How to mow grass with knives

The blades (disc) perform well when working with hard grass or bushes, but there are some safety rules you need to follow. Here are the main points to remember when using knives:

  • Knives suitable for cutting tough grass, young trees or bushes.
  • The more difficult the task, the larger the diameter of the disc with knives should be.
  • Only fit discs to the trimmer with dimensions that match the capabilities of the tool. Otherwise, the trimmer may break.
  • If the tool is turned on, it can only mow, but not replace the consumable, lubricate or inspect the petrol trimmer.
  • Select discs based on the information on the disc and follow the manufacturer’s instructions.
  • Do not sharpen the knives yourself, this may ruin the part.

Instructions and rules for working with a lawn mower

A garden trimmer is a very useful piece of equipment for anyone who has their own plot. Garden trimmers are also called lawn mowers. They are gasoline and electric. Caring for electric grass trimmers is very simple, but gasoline owners need to know a lot of nuances. In this article we will tell you in detail how to start the trimmer, run it in, as well as how to properly mow the grass with it.

How to cut grass with fishing line

Mowing with a trimmer that has a line or line is safer than using knives. However, the work efficiency will be lower. It is better to always select consumables for specific tasks and combine their use.

When working with a gasoline trimmer that has a line installed, follow these tips:

  • mow at a height of about 10 cm above the ground;
  • first mow the upper part of the grass, and then cut off the stem at the base. this will help to avoid winding on the working part;
  • it is better to drive the unit in the same direction in which the coil rotates;
  • when mowing the lawn, it is better to work with the ends of the line to reduce the load on the engine;
  • every 15 minutes of operation, you need to give the gas trimmer a rest.

At idle speed

It happens that the lawn mower stalls after some time after starting. The reasons may be:

  • incorrectly adjusted carburetor;
  • contamination of the carburetor, filter or throttle valve;
  • air in the carburetor system;
  • malfunction in the ignition system;
  • lack of gasoline.

Why the lawn mower stalls?

Depending on at what point the trimmer stalls, the reasons may be different.

Fuel mixture

Before you start running in the engine of your new lawn mowers, you need to prepare a high-quality fuel mixture. Lawn mowers with a two-stroke engine will need the appropriate oil and gasoline. They need to be mixed in a certain proportion, which you can find out in the instructions for the trimmer. The manual also contains information about the fuel and oil recommended for a particular model.

Do not prepare fuel with a margin, calculate the amount that is enough for one mowing. Fit a plastic canister for fuel. A glass or metal container will also work. To draw oil conveniently, you need an ordinary syringe.

Often, tool and oil manufacturers indicate different proportions, so owners of gasoline trimmers do not know which one to choose. Often in the instructions for the trimmer, a ratio of 1:25 is indicated, and in the instructions for the oil. up to 1:50. Which one will be better?

Experts believe that if the trimmer instructions indicate a ratio of 1:25 or 1:30, the manufacturer simply does not know which oil will be used. Too much oil damages the tool because it does not burn out completely, leaving a small amount of coke that then clogs the engine parts. It is better to give preference to the proportion recommended by the oil manufacturer.

Before you start working with your lawn mower, there are a few steps you need to take to get the tool ready for use.

How to choose a line for lawn mowers, trimmers

Choosing the right thickness and shape for the right line can sometimes be a real challenge for trimmer owners or lawn mowers. Below we will try to explain how to choose the right fishing line.

There are two most common line shapes: round and rectangular. Each is suitable for a different purpose. The round shape of the fishing line is intended for mowing grass near curbs, trees and where it is likely that, in addition to grass, it will come into contact with hard objects (small tree branches, for example), thereby the wear resistance indicator will be negative. Angled line and its profile are more suitable for mowing. Its sharp corners cut the grass better. But as a rule, such a line is a little more expensive, and in contact with hard objects it will also wear out like a round one, based on this, the cost of cutting will increase.

CUTTING LINE MATERIAL:

Vendors usually offer fishing line made of different materials, it is color-coded and for a comfortable mowing you will be quite satisfied with the average quality of the line. Basically, people buy the cheapest option, but the cheap line tends to break and wear off quickly.

CUTTING LINE THICKNESS:

Naturally, everyone would like to use thick line, but the ideal diameter should be specified in accordance with the characteristics of the particular lawn mower (trimmer) on which the line will be used.

LINE THICKNESS FOR SMALL ELECTRIC TRIMMERS:

For small trimmers with a power of about 450 W and the location of the electric motor in the lower part of the trimmer. the cutting head, it is better to use a line with a diameter of 1.3 mm. If the trimmer has a torque limiter, 1.6mm line can be used, but there is a significant possibility of trimmer overheating. With such a line, the trimmer should mow no more than 10-15 minutes. After that, the trimmer should run idle, and then you need to turn it off for 15 minutes.

THICKNESS OF THE LINE FOR POWERFUL ELECTRIC TRIMMERS:

For more powerful electric trimmers from 600 W, which have an electric motor in the upper part of the trimmer. the handle, a line diameter of 1.6 mm is used. For power over 1000 W, a 2 mm line can be used. You can mow for a longer time with these trimmers. Also powerful models can be used for mowing larger areas.

THICKNESS OF LINE FOR lawn mowers:

For lawn mowers, a fishing line with a diameter of 2 mm or more is used. In the characteristics of lawn mowers, as a rule, the maximum line diameter is indicated. lawn mowers are more powerful than electric trimmers and are designed for large areas.

THICKNESS OF THE LINE FOR DIFFERENT TYPES OF MOTOR HEAD (SPOOL):

Mowing heads (spools) are divided into three classes: hobby, semi-professional and professional. For cheaper mowing heads, fishing line with a diameter of up to 2.5 mm is used, and for semi-professional middle class. up to 2.7 mm, and 3 mm for professional expensive mowing heads (spools). The thicker the line, the faster the mowing head wears out and breaks, and the line jams in the mowing head.

Sectional shape

The most often chosen line for electric scythes with a round cross-section. It is inexpensive and the most popular, it mows fresh grass well. Its main drawback is the noise level that is heard when the trimmer is in operation. Line noise is similar in intensity to engine hum. For the best noise reduction, manufacturers suggest using a spiral-shaped line.

Today they also produce square trimmer line. Of other forms, rectangular and star-shaped are quite often found. Lines with jagged edges and sharp edges are especially productive. These edges cut the grass more evenly.

There are also lines with notches and dents. They can mow large weeds. The noise level emitted by such a line is low, and due to the increased properties of aerodynamics, the trimmer is given additional power. Such a cutting element is installed on powerful trimmers, with which it is planned to carry out work on overgrown, neglected areas.

To work with this type of fishing line, special heads are installed on the lawn mower. The fishing line is wound on them. It handles all kinds of grasses (especially weeds) and shrubs. But its cost is quite high. The consumption of such a line is also high, since when it is fed from the reel, it can be difficult to extract it. It is usually used with discs, into which it is inserted in small sections.

There is also a two-piece twisted trimmer line. Its purpose is high-quality mowing of dead wood. It is distinguished by its round cross-section, tear resistance and increased strength. It comes with a core made from a different material. The twisted line is only suitable for petrol trimmers. She is able to cope even with small shrubs. Its main drawback is its high cost. For daily work, it is quite expensive to acquire a twisted line.

How and which line to choose for a trimmer

People who work in the country may need a trimmer, however, not everyone knows what it is, how to choose a line for a trimmer, and what it is for. A trimmer is a device that allows you to carefully cut grass near trees, fences, paths. The operation of the device depends on the type of equipment, which is often used as a cutting line. It affects not only the external condition of the lawn, but also the performance of the trimmer. The main requirements are that it must bend, have strength and rigidity.

  • The main parameters of the trimmer line
  • Thread thickness
  • Sectional shape
  • Line composition
  • Line selection for the lawn mower
  • What nuances should be observed when working

The main parameters of the trimmer line

Fishing lines can be classified according to the following parameters:

  • Thread thickness;
  • Sectional shape;
  • Line composition.

Line composition

It is the composition that determines the service life of the line. It is often made from nylon. It wears out slowly and improves performance efficiency at high temperatures and heavy loads. The material retains its working properties for a long time, low temperatures do not affect it, as well as prolonged work.

Coaxial trimmer line is considered one of the strongest. It has a dense core, and therefore wears out gradually. Such a line is difficult to cut with a knife and creates little noise during operation. Also now there is a fishing line, which includes inclusions of aluminum.

Line selection for the lawn mower

What line to choose for a trimmer is thought by each of its owners. It should be chosen based on the following parameters:

  • The diameter of the trimmer line must be suitable for the engine power. In terms of parameters, it should be combined with the trimmer option.
  • The type of line should be chosen based on the type of vegetation to be cut. If you plan to mow the lawn, a thin line is suitable, for the destruction of perennial weeds. a thicker one.

Thread thickness

You can find out about it by reading the performance of the trimmer or by referring to the dimensions and inscriptions on the universal bobbin. Typically, for trimmers, threads with a diameter of 1.2-4 mm are used. True, for each device you will have to select a line of a certain diameter.

The trimmer thread, thinner than the required one, will not immediately disable the engine, although it will significantly increase its wear. If you use a thread that is thicker than necessary, the resistance to rotation will increase, the motor will work harder, overheat and, as a result, break. True, a lot depends on the engine itself.

You can also find out the approximate diameter of the fishing line for the device by the type of engine. If the trimmer is powered by electricity or a battery and its power is 1 kW, you will need a cutting thread with a diameter of 2 mm, and if its power is less than 500 W, use a line of no more than 1.6 mm.

For a gasoline trimmer, the line is chosen with a certain diameter. 2.4. 3 mm. The choice of such a thick fishing line is associated with the peculiarities of gasoline units. they are more powerful and more efficient than their electric counterparts. Thick line can be used for a long time, in addition, it can easily overcome long-term dead wood.

What nuances should be observed when working

When treating a lawn with a trimmer, it is necessary to avoid contact of the line with rigid elements, such as stones, trees, foundation. Contact with them will lead to grinding of the fishing line, and you will have to constantly increase it in length.

The main cutting element of lawn mowers is a reel equipped with a lawn mowing line. Its price is low, and if you follow the basic rules of use, it will last long enough. Today there are fishing lines that differ in their quality, section, properties. The line is usually sold in regular rolls in spools, or cut into lengths for certain lawnmower models. Therefore, take full responsibility for its choice in order to make it easier for yourself and extend the life of the trimmer.

Trimmer head modification

Trimmer mowing heads can be of various modifications: single-line for trimming the lawn (mows with one line of fishing line); two-string for mowing grass and land clearing with automatic line feed or manual string length adjustment.

Modern growers are increasingly offering gardeners universal trimmers with two-line automatic mowing heads.

Short introduction

To begin with, it must be said that knives or fishing line can be used as a cutting element in trimmers. Both types have their advantages and disadvantages.

So, knives do a much better job with shrubs and dry wheat grass, but polymer thread is much cheaper and more affordable. In addition, the 4 mm trimmer line also allows you to cut fairly tough grass. Of course, it cannot be compared with a knife, but the efficiency is also not bad.

Note that even in the latter case, you need to know exactly what its diameter is used in your trimmer. Manufacturers do not take all the values ​​from the ceiling: if you take a larger line, then you will greatly overload the engine, which may well cause the latter to fail.

Line selection

In order for the trimmer to work “like a clock”, it is necessary to choose the right line, that is, choose it taking into account the trimmer model and the type of work. There are two important parameters in this matter. this is the diameter and section.

The diameter of the fishing line must correspond to that recommended for this model (it must be specified in the product passport).
The cross-section of the fishing line is round, square, with sharp edges (pentahedron). A round line is designed for mowing young grass and lawn, square and pentagonal line will come in handy if the grass is coarse and weeds have grown on the lawns.

We will learn how to properly tuck the line into the trimmer

But beginners rarely know about even the most basic rules for caring for this technique. So, the most common question is how to properly tuck the line into the trimmer.

How to properly install the line on your lawn mower

Step-by-step instructions for threading the line into the trimmer

  • Press the clips inward until they click and remove the cover from the mowing head.
  • Turn the spool carefully, it will free itself from the holder, and now remove it.
  • Cut two identical pieces of line (the edge of the line should be cut at an angle. This will make the job easier). Take one of them and insert the end of the line into a special on the reel (there may be hooks, ears, clips). Then wind the string in the direction of the arrows. Spread the line evenly, tightly. Attach the end of the string to the specially provided hole in the reel.
  • Do the same operation with the second part of the line, only thread the end on the spool from the opposite side.
  • Return the line spool to the mowing head. Pull out the ends of the line through the holes in the spool and thread them into the special connector of the head.
  • Spread out the line carefully and close the lid. Cut off excess fishing line, leaving 12-15 cm at each edge.

All is ready. The trimmer is loaded with line and ready to go. Now you can happily start mowing your favorite meadow, summer cottage, local area.

It is only important to remember that not only the quality of the work performed, but also your safety will depend on how you load the cutting line into the trimmer.

Video instruction for refueling the benzotrimmer line (lawn mowers)

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 between the line winding in two-groove spools is that initially a 2-5 m long line segment is folded in half (to determine the middle bend), and the bend 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 trimmer spool and wind it correctly. this operation is not difficult and with some patience it will certainly be crowned with success:

After the cutting thread has worn out as a result of the work, turn off the scythe and remove the cover on the mowing head. Pull the wood out of the slot by pulling it to the desired length and reinsert it into the slots. The amount of material wound on a reel is enough for 5-10 work cycles, depending on the model of the device. When you put the cover back in place, carefully look if the grooves where the latches are inserted are not clogged, if they are clogged, then carefully clean them.

When the line is worn out, you need to disassemble the mowing head again, pull out the spool and rewind the line on it.

The trimmer is the most common machine used for cutting grass and small bushes. This device is distinguished by its simplicity in service, simple operation during operation, and due to its low weight, even women can handle it. It is no secret that for high-quality performance of work on mowing grass, the correct selection of cutting tools is required. As the latter, special cutting attachments (discs, knives) or trimmer heads with a fishing line inside are used in trimmers. Nozzles and fishing line are consumable tools, but if the knives can be sharpened, then when the line is used up, it must be replaced. In this article, we will tell you in as much detail as possible how to properly replace the fishing line.

Which line to choose

Before you stock up on this material for refueling in the 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 with sharp edges. Usually they are made with an asterisk or a square. The presence of sharp edges is the main feature and key difference of these threads.

It is due to this feature that threads of these types are able to mow dry weeds. But sharp-cut threads are not without drawbacks, the main of which can be called rapid 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.

Trimmer coil device

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

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

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

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

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

Materials:

  • 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 point of view
, hacksaw blades should not be completely hardened.

Everything you need to make a nozzle

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

First you need to make the base of the nozzle. For this from a metal plate

cut out a square with a side of 100 mm. 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.

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

Round off the corners and drill the center hole for the trimmer shaft

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 trimmer attachment are prepared, 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 trimmer shaft. This is followed by a large washer and a nut that is not tightened so that the knife rotates freely. We attach the other 3 knives in the same way.

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 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.

DIY trimmer coil repair: how to remove, disassemble, change the line, assemble and install back

The cord lengthens spontaneously

There are times when the trimmer user notices a very fast line flow. However, he never hit the ground with a button to lengthen the line. The reason for the fact that the line spontaneously lengthens, being cut on a special knife on the casing of the device, may be the absence of a spring in the mowing head. Often novice users of mowers, trying to load the line into the reel, forget to install the pressure spring in the head, or even lose it when opening the lid, and in the future, do not even suspect of its existence.

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

Line does not extend automatically

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

Option 1. a bite has occurred, i.e. clamping the cord between turns. This problem usually occurs if the user has been winding the line on the reel unevenly, with intersecting turns, or winding it with insufficient tension. In the latter case, when the mowing head rotates at high speeds under the influence of centrifugal force, the cord begins to tighten, as a result of which inter-turn clamping of the fishing line is possible. To fix the problem, you will have to disassemble the coil on the trimmer and rewind the cord correctly, that is, in even turns with good tension.

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

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

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

Thickness selection

In addition, you should pay special attention to the thickness of the consumable. For mowing young grass, a thread with a diameter of one and a half millimeters is suitable. The larger the diameter of the thread, the more dry and coarse weeds it is capable of overpowering.

When choosing a fishing line by thickness, there is one “but”. It is important not only to assess the capabilities of the material, but also to take into account the features of the trimmer. Be sure to check the user manual that came with your tool for information on cutting element requirements.

Using the wrong thread can damage the tool. Using a thread that is too thick will overload the machine’s motor. And the use of a thread that is too thin will significantly increase the wear of the twisting mechanism.

That is why it is necessary to approach the choice of consumables no less responsibly than to refuel it in the trimmer. When a suitable fishing line is found and purchased, you can begin to consider ways of winding it on a reel.

Assembling the starter lawn mowers

When servicing and repairing the starter, it is important to assemble it correctly. as if the assembly was carried out by the manufacturer. Any part that is incorrectly installed will prevent you from fully using your trimmer or lawn mower.

  • After winding the spring, turn the coil over and place it so that the second spring hook falls back into place. To control the correct installation of the spring, there are technological windows on the coil itself.
  • Install the starter pulley and make sure that one of the spring hooks fits into the groove located on the starter cover.
  • Insert the spring and washers on the sides to prevent the spring from rubbing off the plastic compartment in which it is located. If the spring is broken, but the other is not the same, an additional washer is placed in its place.
  • Insert the cup with antennae into the slots of the coil.
  • Install the coil in its place, tighten the bolt until it stops, but without fanaticism.

If you do not shield the mainspring with washers from the compartment where it moves when winding and unwinding the starter cord, the reel will often jam when you try to start the trimmer or lawn mower. Loosening the coil bolt will result in its loss.

How to assemble a lawn mower trimmer starter, watch the video.

How tight the spring is cocking?

It is possible to give the spring the necessary potential force necessary for a clear and quick winding of the cord, by determining the length of the cord in turns. To prevent the cord handle from drooping, add 1-2 more turns to the number of turns. So, if the cord has a length of 5 turns of the coil, then when charging the spring, turn the coil 6-7 full turns.

How to replace or replace the starter spring?

If everything is in order with the rope on the starter, suspicion falls on the reel itself. It is driven by a ribbon spring, coiled into a roll. To change the spring, certain steps must be taken.

  • Remove the starter from the lawn mower.
  • Remove the starter coil.
  • Unscrew the main bolt holding the pulley to the housing.
  • Pull out the gripping tendrils and spring, the ribbon spring is almost fully extended or coiled into larger diameter rings.
  • Hold it in advance.
  • Check if the spring is intact (rusty streaks, fractures, etc. may be present). If the hooks at its ends are torn off, it will not be possible to bend new ones. high-carbon steel breaks when you try to bend it. Loose hooks are suitable for slight bending.
  • Make sure the auxiliary (regular) spring and washers are in place. These parts protect the coil body from being punctured by the ends of the main spring. If the washers and spring are broken, and new ones are not available, do not tighten the coil bolt tightly, but watch it. it can unscrew and get lost.
  • If the main (flat) spring is damaged, insert the same new one. Place the hook on the end of the spring in its place and bend it, inserting coil after coil into the space where it should be.

How does the starter for lawn mowers or trimmers work??

The starter is a generally single and universal mechanism for lawn mowers, trimmers, gasoline and diesel generator sets. It is not a problem to equip them even a car, motorcycle or scooter, if your vehicle has free space for its installation. It was not for nothing that many Soviet cars and trucks were equipped with a starter tool that remotely resembles a crowbar bent twice.

The modern “handbrake” starts exactly from the cord. it is tied to the mechanism, and it is impossible to lose it.

The starter assembly has the following parts:

  • hook ignition spring;
  • cord wound on a reel;
  • return spring;
  • ratchet drive and main spring;
  • mechanism housing protecting the ratchet;
  • locking bolt.

The recoil starter for a lawn mower or petrol trimmer is a mechanical unit that includes a pulley fitted to a ratchet. A rope is wound on the pulley in the initial position. At the start, it is pulled outward. The pulley is spring loaded. as soon as you let go of the end of the rope, it will reel back. A flat tape rolled into a ring is used as a spring. It resembles a spring in a large mechanical watch that is wound once a day. The starter itself is located more often at the rear than closer to the front end of the mower or trimmer. To correctly perform all manipulations with the starter for lawn mowers, you need to know the features of the device and installation.

Worst case of failure

There are times when the starter is still operational, but a worn out cord can break, for example. The ratchet has not yet had time to work when the engine is started, and the remnants of the cord are immediately wound on the reel, the return spring loses its hooks, the grooves in the starter housing break. The result is the replacement of both the springs and the housing.

If a lawn mower or trimmer model has long been discontinued, it will be difficult to find exactly the same parts, and the starter is changed entirely.

How to assemble a new lawn mower starter?

To assemble the starter, do the following manipulations.

  • Pass one end of the cord through the opening at the beginning of the spool and tie it in a knot. The knot must not pass through the hole. Otherwise, you will disassemble the starter again.
  • Wind the cord onto the spool itself.
  • Install the spring into the starter housing, hook one end of it in the groove and wind it. For convenient winding, twist the body counterclockwise.
  • Place the ratchet on the spring.
  • Hook the return spring to the ratchet itself, attach it to the spool.
  • Install the main spring and housing with the assembled ratchet, connect the parts of the starter together and tighten everything with the main bolt.

After assembling the starter, pass the free end of the cord through the hole in the housing for the reel. Re-pass the same end through the hole in the handle that the cord is pulling on. Tie a strong knot on the handle. Check the operation of the starter handbrake.

How to change the starter cord?

It happens that it is not the spring that is to blame for the inability to start the starter, but the cord itself. It can seize or even break. Disassembling the starter of the lawn mower or trimmer is versatile in its steps.

  • Remove starter block from trimmer or lawn mowers.
  • Remove the main bolt holding the handbrake.
  • Pull out the spool and rewind the remnants of the worn out cord from it.
  • Untie the knot on the cord handle and pull the end out of it.
  • Untie the knot at the other end (at the beginning of the spool) and remove the old cord. Knots that have become tight are untied with pliers or pliers.
  • Tie a knot at one end of the new cord, pass it through the hole at the beginning of the spool (closer to its axis).
  • Wind a few turns of the new cord onto the spool. If it is long, then cut off the excess.
  • Load and charge the spring-loaded cord tensioner (if removed) and spring-loaded elements in the correct sequence.
  • Replace the spool and thread the free end of the cord through the starter outlet and handle.
  • Reinstall the starter block.

Twist the starter by the cord, start the engine on lawn mowers or trimmers. The larger and more powerful the engine, the more jerks of the cord will be required at startup, the norm is no more than 7 times. The result is a quick and smooth start of the motor, the readiness of the unit for operation.

What can be put instead of fishing line on a lawn mower and a petrol trimmer

If it turns out that there is no special trimmer line at hand, then you can use the most common fishing line. Usually they take a fishing line with a diameter of 2 mm, but you can try to put a fishing line and thicker.

The only thing you will have to face in this case is the difficulty of winding the line. The fishing line is too soft, so everything here largely depends on the design of the reel. If the line has to be wound, then this should be done in a small piece.

It is much easier to install fishing line on the trimmer, in the case when its reel is not wound (just thread the desired piece of line or cable through the hole, and then snap the reel).

What to put on the lawnmower instead of fishing line

Very often, trimmer owners and lawn mowers want to increase the productivity of these garden tools. This is due to the fact that when purchasing a lawn mower, few people think about the power, the radius of the grass bevel, and other equally important characteristics.

Having acquired a tool, many face difficulties when mowing small bushes and tall grass. Therefore, the question of what can be put on the trimmer instead of fishing line is more relevant than ever.

In principle, a slightly larger diameter line can be installed on the trimmer and lawn mower than the one recommended by the manufacturer. You can also try to use a steel cable for these purposes, but here you need to be extremely careful, and additionally fix it.

Even the slightest bounce of a stone towards the operator or others from the cable (or a piece of the cable itself) can lead to unpleasant consequences, such as injury. What else can be used instead of fishing line on the benzotrimmer?

Can I use a cable instead of a line on the trimmer

Of course you can. However, at the same time, it is worthwhile to understand all the insecurity of this venture, and the ultra-fast failure of the transmission of the petrol trimmer. Indeed, a steel cable is a hundred times stronger than a fishing line, even a special trimmer. It will not tear as often from grass, branches and stones, so it will last much longer.

At the same time, you need to understand that the line breaks when the trimmer is working not just like that, but from a strong load. As a result, the lawn mower engine does not stall, while dynamic shocks to the mower transmission are absorbed. In the case of a steel cable, the entire load will fall on the transmission, as a result of which it will quickly fail.

If you really want to try using a cable on a lawn mower, then at least you need to install it correctly. First, you must not wind a long rope around the reel. Make it so long that it does not interfere with the trimmer guard when the spool rotates.

Be sure to clamp the cable with washers in the middle and place one drop of welding at its ends so that it does not bloom. As a result, the cable should not have any protrusion, and welding at the ends will protect it from unraveling. However, even this way, it is very unsafe to use the cable on a lawn mower or trimmer. It is much easier to use ready-made factory nozzles.
