In the modern agricultural economy, a lot of all kinds of tools have been developed that are designed to make life easier for summer residents and amateur gardeners. In my opinion, the grass trimmer type lawn mower is one of the very simple and ingenious inventions that can turn your weed-covered garden into a well-groomed lawn in a matter of minutes. But no matter how thoughtful the invention, it needs care and repair. I am not a supporter of reworking industrial tools, but in order to save money, I came up with and describe a useful addition to the line trimmer.
Line trimmer, do-it-yourself repair:
When you start a power tool on the farm, you should immediately understand that in addition to the electrical part, there is also a mechanical one, which requires timely maintenance, cleaning, cooling and lubrication. The line electric trimmer is no exception. I’ll tell you a little about my trimmer, I don’t indicate the model and parameters - this is not so important. The first thing that was covered in it was the button, when I took it apart, there were obvious signs of melting, I think it was caused by power surges in the network and the processes occurring at the time of switching. And to put it simply, it was of poor quality. Like many other parts of the trimmer, the button can be replaced with another one that is suitable for the parameters (current and design). The fishing line for the trimmer, well, in other matters, like other attachments, is a consumable item, and it is quite natural that I also ran out of it. As a typical Kulibin, I started to stick everything that came to hand there, starting from an ordinary thick fishing line and ending with a thicker and more durable special line for a trimmer. Despite my natural curiosity and inquisitiveness, I acted within the framework of the instructions I read, but even this did not save my coil from destruction.
Coil from my trimmer 
Coil side view As if the reel (meaning the very part where the fishing line is wound) didn’t suffer much during my experiments, but the special grooves holding the fishing line just wore off, it’s not surprising because they are plastic, and I have been using the trimmer for a long time and quite often. Of course, spare parts are sold even for old models of trimmers, ranging from fishing line to engines. But the new reel seemed a little expensive to me, the price, let’s say, “bited”, and I was not satisfied with the fact that you couldn’t fill the line with a thickness of 5mm (my trimmer is designed to use a line with a thickness of 2mm).
And so ... after much thought on how to modify the trimmer coil, an idea that was easy to implement and quite easy to use came to my mind. It is necessary to cut a circle from a strong material, I used 4mm thick foil textolite.
PCB disc with holes You need to make a hole in the center of the disk that is suitable in diameter to the axis of the rotating shaft, and four more holes (or more) that are suitable in diameter for your fishing line.
Disc and pieces of used fishing line The idea is very simple, you don’t use a spool, you don’t wind the fishing line, but simply tie it to the holes and attach the disc to the holder according to the same principle as the previous spool, it’s only important to find a suitable spring - for fastening reliability (whoever has a trimmer will immediately understand about which spring are you talking about?
We tie pieces of fishing line to the disk 
We fill the fishing line and attach the disk to the holder The fishing line can not be tied, despite the high speed, it somehow keeps quite firmly and does not fly out. With the proposed organization of the direction of the fishing line to the trimmer, you win in that you can catch fishing line of any diameter and configuration there, while you will never need to spend money on new reels. But there are also disadvantages, you will need to cut pieces of fishing line of a certain length, this may not always be convenient. But in terms of time and laboriousness, refilling the fishing line is neither a little nor worse than in the classic way into the native reel.
This is what my version looks like I took a photo without a trimmer and a retaining spring, since it was not at the cottage at that moment. But I can safely say that the result of my revision exceeded all my expectations. Now I have significantly reduced the cost of consumables for the trimmer, which once again proves the triumph of reason over the dogma of the instructions that come with purchased tools.
Trimmer heads are used for cutting grass and lawns. Such a device has a fairly simple device and is easy to operate. Thanks to this, the unit has become popular with the population and utilities. Light weight is an additional plus, almost anyone can cope with the work of such a device. Consider the features of the unit and reviews of manufacturers.
Description
Trimmer heads include a cutting element, a special rod, a mover and a control mechanism with a handle. The unit is designed for cutting grass in the courtyard area and garden plots. The compactness of the device and ease of operation allow you to do high-quality work in the most inaccessible places. With the help of this unit, you can also trim shrubs and a young garden. Adjustable elements allow you to set the desired cutting height of grass on lawns and playgrounds.
When choosing trimmer heads, pay attention to the following parameters:
- Power indicator.
- The weight of the device.
- Power type.
- Placement of the engine, which can be top or bottom.
- Type of cutting piece.
- Rod type.
Classification by type of line supply
Husqvarna trimmer heads are classified according to the way the line is fed, as follows:
- Manual type. The feed of the fishing line in this embodiment occurs by a mechanical method. To lengthen the cord, you will need to stop the device and pull out the edges of the cutting part with your hands.
- semi-automatic. Such instances allow the replacement of the cord without touching the head of the ground. This option is feasible with the help of a special key and an anchor mechanism that makes it possible to lengthen the working part of the fishing line due to centrifugal action. It is important that the whole procedure is carried out with the unit turned on.
- Automatic trimmer heads differ in that during their operation, the extension of the cord is performed automatically after a decrease in engine speed. The feed line is carried out in the normal mode.
Of the above mechanisms, the manual version is not very practical and convenient. Automatic variations are also not popular due to the high consumption of fishing line. The optimal version will be semi-automatic execution.
Criterias of choice
When purchasing Champion trimmer heads and other models, you need to focus on the purpose of using the unit. For a large area with a flat lawn surface, it is better to use light and not very powerful modifications. If it is planned to process an overgrown summer cottage, it is more reasonable to take a model with a high power rating.
The selection of the cutting element also plays an important role in the final functionality of the unit. The working part is a special fishing line or working knives. This takes into account the stiffness and density of plants. The universal trimmer head will allow you to process most of the vegetation, but it is not always durable and efficient.
Device
The device in question is a coil of a special configuration, which is equipped with an internal cord. It can have different sizes, it is wound on the inner element of the spool up to 15 meters long.
The edges of the fishing line are set at a certain distance for the possibility of work. When it hits hard objects (stones, trees, etc.), the working element is destroyed. Depending on the type of fixture, the heads may have a different configuration. Universal analog is suitable for most modifications. This is due to the possibility of using a number of special adapters.
Filling the line
According to this parameter, trimmer heads can be divided into two categories:
- Fast charging. On such models, when winding the cord, it is not necessary to disassemble the coil. One edge of the next refilled fishing line is wound into a reel and wound several times. After selecting the desired length, the material is cut off.
- Collapsible heads. To refuel them, you need to remove the reel from the unit, then remove the used line and wind a new analogue.
The working head contains special pointers in the form of arrows. They are responsible for the direction of movement of the working part during rotation. If it is necessary to wind the fishing line in the direction of rotation of the shaft, it is turned into a certain position. An excessive amount of cord is fraught with equipment failure.
If it is impossible to wind the cord after a blow on the semi-automatic head, the winding should be performed again. Most likely, the user did not pull the ends of the scaffold out of the nests.
Popular Models
Consider briefly the representatives of the most famous manufacturers of spools on the domestic market:
- Trimmer head Oleo Mac M-10/11.25. This model belongs to the professional semi-automatic options, used in the operation of lawn mowers. The diameter of the working part is 13 centimeters, it is distinguished by a quick filling of the fishing line.
- Husqvarna T-45X- has an open eye, easy giving of a cord. Work items can be changed individually. Increased reliability and reduced wear are ensured by a bearing surface with a ball bearing.
- Husqvarna T-35. This model is a head with automatic line feed (just hit the spool lightly on the ground). There is a tap and go function.
- Champion. Modification ET 1002KA belongs to the middle price category. Differs in simplicity in dismantling, strong vibration during the work is not felt.
- Trimmer head DDE. The Win 6 type variant is designed for cutting grass with a fishing line with a diameter of 2-3 mm. Suitable for electric and petrol mowers with 10 mm working shaft. The maximum allowable speed on the shaft is 10 thousand revolutions per minute.
- Autocut C-4-2. This head is suitable for Stihl lawn mowers, used for mowing grass and cleaning the area. There is an automatic adjustment of the length of the working strings when the head touches the ground. The model is compatible with 2 mm line.
Exploitation
When the cord meets solid objects, it stops abruptly, as a result of which the line gets inside the device. She lies under the spool and sticks together. To correct the situation, you will need to stop work and lay the fishing line again. As a prevention of such inconveniences, it is recommended to treat the line with silicone grease before installation in the reel.
In the device of the trimmer head Autocut, like other semi-automatic models, two parts of the main element are distinguished: the body and the spool. Both parts are provided with spring mechanisms. The spool can be made in several configurations:
- Modifications with one section. In this case, both ends of the line are wound together.
- Models with a couple of compartments. In them, each edge is wound onto a specific element. This design is more efficient, avoids tangling of the scaffold and its sintering.
It is quite possible to redesign a single-section spool into a version with two chambers. This will require a strong plate, from which a circle is cut with a diameter identical to the thickness of the spool. This item is in free movement. Then an incision is made on the ring, mounted on the head and fixed with adhesive tape or glue.
Peculiarities
The universal trimmer head can be equipped with two to four holes. They are opposite each other. From these elements, the ends intended for mowing are derived. In addition to the indicated types of spools, there is a head designed for a certain size of the line. In such coils, the number of whiskers increases to a dozen. Among users about such devices, opinions are divided.
Some consider such a unit more efficient. Others are sure that the line consumption will be significantly higher with a dubious improvement in the quality of work. In addition, to replace the scaffolding, it will be necessary to interrupt the process. When choosing a trimmer, consider the terrain and vegetation characteristics. After that, you can choose the option that is best suited in a given situation.
The trimmer coil cuts the grass, but it wears out and often needs to be replaced. Recently, motorcycle or electric scythes have become widespread. The main working element of such a garden tool is reels with line tucked inside. Therefore, it is extremely important to choose a quality element so as not to waste money, because the device is quite expensive. To reduce the cost of maintenance of lawn mowers, you can learn how to fill the forest into the trimmer coil yourself.
Often, manufacturers of power tools do not complete their products with a number of necessary or useful devices for work, offering to purchase them separately (as an additional option). With a scythe coil, the situation is different: since this is the main working element of a garden tool, all trimmers are supplied with it, but the quality of the coil from the scythe kit leaves much to be desired.
The consumer has to purchase the coil separately - this is done to increase sales and generate additional profits for manufacturers.
Below are questions about what a trimmer is, what coils are and how to insert and secure the fishing line on your own.
What is a trimmer
Under the trimmer mean scythes or electric scythes. In fact, this is one of the types of lawn mowers (hand mowers) that are designed for mowing grass. This is a modern braid. Initially, they were developed for agricultural work, but lawn mowing became the main use of trimmers.
For the first time, the idea to create a trimmer came up with the American entrepreneur J. Bollas. Driving his car through an automatic car wash, he noticed that the principle of rotating brushes could be used to mow crops.
After that, he assembled a primitive trimmer from a tin can (as a reel) and a fishing line threaded through holes drilled in it. He installed the resulting design on a pole, on which the engine from a moped was previously mounted. The device mowed not only wheat, but also grass. Realizing that he would earn a lot of money by selling the scythe, the entrepreneur improved his product and gave it the name "Weed Killer". A feature of the invention was the ability to mow the grass around the trees - the forest perfectly cut the grass, but did not injure the bark.
The main purpose of such a tool was to mow grass in small areas in places where classic wheeled vehicles cannot be used:
- in the presence of a large number of shrubs;
- in gardens with a lot of trees;
- near fences and fences;
- if the area has uneven terrain.
All trimmers incorporate a rod - the main structural element. A gasoline or electric motor is attached to the rod at one end, and a reel with fishing line is put on the other - the main working element. In this case, the type of transmission can be any - it is limited only by the capabilities of the manufacturer and commercial parameters.
Why is this tool called differently
The trimmer was originally understood as a manual lawn mower with an electric motor. At the same time, the mower was powered both from the mains and from the battery, which can be installed on the bar or carried in a special pouch.
The main cutting element is a fishing line, which creates some restrictions on the type of grass being processed: only plants with a thin and soft stem can be mowed. The mowing area is limited by cable length or battery capacity. However, recently, gasoline-powered braids have also been called trimmers. They give greater mobility to the worker, which can significantly increase the size of the site.
But electric and gasoline scythes were originally varieties of lawn mowers, however, with the advent of the trimmer, these designs have ceased to be in demand and are now rarely produced, and their names have moved to trimmers - most people are more accustomed to calling this tool.
Coil specifics
In the modern world (both in the city and in the village), it is practically impossible to do without such a modern and useful tool as a trimmer. It is widely used by employees of public utilities in large cities, such devices are also in demand in farms, they are used to improve summer cottages, vegetable gardens, gardens, etc.
Photo of a complete set of a garden trimmer coil.However, it should be remembered that the main working element is the head for the trimmer - a spool of fishing line. It is this element that most often fails and requires care. The price of coils has a wide range (from 10 to 150 dollars), which makes such a tool even more expensive. Any manufacturer (even a branded one) usually completes its product with an inexpensive and low-quality coil. However, it is possible to work for quite a long time with a primitive coil, provided that the work on caring for it is carried out in a timely manner.
Like any other mechanical element, the coil requires cleaning from crowded grass, cooling during overheating and filling with lubricant. However, coils often fail for various reasons, and buying new ones or carrying broken ones for repair is quite expensive. In this case, almost all malfunctions can be eliminated independently. Disassembling the coil is not difficult, especially if you follow the instructions.
The first part that often fails on a trimmer spool is the line. The fishing line is a consumable item for which the manufacturer is not responsible. At the same time, on many models of reels, replacing fishing line is a complicated procedure (and for some brands it is impossible). Attempting to replace the line with a material different from the parameters of the original line may lead to the destruction of the reel.
The reel itself (the part of the element on which the line is wound) rarely fails, while the grooves through which the working part of the line is threaded and which hold it can collapse (grind off), since they are almost always made of plastic.

Despite the abundance of spare parts for trimmers on sale, not everyone can afford to buy them, in addition, there are often restrictions on available products. For example, manufacturers make “individual” mounts for a trimmer, a universal coil will not fit on such a mount. This often makes it impossible to purchase a suitable reel for the price. Some manufacturers make reels designed for thin line (up to 3 mm in diameter), which significantly limits the capabilities of the trimmer. Therefore, there is an option for self-manufacturing of the coil.
How to make your own coil
The basis of a homemade coil is a disc made of durable material. It is best to use textolite about 5 mm thick for these purposes. It is quite strong and reliable. The size of the disk depends on the dimensions of the trimmer and personal experience - how it is more convenient to work.
Next, a hole should be drilled in the center of the disk. The diameter of the hole must be equal to the diameter of the axis of the rod (the latter is attached to the rotating shaft of the engine). In this case, it is extremely important to determine exactly the center of the disk. After that, you should drill 4 holes for the fishing line. Their diameter will be equal to the diameter of the fishing line, and they will be located in pairs on opposite sides of the axis (2 on one side, 2 on the other from the axis of rotation). In this case, the design of the reel is greatly simplified: it is not necessary to wind a large amount of fishing line, but it is enough to fix (tie) a small segment of it through the prepared holes.
To give the structure the necessary strength and reliability, it is recommended to find a spring, the inner diameter of which will be equal to the diameter of the shaft, and install it on the shaft on top of the finished disk.
After the fishing line is tucked in and fixed on the disk, you can start testing. The fishing line may not be fixed to the disk motionlessly: even if it is threaded through the holes, it will not fall out, because the engine gives high speed to the shaft, and the centrifugal force is enough to hold the fishing line under load.
This design, instead of a purchased coil for a trimmer, has many advantages: you can install any fishing line (both thin and thick) into it, the device itself is practically “indestructible”, and it will not take a very long time to purchase a new coil.
The disadvantages of this homemade product include the following:
- the need to cut a pair of pieces of fishing line of the same length;
- when installing without attaching a fishing line, it is necessary to make sure that equal lengths of fishing line hang from the reel.

The body can be used from an old coil - it rarely breaks.
Conclusion
Such a homemade coil can significantly reduce the cost of operating the trimmer, which improves its performance. You can use the same trimmer to cut both small shrubs and soft and thin lawn grass.
To look after the lawn near the house or cottage, you can not do without a trimmer. As you know, the coils of these tools wear out quickly. However, in this case, much depends on the vegetation with which the person is fighting. If we talk about one-year-old grass, then the wear of the coil is extremely small. However, weeds are very difficult to control.
How to choose a model?
The market is mainly represented by plastic modifications. They are made with steel cores. First of all, you should pay attention to the diameter of the fishing line. For one-year-old grass and small weeds, a size of 1.5 mm is suitable. The coil height must not exceed 80 mm. The winding system is most often used semi-automatic type. However, there are models that only work when touching the ground. Thus, the line wears out much more slowly. There is such a modification in the region of 800 rubles.

The trimmer is a simple and very popular device that helps to keep lawns, flower beds, parks and gardens in order. Its main advantages can be safely:
- versatility - by changing the cutting element (fishing line or a special knife), you can mow not only grass, but also dense shrubs, vines and shoots of young trees;
- ease of operation;
- relatively small weight.
Such a mowing unit can be powered by an electrical network, a battery or a gasoline engine. Depending on the energy source, the trimmer package is different, but the trimmer head remains one invariable element in all models. In some instructions, these parts may also be referred to as a coil.
Trimmer head (coil) - types, features
This element of the trimmer is a special coil on which the cutting cord (fishing line) is wound. It is the ends of the cord, which are advanced to a certain distance at high speeds, that mow the grass. It is worth noting that a reel with a cord can only be etched with low grass, but tall weeds, vines or shrubs can destroy the cord.
Today, a coil for a trimmer of various designs is found on the consumer market. Specialists divide coils into the following types:
- manual - to adjust the length of the cord, it is necessary to stop the operation of the unit and manually pull out the fishing line;
- semi-automatic - cord adjustment is carried out with the engine turned on, control is carried out using centrifugal force, just press the button on the handle;
- automatic - to change the line, it is enough to slow down the trimmer, after which the speed is increased and the line will automatically lengthen.
From these descriptions, we can conclude that the manual coil on the trimmer is the most inconvenient design. The automatic design of the reel is convenient during operation, but has one drawback - it is not economical, high consumption of fishing line. Therefore, the best option is a semi-automatic design.
