will be used: what will be more included in its tasks - agricultural work or transportation of goods. The final design depends on this. Note that many users prefer universal designs that allow both working with agricultural attachments and transporting heavy loads in a trailer. Therefore, universal drawings are most often suitable.

By the way, if you don’t have a trailer on your farm, you can also assemble it yourself if you wish, since the design is not much different from a mini-tractor.
And since the selection of materials that will become components will be made in any case, you can make both a mini-tractor and a trailer at the same time. It is only important that all the selected parts fit together well. This is interesting: a homemade mini tractor from an MTZ walk-behind tractor.
To ensure proper operation of the device and high reliability, it is recommended to first draw a diagram of the future tractor. It should display the connection points between the axle and the gear shaft. It also makes sense to provide rear-wheel drive to increase the cross-country ability and maneuverability of the mini-tractor. And it is imperative to consider the design of the rotating device. Once its design has been selected, you can proceed to assembly.

Assembly steps

You need to start assembly from the base, and this, of course, is the frame. It is necessary to have pre-measured and cut pieces of metal strictly according to the level. To ensure rigid fastening and eliminate any backlash, they are fastened together using a welding machine. You can use regular bolts, but this type of fastening is more difficult to implement and requires more calculations.

By purchasing ready-made hubs, which also include brakes, you will save yourself a lot of time and effort on making mistakes. And attaching them is not difficult: hubs are attached to a pipe of sufficient strength and cut to size at the ends.

The pipe is attached to the frame through drilled holes, then the steering rods and brakes are attached. And at the end the steering column is installed.

For the rear axle, pressed bearings are installed into bushings on the prepared pipe. The axle, to obtain torque, is connected through a pulley to the motor. The wheels, depending on the power of the device, can be used on a small car. If the power is low and the area to be processed is small, then you can use separately sold wheels with an internal chamber of small diameter.

The ergonomics of the driver’s workplace is also of great importance. The seat and control complex in it, as well as being on the transport itself, should be as comfortable as possible. This means there is a need to design:

seats;
seat cushioning;
steering wheel location;
simplicity and accessibility of control levers.

To make working on a walk-behind tractor as comfortable as possible and avoid additional stressful hypothetical moments, the device can be modified at your own individual discretion, and this is:

Protective shields or a full-fledged cabin for protection from the external environment;
the ability to disassemble components in the field;
universality of fastenings to simplify the search for spare parts and modifications;
steering rod calculation;
low center of gravity.

Of course, a self-made minitractor based on a walk-behind tractor will be inferior to factory-made copies in terms of reliability and optimality of design, but in terms of cost, the owner of such a project can independently vary the cost of components, as well as adjust it to exclusively subjective, and possibly non-standard needs.

With the proper skill, patience and diligence, almost every farmer, as well as a simple amateur, will be able to build such a thing, having, of course, invested the necessary amount of money in the material and the block itself.

Homemade mini tractors

Ideal for processing small areas. Almost anyone who understands technology, even at a minimal level, can assemble them.

How to make a mini tractor from a Neva walk-behind tractor

First, we purchase the walk-behind tractor itself, on which a hitch is already pre-mounted, either factory-made or home-made. Then it will be possible to attach trailers with a body, which can easily transport cargo, regardless of size. There are other additional details that add comfort during use:

Brake and gas pedals.
Seat.
Steering Wheel.

The volume of Neva walk-behind tractors is usually in the range of 6-8 liters. Therefore, a mini-tractor with such a base requires a minimum number of modifications.

If you have electric welding and a grinder along with additional tools, you can create a dump truck on your own. The main thing is to give a special design to the frame mount, and make sure that the mini tractor from the walk-behind tractor can tilt the trailer and turn it. The controls for these devices duplicate each other, so the walk-behind tractor can be used separately by simply disassembling the small tractor.

Homemade mini tractor from the Zubr walk-behind tractor

Of the required details:

Frame.
Cylinder with brake.
Footrests, pedals.
Steering column, complete with rods.
The beam is in front, connected to the hubs and discs for the brakes.
Wings at the back.
Rear linkage with manual lift.

The last step is the joint assembly, using a hammer and drill, wrenches with a welding machine. Additionally, wheels are installed in front. The engine is attached to the frame at the front, so the minitractor maintains balance during operation. The power take-off shaft is located on the same axis with the pulley on the rear axle of the vehicle. Belt drive helps transmit power from one part to another. Belt tension and adjustment will be easier if the motor mount is floating.

Mini tractor based on MTZ walk-behind tractor

This walk-behind tractor has one difference from other standard models - it is equipped with a two-cylinder diesel engine. This causes the center to be heavier in the front when the device is actively operating. Because of this, the work process becomes noticeably more complicated. But you can fix the problem by doing the following:

We use the mode of operation with mowers.
The platform in front is completely dismantled.
It is replaced by a wheel from the front of the motorcycle, for which we use bolts. At the same time, the steering wheel is installed.
At the top of the frame there is a niche where the steering rod is installed. The adjusting rod must also be secured here, then the structure will receive an increase in strength and hardness.
We use electric welding to connect the platform and the mount for the driver’s seat.
The engine must have an additional platform where the hydraulic distributor with the battery is placed.
The rear part is connected to an additional metal frame for the hydraulic system.
The front motorcycle seat is ideal for handbrake placement.

Let's get a compact mini-tractor with three wheels.

Mini tractor made from Agro walk-behind tractor

As always, we prepare several basic parts in advance - the steering and braking system, additional wheels, and the hydraulic system. Hydraulics are needed for the system to work properly in conjunction with attachments. Extra wheels are easy to take from a regular car.

In the case of the Agro walk-behind tractor, additional steps will be needed to strengthen the drive axle shaft along with the wheel gearboxes. Let's assume that the engine of the device is located behind. Then the load will be distributed as evenly as possible.

Do-it-yourself mini tractor with a Centaur walk-behind tractor

Centaur walk-behind tractors are a type of professional equipment designed for agricultural work. Therefore, in the end, the mini-tractor will have high productivity.

The key component is the engine, with a power of up to 9 horsepower. It is necessary to use a metal profile to make a frame for this design. We install the seat along with the wheelset. Additional equipment in the form of a trailer is acceptable, which helps transport small-sized cargo. Other useful additions include single-share plows and moldboards.

Minitractor from the Neva walk-behind tractor. Overview of options

If a farmer has a walk-behind tractor, gardening work is much easier. However, walk-behind tractors have one drawback and that is that you have to walk behind them. And when it is necessary to carry out work on large areas, the legs are subjected to very great physical stress. To facilitate this process, many craftsmen are converting their walk-behind tractors into mini tractors.

Almost all Neva walk-behind tractors have sufficient power to be converted into a mini tractor. Many people believe that this is a labor-intensive process that requires practical skills, but this is not entirely true. On the Internet there are a large number of different drawings and diagrams for making a mini tractor from a Neva walk-behind tractor. These drawings have already been assembled by someone else, and their plausibility and correct dimensions have been confirmed by someone else's experience.

This is approximately what a mini tractor assembled from a walk-behind tractor looks like and its operation:

Gasoline and diesel walk-behind tractors Neva: features, types and advantages

Under the Mototekhnika Neva trademark, a large number of walk-behind tractors are produced, differing in their performance characteristics. You can choose a model that will ideally suit your requirements. Let's look at popular models of walk-behind tractors.

Neva walk-behind tractors can significantly facilitate work on the ground

MB-Compact - used for processing small areas, characterized by compact dimensions and ease of operation. The MB-Compact engine power is 6.5 hp, and the design of the model allows you to install various attachments on it. The model operates on 2 forward and one reverse gears, which can be switched by simply turning the lever. The support wheel is not included in the basic kit, but you can easily install it yourself.

MB-1 - differs from the previous model in the increased number of gears, there are 3 of them. The unit is designed to work with medium-heavy soils and can be used as a vehicle, as well as for removing snow, leaves and various types of dirt. The engine power for the Neva MB-1 walk-behind tractor is 6.5 hp.

MB-2 – equipped with an engine from the Japanese company Honda with a power of 5.8 hp. The advantage of the Neva walk-behind tractor with a Honda engine is that the number of gears, which is three in the base model, can be doubled by simply rearranging the belt in the engine. You can also install various types of attachments for the Neva MB 2 walk-behind tractor, which will allow you to use it as harvesting equipment. Compared to other models, MB-2 wheels are characterized by an increased diameter, which increases cross-country ability.

The Neva MB-2 walk-behind tractor has high cross-country ability, so it is convenient to use in large areas

MB-23 is the most powerful model in the line, equipped with a 10 hp engine, which makes it an excellent choice for long and difficult work, including plowing unplowed soil. In addition, the model is highly maneuverable thanks to the wheel release function. This walk-behind tractor model can be converted into a vehicle, as well as attached to a trailer and used as a tractor.

MB-23SD – equipped with a 4.8 hp diesel engine from Subaru. It is characterized by a low arable speed, thanks to which it can effectively cultivate even frozen soil. Just like in other models, the Neva walk-behind tractor with a Subaru engine can be equipped with attachments.

Regardless of the model, all Neva walk-behind tractors are characterized by the following advantages:

imported engines with high efficiency, allowing for efficient cultivation of the soil;
the ability to install a variety of attachments and attachments to the Neva walk-behind tractor, significantly expanding its functionality;
ease of operation and maintenance. To work with a walk-behind tractor, you do not need any special skills; you just need to read the instructions;
a simple gear shift system, thanks to which you can set the optimal speed for certain types of work.

Motoblocks of the Neva series are widely used for planting potatoes

Helpful advice! When choosing a walk-behind tractor model, consider the density of the soil you will be working with, as well as the season. Based on these parameters, it is necessary to select engine power and other characteristics.

Which walk-behind tractor is suitable for conversion?

Here you should clearly determine the power that will be needed. After all, it’s not enough to just make a mini tractor. The engine must be capable of driving not only attachments, but also the weight of the walk-behind tractor itself with its frame and a person.

The Neva MB-23S 9.0 PRO model is best suited. It has a 4-stroke engine. And 9 horsepower is enough to generate traction force, which is sufficient to drive plows, cultivators, hillers, etc.

If the power is not enough, then the simplest solution is to simply buy an adapter. Convenience is certainly not at the same level, but you can move around while sitting. And that's a plus.

But the downside is that the use of some attachments is not compatible with it.

But it is compatible with a mini tractor:

Choosing a walk-behind tractor

Almost any walk-behind tractor can be successfully converted into a mini-tractor.
However, it is important to understand that failure of the original device to meet certain criteria will not allow the resulting unit to effectively and efficiently cope with its tasks. For example, if the engine power is low, it may not have enough draft force to withstand not only the standard load when working with attachments, but also additional load - in the form of additional structures and body weight of the operator that were not initially taken into account

Therefore, when choosing a unit for conversion, it is important to take into account its characteristics:

the power must correspond to the area of the site and the planned loads on the unit;
type of fuel - it is best to be guided by the criterion of practicality, so diesel fuel will be optimal for a mini-tractor, due to its economical consumption over large areas;
the massiveness must be sufficient for the device to cope well with hard soil. Unlike a walk-behind tractor, the lightness of which determines its maneuverability, in this case the low weight will be a disadvantage;
cost is an important criterion, given that one of the goals of refurbishment is precisely to save money. Therefore, if you are choosing a new walk-behind tractor for conversion, it is better to choose an inexpensive domestic model with a high-quality and powerful engine.

Among small Russian-made agricultural units, brands such as Argo, Neva, Centaur, MT3, and Zubr are especially well suited for turning from a walk-behind tractor into a mini-tractor. Most models from these manufacturers meet all of the above criteria. Based on the demand for them and reviews from owners, it can be judged that these devices have proven themselves to be reliable and economical equipment, easy to use and easy to repair, thanks to the availability of spare parts. Below we will look at, as an example, a mini-tractor converted from an Agros walk-behind tractor.

Necessary consumables, parts and spare parts

To understand what is needed for manufacturing, let's look at the main elements of a finished mini tractor:

Frame (made from any rolled metal)
Device for making turns
Any brakes
Seat
Metal for body trim
A coupling that is used to connect other equipment.

All these components can be purchased at car dismantling sites or scrap yards. But their choice should be approached responsibly. Often they are not completely new, so they need to be carefully inspected for integrity and defects. After all, the use of damaged components cannot be allowed here. Otherwise, the entire device will not work correctly.

Headlight and dimensions for walk-behind tractor

Almost all owners of land plots have to decide how to make light on a walk-behind tractor. Very often you have to work late or drive modernized equipment in the dark. Without path lighting, it is not only inconvenient, but also dangerous.

There are the following options for installing headlights and dimensions for the Neva walk-behind tractor:

From the generator. A standard product or a generator from a passenger car is used. To prevent the light from dimming when the speed decreases, it is better to take a generator from a tractor. The part is installed on a bracket welded to the frame.
From the battery. If the unit is heavy, it is better to use a battery from a moped or outboard motor. It is advisable to install batteries from passenger cars on light walk-behind tractors. They will not only provide a long-lasting glow, but will also press the wheels to the ground.

To expand the lighting sector, the headlight itself must be installed on a bracket. It is better to place the power switch on the steering wheel. The wires must be insulated and placed in a corrugated tube.

What do they say on the forums?

There is an active discussion on the forums about the pros and cons of a mini tractor made from a walk-behind tractor. How best to build, what materials are best to choose, where to get them, etc.

Here are some comments from them.

“I have had a walk-behind tractor for a long time. I wanted to buy an adapter for it so that I wouldn’t have to walk around all the time. But I came across an idea with a mini tractor. At first it seemed impossible to do it yourself. However, after not delving much into it, I realized that there is nothing heavy here. And I can do this on my own. I chose a drawing and bought all the components at a local scrap metal collection point. And in a month of leisurely work I assembled it. Now the neighbors are jealous. And those who say that you can buy an adapter and be happy, admit that your hands are simply not capable of making a mini tractor from a walk-behind tractor yourself.”

Vyacheslav says:

“I had a walk-behind tractor. I worked with him for about a couple of years and could not be happier with him. But I want to constantly improve and learn something new. And so I wondered, why do I constantly go after him, are there any alternatives? And I found it. The solution was to build a mini tractor. The design is as simple as 5 kopecks. I had everything I needed. Therefore, in just a couple of days I assembled my model using a ready-made scheme that I chose on the forums. I use it and enjoy it"

Basic faults

Belt adjustment and dimensions

For the Neva MB-2 walk-behind tractor, the A-1180 drive belt is used. This model uses one belt that provides forward movement.

In other modifications of the Neva MB-2 model, two drive belts are used. Reverse gearing occurs in the gearbox itself.

Replacing the belt for MB-2 walk-behind tractors is carried out in the following sequence:

The shield is removed, and then the pulley protective cover.
The spring from the walk-behind tractor rod is removed to loosen the belt.
The screws securing the bracket are turned.
The bracket rotates to a position in which the limiting pins do not prevent the part from being removed from the pulley.
The pulleys are adjusted, and then a new belt is installed.
Pull the belt onto the gear shaft pulley, and then onto the motor pulley.
In reverse order, place the remaining parts in their places.

Replacement of gearbox seals

The oil seals in the Neva MB-2 walk-behind tractor are replaced if an oil leak is detected.

This condition is dangerous because the walk-behind tractor gearbox may be left without oil, and this will lead to rapid wear of the unit.

The sequence for replacing oil seals is as follows:

Remove the cutters from the shaft, cleaning the shaft and covers from dirt and oil residues.
Unscrew the cover bolts, tap off the oil and debris, and remove the cover from the gearbox.
The old oil seal is replaced with a new one and wiped dry.
The cover is returned to its place (if necessary, it is placed on sealant) and fixed with bolts.

Adjusting and tuning the Neva MB-2 carburetor

Neva MB-2 device
The functionality and durability of the walk-behind tractor engine depends on the stable operation of the carburetor. This is why its adjustment and tuning are so important. In addition, if the carburetor is incorrectly configured, a gasoline walk-behind tractor may experience increased fuel consumption

The carburetor of the Neva MB-2 walk-behind tractor is adjusted as follows:

The full throttle and idle screw are turned to the limit.
Both screws are unscrewed 1-1.5 turns.
Next comes starting and warming up the engine.
The throttle control lever is placed in a position in which the engine will operate at minimum speed.
Set the minimum idle speed until the unit operates stable.
The idle speed is set to maximum.
The minimum idle speed is adjusted.
Steps 6 and 7 are performed until the engine runs smoothly (more smoothly by ear) at idle speed.

For long-term and uninterrupted operation of the walk-behind tractor, it is necessary to regularly perform engine diagnostics, monitor the frequency of oil changes, and also comply with operating conditions and time intervals for scheduled maintenance.

Adjustment of valves

Adjusting the valves is a fairly simple procedure that requires wrenches, screwdrivers and a feeler gauge. The valve adjustment process is needed to establish optimal and technically correct clearances between the valves of a walk-behind tractor engine. Adjusting valves using the example of the Neva MB-23 walk-behind tractor (the principle is the same for everyone)

The adjustment sequence is as follows:

remove the casing that covers the engine;
remove the valve box cover;
make adjustments (see below);
Reinstall the valve box cover;
Replace the casing.

The valves are located under the valve cover. The gap size can be checked with a feeler gauge. The intake valve clearance is 0.15 mm, and the exhaust valve clearance is 0.2 mm. The dipstick should fit under the valve with the correct gap size.

To adjust, the valve nuts are loosened, then a feeler gauge is inserted, after which the adjustment itself is made, and the valve nut is tightened.

The manufacturer emphasizes that in Neva MB-2 walk-behind tractors, the gaps between the ends of the valves and the ends of the pushers (0.1÷0.2 mm) are ensured by grinding the ends during the initial assembly of the engine and are not adjusted during operation!

Checking and adjusting the clutch of the Neva MB-2 walk-behind tractor

The main function of the clutch is to connect the gearbox to the engine, disengage it, and also connect other operating devices to the engine. If an overload occurs during operation, the clutch begins to slip - this is how other parts of the walk-behind tractor are protected from damage.

Checking the clutch operation can be done according to the diagram below.

If the clutch lever is in the disengaged position, the clutch cable is loose. Consequently, the tension roller lowers and comes into contact with the drive belt. After which the drive belt and small roller move to the lowered position - this stops the supply of power from the engine to the transmission.

When the clutch lever is moved to the "ON" position, the clutch cable pulls the idler pulley, therefore the bottom of the belt is pressed tightly, the small pulley moves the large pulley and power is transferred.

Adjusting or adjusting the clutch of the Neva MB-2 walk-behind tractor is performed as follows:

if the clutch lever is engaged, it will lift the tension roller, setting the walk-behind tractor in motion. The correct position is for the V-belts to be parallel on either side of the engine pulley.
If the clutch lever is loose, the tension roller will drop and disengage the clutch. To avoid disabling the clutch, and therefore slipping the walk-behind tractor, you need to monitor the position of the V-belts, bringing them to a parallel position.

Basic rules for setting the ignition

Checking and setting the ignition on the Neva MB-2 walk-behind tractor is carried out according to the following principle:

the spark plug is turned out, the electrodes are wiped dry, then the carbon deposits are removed;
the gap between the electrodes is measured and set;
the spark plug body is fixed on the cylinder head;
the crankshaft is scrolled up to 4 times (a starter cord is used for scrolling);
If the ignition is working properly, a white-blue spark should be struck. Its absence or yellow color indicates a malfunction.

Next, you should check the condition of the flywheel and stator and the size of the gap between them (the norm is from 0.10 to 0.15 mm).

The gap is increased, if necessary, using a feeler gauge. As an auxiliary tool in the absence of a probe, you can use an A4 sheet folded in four or a razor blade. If the gap between the flywheel and the stator is normal, the ignition will work properly.

Malfunctions with spark plugs

Different conditions of spark plugs
First of all, check the functionality of the spark plug.

To do this, you need to unscrew the spark plug, wipe the electrodes and remove carbon deposits. Then follow the steps described above in adjusting the ignition. The spark plugs are OK if there is a spark. If there is no spark, the spark plug will probably need to be replaced.

In the operating instructions for the Neva MB-2 walk-behind tractor, the manufacturer indicates the size of the gaps between the electrodes of the spark plugs and the recommended models of spark plugs:

spark plug A11P (made in Russia) - gap 0.5÷0.6 mm. Wrench dimensions 20.8 mm;
spark plug NR17С (BRISK) - gap 0.5÷0.6 mm. Wrench dimensions 20.8 mm;
spark plug WR8AC (BOSСH) - gap 0.5÷0.6 mm. Wrench dimensions 20.8 mm.

Before starting to operate the walk-behind tractor, it is necessary to check whether the sealing washer is installed on the spark plug and whether the sealing washer from the previous spark plug remains in the hole of the cylinder head.

The spark plug can be removed and installed only after the cylinder head has completely cooled down to ambient temperature. If, when removing the spark plug from the engine, the tightening torque was exceeded by more than 50%, further use of such a plug is NOT PERMITTED.

Motoblock Neva MB-2 does not start, shoots, smokes - the main causes of problems and their elimination

In fact, the walk-behind tractor may not start for many reasons. Here are the main ones:

the wires are oxidized (cleaning and/or replacement is necessary);
the insulation of the wires is broken (restore/replace the wire);
the carburetor or gas hose is clogged (cleaning and purging is necessary);
watering of the oil has occurred (the oil must be drained and replaced);
there is no spark (replacing the spark plug will help);
uneven surface on which they are trying to start the walk-behind tractor (install it clearly horizontally so that fuel flows);
Magneto failure (replacement will help).

If the walk-behind tractor smokes, the reason may be the following:

One of the most common reasons for smoke coming out of a walk-behind tractor may be low-quality fuel, for example, bad gasoline. Smoke can also come from the strong angle of the walk-behind tractor. Another cause of smoke is oil getting on the valve; Burning oil produces thick smoke that will not go away until it is completely burned.

The walk-behind tractor makes shooting sounds and popping sounds. The probable cause of such sounds:

low fuel level (add fuel to the gas tank);
debris getting under the needle valve (it is necessary to completely eliminate the debris);
clogged jets (cleaning helps);
air filter clogged (blowing helps);
misalignment of the float axis, low fuel level in the float chamber (adding fuel to the tank will help).

Minitractor from a Neva walk-behind tractor

When you have your own summer cottage, sooner or later you will think about mechanizing it. That is, some routine work will be performed by different equipment, which will only need to be controlled. And one of the universal assistants is a walk-behind tractor. However, its purchase will not solve many dilemmas regarding the cultivation of land. But from a walk-behind tractor you can build a more advanced and efficient machine - a mini tractor.

Today, the Neva walk-behind tractor is very often used to create it. This is a high-quality Russian walk-behind tractor with good characteristics and prices.

Power plant tuning

Its power and equipment performance depend on the stability of the engine. Upgrading a standard engine is very expensive and unpromising. But, there are several ways to make the engine more efficient.

Install a quality spark plug. Regularly clean it from carbon deposits and periodically check the clearance. At the first sign of loss of power, replace the spark plug.
Use the best gaskets on all connections. This allows you to maintain the required pressure in the unit, preventing a decrease in power and the formation of smoke during operation.
Fill the engine with the best oil to the upper mark. It should be remembered that when the unit is tilted, oil flows away from the rubbing parts.
Check the quality of fuel before filling the tank. It is advisable to let it sit for a while so that the water sinks to the bottom of the container. The tank itself must be cleaned and wiped dry every 2-3 days.
Install an additional radiator. To do this, steel plates are welded to the engine housing, which will effectively remove excess heat.

A radical solution is to replace the power plant with a more powerful and advanced one. Today you can purchase Japanese, Chinese and European engines, which are characterized by high performance and reliability. It is possible that the frame will have to be redesigned to accommodate the new power plant.

Making a mini tractor from a Neva walk-behind tractor

By creating a mini tractor from a Neva walk-behind tractor with your own efforts, you will receive the following amenities:

This technique does not require a large space for its placement. This means there is no need to build a garage for it.
The price is significantly lower than the price of a ready-made working adapter for a walk-behind tractor.
Operation requires the cheapest fuel and in small volumes. 2 liters will be enough.
Maximum speed – 30 km/h.
It is not difficult to get spare parts for it. They are available almost everywhere and their prices are quite low.
If you equip such a vehicle with tires with deep tread, you can achieve high cross-country ability and excellent traction.
Thanks to its compact size, you can also work in difficult areas where trees grow abundantly. It also allows for comfortable work in the local area. In this case, neither asphalt nor paving slabs are affected.

Of course, creating such a masterpiece yourself is possible if you have certain skills and knowledge. Before the main work, you will need to analyze many different drawings and diagrams, read technical literature and watch useful videos.

External tuning of the unit

Structurally, light, medium and heavy walk-behind tractors are practically the same. They consist of a power plant, chassis and controls. The operator resembles an ancient plowman, holding the handles of the machine with both hands. However, it is not protected from sunlight, rain, snow and heat coming from the engine. To create additional comfort, you do not need to spend additional money. Everything you need is at hand. External modernization of a walk-behind tractor involves the installation of a removable or permanent awning, an additional protective casing or hood over the power plant.

roulette;
building level;
Bulgarian;
welding machine;
electric drill;
set of wrenches;
steel or aluminum corner 30 x 30 mm;
paint brush;
acrylic paint;
tarpaulin or cellular polycarbonate;
flexible plastic.

External modification of the walk-behind tractor is carried out in the following sequence:

Drawing up drawings. It is necessary to accurately calculate all dimensions of the frame and provide options for attaching it to the frame and handles.
Carrying out markings, cutting out blanks for the awning, casing, wings and hood.
Welding a frame from a corner. Drilling mounting holes, cleaning metal from rust, oil and dirt. Painting of the manufactured structure.
Fitting the frame onto the frame. Marking and making holes in it. Fastening the frame with bolts and nuts, checking the reliability of all connections.
Installation of plastic casings and awnings on frames.

There is an option to mount the instrument panel on the handle. This way the unit will look solid and representative. The operator additionally gets the opportunity to control the state of the power plant, know the speed of the machine and the distance traveled. When remodeling the walk-behind tractor from the outside, you need to pay attention to ensuring that air freely penetrates to the motor, cooling it efficiently.

Selection of walk-behind tractor

When choosing a walk-behind tractor in the Neva line for a future miniature tractor, you need to take into account the following parameters: power, weight, engine type, plow parameters, price aspects.

Power . It is determined by the area of the zone where the work will be carried out. The larger it is, the more powerful the walk-behind tractor should be. The best option here is the Neva MB-23. Today it is the leader in power among all representatives of this line. Can also work on very hard soils. Creates a traction force of 180 kgf. Can unlock one of the wheels. Improves maneuverability. Engines of various powers can be installed in it. Today there is a very wide range of them. Thanks to this, each master will be able to choose the appropriate option.

Usually Neva MB-23 is presented in the following variations: 10.0 and 8.0.

Data of the first: Briggs&Stratton engine, its power is 10 l, the number of gears is 4 (2), the role of transmission is performed by a gear reducer filled with oil, suitable gasoline AI-92 and AI-95, processing parameter 86 - 127 cm, milling speed from 20 to 160 (per minute), carries out processing at a level of 20 cm. Second data: the engine is the same, only with the parameter 8 l, all other indicators are identical. Today you need to pay from 43,000 to 45,000 rubles for the Neva MB-23. The modification you purchase matters.

If you need a more modest unit, you can purchase the Neva MB-2. This is also a very productive technique, but with a less powerful engine. It has many modifications, for example “6.5 Pro” and “7.5 Pro”.

They are powered by the same brand of engine. In one modification its power is 6.5 liters, in the second - 7.5 liters. Their similar characteristics: a chain reducer as a transmission, suitable gasoline AI 95 and 92, processing level 20 cm, its width - 86-127, milling speed from 20 to 160 (per minute), weight - 98 kg, number of gears 4 (2 ). Distinctive indicators: – functional volume, in the 6.5 model it is 205 cc, in the 7.5 version it reaches 215 cc, – fuel tank, its volume in the first model is 3.8 liters, in the second – 4.6 . Today the price of Neva MB-2 is in the range of 33,000 - 45,000 rubles. Weight. The following rule applies here: the more complex the excavation work, the higher the weight of the walk-behind tractor, and the reverse principle. When choosing between a gasoline or diesel engine, base it on the factors that are more important to you. If you need a quiet device that starts quickly in cold weather, then give preference to the gasoline type. If you need a more economical device with stronger traction and stable speed, purchase the diesel version. This version also works better with difficult soils and large areas. Plow parameter. It depends on the depth of the upcoming processing. It is better to take a collapsible modification in which you can adjust the width. This way you can configure the plow for a given situation

Choosing a walk-behind tractor

Important parameters for these devices are worth listing:

Cost, manufacturer.
Plow size.
Type of engine used.
Weight.
Power level.

A detailed consideration is relevant for each characteristic.

Power. Usually it depends on the area that requires processing in a particular area. The larger the area, the more powerful the walk-behind tractor you need to take.

The weight is determined by the type of soil being cultivated. For hard soil types, you should not choose too light devices. Otherwise, mini tractors simply will not cope with their purpose.

Compared to gasoline engines, diesel engines are much quieter. They have low compression, allowing them to start even in severe frosts without additional problems. But diesel wins in terms of efficiency of its use. It has stable revs and increased traction. A diesel engine will cope better with heavy soils and large areas.

Readiness for physical loads, depth and patience are factors that must be taken into account when determining the appropriate dimensions for a future purchase. The optimal choice is considered to be collapsible models that are adjustable in width, then the plow can be easily adjusted depending on your needs at a particular moment.

There is a close relationship between factors such as cost and manufacturer. If possible, it is better to choose products from companies that have been on the market for a long time. But you can get by with cheaper analogues if financial possibilities are limited. Russian products will also be the best option for the majority.

Chinese walk-behind tractors

Basically these are copies of Russian models. Their cost is lower, but it is achieved not only due to cheap labor, but also savings on materials for production and technological equipment. This negatively affects the quality of finished products.

At the same time, the functionality does not differ from Russian analogues. Buyers have also long had the opinion that goods from China are disposable. The production of walk-behind tractors was no exception. Recently, products of acceptable quality have appeared in this direction, but they are still far from even their analogues from Russia. Chinese technology is intended mainly for those who have plumbing skills and a supply of almost professional-level tools.

Russian products

The optimal solution with an affordable price. Options with a V-belt drive or transmission of torque to a mower, snow blower or broom have become popular among buyers. In any case, the process cannot be completed without the participation of a special belt.

A special feature of our developments is the simple design of the clutch system. This makes operation and repair easier. The only maintenance procedure left is belt replacement. Soviet engineers also designed a gearbox that is recognized as one of the most successful on the market. Professional imported engines are used. The units are functional and reliable. They are slightly inferior to imported ones, but in terms of cost they are far ahead.

Step-by-step instructions for creating a mini tractor yourself.

The redesign of the Neva walk-behind tractor begins with the kinematic diagram of the intended equipment. Here you can make do with your knowledge (if you have it), contact specialists, or find the required drawing on the Internet.

Questions regarding the configuration of a minitractor come down to the manufacture of the frame and body, seat and steering wheel, arrangement of wheels and tires, and installation of levers.

Frame and body

The frame is created from metal pipes and corners. Fastening of components is based on bolted connections. Drill and welding equipment are involved in the work here. The weight of the frame and its strength should be in an optimal ratio. If desired or necessary, you can add a body to the package. This way you will protect various components from contamination. In addition, such a tractor will look more solid, and the driver will receive protection from dirt. The body is usually made of stainless steel.

Seat and steering

You can use the seat of an old car. Its main criterion is convenience. After attaching the chair, the steering wheel is installed and its tilt and height are adjusted. The principle of steering technology from go-karts is often used. In this case, the rods are made of shorter length and greater strength. The steering wheel can also be taken from an old car.

Wheels and tires

They are also usually taken from old cars. But there is an important nuance here - the front wheels of the minitractor must have diameters of 12-14. If this parameter is less, the equipment will go “nose” into the ground. If it is greater than the specified values, problems will arise with controlling this equipment. Take tires that match the dimensions of the installed wheels.

Installation of levers

The levers should make control obedient and comfortable. Their responsibility: clutch and brake. The best option for their device is a cable drive. It is in contact with the motor block. After assembly, the equipment is painted and attachments are installed. Then comes the run-in. It allows you to test all components and components. At this stage, all potential problems can be eliminated in a timely manner. If no incidents occurred during the break-in, you can attach the trailer and run in again. After these operations, if you have the desire and financial potential, you can “pump up” your mini tractor. Here it is possible to install a canopy, headlights, hydraulics, etc.

As a result, you will create high-quality and comfortable equipment that will significantly simplify household work on your suburban area.

And when for some reason you want to sell this unit, you can make good money and offset the costs of it. Today, the prices of such used tractors are determined solely by their owners. It is important to base it on the cost of the walk-behind tractor and other key components, as well as the degree of wear and tear of the equipment. If your mini tractor is in excellent condition and is sophisticated, you can put it up for sale for at least 80,000 -90,000 rubles.

Making a tractor

If you attach additional chassis to the walk-behind tractor, it will turn into a full-fledged self-propelled machine. All-wheel drive is done using a regular motorcycle chain and two sprockets welded to the axle shafts.

If you decide to upgrade the Neva walk-behind tractor, do-it-yourself modifications are carried out in the following sequence:

Project development. It is necessary to carefully calculate the weight distribution on the front and rear axles. In this case, the load must be adequate to the capabilities of the machine.
Making the frame. For this purpose, reinforced steel corners are used. If you plan to transport a heavy load, then it is advisable to strengthen the bottom of the trailer with a channel.
Body assembly. The classic solution is to use sheet metal. However, multi-layer plywood or board can be a budget alternative to metal. At any time, wood can be replaced with steel.
Making a seat for the driver. If it is factory made, then it needs to be welded to the frame. Homemade is welded from pipes or corners.
Cleaning metal from rust and scale. After this, the frame must be immediately treated with an anti-corrosion compound and painted. You can install one of the devices on the drawbar for cultivating the soil, planting tubers or cleaning the area.
Equipping the built trailer with brakes. This is necessary to prevent it from tipping over when there is a sudden change in the speed of the walk-behind tractor.

To create additional pressure on the drive wheels, they need to be weighted. For this purpose, special overlays on the hubs or canopies on the frame are used. Control of a tractor based on a walk-behind tractor can be improved by replacing the control rods with a full-fledged steering column. For such a modification, you can use an old part from a VAZ 2121, on which the gear shift knob is already placed on the column.
