At what engine rpm to mow with a brushcutter

How to work correctly with a brushcutter (trimmer)

Working principle and design of brushcutters is not very different from any other small gasoline gardening equipment, for example, chain saw, brush cutter or hedge trimmer. The brushcutter is basically a single-cylinder, 2-stroke carburettor-based gasoline engine (four-stroke less often), a manual starter and an air-cooling system. the engine runs on a fuel mixture of petrol and 2-stroke motor oil in the ratio of 1:50. The proportion of the fuel mixture may vary from the standard, depending on the individual recommendations of the manufacturer, specified in the instruction manual of the product. Always observe the recommended proportion. The cutting attachment for the brushcutter is the mowing drum with the line or the metal cutting blade, the saw. The engine revolutions are transferred to the mowing headset as follows: crankshaft. clutch. clutch plate. drive shaft. bevel gear. mowing head (blade).

For good mowing results and long service life it is important to use and look after your brushcutter properly. Even if this is the first time you are holding a brushcutter you will soon get the hang of correct mowing techniques. You simply turn the machine from right to left in a semicircle, gradually moving forward.Below we show you the basic technique and some tricks with which you can mow even large areas quickly and get the best out of your mowing.

The basic mowing technique. Most common.

Since the cutting tool rotates counterclockwise, the mowing motion from right to left is most common in working practice.The advantage of this method is that the cuttings drop on to the already mown area.

Large, flat surfaces. The right technique.

It is best to mow large, even surfaces using the square head method. The area is squared, then you always work along the outside towards the center.

The basic technique in case of tall grass.

In the case of very high grass or stiff weeds it is recommended to mow in both directions of movement: first you cut the upper part of the mowed grass in one movement to the right, with a counter-movement (to the left). lower. Even then the cuttings remain on the left side.

Along a slope. mow after mow.

You will make good progress using the straight swath method especially on a slope: cut one swath parallel to the slope and then go back along the mowed swath. Then mow the next higher swath. And here the grass cuttings are always placed on the already cut surface.

Masterfully go around obstacles. Mowing with play.

To mow close to trees or shrubs without damaging limbs or trunks, a string trimmer is best. If many plants are a short distance apart, mowing is suggested here before mowing. Use your brushcutter’s blade guard as a guide. Lead it all the time directly along the trunk of the tree or shrub, and move around them. The trunk will remain protected and the area around the trunk will be mowed.

A few more tips when working with a brushcutter

Cutting. Hold the grass trimmer head directly over the ground at an angle. The end of the stringline does the job. Allow the string to work at its own speed. Do not press the trimmer line against the area to be mowed! Doing so overloads the motor and the mowing head. they can malfunction or melt! Cutting. The grass trimmer is ideal for cutting grass that is difficult to reach with a conventional lawnmower. Keep the string parallel to the ground while cutting. Avoid pressing the grass trimmer head against the ground, as you could damage the lawn and damage the tool. Pruning with a knife. Mow in a pendulum motion from side to side, right to left is the working motion, and left to right is the reciprocating motion. The blade should cut the grass with its left edge (on the clock face. between 8 and 12).

Cutting the grass

Purpose of trimmer head (grass trimmer reel, mowing head, grass trimmer bobbin)

To remove all unwanted vegetation under walls, along fences, curbs, around trees, posts, bushes, between stumps and other obstacles.
To cut the grass in places not accessible to the lawnmower.
To selectively cut through loose grass and weeds before mowing a yard for hay.
To cut weeds in the bed between plants.
To cut potato foliage in the vegetable garden before digging it up.
To remove grass and weeds completely, e.g. from paths.
To sweep (creates an air vortex from the grass trimmer’s large line revolutions).

Note

A trimmer head (mowing head or grass trimmer reel) has a high output when it mows grass, t.к. it is lighter for the metal blade and has a larger grip diameter. 45 cm, compared to 25 cm for the hay blade.

Variety of tools

There are three versions of garden trimmers available. electric, battery-powered, and gasoline-powered. Network models, plugged into the socket, are less common, as they have minimal opportunities for autonomous work due to the binding to the power grid. Also, in terms of economy, it is not the best grass trimmer for mowing. An electric lawn mower is worth operating on sites around the house if extension cords can be connected.

Potential for churning flying rocks puts windows at risk in homes and on cars. Shields around the trimmer head are in place to reduce flying debris and protect the operator. no one removes the shields after the modified grass trimmer is no longer under warranty or can be used safely.

When re-filling, make sure the engine is stopped and the grass trimmer is placed on a level, level surface. preferably not a grass. The grass trimmer should never be left on the grass for long periods of time. Refill with the proper system to avoid leaks or overfilling.

Gasoline modifications have always been considered a direct competitor to electric models. They provide high power, virtually limitless movement, and handle even shrub cutting. But, gasoline grass trimmer for mowing the grass is also characterized by high weight, noisy operation, strong vibrations, exhaust emissions and high cost. Cordless versions aren’t tied to a power source either, but they lose out to gasoline trimmers in terms of power.

Be sure to use the appropriate string weight as indicated in the owner’s manual. A grass trimmer string that is too thick for the engine can cause damage. Some grass trimmers can accept a trimming blade, but never use a blade on a trimmer that is not designed to use trimming blades. Accessories that are not designed for a particular grass trimmer can create excessive vibration, engine wear or binding. This can lead to motor strain, possible component failure and potential damage to the operator.

How to mow grass correctly with a garden trimmer

Working with a brushcutter is easy enough if you know the basics and have a little practice. Here are a few tips to help you get a good result and keep your lawn well groomed:

If you need to cut tall grass or weeds with strong stems, mow in double strokes. First cut the top of the stems by moving the scythe from right to left, then mow everything else by moving in the opposite direction.
If you need to mow a large area, divide the area into squares, starting on the outer sides and gradually moving toward the center.
Work on slopes according to the following algorithm: start at the bottom, cutting the grass in parallel lines and gradually climbing upwards. Grass will fall down into the cut, not interfering with your work.
If you want to mow around an obstacle, consider the protection of the chain saw. Move around the obstacle, gently driving around it with the tool.
Always install only quality attachments on your gasoline grass trimmer. When working with a fishing line or low-quality blades, the grass may not be cut, but uprooted. the lawn will quickly fall into disrepair.

How to mow grass with a fishing line

It is safer to mow with a trimmer that has a trimmer cord or fishing line than to work with knives. However, the efficiency will be lower. It is always better to choose consumables for certain tasks and combine them.

When working with a gasoline trimmer that has a trimmer line installed, you need to adhere to the following tips:

mow at a height of about 10 cm above the ground;
First mow the upper part of the grass, and then cut the stem at the base. this will help to avoid winding on the working part;
It’s best to drive the machine in the same direction in which the coil rotates;
When mowing the lawn, it is better to work with the ends of the fishing line to reduce the load on the engine;
Every 15 minutes of work you should give your petrol trimmer a rest.

How to mow grass with blades of grass

The blades (disk) are good for hard grass or bushes, but you have to follow some safety rules. Here are the main points to keep in mind when using blades:

The blades are suitable for cutting hard grass, young trees or shrubs.
The more difficult the task, the larger the diameter of the blade disc should be.
Install only discs on the grass trimmer that are the right size for the tool’s capabilities. Otherwise, the grass trimmer may break.
If the tool is on, you may only mow with it, but do not change consumables, lubricate or inspect the gasoline trimmer.
Choose the discs according to the information on it and follow the manufacturer’s instructions.
Do not sharpen the blades yourself, it could ruin the part.

How to mow grass correctly with a line trimmer?

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

Safety precautions during work

Technique of the trimmer with a string and a disc has some differences. The trimmer line cuts the grass at its tip, but if you go too fast, it cuts the entire length. The result is that the stems are not cut, but the grass gets wound around the cord and the motor is overloaded. That’s why it’s important to choose the best line speed. over, mowing tall and tough grass consumes trimmer lines faster than mowing the lawn.

There are a few simple recommendations which, if followed, make mowing more effective and efficient.

Trimmers with a bottom-mounted motor are great for mowing lawns, flowerbeds and edges of lawns. The plane of rotation of the coil of such a device can be placed perpendicular to the ground.
Dense thickets, large weeds, bushes need to be mowed with discs or special attachments.
When clearing large areas, the unit should be tilted to the left, in the direction of the sweep.
To mow the grass around flower beds, shrubs and other objects, you should turn the grass trimmer head with the hood to them. In this way you can mow and not damage the objects themselves.

Remember that the bobbin or disc must not touch the ground or any obstacles other than grass or twigs that you want to cut.

Working safely with brushcutters involves the following safety precautions.

Do not use the trimmer in rain or high humidity.
Keep people and animals at least 15 meters away from the cutting head: grass clippings, small debris and stones may fly out from under the cutting head at high speed and cause injuries.
Grass trimmer operator should wear heavy clothing that completely covers arms and legs.
Wear protective goggles, gloves, headwear, closed shoes, special earphones or earplugs.
The lead to the grass trimmer must be behind the mower.

So, the use of handheld devices for grass mowing allows you to maintain order on a small plot. It is more convenient to use a mower on large areas. In addition, the grass trimmer is relevant when making hay and tidying up the territory: small grass clippings can be used to mulch 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 cord trimmer is safer, but not always optimal. As they say, it is worth choosing a cutting mechanism for the peculiarities of your area of work or use integrated systems, where you can operate both the disc and the cord for the trimmer, if necessary, setting the first, then the second.

As we have already written, the lawnmower with a fishing line can be automatic, semi-automatic and manual. In the first case, the cutting element is “thrown” itself after each new start of the device. This is very convenient, but not economical enough, for example, if your area is irregularly shaped, and contains corners, jagged edges, and during the long transition to each of these areas the mechanism must be novo to turn off and on.

It’s important for the operator to understand that the length of the line tips he sees in front of him when extended is exactly the diameter that the device will mow. You can read about how to thread a line in a spool in one of our articles, but the most important thing to remember is that the length of the line ends should be optimal for proper mowing.

How to mow with a chainsaw correctly? This should be done so that it lasts as long as possible:

keep the reel 10 cm off the ground;
when working with tall grass. mow it at the top, and then already at the stem to protect yourself from it winding up on the device
lead the device in the same direction in which the coil rotates;
Lawn grass, especially near walls and garden décor, it is better to mow with the ends of the line, so as not to overload the engine;
Take a break every 15 minutes.

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

Ideally, tall grass can be mowed with a powerful trimmer with a strong line. But you must admit that the ground where weeds grow is not always smooth, landowners often have bushes and all kinds of garbage, stones, etc. on their plots. To avoid wasting expensive equipment it is better to mow in two stages.

If you are going to make hay and you know the condition of the ground more or less, then you may forecast your work easier. Any grass-cutting machine can handle tall growth. The main thing is to take your time and do it right, as we demonstrate in the practical video.

Do not overload the machine;
If the grass gets tangled, switch the machine off immediately;
Do not mow wet grass, even with a gasoline trimmer.

Cutting different kinds of vegetation

In addition to holding the knife parallel to the ground and cutting thicker brush with the left side of the knife, there are a few tips to consider for each type of vegetation you may encounter:

Grass and weeds

To cut tufts of grass and weeds, make sweeping motions back and forth in long arcs, as if you were using a scythe. Hold the grass trimmer so the blade barely hovers above the ground.

Dense shrubbery

Cutting thick, dense bushes starting at the base of the plant is not the easiest way. Instead, start by bringing the blade up to about waist level, keeping it parallel to the ground. Lower slowly until the blade is just above the ground. Never lift the blade above waist level.

Small trees and seedlings

You can use the grass trimmer with a saw to cut down trees up to 2.5 cm in diameter. For larger diameter trees, use a chainsaw.

Hold the grass trimmer so that the blade is 5-15 cm above the ground. Hold a steady position and press the left side of the brushcutter against the right side of the tree. Cut evenly, without jerking.

Do you have to throttle off when cutting with the brushcutter or throttle up fully??

The owner of a petrol brushcutter needs to know a lot of different nuances that should be taken into account when working with such equipment. often than not, brushcutter owners, especially people who have recently purchased such a device and have never worked with it before, ask one question: should the throttle be dropped when mowing or is it possible to throttle at full throttle?

The brushcutter must be started safely on the ground. Of course, some users know how to start such a tool by holding it in their hands. However, it is worth noting that this method of starting a gasoline tool is complex and dangerous, so you should not use it in practice. Before using such equipment, it is recommended to perform a proper balancing of the belt so that the weight of the tool is not on the hands, but on the shoulders of the user.

During mowing you should make smooth, slow movements of the grass trimmer from one side to the other. The machine should be at the same distance from the ground at all times. During mowing the operator should make small movements, about half a step (to keep to so-called “duck step”).

Is it necessary to cut off gas while mowing grass with a trimmer or is it better to work at one speed (full throttle)?? Some users, especially beginners, who have recently purchased a gasoline grass trimmer, often face the problem of maintaining the revolutions of such a device during the mowing. It is worth noting that it is recommended to change the engine speed while mowing, taking into account the density of the mowed vegetation. To mow young, soft, thin grass, it is not necessary to work the trimmer at high revolutions and turn it on full power.

When working with such a tool, the mower, first of all, must feel and monitor its work. If the mower does not cope with mowing vegetation, then the speed can be increased. However, most experts and experienced users, argue that constantly work with such equipment at full speed can not.

This is due to the fact that if you do not reset the throttle, and work the trimmer at one power (at high revolutions), then the consumption of the fuel used increases significantly. In addition, this mode of operation leads to accelerated wear and tear of parts and components of the device. That’s why it is recommended to reduce the throttle during the return trip when mowing grass. This will allow the internal combustion engine to cool down a little, and the parts will be lubricated at the same time, due to the closure of the throttle.

When you ride with the brushcutter at a single engine speed without dropping the throttle, the fuel consumption increases sharply. over, such way of mowing at constant high RPM can cause overheating of the grass trimmer engine and consequently provoke its breakdown.

It should be noted that during the gas release the grass is evenly mowed and accurately placed in so-called swaths. Put simply, when the machine is moved to one side, the vegetation is mowed, but when it is moved back to its original position, the so-called swath is formed.

Preparing for the first lawnmower start

Before making the first start of the lawnmower it is necessary to make a number of sequential actions:

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

Basic brushcuttering techniques and rules

To get good mowing results and long service life it is important to use and look after your brushcutter properly. Even if this is your first time holding a brushcutter you will soon get the hang of correct mowing techniques. The machine is simply rotated in a semi-circle from right to left, moving evenly forward.

Below we show you the basic techniques and methods that help you to mow even large areas fast and get the best result.

The basic mowing technique is the most common method.

Because the cutting attachment turns counterclockwise, it is more common in working practice to mow from the right to the left.The advantage of this technique is that grass cuttings drop on top of the cut surface.

Large, flat surfaces are the right technique.

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

Basic technique in case of high grass.

If the grass is very high or tougher weeds it is advised to mow in both directions of movement: first you cut the higher part of the mowed grass in one movement to the right, and in the opposite direction (to the left) the lower part. Even in this case the grass cuttings will lie on the left side.

Along the slope. swath after swath.

You will get very good progress by mowing in a straight line particularly on a slope: cut a swath parallel to the slope and then return to the mown area. Then mow the next higher swath. Here the cuttings are always placed on top of the area that has already been mowed.

Skilfully negotiate the obstacles. playfully mow.

To mow around trees or bushes without damaging limbs or trunks, a filament cutter is ideal. If there are many plants in close proximity to one another, mowing around is recommended before mowing. To do this, use your brushcutter‘s guards as a guide. Always drive it up and around the tree or bush. The trunk remains protected, the area around the trunk will be mowed.

Checking and lubricating the gearbox of your brushcutter

Checking the gearbox before starting a petrol grass trimmer should be done on a regular basis. Lack of lubricant or a small amount of it increases friction in the gear reducer gearing, which operates at a fairly high RPM. Overheating and overheating of the gears will result. Gearbox of brushcutter fails. It helps to prevent this type of damage during use and is a result of constant inspection.

If you find, before starting the gasoline grass trimmer, a lack of lubrication in the gearbox or its absence, put “LITOL” in the housing. To do this, you need to unscrew the screw on the bend of the gear housing and fill it with 1-2 ml of LITOL.

When working with a gasoline trimmer for a long time, every 8-10 hours add grease to the boom gearbox.

A few more tips when working with a brushcutter

Mowing. Hold the grass trimmer head directly above the ground at an angle. The work is done by the end of the string. Allow the line to run at its own speed. Do not hold the brushcutter line against the mowed area! Doing so overloads the engine and mowing head. they can break down or melt!

Trimming. The grass trimmer is ideal for cutting grass that’s hard to reach with a regular lawnmower. Keep the string parallel to the ground during cutting. Avoid pressing the trimmer head against the ground, as you can damage the lawn and damage the tool.

Cutting with a knife. If you mow from side to side in a reciprocating motion, the movement from right to left is working and from left to right is reciprocating. The blade should cut the grass with its left edge (between 8 and 12 on a clock face).

How to adjust brushcutter mounts

To begin with, some lawnmowers, especially those of Chinese origin, are simply impossible to balance due to the too small size of the boom and handles, lack of adjustment and support belt. Let us dwell on the last position in more detail.

The brushcutter usually comes with oblique straps (sometimes not at all). However, professionals prefer special backpack straps, the design of which is designed to distribute the load evenly over the body. That’s why it makes sense to buy a backpack belt, especially if you regularly mow large areas.

Before you start working with your brushcutter you should always adjust the belt to make it comfortable to work with:

The hook should be just below. palm width (10 to 15 centimeters). the hips in a strictly horizontal position.
Hang the chain saw on the belt between the engine and the handles.
To balance and secure the device use a cleat or hinge. In the latter case, you can make finer adjustments by moving the loop on the bar.

Ideally, after these adjustments, the chainsaw should hang loosely on the strap without touching the ground or scraping upwards. In this case, the distance from the ground depends on the task at hand. when mowing the lawn is enough 5-10 inches, but when working with high grass should leave 20 to 30 inches.

If you use a backpack belt, you must also adjust the length of the shoulder straps, which must not sink into the body or sag freely during work. If you have trouble adjusting the backpack belt, it’s worth looking at the instruction manual. You should also secure the position of the shaft so it does not accidentally obstruct the engine exhaust system.

To adjust the handles you need to find a position that doesn’t allow your hands to hold the tool in the air, but only gives you direction. Make sure that the boom can move freely so that the handle does not strike your leg when mowing.

Warning. If after adjusting the handles you become out of balance, all the adjusting steps have to be carried out again.

How to hold the brushcutter correctly

After the tool is perfectly balanced and the operator wears protective harness and an off-load belt, you can start the tool, fasten it to the hanging strap and go on mowing, keeping in mind the following recommendations

The cord reel or disk must be held at the same distance from the ground, which depends on the task at hand (see above);
move about the mowing area at a leisurely (duck-like) pace;
The bar should move smoothly and not too fast;
Avoid too great a swing so that the handle does not strike your leg;
It is better to mow in the direction in which the trimmer line or disc rotates;
if a chainsaw cannot cope with the high grass, we make two passes. firstly mow the top, and then the lower part;
it does not make sense to keep the revolutions at the same level (if it is a disc, and not a cord coil), because you can significantly save on fuel when they are reset in the backward progression.

we hope that these simple tips will help users learn to work with a chain saw correctly. After all, with this tool, with the right approach, you can quickly beautify the homestead or garden plot so that after this work “nothing hurts”.
