In these types of reels, the number of grooves for winding the mowing line lying inside the reel must be determined:
- one groove. both antennae are wound together along one groove;
- two grooves. each barbell is wound on a separate groove.
In both cases, a line with a length of 2-3 m is taken.In reels with one reel, the line is pulled into a through hole, its ends (antennae) are folded together and aligned, and then wound in the opposite direction of rotation of the drum from the side of the rod. the arrow usually indicates the correct winding direction. If there are fixing grooves, the ends of the mowing line can be traced in them or held by the fingers of the free hand, pass through the through hole in the outer half of the bobbin, the bobbin is closed and attached to the rod finishing.
The difference between winding the mowing line on reels with two reels is that initially the 2-5 m length of the mowing line is folded in half (to define the middle fold), and the folding loop is inserted into a special groove between the grooves. Both cutter line tendrils are wound around each groove, antenna retention and spool assembly are the same as described above for single groove.
The first implementation of this procedure can be long and rather laborious, but with time and experience, this task will be solved much faster and easier.
The video below will clearly show you how to fill the line in and rewind it correctly. this operation is not difficult and will surely succeed with some patience:
The final moment of the instructions
Usually, the process of changing the line on a particular model trimmer is popularly described in the accompanying documentation. Another question is that this documentation is often supplied in a foreign language, since the notorious lawn mowers for the most part are imported products.
Meanwhile, there is a much simpler, more economical and beneficial for human health and nature way. putting in order the lawns of an ordinary peasant scythe. Grass scythe blade:
- does not “tear” the stems of grass,
- does not uproot plants,
- cuts neatly,
which is further accompanied by abundantly growing greens, and not the formation of dead wood as a result of the work of the grass trimmer.
Replacing the line on the brushcutter.
How to wind the cutting line yourself on the reel of brushcutters (grass trimmers)
Step one: securing and laying
Fold the end of the line in half. Place a blank over the spool on each side of each half of the winding zone. Wrap both halves completely around the winding drum. Pull the line through the loop.
The procedure for preparing the line engagement in the area of both winding sections of the drum. The loops are placed in specially made cutouts, after which the line is wound in each zone
It is enough to pull the line tightly and plant the knot in the groove made on each side of the winding drum.
How to thread the line into the spool of the grass trimmer
In order to wind the line, it will take about 10-15 minutes. What is a grass trimmer coil? Plastic body with a cassette inside, on which there is a special hook for easy winding of the fishing line. Almost all trimmer reels have a similar fastening principle, this is a central screw-button, when pressed, it becomes possible to pull out the line of the required length. The photo below shows a few examples of different trimmer spools.
The bobbins of the trimmers, the motor of which is located at the very ground, have a different attachment to the axis of rotation, they have two buttons on the spool located on the sides that need to be wrung out, otherwise the replacement of the thread is no different from other cassettes.
The principle of correct winding of the fishing line is similar in all of the above cases, therefore, for example, consider the standard version with two antennae.
To remove the spool with the fishing line, you need to unscrew the screw located in the center, but note that the thread is left there, so you will have to turn it clockwise, this was done on purpose so that during operation it does not open under the influence of centrifugal force.
Next, using a screwdriver, disassemble the head and remove the spool, onto which the fishing line is directly wound. Having measured the required length and folded in half, you need to tuck the fishing line into the spool, eventually bringing its ends opposite each other (for this there are special slots for fixing).
After that, it is necessary to assemble the head in the reverse order, threading the ends of the cord into two corresponding holes.
If you have any doubts or it is not entirely clear how to load the line on the grass trimmer, we recommend looking at how to properly wind the line into the lawnmower. In this video, step by step, the instructor will open the trimmer head, measure out the required amount of line, usually two to four meters, and demonstrate assembly and installation on a grass trimmer.
The first way
The prepared segment (in this case, it is 4 meters) is bent approximately in half. one segment should be 15-20 cm longer, and inserted into a special slot located on the dividing wall.
The line is wound in the direction determined earlier. This is done in an interference fit, the line is neatly distributed. In this case, you need to wind a segment that is longer in the section that is closer to the button.
There are designs that do not provide for dividing the coil into two sections. This does not change anything, the line is wound in a similar way. You just need to make sure that the segments do not overlap with each other.
The first should end that section, which is located at the bottom of the coil, i.e. the one closest to the fixing holes.
This tip fits into the corresponding hole in diameter. The line is securely fixed.
A long segment is wound half a turn. There he is similarly fixed. In this case, the segment crosses another section of the coil.
A long segment is wound another half turn
The fixed ends of the coiled line are inserted into the holes in the spool body of the grass trimmer.
The fixed ends of the coiled line are inserted into the holes in the spool body of the grass trimmer
The coil is attached to the body. The ends of the fishing line are pulled with effort so that the fishing lines previously fixed in the holes of the reel jump out from there. It is easily identified by the characteristic sound (click).

The line was changed successfully. In this case, you need to put it back on the grass trimmer and you can start mowing the grass.
It should be repeated, there is no need to remove the spool from the grass trimmer. this was done to clarify the process of replacing the fishing line. You can disassemble the spool in place, wind it on the spool and put it back.
Tips can and should be trimmed to prevent them from hitting the grass trimmer cover.
Step three: complete the head assembly
Pull out the ends of the line through a pair of oval spool slots. Replace both washers and spring (if any) with the supplied new parts. Bend both ends of the line at right angles.
The final technical touch of the process of changing the line on the trimmer is the imposition of the cap on the head, followed by fixation by means of pushing force and slight twisting.
Pass each end into the hole at the base of the winding drum. Install the coil in the inner area of the head, resting on the spring. Put on the cover, align with the base and lightly push downwards with a small counterclockwise rotation, place the cover on the tabs of the clips. This completes the replacement procedure.
Which line to choose
Before you stock up on this material for dressing in a grass trimmer, you need to decide on the choice. After all, the usual so-called round fishing line is far from the only existing species. How to choose the most suitable one? First you need to determine the working conditions.
Selection by type. Round line is the most common. It will fit any coil with rare exceptions. This type of consumable is suitable for cutting fresh, juicy grass. But with the mowing of the so-called dead wood, such a species may no longer cope. It is pointless to mention attempts to mow bushes with this thread.
In addition to the usual type, there are others that have sharp edges. Usually they are made with an asterisk or a square. The presence of sharp edges is the main feature and key difference between these threads.
It is thanks to this feature that the threads of these types are able to mow dry weeds. But sharp-cut threads are not without drawbacks, the main of which are quick wear and strength, which is noticeably inferior to the round type.
In addition to the already mentioned types of woods, there are also interesting and common varieties. Especially among them can be noted fishing lines, inside which a metal wire is stretched. This type of thread is often used in gasoline powered tools with an engine over 1.5 horsepower.

Metal-cored threads come in both round sections and sharp edges. Regardless of the type of section, such threads are the best suited for overcoming difficult-to-cut plants. Threads of this type can easily mow not only dry grass, but even small bushes.
The wires with a wire inside compare favorably with other types of consumables for their incredible wear resistance. Unfortunately, this feature has a more than noticeable impact on the price of this type. The cost of yarns with a core is much higher than the cost of other types of yarns.
How to replace line in any trimmer
How to replace the line in any trimmer So, first unscrew the nozzle. This should be done by rotating the drum to the right. Here we have a drum with the remnants of an old fishing line in our hands. We open it. Most often, the lid is closed with latches that can be opened with a screwdriver, threading it through the holes and slightly pressing. Or you need to squeeze the latch and turn the cover in the direction of the arrow. In this case, the lid itself must be held, since reels with automatic line feed have a spring that, when straightened, can throw out all the inner parts of the drum. Gently pulling out the reel, remove the scraps of fishing line from it.
Now you need to take 5 meters of new line and fold it in half (to find the middle). In the middle part of the reel there is a notch (in some designs. a hole), for which we need to hook our fishing line. There is also an arrow on the spool showing the direction of winding. An important detail. if the reel has two compartments, then one half of the line should be wound in one direction, and the other in the other. When finishing winding, you need to leave 15-20 cm of line free. There are also two notches on the top ring of the coil, through which these free ends need to be passed. We dealt with the winding itself.
The last step in the line replacement process is to assemble the drum. First you need to install the spring and washers in their place. Then, holding the reel with one hand, with the other you need to thread the ends of the line into the corresponding holes on the sides of the nozzle. After that, install the coil in its place, tightening the line and being careful not to dislodge the spring. When all the internal elements of the nozzle take their places, you can close the drum with a lid. You just need to make some effort to ensure that the latches fall into place. Voila! The mowing head is ready for use! When choosing a fishing line for your motor scythe for grass (gasoline or electric), you should dwell on some points, which we will talk about in detail.
Line diameter. Engine power determines which maximum line diameter can be used for a given grass braid. For example, the manufacturer of an electric grass trimmer with a power of up to 1 kW recommends using a line of ø2 mm, and at values of about 500 W, only ø1.5 mm. Also, the manufacturer of any powerful curved bar grass trimmer recommends using a ø2mm line. The gasoline engine is more durable than the electric one, so you can use thicker line there, which means stronger line, which allows you to cut more grass and work longer. On grass cutters with a straight bar, you can select the line according to the following simple algorithm: the diameter in millimeters corresponds to the engine volume in tens of cubic centimeters. For example, for a Husqvarna 128R lawn mower with an engine displacement of about 25 cm3, use a line of ø2.5 ± 0.2 mm. For more powerful hedge trimmers with volumes of more than 40 cm3, the diameter of the line is limited only by the geometric dimensions of the outlet openings of the mowing head. no more than 4 mm. So, a thin line (about 1.5 mm) cuts well cultivated lawn grass, and a thick line (for example, 3.0-3.5 mm) successfully destroys weeds and even young shrubs.
Line shape. The simplest and cheapest to manufacture is a round line. However, the requirements of ergonomics and environmental protection limit its use. due to its physical properties, it creates an unacceptably high level of noise (which is comparable to the noise of the engine itself). This is the classic Husqvarna or Oregon RoundLine or Chipmaster. To reduce the noise produced by the line, it is given a special shape. they make it spiral like Oregon DuoLine Plus (noise reduction by 15 dB) or with special transverse grooves like Husqvarna Whisper (-8 dB). Following the school laws of physics, the “working” part of the line during the mowing process is only the end surface, not the side surface. However, to increase the “sharpness” of the line, i. E. to increase efficiency, the cross section is changed from round to faceted: star-shaped, square or square with teeth. Oregon StarLine, Nylsaw or Flexiblade. For example, according to the calculations of experts, Oregon Nylsaw line, due to its square profile, is 27% “sharper” than its round counterpart, which clearly affects the increase in mowing speed.

How to change the line on an electric trimmer
a grass trimmer is a necessary and useful tool for a summer cottage and a private house. Many people own and actively use it, but not everyone knows how to replace the line in the trimmer, especially at first.
In this instruction, we will walk through the entire replacement process step by step. Looking ahead, there are two ways to line the trimmer spool. There is no fundamental difference. the difference lies in the fact that in the first case one line will be refueled, folded in half, and in the second there will be two such lines.
On a reel with one tendril
It is very easy to screw the line onto a reel with one tendril. In such designs, depending on the brand of grass trimmer, from two to five meters of cord is placed. The edge of the line in the spool must be tucked into a special hole or groove, after which the string is wound in the direction opposite to the rotation of the reel during operation.
Advice! To understand in which direction to wind the thread, you should look at the spool body. usually there are marks on it indicating the direction of the spool movement during operation.
After the line is wound, you need to leave a small piece (15-30 cm), thread it into the spool outlet and reassemble the head.
Coil with two working tendrils
In this type of spool, you should determine the number of grooves for winding the line, lying on the inside of the spool:
- one groove. both antennae are wound together in one groove;
- two grooves. each antenna is wound on an individual groove.
For both cases, a line with a length of 2-3 m is taken.In single-groove reels, the line is pulled into a through hole, its ends (antennae) are folded together and aligned, after which they are wound in the opposite direction of rotation of the bobbin on the rod side. inside the arrow usually indicates the correct direction of winding. If there are fixing grooves, the ends of the fishing line are threaded through them or held with the fingers of the free hand, they are threaded into the through hole of the outer half of the bobbin, the spool is closed and attached to the trimmer bar.

The difference in line winding in double-groove spools is that initially a 2-5 m long line segment is folded in half (to determine the middle fold), and the fold loop is inserted into a special groove between the grooves. Both antennae of the fishing line are wound each along its own groove, fixing the antennae and assembling the coil is similar to the above option with one groove.
The first execution of this procedure, perhaps, will seem long and rather laborious, but with time and experience this task will be solved much faster and easier.
The video below will clearly show how to thread the line into the spool of the grass trimmer and wind it correctly. this operation is not difficult and with some patience it will certainly be crowned with success:
Changing the line to a disc
Depending on the type of vegetation covering the garden area (lawn) and requiring removal, the line changes to a disc. This is necessary, since the cord is used only for grass of a small height, and if you need to mow tall growth, tree shoots or bushes, instead of a string, it is better to use metal or plastic knives-discs. It is very easy to install them correctly, the detailed process is usually described in the owner’s manual and is similar for trimmers of different brands, be it Al-Co, Oleo-Mac, “Patriot” or other brand equipment. To change the fishing line to knives you need:
- block the shaft and remove the coil by turning it clockwise;
- put the knife on the sleeve;
- install the fixing cover and tighten the nut in a counterclockwise direction, and then tighten it with a wrench.
You can read in detail how to change a spool of line to a disc in the instruction manual of the device.
Coil with one working tendril
The simplest option and uncomplicated sequence of actions:
- The dimensions of the reel and the length of the original factory winding determine the recommended length of the line for winding. 2 5 m.
- One end of the line is inserted into the fixing technological hole located inside the spool.
- The fishing line is wound on the drum in the opposite direction of the spool rotation on the trimmer product. as a rule, on the inside of the reel, an arrow indicates in which direction the winding is carried out.
- A small section of the fishing line is left free to lead it out. it is fixed in a specialized groove on the inner side of the bobbin, designed to hold the winding when assembling the bobbin into working condition.
- The left end of the line is passed through the hole in the outer part of the reel.
- The bobbin halves are assembled and put on the trimmer bar.
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.
On a note! To understand how much line to wind for the reel, you need to wind it on the bobbin so that the height of the skein does not exceed the diameter of the sides. If the cord protrudes beyond the edges, the spool cannot be hidden in the casing.
On a reel with two antennae
In bobbins of this type, it is necessary to inspect the inner side of the coil and determine the number of grooves for winding the cord provided in it.
Important! If there is only one groove in the coil, then both antennae must be wound along a common groove, if two, then along separate tracks.
For winding, you need to take a piece of fishing line with a length of two to three meters. For spools with one groove, thread the line through the hole, align the whiskers, align and wind on the spool in the opposite direction of its rotation during operation. If fixing grooves are provided, thread the ends of the cord through them, then pull them out into the outlet, then close the coil and put it back on.
For double-fluted spools, the difference is that the string must be folded in half. Next, you need to charge the middle of the fold into the groove between the grooves, then wind each of the pieces of fishing line along its own path, fix the antennae and assemble the coil as well as a spool with one track.
