The trimmer has a carefully thought out reliable design. But like any invention, the trimmer tends to break down and fail. A particularly common problem with this device is damage to the plastic fishing line spool. During operation, pebbles bounce off the trimmer, which can hit the reel and break it. The coil can also burst for other reasons. The solution to this problem is quite simple - purchase and install a new coil. But since manufacturers make parts only from plastic, they constantly break. And if you’re tired of constantly buying parts for your lawn mower, you can make an indestructible reel with your own hands. This is done easily and simply.
How to make homemade trimmer protection with your own hands
In the summer, to keep your summer cottage looking neat, you have to mow the grass regularly.
A trimmer, a light hand-held lawn mower in the form of a cane, helps you cope with this quickly with a regular scythe. A kind of electric scythe, but instead of a blade it has a fishing line.
A well-known disadvantage of trimmers is that you cannot work with them without special protection (mask and glasses): the grass scatters at high speed in different directions, getting into your face and eyes.
The reason for this is the small shield above the rotating line.
To solve this problem, I trimmed the “original” plastic shield, leaving only the third part attached to the rod.
Then I made a new one from an aluminum sheet 0.2 mm thick and 250x250 mm in size, and attached it with two screws from above to the remaining part of the former shield.
Instead of aluminum, you can use a plate made of rubber or linoleum, but then the shields made of these materials will have to be secured with steel wire so that the edges do not accidentally get caught under the rotating fishing line.
Upgrading the trimmer guard
During the operation of any electric trimmer, one major drawback appears: the resulting grass juice and haylage scatter far to the sides and upwards, covering the mower from head to toe with greenery. You have to use special clothing and a mask to protect your face and eyes, but dust gets into your boots and settles on your headgear. After just an hour of work, the mower turns out to be “all covered with greenery, absolutely all”! You have to spend a lot of time on subsequent “sanitation”.
The reason is that trimmers have an excessively small guard over the rotating line. In mine, for example, the shield occupies only a sector, which on the watch dial corresponds to the numbers from 4 to 8, which is clearly not enough.
To eliminate this drawback, I cut off the plastic shield in my trimmer and left only the third (central) part attached to the rod. Then I made an enlarged shield from an aluminum sheet 0.2 mm thick and 250x250 mm in size, which I attached with two screws from above to the remaining part of the former shield (see figure).
As a result, the resulting new shield began to cover the entire semicircle of rotation of the line facing the mower, protecting him from flying greenery. The effect of this modernization was remarkable! Now even boots don’t get dirty above half the tops.
If there is no aluminum sheet, you can use a rubber or linoleum plate. To prevent the edges of such material from drooping, they will have to be reinforced on top along the perimeter with steel wire. In this case, the peripheral parts of the material must be held in a raised state by the wire. The shield material must be attached to the wire precisely in these places, inaccessible to the rotating fishing line.

Types of semi-automatic heads
A semi-automatic mowing head usually consists of a housing, inside of which there are several springs and a spool. Spools, according to their design, are divided into:
- single-section – in devices of this type, the cutting line used is wound evenly;
- two-section – in these spools, each end of the cord must be wound separately, onto the part intended for this. Two-section spools differ from single-section spools in durability and ease of operation. In addition, the fishing line inside them never bends or gets tangled.
Many owners of household trimmers convert single-section spools to two-section ones. To do this, you will need to find a durable metal plate and apply a contour with the diameter of the spool on it. After this, the plate is cut along the contour so that the thickness is near the place where the cord is wound. As a result, the resulting circle should move freely around its axis. Next, you will need to make a cut on the resulting ring and insert the spool inside the ring. Both parts must be connected to each other using tape or quick-drying glue. As a result, the manufacturer will have a spool in which the line can be wound into two sections.
What can you use to make protection for a trimmer? How to install a protective cover on a trimmer
All owners of personal plots are faced with the problem of mowing grass, which grows literally before our eyes, and during the season it is necessary to improve their plot several times. The usual hand scythe has long been replaced by gas trimmers and electric trimmers. But the price for them does not decrease and is quite significant for many owners of dachas and private houses. Craftsmen nevertheless found a way out of this situation and learned to make trimmers with their own hands literally from improvised means, using gas and electric tools not intended for these purposes.
Most often, a homemade electric trimmer is made on the basis of an ordinary grinder, which is available to every home craftsman. This tool is almost ideal for converting into a trimmer. It has more power and a higher number of revolutions per minute than store-bought machines. In addition, the standard nut used in the grinder to secure the discs already has holes through which it is easy to insert a fishing line (cord).
To ensure safe operation of a homemade device, you can improve it by making a protective casing (how to do this will be discussed later).
For advanced craftsmen who have a welding machine, we can recommend a more advanced design for securing the grinder and protective casing. It is made from aluminum tube
(serves as a holder) and a metal square profile. Looking at the figure below, you can understand the principle of making the holder.
The grinder is secured to the holder with bolts inserted into the holes that are intended for attaching the handle to the device.
The following photo shows what this design looks like from below.
By the way, you can also screw the holder (bar) to the holes for attaching the handle when you want to make a simple trimmer that is easy to assemble and just as easy to disassemble if you need to use the grinder for its intended purpose.
Types of nozzles
Suitable for petrol trimmer (works without the use of electrical energy).
Drill attachment- The “Lopper” attachment works on a similar principle to a hacksaw.
- The “Running Wheels” attachment makes working with the brush easier and easier.
- Garden shears attachment, which is used to trim hedges and bushes.
- the “Cultivator” attachment to loosen beds and flower beds.
- The “Aerator” attachment will help destroy the crust that has formed on the surface of the lawn at your summer cottage.
- The “Gearbox” attachment is suitable for many cases, for example, it can be used as a motor for a bicycle.
- The “Height Cutter” attachment is an excellent option for cutting branches at a height of up to 450 cm from ground level.
- The Brush and Roller attachment is an excellent tool for sweeping paths and lawns.
- The Water Pump attachment will help you pump water from a lake or well.
- The support wheel attachment is ideal for making the trimmer easier to work with other attachments.
- The “Snow Remover” attachment will become an assistant in the winter to clear paths and areas of snow.
- “Motor for a boat” attachment – words are unnecessary here; those who like to fish in the middle of a lake in a cozy boat will appreciate the attachment.
- The blower attachment will blow away fallen leaves from your garden paths.
- The Edge Trimmer attachment is suitable for trimming and making the edges of lawns and flower beds more beautiful.
And all this in addition to the fact that there are trimmer heads for caring for a personal plot, beds, as well as various plastic and metal knives for mowing weeds, natural and seeded grasses, as well as a disc for cutting and cutting young bushes and trees and branches.
From a vacuum cleaner
A trimmer from a vacuum cleaner engine is made according to the same principle as from an angle grinder. The motor must be mounted on a rod, and either knives or a plastic or metal disk must be attached to the motor shaft, into which the fishing line must be inserted. The top of the cutting tool is covered with a protective casing.
To secure the fishing line, you can also use either a pulley with a suitable mounting hole or a plastic wheel from a cart.
What it is?
Cultivator-type attachments for a gasoline trimmer are attachments for cultivating land. In essence, this is a loosening unit, through which you can simplify the cultivation of a small plot of land.
Depending on the type of nozzle, it may vary slightly, however, it is not suitable for several types of work. It cannot be used to plow or huddle the land. She just loosens the soil.
From a drill
Since a drill with this attachment does not have a protective casing, such a tool is quite dangerous for the user. To protect yourself, you can place the drill, like a grinder (discussed above), on the handle of a shovel or on an aluminum pipe.
Also, to protect the user of the mower from knives, a casing can be attached to the drill (attached to a plastic pipe and placed on the body of the device).
The drill is attached to the rod using clamps.

Materials:
- metal perforated plate (100 mm x 240 mm)
- 2 hacksaw blades for metal
- 4 screws and 4 nuts M5
- 4 washers and 4 enlarged washers
From a safety 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 trimmer shaft. That is why a ready-made perforated plate is selected.
Homemade protective casing
If you are making a homemade mower, then you will definitely need a protective cover. It will protect your eyes, body and legs from injury from small pebbles and knife fragments if they break.
In this way, you can make and install a protective cover on a trimmer purchased in a store if the shield has cracked for some reason. The shields in factory devices are made of plastic and often break if you unsuccessfully hit the trimmer head on the ground to lengthen the fishing line.
Fuel mixture
Oil
– high-quality two-stroke oil for high-speed equipment (10-15 thousand rpm, about 200 rpm).
Do not use motorcycle oils (low engine speeds) or for aquatic equipment (other cooling systems) - their use does not provide the necessary lubrication of the piston group and parts of the entire engine! Gasoline
- any pure high-octane gasoline (with a number of 92 or higher, with a density in the range of 750-770 kg/m3).
The proportion of the fuel mixture
is 1:50 (2%) or 20 ml/cm3 of oil per 1 liter of gasoline. For example, pour half a measure of gasoline into a transparent plastic bottle (1 l), then add oil with a honey syringe (20 ml/cm3) and mix, add gasoline and mix thoroughly. If the quality of gasoline is unclear or the working conditions are difficult, then the amount of oil should be increased to 22-25 ml/cm3. Shake the mixture before each filling.

Trimmer belt
For more comfortable work with the trimmer, if you intend to process a large area covered with grass, it is advisable to use a special belt. This device relieves fatigue from the hands and back of the mower operator and greatly facilitates the process when compared with the same work, but without a belt.
The shoulder strap is usually used with lightweight trimmers weighing 3-4 kg. For heavier units it is more convenient to use a backpack belt.
A trimmer belt can be easily ordered online or purchased at a specialized store that sells these devices and their accessories.
The price of backpack belts starts from 250 rubles and above.
If you want to make it yourself, then any housewife, looking at this device, can easily sew it from improvised materials (old belts and belts). You may have to buy buckles and carabiners. But we still recommend buying a ready-made backpack suspension and not wasting time and money on making a device of worse quality than the ready-made one.
I immediately thought that it wouldn’t hurt to buy a simple lawn mower, which was not easy to buy at that time. Therefore, I decided to experiment with a homemade design.
As a result, I gained practical experience in mowing grass, thanks to which I was able to buy a trimmer that is well suited for my purposes.
Based on the knowledge gained, I give advice to the home craftsman on how to make an electric trimmer with his own hands from used equipment based on an electric motor from a vacuum cleaner, drill or grinder with pictures, diagrams and photographs that allow him to repeat a similar design.
Please note that my lawn mower was assembled in haste using the most readily available materials. Its fastening was made for reliable operation without complying with any design conditions, but ensuring basic safety requirements. So do not judge strictly for the unpresentable appearance of the structure.
Safety regulations
I’ll start with this section to remind you: any homemade lawn mower design can cause harm to health. This requirement is especially relevant for:
Let's look briefly at these two factors.
Electrical hazard of trimmer
Electricity doesn't care about your health. It creates a current path where the best conditions and lower electrical resistance are provided for it. : clothes, surrounding objects, a parked car. There is nothing strange about this. You need to take care of yourself and use protective equipment.
When creating an electric trimmer with your own hands, immediately pay attention to the strength and quality of the insulation of all current-carrying parts, both inside the engine and on the external circuit. Its installation must be carried out by a qualified worker.
When working with a homemade trimmer you need to:
All three devices listed should be checked. They must meet safety requirements for technical characteristics, settings, and be properly adjusted.
Mechanical circuit hazards
Commutator motors develop very high rotation speeds. For vacuum cleaners, they can range from 11,000 to 30,000 rpm. This is quite enough for a small pebble, piece of wire or wood chips to fly out from under the cutting head, like a bullet from a rifle.
Lawn mower made from an electric motor from a vacuum cleaner
My design consists of:
Electric motor
The design of the lawnmower is based on a collector motor from an old Soviet-era 300-watt Buran vacuum cleaner. Its intended use had to be abandoned after, as a result of long-term use, various gaskets began to wear out and air movement was disrupted. I was tired of eliminating emerging fistulas that affected pressure and suction, so I bought a replacement.
The appearance of the assembled trimmer from the engine side is shown in the photograph. Since it is no longer in use, it is covered with rust, and the remains of the mown grass have long since dried out and remained stuck to all the parts. I find it much more convenient to work with a factory design.
For greater clarity, I lifted the protective cover with my finger and showed a close-up of the engine from the brush side. Here, all factory parts remain in working order.
On the opposite side, a factory-mounted capacitor works.
Barbell
All parts of the homemade trimmer are attached to a dried wooden stick without any processing. I drilled mounting holes in it, and screwed some parts, for example, the handle bracket, with a piece of wire.
All these connections are visible in different pictures.
It is noteworthy that when I removed the fan impeller, I saw that the free space on the rotor shaft was ideal for attaching a homemade knife. I didn't even have to select the nut and gaskets.
Bad experience
At first I tried attaching wires of different diameters to the shaft. She started to mow the grass normally, but stopped very quickly. Its structure cannot withstand the mechanical tensile and bending loads developed by high engine speeds and oncoming grass. Therefore, trimmer manufacturers produce different types of fishing line.
Method of making a lawn mower
Support wheel
The main disadvantage of this lawn mower design, like all trimmers with a bottom-mounted electric motor, is the need to exert great physical effort to keep the blade in the desired plane when mowing. At the same time, the worker’s muscles tense, and he himself quickly gets tired. Need emphasis on the ground.
Design and mounting options
The design of such a device is usually equipped with one or two pairs of cutting parts. Instead of a gearbox, they are attached to the trimmer at the bottom of the rod or near the motor of the device. Weeding with a brush cutter is done by burning liquid fuel. In order to enhance the strength and reliability of the structure, it has a straight reinforced rod, the diameter of which is at least 25 mm. The bar is designed for optimal working load.

Based on the type of device, it often provides for adjusting the grip width of the cutting elements. As a rule, its indicators vary between 13-25 cm. As for disk cultivator attachments for a gas trimmer, their design can be equipped not only with a pair, but also with several disks with blades attached to them, bent at a certain angle. As a rule, these hinges also have a protective flap that prevents soil from entering during operation of the device.
The design of gear attachments can also have more than two cutting elements. Curved knives can be arranged in a row. At the same time, an increase in the number of knives increases the weight of the cultivator attachment. On average it weighs about 5 kg.
The transmission of torque from the gas trimmer engine to the attachment is carried out via a shaft arranged in the rod. Such a unit is not interchangeable; moreover, it differs in the number of splines available at the end of the rod. There are 7 or 9 of them. This feature is taken into account when selecting an attachment for an existing gas trimmer. A cultivator attachment for a brush cutter with an input shaft of 9 splines and a 26 mm rod is attached instead of the lower gearbox.
The spline method of connecting disks allows freedom of movement of cutting parts. This is convenient specifically for soil cultivation, since it allows loosening the soil with a wide grip in one pass. In this case, there is no need for a large amplitude of movement of the rod.
Trimmer from a drill or grinder
The principle of creating a homemade design based on this tool is exactly the same as in my case.
The principle of fastening the knife
For a drill, you can screw two nuts onto a regular stud, tightening them with keys, and use the plane of the created stop to install the knife.
The knife hole must be drilled in the center, and the assembled attachment must be well balanced. Otherwise, lateral runout will occur, for which the drill bearings are not designed.
Trimmer line attachment
You can make a reel for attaching fishing line with your own hands, but I don’t see much point in this matter. It’s easier to buy it in a store or use it from a broken trimmer.
The fact is that during operation, when the fishing line is shortened, its cutting length can be restored by simply hitting the rotating head on the ground. This function works by maintaining the exact dimensions of the nozzle after complex mechanical adjustments. And disposable fastening of the fishing line requires frequent switching off of the trimmer to replace it.
Take care of your safety first. For this:
A homemade lawn mower helps you experience all the advantages and disadvantages of electric grass mowing, the operating features of such devices, and the need to balance the center of mass. After gaining a little experience in using it, it is easier to choose a factory model that is professionally prepared for long-term use.
In the summer, in order for the dacha plot to look neat, you have to mow the grass often. A trimmer, a lightweight hand-held lawn mower in the shape of a cane, helps to cope with this speed of an ordinary scythe.
A sort of electric scythe, but instead of a blade it has a fishing line.
The reason for this is the small shield above the rotating line.
To solve this problem, I trimmed the “original” plastic shield, leaving only the third part attached to the rod.
Then I made a new one from a duralumin sheet 0.2.4 mm wide and 250x250 mm in size, and attached it with 2 screws from above to the remaining part of the former shield.
Instead of aluminum, they use a plate made of rubber or linoleum, but then the shields made of these materials will have to be secured with metal wire so that the edges do not accidentally get under the spinning fishing line.
While using any electronic trimmer
One big drawback appears: the resulting grass juice and haylage scatter far to the sides and up, covering the mower with greenery from head to toe. You have to use special clothing and a mask to protect your face and eyes; unfortunately, the dust gets into your boots and settles on your headdress. After just an hour of work, the mower turns out to be “all covered with greenery, completely covered”! We have to waste extra time on the next “sanitation”.
Increasing protection on your trimmer at home. Additional protection for the trimmer / Protection trimmer
The reason for this cut is that trimmers have an extremely small shield over the rotating line. In mine, for example, the shield occupies only the sector that on the watch dial corresponds to the numbers from 4 to 8, which is obviously not enough.
To eliminate this defect, I cut off the plastic shield in my own trimmer, leaving only the third (central) part attached to the rod. Then I made an enlarged shield from a duralumin sheet with a width of 0.3.2 mm and a size of 250x250 mm, which I attached with 2 screws from above to the remaining part of the former shield (see figure).
In the process, the resulting new shield began to cover the entire semicircle of rotation of the fishing line facing the mower, protecting him from flying greenery. The effect of such modernization was excellent! Nowadays even boots don’t get dirty above half the tops.
If there is no duralumin sheet, use a rubber plate, or linoleum. To prevent the edges of such material from drooping, they will have to be reinforced on top along the perimeter with metal wire. At the same time, the peripheral parts of the material must be held in a raised state by the wire. The shield material is attached to the wire specifically in these places that are inaccessible to a rotating fishing line.

In order to protect equipment from early wear and tear, manufacturers have provided the possibility of installing special knives on trimmers. The design and shape of the existing cutting parts allows you to easily handle not only coarsened and overgrown grass, but also successfully fight with young bushes.
How to properly place a knife on a trimmer
The algorithm for installing the knife on the trimmer is as follows:
General structure of the lawn mower
If the motor is flanged, it can be attached directly to the sheet by drilling holes in the latter that coincide with the holes in the flange. If the engine is of a conventional design, it is necessary to weld or screw two perpendicular corner posts to the sheet so that they coincide with the engine feet.
Homemade lawn mower. Fastening the electric motor to the corners.
Holes are drilled in the corners for mounting the engine. If the holes are made in the form of grooves, this will allow the engine to be shifted relative to the frame when mounting, thus changing the distance from the knives to the ground. This design feature will be useful when selecting the optimal grass cutting height. But it’s easier to make holes for different engine height positions.
The central place of the lawn mower is the cutting unit, consisting of a mandrel with two short (or one long) knives attached to it.
Engine
To connect a three-phase motor to a single-phase network, it is necessary to use a circuit with working and starting capacitors. There is plenty of information on connecting three-phase motors to a single-phase network on the Internet. It is not difficult to find formulas for calculating the required capacitance of capacitors. In practice, they take approximately 200 uF for a motor with a power of about 2 kW. For a power of 500-600 W, 60-80 uF is sufficient.
When making a casing for the engine, you need to provide holes for cooling the engine.
You can make a lawn mower with your own hands using a conventional electric drill with a speed of up to 3000 rpm. Coming up with a way to attach a drill to a frame is not that difficult. However, you need to understand that in terms of reliability and duration of continuous operation, the drill cannot be compared with an asynchronous motor, so if you have to mow a relatively large area, preference should be given to the latter.
A drill is more suitable for making a homemade trimmer.
Mandrel
The mandrel must be securely fastened to the motor shaft. This is usually done using bolts screwed into the flange perpendicular to the shaft axis.
You can use a stone holder for a sharpener as a mandrel.
To prevent grass from wrapping around the shaft, it can be covered with a tin can.
If a suitable pulley or other suitable parts are not found, you will have to order the manufacture of a mandrel from a turner or make it yourself from a pipe of a suitable diameter and a strip or circle welded to it. There are three problems here: finding a pipe of suitable diameter, ensuring the perpendicularity of the welded strip or circle with respect to the pipe, and centering the mandrel after its manufacture. With some effort, all these problems can be solved.
If drilling holes is problematic, then you can place the blade on a metal surface with a hole slightly larger in diameter than the hole in the blade should be and hit it with a punch. The protrusion formed after the impact is removed with a file (if the metal is soft enough) or with a sharpener. If the hole does not meet the required diameter, the process is repeated.
In essence, there are many options for making functional knives, as well as materials for making them. The main thing is to sharpen them well, center them (so that there is no vibration) and securely fasten them. When attaching knives to the mandrel, you need to use lock washers and locknuts. Without this, the mounting bolts will unscrew due to vibration.
Wheels
If a two-wheeled lawn mower is selected, there must be protection against the rotating blade touching the ground.
If you choose a three-wheeled lawn mower, then two wheels should be on the handle side so that you can lift the front of the mower for a turn by pressing on the handle.
The larger the wheel diameter, the better. A lawn mower with small wheels is more difficult to push through grass.
If the edge opposite the cutting edge of the knives is bent upward (or blades are riveted to them), they will work like a fan, lifting and rotating the cut grass with a stream of air. At the same time, if you make a cut in the casing (in the quadrant where the knives run) and pull a mesh bag or box over it, then the cut grass will be collected in it.
At the end of the article there is a video demonstrating the operation of the second lawn mower.
Without a bag, the grass will be laid in the direction specified by the cutout. Without a hole in the casing, the grass will be crushed, this will be mulching. But for all this you need a fairly powerful engine, and in order to avoid cutting grass from stuffing into the engine, the space between the engine and the knives must be covered with a disk.
Working with the mower will be safer if one of the handles is equipped with a lever that, when released, turns off the power supply to the engine.
Advantages and disadvantages
The cultivator attachment for a gas trimmer, regardless of its type, increases the weight of the assembled unit to 5-6 kg. This is a product that is quite in demand among buyers and is easy to maintain. This device is characterized by a more reasonable cost compared to equipment for a motor cultivator. The cultivator attachment for a gasoline trimmer is convenient in greenhouse conditions; it not only loosens the soil, but also saturates it with oxygen.
Considering that this device is made with high-quality assembly, it is durable, which cannot but please the user. The devices themselves really simplify the work of the summer resident and allow him to speed up his work.
Using this device, you can loosen the soil in a flower bed, flower garden, greenhouse, small beds and even around bushes and trees. On average, the device is capable of capturing soil up to 25 cm wide in one pass.
As for the disadvantages of cultivator attachments for gas trimmers, many buyers note their weight. The lack of weight of the device is the reason that, when faced with difficult soil, it may not go deep into the soil at all, but only scratch its top layer. In addition, as practice shows, with such attachments it is impossible to press the cutters to the ground. This risks the rod starting to spring back, and, as a result, the equipment quickly wears out.
If you try to press the device to the ground more strongly, the rod cannot stand it and bends, which can cause the scythe or the working attachment itself to break. The drive rod is quite long; vibrations cannot be avoided during cultivation, the magnitude of which is directly related to the length of the rod itself. In addition, it depends on the complexity of the area being processed, because the load on the discs and cutters will be greater in the case of dense soil.
Holding a vibrating tool for a long time is difficult, as is managing it. In this case, it is also worth knowing that constant work with a vibrating tool can be fraught with negative consequences for human health. For example, constant vibration can damage the blood vessels and nerves in the fingers of those who have problems with blood supply. When using a brush cutter with a cultivation attachment for a long time, problems can also occur in healthy people.
If you are going to take a hitch for cultivating land, then it is better to choose the disk option. It is equipped with a safety guard, although this makes the user's work somewhat more difficult. As for making the nozzle yourself, this process does not always give an effective result. In addition to the fact that the work of making a hitch for soil cultivation is labor-intensive, it is not always of high quality and reliable. In addition, home-made products do not always cope with turf.
Do not use the device without the protective casing. During tillage, it is necessary to ensure that not only stones, but also glass fragments do not fall on the knives themselves and protective devices. If this happens due to negligence, it is necessary to immediately stop the engine and disconnect the wire from the spark plug.
To wash the cutters, you need to remove the equipment. In addition, the device needs to be lubricated with oil from time to time. Given the sharpness of the blade, you should wear gloves. During soil cultivation, you cannot go to high speed. In order to correctly put on a protective screen with a line stop, you need to remove the stop nut from it, insert the bracket into the slot and rotate the screen until it passes through the groove of the bracket. After this, you need to tighten the wing nut tightly onto the bolt.
To install the attachment on the brush cutter, you need to remove the plug from the attachment rod. After this, the connection is made so that the locking (releasing) button fits into the recess on the hitch. The nozzle is pushed forward until the button snaps into place. Before starting the work process, you need to tighten the handle tightly by turning it clockwise. If the holes do not fit, this attachment cannot be used for your existing gas trimmer.
Depending on the type, the device may or may not have cutters. Based on this feature, it can be classified into gear or disk. Products of the first type are characterized by the presence of cutters, which are located on both sides of the drive shaft. The second options work using cutting discs. However, the presence or absence of cutters does not affect the functionality - cultivator attachments for a gasoline trimmer are purchased for loosening the soil.
The differences between varieties lie in the type of soil that the cultivator attachments themselves can handle. For example, gear-type varieties are lighter in weight, however, because of this they are not able to process difficult soil. Disc analogues can work not only with light soil. These nozzles are characterized by greater rigidity, they are stronger and more durable.
It is easier to process long beds with nozzles of this type, since in this case there are fewer turns. These devices are not universal, and therefore you need to purchase them for a specific model, because in this case everything will depend on the number of slots. Also, it is imperative to take into account the power of the trimmer itself.
