What can replace the line for a trimmer on a chain saw?

Chain from a chainsaw on the trimmer for grass with his hands

At the heart of almost any home-made gasoline saw is the introduction of its universal drive, which can be used for a large number of different devices. Scope of their use is very broad: cutting stone and metal, pumping water, removing snow, drilling holes and wells, riding, moving various objects, swimming and also flying.

Execute the potential ability of a chainsaw with a variety of accessories and attachments. At least in the basis of any modification is the usual principle of selection of motor power: the output shaft is connected to the desired master device. The presence of a massive motor, small size and comparably light weight of this tool, autonomy and the ability to work in virtually extreme conditions make its capabilities truly endless. Of no small importance is the convenient design of the clutch clutch, which protects the nodes and complex saw from breakage and overload. A tool made from a chainsaw is characterized by its own density, so it is used in virtually every position.

Our client remains self-made devices can be divided into 2.Group 7:

  • ordinary devices (angle grinder, ice drill, pump, winch, single-axle tractor, boat motor, bike, moped);
  • more complex mechanisms and items (saw, snowmobile, snowmobile, aerial sled, electric station, helicopter, one-piece knife).

Different brands of chainsaws are used to make all of the available devices. When selecting them, you should consider the power needed for the normal operation of the remodel. In most cases, for the production of various devices use these brands of chainsaws: Druzhba, STIHL, Ural.

Below are the different versions of devices made from chainsaws. Who wants to use such ideas in their own economy. From a chainsaw with a little extra material is made:

angle grinder. The main system of such a device. bearing unit with a shaft. On one end of it, a driven pulley is installed, which rotates by means of a V-belt. The other holds the mandrel for the cutting discs. Depending on their brand of angle grinder certainly cut stone, metal, bricks and other building materials.

Ice Drill. For smooth operation of the device is not desirable speed screw large, because you need to use a gearbox, made in the form of a worm or V-belt transmission. Such a device can be used for building foundations with spiral piles and for other ground work as well.

Pump for pumping water is used for garden irrigation, emergency water supply, draining ponds, otherwise said flooded cellars. Such a nozzle is the usual centrifugal pump, equipped with a bracket for mounting on the saw and a pulley, driving the turbine pump in action.

Winch, which uses a chainsaw drive. The pulling power of such a device is directly related to the power of the saw motor. Of course it can be substantially increased by using the auxiliary unit. This device is equipped with such additional parts, as a diverter block, hooks, straps, anchors.

The boat motor from a gasoline saw. a beautiful candidate for the purchase of an expensive motor. To ensure the movement in 20 km / h enough to install on a boat homemade boat motor with gearbox (gear ratio of 2.4:1) and a 3-blade propeller, 210 mm across. At the same time the fuel consumption will be equal to only 1 liter per hour of engine work.

Gasoline grass trimmer

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

Device gasoline trimmer is simple, it can be easily dismantled if necessary

There are electric and gasoline modifications. The former are not fueled, 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 cheaper than lawn mowers. They cope with grass and bushes, so these mowers are used at home and in industry. For convenience, the technique has straps that fit over your shoulder. That way, there’s less strain on your arms and back.

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

Initially, before you tuck the trimmer line into the grass trimmer reel, it must be removed from there. The reel or tip is a device that is located inside the mowing head, reel or drum. There are different kinds of heads (depending on the manufacturer), but the principle of changing the line on the spool is the same for all. The first thing to understand how to remove the head from the tool, as well as how to get out of it a drum with a fishing line.

Instructions on how to unscrew the manual head on the trimmer are as follows

  • Turn the tool upside down and, if necessary, clean the head. Grasp the two catches on the cover (on the mowing head) symmetrically with two fingers of one hand. After lightly pressing them in, remove the protective cover from the reel
  • Next, the line spool must be removed from the reel shaft. It is mounted without any fasteners on the shaft, so it can be removed with just one hand
  • The main part of the reel is fixed with a screw, which should be unscrewed with a screwdriver with a suitable tip or a bit
  • To unscrew it, hold the base of the drum with one hand and unscrew it counterclockwise with the screwdriver with the other
  • Then the dismantling process can begin. It is not necessary to pull it with all your might, but by rocking it slightly sideways, to slowly disengage it from the metal shaft on which the drum is seated
  • When reinstalling it, the head should be seated in the slots of the square shape

This process is not difficult, and as you understand, there is no need to dismantle the entire head, if you know how to perform the replacement. Consider such nuances during disassembly:

  • Periodically removing the head is recommended to prevent corrosion of the threaded joint. If a screw is never unscrewed, it can be difficult or even impossible to unscrew it when required
  • If a screw has a square drive head, a screwdriver or suitable size drill bit must be selected for unscrewing to avoid slipping on the head
  • When reassembling the system, the threaded seating should be coated with a lubricant, e.g. grease or machine oil
  • If the facets on the screw have slipped off, you can use special tongs to unscrew it
  • There are drums that do not require prior disassembly. To disassemble them, you should take hold of it, and rotate in the opposite direction of the clockwise direction

Knowing how to disassemble the reel, you should continue to figure out the process of replacing the grass trimmer line. The video below shows a detailed process on how to open the grass trimmer reel and disassemble it.

What can replace the line for the trimmer on a gasoline lawnmower?

I want to share with you some useful information for those who use a trimmer, which is also called a lawnmower, benzo. and brushcutter, and the residents of the sleeping areas of high-rise buildings dubbed it “good morning, country”. But, as it were, most wonder if there are such options as perpetual grass trimmer fishing line for trimmers with their own hands. In order not to bore users with expectation, I will say at once: “Yes, it exists, and it will outlive even the tool itself”.

First it would not hurt to understand what wears out the factory line for the trimmer, which constantly have to change, which is not entirely convenient, and sometimes this need can even spoil the mood, since there is simply nothing to replace. I’ve noticed that lawnmowers, in order to finish the job, are forced to use some wire instead of fishing line, and I’ve even seen on the Internet that they tried to use pieces of a soft hacksaw blade broken in half for this. there are holes on both sides for fastening. But all these attempts are ineffective, because the cutting element always breaks, or tears from hitting the hard trunks of the weeds, or foreign objects that are in the grass.

Instead of fishing line it is much better to use a thin steel rope. its threads are made from tool steel, which is not subject to corrosion, but has an extremely high barrier of strength. That is, in fact, the pieces of steel wire attached to the rotating disc of the brushcutter should last forever, at least much longer than the grass trimmer itself. But it is not exactly so, to be more precise, in order to ensure endless service life of the cable, its free end has to be sealed, which is not at all easy or even impossible to do in the home conditions. The point is that from frequent blows the tip of such a secant element will start to fluff up and gradually turn into a bundle of steel threads, which will get tangled. There is one conclusion: if it is possible to solder the tip like a sanitary wire. do it and use it for good health.

What cross section of fishing line to take?

Note that the nozzle can have at least nine different diameters:

Sometimes you may come across Chinese “nooneymov” nozzles, the thickness of which “floats” between the standard readings. What is the best line size for a grass trimmer?? Much depends on the power of the device. Here are the averages of the correspondence between the power of the line for grass and the diameter of the bait:

  • 1,3 to 1,6 mm. suitable for electrical devices up to 500 watts. This line is good for mowing young grass, the lawn and small weeds.
  • 2. 2.4 mm. they will work with electric and gasoline grass trimmers of 500 to 1000 watts. This string can be used for both sparse and dense vegetation, as well as for weeds like burdock, nettles, etc.
  • 2.7 to 4 mm. designed for petrol brushcutters rated 1000 W and higher. Even dry grass, brushwood and bushes can be cut with this line. Please note that 4mm diameter trimmer lines are very rare and are designed for very powerful petrol brushcutters, which are not usually purchased by consumers at home.

It is worth noting that a thin string, such as 1.6 mm, can not be put on the grass trimmer 1000 watts and above, as it will be very quickly consumed and the necessary result you will not get.

Also note that from a thickness of 2 mm the cord may have a steel wire core inside the nylon cord. Such a core increases the strength and durability of the cord. In addition, the steel wire cuts thick stems and dense weeds better. The core is most often equipped with a solid and twisted circle, as well as a solid and twisted square (twist). Here is an example of a twisted two-piece cord. Denzel Extra Cord.

What is the best line for a grass trimmer??

To answer this common question, you need to consider the main working parameters of the cutting cord one by one.

  • thickness. the larger the diameter of the line, the more effective it is in working with thick weeds;
  • Section. twisted and circular cords have proven the best. Another popular choice is “star”. Cords with a section of this type successfully cope with high, dense grass and young shrubs;
  • manufacturer. Husqvarna and STIHL cutting cords stand out for their high quality, durability and longevity. Their only disadvantage is the high price. In such cases, you can choose inexpensive cords brands Sturm, Forte or Intertool.

When choosing a fishing line, it is desirable that the gardener has the opportunity to test the cord with his hands. It is important to stretch the cutting cord and try to break it. If the line for the trimmer does not give way, then it can withstand a sufficiently high load.


The improved grass trimmer handles tree growth and tough weeds just as well as tender grass.

How the line head works on a brushcutter why you need to know the principle of operation

Depending on the manufacturer, the heads are not only different externally, but also internally. Most trimmers have a pressure spring inside (semi-automatic and automatic). Above is an instruction on how to disassemble a grass trimmer head without a spring, t.ะต. on a hand-held type head. The principle of dismounting a semi-automatic head with a spring inside is almost identical to the above instruction.

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

  • Inside the head there is a spool, which is seated on slits to prevent its free movement
  • The reel is actuated by a spring, which presses it to the slots in the cover structure
  • A line for the trimmer is wound on the lead, the length of which depends on the tool itself. This length is usually between 1 and 4 meters
  • During work, if the need to increase the length of the line, there is a pressure on the protruding part of the drum, by which it comes out of gear with splines. The line for the trimmer winds up from the reel, increasing in length
  • After releasing the required amount of fishing line, you should release the clamping, and continue to perform the work of mowing the grass

The advantage of a tool with a fishing line is that this consumable does not require sharpening, compared to metal discs. In addition, if a stone or wood gets in the way, the line for the trimmer is simply torn off, without negatively affecting the gearbox and engine of the tool, as it happens in the case of metal cutting discs.

Knowing the construction and design of the types of mowing or trimmer heads, it is necessary to proceed to consider the process of threading the line into the grass trimmer reel. After all, it is this point that most owners of special tools have difficulties with.

Types of trimmer heads for reels

The main element of the trimmer is the mowing head, which is a cylindrical body with a spool (bobbin) inserted inside. This is where the line for the trimmer (cord) is tucked in. The heads differ from each other in the way they feed and thread the cord. A total of three types of heads are distinguished:

  • Automatic. The wire is fed after the user reduces the engine speed. Automatic filament feed is very convenient when you need to perform a large amount of work. The disadvantage of this head is the high consumption of thread.
  • Semi-automatic. Using such a head does not require the user to perform any complicated manipulation. The principle of its work is arranged so that the line for the trimmer begins to extend automatically at a time when the grass trimmer works at full speed. You just need to bump the head of the device on the ground (this will remove the blocking of the line), and the cord due to the centrifugal force will move out of the bobbin. Then the line for the trimmer is cut to the required length with a knife, which is located on the protective cover.
  • Manual. To lengthen the cord, you have to stop the machine. After that, the line for the trimmer will need to be pulled by hand.

Types of trimmer reels

The products of the best trimmer line manufacturers are divided into two types:

There are many manufacturers of fishing lines, but only those brands that are widely represented in all specialized stores deserve attention.

    Champion offers the widest selection of lines from round nylon to monolithic two-piece cord. According to users, Champion has the best trimmer line for value for money.

What materials are used to make fishing lines and how this affects their reliability

Trimmer line is made of nylon, a polypropylene-polyamide core. Distinctive features of nylon are its following advantages:

  • Durable under proper storage conditions. Do not allow material to be stored in the sun or at low temperatures for extended periods of time
  • Lightweight, which allows for high speeds through the inertia of the head rotation
  • Wear-resistant. the material is resistant to wear and tear, and damage to the cord occurs only when hitting hard obstacles
  • low cost. this is convenient, because the material is consumable and a new line must be used all the time

This is interesting!When you cut the grass, the nylon line tears into pieces that get caught in the cuttings. These pieces are harmful to animals, so mowing with these lines for making hay is not recommended.

Sometimes cheaper polyethylene is added to the material, which reduces the reliability of the cutting equipment. Polyethylene cord wears out faster, so experience proves that it is more advantageous to buy a line for a trimmer made of natural nylon (it costs more) than to save money and buy a polyethylene cord.

Lines of 2,6-3,3 mm thickness consist of graphite or steel rods besides nylon. a two-part cord. The presence of rods not only increases the efficiency of mowing the grass, but also reduces the rapid wear and tear of the line. the result is that a line with a larger cross-section lasts longer than a thin trimmer line. There are also cords with metal particles in the composition. These additives are also designed to increase the efficiency of grass mowing, and increase the strength and wear resistance parameters of the material.

This is interesting!Choosing a fishing line for your grass trimmer, it is necessary to pay attention to the head or spool. These parts indicate the parameters of the cross-section of the cord that is allowed to be used.

Sectional views

There are many kinds of fishing line, you can ignore the color. as such, there are no general standards “color-characteristic”. The important factor is the type of cross-section of the string, it is chosen depending on the type of grass.

  • Circle. the universal line for trimmers. While smooth lines make more noise when mowing, coiled lines are quieter but use up more quickly (like all coiled lines).
  • Square or polygonal. This line for the trimmer is more effective than a round one. the sharp corners cut the stems faster and better quality.
  • Sprocket, ribbed or twisted square. Has the maximum efficiency and speed of shearing.

Good to know! It is strictly forbidden to use metal wire, ropes or rods instead of fishing line. Such equipment easily cuts even leather shoes and can seriously injure the operator.

Technical specifications at a glance

In stores, fishing lines are sold in special packages, and as such, there is no information about them, only the length of the string and the value of the cross-section. For beginners, this will not be enough, so it is necessary to ask for help from an expert. But you can also study all the important information yourself and choose a quality model.

First it is important to determine the diameter of the fishing line. It is necessary to select products that are suitable for the grass trimmer. Of course, it is possible to buy a more advanced version, but the quality of the cut is not guaranteed.

The easiest solution is to take your old trimmer fishing line and show it to the sales assistant. If he understands the material, he will suggest several alternative models or the original product. The thickness of execution will be the same, which positively affects the performance of the electric grass grinder.
