Protective cover for grass trimmer with their own hands

How to make a half-damaged protective cover on the trimmer. Trimmer with an electric screwdriver with his hands. Where and what is more beautiful?

The question of how to make a trimmer with their own hands, always relevant among the owners of private houses with a small plot of land. Accurate and well maintained lawn near the house, it is not only beautiful, but also safe in terms of the absence of nests on it.

About how to get rid of bed bugs on the property spoke earlier, today we will look at the issue. How to make a trimmer with your own hands with the most pidruzhivnyh for this money.

Today on sale can zuzvrity different variants of trimmers, which operate both from electricity and from gasoline. However, it is not always possible to buy a trimmer for the grass, and for the most part, otherwise it is not so much needed.

The advantages of the self-rolling trimmer for grass or angle grinder are that when you need to mow the lawn next to the house, the grass trimmer is easily assembled. If necessary, the drill or angle grinder from the trimmer for the grass will be removed and used for their intended purpose.

How to make a trimmer with a drill and angle grinder

In order to make a trimmer from the drill a lot of materials and tools are not needed. You will not need to disassemble the core drill to make it a hand trimmer for grass with his hands.

In addition, the drills can be replaced by a battery-powered electric screwdriver, which can be connected to a car battery to increase the work time trimmer for grass.

How to make a trimmer for the grass with your own hands

The main requirements for the self-trimmer first of all are to ensure its safety. The blade of the grass trimmer is very sharp, so the presence of a protective cover on the trimmer is a must.

The same applies to the handle of the grass trimmer, on which will be fixed the drill. Handle must be made of durable materials, you can, of course, with wood, but it is better to use aluminum tube for this purpose.

Besides this, it is not only extremely safe, but also handy to operate the trimmer after it is assembled. So you should definitely adjust the trimmer’s holder for the grass to your height, maybe install on it the additional handle on the side, etc. Д.

First, the grass trimmer arm is prepared, on which the drill should be mounted. To fix the drill you will need long bolts and metal clamps. The core wire must be necessarily fastened to the handle of the grass trimmer. It is not allowed that the lead wobble and constitute a safety hazard if it hits the cutting element of the grass trimmer.

How to make a cutting tool for the grass trimmer: materials

The blade of the self-powered grass trimmer is secured to the trimmer arm with a nut and screw, which is riveted into the cartridge. Necessarily before this it is necessary not to forget and to install on the grass trimmer protective cover to ensure own defect in the time of mowing grass.

Trimmer blade can be made of tool steel or other durable material. You should know that the less is the thickness of the knife other than the trimmer, the better it will cope with a sharp grass. Grass trimmer blade length depends primarily on the blade guard and the width of the mowed grass. Often the length of grass trimmer blade does not exceed 30 cm.

Trimmer with an angle grinder with his hands

The question of how to make a trimmer with an angle grinder with your own hands is solved approximately the same way as described above for making a trimmer for grass from wood. There is only a small difference in fixing the angle grinder to the holder. As a handle for trimmer can be inverted metal pipe, to which at the end of the device is necessary to weld a plate with a lap for fixation of the angle grinder bolt.

Some small changes were made to the blade of the self-made grass trimmer. In the case of the angle grinder, it is not in the form of a long straight grinder. A blade of self-made grass trimmer from angle grinder made of concrete disk with sharp edges cut beforehand, which precisely is intended for grass mowing.

The question of how to make a trimmer from a drill or angle grinder can generally be solved in a self-sustaining way The main thing is not to forget about the technology of safety and carefully study this issue.

Only after that, you can bravely take up the manufacture of trimmers for grass with their own hands.

How to make an electric trimmer with your own hands from the saw or other power tools

The issue of careful and quick grass mowing near the summer house I came across long ago when I had a chance to learn how to use a conventional scythe. Lithuanian.

Immediately thought that would not interfere simple lawn mower bought at that time was not easy. So I decided to experiment with a self-made design.

I finally gained some practical experience in mowing the grass, thanks to which I was able to buy the trimmer, which is well suited to my goals.

On the basis of the acquired knowledge I will make recommendations home builder how to make their own hands electric trimmer of the old device on the basis of the electric propeller in the saw, drills or angle grinder with pictures, diagrams and photos, which permit to repeat a similar design.

Please note that my lawnmower was assembled by hand from the most available materials. The fixtures are designed for reliable operation without any design considerations, but with a basic safety requirements. So do not judge harshly for unrepresentative appearance of the design.

Safety rules

So this section to remind: any self-made construction of a lawnmower can damage Skoda’s health. Particularly relevant tshema for:

Eelektrichna nebespeka trimmer for grass

Electricity does not think about your health. It creates a path of the jet where it is given the best conditions and less electric intensity. They can even be struck by the blast from accidental things: clothes, moving objects, the car, which is standing on the ground. There is nothing marvelous about it. You must be careful about yourself, use protection equipment.

When building the electrical trimmer by your own hands immediately pay attention to the strength and quality of insulation of all live parts inside the motor as well as on the external circuitry. A qualified electrician must do the installation.

When working, the self-made grass trimmer is indispensable:

All three converted devices must be inspected. They must meet the safety requirements in terms of their technical specifications, settings and be correctly installed.

Safety precautions of the mechanical circuit

The commutator motors develop very high speed of rotation. In pilots, they can be from 11000 to 30000 rpm. This is quite enough for a small stone, a piece of dart or a piece of grass, to fly from under the cutting head.

The difference will be in the fact that the direction of the die is chosen by the sniper, and the rocker from the lawnmower. encounter. It is impossible to predict where he will fly to. Therefore, when working you need to:

  • Ensure a stable position of the body, which is a general safety concern when working with all the tools;
  • Protect yourself with clean clothes made of natural soft fabrics or jeans;
  • wear a solid piece of clothing rather than open sandals on your feet;
  • to use the eyepieces or the mask.

Lawn mower with the electric motor from the saw

  • commutator motor;
  • A knot of the yoke on a wooden rod;
  • a self-made cutting knife;
  • support wheel;
  • buttons of the winch;
  • protective covers.

electric motor

As the basis for the design of the lawnmower was taken colector motor in the old 300-watt Buran sawmill of the early times. Its intended use was discontinued after its wear and tear caused the airflow to deteriorate as a result of repeated use. I was afraid to repair the leakage, which is manifested by the pressure and the oscillation, so I bought a new one.

External view of the fully assembled grass trimmer from the side of the engine shown in the photo. Since it is no longer in use, it is covered with rust, and the fillings of grass clippings dried out long ago and stuck to all parts. It is much easier for me to work with the factory design.

The engine did not have to be rebuilt at all. Just with the help of an electric drill, fishing line and a metal scissor I made a few sawing elements and zahisni covers. In the back photo, the lifted mat was removed from a plastic beach which covers the brush head.

In this picture you can not see the running gear, but it can be seen higher.

For greater clarity lifted the casing with a finger and showed the large plan of the engine on the side of the brushes. All factory details have remained in good working order.

The condenser which was repaired at the factory worked on the opposite side.

The rod

Clamping all the details of self-grinding grass trimmer was made on a dried wooden palitsi without any of their treatment. I drilled some holes in it and screwed some details, e.g. handle bracket with a piece of wood.

All of these joints are visible in various pictures.

Self-operating rotary tool for grass

When I took off the fan crank, I noticed that the spot on the rotor shaft had been released, which was ideal for mounting a self-made knife. Even the nut and gaskets did not have to be selected.

Unreliable experience

At first I tried to mount various diameters of drills on the shaft. It started to mow the grass normally, but very quickly it frayed. Її structure is not subject to mechanical stress caused by heavy engine revolutions and grass. That’s why trimmer manufacturers produce different types of hair.

The method of making a lawn mower

protective, cover, grass, trimmer

I made a knife for a self-made trimmer for grass for such a technology:

  • Using a metal plate of mild steel;
  • To cut it into a rectangular shape;
  • drilled a hole in the center to the diameter of the shaft;
  • ground edges to reduce the impact during mowing.

From a vacuum cleaner

the grass trimmer from the engine of a vacuum cleaner is made by the same principle, as from an angle grinder. The motor needs to be fixed to the boom, and either knives or a plastic or metal disc should be attached to the motor shaft, in which to insert a fishing line for the trimmer. The cutting tool is covered from above with a protective hood.

To prevent dust and small particles of grass clippings from getting into the motor removed from a vacuum cleaner, it can also be hidden in a plastic cover made from a sewer pipe , as shown in the following photo.

Since the motor in the vacuum cleaner is high-speed, it needs provide cooling. Therefore, it is recommended to insert a self-made disk with cut and bent blades under the washer, in which the line for the trimmer is inserted, so that it acts as a fan, which creates vacuum. This is required so that air can be sucked in through the hose from above to cool the motor.

To lighten the load on the mower operator’s hands, the machine can be set it on a platform with wheels. In this case already will turn out something similar to a lawnmower.

To secure the lines, it is also possible to use either a pulley with a suitable hole in the housing or a plastic wheel from a shopping cart.

From the drill

The simplest mower is made in minutes from a drill or electric screwdriver. But first you must make a knife from a sharpened metal plate with a hole drilled in the center. A bolt is inserted into this hole and secured with a nut.

As the drill with the given nozzle has no protective cover, such tool is dangerous enough for the user. To be on the safe side, the drill can be placed, like an angle grinder (mentioned above), on a shovel cutter or aluminum tube.

Also, to protect the user of the mower from the blades, you can attach a cover on the drill (mounted on a plastic tube, and put on the body of the machine).

Drill is attached to the boom with clamps.

How to make a blade for a grass trimmer: materials

Self-made trimmer blade for grass is attached to the drill nut and bolt, which is clamped into the chuck. Be sure not to forget to install on your trimmer for grass trimmer protective cover. To ensure your own safety while mowing the grass.

The blade for the grass trimmer can be made of tool steel or other very durable material. Grass trimmer reel How to make a grass trimmer reel It is therefore extremely important to choose. You should know that the smaller the thickness of the blade of grass trimmer, the better it will cope with cutting the grass. Grass trimmer blade length depends primarily on the blade guard and the width of the grass to be mowed. Most often, the length of the grass trimmer blade does not exceed 30 centimeters.

Grass trimmer from the angle grinder with their own hands

The question of how to make a trimmer for grass from the angle grinder with their own hands, is solved in approximately the same way as the above-described manufacture of trimmers for grass from a drill. How to make a grass trimmer blade for grass trimmer boom hole and. If you are interested in the following questions, for example: How to make a fuel mixture for a grass trimmer (lawnmower). There is only a slight difference in the attachment of the angle grinder to the holder. As a handle for the grass trimmer, a metal tube can be chosen, to which a plate with a hole for fixing the angle grinder with a bolt should be welded on the end.

Some changes have also affected the blade of the self-made trimmer for grass. In the case of using an angle grinder, here the knife is not in the form of a long rectangle. Knife self-made trimmer for grass from the angle grinder made from the disk on the concrete, with a pre-cut sharp edges, which are just designed for mowing grass.

The question of how to make a trimmer for grass from a drill or angle grinder is quite solvable and an independent way The main thing is not to forget about safety and carefully study this issue.

Only after that, you can safely get down to making a trimmer for the grass with their own hands.

Proper maintenance. the key to long and reliable operation of the tool. Primitive maintenance operations include timely gear lubrication and cleaning of the grass trimmer filter. What to lubricate the trimmer gearbox for grass, the user must know. Cleaning is done in stages: After removing the hood, the element is removed. Then it is flushed with gasoline and dried.

What useful home-made items can be made out of a chainsaw? The chainsaw is very popular among home makers, as it is a universal drive for unique homemade structures. Light weight and enormous power combined with compact size allow this “woodcutter’s dream” to be hooked up to an ice pick and an ice pick.

A neatly cut lawn is not only beautiful in itself, but also indicates the status of the owner in a certain way. Nowadays it is not very difficult to find a lawn mower, suitable in performance and design. But there is another way. If a mean power electric motor lying around in the economy, then, after spending a few evenings, it can easily be converted into a simple and convenient homemade mower, while saving not that small amount of money that would have to shell out for a brand-name lawnmower. and even have fun doing it.

Layout of the lawnmower

  • Engine.
  • Framework, to which all components of the mower are fastened.
  • knives.
  • Protective cover.
  • Wheels.
  • Control knobs.
  • Control system parts: switch, RCD, power cable with plug.

The frame of the simplest design is a metal sheet of thickness of 2-3 mm with a hole in the middle for the passage of the motor shaft. The plate is strengthened by a frame made of metal corners. The motor is attached to the sheet from above, the bottom. A protective casing, along the sides of the axles for the wheels, and handles for steering.

If the motor is flanged, it can be attached directly to the sheet by drilling holes in the latter to match the holes in the flange. If the engine is of conventional design, to the sheet should be welded or bolted two perpendicular columns of angle, so that they coincide with the legs of the engine.

Homemade lawnmower. Attachment of electric motor to corners.

holes are drilled in the corners for fixing the motor. If the holes are made in the form of slots, it allows shifting the motor relative to the frame while mounting, thus changing the distance from the blades to the ground. This design feature will be useful when selecting the optimum cutting height of the grass. But it is easier to make holes for different heights of the motor.

The central place of the lawnmower is the cutting unit, consisting of a mandrel with two short (or one long) knives attached to it.

The engine

A good choice is an asynchronous motor with 500-600 watt or more and a speed of about 3000 rpm. A big advantage of the asynchronous motor, is its low noise. The higher the speed of the motor, the better and smoother the mowing. Actually, the quality of mowing is determined not by the rotation speed of blades, but by the linear speed of the cutting edge relative to the grass. The greater the diameter of the cutting edge, the higher the speed of the cutter at the same RPM is, the higher the feeder speed of the tool (diameter of the circle the cutting edge turns on). Therefore, if the working width is large (more than 40 cm), the engine speed must be low. But in this case the motor power needs to be higher. to overcome the increasing resistance. Practice shows that the following variant is quite serviceable: Gripper. 50 cm, motor power. 1 kW, RPM. 1500 rpm. But in principle, a 500 watt motor with 1500 rpm will cut the grass, though worse. Only if the motor power is low, the blades have to be resharpened regularly.

To connect a three-phase motor to a single-phase system you must use a circuit with running and starting capacitors. There is plenty of information on the Internet about connecting three-phase motors to single-phase networks. It is not difficult to find and formulas for calculating the necessary capacitance of capacitors. In practice they take about 200 uF for a motor of about 2 kW. For 500-600 W is enough 60-80 mcf.

Making a casing for the engine, you need to provide holes for engine cooling.

Make a lawn mower with their own hands can also be made using an ordinary electric drill with a speed of up to 3000 rpm. It is not so difficult to invent the fastening of the drill to the frame. However, you should understand that in terms of reliability and duration of continuous operation, the drill is not comparable with an induction motor, so if you have to mow a relatively large area, you should give preference to the latter.

The drill is more suitable for making a homemade trimmer for grass.

In the case of a drill, it is very easy to make the blade mount. The knife with the hole in the center is clamped by the nut on the bolt, and the bolt is clamped in the chuck of the drill.

How to make an electric trimmer for grass with their own hands from a vacuum cleaner or other power tool

I faced the issue of accurate and quick grass mowing near the fence of the country house long ago, when I had to learn how to use an ordinary scythe. Lithuanian.

I thought right away that it wouldn’t hurt to buy a simple lawn mower, which at that time was not easy to buy. So I decided to experiment with a homemade construction.

As a result, I gained practical experience in mowing grass, thanks to which I managed to buy a grass trimmer, which suits my purpose.

Based on the knowledge gained, I give tips for home maker on how to make your own hands electric trimmer for grass out of used equipment based on the electric motor from a vacuum cleaner, a drill or an angle grinder with pictures, diagrams and photos, allowing to repeat a similar design.

Note that my lawn mower was assembled by hastily from the most available materials. Its attachment was made for reliable work without observing any design conditions, but with the requirements of elementary safety. So don’t judge too harshly on the unpresentable look of the construction.

Safety rules

I will start with this section to remind you: any homemade lawn mower design can cause damage to your health. This requirement is especially relevant for:

Grass trimmer electrical hazards

Electric power does not think about your health. It creates an electrical path where it is best suited and has less electrical resistance. You can even get an electric shock from random things: clothing, surrounding objects, a parked car. There is nothing strange about this. It is necessary to take care of yourself, use protection means.

When building an electric grass trimmer with your own hands, immediately pay attention to the strength and quality of insulation of all current-carrying parts both inside the motor and on the external circuit. It must be installed by a qualified person.

During the work of the homemade trimmer for grass is necessary:

All three of these devices should be tested. They must meet safety requirements in terms of technical specifications, settings, be properly adjusted.

The dangers of mechanical circuitry

Collector motors develop very high rotation speeds. Vacuum cleaners have a speed range of 11,000 to 30,000 rpm. This is enough to cause a small pebble, piece of wire, or splinter to fly out from under the cutting head like a bullet from a rifle.

The difference will be that the direction of the bullet is chosen by the sniper, and the pebble from the lawnmower. case. It is impossible to predict where it will fly. Therefore, it is necessary when working:

  • Ensure a stable body position, which is a general safety requirement when working with all tools;
  • protect yourself with thick clothing made of natural cotton fabrics or jeans;
  • wear sturdy shoes on your feet, not open sandals;
  • Use goggles or a protective mask.

Lawn mower from a vacuum cleaner motor

  • collector motor;
  • the knot of its fastening on the wooden bar;
  • homemade cutting blade;
  • support wheel;
  • The switch button;
  • protective covers.

The electric motor

The lawnmower is based on a collector motor from an old Soviet-era 300-watt Buran vacuum cleaner. It was abandoned after various gaskets began to wear out as a result of prolonged use, the air flow was disturbed. I got tired of having to fix the fissures that were appearing, affecting the head and suction, so I bought a replacement.

The appearance of the assembled grass trimmer from the engine side is shown in the photo. Since it is no longer in use, it is covered with rust, and the remains of grass clippings have long dried up and remain stuck to all parts. I am much more comfortable to work with the factory design.

No need to rebuild the motor at all. Just made some fasteners and covers with an electric drill, a vice and a hacksaw. Here’s another photo of a cover cut out of a plastic bottle for the brush unit.

In this picture you can hardly see the working blade, but it can be seen above.

For better visibility lifted the protective cap with finger and showed close-up of the motor from the side of the brushes. Here all the factory parts are still in working order.

On the opposite side works the factory-mounted condenser.

The boom

All parts of the homemade grass trimmer are fastened on a piece of dried wood stick without any treatment. I drilled some fixing holes in it, and screwed some parts like the handle bracket with a piece of wire.

All of these connections can be seen in the different pictures.

Homemade blade for grass

It is noteworthy that when I removed the fan impeller, I saw: the free space on the rotor shaft is ideal for attaching the homemade knife. Even the nut and gasket didn’t have to be adjusted.

Bad experience

At first I tried attaching wire of different diameters to the shaft. It started to mow the grass normally, but very quickly broke off. Its structure could not withstand the mechanical loads of breaking and bending developed by high engine speeds and oncoming grass. That’s why trimmer manufacturers produce different kinds of fishing line.

The way of making a lawnmower

Made a knife for homemade grass trimmer by the following technology:

How to make a trimmer for grass with their own hands from the angle grinder, vacuum cleaner, drill, chain saw

All owners of homestead plots face the problem of mowing the grass, which literally grows before their eyes, and during the season you need to improve your site several times. The usual hand-held scythe has long been replaced by benzotrimmer and electric trimmers. But the price for them is not reduced and is quite tangible for many owners of cottages and private houses. Folk craftsmen have still found a way out of this situation and learned to do with their own hands trimmers for grass literally from improvised means, using gasoline and electric tools, not intended for these purposes.

From the angle grinder

Most often, self-made electric trimmer for grass is based on the usual angle grinder, which is available to every home master. This tool is almost ideal for converting into a trimmer for grass. It has more power than store machines and a higher number of revolutions per minute. In addition, regular nut, used in the angle grinder to secure the discs already has holes through which it is easy to insert a line for the trimmer (cord).

So, there are many options from what to make a rod (holder). The simplest is a longer than for a shovel, a wooden holder. To the end of it at the desired angle is attached an angle grinder with the usual adhesive tape. The line for the trimmer is inserted into the 2 holes of the nut, and then it is screwed. In just a few minutes you can make a grass trimmer, with which you can easily mow the lawn.

For safe operation of the homemade machine, you can improve it, making a protective cover (how to do this will be discussed later).

For advanced craftsmen who have a welding machine, you can advise a more advanced design for fixing the angle grinder and protective cover. It is made of an aluminum tube (serves as a holder) and a metal square profile. If you look at the picture below, you can see how the pipe is made.

Angle grinder is fixed on the holder with bolts, inserted into the holes that are designed to attach the handle to the machine.

The following photo shows how this construction looks like from below.

By the way, the holes for mounting the handle can be screwed and the holder itself (rod), when you want to make a simple trimmer for the grass, which is easily collected and just as easily dismantled, if you need to use an angle grinder on its direct purpose.

To make it more convenient to hold the grass trimmer in hands during work, and it did not rotate around the axis of the boom, you can attach a side handle, made from a bent pipe.

From a vacuum cleaner

The grass trimmer from the motor from the vacuum cleaner is made on the same principle as that of the angle grinder. The motor needs to be fixed to the boom, and either knives or a plastic or metal disc should be attached to the motor shaft, in which to insert a fishing line for the trimmer. From above, the cutting tool is closed with a protective cover.

To prevent dust and small particles of grass clippings from getting into the motor removed from the vacuum cleaner, it can also be hidden in a plastic cover made from a sewer pipe, as shown in the following photo.

Since the motor in a vacuum cleaner is high-speed, it needs to be cooled. Therefore, under the washer, in which the line for the trimmer is inserted, it is recommended to insert a homemade disc with cut and curved blades, so that it acts as a fan that creates a vacuum. It is required so that air is sucked in through the hose from above and cools the motor.

protective, cover, grass, trimmer

To lighten the load on the mower operator’s arms, the machine can be mounted on a platform with wheels. In this case, you already have something similar to a lawnmower.

To fix the line you can also use either a pulley with a suitable hole to fit it, or a plastic wheel from a cart.

From a drill

The simplest mower is made in minutes from a drill or electric screwdriver. But first you have to make the blade from a sharpened metal plate with a hole in the center. A bolt is inserted into this hole and secured with a nut.

Since the drill with this attachment does not have a protective cover, then such a tool is quite dangerous for the user. To protect yourself, you can place the drill, as well as an angle grinder (this was mentioned above), on a shovel bail or on an aluminum pipe.

Also, to protect the user of the mower from the blades, the drill can be fitted with a guard (attached to a plastic tube, and put on the body of the machine).

The drill is attached to the boom with clamps.

From a chainsaw

Many different attachments have already been invented for the chainsaw, expanding the capabilities of this unit, for example, a cultivator, a drill, a boat motor, as well as the grass cutter attachment. How it looks, you can see in this video. In case you want to make a trimmer for grass from a chainsaw, the maximum that you can do is a lawnmower on wheels, as the engine of the machine is heavy enough, and to apply the above described options for making trimmers (with the lower drive) to it will not work.

Running-in.

Work off at least one tank of fuel (without load)!) with a frequent change in rpm (idle speed. highest rpm). Next 5 hours of light-duty operation (50% load). After the running-in period, it is necessary to check the engine rpm (with the electric tachometer in the service center) and, if necessary, have them adjusted by a specialist.

Motor. The air filter must always be clean (no dirt or filings) and the foam filter needs to be wetted with oil. The fuel filter should be inspected once a week (change as required). Checking nut and bolt tightness before work. Cleaning of soot from a silencer (or its grid) and plugs. as necessary. Replace the reel with the cap 14 on the removed reel 17 and close the protective cap. Angular gearbox. Once a day, clean off dirt (a similar “coat” does not allow for proper cooling of the gearbox) and put grease on the gear pair.

Assembling the Huter grass trimmer protective cover

Huter Grass Trimmer Protective Cover.

How to make a deflector cover for your petrol trimmer.

line for trimmer and trimmer heads. Use only mowing line designed for the trimmer. do not use wire or metal cords! Only install trimmer fishing line of the diameter recommended by the manufacturer. Wind it tightly on the bobbin, but do not over wind it. Clean the mowing head of dirt and lubricate as needed. Remove the protective guard with the fishing line must be properly installed on the shaft. They are originally installed in the trimmer how to properly put on the guard for. A warped or worn cutting head can damage the gearbox and/or shaft of a brushcutter.

Cutting blades. The cutting parts should be well and correctly sharpened using appropriate templates and files and observing the cutting angles depending on the disc brand. The double-sided blades should be turned 180° at regular intervals to allow for even wear and tear. A blunt blade or a blade that is poorly or improperly sharpened cuts poorly and thus overloads the motor, resulting in a rapid reduction in motor life. Protective covers. The engine on an electric trimmer is not equipped with a safety guard. Never operate your brushcutter without the deflector, it is dangerous to your life and may overload the brushcutter engine. Use only a blade guard for each type of cutting attachment.

Shearing. Hold the grass trimmer head directly over the ground at an angle. The end of the stringline performs the work. Allow the string to run at its own speed. How to wind a line on a thicker cord to prevent the cord from snagging the blade guard. Do not press the stringline against the mowed area! This will overload the engine and mowing head and they may break down or melt!

Cutting with a knife. You mow with a reciprocating motion from side to side, 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 (on the clock face. between 8 and 12). Following the recommendations listed above will prolong the service life of gasoline-powered machines many times over.

Wheels

There is no unequivocal opinion about what number of wheels is optimal. 2, 3 or 4, among the masters who operate homemade lawnmowers. 3 or 4 wheels are good because they set the exact distance from the blades to the ground. Two wheels make the lawnmower more maneuverable and let you cut the grass in all the hidden corners. It is also easier to find two identical wheels than three or four. However, you can make the wheels yourself, for example from plywood and bearings, so the last argument is not so convincing. The choice is ultimately up to the do-it-yourselfer.

If a two-wheeled mower is chosen, there must be protection from touching the ground with a rotating blade.

If a three-wheeled mower is chosen, the two wheels should be on the handle side, so you can lift the front of the mower to turn around by pushing on the handle.

The larger the diameter of the wheels, the better. A lawn mower with small wheels is more difficult to roll on the grass.

At the end of the article there is a video demonstrating the work of the second mower.

Without the bag, the grass will be laid in the side set by the cutout. Without the hole in the hood, the grass will be shredded, it will be mulching. But all this requires a powerful enough engine, and to avoid getting grass clippings in the engine, the space between the engine and the blades must be covered with a disc.

Mower can be operated more safely if one of the handles is equipped with a lever that disconnects the voltage to the engine when released.

Safety Precautions

Carefully insulate all electrical wiring connections. both on the motor itself and on the control parts. The insulation on the power cable must not be broken. To power the electric motor, it is necessary to have a cable with double insulation and having at least 3 wires. The body of the mower must be securely grounded, for which one of the wires of the cable is used. How to make a grass trimmer with your own hands from an angle grinder, vacuum cleaner, drill, chainsaw. Self-made protection cover, blade for grass trimmer, backpack strap.
