Instead of fishing line for a grass trimmer with your own hands

How to cut a bottle into tape

Before you start making a homemade cord, you will need to prepare the material itself, namely a plastic tape of the required width and length. To dissolve a PET bottle onto a tape, various devices are used, the manufacturing algorithm for which can be found on the Internet. If you are going to mow large areas overgrown with grass, and you need a lot of homemade cord, then, of course, it makes sense to make a more complex bottle cutter from a corner or U-shaped aluminum profile. The process of making a bottle cutter is shown in this video.

But if you are not interested in mass production of plastic tape, then from time to time you can dissolve the bottle into strips in a simple way.

  • Take a regular PET bottle cork.
  • Cut it in half (but not completely).
  • Remove all bumpers inside the cork.
  • After folding the cut cork in half, pierce it through with a knife as shown in the picture below, being careful as the plastic is very hard. To facilitate the process, the tip of the knife can be heated.
  • Use scissors to cut the bottom of the plastic bottle (as straight as possible, without jagging). Insert the bottle into the fixture from the side where the knife blade is sharpened, and start to cut in a little. When a small strip appears. just start pulling it.

Thus, the entire plastic container will dissolve into a tape of the same width.

A -sized version of the bottle cutter, which you will always have at hand, can be made from a regular pencil sharpener, preferably made of aluminum. Details on how to make it are shown in this video.

Grass trimmer line and reel composition

The last criterion to pay attention to. the composition of the equipment for the grass trimmer. Brush cutter reels are made of plastic.

But the fishing line can be made from a wide variety of materials. How to wind a fishing line on a grass trimmer according to the application price in grass with a fishing line. Among them, nylon is worth noting. How to replace the line with a STIHL fs 55 grass trimmer in the STIHL fs 38 grass trimmer bearing grease. The line made of this material has high wear resistance, can withstand high temperature drops and increased loads. In addition, during long-term storage, nylon does not delaminate and does not lose its performance. All this directly affects the life of the line.

Many users of mowers, both electric and gasoline powered, some time after using a purchased line, ask themselves the question: what can be used to replace it? If you exclude dangerous options (chain from a chainsaw, a blade from a hacksaw, wire, cable, string, etc.), which can cause serious injuries to the user and others, then the best way out of the situation is considered to be a homemade fishing line from a plastic bottle.

Grass trimmer line and reel: how to make the right choice

Grass Trimmer Spools Modifications

The spools (heads) for the grass trimmer can be of various modifications. Tuck the line into the grass trimmer. Using the Makita um 4030 grass trimmer as an example. How to thread the line into the grass trimmer. Single-line (with one line of fishing line) are suitable for trimming the lawn, and for clearing areas and mowing grass. two-string, with manual string length adjustment or automatic line feed.

Modern manufacturers are increasingly producing universal brushcutters with two-string automatic reels.

Here the choice depends on the individual model and on the purpose of the grass trimmer. This reel is attached to the grass trimmer as well as how to install the line on the drum. However, if you need to mow, for example, an old shrub, the line will not work for this, as it will break immediately. For such purposes, it is advisable to use a brushcutter equipped with a metal knife.

Changing the line in the trimmer: 2 easy ways

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.


Method 2. two segments

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

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

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 tips are cut into the holes in the grass 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 grass trimmer spool body

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

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).

Button spool snaps into the grass trimmer spool housing.

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.

Preparing for replacement

For clarity, the mowing head (spool) was removed from the brushcutter. To replace the fishing line, you do not need to remove it, everything is done locally. It doesn’t take long.

We disassemble the spool of the grass trimmer. it rests on the latches. Remove the cover by pressing on the latches. If you do not have enough effort to do this with your hands, then use a screwdriver.

The spool consists of the following:

  • Spring casing
  • Cover with locking latches
  • Button coil

The principle of operation is as follows. By pressing the button, the spool presses on the spring and comes out of the locking grooves in the spool cap. Holding in this state, the reel can be twisted, thereby adjusting the length of the line. When the button is released, the body spring returns the coil to its original fixed state.

On the bottom of the reel there are several holes for different diameters of the lines. They may differ from trimmer manufacturer. In some cases (like here) they are signed, in others they are not.

These holes are needed to fix the line when changing it. After winding the fishing line on the bobbin, the ends of the latter are inserted into them. This is to prevent the scaffolding from unwinding when the coil is installed in the grass trimmer body. In other words, it makes it easier to change the line.

There are models without specifying the diameter of the consumable. Then, in order to find out what the maximum diameter of the scaffold can be used, it is tried on along the holes for the outlet of the fishing line from the body of the spool of the grass trimmer (see the figure below).

The reel has two line sections separated by a baffle. They may not exist. They are needed only to delimit and facilitate the winding of the consumable.

First, they are determined with the required length of the loess. The latter is wound into one of the sections of the coil so that it does not go beyond its limits. In this case, 3 mm was wound, the length turned out to be about 2 meters. Those. for two sections you need a 4-meter segment. this is for the 1st method. For the second method, you need two segments of 2 meters each.

Now you need to figure out which way you need to wind it. To do this, many trimmer manufacturers apply special designations to the spools, such as in the figure below.

If no such designations were found, then you need to pay attention to the spool body. There is necessarily an arrow that indicates the movement of the mowing head. The line is wound in the opposite direction.

DIY grass trimmer attachment

For many summer residents, a grass trimmer has long become a familiar and almost irreplaceable technique. But it is not always possible to purchase a model that meets all needs. It happens that the grass trimmer copes with fresh young vegetation easily, but there is a desire to clear a place behind the fence or along the driveway, and the tall matured grass turns out to be too tough for the technique.

DIY grass trimmer attachment

We offer the option of self-production of the grass trimmer attachment from simple (almost improvised) means.


  • metal perforated plate (100 mm x 240 mm)
  • 2 hacksaw blades for metal
  • 4 screws and 4 nuts M5
  • 4 washers and 4 oversized washers

From a safety point of view, hacksaw blades should not be completely hardened.

Everything you need to make a nozzle

The most difficult part in making a nozzle is to symmetrically mark and make holes for the knives and the grass trimmer shaft. That is why a ready-made perforated plate is chosen.


First you need to make the base of the nozzle. To do this, cut a square with a side of 100 mm from a metal plate with an angle grinder. You need to mark it in such a way that there is a hole exactly in the center (at the intersection of the diagonals). To do this, measure a distance of 50 mm from the center of the selected hole perpendicular to the short side of the plate and outline the cutting line for cutting.

We mark the base of the nozzle

Cut off the excess and get a square of 100 mm x 100 mm. Now you need to round the corners a little and drill the center hole for the grass trimmer shaft.

Round off corners and drill center hole for grass trimmer shaft

We cut the canvases for metal, measuring 8 cm from each end.We get 4 blanks with ready-made holes.

We cut canvases for metal

These blanks need to be shaped like knives. To do this, we outline the cut line by eye (special accuracy is not required), fasten all 4 blanks together and grind off the excess.

Cut out knives from blanks

As a result, we get knives of the same weight and size, they can be sharpened a little on one side. Now all parts of the homemade grass trimmer attachment are ready, you can start assembling.

Everything is ready for assembly

Put a small washer on the screw and insert it into the corner hole. We put on the knife from above, placing the sharpened side in the direction of rotation of the grass trimmer shaft. This is followed by a large washer and a nut that is not tightened so that the knife rotates freely. In the same way, we attach the other 3 knives.

Fixing the knives

The end of the screw must be riveted so that the nut does not fly off.

The end of the screw must be riveted

The attachment is ready. It is installed with nuts to the ground and fixed in the same way as the three-blade knife that comes with the trimmer. When colliding with a stone, the knives fold and go inside a little.

This idea was suggested by our regular video author Tatiana (Tula region). You can see in more detail the whole process of making such a grass trimmer attachment and find out some of the nuances by watching the video that she prepared.

When working with a trimmer, it is important not to forget about safety, using any attachments, especially homemade ones.

We suggest discussing this idea in the Комментарии и мнения владельцев to the publication. Share your thoughts with us, and also tell us about your good solutions.

Without accepting any of the sides of this sharp (literally and figuratively) discussion, let me show you one of the latest models of brushcutters from the German company Robert Bosch. It provides for both a deflecting knife and an arcuate bracket, which excludes the “striking” of the knife on objects not foreseen by mowing. I show the general view of the brushcutter and the knife itself, in two positions. General view of brushcutters

Knife in a deflected state

Folded knife

Good evening everyone! Exactly three years have passed since the discussion of the “acute” problem for the grass trimmer. Over the past 1000 days, a clear picture has emerged: “Glory to the author, the craftsman, who conducts an experiment on himself to reach the yield point of the metal from which these knives are made. He has every right to risk his own health. ” Nowadays in stunt films you can often see a frvza. “Do not try to repeat the movie stunts that were performed by professional stuntmen.” The very first article was supposed to end with approximately the same phrase: “Dear summer residents. This is my personal experiment. If you are not sure of your locksmith’s abilities, please do not repeat it. AND MOST IMPORTANT. I am not responsible for the operation of the tool, made in the footsteps of my articles.” And the last thing. Do I see errors, judging by the photographs, of the execution of this tool. Yes, I see, and a rude one. Look closely at the plate, which is the carrier for the four knives. Look closely at the FAR RIGHT HOLE in the photo.

Alas, the author of this device does not even suspect how the hole for the shaft should be made.

I inform you that the distance from the point of the hole closest to the edge of the plate to the very edge should be NOT LESS than the diameter of the hole itself. Students of mechanics will learn this truth no later than the second year of the institute. What do we see here? A thin isthmus resembling a narrow PEREKOP, making a peninsula out of the Crimea. This is a priori the place that is weak in this design. it experiences the same loads as other knives, but the “digging” there is very thin. Where it is thin, there and I would like to hope, and quite sincerely, that over these three years this isthmus has not undergone loads comparable to the yield strength of this metal, but rather the alloy from which the perforated plate is stamped.

How to load the line into the grass trimmer?

So, we are faced with the task of correctly loading the line into the grass trimmer. Let’s take a closer look at where to start its implementation and what pitfalls can await us in the process.

Care and prevention of breakdowns

Maintenance and prevention of inertialess breakdowns are by no means difficult.

Important! The angler should consider as a rule mandatory pre-season maintenance of the device, as well as elementary surface cleaning and removal of moisture from the product after each end of fishing.

In addition, it is worth monitoring the careful transportation of the mechanism, avoiding bumps and falls. On the very same fishing, you should not put rods with reels on the sand, and also try to lower the device into the water as little as possible. Attention and careful attitude to the tackle as a whole prolongs the operational potential of each element of the tool for a long time, including the spinning reel we have considered.

There are fishing lines with improved aerodynamics with corresponding dents, scales and notches, a similar product makes less noise, but it is used only on petrol cutters, since the exit of such a thread from the reel is difficult, it is used in most cases with discs into which segments are inserted. This video is about how to change the air filter on your Husqvarna trimmer (brushcutter). The disadvantage of such a product is its fragility.

In most cases, in gasoline trimmers with an engine power of more than 1.5 hp. use cords with an iron cable inside. in this video I show how to disassemble the coil of a gasoline grass trimmer, as well as how to properly wind the fishing line on it. Look carefully at the video I have on a similar trimmer on how to replace the fishing line in. This thread is perfect for cutting dry grass and small bushes. The presence of a core has a positive effect on the wear resistance of this material. The disadvantage of such a cord is its price, which is significantly higher than the listed opponents.

Damaged spool spool

An unpleasant defect is considered damage on the sides of the spool. Most often, a malfunction of this direction arises as a result of shock loads on the body of the device, less often, and this problem of a poor-quality product, it is the cause of the development from the use of rigid cords. Microcracks, chips and notches appear on the side of the spool. When casting, the descending line clings to obstacles and irregularities of the part, which leads to a decrease in the range parameter of the tackle, and in the worst case, to deformation of the cord and its further break even with a minimum load.

Do-it-yourself spinning reel repair consists in grinding the spool rim and completely eliminating irregularities and roughness, leading to the discomfort of casts and a decrease in the breaking loads of the forest. For these purposes, sometimes it is enough to use fine abrasive sanding paper and a couple of minutes of uncomplicated work.

Spinning coil structure

Undoubtedly, in order to repair a coil, you need to imagine its structure and principle of operation. Without exception, all non-inertia gears are assembled at the factory from the same type of units, which differ in size depending on the size of the mechanism. The main components of the device are the following parts and details of the product:

  • body;
  • gear drive;
  • brake clutch;
  • rotor;
  • reel seat support;
  • reverse direction switch;
  • spool mounting rod;
  • line layer with bow and roller;
  • toothed wheel with shackle.

Depending on the modification and purpose of the inertia machine, or as the fishermen call it a meat grinder, it can be supplemented with specific functionality inherent in a particular model.

Disassembling the coil

The disassembly of the coil is carried out according to the clear algorithm presented below. In the process of performing work, it is important to remember the sequence of operations and scrupulously delve into the nuances that contribute to the accuracy of the work associated with the application of efforts to disconnect the threaded, sleeve and locking connections of elements and units of the product.

  • we unscrew the brake system nut and spool;
  • remove the gears and washers placed under the spool;
  • dismantle the coil handle;
  • we unscrew the clamp nut in the mechanism device;
  • disassemble the rotor;
  • dismantle the fishing line;
  • dismantle the latch mechanism of the line guide;
  • dismantle the line pulling roller;
  • we unscrew the screw of the reverse locking device;
  • dismantle the switch lever;
  • unscrew the screw of the plug;
  • dismantle the plug;
  • dismantle the wall.
