How to change a fishing line for a trimmer in a trimmer

Trimmer for grass is the most common unit used to cut grass and cut small shrubs. This device is distinguished by its simplicity in maintenance, simple management during operation, and even women cope with it even a small weight. It is no secret that for the high.quality performance of herbal mowing work, the correct selection of a cutting tool is required. As the latter in trimmers, special cutting nozzles (wheels, knives) or trimmer heads with fishing line inside are used. Nozzles and a fishing line for a trimmer are a consumable tool, but if the knives can be sharpened, then when spending the fishing line you need to replace it. In this article, we will tell you in the most detail how to correctly replace the fishing line for the trimmer.

A mowing head for grass is a cylindrical case in which a coil (bobbin) is inserted with a fishing line in it (cord). This design can be installed both on gasoline and electric trimmer. The heads differ in the method of refueling and supplying the cord and there are 3 types.

  • Automatic. The cord is supplied after the user reduces engine speed. Although the automatic supply of the fishing line is convenient if large volumes of work are performed, such rods have one drawback. a large thread consumption.
  • Semi.automatic. Using this type of head does not require complicated manipulations from the user. The principle of their operation is arranged so that the cord is automatically lengthened at a time when the device works at full speed. It is enough to slightly hit the trimmer’s head for the grass on the ground (this removes the cord lock), and the fishing line for the trimmer, due to the centrifugal force, moves out of the bobbin, after which it is cut to the desired length with a knife located on a protective casing.
  • Manual. For lengthening the cord, the device is required, after which the fishing line for the trimmer is handed out manually.

Based on the above, semi.automatic bobbins are the most optimal option. It should also be borne in mind that the coils for a trimmer for grass are one.built (used only to trim the grass) and two.string, which are used to mow high grass and small, with thin stems of shrubs.

How to remove and disassemble a coil

Before proceeding to the process of replacing the cord, users of trimmers need to remove and disassemble the coil. Consider how to do it.

The mowing head of a trimmer for grass consists of several parts: a casing, springs (not in all models), bobbins with a cord and cover.

Attention! Before proceeding with any actions to maintain an electric unit, it must be disconnected from the network.

Trimmers most often use 2 options for fastening a mowing head.


To remove the head of the trimmer for the grass, it will require its complete disassembly.

  • To remove the lid covering the inside of the head, it is necessary to press on the latch (latches) located on its two sides.
  • Removing the lid, you will see the spool that must be removed from the body. In some coils, a spring is installed under the bobbin, which must be carefully pulled out so as not to lose it in the grass.
  • Removing the bobbin, in the center of the case you will see a screw with a slot under a cross.shaped or flat screwdriver. It is possible that there may be a bolt under the hexagon or nozzle “Asterisk”.
  • Using a screwdriver, choosing the necessary bat (nozzle), you need to unscrew the bolt (counterclockwise).
  • After extracting the fasteners, take up the part of the part and, shaking it in different directions, remove the gearbox from the shaft.


In this version, the head is twisted onto the gear shaft. To remove it, you need to fix this shaft. To do this, in such trimmers, for example, in the Huter and Champion devices, a hole is provided through which you can insert either a thin screwdriver or a metal rod.

So, to remove the bobbin, take 2 simple steps.

  • Insert the screwdriver into the hole and stall the shaft.
  • Take the head of the head and start twist it clockwise. It should be twisted in this direction for the reason that the thread cut on the shaft is left.

Types of heads for trimmers

A trimmer is a tool that is used to combat vegetation in a summer cottage or household territory. Grassing and hay harvesting for cattle implies the use of benzo or motorcycle. The heads of different types are installed on trimmers for the grass, through which the grass and other vegetation occurs.

The heads are classified into three main types that differ not only in design, but even in price, the method of operation and service life. Consider all types of heads for trimmers, as well as their technical features.

Manual or mechanical coils their purpose and application

The first trimmers for grass were produced with manual types of coils that have a primitive design. They consist of a plastic or metal disk in which there are holes for fixing the fishing line. The holes have the corresponding size, which allows the cord (fishing line for a trimmer) of a certain diameter. However, this is not the only drawback of equipment, since another minus is the need for frequent fishing line refueling. Below is a variant of the simplest coil with a fishing line for a trimmer for grass.

Following the simplest coils, mechanical head heads appeared, inside which a bob is installed with a fishing rod. Such devices are excluded deficiency of the fast consumption of the cord, however, to serve a new fishing line, you should interrupt the work on the injection of grass. To supply the cord, the head is equipped with a manual regulator, through which the fishing line stretches. Today, the manual type models are rarely used, which is associated with their great drawback. the need to interrupt the work and drown out the engine in order to lengthen the cord.

What is a trimmer for grass

Under the trimmer suggest motorcycles or electrocos. This is practically one of the variety of lawn mowers (manual mower) that are created for mowing the grass. This is a modern braid braid. At first, they were developed to carry out agricultural work, but the main use of trimmers was specifically the mowing of lawns. For the first time, the thought to make a trimmer for the grass occurred to the South American businessman J. Bollas. Passing by car through an automatic car wash, he saw that the principle of spinning brushes can be used for beveling agricultural crops.

After that, he collected a simple trimmer for grass from a tin can (as a coil) and a fishing line, reached into the holes drilled in it. He installed the resulting design on a pole, on which a moped engine was previously mounted for earlier. The device is a mowing not only wheat, and grass. The device of the coil of the trimmer for the grass and it leaves the coil. a fishing line for a trimmer does not why stalls. Realizing that on the sale of braids for the grass he will earn huge funds, the businessman improved his product and gave him the title of “Excellent weeds”. A feature of the invention was the possibility of a bevel of grass around the trees. the forest perfectly cut off the grass, but did not injure the bark.

The main purpose of such a tool was the bevel of grass in small areas in places where traditional wheeled technique cannot be applied:

  • in the presence of a huge number of shrubs;
  • in gardens with a huge number of trees;
  • near fences and fences;
  • If the site has an uneven relief.

All trimmers for grass have a bar in their own composition. the main constructive element. A gasoline or electronic engine is attached to the rod from the 1st end, and a coil with a fishing line is put on the other-the main working element. With all this, the type of transmission can be at least any. it is limited only by the ability of the manufacturer and commercial parameters.

How to adjust the carburetor

The module adjustment is carried out by the manufacturer. During the operation of the device, after repairing or cleaning the module, it becomes necessary to adjust the carburetor.

60-80’s Hollywood Actresses and Their Shocking Look In 2021

Carburetor setup does not require replacement of spare parts. Debugging is done with the help of 3 screws that are available in the design:

  • L. controls the supply of fuel at low speeds;
  • H. controls the fuel consumption and temperature, and is also responsible for supplying gasoline at high speeds;
  • T. is responsible for the idle engine.

Adjustment of the carburetor of the trimmer for grass is carried out after the engine warms up. For this, 10 minutes of operation of the device at idle will be enough. The rotation of the mowing head at idle allows you to start directly to debug the screw t. It is turned counterclockwise to the cessation of rotation. Then the screw h is scrolled to the right and left to find the position in which the idle speed will be maximum. The screw is turned off on ¼ full turnover counterclockwise from the found point, this will be the working position.

According to the same technique, the screw l. After repairing the carburetor, the module is necessarily tuned so that the device works correctly.


In order to change the fishing line for the trimmer, it is necessary to extract the old one (if it was).

The coil is part of the design of the trimmer for the grass, which is located inside the head of the motorcosa, drum or bobbin. Depending on the manufacturers of the head can be different. But this article discusses only Patriot, although their mechanism is used by many other companies.

Now you need to understand how to properly remove the head from a trimmer for grass and how to get a drum out of it.

Instructions on how to promote a hand head on a trimmer is described below.

  • First of all, you need to clean the head of dirt and adhering grass if it is contaminated. To do this, you need to raise a motorcycle head up and, holding the casing, remove a special protective cover dressed on the drum.
  • The next step needs to remove the reel from the drum. The coil is easily removed even with one hand, because it is not fixed inside the drum.
  • The drum itself is fixed in the trimmer with a bolt. This bolt must be unscrewed, after which you can easily pull out the drum. To do this carefully, you should support the drum with a coil, while twist the screw counterclockwise.
  • Now you can pull the coil out. As mentioned above, it is not fixed in anything except a hook with a metal shaft, so it does not need to be torn off with force. Neatly, in a circular movement you should pull the coil from the drum.
  • Now it remains to extract an old fishing line for a trimmer and follow the following instructions.

Installation of the coil and drum in its former place is performed according to the opposite algorithm.

Before the process of refueling the fishing line, it is worth making sure that the thread suitable for a trimmer was bought. In the case when the thread is not suitable, the fuel or energy consumption increases, as well as the load on the motor motor.

In order to replace the thread itself directly, you need to prepare a piece of thread of the required size. Most often, this requires about 4 m fishing line. A specific figure will depend on the parameters of the thread, for example, its thickness, as well as on the parameters of the coil itself. If it is not possible to accurately determine the length, it can be done as follows: insert and wind the thread to such a state that the coil is completely charged (the level of the fishing line will be compared with protrusions in the sides of the coil). It is necessary to ensure that the fishing line for the trimmer sits in the coil exactly.

Do not forget that the thick thread will be shorter than thin.

The instructions for refueling the fishing line in the coil is described below.

  • The prepared thread must be taken and turned in half. It should be ensured that one edge is longer than the other by 0.1-0.15 m.
  • Now you need to take the ends in different hands. The one that is smaller must be pulled to more, so that it becomes 2 times shorter. When bending, the indentation should be maintained at 0.15m.
  • Find the slot inside the coil partition. Carefully prick the loop that turned out earlier in this slot.
  • To continue work, it is necessary to determine the direction of winding the thread in the coil. To do this, just examine the coil. there should be an arrow on it.
  • If the gunner could not be found, it is quite possible that there is a written designation. An example is given in the photo below. It is necessary to inspect the head of the coil. It has a direction indicator. However, this is the direction of the coil movement. To get the direction of winding, you need to wind in the opposite direction.
  • Now you need to season the reel with a fishing line. It is worth noting that there are special guide grooves inside the coil. When wrapping a thread, you need to follow these grooves, otherwise you can damage a trimmer for grass. At this stage, you need to charge the coil very carefully.
  • When the user winds up almost the entire thread, you should take the short end (do not forget about the protrusion of 0.15m) and stretch it into the hole located in the coil wall. Now you need to repeat this action similarly with another end (on the other hand).
  • Put the coil itself in the coil head, before that, extinguishing a fishing line for a trimmer through the holes inside the drum.
  • Now is the time to return the drum to your place. After that, you need to take with both hands by the ends of the fishing line and pull them to the sides. Then you need to put the lid in place (here you can safely make efforts until a characteristic click is heard).
  • Remained to perform “cosmetic work”. You need to see if the thread has come out too long. You can start a trimmer for the grass and check in practice whether everything is comfortable. If the thread came out a little long, you can cut it with scissors.

How the head with a fishing line on a motorcycle works why you need to know the principle of work

Depending on the manufacturer, the heads differ structurally not only externally, but also inside. Most drums have a clamping spring inside (semi.automatic and automatic). The instruction is presented above how to disassemble the head of the trimmer for grass without a spring, t.e. on a manual.type head. The principle of dismantling a semi.automatic head with a spring inside almost identical above described instructions.

The principle of operation of the semi.automatic coil of the trimmer for the grass is as follows:

  • Inside the head is a coil, which is planted on slots that prevent its free movement
  • The coil is affected by a spring that presses it to the slots located in the design of the lid
  • A fishing line for a trimmer is wound for a tip, the length of which depends on the tool itself. Usually this length is from 1 to 4 meters
  • During the work, if it is necessary to increase the length of the fishing line, the protruding part of the drum occurs, through which it comes out of the hook with the slots. In this case, the fishing line for the trimmer is wound from the drum, increasing in the length
  • Having released the required amount of fishing line, you should release the pressing, and continue to perform work on the injection of the grass

The advantage of the tool with a fishing line is that this consumable does not require sharpening compared to metal disks. In addition, if a stone or tree comes across the way, then the fishing line for a trimmer simply breaks off, without having a negative effect on the gearbox and the engine engine, as is the case with metal cutting discs.

Knowing the design and device of the types of mowing or trimmer heads, it is necessary to proceed to the consideration of the process of refueling the fishing line into the coil of the trimmer for the grass. After all, it is precisely this moment that most owners of the Special Instruction causes difficulties.

How to wind a fishing line for a trimmer?

The winding method depends on the type of coil, however, in any case, you first need to choose the right cutting material correctly. On the packaging or in the instructions for each model, the diameter and shape of the fishing line is indicated, it is very important to use just such material, otherwise there will be problems with winding.

The spider is collapsible

Here is the procedure that needs to be performed in order to change the fishing line for the trimmer:

  • fix the gearbox of the trimmer for the grass to exclude the rotation of the head;
  • Weaken the bolt that holds the fishing line for the trimmer, rotating it with the help of the mesture key counterclockwise;
  • pull the remains of the string;
  • Cut 2 pieces of a new fishing line of the required diameter, the length of each segment is 20–40 cm;
  • Insert both segments into the holes of the coil so that they are separated in half;
  • Twist the fixing bolt.

Spider Negrivable and Wind

Here’s how it is necessary to act in order to correctly wind the fishing line for the trimmer to the coil of the lawn mower:

  • With your fingers, grab a fishing line for a trimmer passing along the inside of the coil and pull it out of the head;
  • Cut a new string into pieces of the desired length;
  • Insert the segment into the hole a little more than half the length, then wrap and remove it through the next hole;
  • If the fishing line for the trimmer is thick, then you can make pieces of smaller length and, after inserting into the coil, wrap the edge of the string so that it enters the next hole by 0.5–1 cm.

Semi.automatic (collapsible)

Here is the procedure that needs to be performed in order to change the fishing line for the trimmer:

  • Squeeze the latches to separate the upper part from the base;
  • Remove the upper part and pull out the spool without losing the spring;
  • Remove the remains of the old fishing line;
  • Cut a piece of string 2-3 m long;
  • Fold the segment by half;
  • Insert the curved middle of the segment into the sloping of the spool;
  • wind the string in accordance with the direction indicators on the rogue or upper cover;
  • fix the fishing line for the trimmer on both sides in the slopes of the spray;
  • Insert the rogue and the spring, passing both ends of the string through the corresponding holes;
  • Install in place and fix the top cover;
  • Pull alternately for each of the edges of the fishing line to remove the string from the latch.

Automatic (indiscriminate)

Here is the procedure that must be performed:

  • Press the shock button and pull the remaining fishing line from the head;
  • Transfer the button to the position of replacing the string, for which combine the tags on it and the upper cover;
  • Cut a piece of string 2-3 m long, insert this segment into the reel;
  • wind the string, rotating the button, the direction of rotation is indicated on the body.

String. consumable for a trimmer for grass, so it often has to be changed. The improper implementation of this operation not only greatly complicates the process, but also often increases the consumption of the material.

over, for each type of trimmer head there is its own procedure that provides the best result. Now you know how to correctly change the fishing line for a trimmer for a knife for a lawn mower, put a disk on the device and you can quickly perform this operation on any coil.


In this section, we will talk about how to make 4 trimmer heads of various types:

Analogue of the collapsible “spider

The original of this coil can be bought for Aliexpress, and it will be required to make it:

You Won’t believe What People Found on These Beaches

  • an aluminum bar with a diameter of 45–55 mm, if there is no bar, 4 cm thick leaf aluminum is suitable;
  • a screw or bolt M4. m6 10-15 mm long with the same direction of thread as the shaft of a trimmer for grass;
  • turning or turning and milling machine;
  • drilling machine;
  • corner grinder;
  • vise;
  • set of drills;
  • set of taps and dies.
  • Cut the corner grinder from the bar 2 pieces, one 20 mm thick, a second thick 30 mm. If there is no bar, cut 2 circles with a diameter of 35–45 mm from sheet.
  • If you use circles from the plate, turn them over to a diameter of 30–35 mm with a lathe.
  • Turn the long piece so that 2 staged one on another cylinder is obtained. the diameter of the lower cylinder is the original, the length is 25 mm, the diameter of the upper cylinder is 20–25 mm, that is, 10 mm less than that of the lower, the length is 5 mm of 5 mm.
  • On a short cylinder, cut the thread with any step, the main thing is that it is the same direction as the thread on the shaft.
  • In the middle of the large cylinder of this part, drill 2 holes at an angle of 90 degrees, the diameter of each 3-4 mm, then tear them with a drill with a diameter of 6–8 mm.
  • In the end of this part from the side of the large cylinder, drill a hole for the thread of a bolt or screw, then cut the thread.
  • In a short segment with a cutter, drill a cavity to get a bowl with the thickness of the walls under the thread corresponding to the thread on the short cylinder of the long part, the depth of the cavity is 6–8 mm.
  • Cut the corresponding thread into the cavity.
  • Measure the diameter of the shaft of the trimmer for the grass and the step of its thread. In the vast majority of cases, in devices with a direct bar on the shaft, the left thread M10x1 or M10x1,25, in models with a curved rive, the right M8x1,25, but exceptions are possible.
  • In the bottom of the bowl, drill a hole under the thread on the shaft of a trimmer for the grass, then cut it.
  • Cut the bolt along the length so that, being protected, he presses, but does not give the fishing line for the trimmer. If you plan to use a fishing line for a trimmer of different diameters, then under each of them make your bolt.
  • Come on the bottom end of the bolt so that there are no sharp faces on it.

From the flywheel of the old Bobin tape recorder

In the mechanism of domestic and foreign bobbin tape recorders, a flywheel from an aluminum alloy with a diameter of 80–95 mm was used.

To turn it into a trimmer head, you will need:

  • Drill a hole strictly or a turning machine in the center of the flywheel, a hole, the diameter of which is 0.5 mm larger than the external diameter of the shaft thread. The lathe is preferable, because after it you can not balance the part.
  • Dare off all protruding elements with a bourgeois.
  • Drill drill in the end of 6 holes with a diameter of 2–4 mm from each other, then burn their edges from the inside of the flywheel with a bourgeon.
  • Put on the finished product on a bar of such a diameter that it spins on it, but does not hang out. Several times the flywheel is strongly circling, noting the place of its stop, if it always stops in different places, then the balance is perfect, if often stops in one place, then slightly growing metal from the outer surface with a bourgeois, inject it.
  • Cut 3 pieces of fishing line 2.1–2.3 times more than necessary, then tie a knot in the middle of each piece.
  • Insert each line of fishing line into 2 neighboring holes from the inside.
  • Put the coil on the trimmer for the grass, lay the standard washer on top so that it blocks the nodules, then fix it with a nut, tightening it a little stronger.
  • If necessary, cut the fishing line for the trimmer to the required length.

From plumbing PVC plugs

Such a reel is suitable only for a soft thin (up to two mm) fishing line and mowing, low low grass.

To make it, you will need:

  • Strictly in the center of the plug, drill a hole, the diameter of which is equal to the diameter of the external thread on the shaft of the trimmer for the grass.
  • In the side wall, drill 2–4 equivalent holes, retreating from a cover 1-2 cm, holes diameter 1.5–2.5 mm, depending on the diameter of the fishing line.
  • If necessary, cut the excess from the protruding part of the plug.
  • Cut 2-4 pieces of fishing line half longer than necessary, then at one of the ends of each segment tie a dense knot.
  • Put your head on a trimmer for the grass, then fix it with washer and nut.
  • Insert the fishing line from the inside so that the nodules remain in the plug.

Of the two nuts

You will need: to make this head:

  • nut with a skirt, on the thread corresponding to the shaft of a trimmer for grass;
  • A nut for M13 or M16 threads with any step (if the M8 thread is on the shaft, then take the m13 nut, if M10, then M16);
  • A thread with a thread and another nut corresponding to a nut with a skirt;
  • welding inverter;
  • file;
  • drill;
  • set of drills;
  • Corner grinder with reference disk.
  • Cut a piece of 5-10 cm long from the hairpin, then wind on it both small nuts so that they are directed with skirts to each other and acting together.
  • Insert this design into the drill and including it, grind the edges of the distant nut with a file so that it enters into a large nut with effort.
  • Insert a small nut into the big one, then scold them with an inverter to reliably connect.
  • Stir the seam with a corner grinder.
  • Drill a large nut above a small nut with a drill with a diameter of 2–4 mm so that the holes pass through the opposite edges. Can be drilled twice at an angle of 90 degrees, using drills with a diameter of 2 and 4 mm.
  • Cut a piece of fishing line double length and insert it into the hole so that both ends protrude evenly and in the middle, pry the screwdriver to form a small loop.
  • Wrap this home.made on the shaft of a trimmer for grass and tighten the hand, the shaft will fix the fishing line for the trimmer and will not let it fly out at any load.

Review: Head Kosil aluminum Aksayelektroprostroy. I hope it is eternal, and problems with plastic heads are forgotten.

This year, at the very beginning of the mowing season, my standard plastic head (for fishing line) on a trimmer for grass had already scattered. And it was almost new. Last season I used it very little.And when I went to buy a new one, I saw a hitherto unheard of such a device in the store. mowing head for a trimmer for grass from aluminum.

It turned out that this is an alternative to a regular plastic head with a fishing line. Only a thick wire or cable can also be charged into it. Naturally, compared with the plastic, she has an undoubted advantage. strength and durability. Almost eternal!

Quickly counted the costs in my mind. The cost of a plastic head. 250, plus a skein of fishing line 100, and this season at least two heads will leave. The cost of aluminum. 390, plus cable 4 mm two meters per 20 and this is for a certain number of seasons!

I bought without hesitation. And I want to share information about this novelty and my impressions.

The head of the head is simple as five cents. Just a metal disk with 4 holes for refueling fishing line or cable up to 4 mm in diameter, and the central hole for attaching to the trimmer.No instructions were attached to it, only what is written on the box. There are no ways of refueling a cable.But it’s not a problem. You can cling to the best of your imagination, the main thing is that at least two holes are visible at least two holes. This is the first time I did about the two ends, although it is possible with four.

The weight is not heavy. A little heavier than a standard plastic head with a fishing line.

When mounting to a mower, the cable is firmly clamped by a standard washer and nut. These are, in addition to holes, the location of which is made in such a way that the bends of the cable prevent its free movement.

By the way, according to the manufacturer, the fastening of this head is suitable for most trimmers. Just in case. The diameter of its landing hole is 25 mm (plus or minus 1, measured a rough roulette), and a tightening nut on the shaft of the gearbox of my braid. on 19. A complete washer has a sufficient thickness so that a nut that has for some reason a restriction on the depth of the twist, tightly presses the head.

Application.I use a mower for lawns around the house, with a variety of grass. from ordinary lawn to wormwood and bush. The new cable was, of course, with a tourniquet, but immediately after the start of the mowing “fluffed”. This slightly worsens the accuracy of the cut, but in general nothing special. Yes, and you can insert a fishing line for a trimmer if you work with a delicate lawn.True, in the absence of the opportunity to wrap with a margin, you will often have to remove the head from a trimmer for grass to change fishing line.

Steel cable and aluminum head speak for themselves. even harsh stems cut down. Not very afraid of stones, fences and other obstacles. It seems that it is most convenient to use in powerful mowers. from medium power and higher, in view of a more massive cable compared to the fishing line.

I am operating for about a week, having stolen the area in total, probably one third of the hectare. There are no problems with her so far. But the plastic coil during this time would probably crash into pieces)) In some cases, it is no longer required to change the head with a cable to a metal three.lobed disk for hard shoots, which simplifies the work.

The only thing. Safety measures when working with a cable should be more tough than with a fishing line. Pieces of grass, land, small pebbles, and, I suspect, pieces of the cable itself, fly apart. He is not eternal. Therefore, protective shoes, pants, gloves and glasses are required! It is also undesirable and the presence of a number of people.

= April 2019, addition = this mowing head was operated the whole last summer (2018), regular plastic “boxes” with a fishing line I no longer bought. And this summer I am going to use it. It has survived perfectly.It turned out that it was better to use not a cable, but a thick fishing line for a trimmer (up to 3 kV. mm cross.section). Two segments at 4 ends. And the cable will be very fluffed. A fishing line can also be chopped and wooden. In general, a great choice.

How to remove the coil and replace the fishing line for the trimmer

The owners of the trimmers, mainly beginners, confuse, bordering on panic, when it becomes necessary to change the cutting tool or fishing line for a trimmer in a reel. Very often, when trying to unscrew the mowing head, users simply make it unusable, not suspecting that it is unscrewed in the opposite direction. So that this does not happen, if you need to replace the tool, it is recommended to familiarize yourself with the instructions given below.

  • Before refueling the fishing line for the trimmer to the coil, drown out the engine of motorcycles or de.energize the ethletric trimmer for the grass to avoid injuries that may occur in case of accidental rotation of the cutting tool.
  • Unscrew the nozzle mounted on the gearbox shaft. To do this, the shaft must be fixed by combining holes on the puck and on the axis, and inserting a metal rod or screwdriver into them.
  • Unscrew the nozzle. You should know that the thread on the shaft is left. Therefore, to twist the coil of the trimmer for the grass should be right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the fixers. To remove it, you need to drown these latches into the case, pressing the edges of the lid. If your trimmer has a semi.automatic mowing head, which has a button from below, then disassembling the nozzle should be done carefully, since you can lose a spring that sometimes flies away when removing the cover.
  • Cut the required amount of fishing line. Usually its length is 5 meters. Use the cord of the diameter that is indicated in the instructions for the tool. It is not recommended to exceed the maximum diameter of the fishing line, since this will lead to increased load on the engine and greater consumption of gasoline.
  • Find the middle of the segment of the cord, folding it in half. You will get a loop.
  • Special grooves are cut out inside the coil (there may be holes). Insert the loop from the fishing line into this groove.
  • Wind a fishing line for a trimmer to a coil, turning it counterclockwise. You need to refuel the cord as evenly as possible, the turns should be laid without ceiling and with good tension. When the winding is finished, leave the free ends of the fishing line about 20 cm long and fix them in the grooves located on the sides of the coil.
  • Collect the braid head. Before you finally collect the nozzle, do not forget to insert a spring and washer (if it is available). Install the coil in the case, and prone the ends of the cord through the holes or eye.
  • Dress the lid and fix it with latches.
  • Screw the nozzle back to the gear shaft, also fixing it with a screwdriver. Tighten the coil of the trimmer for the grass will need to go to the left (against h. Arrows).

Is it possible to make a coil for a trimmer for the grass with your own hands

On sale there are a large number of trimmer heads (not automatic), which have a low price and good quality. But sometimes situations arise, for example, in the country, when the trimmer coil broke, and its repair is impossible, the store is far away, and you need to mow. In this case, you can quickly, literally in a few minutes, make a simple trimmer nozzle to fix the fishing line from ordinary plywood 10-12 mm thick.

  • Take a piece of plywood or textolite and draw a circle with a diameter of about 14 cm on it.
  • Cut the disk with a jigsaw or hacksaw for metal.
  • Drill a hole in the center of the disk, suitable in diameter to the gear shaft. Do not forget before installing a disk on the shaft, put a puck on it.
  • You can fasten small corners along the edges of the disk or make 1-2 holes on the opposite sides. They will serve for refueling fishing lines in them.
  • To fix the fishing line for a trimmer, you can screw several screws into the plywood.

Such a homemade mowing nozzle is fixed on the shaft with a nut. Twist or unscrew the nut without fixing the shaft will not work. To replace the cord, it will be enough to release the screws, insert a segment of the fishing line of the required length and press it again.
