How to install a coil on a trimmer

Equipment for mowing weeds and lawns with proper care can last for more than one year, but consumables for the device will have to be purchased and replaced regularly. Replenishing supplies of lubricant, fuel (for lawn mowers), fishing line (cord, strings), knives and discs is not enough. You will need to take care of the main cutting tool - the trimmer reel. This part may break due to long work or be of low quality from the start. Therefore, it is better to find out in advance how to find a replacement for it and not make a mistake with the choice. A description of all types of reels and the most significant criteria when choosing, as well as the top five models in different categories, is in the material below.

How to thread the line into the trimmer?

Any device for mowing vegetation is necessarily equipped with a reel, which, in turn, may differ in different models with a thread feed system (automatic, semi-automatic and manual). It is this parameter that you should start from before deciding how to thread the fishing line into the trimmer.

In order to thread the line into the trimmer , you need to take at least 5 meters of material, which is then folded in half. The center of the cutting element must be inserted into a specially designated place, and then, using visual cues on the reel indicating the direction, the cutting device should be wound. At the end of all the work, the lid, of course, will need to be screwed on.

Types of reels according to their correspondence with lawn mowers

In addition to the methods of charging and feeding the cutting cord, mowing sets are divided among themselves according to their compliance with different models of trimmers. The following reels are available for sale:

original – suitable only for certain models of brush cutters. It will not be possible to use them for installation with other trimmers due to mismatched threaded connections;

universal – these models can be installed on any lawn mower. A universal reel costs a little more, but it can be used alternately by several owners of different lawn mowers.

Most often you can find original coils from the brands Stihl, Husqvarna, Oleo-Mac, and Echo on sale. In turn, universal mowing sets are produced by Champion, Shindaiwa, and Partner.

What is a trimmer?

The basis of this equipment is the following elements:

a motor whose main function is to rotate the cutting head at the end of the rod;
directly the head, consisting of a reel on which either fishing line or a knife can be wound;
knives or fishing line rotating at high speed, which are the main cutting part of the device; how to load fishing line into a trimmer will be discussed a little further.

An electric device is inferior in power to a gasoline device, so it is ideal for working on a standard plot of land adjacent to a house with a source of electrical energy. The main positive aspects of such equipment are the absence of noise during operation, light weight, ease of operation and, of course, environmental friendliness.

As for gasoline trimmers, such equipment, of course, is more mobile, so you can safely transport it from place to place and get rid of annoying vegetation in any area. There is no need to use electricity here, which has a positive effect on the functionality of such a device - the cutting attachments can be changed when working with a wide variety of weeds.

One of the most common attachments is fishing line, so we should take a closer look at this element.

Types of fishing line for trimmers

As a rule, the division of the fishing line is based on the different diameter of the samples, which can vary from 1.2 to 4 mm. The most commonly used material is with a thickness of 2 mm, but in no case should we forget that the choice should depend primarily on the trimmer model.

There is one main rule here: the more power the device has, the thicker the fishing line should be.

This element can also differ in the type of its section. So, it can have a round (suitable for cutting simple grass) or square (for mowing soft green cover) shape, sharp edges (tall grass) or be equipped with notches, ideal for grass with a thin diameter.

Do not forget that using a fishing line you can only mow grass, but for other, coarser vegetation, you must use knives.

Next, you should consider in more detail the process of how to insert the fishing line into the trimmer correctly. After all, it is with this procedure that many consumers often have difficulties.

Line adjustment

One of the main rules when replacing and adjusting equipment is that any manipulations with the mechanism must be carried out exclusively with the engine turned off and the device plug disconnected from the mains.

Perhaps these tips will tell you how to thread the line into the trimmer as correctly as possible and, accordingly, give your area a neat and aesthetic appearance. All that is required is to correctly select the cutting material required by type and, of course, decide on the category of the trimmer used.

Winding fishing line onto the trimmer

Measured and careful removal of the spool from the braid reel makes it possible to proceed directly to winding the fishing line. The design features of the head, the number and location of the fixing holes dictate the sequence of actions when performing this operation, and also determine the methods used. Today there are several types of reels, depending on the number of tendrils of the fishing line and the methods for threading it:

Trimmer head with one working tendril;
A reel with two tendrils of fishing line;
Reel with automatic winding.

After the coil is removed from the head, it must be carefully disassembled. It is better to do this on an already mowed area, because there may be a spring inside the coil, which will be quite difficult to find in the tallest grass. Electrical circuit of a trimmer with half an electric trimmer. As you are convinced. After disassembly, we will have three parts on our hands: the body (top cover), the protective casing and the coil .

Classification by filling method

The trimmer head can have several ways to thread the line:

Fast chargers. The new cord is wound without disassembling the reel, that is, there is no need to remove it from the device. The end of the new element is inserted into the reel and then wound a certain number of times. When a specific value is reached, the cord is cut. The head with line for this type of trimmer is produced by Shindaiwa and Speed-Freed.
Collapsible. Here the name itself speaks for itself. To replace a new cord, you need to remove the reel from the equipment, then unwind the old line and wind on a new one.

One end of the fishing line is inserted into the fixing technological hole located inside the spool.
The fishing line is wound onto the drum in the opposite direction to the rotation of the spool on the trimmer product - as a rule, on the inside of the reel an arrow indicates which direction the winding is going.
A small section of the fishing line is left free to be brought out - it is fixed in a specialized groove on the inside of the bobbin, designed to hold the winding when assembling the spool into working condition.
The remaining end of the line is passed through the hole in the outer part of the reel.
The reel halves are assembled and put on the trimmer rod.

How to wind line on a trimmer reel: key points

A gasoline or electric trimmer is an indispensable assistant in the arsenal of a modern summer resident or owner of his own home.

Thanks to these garden devices, you can easily mow even a large garden plot. After purchasing this tool and doing several mowings, many people think about how to properly wind the fishing line onto the trimmer reel. For an inexperienced user, the first operation to replace it will seem problematic and time-consuming, since developers often do not fully reflect the instructions for replacing fishing line in the instruction manual.

What types of spinning reels are there?

3 types of reels that are known to spinning anglers today have become widespread. These are coils such as:

Smooth and easy reel movement

Such properties have a severe impact on the final fishing experience, because it allows you to simply and accurately control the bait and moderately lay the line on the spool. Incorrect laying makes problems during fishing, because the line may become tangled during casting, and this will not allow you to cast the bait far and accurately, which is important.

The spool mechanism should not create extraneous noise during operation, because it is transmitted along the fishing line to the bait and can make the fish think. The smoothness of the spool is also of fundamental importance, so it is imperative to check it by running your finger along its side. If there are even the smallest nicks, it is better not to take such a reel.

Multiplier

Such reels are also called sea reels, as they are designed for catching large fish. These are quite massive reels with a long casting range and line reeling speed. In the near future, experienced spinners began to install them on spinning rods more and more often. How true this is is up to them to decide. But this type of reel also requires experience and is not suitable for beginners. When you master wiring techniques, you don’t necessarily need to have a cool, expensive reel.

Preparing for replacement

For clarity, the mowing head (spool) was removed from the brush cutter. There is no need to remove the fishing line to replace it; everything is done locally. It doesn't take much time.

How to replace the ignition on a trimmer?

Now you need to figure out which way you need to wind it. To do this, many manufacturers of trimmers put special markings on the reels, such as in the figure below.

If no such markings were found, then you need to pay attention to the spool body. There must be an arrow there that indicates the movement of the mowing head. The line is wound in the opposite direction.

Types of semi-automatic heads

A semi-automatic mowing head usually consists of a housing, inside of which there are several springs and a spool. Spools, according to their design, are divided into:

single-section – in devices of this type, the cutting line used is wound evenly;

two-section – in these spools, each end of the cord must be wound separately, onto the part intended for this. Two-section spools differ from single-section spools in durability and ease of operation. In addition, the fishing line inside them never bends or gets tangled.

Many owners of household trimmers convert single-section spools to two-section ones. To do this, you will need to find a durable metal plate and apply a contour with the diameter of the spool on it. After this, the plate is cut along the contour so that the thickness is near the place where the cord is wound. As a result, the resulting circle should move freely around its axis. Next, you will need to make a cut on the resulting ring and insert the spool inside the ring. Both parts must be connected to each other using tape or quick-drying glue. As a result, the manufacturer will have a spool in which the line can be wound into two sections.

How to properly install a reel on a trimmer

How to wind line on a trimmer reel

Product spools may have different thread feeding systems. It can be manual, semi-automatic or automatic feed. Depending on this, it is necessary to wind the fishing line. So how do you thread the spool? To begin, unscrew the cap on the reel (see video). If the thread on it is left-handed, then you need to turn it clockwise, and not as is usually done.

Such a thread is made so that the trimmer head cannot unwind during operation of the product. To thread the thread you will need about 5 meters of material (see photo). It needs to be folded strictly in half, the center inserted into a specially designated place on the device and wound in the direction of the arrow, which should be drawn on the reel, as in the video. After this, you just need to screw on the cap.

A country toilet is a mandatory attribute of a garden plot. Even if they are not going to build a summer home, it will take the whole day.

Country cottages of residents of megalopolises resemble garden houses less and less; they are already quite modern “dachas” - places for relaxation and hobbies.

Types of fishing line

Trimmer thread can be divided into types according to its diameter. It can start as small as 1.2 millimeters and reach up to 4 millimeters. The most commonly used is the diameter of 2 millimeters. But it must be selected strictly individually, based on the specific model of the device. Often the required diameter of the product is indicated in the product passport. Typically, the more powerful the trimmer, the larger the line diameter should be. For example, it is best to wind a thread with a diameter of 2.4 millimeters on the reel of a lawn mower, and for a product with a weak engine, a thread diameter of 1.6 millimeters is suitable.

The fishing lines also differ in the type of section. It can be round (for mowing regular grass), square (for soft and often mowed grass), with sharp edges (for tall grass), with notches (for thin grass), and also complex (see photo). The latter cannot be filled into all types of devices. It should be noted that the fishing line is intended exclusively for mowing grass. To cope with other types of plants, you need to use a brush cutter with a sharp knife. The length of threads that can be threaded into a trimmer can range from 10 to 100 meters.

Automatic spools for trimmers, how often do they break?

These are modern coils that have high reliability and efficiency. The principle of their operation is such that the cord is lengthened when the engine speed is reduced in automatic mode. The mower does not need to control the process of feeding the line, as this happens automatically.

Automatic heads are 2-3 times more expensive than semi-automatic ones, so not every trimmer owner can afford such devices. However, experience confirms that a good and high-quality automatic reel for a trimmer or lawn mower lasts quite a long time and does not break. The advantages of automatic heads also include the high speed of line threading. To do this, the fishing line is threaded through the holes in the head, and it is wound manually onto the reel.

The test shown in the video below will help you verify the effectiveness of automatic trimmer reels. Heads of different types are used as experimental “rabbits”.

Step-by-step instructions on how to wind fishing line onto a trimmer reel

With the arrival of spring, you often spend your time at the dacha or in your garden. A trimmer will protect you from problems such as grass and weeds . This tool easily trims and mows grass in difficult areas where a conventional lawn mower cannot do it. Trimmer. A very effective and convenient tool for mowing grass along fences, flower beds, houses and rows in the garden. Several types of garden trimmers have been invented (gasoline, electric and battery). It would seem that everything is fine, you have such a wonderful assistant in your arsenal, but over time the cutting element wears out and it becomes necessary to replace the exhausted fishing line. But not everyone knows how to thread fishing line into a trimmer. We suggest using step-by-step instructions with attached photographs.

Instructions on how to wind fishing line onto a trimmer reel

1. First you need to disassemble the trimmer head. Press the latch on the product body and turn the cover clockwise. We remove the bobbin.
Now we have to figure out how to wind the fishing line onto the trimmer reel. We measure out approximately 6-7m of fishing line and insert its end into the bobbin hole.
We wind the fishing line on both sides. The winding direction is always indicated on the bobbin in the form of an arrow.
Leave the ends of the cutting element 15 cm long free. Do not wind too much fishing line. Leave 6mm between the outer edge of the bobbin and the line.
We insert the remaining two ends of the fishing line into the opposite holes of the bobbin.
We fix both ends into the grooves on the head body.
Carefully install the spring back into the bobbin guides and into the head body.
In order for the line to be threaded into the trimmer correctly, it is necessary that the bobbin goes back into the head body (press it lightly). If necessary, pull the free ends of the line out. One by one, sharply pull the ends of the cutting element so that they come out of the grooves of the bobbin and pass freely through the holes in the head.
So, we figured out how to wind the fishing line onto the trimmer reel. All that remains is to align all the grooves on the head body and close the cover. Then press the bobbin and begin to rotate it counterclockwise until it stops. While holding the bobbin, turn it slightly clockwise and release it. If there is a clicking sound, it means it has latched into the head. If this does not happen, then you need to repeat the action again.
Pull the free ends of the line out as far as they will go.

Purpose and device

The trimmer reel (spool) holds the line for cutting the grass. On some devices the cord is wound in turns, on others ready-made sections are attached . In the first case, the length of the fishing line is 1-8 m, and in some models up to 15 m, in the second - several tens of centimeters for each fragment. The coil itself is the central part of the trimmer's working head, but the terms are often used interchangeably.

The spool with the fishing line wound on it is enclosed in a housing that includes two parts: a base and a cover, which are connected using latches. The cord is threaded through holes in the body, of which there can be 2 or more, for example, to use fishing line of different diameters without changing the reel. Between the bobbin and the cap is a spring that allows the line to come out or be pulled out to replace the frayed end. The structure is screwed to the trimmer rod with a bolt.

On a note! In spider-type reels, the cord sections are attached individually, as in the universal model T 31 of the Kumm brand, or in a bundle in the very center, as in the aluminum head T 34 of the same manufacturer or in the similar model Hopper wth905a.

We wind the fishing line onto the trimmer reel

Owners who have their own garden plots are often faced with the problem of lawn maintenance, namely the need for high-quality grass mowing. For these purposes, either a manual or an electric-powered scythe is used - a trimmer (see photo). It is clear that working with an electric model is much easier and faster. The grass is cut using a line rotating at high speeds. But during operation, the thread wears out over time and requires replacement. So how do you wind fishing line onto a trimmer reel with your own hands?

Required materials and tools

trimmer attachment can be purchased on Aliexpress. But you can avoid overpaying and make the same, or maybe even better, part with your own hands. This homemade reel for a lawn mower is suitable not only for fishing line, but also for cable. This is very convenient and profitable, since the fishing line is difficult to cope with thick plant stems and is used up faster.

The homemade product is based on the tape drive mechanism of a reel-to-reel tape recorder. Many people have old tape recorders at home, so there shouldn’t be any problems finding spare parts. You will also need a protective cover from the car pillar, which will act as a cover, a metal washer and a hex nut with a left-hand thread.

For work you will need the following tools and materials:

drilling machine or hammer drill;
set of drills;
electric drill;
drill or chisel;
cable or fishing line.

Additionally, you will need a ruler, wire cutters, a wrench and some other auxiliary tools.

DIY indestructible coil for trimmer

The trimmer has a carefully thought out reliable design. But like any invention, the trimmer tends to break down and fail. A particularly common problem with this device is damage to the plastic fishing line spool. During operation, pebbles bounce off the trimmer, which can hit the reel and break it. The coil also burst for other reasons. The solution to this problem is quite simple - purchase and install a new coil. But since manufacturers make parts only from plastic, they constantly break. And if you’re tired of constantly buying parts for your lawn mower, you can make an indestructible reel with your own hands. This is done easily and simply.

How to make it yourself

After all the materials and tools have been prepared, you can proceed directly to the process of creating an indestructible coil:

Drill an 11.5 hole in the middle of the tape mechanism.
Eliminate unnecessary castings that interfere with the normal connection of parts. This can be done using a chisel or drill. A drill will remove the metal elements faster, but this should be done carefully to avoid injury.

Then drill holes around the circumference of the mechanism for the cable or fishing line. The diameter of the holes depends on the thickness of the cable. If it reaches 2mm, then the hole should be 3mm. The number of holes is determined individually, usually 4-6 pieces are enough. The holes should be at an equal distance from each other, so you will need to make markings using a ruler.

How to quickly wind fishing line onto the mowing head of a trimmer or brush cutter

In order for the cable to fray less at the entrance and exit, simply make a lug. Take a drill with a slightly larger diameter (for example, 6) and work through each hole for 2 seconds.

Remove the top of the circle on the mechanism so that there is approximately 5 mm from the bottom to the top. You can focus on the edge. This can be done on the grinder.

Now all that remains is to cut the required length of the cable. Take approximately 70 cm and bite off 3 pieces of cable of this length. Tie a knot approximately in the middle of the cable and thread it through the hole. Repeat this with all the segments.

At the end, all that remains is to assemble the finished structure. Install the mechanism with cables on the trimmer , put a new head and washer on top and secure everything with a nut.

That's all, all that remains is to test the resulting homemade product on the grass. This design is very efficient and reliable. It is much stronger and more durable than a factory plastic reel . Therefore, if you often use a lawn mower and want it to last as long as possible, take just 15-20 minutes of time, find the necessary elements and make such an indestructible reel.

So, the failure of the trimmer head is an unpleasant, but easily removable obstacle on the way to a tidy area or harvested hay. Even if the model you need is not in the store, you can always make a reel with your own hands, although with the current variety of garden products you have to resort to this method very rarely.

Trimmer coil structure

Mowing heads for trimmers come in a variety of designs, some simple and some complex. The figure below shows a semi-automatic trimmer head from a Husqvarna brush cutter (Husqvarna) disassembled.

This type of head is present in most gas mowers and electric trimmers, such as STIHL (STIHL), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The design of the mowing head is quite simple. It includes the following parts:

mowing head base;

button for semi-automatic cord feeding;

a spool ( reel ) into which the fishing line is threaded;

spring;

eyes - through them the fishing line comes out;

trimmer head cover;

fishing line (cord).

There are also simpler trimmer heads, shown in the following photo.

READ Trimmer what is the gap on the coil

All these attachments do not allow you to change the length of the fishing line in semi-automatic mode (after pressing a button). If the cord breaks, you have to stop the mower and change it manually.

Criterias of choice

Before purchasing a spool, you should refer to the documentation for the trimmer, which indicates the recommended parameters of the mowing heads, line thickness, diameter of the mounting hole for the spool, type of fastening, thread (left or right) and fixation axes (rigid or rotating 90/180/360 degrees ) . The same information is indicated on the packaging of consumables along with the models of equipment on which a specific head can be installed.

Of the three types of reels based on the line feeding method, it is better to choose semi-automatic ones. They are more convenient than manual ones. Among these spools there are quick-loading models, as well as universal samples designed for different trimmers and with holes for fishing line of various thicknesses. With this head you can mow two or three types of grass: soft lawn, wild grass and tall grass with tough stems. For each type of thicket, you will only need to buy a cord of a suitable cross-section, and not a separate reel.
If you only have to mow a certain type of vegetation, you can choose a reel for fishing line of the same diameter. Other tasks can be handled with knives or discs.
Cutting heads made from brittle plastic that are too cheap break quickly, so saving too much can result in new costs.
You should not install coils of little-known brands on trimmers from famous manufacturers. Popular companies produce components that are best suited for equipment of the same brand.

Often, market leaders produce reels for trimmers from other companies. In this case, the replacement will work no worse than the original. For example, the Denzel 96304 working head is suitable for gasoline and electric trimmers of the same brand, but is also recommended for use on Greenline and MTD mowers.

On a note! Some reels are designed to work only with trimmers from one manufacturer, although the range can be quite wide. Thus, the T25 head for the Husqvarna 128R gasoline machine will fit three dozen models of lawn mowers from the same company.

Among the best manufacturers it is worth highlighting the German companies Al-ko, Bosch, Stihl, Gardena, the Swedish Husqvarna, the American Black & Decker, Patriot, the Japanese Ryobi, Makita, the Russian Champion, Denzel, Huter, Khoper, and the Ukrainian Foresta.

How to remove the reel and replace the line

Owners of trimmers, mostly beginners, become confused, bordering on panic, when the need arises to change the cutting tool or line in the reel. Very often, when trying to unscrew the mowing head, users simply render it unusable, not suspecting that it is unscrewing in the opposite direction. To prevent this from happening, if you need to replace the tool, it is recommended that you read the step-by-step instructions below.

Before threading the line into the spool, turn off the engine of the brush cutter or turn off the power to the electric trimmer to avoid injury that could occur if the cutting tool is accidentally started to rotate.
Unscrew the attachment attached to the gearbox shaft. To do this, the shaft must be fixed by aligning the holes on the washer and on the axle, and inserting a metal rod or screwdriver into them.
Unscrew the nozzle. You should know that the thread on the shaft is left-handed. Therefore, you should turn the trimmer coil to the right, that is, clockwise.
Disassemble the mowing head. Most often, the head cover is secured with clips. To remove it, you will need to push these clips into the body, pressing the edges of the cover. If your trimmer is equipped with a semi-automatic mowing head that has a button on the bottom, then disassembling the attachment must be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
Cut the required amount of fishing line. Typically its length is 5 meters. Use cord of the same diameter as specified in the instructions for the tool. It is not recommended to exceed the maximum diameter of the fishing line, as this will result in increased load on the engine and higher gas consumption.
Find the middle of the length of cord by folding it in half. You will end up with a loop.
Special grooves are cut inside the coil (there may be holes). Insert a loop of fishing line into this groove.
Wind the line onto the reel by turning it counterclockwise. The cord should be threaded as evenly as possible, the turns should lie without overlap and with good tension. When the winding is completed, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the reel.
Assemble the mowing head. Before finally assembling the nozzle, do not forget to insert the spring and washer (if available). Place the reel in the housing and thread the ends of the cord through the holes or eyes.
Put on the cover and secure it with the latches.
Screw the attachment back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counterclockwise).

Line does not automatically extend

If, when you lightly hit the trimmer coil button on the ground, the line does not lengthen, then the reasons for this may be the following.

Option 1 - biting occurred, i.e. clamping the cord between the turns. This problem usually appears if the user winds the line onto the reel unevenly, with intersecting turns, or winds it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, resulting in possible inter-turn clamping of the fishing line. To fix the problem, you will have to disassemble the reel on a trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2 - the ends are too short and protrude from the head. The line may not come out when it hits the ground if its ends protruding from the head are not long enough (short). In this case, the centrifugal force is not enough to stretch the line. Therefore, you need to stop the unit (turn off the engine or unplug the electric trimmer) and pull out the line manually, after pressing the button.

Option 3 - the fishing line is soldered inside the mowing head. This causes the reel to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the reel during prolonged operation of the unit, impact of the fishing line on hard objects.

In the first case, the cord from third-party manufacturers may be made of low-quality and fusible materials that cannot withstand mechanical and temperature loads. Therefore, preference should be given to “branded” fishing lines.
But, if you nevertheless purchased a fishing line of unknown quality, and it often gets soldered during operation, then you can follow the example of some users who, after threading the cord into the reel, moisten it with either silicone grease (from a can) or mineral oil. This procedure greatly reduces the likelihood of soldering turns of fishing line together.
Also, the fishing line can become soldered if, during mowing, it hits a hard object (stone, fence, dry branch, etc.). As a result of this, it stretches a little and is pulled back into the head at high speed. The cord heats up due to friction, and its turns stick together. The only thing that can be done to eliminate this problem is to open the trimmer reel and rewind the line.

DIY trimmer coil repair

A trimmer , whether gasoline or electric, is the only correct solution for cutting grass in hard-to-reach places that a wheeled lawn mower cannot handle. Trimmers use metal knives or a special fishing line as a cutting tool, which is threaded into the trimmer reel. But, unfortunately, trimmer heads become unusable over time during use. Some problems can be fixed with your own hands, while others will require a complete replacement of the mowing head.

The cord spontaneously elongates

There are situations when a trimmer user notices a very rapid consumption of fishing line. At the same time, he never hit the button on the ground to lengthen the fishing line. The reason that the line spontaneously lengthens, being cut off by a special knife on the casing of the device, may be the absence of a spring in the mowing head. Often, novice users of mowers, trying to load fishing line into the reel, forget to install the pressure spring in the head, or completely lose it when opening the lid, and in the future, do not even suspect its existence.

Also, the line can be extended without using a button if the spring is weakened. If checking the spring has confirmed this fact, then it is necessary to place several washers under it to strengthen its clamping properties.

Basic coil malfunctions

Users of electric trimmers and lawn mowers often encounter problems with the semi-automatic mowing head. Coil malfunctions can be the following:

the line does not extend automatically;
the cord spontaneously comes out of the reel.

3rd place – Bosch K-103. This is a universal reel weighing approximately 300 g. In most cases, it is used to complete brush cutters by Makita and Hyundai. The model stands out for its low cutting cord consumption, impact resistance and durability. The core and other parts are made of forged steel, and the body is made of plastic;

2nd place – Flymo 15. This automatic model for trimmers is equipped with a narrow cup, which leads to increased consumption of cutting line. Still, it performed well when cutting grass in rocky areas. To work with it, you need to use only a narrow fishing line;

1st place – EFCO 8100. This model is one of the most reliable mowing heads. It operates in 100% automatic mode, which simplifies its filling with cutting cord. To work with the spool, only narrow fishing line is used. The body of the model is made of durable multilayer plastic.
