How to put line on the grass trimmer spool

How to choose the right grass trimmer line

For installation on brushcutters, ordinary nylon scaffolding (cord) is used. The material can have a different thickness, which depends on the type and power of the tool. When figuring out how to thread the grass trimmer reel, it is advisable to consult the manufacturer’s instructions for the correct line values ​​for your particular model. As a rule, its thickness is:

  • for low-power electric trimmers. from 1 to 1.6 mm;
  • for electric trimmers from 0.5 kW. from 2 to 2.4 mm;
  • for gasoline devices. in the range of 2.4-3.2 mm.

When buying, it does not hurt to consider the structure of the forest. Curly is more suitable for cutting young plants, round. for coarser grass, and notched. for thin stems. On average, it will take 2–4 meters of cord to fill the reel. Winding more than the manufacturer’s recommendation can hinder the movement of the scaffold and make it difficult to pull out new ends when mowing the lawn.

How to wind the line onto the spool of the grass trimmer

If you regularly mow your lawn, sooner or later you will want to know how to wind the line around the grass trimmer. Brushcutter manufacturers do not provide such information, so equipment owners often find themselves in a difficult situation. The guaranteed production of the fishing line requires its regular replacement, otherwise it cuts the grass poorly or removes only young plants. Replacing consumables is not difficult. just watch the video or read our instructions, which will greatly facilitate the process.

How to fill the grass trimmer coil step by step

To properly rewind the line on the grass trimmer, the main thing is to follow the replacement steps and safety rules.

Unplug the electric grass trimmer before disassembling it. The trimmer head on any tool consists of a cover, a cover and a bobbin with wood. The way to remove it depends on the design of the grass braid:

  • Small devices with a spool at the bottom usually have keys on the sides of the spool. If you press them at the same time, the upper part of the spool will detach along with the thread, and the lower part will remain on the tool.
  • To wind the line around the spool of the curved-bar grass trimmer, find a special lamb on the spool. In such models, the head is dismantled by holding the spool and simultaneously rotating the wing nut against the clock hand. Once the nut is unscrewed, the entire coil can be removed.
  • If a gasoline or electric grass trimmer has the function of installing a knife, then you will need a screwdriver to disassemble it. To remove the head, find a hole under the spool, insert a screwdriver into it, and then wind the spool clockwise and remove it from the grass braid.

It is important to mention that the cord is placed on the spool, which is located inside the head. To get it, you need to disassemble the head. Traditionally, there is a special lock on its body, which, when pressed, opens access to the forest. To remove the bobbin, press the latch and, holding it with one hand, turn the head cover clockwise.

In some types of trimmers, latches are not provided, so you have to disassemble the case. When disassembling, it is important to remember in what sequence all the elements of the head were removed, so that after replacing the scaffold, assemble them in the same order, but only in the reverse order.

Brushcutter heads can vary in design, so the replacement of the line on an electric trimmer or its gasoline counterpart is carried out taking this moment into account. If the head has a dividing flange, the cord is changed as follows:

  • Measure the required amount of scaffold, fold it in half, and then fix it with a fold in a special groove. If there is no such groove, the cord will need to be cut into two halves and the ends of each of them must be attached to the holders that the manufacturer provides in the upper and lower parts of the spool between the bead.
  • Before you start winding the fishing line, you should determine in which direction the winding will be carried out. Usually the direction can be seen as an arrow on the spool.
  • The edges of the cord are inserted into the grooves between the bead and the reel is started to rotate so that the cord winds in the direction of the arrow. Both one and the other half of the line are laid in the same direction.
  • When threading the line into the spool of the grass trimmer, at the end of winding, the free edges of the line must be pulled into the holes on the spool. They are placed in a perpendicular direction to each other.

If the coil does not have a dividing edge, the wood is cut into two halves and their ends are placed in the holes that are located at the top of the coil. Wind both parts of the cord in the direction of the arrow, making sure that they do not cross. After winding, the free edges of the scaffold are laid on the sides of the bobbin, and if there are slots in it, then they are fixed.

The instructions above apply to trimmer heads with 2 antennae. There are other winding options. If you need to figure out how to tuck the line into a grass trimmer that has a single-barbed head, note that the process is similar, but the forest is not folded in half. In the presence of four antennae, four parts of the thread are used, which are placed alternately in the holes of the head.

The spool is installed in the head, the wood is taken out of the side blades and tightened. Next, the cord is tightly fixed and the lid is closed. The last step will be to install the reel on the braid and pull the fishing line. so that when trimming plants, it does not come into contact with the protective casing.

If you know how to properly wind the line around the grass trimmer, you can ensure its full and high-quality work. Timely replacement of the cord is a guarantee of an even haircut and a long service life of the tool.

engine’s type

Two types of motors are installed on the gasoline grass trimmer: two- and four-stroke. The first are cheap, powerful, but for refueling it is necessary to prepare a mixture of oil and A92 gasoline.

The second type is more expensive, but less “capricious”, they are installed on professional instruments. They are 1.5 times more economical than two-stroke analogs, they work quieter, create less exhaust gases. Fuel filling is carried out separately, the vibration level is lower than in cheaper samples.

Handle shape

Manufacturers offer 2 handle options:

  • T-shaped (in the form of a bicycle handlebar);
  • D-shaped;
  • J-shaped.

The handle in the form of the letter “T” is installed on models with automatic line rewinding. The work is carried out with 2 hands located on both sides of the bar. This position is convenient for mowing large areas of vegetation. The cut is made according to the principle of a grass braid. from one side to the other. This option does not differ in maneuverability, does not work well on difficult terrain. The bicycle handlebars can be equipped with control buttons. In household types of grass trimmer, the trigger buttons are installed on the bar.

Classic grass trimmer with reversible handle with control buttons

The petrol trimmer with a D-shaped handle is more maneuverable, it is convenient for them to mow the grass in areas with difficult terrain. In such an instrument, the hands are placed one above the other. The drawback of the handle is that it is difficult to hold, the control of such a device is more complicated.

The handle in the form of the English letter “J” is the most inconvenient, therefore it is rarely found.

petrol grass trimmer

Small mobile devices for cutting grass and young branches, consisting of a bar, a motor, a cutting part and a handle are called a trimmer.

The device without a trimmer is simple, it is easy to disassemble, if necessary

There are electric and gasoline modifications. The former do not fill with fuel, but they depend on the length of the cord. The latter work regardless of the availability of electricity, anywhere in the garden or vegetable garden.

Gasoline grass trimmers are lighter and less expensive than lawn mowers. They cope with grass and shrubs, so such mowers are used in everyday life and on an industrial scale. For convenience, the technique provides straps that are worn on the shoulder. Thus, the stress on the arms and back is reduced.

Tool feeding methods

In benzotrimmers there are 3 ways of feeding the line:

  • manual;
  • semi-automatic;
  • auto.

In the first case, the thread is pulled at the ends after stopping the tool.

In the second, wire feed starts after unlocking. To do this, you need to lightly hit the head on the ground.

In an automatic device, the mechanism is triggered independently after starting the engine. This option is convenient for performing a large amount of work. Disadvantage of the machine. it requires a long piece of thread.

Algorithm of actions

Before winding the line properly on the spool of the grass trimmer, follow these steps:

  • block the cutting shaft with a stupor;
  • remove the coil, to do this, press the button or two small latches (they are located on opposite sides of the rod);
  • remove the bobbin carefully (there is a spring inside the spool, which may be lost after removing the bobbin);

Bobbin with spring, spool free and ready to rewind new line

  • free the block from the remnants of fishing line and grass, if they got there;
  • measure the required length of the working thread and cut it off (usually this is a 6 meter long line);
  • fold the thread in half and place the middle inside the spool.

Further actions depend on the type of bobbin.

Model power

Lightweight and compact household devices for combating grass on an area of ​​less than 15 acres have a capacity of up to 1 hp. This figure is enough for a summer residence, a small lawn.

Power within 1. 3 hp. necessary to combat shrubs, thin branches. This is an indicator of industrial and universal units. They have a longer service life, weight, some models can create a high noise level.

If you need to get rid of young shoots of trees, thick branches of shrubs, lawn mowers with a capacity of more than 3 hp are used. These are heavy apparatus that require great physical effort to work with. The advantages of such mowers are a large supply of fuel, separate refueling of gasoline and oil, high productivity.

Model with a shoulder strap for easy operation

What are the coils

In gasoline devices, one- and two-section coils are installed. Another difference is that cutting is done with one tendril or two. Based on these conditions, a working thread is wound.

Disassembled lower part of the tool. the coil consists of one section

The bobbins are divided into 2 sections, the winding of the line is carried out on each level separately.

Winding process

If your coil is designed to work with only one tendril, then it’s simple. You need to unwind 2-4 m of fishing line (depending on the size of the reel), find a fixing hole for the line on the inside of the reel, insert one end of the line there and start winding the line in the direction opposite to the direction of rotation of the reel on the trimmer. On the inside of the reel, they usually indicate with an arrow in which direction to wind the line. After winding the fishing line, we leave a small piece of it unwound to expose it. We fix this piece in a special groove located on the inner part of the reel and designed so that the line does not unwind at the time of collecting the reel. If there is no such groove, then you will have to hold the fishing line with your finger to prevent it from unwinding during the further collection of the coil. Next, we take the outer part of the coil and thread the outer piece of fishing line into the existing hole, assemble and put the coil back on the grass trimmer.

If the coil is designed to work with two antennae, then do the following. On the inside of the reel, we look at how many grooves there are for winding the fishing line. There may be one or two of them. If there is only one groove, then both antennae are wound along this one groove. If there are two grooves, then each antenna is wound along its own groove. A reel with one groove should have a through hole through which the line is threaded. We unwind 2-4 m of fishing line, thread it through this hole so that it sticks out equally on each side of the fishing line. And we simultaneously wind both antennae of the fishing line in the same direction, opposite to the direction of rotation of the coil on the trimmer and coinciding with the direction indicated by the arrow on the inside of the coil. We leave a little of the fishing line unwound, fix the resulting ends in special grooves, and if they are not there, we hold them with our fingers. We pass both ends into the existing holes on the outer casing of the coil. We collect the coil and attach it to the trimmer.

If there are two grooves, fold a piece of fishing line 2-4 m long in half, insert the loop obtained at the place of the fold into the groove between the two grooves, and simultaneously wind both ends of the fishing line along its own groove. Further actions are similar to the previous option.

There are also reels in which the fishing line is threaded through a through hole on the inside. After that, the ends of the line, without winding, are threaded completely through the holes on the outer body of the reel, collect the reel and begin to rotate the button, which is usually pressed, in order to release the line during operation as it wears out. Rotate the button. the fishing line itself is wound inside. At the same time, it will not work to turn it in the “wrong” direction, since it can only rotate in one direction. If you get used to it, you can wind fishing line on such a reel without even disassembling it. you just need to combine the through hole of the inner drum with the holes on the outer body of the reel, and then thread the fishing line through them.

That’s all on this issue. Happy winding!

Method 1. how to properly wind the line or put it on a reel and choose the required length

To implement this method, you will need to first prepare a fishing line of the required length (usually up to 4 meters). It all depends on the thickness of the equipment used, as well as the design of the coil. There is an easy way to find out the amount of line you need to refuel to charge the reel. To do this, wind the rig inside the coil until it is aligned with the side protrusions. In this case, the rigging should not go beyond these extreme protrusions.

The thicker the equipment used, the shorter its length will be needed and vice versa, the thinner, the longer the segment will be needed.

The instruction on how to properly tuck the harness into the aiming of the grass trimmer or brushcutter is as follows:

  • To begin with, a piece of fishing line that was prepared to be installed in a reel must be folded in half. In this case, one edge should protrude more than the second by 10-15 cm
  • After that, take the second end from the other side, and bend it in half. Move to it so that the measured protrusion of 15 cm is preserved
  • There is a slot in the inner baffle of the coil, into which the resulting loop should be inserted. The cut in the wall is shown in the photo below.
  • Next, we figure out the direction of winding the line. If you wind the rig in the wrong direction, then it will not function correctly, and you will need to redo the work. To insert the line and wind it in the correct direction, inspect the surface of the spool. It should indicate the direction of winding (in 99% of cases, this direction is indicated). What the direction indicator on the coil looks like is shown in the photo below.
  • This arrow-shaped pointer can also have the designation, as in the example above “WIND LINE”, which means the direction of winding. If the pointer is missing on the reel, then you need to look at the head. There is a direction of its rotation on the head, and in order to properly wind the line, wind it on the drum in the opposite direction to the indication of the arrow indicator. So, if the arrow is on the tip, then you need to wind in the indicated direction, and if it is not there, then you should wind against the direction of the arrow on the surface of the head
  • Having decided on the direction of rotation, you should start winding. Each end should be guided in its own groove. If there is no separator, then the equipment must be laid in the appropriate distribution order.
  • When almost all the fishing line is wound on a reel, you will need to do the following. place a short part in the hole of the side wall of the pickup, the protrusion of which should be up to 10-15 cm, and then do the same procedure with the other end, placing it in the hole on the parallel side
  • We insert the coil into the head, first passing the ends of the fishing line into the holes of the drum
  • We put the drum in place and, by pulling the ends of the line, we disengage them from the temporary clamps in the wall of the reel. After that, you can put on the cover until the latch engages.
  • At this point, the process of how to replace the fishing line on the trimmer is completed, and if necessary, you can cut only the ends (if their length does not suit), and install the assembled drum on the tool

With how to put the drum in place, no difficulties arise. There is a second way, how to charge the mowing equipment in the brushcutter. What is the difference and how the second method of threading the line onto the reel of the brushcutter is carried out, we will find out in detail.

How does the head with a fishing line work on a brushcutter why you need to know the principle of operation

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

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

  • Inside the head there is a coil, which is fitted on the slots, which prevent its free movement.
  • A spring acts on the coil, which presses it against the splines in the cover structure
  • A fishing line is wound on the tip, the length of which depends on the tool itself. Typically this length is between 1 and 4 meters.
  • During the performance of work, if it is necessary to increase the length of the line, the protruding part of the drum is pressed, whereby it disengages from the splines. In this case, the fishing line is unwound from the drum, increasing in length
  • After releasing the required amount of fishing line, release the pressure and continue cutting the grass

The advantage of a tool with a line is that this consumable does not require sharpening, compared to metal discs. In addition, if a stone or a tree comes across on the way, the line simply breaks off, without adversely affecting the gearbox and engine of the tool, 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 go on to consider the process of threading the line into the grass trimmer reel. After all, it is this very moment that causes difficulties for most owners of special tools.

Technical properties of the cord and the choice of diameter according to the power of the grass trimmer

If you take a package of fishing line in your hands, then only two main parameters are indicated on it. these are the total length and section. There is no instruction on how to choose a line for a grass trimmer, so you have to ask a specialist. Finding a good specialist is not so easy, especially since every year not only new lines are produced, but also reels.

The first thing to decide is the diameter, thickness or section of the cord. All this is one parameter that characterizes the performance of work with trimmers, petrol cutters, brushcutters and lawn mowers. What is the section to buy for my grass trimmer? In order not to be mistaken, you should take a piece of the old cord with you and give it to the seller. Based on the segment provided by you, the seller will issue a similar section of the cord.

READ  Stihl trimmer does not develop speed stalls

This option is certainly reliable, but it cannot be called correct. Why? After all, the choice of fishing line depends not only on the head used, but also on the power of the tool used. To begin with, it is recommended to decide what diameter of line can be used on trimmers and petrol cutters, depending on their power parameters:

  • Electric grass trimmers with a power rating of up to 500 W. cords with a cross section of up to 1.6 mm are used. These tools are designed for cutting young grass in backyard areas.
  • Gasoline and electric units with power ratings from 500 to 1000 W. imply the use of cords with a thickness of 2 to 2.4 mm. Such units with consumables are used for cutting thin and thick grass, as well as weeds. In grass trimmers with a power of up to 1 kW, you can install a fishing line with a diameter of 1-1.6 mm, but it will wear out quickly
  • grass trimmers and lawn mowers with power ratings over 1 kW. allow the use of cord thickness from 2.4 to 3.3 mm. Such a fishing line can be used to cut off thick and dried stems, as well as dense thickets. If a consumable with a thickness of more than 3 mm does not cope with the task of cutting grass, then metal discs with blades, teeth and knives are used

It is interesting! Manufacturers produce trimmer line with a diameter of more than 3.3 mm, only it is used extremely rarely, and only on powerful gasoline units.

Preparing to replace the line

Before replacing the line, you need to pull out and then disassemble the head. Usually it includes a casing, a spring (on some models), a bobbin with a line, a cover. It is necessary to unplug the electric grass trimmer (or turn off the gasoline trimmer), and then proceed to remove the coil. It can be fixed in two different ways: in the first case, it is necessary to completely disassemble the head, and in the second, just remove it from the gearbox shaft, on which it is attached.

find the latches on both sides, press and remove the cover to open the internal structure of the head;

there is a bobbin under the cover, it must be carefully pulled out of the case (sometimes a spring is hidden under it, it should also be carefully removed to the side so as not to lose it);

  • after removing the spool, a fixing bolt (or screw) becomes noticeable in the center of the body, which must be unscrewed in the opposite direction to the clockwise movement;
  • after removing the fasteners, it is necessary to remove the coil from the gearbox shaft with shaking movements.

The second method involves the following actions. The spool head is put on the gearbox shaft. To disconnect it, you need to lock this shaft. Usually in braids, for example, of the “Champion” or “STIHL” brand, a hole is made for this, into which a nail, rod or screwdriver is inserted. After fixing the shaft in a stationary position, it is necessary, holding by the body, to start rotating the head clockwise, since the thread on the shaft is usually left.

Now that the head has been removed and disassembled, it is necessary to determine how thick the cord should be. You can find out the correct diameter for your grass trimmer by looking at the owner’s manual or at the bobbin itself, usually this information is indicated on it. Another way is to insert the thread into the hole from which it is fed. If the shit goes without difficulty, it can be used for work.

How to remove the spool from the grass trimmer and remove the line

Initially, remove the line from the spool of the grass trimmer before threading it into the spool. A reel or aiming device is a device that sits inside the mowing head, bobbin or drum. There are different types of heads (depending on the manufacturer), but the principle of replacing the line on the reel is the same for everyone. First of all, we will figure out how to remove the head from the tool, as well as how to get the drum and fishing line out of it.

It is interesting! The tooling can be changed directly on the tool, but if you are doing this for the first time, it is still recommended to remove the head and study the detailed winding process. After the technology has been mastered, you can perform replacement work on a trimmer, a brushcutter or a petrol cutter.

The instruction on how to unscrew the manual head on the trimmer is as follows:

  • Turn the tool upside down and, if necessary, clean it from dirt. With two fingers of one hand, grip the cover latches (on the mowing head), which are symmetrically positioned to each other. After lightly pressing them inward, remove the protective cover from the drum
  • Next, remove the line spool from the drum shaft. It is mounted on a shaft without fasteners, therefore it can be removed with one hand.
  • The main part of the drum is fixed with a screw, which must be unscrewed with a screwdriver with an appropriate tip or bit
  • To unscrew, hold the drum base with one hand, and unscrew it counterclockwise with a screwdriver with the other.
  • After that, you can proceed to dismantling. To do this, you do not need to pull it with all your strength, but slightly shaking it to the sides, slowly disengage it from the metal shaft on which the drum is seated.
  • When reinstalling, fit the head into the square slots

This process is not difficult, and as you know, there is no need to dismantle the entire head if you know how the replacement is performed. When dismantling, consider the following nuances:

  • Periodic removal of the head is recommended to prevent corrosion of the threaded connection. If you never unscrew the screw, then if necessary, it will be difficult and even impossible to do this.
  • If the screw has a four-sided bore of the head, then for unscrewing it is necessary to select a screwdriver or bits of a suitable size in order to exclude the licking of the edges on the head
  • When assembling the unit, treat the threaded seat with lubricants, for example, grease or machine oil.
  • If the edges on the screw are licked, then special clamping pliers can be used to unscrew it.
  • There are drums that do not require preliminary disassembly. To dismantle them, grab it and rotate in the opposite direction to the clockwise direction

Knowing how to disassemble the drum, you should continue to figure out how to change the grass trimmer line. The video below shows the detailed process of how to open the grass trimmer coil and disassemble it.

Instructions

In order to change the line, you need to remove the old one (if it was).

The reel is the part of the grass trimmer structure that is located inside the brush head, drum or bobbin. Heads may vary depending on the manufacturer. But this article only covers Patriot, although their mechanism is used by many other companies.

Instructions on how to unscrew the manual head on the trimmer are described below.

  • First of all, you need to clean the head from dirt and adhering grass, if it is dirty. To do this, lift the brushcutter head up and, grasping the casing, remove the special protective cover that is put on the drum.
  • The next step is to remove the spool from the drum. The reel can be easily removed even with one hand, because it is not fixed in any way 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 the spool, while unscrewing the screw counterclockwise.
  • Now you can pull the coil out. As mentioned above, it is not secured by anything, except for a hook with a metal shaft, so it does not need to be pulled out with force. Carefully, in a circular motion, pull the spool out of the drum.
  • Now it remains to remove the old fishing line and follow the following instructions.

Installing the spool and drum in their original place is performed according to the reverse algorithm.

Before threading the line, make sure you have purchased the correct thread for the grass trimmer. In the event that the thread does not fit, the fuel or energy consumption increases, as well as the load on the engine of the brushcutter.

Restring a 1 string spool on a string trimmer weed eater EASY!!

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 of line. The specific figure will depend on the parameters of the thread, for example, its thickness, as well as on the parameters of the spool itself. If you cannot accurately determine the length, you can do the following: insert and wind the thread until the coil is fully charged (the line level will be compared with the protrusions on the sides of the coil). It is necessary to ensure that the line sits evenly in the reel.

The instructions for threading the line into the spool are described below.

The prepared thread must be taken and folded in half. It should be ensured that one edge is 0.1-0.15 m longer than the other. Now you need to take the ends in different hands. The one that is smaller must be tightened to the larger one so that it becomes 2 times shorter. When bending, you should maintain an offset of 0.15m. Locate the slot inside the coil baffle. Gently thread the loop you made earlier into this slot. To continue working, it is necessary to determine the direction of winding of the thread in the bobbin. To do this, it is enough to inspect the coil. there should be an arrow on it. If it was not possible to find an arrow-pointer, then it is quite possible that there is a written designation. An example is shown in the photo below. It is necessary to inspect the coil head. There is a direction indicator on it. However, this is the direction of movement of the coil. To get the winding direction, you need to wind in the opposite direction. Now you need to load the spool with line.

It is worth noting that there are special guide grooves inside the coil. Follow these grooves when winding the thread, otherwise the grass trimmer may be damaged.

At this stage, you need to charge the coil very carefully. When the user winds almost the entire thread, take the short end (do not forget about the 0.15m protrusion) and pull it into the hole located in the wall of the reel. Now you need to repeat this action in the same way with the other end (on the other side). Place the reel itself in the head of the reel, before that threading the line through the holes inside the drum. Now is the time to put the drum back in place. After that, you need to take the ends of the line with both hands and pull them to the sides. Then you need to put the lid back on (here you can safely make efforts until a characteristic click is heard). Remained to do the “cosmetic work”. We need to see if the thread is too long. You can start the grass trimmer and check in practice if everything is comfortable. If the thread comes out a little long, you can cut it with scissors.

How to wind the line around the mowing head of a grass trimmer or brushcutter

The video shows in detail how to wind the line onto the spool of a grass trimmer or brushcutter. Refueling with mowing line.

How to catch more fish?

  • One-string. In the modification of such a grass trimmer there is only one working line. This unit is used mainly for small jobs, such as trimming the grass.
  • Two-stringed. They can be both automatic and automatic. Here the package includes two strings. Used such a grass trimmer for mowing and clearing areas.

Instructions for correctly winding the cutting thread onto the spool of the grass trimmer:

  • First of all, you need to disassemble the head. To do this, press the latch and turn the cover to the side. Next, the spool is removed.
  • Measure out the required amount of cutting thread and insert it into the slot.
  • Wind the line on both sides in the direction of the arrow.
  • Leave the ends 15 cm long uncoiled.
  • These ends fit into opposite slots.
  • Then the ends are fixed in the hole on the head.
  • After that, the spool is carefully inserted into the body, for this you need to slightly press on it.
  • If necessary, you can pull the remaining ends of the thread outward. To do this, first pull one end of the thread, and then the other so that they can easily pass through the slots on the head.
  • Now you need to collect the grooves on the body and screw the cover.
  • Then press the spool and try to twist it all the way. If you hear a click, the spool has clicked into place.
  • Next, you need to pull the free ends of the thread to the end.

Removing the coil from the grass trimmer

On small electric bottom motor trimmers (when operating near the ground), the reel usually has two buttons on the sides. Click on them and disconnect one half of the coil body from the second, which remains on the trimmer. Together with the first half, the inner part is also taken out, on which the fishing line is directly wound. When parsing, be careful: there is a spring inside that can fly out and get lost.

On electric and gasoline trimmers with a curved bar (there is still no way to put a knife on such trimmers), you need to wrap the coil body itself with one hand, and with the other hand you need to start rotating the lamb on it counterclockwise. It is he who attaches the coil to the grass trimmer bar. Having unscrewed the lamb, carefully remove the entire coil, trying not to lose the spring inside.

On electric and gasoline trimmers with a straight bar and a gear at its end (on such grass trimmers, in addition to fishing line, you can also install a knife), we look for a hole under the coil, insert, for example, a screwdriver into it, quietly rotate the coil until the screwdriver crawls even deeper and the coil will lock. Now turn the whole coil clockwise (since the thread is left-hand) and remove it from the grass trimmer. Next, we disassemble the coil. It can be assembled with latches or twisted with a lamb. If the coil is on latches, then press on the sides on the base of the latches so that they bend and release one half of the coil body from the other. We just unscrew the lamb. There may also be a third type of connection of two halves of such a coil: with it, you need to grab the lower part with one hand, and the upper part with the other, and start turning them in opposite directions.

How does the head with a fishing line work on a brushcutter why you need to know the principle of operation

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

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

  • Inside the head there is a coil, which is fitted on the slots, which prevent its free movement.
  • A spring acts on the coil, which presses it against the splines in the cover structure
  • A fishing line is wound on the tip, the length of which depends on the tool itself. Typically this length is between 1 and 4 meters.
  • During the performance of work, if it is necessary to increase the length of the line, the protruding part of the drum is pressed, whereby it disengages from the splines. In this case, the fishing line is unwound from the drum, increasing in length
  • After releasing the required amount of fishing line, release the pressure and continue cutting the grass

The advantage of a tool with a line is that this consumable does not require sharpening, compared to metal discs. In addition, if a stone or a tree comes across on the way, the line simply breaks off, without adversely affecting the gearbox and engine of the tool, 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 go on to consider the process of threading the line into the grass trimmer reel. After all, it is this very moment that causes difficulties for most owners of special tools.

Single-barb grass trimmer reel

Many owners and specialists note the ease of use and ease of refueling the bobbin with one mustache. Depending on the manufacturer, the length of the threaded line can vary from 2 to 5 meters. The end of the line is inserted into the head into a special technological groove or hole, and the winding is carried out in the direction opposite to the working rotation of the bobbin. Most reels have arrow marks on the outside of the body that indicate the direction of travel of the grass trimmer reel.

After winding, you need to leave a free end of 15-30 cm to enhance the centrifugal force, which is decisive when removing the trimmer line in automatic and semi-automatic spools. We pass the left end through the working hole of the coil and assemble the head.

How to properly wind the line around the spool of the grass trimmer?

Despite the fact that gardening equipment has been used for quite some time, it is still a novelty for some owners of private houses. This is why there are often questions about how to properly wind the line on an electric or gasoline grass trimmer.

This is essentially a simple operation, but all its stages must be performed correctly in order to achieve the desired result. over, in the operating instructions, only a few manufacturers provide an answer to this painful question. Explore the article and find out how the line winds around the reel of the grass trimmer.

How to wind the line onto the spool of the grass trimmer

First of all, you should be aware that grass trimmers have different working attachments. The reel can be designed for different lengths and thicknesses of the line. this point should be taken into account when purchasing consumables.

So how do you load the line into the reel of your grass trimmer? All work is divided into several stages:

  • First you need to disassemble the grass trimmer head.
  • Unscrew the nozzle by rotating the drum to the right.
  • Press with your fingers on the two latches located on different sides of the entrance, and remove the top cover of the nozzle. You can pry off the cover with a screwdriver. This should be done carefully: reels with automatic line feed have a spring that can forcefully throw the cover along with all the contents of the reel.
  • Remove scraps of old fishing line.
  • Now you need to find the middle of the line. To do this, unwind it to the required length (for example, 10 m), cut and fold it in half.
  • Hook the middle of the line into the existing groove or insert it into the hole specially designed for this. And start winding. Direction is indicated by an arrow, which is usually located on the grass trimmer reel body (usually against the rotation of the drum). Some models have a double-sided spool: in this case, the line should be wound in different directions: one end in one direction, the other in the other, while the loop of the line must be inserted into the dividing slot located in the middle.
  • Leave loose ends of the line about 20 cm each. Later they will need to be fixed in the recesses.
  • And finally, the last step will be the assembly of the drum. Reinstall the washers and spring. On the upper ring of the reel there are two notches where you need to tuck the antennae of the fishing line. Thread them through the holes and place the spool in the drum, trying to tighten the line without displacing the spring.
  • Place the drum cover on top and close it with your fingers. The latches will snap into place with a distinctive click.

When you turn on the grass trimmer, the excess line will be cut off by the trimming blade.

As you can see, winding the line around the reel of the grass trimmer is easy: the main thing is to do everything right. And here are some more tips that will come in handy when choosing a fishing line, winding it and subsequent work:

  • fishing line comes in different thicknesses and with different sections. The best option for winding is the “native” line for this model;
  • never use fishing line or metal cables for the grass trimmer. Such a substitution may seem effective, but it is very dangerous. Jumping off a working grass trimmer, the cable can seriously injure not only the lawnmower himself, but also those around him;
  • the line is cut when the working grass trimmer touches hard objects. Try not to allow this, otherwise you will have to stop each time, turn off the device and rewind the line on the reel;
  • Use regular line for cutting lawn grass and pigtail line for coarse weeds. It is more durable and will not constantly cut.
