Owners of private housing construction or summer cottages are often faced with the need to trim the lawn, or mow the rising grass and weeds. Using a regular hand scythe for this purpose is too tedious. A modern mechanized tool called a trimmer will help you bring order to your garden plot. Using a compact and maneuverable mechanical scythe, you can quickly and without wasting energy create a beautiful lawn in front of your house, or get rid of dense thickets of wild grass. Using this tool, you can carefully trim the grass in the most difficult to reach places - under the wall of a house, near trees or between beds in the garden.
Gasoline trimmer device
Numerous models of hand-held lawn mowers available on the market today differ in power (and, as a consequence, in their capabilities), weight, and the presence of certain additional functions that increase ease of use, but the basic design of the tool remains unchanged.
An internal combustion engine is used as a power drive in any gasoline trimmer. By means of a rigid or flexible shaft, the rotation from it is transmitted to the cutting element - a reel with cord (line) or a special knife. The shaft is placed inside a metal rod, at one end of which the engine and fuel tank are fixed, and at the other there is a cutting head.
A handle is attached to the middle part of the rod. Most often, it is on it that the keys, buttons and switches are located, with the help of which the operation of the trimmer is controlled.
The layout of the controls may vary slightly depending on the model of the tool, but, as a rule, this includes a button to turn off the engine, a “gas” button that allows you to control the carburetor throttle, and a stopper for this key when pressed, making it easier to control during large volumes of work.

Trimmer Maintenance - Emptying the Fuel Tank
After use and before servicing your gas trimmer, turn it off and move it to a level surface. Grasp the spark plug cable and remove it from the spark plug. Separate the boot well from the spark plug. If necessary, service the spark plug. Reconnect the cable and install it back on the spark plug.
Turn off the string trimmer and disconnect the spark plug cable.
To be safe, drain your trimmer before servicing it or storing it for a season.
Turn off the string trimmer and disconnect the spark plug cable. Allow the trimmer to cool for at least 15 minutes. Move the trimmer outdoors at a distance of at least 3 m from the work area. Place the metal container on a flat surface.
For safety reasons, drain the fuel from the trimmer.
Unscrew the fuel tank cap and turn it to a horizontal position. Hold the string trimmer motor firmly with both hands and slowly tilt it to the side to pour fuel into the container. Then screw the cap back onto the fuel tank, wipe up any spilled fuel and dispose of it.
Do not reuse spent fuel.
When outdoors, move the trimmer at least 3 m from the drying area. Reconnect the spark plug cable and start the trimmer. Run the string trimmer until the remaining fuel is used up, then turn it off and disconnect the spark plug cable again.
Deciding on the type of gasoline trimmer
All trimmers and lawn mowers available on the market today, depending on their capabilities and purpose, are divided into three classes: household, semi-professional and professional. What tool do you need? This depends primarily on the tasks that will be assigned to him.
Household petrol trimmers
Household trimmers are designed for mowing short grass in a relatively small area, the area of which does not exceed 10-15 acres. As a rule, we are talking about caring for the lawn near the house. They are not capable of more: household trimmers cannot withstand long-term operation, 1-1.5 hours a day is their limit. Thanks to the engine, which is modest in power (no more than 1-1.5 hp) and dimensions, such a tool is lightweight, which means it can be used without special support belts.
Often household trimmers are equipped with a curved rod. The curved shaft of the household trimmer increases its maneuverability and makes it easy to trim grass in hard-to-reach places, such as around bushes. However, due to this design of the rod, a flexible shaft is installed inside, which negatively affects the reliability of the tool. A cord (special fishing line) is usually used as the cutting element of a household trimmer, although some models sometimes include plastic knives as an addition.
Semi-professional, or farm
Semi-professional trimmers are often called farm trimmers, and this fully reflects their purpose. This is a reliable assistant for a rural resident, designed for regular high loads. Such a tool is capable of working for 3-4 hours a day, mowing grass on an area of 20-30 acres. Of course, such a trimmer needs a more powerful engine - 1.5-2.5 hp.
Semi-professional models, unlike household ones, are always equipped with a straight bar and a rigid shaft, which increases their reliability. The cutting part is represented not only by the trimmer head, but also by knives. The latter will help to mow especially tall and thick grass; moreover, they can even cope with weeds and branches of bushes.
Professional, or gardening
A professional trimmer is a powerful tool for urban improvement workers, landscaping companies and public utilities. It is equipped with an engine with a power of over 2.5 hp, has an increased service life and is ready for long hours of daily work. In addition to the trimmer head, such units can be equipped with metal knives that can cope with dense bushes and unnecessary shoots of trees with a trunk thickness of up to 3 cm in diameter.
It’s easy to guess that professional trimmers have a reinforced shaft and a spacious fuel tank. Since such tools are quite massive, they are necessarily equipped with special belts that lighten the load on the operator’s hands, and a professional vibration damping system. It is clear that purchasing a professional trimmer for cutting the lawn next to a private home is simply impractical.
"Lost in Translation"
“A device for cutting grass, held by hand, operated with a fishing line or knife” - what should we call it? The question seems to be elementary: it’s easy to imagine what we’re talking about, but there’s a problem with the terminology. Not only can manufacturing companies call them differently, but translators sometimes choose completely unexpected definitions. It becomes even more fun if the technical documentation was written, say, in Japan, then was translated into some European language, and from it into Russian. Perhaps in this category of small motor equipment you can find the most definitions that mean the same thing. Sometimes they are called "lawn mower", "lawn mower" or "manual lawn mower", some models are called "bush trimmers". This is quite normal within the products of one brand, but other companies use these names to mean completely different equipment.
The other two terms most commonly used are trimmer or brushcutter. One is a tracing paper from English, the second is from Russian. We will use both, but each type of this technique has its own meaning, depending on the location of the engine. It's simple: for a trimmer, the engine is located at the bottom, next to the cutting device; for a brush cutter, it is at the top, and the torque is transmitted through the shaft.
Let us also note that individual features of trimmers and brush cutters, in particular the shape of the handles, are also designated differently by different manufacturers. But more on that a little later.
Gasoline engine type
Gasoline trimmers are equipped with both two-stroke and four-stroke engines. It cannot be said that this or that variety has clear advantages. At least, there is no direct connection between the type of engine and its power - there are both household models with a four-stroke engine, and professional ones with a two-stroke engine.
2 stroke engine
Compared to four-stroke engines, two-stroke engines, being lighter, operate in a higher speed range, which provides greater performance. Of course, two-stroke engines “eat” more fuel and produce a lot of noise and exhaust, but at the same time they impress with their unpretentiousness in operation. Each time you work with a trimmer equipped with a two-stroke engine, you will have to start by preparing a gasoline-oil mixture, but if such an engine suddenly fails, it will most likely not be difficult for you to revive it.
4 stroke engine
Four-stroke engines are free from almost all the disadvantages of two-stroke engines: during operation they produce much less noise, their exhaust gas volume is significantly lower, and gasoline and engine oil are poured into different containers.
They are more economical in terms of fuel consumption and have a longer service life. All this, however, does not mean that four-stroke internal combustion engines are ideal. No, they have their drawbacks.
The design of such an engine is more complex, which means that its maintenance and repair are more difficult. A four-stroke will always be heavier than a two-stroke of equal power, which negatively affects the weight of the entire tool and, consequently, the ease of handling it. And finally, a trimmer equipped with a four-stroke engine will be more expensive than the same one, but with a two-stroke internal combustion engine.
It should be mentioned that, along with classic four-stroke engines, there are also hybrid ones: their operating cycle occurs in 4 strokes, but the lubrication system is the same as that of a regular two-stroke engine.
Popular questions
How to extend the life of your trimmer?
After each mowing, you should wash the tool and clean the head of dirt and dust. The brush cutter should be refueled with high-quality fuel (not lower than 92 grade). When choosing oil, give preference to types used for high-speed equipment.
Does the tank need to be filled to capacity?
Manufacturers do not recommend leaving fuel in the tank after mowing. Therefore, first it is worth assessing the scale of the work and diluting the oil with gasoline in the required quantity. If the fuel is not used up, you can drain it until next time. It is important to note that the mixture retains its properties for 2 weeks.
Engine starting system
The engines of most gasoline trimmers are started manually: by sharply pulling the cable (starter cord), you thereby spin the drum, which in turn drives the engine crankshaft.
Some modern trimmer models are equipped with a Flash Starter easy-start system. By pulling the cable, you cock a special spring in several stages, which, having accumulated energy, transfers it to the crankshaft, which will be the impetus for starting the engine. With the Flash Starter system, the engine starts easier, because the spring gives a higher spin-up speed than can be done by hand. The operator now requires less physical effort, because he no longer needs to make sharp jerks on the cord; the cable can be pulled quite slowly and smoothly.
How to easily start a gas trimmer, watch the video:
To make it easier to start the engine, the power unit of the tool usually has a special button, several presses of which before starting will ensure that the required amount of fuel is supplied to the carburetor.
Electric trimmer Patriot ET 1255 – tool description
This amateur garden tool differs from most of its market analogues in its reduced weight, good traction parameters, and the almost complete absence of vibration and sound impact on the operator.
The well-thought-out and balanced design of the mower makes it possible to use it in conditions of a large number of ornamental plantings, next to benches and pedestrian paths, as well as in other hard-to-reach places,
The manufacturer included a durable electric motor in the proprietary equipment of the scythe. The engine of the tool is distinguished by the simplicity of the device, which makes it easier to maintain and repair it yourself. Each start of a standard factory engine is carried out by simply pressing a button located on the body. To cool the engine, the manufacturer has provided an improved system of constant forced supply of intake air masses.
Features of this Patriot mower include:
- factory engine power – 1.1 kW at 7000 rpm;
- coverage when using cord/knife – 46/23 cm;
- weight – 6.9 kg.
The model is equipped with a collapsible rod that can be folded for more convenient storage or transportation. For comfortable use, the garden tool is equipped with a bicycle handle and a soft shoulder strap.
Tool power
How to choose a gasoline trimmer for cutting grass in your garden? And for cultivating a “plantation” of a couple of hectares? That's right, focusing on its power.
The power of the gasoline engine installed on trimmers can vary from 1 to 3-3.5 hp. The choice of tool for this parameter directly depends on the expected load. It is the power of the trimmer that determines its operational purpose. So, to mow the lawn next to the house, a simple tool with a power of no more than 1.5 liters will be enough. With. Farm trimmers are equipped with a more powerful engine – from 1.5 to 2.5 liters. With. The full range of capabilities of trimmers can only be demonstrated by a professional tool with a power of over 2.5 hp.
It is clear that an increase in the power of a tool inevitably entails an increase in its weight and cost. It follows from this that when choosing, you do not need to mindlessly chase high power indicators, but focus primarily on the planned scope of application of the tool.
Advantages and disadvantages
If we compare the type of garden tool in question with a similar technique for mowing grass, we can highlight both undeniable advantages and some inconveniences.
pros | Minuses |
Ease of storage (especially when disassembled). | The need for careful maintenance before use and long-term storage (lubrication, assembly/disassembly, filling/draining fuel). |
Possibility of choice by power, speed, price. | Noise, vibration and emissions from gasoline trimmers (especially two-stroke). |
Maneuverability. | Limited mowing area (for electric machine). |
Availability of various attachments. | Limited operating time (for battery models). |
Light weight and linear dimensions. | Low power compared to lawn mowers. |
The need to hold the device exactly for tens of minutes to obtain a neat lawn. |
Petrol trimmer rod and shaft
The trimmer rod, inside of which there is a shaft that transmits rotation from the engine to the working head, can be either straight or curved. The first is more reliable, the second is more ergonomic. Straight rods are installed on professional and semi-professional tools. The transmission shaft located inside such a rod is a rigid rod made of especially strong steel. The risk of damage to such a shaft, even under significant loads, is small.
Hard shaft.
Straight rod.
On petrol trimmers with a rigid shaft, the torque from the shaft to the cutting equipment is transmitted through a gearbox with bevel gears. Gearboxes can be serviced or not serviced. The gearbox being serviced has a technological hole through which lubricant can be replaced or added. In unmaintained units, lubricant is provided by the manufacturer for the entire service life.
Some users believe that a maintenance-free gearbox is less durable. In turn, manufacturers note that this step is aimed at increasing the service life of the gearbox, since according to statistics, very often gearboxes fail due to incorrect dosage of lubricant or foreign objects entering during maintenance.
The curved shaft is typical of lightweight residential trimmers. It is more convenient to use a tool with a curved shaft to trim the grass in the immediate vicinity of bushes and trees, benches, fences, etc.
The downside of this convenience is the lower reliability of such tools. The fact is that in this case it is possible to transmit rotation from the engine to the cutting element only through a flexible drive, and the latter is more vulnerable than a rigid shaft, and the likelihood of its failure is much higher.
Flexible shaft.
Curved rod.
The gas trimmer rod can be solid or collapsible. A solid transmission shaft (and this is a guarantee of reliability) can only be installed in a solid rod. But transporting and even simply storing such a tool is less convenient. A collapsible rod, consisting of two or more sections, on the contrary, ensures compactness during transportation and storage.
The disadvantage of detachable rods is obvious: the transmission shaft must also be disconnected, and any drive connection is an additional weak point. In addition, during disassembly, earth, sand and other debris can get inside the rod, which leads to premature wear of the working elements.
How to choose a lawn mower
So, there are quite a lot of varieties of lawn mowers. To choose the right one according to the parameters, you first need to decide on the scope of work. If we are talking about a garden plot, a trimmer or an electric scythe will do; if autonomy is important, a petrol one will do. Cordless models can work in both cases, but they are relatively expensive and still require recharging - they are not designed for large volumes of work away from the outlet. Power for household use is not particularly important, 1 kW for electric or 1 hp. for gasoline ones it is more than enough to work on an area of several hundred square meters. For professional and intensive use, it is better to choose more powerful lawn mowers. If the main task is lawn care, the rule is different: the lighter it is, the more accurately you can process the grass, and here the trimmer has an advantage.
If you plan to work with a knife, you need a scythe with a straight shaft. Most summer residents do not need a knife: the volumes are not the same, and reconfiguration will take too much time. It’s another matter if you use a scythe to cultivate areas with thick weeds and bushes - you can’t do without a knife. Hay for animals is cut only with a knife: cuttings of fishing line in the feed are unacceptable.
And the last thing that needs to be presented is the annual volume of work. A gas mower with a simple engine can have a service life of 50-100 hours; the more complex the engine, the longer the service life of the entire scythe usually is. If the amount of work per year is small (a few hundred square meters of garden or no more than 10 engine hours), there is little point in spending money on the most modern models. If intensive use is expected (and the funds allow), then, of course, it makes sense to take equipment at a higher level.
Battery technology has advanced so far that modern trimmers powered by lithium-ion batteries easily mow even tall and overgrown grass.
Handle type
Filigree control of a rather heavy unit is not as simple as it might seem at first glance. When choosing a trimmer, special attention should be paid to the configuration of the handle, on which the ease of use of the tool directly depends. There are several types of handles:
T-shaped handle , which looks like a bicycle handlebar, allows for wide movements and is convenient for quite long work, so it can often be seen on professional and semi-professional trimmers. All tool controls (starting, speed control, etc.) are located directly on one of the handles, which greatly simplifies work and increases safety.
The J-shaped handle is typical for lightweight household-grade trimmers. With its help, it is easier to control the tool, performing fine maneuvering. All the buttons necessary for the operator are located not on the handle, but on the rod.
D - shaped handle , as well as J-shaped, is installed only on lightweight trimmers intended for home use, since it is designed to hold the tool with one hand.
Before choosing a gasoline lawn mower, the future user must hold it in his hands and evaluate the degree of convenience. It should be borne in mind that any type of handle can be moved along the bar, adjusting the tool to your height and other individual characteristics and thereby achieving maximum ergonomics. Petrol trimmers with D and J-shaped handles are convenient to work in cramped conditions and narrow passages, which are often found in personal plots.
What types of trimmers and brush cutters are there?
The capabilities of a trimmer or brushcutter are determined primarily by the engine installed on it. There are only two options here: electric or gasoline, and there are three varieties: the electric motor can be powered either from the network or from a battery. The “weight category” of the device also depends on the engine power.
The simplest ones are electric trimmers. Since the engine is located at the bottom, its weight cannot be too large: it will be uncomfortable to hold. These are models with power ranging from 300-600 W, line diameter 1.2-1.6 mm. Purpose: Mainly lawn grass care.
Trimmer in edger mode. The support wheel is a huge help in this case.
In weeds, the consumption of fishing line will increase greatly, but if you don’t let it go, you can also mow “soft” young weeds. There are no petrol trimmers - the weight is too much.
Electric brush cutters have more power, and you can use thick fishing line – 2 mm or more in diameter. Many can actually be installed with a disc. The work is simple, there is only one limitation - mow only within a radius of several tens of meters “from the outlet”, and you will also have to control the extension cord. Power is about 1.0-1.3 kW; the electrical network or extension cord may not be able to withstand more.
Cordless trimmers and brush cutters appeared on the market relatively recently, but this area is very promising. Modern nickel-cadmium and lithium-ion batteries can operate on a single charge for several tens of minutes, which is enough to mow areas of several hundred square meters. For a small plot of land - quite enough.
The battery is located on the top of the trimmer, so the motor can be small or quite powerful, like small brush cutters. Usually the engine is placed at the bottom so as not to waste energy on rotating the shaft, but there are also models with a “motor mower” layout. Convenience - independence from the network cable, the disadvantage is still a rather high price. However, their cost is gradually falling, and many manufacturers produce entire lines of garden equipment that can operate from the same battery, so you can save money on its purchase.
Electric models are also interesting because among them (especially trimmers) there are the most diverse design solutions. The products are aimed largely at the “weaker sex”; convenience, lightness and beauty are equally important here.
The choice in the category of brush cutters is even greater, although design issues fade into the background: brush cutters in general are much more similar to each other. With comparable power to electric and light gasoline lawn mowers, their weight is approximately the same, but the upper limit of the power of gasoline models is 34 hp. However, these are not needed in everyday life; these are braids for long-term professional work. The most popular power value for brush cutters is approximately 1 kW for electric and 1 hp. (0.7 kW) for gasoline. In fact, these are scythes of similar power: electric models indicate the consumed power, while gasoline models indicate the output power.
Belt system
Only a good shoulder strap can reduce the load on the hands when working with fairly heavy hand tools, redistributing part of the weight to the operator’s back and shoulders.
Shoulder strap system. For comfortable use of a relatively lightweight household trimmer, a simple one-shoulder belt is enough. If you have to work with a semi-professional or professional-class brush cutter, we strongly recommend that you look for products with two-shoulder belts.
Although backpack-type belt systems
Such backpacks are often equipped with special bags for storing cutting equipment, as well as tools that may be needed to repair the trimmer in the field. And a special pad that manufacturers supply to the belt system protects the operator’s thigh from burns when it comes into contact with an engine that is very hot during operation and reduces the level of transmitted vibration.
What is a gas trimmer?
A walk-behind mower is a hand-held gasoline-powered device that cuts grass using a rapidly rotating (3-9 thousand rpm) cutting tool of various types.
The engine is located at the rear of the machine and is located behind the operator during operation, and the cutting tool is installed on the other side.
The operator independently selects the height and angle of inclination of this tool , which makes it difficult to obtain the same smooth cut surface as obtained after passing by a lawn mower, but he can use a gas trimmer to cut inclined surfaces.
Additional amenities
Availability of anti-vibration system
During operation of the trimmer, vibrations occur, which is generally typical for any mechanism, the individual elements of which perform rapid reciprocating movements. Vibrations can cause the operator to experience noticeable discomfort while working, and frequent use of the tool can cause health problems, the most predictable of which is premature wear of the elbow joints.
A special anti-vibration system will help to significantly reduce the vibration impact on the body of a person working with a trimmer. In the simplest and most common version, it is a set of polymer gaskets located between different structural elements of the trimmer.
Anti-vibration system for lawn mowers.
Such gaskets reduce the transmission of vibration and thereby ensure normal working conditions for the user with the tool. To dampen vibrations, manufacturers often additionally separate the engine from the boom with special shock absorbers. Today, almost all the world's leading brands equip their products with an anti-vibration system.
Fuel tank volume
The capacity of the fuel mixture tank can vary from 0.3 to 1 liter depending on the model. Which trimmer with which gas tank – large or small – should you prefer? Both options have their advantages and disadvantages. A large-capacity tank increases the weight of an already heavy unit, but does not require frequent stops for refueling.
A tank of smaller capacity, in turn, is smaller and heavier, contributing to more economical fuel consumption, but at the same time does not allow long-term non-stop operation. When choosing a trimmer based on such a parameter as the volume of the fuel tank, you should focus on your physical abilities and the size of the area that you will regularly mow. It is very convenient if the fuel container is made of translucent plastic - this allows you to monitor the amount of fuel remaining in it during work.
Device weight
The convenience of working with a trimmer directly depends on its weight, because the entire load falls on the hands and shoulders of the person performing the operation. If the tool turns out to be too heavy for you, then no matter how powerful it is and no matter how well it mows the grass, the end result is unlikely to be satisfactory: you simply will not be able to work with it for a long time and control it delicately when getting to hard-to-reach areas.
That is why, when choosing a trimmer, you should definitely pay attention to the weight of the device, especially if you yourself cannot boast of heroic strength. Don't chase power. In many cases, it is more rational to purchase a less powerful, but at the same time lighter unit: you will spend a little more time mowing your plot, but you will not get so tired that you quit the job without finishing it.
Safety precautions
To ensure that using a trimmer brings only positive emotions, both after mowing and during work, you should follow strict safety recommendations.
- It is better to mow in dry weather.
- The operator's arms and legs must be covered with long sleeves/legs. It is better not to wear open shoes.
- You need to wear special glasses when working: small debris and pieces of grass can injure your eyes.
- In case of loud noise, you should use earplugs.
- It is better to hold the cutting attachment with the casing towards you.
- Do not place your hands or feet near the head of the device when it is turned on!
- It is necessary to monitor the position of the wire: it should be behind the operator.
So, the variety of trimmer models on the market makes it easy to choose the optimal device for any need. Despite the presence of gasoline lawn mowers, the rating of compact mowing devices is headed by electric models. This speaks to consumers' desire to avoid the hassle of refilling their tank. While using a trimmer powered by mains/battery, you need to be careful because of the possibility of a short circuit .
What you need to know about work equipment
The working element of a brush cutter that directly cuts off excess vegetation can be either a cord (special cutting line) or knives. These are consumables, even if they are included in the factory kit of the tool, over time they will have to be purchased and replaced. The choice of equipment used depends on the tasks that you plan to solve with your trimmer, and primarily on the thickness and density of the grass that will be mowed.
Trimmer head
Almost all trimmers are equipped with a trimmer head - a reel designed for winding cutting line. According to the method of feeding the line, all trimmer heads are divided into mechanical (you have to manually pull out the ends of the line yourself), semi-automatic (the line is released when you press a wide button on the bottom plane) or automatic (the protruding ends of the line are lengthened automatically when the engine speed decreases). Semi-automatic cord feeding is considered the most effective; such heads are most popular among users.
In addition, trimmer heads may differ in the maximum permissible diameter of the mowing line that can be threaded into the reel. Household trimmers usually use a line with a diameter of 2 to 2.4 mm, semi-professional trimmers - from 2.4 to 2.7 mm, professional trimmers - from 2.7 to 3 mm.
When choosing a trimmer head, be sure to pay attention to the material from which the lower part is made. It is this part that is the most vulnerable, since it constantly collides with the ground, and it is this part that most often causes the trimmer head to fail.
Knives
To mow particularly thick grass, reeds, bushes, and young trees, they use special knives (cutters) rather than a fishing line. On sale you can find a huge number of varieties of knives for trimmers, differing in material (metal or plastic), shape, and number of cutting blades. By the way, cutters, unlike fishing lines, do not chop up grass, which means they can be used for mowing for harvesting purposes.
Which knife should you choose for your trimmer? When solving this issue, you should first of all focus on the manufacturer’s recommendations, indicating the possibility of using one or another type of equipment on this model. Excessive independence in choosing knives and cutters can lead to trimmer failure.
Components of a trimmer
The design of mowers of various modifications cannot be classified as complex mechanisms. The unit kit includes:
- pen;
- barbell;
- engine;
- head with installed cutting elements;
- gasoline tank;
- belt;
- nozzles
Attachments are used to increase the functionality of the device ; with their use, the trimmer is used for snow removal, cultivation, pruning bushes and young trees.

What is a trimmer and types of hair trimmers.
More and more men are replacing scissors, razors, barbershops and professional hairdressers with home trimmers. And this is understandable - a hair trimmer is relatively inexpensive, it is intended for personal use, therefore, it is safer than its salon counterparts, it is convenient, small-sized, versatile and always at hand.
Many people mistakenly assume that a trimmer is the same hair clipper, only with a modern foreign name. However, the function of the device is not only to trim, but also to trim hair, which can be considered a big advantage of the device. A trimmer is a device for cutting and trimming hair, which is equipped with a kind of scissors and a razor.
Figure 1. Hair trimmers
Before purchasing a device, you need, firstly, to figure out what part of the body it is intended for, and secondly, what characteristics are the priority of the future owner.

Step-by-step instructions on how to mow grass with a lawn mower and save fuel
It is necessary to start the lawn mower mainly on the ground. Some craftsmen know how to wind the instrument while holding it in their hands, but this is quite difficult and dangerous. After launching the tool, you can start using it. First, you should put on protective clothing and an unloading belt. Depending on the model of the tool, the unloading belts may be on carabiners or ties. If a carabiner or latch is used, then after starting the engine, the tool should be secured and started working. If ties are used, then you need to put on the belt together with the working tool.
The first step is to balance the belt. This means that despite the total weight of the tool, the mower’s hands should bear a minimum of load. The mower only moves the tool with his hands, and if balancing is not done, rapid fatigue will occur during work. The entire weight must rest on the worker's shoulders.
When the tool is ready for use, the instructions for cutting grass with a lawn mower are as follows:
- You need to make movements to the right and left slowly, while keeping the trimmer at the same distance from the ground
- The mower's movements should be unhurried (half a step). Experts call the movement of a mower duck steps.
- The biggest difficulty that beginners face is maintaining a stable rpm. The rotation speed should be changed during mowing, depending on the density of the vegetation. If the grass is young, then mowing it does not require working at full capacity.
- The mower must feel the work of the tool. If the scythe cannot cope with the grass, you need to increase the speed. At the same time, it is not recommended to constantly operate the tool at full speed.
- Experts have developed the optimal mode for cutting grass with gas trimmers: in one direction you need to increase the speed above average (almost at full throttle), and when moving the lawn mower back, the gas is released, taking a step forward. This method is relevant for cases when it is necessary to carefully lay the grass in windrows.
Often, disputes arise among lawn mowers about how to mow correctly with a trimmer, whether it is necessary to release the gas or whether it is better to work in constant mode. Let's look at these issues in detail.
- There is an opinion that it is better to mow with a lawn mower in one speed mode. This opinion is not correct. Working with the same power not only increases fuel consumption, but also wears out parts. Relieving gas during reverse movement of the tool is useful, since during this period the engine is cooled, as well as the CPG is lubricated. Relieving gas causes the throttle valve to close, causing fuel to pass through the XX channel, thereby lubricating the parts.
- Relieving the gas allows you not only to mow the grass, but also to carefully place it in windrows. Moving the tool in one direction allows you to mow, and moving it in the opposite direction creates a swath
- The disc only moves in one direction, so it is simply pointless to keep the tool at constant speed when it is moving in the opposite direction
- Relieving the gas causes the cutting disc to rotate the crankshaft by inertia, and coasting is always useful
If you mow with a lawn mower in one speed setting (as beginners usually do), this will affect increased fuel consumption and engine overheating. For comparison, you can imagine the work of a chainsaw. The sawyer gives maximum speed only when necessary, but when the tree is cut down, the chainsaw operates at idle, thereby cooling it.
This is interesting! Petrol mowers are air-cooled, which is achieved through natural airflow, so operating at constant speed increases the likelihood of overheating. The higher the constant speed, the faster the motor will overheat.
Motor- and electric scythe: design features
The trimmer consists of two elements - the motor and the mounting rod. The cutting part of the tool is driven by a transmission shaft connected to the motor shaft. It consists of a rotating head with a fishing line attached to it, less often - a special disk or several knives. The engine can be located either below, in close proximity to the cutting part, or at the top. Models of the second type are equipped with a more powerful but heavier engine. Trimmers with a lower motor are used for trimming even lawns with thin and soft grass .
The bar of a brush cutter can be either detachable or one-piece and is equipped with handles, belts and a stop. The choice of one model or another depends on the individual preferences of the user. As for the dimensions, weight and configuration of the tool, it must be suitable both in height and weight and be “fit to the hand”, that is, as convenient as possible in use.
