How to properly use a brushcutter

gasoline grass trimmer: device, types, working principle

A grass trimmer is a modern gasoline or electric garden tool designed to mow grass and weeds. Today on the market you can find a large number of models with different technical characteristics. A wide range of equipment can confuse not only beginners, but also experienced gardeners. To avoid complications, you need to determine the requirements for the tool in advance, as well as study its main factory parameters. This will give the opportunity to choose the model that will quickly cope with the tasks assigned to it.

The concept of “grass trimmer” is a kind of lawnmower, but more compact and lightweight. This tool is designed for smaller areas and difficult landscapes: with uneven areas, bushes, trees, flowerbeds, buildings, and the paths between them. In such conditions, a full-size mower is inappropriate, and many buyers cannot afford a large unit.

Grass trimmer

Trimmers use cord (string, line for trimmer) to cut grass, for branches. disk with blades or nozzles-blades. Working parts rotate at high speed, so that the sharp ends of the line or the sharpened edges of the discs cut the stems of the plants. The grass clippings are thrown to the left, as the spindle on which the nozzle is attached rotates counterclockwise. Trimmers can be powered by gasoline or electricity.

For your information! Many machines need to be held on weight, but there are models with 2, 3 or 4 wheels.

Popular Questions

How to extend the life of your trimmer?

Wash and clean the trimmer head from dirt and dust after each mowing. Use only high quality fuel (92 or higher) to fill up your brushcutter. When choosing an oil, give preference to the types used for high-speed machinery.

It is necessary to fill the tank with fuel up to the top?

It is not recommended by manufacturers to leave the fuel in the tank after mowing. So first you need to estimate the scale of the work and dilute the oil with gasoline in the right amount. If the fuel is not used up, you can drain it until the next time. It is important to note that the mixture retains its properties for 2 weeks.

What types of trimmers can be repaired?

Household models often exhaust their modest resources, and then are written off. In some cases, you can replace the cover of the head, which is subject to abrasion because of the constant friction of stones and debris.

Semi-professional and professional models can be repaired than to prolong the service life of the equipment. However, when buying, you should consider that the repair of powerful equipment is always more expensive.

What is the maintenance of the grass trimmer?

Clean the tool each time after use. The foam filter should be wetted with oil. If the lawnmower is used frequently, it is necessary to check the fuel filter.

Because of vibrations during operation, the connecting elements are loosened. Do not use a cord or blade that does not belong to the cutting attachment. When replacing the cutting part, it is recommended to use only the line or blade specified by the manufacturer.

The gasoline grasshopper device

The weight of the entire device is about 8 kg, which is quite difficult to hold in hands. That’s why the mower itself comes with an unloading backpack strap with a protective cover and regulators.

grass mower is designed for mowing grass and small bushes in household plots.

As it is known the grass can be mowed in different ways. by either depositing it in swaths or simply mowing. In addition, the grass is different. soft or rough, with thick stems, brushwood.

Trimmer types and construction

Depending on the power source for the engine, grass trimmers are divided into gasoline and electric. The first type is equipped with a tank for fuel and lubrication, the second works on the mains or battery.

Construction of the gasoline grass trimmer

All elements of the unit are mounted on a long metal bar. On its upper end is the gasoline tank, the internal combustion engine and the starter for starting. At the lower end is the spindle, which turns counterclockwise. A spool of fishing line or sharp steel or plastic blades (disk with teeth) is mounted on it. Inside the rod, which is a hollow tube, there is a rigid or flexible shaft, which transmits the rotation from the motor to the working tool.

For your information! If the rod is straight, a rigid shaft is used that connects to the gearbox above the spindle and transmits torque to it from the drive. If the boom is curved, there is no gearbox and a flexible shaft is used.

In the middle of the bar there is a handle-holder, which can be D-shaped or bifurcated, similar to a bicycle handlebar. Asymmetric folding handles (like Husqarna brushcutters) are very useful. Buttons and levers for controlling the trimmer are on the handle or shaft. The motor, control elements, and reel/disc are connected by a flexible cord. The boom comes in one-piece, collapsible, and telescopic models. The length of the last two types can be changed to adjust to the height of a particular person. Some models have fasteners for lap belts. The disc or spool (bobbin) is covered with a shield to protect the person mowing the grass.

Cutting tool is a spool with a trimmer line (cord, string) of 2-3 mm diameter wound around it. In some models, the line for the trimmer is wound with a reserve, and with a light impact on a hard surface, it automatically slides out of the bobbin. In other trimmers, a section of cord is inserted into the spool, and the excess length is cut off against the sharp edge of the shroud.

In addition to the filament, some brushcutters come standard with a sharp-toothed blade. The shape of the teeth can be different. For sawing branches and bushes, use a nozzle-knife or a cutter, similar to the circular saw disk.

For your information! Some trimmer models can be supplemented with other attachments: a brush, a chain saw, a cultivator for the soil.

Gasoline trimmer control

There is a rotary knob on the actuator which moves or closes the air damper. It’s used to start the engine faster, for example, to warm it up when it’s cold outside. Other controls are on the handle-holder or boom of the device:

  • throttle trigger. controls the carburetor choke to change the amount of fuel going into the actuator;
  • stop button. designed to break the ignition circuit, stops the engine
  • button to prevent unintentional pulling of the gas trigger. located under the stop button;
  • Gas trigger lock. Without it, you have to use your finger to hold the starter lever for extended periods of work.

The design of an electric grass trimmer

In general terms, electric trimmers are similar to lawnmowers: the motor, handle, cutting element are attached to the boom.

Side note! The electric motor of the grass trimmer can be top-mounted at the end of the boom or bottom-mounted over the cutting mechanism cover. The second has no gearbox.

You need to plug the power cord into the outlet, so an extension cord is needed for trimming large areas. While the reach of a cordless electric brushcutter is independent of the cord length, the batteries need to be recharged and changed in time.

Instead of the starter, electric trimmers use an on/off button. Unlike their gasoline counterparts, it is not possible to adjust the number of spindle revolutions, so there are significantly fewer control buttons on the device.

As a side note! Both types of trimmers have a cutting width with a fishing line of 22-42 cm. And when using discs or knives, this indicator is directly related to the diameter of the nozzle.

How to mow grass correctly with a trimmer with a fishing line?

Practical garden tools are becoming increasingly popular. With the acquisition of a new helper are inevitable questions, how to properly mow the grass trimmer with a fishing line. To begin with, it’s a great addition to your existing lawnmower. It can be trusted with large areas, and the finishing work will produce a grass trimmer with a fishing line. Let’s clarify, the line for the trimmer is designed to cut weeds and delicate branches. For rougher work, models equipped with metal blades or chain are used.

Safety precautions during work

Technique of work with a trimmer with a string and a disc has some differences. For example, a line for a trimmer cuts the grass at the very end, but if you move too fast, the entire length is involved. The result is that the stems are not cut, but the grass is wound up on the cord, thus overloading the engine. That’s why it’s important to choose the optimum driving speed. In addition, mowing tall and tough grass consumes trimmer line faster than mowing the lawn.

There are a few simple guidelines that make mowing more efficient and effective.

  • A trimmer with an engine at the bottom is convenient for mowing garden paths, flower beds and the edges of lawns. The plane of rotation of the coil of such a device can be positioned perpendicular to the ground.
  • Dense thickets, large weeds, bushes should be mowed with discs or special attachments.
  • When cleaning large areas, the device should be tilted to the left, in the direction of swing.
  • To cut the grass around flower beds, shrubs and other objects, you should turn the grass trimmer head with the hood towards them. That way you can mow the crop without damaging it.

Remember that the spool or disc must not touch the ground or any obstacles other than grass or twigs to be cut.

When working with brushcutters, safety precautions include.

  • You should not use the trimmer in rain or high humidity.
  • People and animals should be at least 15 m away from the working device: grass clippings, small debris and stones fly out from under the cutting head at high speed and can injure.
  • The operator of the grass trimmer is better to wear clothing made of thick fabric, completely covering hands and feet.
  • Wear protective goggles, gloves, hard hat, closed safety shoes and ear defenders.
  • The wire of the grass trimmer’s power cable must be behind the mower.

So, the use of hand-held grass trimmers allows you to maintain order in a small area. On large areas it is more convenient to use a mower. In addition, the grass trimmer is relevant in the preparation of hay and putting in order on the territory: small grass clippings can be mulched strawberries and other useful plants. You can visually see the process of mowing with this tool on the video.

Unlike a disc. mowing with a corded trimmer is safer, but not always optimal. As they say, it is worth choosing a cutting mechanism under the peculiarities of your area of work or use complex systems, where you can operate both the disk and the fishing line for the trimmer, if necessary, setting the first, then the second.

As we have already written, lawn mower with a fishing line can be automatic, semi-automatic and manual. In the first case, the cutting element “ejects” itself after each new start of the machine. This is very convenient, but not economical enough, for example, if your plot is irregularly shaped, and contains corners, jagged edges, and at a long transition to each of these areas the mechanism must be turned off and on again.

It is important for the operator to understand that the length of the line tips that he sees in front of him when stretched out is exactly the diameter that the device will mow. You can read about the rules of threading the line in the spool in one of our articles, but the main thing to remember: the length of the line ends should be optimal to make a competent mowing.

How to mow with a chainsaw? It should be done so that it will serve you as long as possible:

  • Keep the spool 10 cm above the ground;
  • When working with tall grass. mow it at the top, and then at the stem to protect yourself from winding it on the device;
  • Move your machine in the same direction as the spool rotates;
  • Lawn grass, especially near walls and garden décor, is best mowed with the tips of the line so as not to overload the engine;
  • Give the machine a break every 15 minutes.

You will find any answers to your questions about mowers in this section of the site, but we are also happy to offer spare parts for lawn mowers among our other range of gasoline tools.

Ideally tall grass should be mowed with a powerful trimmer and a thick brush line. But agree, the land with weeds is not always smooth, landowners often have bushes and all kinds of debris, stones, etc. In order not to ruin expensive equipment. it is better to mow in two steps.

If you are preparing grass for hay, and you know the condition of the ground more or less, then you can predict your work more accurately. any technique, designed for grass mowing, can also cope with tall bushes. The main thing is not to hurry and competently approach the process, as we demonstrate in the practical video.

  • Do not overload the machine;
  • if the grass gets tangled, turn off the device at once;
  • Do not even mow damp grass with a petrol-powered trimmer.

How to mow grass correctly with a line trimmer?

Practical garden tools are gaining in popularity. With the purchase of a new helper are inevitable questions, how to properly mow the grass with a trimmer with a fishing line. To begin with, it is a great addition to your existing lawnmower. It can be trusted with large areas, and the finish work will produce a grass trimmer with a fishing line. Let’s be clear, the trimmer line is designed to cut weeds and delicate twigs. For rougher work, models equipped with metal blades or chain are used.

The technique of working with a trimmer with a string and a disc has some differences. Thus, the line for the trimmer cuts the grass by the very end, but when moving too fast, the entire length is involved. The result is that the stems are not cut, but the grass gets wrapped around the cord, which overloads the engine. So you need to choose the optimal speed of wiring. In addition, when mowing tall and tough grass, the trimmer line is consumed faster than when mowing the lawn.

There are a few simple recommendations, the implementation of which will make mowing more effective and efficient.

  • Trimmers with a bottom-mounted motor are great for mowing lawns, flowerbeds, and edges of lawns. The rotation plane of the spool of such a device can be positioned perpendicular to the ground.
  • Dense thickets, large weeds, bushes should be mowed with discs or special attachments.
  • When clearing large areas the tool should be tilted to the left, in the direction of the spread.
  • To mow grass around flower beds, shrubs and other objects, you should turn the grass trimmer head with the hood towards them. This way you can mow the objects themselves without damaging them.

Remember, the bobbin or disc must not touch the ground or any obstacles other than grass and twigs that need to be mowed.

Safety precautions when working with brushcutters include.

  • Do not use trimmers in rain or high humidity.
  • Keep people and animals at least 15 m away from the cutting head: grass clippings, small debris and stones fly out from under the cutting head at high speed and can injure people.
  • The grass trimmer operator should wear heavy clothing that completely covers arms and legs.
  • Wear safety glasses, gloves, headwear, closed shoes, special earplugs or ear muffs.
  • The wire of the grass trimmer should be behind the mower.

So, the use of hand-held grass trimmers allows you to maintain order in a small area. Use a mower where there are large areas to be mowed. In addition, the grass trimmer is relevant for making hay and tidying up the territory: small grass clippings can be mulched strawberries and other useful plants. See the cutting process with the skirting tool in the video.

Contrary to the disk. mowing with a cord trimmer is safer, but not always optimal. As they say, it is worth choosing a cutting mechanism under the peculiarities of your area of work, or use integrated systems, where you can operate both the disk and the line for the trimmer, if necessary, setting the first, then the second.

As we have already written, lawn mower with a cord can be automatic, semi-automatic and manual. In the first case, the cutting element is “thrown” itself after each new start of the machine.

What mowing heads to use with a petrol-powered lawnmower

There are two types of cutting nozzles or cutters in the design of chain saws. These are spools of fishing line, as well as steel or plastic discs. What’s the best choice for working with a power tool. The site provides information on how to choose disks and line for trimmers, as well as their types and design features. Let’s briefly consider what types of cutting blades should be used on trimmers and gasoline mowers.

  • A line for a trimmer is used for mowing soft grass, which is wound on a drum or spool. unlike metal discs, trimmer line is used when grass grows near trees, houses, fences, and other obstacles. line for trimmers allows to trim the grass near obstacles, without breaking the construction of the tool
  • Metal blades. have 2, 3, 4 and more cutting parts, through which the mowing of coarse grass and thickets is carried out. Experience shows that the thicker the growth, the more blades of grass the cutter should have
  • Metal discs with fine tines in quantity of 40-80 pieces. designed for mowing different vegetation. It can be rough grass, weeds, dense thickets, and even small trees. The more teeth on the cutting attachment, the more powerful the tool
  • Plastic discs are mostly used on electric or battery-powered trimmers

The choice of rotary cutter depends on where you use the tool. If it is planned to work at the homestead, a line for a trimmer is chosen, and for mowing grass in the field or steppe, discs with 3-4 blades and more are used, as well as discs with fine teeth.

This is interesting!In most cases, the cutters are not complete with the tool, so the buyer can decide for himself what he needs. a line for a trimmer or a steel disc.

How to start a brushcutter correctly

The peculiarity of any machinery with a two-stroke engine is a rigid algorithm of cold starts, which should be strictly followed.Good day dear subscribers and guests of the channel.

The other day a man came to me with a request to look at his mower.

The complaint was that the tool would not start. A client said he bought a mower not long ago, it was used only once. The attempt to start the brushcutter a second time was not successful.

These leakages show that the mower is overfueled, but the user hasn’t used it much, and as I later found out from the customer, they appeared during the failed start-up.

Now everything is in its place. The machine is perfectly serviceable, but the customer would do well to read the instruction manual, especially the section describing the “cold start” procedure.

The result of a proper running-in of the gasoline grass trimmer

After you have been run-in lawnmower according to the instructions, as a result we will get a ready to work tool. Of course, it is best not only to read the steps, but also to see the running-in on the video from the experts. The result of doing the right thing will be:

  • Failure-free operation of the gasoline-powered tool for a long time;
  • quality start-up of the device and stability of the supplied power;
  • No unexpected repairs to the grass trimmer after a good running-in;
  • no overheating.

In this regard, the initial processing of the Chinese grass mower is an integral part of the quality work of the device, which can work flawlessly, using blades for petrol mowers or cutting lines of different diameters when processing areas, available for purchase at the special store “Mower for grass”.

Preparing for the first start of the lawnmower

Before making the first start of the lawnmower, a number of sequential actions must be performed:

We recommend performing them not only when buying a new grass trimmer, but also when preparing the old tool for the new season after storage.

Basic rules and techniques when working with a brushcutter

To get good mowing results and long working life it is important to use and maintain your brushcutter properly. Even if it is the first time you are holding a brushcutter in your hands, you will soon learn the correct mowing technique. The machine is simply rotated in a semi-circle from right to left, moving evenly forward.

Below we show you the basic techniques and tricks with which you can mow even large areas fast and with which you can achieve the best results.

The basic mowing technique is the most frequently used.

Because the cutting attachment is turned anticlockwise, it is more common to mow from the right to the left in working practice.The advantage of this method is that the cuttings drop on to the cut surface.

Big, even surfaces. the right technique.

Large, flat surfaces are best mowed in a square pattern. The square is divided into squares, then you always work along the outside towards the middle.

The basic technique in tall grass.

Mowing in both directions is recommended for very tall grass or tough weeds: You cut the higher part of the grass in one go to the right at first, and the lower part on the opposite side (to the left). Even in this case the grass cuttings are left lying on the left side.

Along a slope. mow after mow.

You will make very good progress by mowing in a straight line, particularly on a slope: cut a swath parallel to the slope, then reverse on the mowed line. Then mow the next higher swath. And here the grass cuttings are always placed on the already cut surface.

Skilfully avoid obstacles. mow playfully.

To mow close to a tree or shrub without damaging limbs or trunks, a string is best. If there are many plants at a small distance from each other, then mowing is suggested before mowing. To do this, use your brushcutter‘s blade guard as a guide. Always guide it exactly along a tree or shrub, and move it around. The trunk remains protected, the area around the trunk will be mowed.

Inspection of lawnmower gearbox and its lubrication

Check the gearbox before starting the gasoline grass trimmer should create a permanent basis. The lack of lubricant or a small amount of it increases the friction of the gear reducer gearing, which operates at a fairly high speed. As a result, the gears overheat as well. Gearbox of a brushcutter fails. To prevent the occurrence of such a failure in the process of use and helps to constant inspection.

If you notice, before starting the gasoline grass trimmer, lack of grease in the gearbox or its absence, put “LITOL” in the housing. To do this, it is necessary to unscrew the screw on the bend of the gear housing and put 1-2 ml of LITOL grease on it.

After every 8 to 10 hours of operation with a gasoline grass trimmer add oil to the gearbox.

Some more tips when working with a brushcutter

Mowing. Hold the grass trimmer head directly over the ground at an angle. The work is performed by the end of the string. Allow the line to run at its own speed. Do not press the trimmer line against the area to be mowed! This overloads the motor and the mowing head. they can fail or melt!

Cutting. The grass trimmer is ideal for cutting grass that is hard to reach with a regular lawnmower. Keep the stringline parallel to the ground during cutting. Avoid pressing the grass trimmer head to the ground, as you could ruin the lawn and damage the tool.

Trimming with a knife. Use a side-to-side reciprocating motion, going from right to left is the working motion, and from left to right is the reciprocating motion. The blade should cut the grass with its left edge (between 8 and 12 on the clock face).

How to run-in lawn mowers and chainsaws correctly.

mechanical. to defend and store gasoline for work not in a metal container and not longer than 1 (one) month, otherwise it oxidizes and loses its properties;

chemical. no admixtures and additives should be present (they have different rates, degrees and temperatures of combustion). Old gasoline turns yellow or red, and the impurities have pungent odors of bitterness (such as creosote) or acid (such as methyl alcohol).

The fuel mix ratio is 1:50 (2%) or 20 ml/cm3 oil to 1 litre of petrol. For example, pour half a measure of gasoline into a clear plastic bottle (1 liter), then use a medical syringe (20 ml/cm3) to inject two-stroke oil and mix it, pour the gasoline and mix it thoroughly. If the quality of the petrol is doubtful or the working conditions are difficult, you can increase the amount of oil to 22-25 ml/cm3. Shake mixture before each filling! Store the fuel for no more than two weeks! If the mixture has changed color (from aquamarine to brown, for example), you should not use it!

Let’s start the lawnmower’s running-in period

After start-up, do not rush to run the grass trimmer immediately. Allow the engine to warm up for about 5 minutes at idle speed. While the engine is warming up adjust the air supply with the choke knob so that the filament bobbin or blade does not rotate. Once the tool is warmed up, open the air supply by moving the lever to the “ON” position and squeeze the throttle trigger to 1/2 and hold for 20 30 seconds. Then we drop the throttle and let the trimmer work at idle for 30-40 seconds. Keep it like that for about 10-15 minutes. Then turn off the engine and let it rest for 15 to 20 minutes.

After the lawnmower has cooled down, continue running in the engine according to the previous scheme. Start the grass trimmer when it is hot, with the air shutter already open. Try not to hold the gas for a long time, because moving parts of the tool only rub against each other. Do not let the engine idle for a long time because it can overheat.

The next step is the running-in of the reducer of the gasoline grasshopper. You should choose an area with soft young grass. Mow for 510 minutes with 1/22/3 of full throttle. After that, take a break for 20 to 25 minutes. Repeat the cycle 34 times.

Generally using described lawnmower in accordance with described algorithm is made until fuel mixture in the tank is completely used up. After that the tool is ready to work for a long time. Monitor the temperature of the gearbox and motor during operation. They should not overheat.

Servicing your brushcutter (grass trimmer)

Engine. Always keep the air filter clean (no dirt or sawdust); oil the foam filter. Check the fuel filter once a week and replace it if necessary if the tool is used a lot. Check nuts and screws for tightness. before starting work. Clean the muffler (or muffler gauze) and plugs as necessary.

Cutting blades. Correctly and carefully sharpen cutting edges by means of appropriate templates and files (emery boards), observing cutting angles depending on the type of blade. The double-sided discs must be turned 180° at regular intervals and worn evenly. A dull disc or a disc that has been badly or improperly sharpened cuts poorly and thus overloads the motor and speeds up the loss of motor service life.

Trimmer lines and trimmer heads. Only use mower line specially designed for trimmers. do not use wire or metal ropes! You should only use a line of the same size as recommended by the hedge trimmer manufacturer. Winding the bobbin tightly but not overlapping the coils. Keep the brushcutter head clean and lubricated as needed. A worn or deformed brushcutter head may damage the gearbox and/or shaft of your brushcutter.

Angle Gearbox. Clean off dirt as needed (this “fur” prevents proper cooling of the gearbox) and apply Husqvarna or similar grease to the gearbox couple.

Protective guards. Never operate the brushcutter without its protective guard. It is a danger to life and limb and may overload the brushcutter engine. You should use only one protective cover for each type of cutting attachment provided by the manufacturer.

To repair your brushcutter by yourself

It should be noted that it is not always possible to repair your brushcutter yourself, but in most cases, small repairs are within everyone’s power.

If the grass trimmer motor has broken, and you are not an auto mechanic or electrician, it is better not to try to repair the mechanism. There is a chance that you will not be able to assemble it back. The following problems are possible: low compression in the engine, the engine is jammed or the carburetor is defective. If these words do not tell you anything, you should not repair brushcutters by picture and intuition.

It should be noted that the maintenance and repair of a chainsaw and brushcutter are similar in many ways.

the grass trimmer consists of a pole, a motor (it can be on top or underneath), and a mowing head with blades, various additional elements. What can be repaired by yourself?

air damper; 2. handle; 3. motor stop device; 4. throttle control lever;

limiting bracket; 6. boom; 7. cutting head protection device;

1) If the rocker switch is defective, you know how to read simple circuit diagrams, a soldering iron, linoleum jelly and solder, you can easily replace the rocker switch with a new one. They are sold in electrical stores and lighting equipment.

2) If the wire stop has fallen off the mowing head, you can wrap it with flexible copper or aluminum wire to the boom. You can also make a new attachment out of a strip of stainless steel.

3) If the trimmer line breaks in the cutter head reel, nothing is easier than replacing it yourself. You can of course just buy a brushcutter head separately and replace it, but trimmer lines are a hundred percent cheaper. The optimum material here is a 0.9 to 1.5 mm trimmer line, nylon or kapron. Measure the diameter of the line you are using right away, before it runs out completely. Thinner may tear, thicker causes motor overheating and unnecessary vibration. You must disassemble the reel and wind the trimmer line by hand, then reassemble the reel.

4) If a rod breaks, it can also be repaired by taping or gluing it to wooden strips or iron staples.

5) If the engine is starting to vibrate and is running rough, you may need to lubricate your brushcutter. Each trimmer is easy to dismantle and should be oiled at least once a year.

7) If the grass trimmer is equipped with plastic knives, and they are deformed for some reason, there is a way to replace them with metal ones. To do this, you need to make a few blades of stainless steel. It may be difficult to do this at home, but you can do it with a turner you know at an industrial facility or a factory. The blades are attached to the shaft with a sleeve with a washer. This improvement leads to the fact that the trimmer will be able to mow grass of any hardness. But caution when handling such a trimmer is worthwhile.

8) The engine does not start? In order to start the engine, sometimes even when it’s hot, you need to close the choke completely to enrich the mixture. Check gasoline intake, clean, replace glow plug if necessary.
