Trimmer mowing head

It is a special assembled coil with a cord inside.

The trimmer head is classified according to the line feed method:

  • Manual. In this case, the name speaks for itself, that is, the line is fed mechanically. To make the cord even longer, you must stop the trimmer and manually pull the ends.
  • Semi-automatic. If you want to replace the cord, the trimmer head needs to touch the ground. At the same time, a special button is pressed and the anchor mechanism opens. Further, the lengthening of the cord occurs due to the centrifugal force. The main feature is that the procedure takes place when the trimmer is on.
  • Automatic. To make the cord elongate, the engine speed is reduced. Further, when increasing them, the line is fed automatically.

From the foregoing, it follows that the manual mowing head for the trimmer is inconvenient.

How to choose the right one?

Before purchasing this equipment, you need to understand for what purpose it will be used. For a large area with a flat lawn, it is better to purchase a light model with low power. If you need to equip a summer cottage, then you need to choose a more powerful model.

Trimmer head: types and description

One of the common devices for cutting grass is the trimmer. It is very easy to operate and maintain. That is why it has become popular among the population. Its significant advantage is its low weight. Even a child can handle such equipment.

Specifications

The main technical characteristics of the trimmer are:

  • power;
  • equipment weight;
  • type of power supply (from the network or using a battery);
  • engine location (top or bottom);
  • type of cutting element;
  • rod type.

All this must be taken into account, buy this or that device.

Cutting tool

To make the cutting process easy, you need to choose the right cutting element.

What it is?

The trimmer consists of a cutting element, a bar, a motor and a handle with a control mechanism.

Classification by filling method

The trimmer head can have several ways of threading the line:

  • Quick Chargers. The new cord is wound without disassembling the coil, that is, there is no need to remove it from the device. The end of the new element is pushed into the spool and then wound a certain number of times. When a specific value is reached, the cord is cut. This type of trimmer head is available from Shindaiwa and Speed-Freed.
  • Collapsible. Here the name itself speaks for itself. To replace a new cord, you need to remove the spool from the equipment, then unwind the old line and wind a new one.

Design features

It should be noted that the trimmer cutter head contains special arrows. They allow you to rotate the coil in different directions. If it becomes necessary to wind the line in the direction of rotation of the shaft, it turns to a specific position. A large amount of wound cord can damage the equipment. The two arrows are only found on imported models. Single hand heads are currently on the market.

If, after hitting the semi-automatic head, the cord is not wound, then its previous winding was performed incorrectly. That is, after the trimmer head was installed, the user did not pull the ends of the line out of the grooves. Another unpleasant moment when mowing grass can be the sintering of the coil turns.

For various models of trimmers, a semi-automatic head is used, consisting of two parts. a body and a spool. Both elements contain springs. The second part can be performed in several versions:

  • single-section. both parts of the line are wound together;
  • two-section. each end is wound on a specific part; this type is the most effective, since the line does not get tangled and does not bake.

There is a simple and cheap way to convert a one-piece spool to a two-piece spool. This requires a sturdy plate. From it you need to cut a circle, the diameter of which should be equal to the thickness of the spool. In this case, the thickness is taken near the place where the line is wound. This circle moves freely. Next, a cut is made on the ring, put on a spool and connected with glue or tape.

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need 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.

  • Stop the mowers engine or power off the trimmer before placing the line into the spool to avoid injury from accidental starting rotation of the cutting tool.
  • 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 be aware that the thread on the shaft is left-handed. Therefore, turn the trimmer coil to the right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the clips. To remove it, you will need to sink these latches into the case, squeezing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  • Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine load and higher gas mileage.
  • Find the midpoint of the line by folding it in half. You will have a loop.
  • Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this groove.
  • Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlap and with good tension. When the winding is finished, leave free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
  • Assemble the mowing head. Be sure to insert the spring and washer (if equipped) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or lugs.
  • Put on the cover and secure it with the latches.
  • Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counter-clockwise).

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

  • Take a piece of plywood or PCB and draw a circle about 14 cm in diameter on it.
  • Cut the disc with a jigsaw or metal hacksaw.
  • Drill a hole in the center of the disc that matches the diameter of the gearbox shaft. Do not forget to put a washer on it before installing the disc on the shaft.
  • Small corners can be screwed on the edges of the disc or 1-2 holes can be made on opposite sides. They will serve for refueling the fishing line in them.
  • Several screws can be screwed into the plywood to secure the line.

This homemade mowing head is secured to the shaft with a nut. It will not work to tighten or unscrew the nut without fixing the shaft. To replace the cord, it will be enough to loosen the screws, insert a piece of line of the required length and press it again.

Also, the mowing attachment for attaching the fishing line to it can be made of metal sheet. How to do this can be understood from the following video.

The method of attachment of attachments may be different for different models. But in general terms, the design is very similar. Here is a step-by-step instruction:

  • Find the hole in the gearbox cup (it is located either on top or on the side) and align it with the hole in the shaft hub.
  • Pass a hex key or metal rod through the hole in the gearbox to prevent the shaft from turning.
  • Hold the key with one hand and unscrew the line spool with the other (usually turn clockwise).
  • Remove the coil.

Disconnect the tool from the mains before removing the line from the trimmer. If you have a lawn mower, be sure to turn off the engine.

Trimmer coil device

Trimmer mowing heads come in a variety of designs, both simple and complex. The picture below shows an exploded view of the semi-automatic trimmer head from a Husqvarna (Husqvarna) lawn mower.

This type of head is present on most lawn mowers and trimmers such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The device of the mowing head is quite simple. It includes the following details:

  • mowing head base;
  • button for semi-automatic cord feed;
  • bobbin (spool) into which the line is tucked;
  • spring;
  • eyes. through them the line comes out;
  • trimmer head cover;
  • line (cord).

There are also simpler trim heads shown in the following photo.

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

Replacing the coil on the trimmer

The trimmer, whether petrol or electric, is the only solution for mowing grass in hard-to-reach places that a wheeled lawnmower cannot handle. As a cutting tool in trimmers, metal knives or special fishing line are used, which is tucked into the trimmer coil. But, unfortunately, trimmer heads become unusable over time during operation. Some malfunctions can be eliminated by hand, and some require a complete replacement of the mowing head.

Major coil malfunctions

Trimmer users and lawn mowers often face a problem with the semi-automatic mowing head. Coil malfunctions can be as follows:

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

Method 2. two segments

Two coiled line lengths

fundamentally no different from the method The only difference is two wound pieces of fishing line, instead of one.

The end of each segment is folded

The end of each segment is folded.

Two special fixing sockets

There are two special fixing sockets on the coil (see picture above).

We begin to reel the fishing line

They cling to it with a hook formed earlier on the fishing line, and begin to wind the fishing line.

Winding is carried out in a special order

The winding must be carried out in the following order: first the lower line, i.e. the one that is closer to the fixing holes at the bottom of the coil, and only then the top one, i.e. the one that will overlap the bottom section.

The bottom line is reeling

The tips are cut into the holes in the trimmer spool body. They are pulled up until they click, which means that the line has come out of the latches.

The tips are threaded into the holes in the trimmer spool body

The coil is fastened into the body. The line in the spool has been replaced.

Trimmer head replacement tool.

To replace, remove the cutting head from the tool, we need an asterisk nozzle, usually supplied in the kit, or a flat wide screwdriver. Using a hexagon instead of an asterisk will not work, the nozzle slips, licking the edges of the asterisk on the screw.

How to replace, remove BlackDecker GL716 trimmer head

No matter how well the electric trimmer we purchased works in a summer cottage or a country house. sooner or later the time will come when we need to remove the trimmer head for replacement or prevention. I will make a reservation right away that you do not need to completely remove the trimmer head to replace the fishing line. As part of this article, I will tell you how to completely remove or replace the cutting head using the example of the BlackDecker GL716 electric trimmer.

How to remove the trimmer mowing head.

The design and fastening of the working part of the electric scooter differ significantly from different manufacturers. But given that there are many copies of less well-known brands in our markets, the described procedure may be suitable for owners of other portable garden equipment for lawn and grass care.

How to remove the head on the trimmer BlackDecker GL716.

The trimmer has an overhead engine and a curved boom. For the convenience of work, we turn it down with the engine or lay it horizontally. We disassemble the mowing head. To do this, simultaneously press on the side latches and remove the top cover. Disconnecting the line spool.

A slightly recessed dark screw is visible in the middle of the head body. We fix the head body with one hand and use an asterisk nozzle to unscrew the screw counterclockwise. If there is no sprocket at hand, you can do this with a wide flat screwdriver.

Now, pull the trimmer head towards you to remove it. If it sour and sits firmly in place, then add light swaying movements to the efforts, periodically changing the places of their application. Do not use force or shock. The case is plastic and it is easy enough to damage it.

Trimmer head: types and description

One of the common devices for cutting grass is the trimmer. It is very easy to operate and maintain. That is why it has become popular among the population. Its significant advantage is its low weight. Even a child can handle such equipment.

Trimmer mowing head

It is a special assembled coil with a cord inside. Its dimensions can be varied. On the inside of the spool, a 15-meter cord should be wound. Its ends are pulled out a certain distance to do the job. When meeting with a solid object, it is destroyed. The trimmer mowing head is available in various designs. It all depends on the type of device. They differ not only in design, but also in the way they are connected. There is also a universal trimmer head that is suitable for different equipment. This became possible due to special adapters.

The trimmer head is classified according to the line feed method:

  • Manual. In this case, the name speaks for itself, that is, the line is fed mechanically. To make the cord even longer, you must stop the trimmer and manually pull the ends.
  • Semi-automatic. If you want to replace the cord, the trimmer head needs to touch the ground. At the same time, a special button is pressed and the anchor mechanism opens. Further, the lengthening of the cord occurs due to the centrifugal force. The main feature is that the procedure takes place when the trimmer is on.
  • Automatic. To make the cord elongate, the engine speed is reduced. Further, when increasing them, the line is fed automatically.

How to choose the right one?

Before purchasing this equipment, you need to understand for what purpose it will be used. For a large area with a flat lawn, it is better to purchase a light model with low power. If you need to equip a summer cottage, then you need to choose a more powerful model.

Specifications

The main technical characteristics of the trimmer are:

  • power;
  • equipment weight;
  • type of power supply (from the network or using a battery);
  • engine location (top or bottom);
  • type of cutting element;
  • rod type.

All this must be taken into account, buy this or that device.

Cutting tool

To make the cutting process easy, you need to choose the right cutting element.

An ordinary trimmer line or knife is often used in its role. When choosing one of the species, it is worth evaluating the type of vegetation. In accordance with these data, a cord is selected, a knife of a certain shape. An important element is the trimmer head. We will consider its varieties below.

What it is?

The trimmer consists of a cutting element, a bar, a motor and a handle with a control mechanism. It is designed for mowing grass in garden areas and for creating the perfect lawn. Thanks to its compactness, the device does the necessary work in places where the lawnmower cannot reach. In addition to grass, the trimmer is designed for mowing tree branches and bushes, as well as creating flower beds. Such equipment is not always used for the lawn, since the length of the grass will have different heights.

Classification by filling method

The trimmer head can have several ways of threading the line:

  • Quick Chargers. The new cord is wound without disassembling the coil, that is, there is no need to remove it from the device. The end of the new element is pushed into the spool and then wound a certain number of times. When a specific value is reached, the cord is cut. Head with line for trimmer this type is produced by Shindaiwa and Speed-Freed.
  • Collapsible. Here the name itself speaks for itself. To replace a new cord, you must take off spool from the equipment, then unwind the old line and wind a new one.

Popular electrocos models

One of the most popular options is the Stihl FSE-81 electric scythe. This is one of the most powerful lawn trimmers available. This machine includes the AutoCut C5-2 mower headset, designed for working in small areas. It is convenient to mow with it next to flower beds, borders. She cleans well the area around shrubs and trees, as well as carefully works the paths.

This braid has a number of advantages in that it electronically adjusts the rpm. The design allows you to keep trees from damage. The circular handle allows you to perform high-quality work, maneuver and mow in hard-to-reach places. Easy to transport.

There are other options that have proven themselves in gardening.

Line does not lengthen automatically

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

Option 1. a bite has occurred, i.e. clamping the cord between turns. This problem usually occurs if the user has been winding the line on the reel unevenly, with intersecting turns, or winding 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, as a result of which inter-turn clamping of the fishing line is possible. To fix the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, in even turns with good tension.

Option 2. too short ends protrude from the head. The line may not come out when hitting the ground if the ends sticking out of the head are not long enough (short). In this case, the centrifugal force is not enough to stretch the line. Therefore, it is required to stop the unit (turn off the engine or disconnect the trimmer from the mains) and pull out the line manually, after pressing the button.

Option 3. the line is brazed inside the mowing head. This causes the coil to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during prolonged operation of the unit, hitting the line against hard objects.

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

How to remove the spool from the Stihl trimmer

Stihl’s garden equipment has long established itself on the agricultural market. Electric trimmers of this company are distinguished by quality, reliability, stable operation even under high load. The Stihl electric kos lineup is easy to use and easy to maintain. This gives an excellent opportunity to use the technique even for a beginner.

The cord lengthens spontaneously

There are times when the trimmer user notices a very fast line flow. However, he never hit the ground with a button to lengthen the line. The reason for the fact that the line spontaneously lengthens, being cut on 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 the 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 know about its existence.

Also, the line can be lengthened without using a button if the spring is loose. If checking the spring has confirmed this fact, then several washers must be placed under it in order to enhance its clamping properties.

Different types of trim heads. their pros and cons.

In my work, I used three types of trimmer heads.

I will dwell on their description, pros and cons.

First. with manual line pulling.

I can’t say anything bad about her. The disadvantages of this head include the following moment: to pull out the line, you need to manually unscrew the lamb by 2 turns and then tighten it. If you unscrew it by 3. 4 turns, then the head clamping mechanism may “spill”. Collecting it is not a problem, but it all takes time.

The trimmer head with center button is commendable. Highly recommend. The process of pulling the line is reduced to pressing a button and pulling the “whiskers” of the line. Fast and efficient. The disadvantages include the fact that sometimes the latches “give away” and the head “self-disassembles”. I have had it like this two times and all because I did not fully click the latches. I think that over time the clamps will loosen and “self-disassembly” of the head will occur more often. When mowing grass and once hit the ground with a button and my “mustache” got out of the head by itself. I can’t say it’s a plus or a minus. So you can erase the button and on the other hand you do not need to stop to manually pull the line.

The third trimmer head is, by and large, my “headache”.

Bought for her price. twice as high as the rest of the heads. And received. twice as many problems. In my opinion, merits. not.

Problems: the head is disassembled according to the instructions by hand. In fact, you have to use a “knock-out” nail or pin. The line has to be cut into 2 pieces, and not wound, bending in half. When screwing onto the mower, it is necessary to use a locking pin and a wrench, which is inconvenient. Since when tightening other heads, only the locking pin is used. The trimmer head itself is heavy, the longer and the usable line length is reduced. Because of this, the line bends more easily and mows worse. This statement is that it mows worse. purely subjective opinion. I don’t like the head, that’s why it mows “worse” for me. Really. there are no such strong differences, but still it is inconvenient to climb up somewhere because of its size. The biggest problem. it is that she chops the line near the exit from the head. Therefore, in order to get the line, you need to completely dismantle the head from the mower. And this is, in total, from 5 to 10 minutes. Other heads can be disassembled without removing them from the mower.

The reason for cutting the line is that the hole is plastic, not metal as on other heads. As a result, for one line break in other heads there are 10 breaks on this head, and if we talk about the sections, then the first heads tear the line once in 3.4 sections, and this head. 3-5 times in one section.

The sharp edge cuts the line So the line is not cut on the edge Bumped into a branch

Typical for this head “. your mother” and “e.” with its subsequent complete disassembly

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need 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.

  • Stop the mowers engine or power off the trimmer before placing the line into the spool to avoid injury from accidental starting rotation of the cutting tool.
  • 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 be aware that the thread on the shaft is left-handed. Therefore, turn the trimmer coil to the right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the clips. To remove it, you will need to sink these latches into the case, squeezing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  • Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine load and higher gas mileage.
  • Find the midpoint of the line by folding it in half. You will have a loop.
  • Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this groove.
  • Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlap and with good tension. When the winding is finished, leave free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
  • Assemble the mowing head. Be sure to insert the spring and washer (if equipped) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or lugs.
  • Put on the cover and secure it with the latches.
  • Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counter-clockwise).

Option 3. the line is brazed inside the mowing head. This causes the coil to lock and not spin when the button is pressed. Basically, this happens for several reasons: poor quality of the cord, overheating of the coil during prolonged operation of the unit, hitting the line against hard objects.

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

How to remove the spool and replace the line

Trimmer owners, mostly beginners, find themselves in confusion, bordering on panic, when they need 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.

  • Stop the mowers engine or power off the trimmer before placing the line into the spool to avoid injury from accidental starting rotation of the cutting tool.
  • 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 be aware that the thread on the shaft is left-handed. Therefore, turn the trimmer coil to the right, that is, clockwise.
  • Disassemble the mowing head. Most often, the head cover is attached to the clips. To remove it, you will need to sink these latches into the case, squeezing the edges of the cover. If your trimmer has a semi-automatic mowing head with a button on the bottom, then the disassembly of the attachment should be done carefully, since you can lose the spring, which sometimes flies out when the cover is removed.
  • Cut off the required amount of line. Usually its length is 5 meters. Use a cord of the same diameter as indicated in the instructions for the tool. It is not recommended to exceed the maximum line diameter as this will result in increased engine load and higher gas mileage.
  • Find the midpoint of the line by folding it in half. You will have a loop.
  • Special grooves are cut inside the coil (there may be holes). Insert a loop of line into this groove.
  • Wind the line around the spool by turning it counterclockwise. It is necessary to fill in the cord as evenly as possible, the turns should lie down without overlap and with good tension. When the winding is finished, leave free ends of the line about 20 cm long and fix them in the grooves on the sides of the reel.
  • Assemble the mowing head. Be sure to insert the spring and washer (if equipped) before final assembly of the accessory. Place the spool in the body and thread the ends of the cord through the holes or lugs.
  • Put on the cover and secure it with the latches.
  • Screw the adapter back onto the gearbox shaft, also securing it with a screwdriver. You will need to twist the trimmer coil to the left (counter-clockwise).

Trimmer coil device

Trimmer mowing heads come in a variety of designs, both simple and complex. The picture below shows an exploded view of the semi-automatic trimmer head from a Husqvarna (Husqvarna) lawn mower.

This type of head is present on most lawn mowers and trimmers such as Stihl (Stihl), Patriot (Patriot), Champion (Champion), Bosch (Bosch), Huter (Huter) and others. The device of the mowing head is quite simple. It includes the following details:

  • mowing head base;
  • button for semi-automatic cord feed;
  • bobbin (spool) into which the line is tucked;
  • spring;
  • eyes. through them the line comes out;
  • trimmer head cover;
  • line (cord).

There are also simpler trim heads shown in the following photo.

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

DIY trimmer coil repair

The trimmer, whether petrol or electric, is the only solution for mowing grass in hard-to-reach places that a wheeled lawnmower cannot handle. As a cutting tool in trimmers, metal knives or special fishing line are used, which is tucked into the trimmer coil. But, unfortunately, trimmer heads become unusable over time during operation. Some malfunctions can be eliminated by hand, and some require a complete replacement of the mowing head.

Major coil malfunctions

Trimmer users and lawn mowers often face a problem with the semi-automatic mowing head. Coil malfunctions can be as follows:

remove, trimmer, head, champion
  • the line does not lengthen automatically;
  • the cord spontaneously comes out of the reel.

The cord lengthens spontaneously

There are times when the trimmer user notices a very fast line flow. However, he never hit the ground with a button to lengthen the line. The reason for the fact that the line spontaneously lengthens, being cut on 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 the 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 know about its existence.

Also, the line can be lengthened without using a button if the spring is loose. If checking the spring has confirmed this fact, then several washers must be placed under it in order to enhance its clamping properties.

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

  • Take a piece of plywood or PCB and draw a circle about 14 cm in diameter on it.
  • Cut the disc with a jigsaw or metal hacksaw.
  • Drill a hole in the center of the disc that matches the diameter of the gearbox shaft. Do not forget to put a washer on it before installing the disc on the shaft.
  • Small corners can be screwed on the edges of the disc or 1-2 holes can be made on opposite sides. They will serve for refueling the fishing line in them.
  • Several screws can be screwed into the plywood to secure the line.

This homemade mowing head is secured to the shaft with a nut. It will not work to tighten or unscrew the nut without fixing the shaft. To replace the cord, it will be enough to loosen the screws, insert a piece of line of the required length and press it again.

Also, the mowing attachment for attaching the fishing line to it can be made of metal sheet. How to do this can be understood from the following video.
