Coil for trimmer for grass is universal: choices and reviews

Coil, or, as it is also called, a head for a trimmer for grass is one of the types of cutting elements of a garden tool. Its main function is the timely supply of fishing line for uninterrupted mowing of grass on the site. Not only the speed of the trimmer for the grass depends on the serviceability and condition of the spool, but also its effectiveness when working in different operational conditions.

All heads for trimmers are previously divided by type of supply of cutting fishing line. Depending on this factor in the market, you can find the following types of devices:

  • manual. in rogues of this type, a fishing line for a trimmer must be served manually. To draw out the right amount of cutting cord, it is required to stop the work of motorcycles, and lengthen the ends. A hand reel for a trimmer for grass is considered the most reliable of all types. Nevertheless, it will require a certain dexterity, which can only be found with constant operation of this type of head;
  • semi.automatic. in order to lengthen the ends of the cutting cord, the lower end of this device will use to press to the ground. In this case, the operator must click the button that opens the anchor mechanism. At this time, centrifugal forces are triggered inside the spool, under the influence of which the fishing line for the trimmer lengthens the value of the necessary for further work. The semi.automatic coil for a trimmer for grass does not require dexterity. The only negative is high for some models of these devices;
  • automatic. heads of this type do not need to stop the work of a trimmer for grass and do not require dexterity. The cutting cord in them is lengthened independently during the drop in engine speed motorcosa. The automatic head of the trimmer for grass is the most convenient device, however, due to its more complex design, the owner is forced to repair the device more often.

In addition to the listed species on sale, universal coils are also found. They are in high demand due to the possibility of installation on trimmers for grass from different manufacturers. In addition, these devices have a low price, and they can be found in any garden product store.

In addition to the classification by the method of feeding fishing line, the spilles for trimmers are initially divided by each other, and the method of charging by the cutting cord. The following types of devices are found depending on this factor:

  • Fast-got their name due to the fact that when the new cutting fishing line is not required, the operator does not need to remove the head from its base. This makes it possible to save time and the operation of a trimmer for grass is more convenient. For refueling, you need to put one of the ends of the new cord into its hole, and wrap it around the head several times. After reaching a certain value, the second end of the fishing line must be cut off;
  • Cleaning type coils. to refuel them, the operator will need to turn off the ignition and remove the coil from the trimmer for the grass. After that, a new cutting fishing line for a trimmer is wound instead of the old. At the end, the operator will have to assemble the head and install it in the regular place.

Most of the coils for motorcycles include sprayers that can be one- or two-section. In devices of the first type, the used fishing line for a trimmer is wound evenly on each side. In two.section mowing heads, each of the individual parts of the cord must be wrapped on a certain part of the coil. The devices of the second type are considered the most convenient to use since the fishing line for the trimmer in them does not bend at sharp corners and is not deformed.

How to choose a model?

The market mainly presents plastic modifications. They are produced 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, the size of 1.5 mm is suitable. The height of the coil should not exceed 80 mm. The wrapping system is most often used in the semi.automatic type. However, there are models that work only when touching the ground. Thus, the fishing line for the trimmer wears out much slower. There is such a modification in the region of 800

The indicated coil for a trimmer for grass universal reviews from buyers mainly receives positive. First of all, the low weight of the model should be noted. The width of the presented modification is 72 mm. The manufacturer’s wrapping system is provided for semi.automatic type.

Fishing line for a trimmer for the head is selected with a diameter of 1.3 mm. The model copes with the one.year.old grass wonderful. As the owners note, wear of the coil is extremely low. With large weeds, owners may have certain problems. It is the cup that breaks most often. The presented coil is worth in the region of 650

How to mow grass with a trimmer with a metal knife

As the border of the mowing area moves, move the fuel and the bag.

If the grass was setting down: you need to hand the steering wheel forward and mow to the left with an inclination by the handles to the left (sector ~ 11 hours) and the right with the tilt for the handles to the right (sector ~ 1 hour), and do not rush!, to mow the grass cleanly and so as not to “dig” the earth.

During the mowing of grass (and turns), do not forget to look around!:

  • To notice the gesticulation of others, drown out the motor and remove the headphones,
  • So that closer than 15 m children, animals, spectators and assistants do not come up, t.to. When a metal knife in the grass collided with a motionless object, a trimmer for grass or a lawn mower (motorcycle) can be strongly thrown to the side or expanded back, and a trimmer for the grass rotates at a speed of up to 10,500 rpm. And he is able to cut off his hand or leg. Also, when the grass is mocking the trimmer from under the knife, various objects (crushed stone, glass, garbage) can fly out and ricochet).

How to mow grass with a trimmer (more about the mowing technique)

The engine revolutions when the trimmer mowed depending on the load on the engine. the thicker the grass and, of course, is heavier than the engine, the bolder you need to open the “hole” (throttle in the diffusor of the carburetor).

Work speed of the engine during the mowing of grass with a trimmer try to keep constant (slightly higher than medium). or less gas. only depending on the overall load on the engine. No need to completely discard gas (and immediately acceleration again) with each wave of braids for grass. And the clutch is not for long, and the edges on the drive shaft can “overtake”, and the overall wear of the trimmer for grass (motorcycles) increases sharply.

Before mowing grass, we find out the parameters of the site

(to know which knives to take, how much fuel and time are needed)

  • Grass density;
  • The hardness of the grass;
  • the splendor of the grass;
  • wovenness of grass;
  • (The height and thickness of the grass are not important)
  • the boundaries of the site;
  • what irregularities (how to come in);
  • the presence of hidden obstacles (remember)
  • that not cut (bushes, flowers, seedlings).

To mow grass in the summer is a disaster, and not just homework how to use a trimmer. If your yard or site is strongly overgrown with grass, you can scare you, but this part of the article will help to figure out how to mow grass with a trimmer easier and less irritating.

Sharpening of blades

The aim of sharpening is to eliminate the small chips of the edge and remove the descent into one straight plane. The presence of a “saw” on the blade leads to a rapid decrease in sharpness, and with a rounded descent, there is a too strong effect on the cut stems. In addition, the blade with a rounded shape is polluted much faster.

The sharpening of the blade is best done with a flat sandpaper grain of about 400-600 grit, more “delicate” stones do not make much sense. Soak the bar in the washed water for 10-15 minutes and periodically moisten during turning. The knife is also sharpened on grain with a small length of the bar from the center of the sharpened area to the edge.

When sharpening, try to adhere to the same position of the stone to maintain a permanent angle. As with the removal of descents, sharpening should be carried out with the condition that the same amount of metal is removed on the opposite blades. This condition, however, is not necessary to strictly observe when sharpening four.lobed knives.

TOP-3 most reliable coils for domestic use

The market has its own rating of the most durable mowing heads. They are distinguished by the simplicity of the device, reliability and resistance to damage. They include:

  • 3rd place-Bosch K-103. This is a universal coil weighing about 300 g. Most often it is used to equip a motorcycle company Makita and Hyundai. The model is highlighted by a low flow rate of the cutting cord, resistance to blows and durability. The core and its other spare parts are made of forged steel, and the case is made of plastic;
  • 2nd place-Flymo 15. This semi.automatic model for trimmers is equipped with a thin cup, which leads to an increased consumption of cutting fishing line. However, she showed herself well when mowing grass in rocky terrain. To work with it, you need to use only a thin fishing line for a trimmer;
  • 1st place-EFCO 8100. This model is one of the most reliable mowing heads. It works in fully automatic mode, which simplifies its refueling by the cutting cord. Only a thin fishing line for a trimmer is used to work with a spool. The body of the model is made of durable multilayer plastic.

Despite the stability and durability, all of the listed coils cost an order of magnitude cheaper than other, less high.quality analogues, which makes them leaders in the market of the post.Soviet space.

Despite the fact that any fishing line for a trimmer mows grass, its main parameters greatly affect the efficiency of work in various conditions.

A cutting string that can effectively cut the thickets of weeds or shoots of young shrubs can easily cope with low lawn grass, but a fishing line for a trimmer for lawn grass is useless when weaving weeds or overgrown with bushes.

Now you know the basic characteristics of the trimmer fishing line, as well as the influence of each of them on the effectiveness of mowing various types of grass, which means you can choose the right cutting string corresponding to both the situation on your site and your trimmer.

Criterias of choice

Before buying a spray, you should contact the documentation for a trimmer for grass, which indicates the recommended parameters of the mowing heads, the thickness of the fishing line, the diameter of the landing hole for the coil, type of mount, thread (left or right) and a fixation axis (stiff or rotating at 90/180/ 360 degrees). The same information is indicated on the packaging of consumables along with models of technology, on which you can install a specific head.

  • Of the three types of coils by the method of serving fishing line, it is better to choose semi.automatic. They are more convenient. Among these spools are quick.charged models, as well as universal samples designed for different trimmers and with holes for a fishing line for a trimmer of various thicknesses. With this head, you can mow two or three types of grass: soft lawn, wild and tall, with hard stems. For each type of thicket, you will need to buy only a cord of a suitable section, and not a separate coil.
  • If only vegetation of a certain type is to mow, you can stop on a coil under a fishing line for a trimmer of one diameter. Knives or discs will cope with other tasks.
  • Too cheap cutting of brittle plastic heads quickly break, so excessive savings can turn into new expenses.
  • You should not install the coils of little.known brands for trimmers for grass from eminent manufacturers. Popular companies are produced by components that are best for equipment of the same brand.

Often market leaders produce coils for trimmers of 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 electrimmers of the same brand, but is also recommended for use on mower mowers Greenline and MTD.

On a note! Some coils are designed to work only with trimmers of one manufacturer, although the lineup can be quite wide. So, the T25 head for the Husqvarna 128R gasoline apparatus is suitable for three dozens of travo.shirt models of the same company.

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

How to refuel a fishing line for a trimmer in a coil semi.automatic trimmer for grass

Warranty production of the factory refueling of a trimmer for the grass will be in demand to change fishing line. Having a very indicative idea that how to tuck a fishing line for a trimmer to the coil of a trimmer for grass without the help of others, the new ones without hunting take up this matter. But with some abilities, the development of this simple science does not represent any difficulties, and the similar annotation presented below will greatly facilitate such a process.

First, for winding the fishing line, it is necessary to remove the coil (bobbin, spool) from the trimmer for the grass. certain acts will depend on the difficulty of configuration and the type of product itself:

  • Small electronic trimmers for grass with a working location of the motor and coils in the bottom, usually have side buttons on both sides of the bobbin. With the simultaneous pressing of them, the highest part of the coil, together with the internal contents for winding the fishing line, is disconnected, although the lower one remains on the trimmer. The analysis of the bobbins is better to create in an even smooth place, so that the spring entering the design does not jump out and does not even get lost;
  • Electronic and gasoline trimmers for grass with a curved rod without the ability to install a knife, you have coils with a special lamb: in similar structures, you should hold a spool in a motionless position with one hand, and turn the fixing bobbin on the stalk a barack nut. After disconnecting the nut, the whole bobin is removed.
  • Electronic and gasoline trimmers for grass with the ability to install a knife on a straight rod (for example, trimmers for STIHL grass) have a hole. For the immobility of the bar, a screwdriver or another suitable object is inserted into this hole and with unhurried rotation, such mutual placement is achieved when the screwdriver enters the holes and the bobin is fixed. Then the coil body is scrolled clockwise (with left thread) and removed from the trimmer for the grass.

How to wind a fishing line for a trimmer in a trimmer coil (Spool).

For the second and third options of coil, depending on the design, are versed in different methods. In the bobbins with a lamb, lamb is twisted, in the reels with the latches, the fixers are pressed and one part of the coil is freed from the other. If the halves of the spool are connected by thread, then they are quite turned with their hands in the back sides until they are completely developed.

Solving possible problems with fishing line

Most of the problems associated with the fishing line are similar to different trimmers and are solved in a similar way.

Turning the string

  • the presence of solid objects in mowing grass: branches, stones, etc.D., contact with which the string breaks off;
  • Powder of grass is close to the fence, and if it is mesh, then the fishing line for the trimmer is torn even faster;
  • low.quality cord. it is necessary to replace with a new reliable consumable;
  • wear of the output holes in the mowing head, as a result of which the fishing line for a trimmer breaks off from friction on the sharp edges of the bushings. it is required to replace parts with a new.

Large fishing line

Typically, a fishing line for a trimmer ends very quickly if you constantly knock a semi.automatic coil on the ground or press it with an effort to the surface. In this case, the head is unlocked, the cord is lengthened, and the knife cuts it. The second version of the fast consumption of fishing line is a trimmer for grass with an automatic coil is incorrectly used. If the mower regularly lowers the engine speed, the string is constantly lengthened and cut and as a result is quickly consumed.

The string does not hold

If the spring weakens the semi.automatic type in the coil of the semi.automatic type, the fishing line for the trimmer does not stay and is unwinded during operation. The cord is extended, cut off with a knife, as a result, the owner of the equipment notes that the thread quickly ends.

Advice! To check the tool, you need to remove the protective casing and start the engine. if the fishing line for the trimmer is advanced, this means that the spring must be changed to a new one.

a fishing line for a trimmer flies out

If the string flies out with kosbe, this is another evidence that the spring in the bobbin is weakened or completely lost with an inaccurate analysis of the head. As a result, the cord does not hold and pops up when rotating.

The string is not advanced

In the coils of automatic and semi-automatic cords, the cord is served without stopping the trimmer for grass. If this does not happen, then:

  • The fishing line for a trimmer in the head is wound wrong, so the coil does not spin;
  • The winding of the fishing line is made unevenly, so the cord stuck between the turns and does not go out. so that this does not happen, you need to wrap the thread carefully, preventing distortions, a turn to the turns;
  • The ends of the cord emerging from the holes are very short, centrifugal force is not enough to extract them, so the fishing line is not served-before turning on the trimmer for the grass, it is important to control the length of the thread and slightly lengthen it, if necessary;
  • The cord is stuck.

The coil does not spin

The reasons why the coil does not spin are similar to the lack of fishing line. This is the wrong or uneven winding of the string, its sticking, as well as the short ends of the cord, emerging from the holes.

Trimmer fishing line sticks together

If when working a fishing line for a trimmer sticks together, the main reason is the installation of a low.quality cord. In the course of work, the coil is heated, and a poor.quality string melts and glued. The second reason is the clash of the cord with solid objects. In this case, its sharp braking occurs, the thread is drawn into the head and picks up.

Advice! To avoid problems, you can apply mineral oil to the surface of the fishing line or, after winding on the head, spray it with silicone. A more competent solution will be the acquisition of a good high.quality head, which will forget about such problems.

So, replacing a fishing line for a trimmer on a trimmer will not be difficult if you know how to disassemble the coil and wind the cord winding. This process is similar for technology of different brands. A detailed description can be found in the instrument operation instructions or watch on the video.

Trimmer heads: types and principle of action

The domestic market offers the owners of trimmers of the coil of several types: manual, semi.automatic, automatic and universal. They differ from each other in both the way of serving the fishing line and the principle of its charging. You can also wound a fishing line for a trimmer in different ways. According to this principle, the coils are classified into quick.charged and collapsible.

Before you purchase a trimmer for grass and/or buy spare coils for it, you must definitely familiarize yourself with which consumables are suitable for a particular model. This is important, since bobbins of different manufacturers can differ not only in the methods of supply and refueling of the cord, but also to the axis of the mount, type of thread, as well as the diameter of the fishing line used. For example:

  • The fastening axis can be fixed (fixed) or rotating 90 °, 180 ° or 360 °;
  • For low.power trimmers, a fishing line for a trimmer with a diameter of 1.3 to 1.6 mm is suitable, and for more productive. up to 2.0 mm;
  • Professional trimmers for grass, as a rule, are equipped with universal heads with a diameter of the cutting cord from 2.5 to 4.0 mm.

Advice! Experts recommend using string heads equipped with ball bearings, as they have an increased service life, while reducing the wear of incoming components. At the same time, for replacement, it is best to choose the bobbin of the manufacturer indicated in the operating guide for the grass for the grass, which in turn will allow you to correctly install the head on its drive.

Manual bobbins

A manual mowing head is a coil in which the cutting cord during wear is stretched by the owner of a trimmer for the grass on its own. To do this, turn off the tool, remove the head and with the help of hands stretch the fishing line for a trimmer to the required length. However, despite some inconvenience, this type of head is considered the most reliable.

Bobbins with semi.automatic control

The semi.automatic coil installed on the trimmer allows you to serve a fishing line for a trimmer using the centrifugal force that occurs when it rotates. In order for the supply to be carried out, you need to touch the head of the coil to the ground and at the same time press the button that opens the anchor mechanism. This key is located on the control handle. At the same time, turning off the trimmer for the grass is not required.

On a note! In the market of trimmer spare parts, semi.automatic coils of two types can be found: single.section, in which the fishing line for a trimmer is wound evenly on both sides, and two.section, where the cutting cord must be refueled separately in each section.

Bobbins with automatic control

In the automatic heads, the supply of the cutting cord occurs when the speed of the trimmer engine is changed. To pull the fishing line for the trimmer outward, reduce, and then increase the speed of rotation of the engine shaft. As a rule, the coils of this type are equipped with a metal core, due to which their breakdown is practically excluded.

Bobbins are universal

The universal type of heads differs from its analogues in that they can be installed on various models and electrimmers’ models. They are characterized by high strength and reliability during operation.

choose, trimmer, head, string, sticks

Bobbins are quick.charged

Coils of this type allow you to refuel a new fishing line for a trimmer without disassembly. To do this, one of the ends of the cutting cord is stuck inside the bobbin, and then wrapped several times around its surface. After the required amount of fishing line is wound, the latter is cut off.

Bobbins collapsible

To refuel the fishing line into the head of this type, it must be removed from the grass.shirt and disassemble. Having wound the required amount of cutting cord, the coil is collected and returned to the place.

On a note! Currently, almost all electro- and benzotrimers are equipped with mowing heads that allow the fishing line for the trimmer to change to the knife.

Opinion about coils for trimmers Flymo 15

This coil for a trimmer for grass (universal) is made with an automatic wrapping system. The cup in it provides for a small thickness. Buyers complain that she wears out very quickly. However, it is important to consider the small price of the goods. The height of the installed head is 74 mm. A small dimeter is used directly for the trimmer. The core in this case is made completely of metal. Suitable head for garden trimmers of various manufacturers. You can find the indicated coil in the market for 700

This coil for an electric trimmer for grass (universal) is made with a reliable wrapping mechanism. The mounting diameter in this case is 6.5 mm. The height of the installed head is 72 mm. A model for trimmers “Hyundai” and “Makita” is suitable. If you believe customers, then the head is unwound very quickly. The model copes with the one.year.old grass without problems.

According to the owners, the casing of the coil uses high.quality. In this case, the cup practically does not wear out. However, when working, it is important to beware of large weeds. The user is capable of purchasing this model for 1200

And yet: a cart or a trimmer for grass?

The trimmer for the grass must be held in the hands, and large models (motorcycles). also “put on” with the help of special mounts. The cart is taken in front of themselves, so the choice depends on the tasks and in many ways. on the physical capabilities of the user. So, a large trimmer for grass. especially gasoline. is quite heavy, and it is difficult to work without good physical training.

First about the pluses. An electric or gasoline trolley with a rotary knife (such a majority) provides an even equal height of the cut of grass (when forming a ground lawn, the height of a bevel is critically important: there are certain rules at each stage, without their execution you will receive a trimmed area, but not a lawn in any way).

The user spends a significant part of the time of work with the cart on the removal of mowed grass from the grass collector and its disposal (it is convenient to have a wheelbarrow nearby, in which you can dump the beveled), however, the presence of a grass collector has a big plus in carts. The grass does not fly in the face of the user and he does not need a protective mask; No need to collect mowed grass with a rake, you can immediately send it to compost. Some models have built.in grass grinders (mulching function, mulching the knife), turning it into finished fertilizer for the lawn and immediately scatter crushed grass on the lawn. Such models are often more expensive, but get rid of the need to shake the grass collector and think what to do with waste. Minus of using the chopper: you need to protect clothes, shoes and face from flying chopped grass.

The carts also have common disadvantages: they mow grass with a maximum of 80-100 cm high. and then in this case they will constantly slow down and clog. especially less powerful, electric. That is, for overgrown sites, the trolley is not suitable: first it is necessary to clear it with a trimmer (motorcycle). Tails often lack maneuverability. for example, to carefully circumvent cultivated plants or to bite small areas between them, as well as zones in front of fences or borders.

Selection of lawn mowing, depending on the area of ​​the site

For 6-9 acres, an electric lawn-bore-mushroom is suitable. If the surface of the site is leveled and there is no strong shoots of fruit trees and undergrowth, the device consumed by a capacity of 1000 W is enough. If the site is often overgrown (for example, you are on it once or twice a month), if there are height changes (pits, mounds) or shoots. the power of an electric lawn mower should be higher: 1.5-2 kW.

For plots with an area of ​​10-15 acres, it is worth thinking about a gasoline or battery lawn-bore. Exception. if, except for the house, there are buildings with electricity on the site (bath, garage, household), where you can easily connect the lawn mower. Changing the connection location to the network, it is quite possible to get by with an electric device. Sections of a larger area to process an electric lawn mower are extremely difficult or impossible.

And there is another interesting solution for very small areas: compact batteries combining a housing with a rotary knife (like a cart) and a long handle (like trimmers).

Selection of lawn bores, depending on the type of lawn

Most rotary lawn mowers have a adjustment of the height of the cut of grass, and for normal care for the site this is quite enough.

But if you want to achieve a perfectly even lawn and you do not have a too large site, then you should choose the lawn mower not rotary, but drum type. These are mechanical (!) lawnmands (and not quite trolleys), the cutting mechanism of which is a cylinder rotating around a fixed counterattack with blades. The cutting cylinder and counterates do not contact, working contactlessly, which means. almost silently. The distances between the blades on the cylinder are very small, which allows you to mow very accurately, without missing a single blade of grass and leaving a beautiful even cut.

Trimmers for grass: for and against

The pluses include the maneuverability of a trimmer for grass. the ability to gently cut off the excess around cultivated plants, walk along the boundaries of paths, at fences and buildings, and in general where the cart will not pass. In addition, a trimmer can cut grass of any height, even to the waist, even higher (of course, we are not talking about low.power, 250-500 watts, trimmers to trim the grass near the curbs), and rather about motorcycles.

The disadvantages include, firstly, the need to hold the tool in the hands and weight. Yes, many trimmers for the grass of well.known brands are equipped with reliable and convenient systems for attaching a trimmer for grass on the body, have a lightweight design and an ergonomic handle, but still not all users are able to control with a trimmer. it’s easier to roll a cart. The second minus refers to the quality of the work: the trimmer for the grass will easily remove the bulk of the grass, but it is very difficult to achieve an even cut with a trimmer: for “English lawns”, a gas mower is more suitable with the adjustment height of the cut. Thirdly, there is no grass collector in trimmers. If you cut the grass in a low altitude, then the mowing is not a problem remaining on the ground, but if thickets, you will have to be wielded with rakes then. Fourthly, you need to work with a trimmer in a defending face and especially the eyes of a mask or in special glasses: grass flies in all directions. Some models have a protective casing, but when working with large spaces and high grass, it is useless: it will instantly clog.
