A knife for a trimmer for grass which side. Disk selection criteria
Rules for replacing knives on a trimmer for grass
If the disk on the trimmer is used regularly, it needs to be removed from time to time to remove and sharpen or change it to a new. This part can be made of metal or plastic, have a different number of blades, but the replacement process remains the same. over, this procedure is similar to the equipment of different manufacturers, whether Carver or Huter, but minor differences are possible. Changing the knife on the trimmer is quite simple if you observe safety precautions and know the correct procedure for which you can find a description of which you can in the user’s instructions. The whole process of replacing step by step, as well as the way of independent sharpening of knives, will be described in this material.
When using motorcycles in summer cottages, the most popular nozzle is a fishing line for a trimmer. It has a small price, suitable for different trimmer heads, is safe when working. The minus of the application of the fishing line is that it is convenient only for the bevel of low shoots. In other situations, the string is immediately clogged, regardless of whether the gasoline or electric model of the trimmer for grass is used. In addition, vegetation is wound on a spindle, which creates significant resistance on the shaft and leads to its breakdown. It can also provoke a failure of the piston system in benzocos or burning out the motor in electrimmers.
Therefore, for mowing high or hard vegetation, various nozzles are used. So, for harvesting tall and rough grass, thin shoots of trees and shrubs to install and use it better. This nozzle clogs much less often, which contributes to the greater wear resistance of technology.
On a note! Due to the fact that the engine of electrical and battery models is less powerful than on benzocos, so the use of discs is more relevant for gasoline braids.
Features of disks for motorcycle
Disks-ceremonies are produced by plastic and metal, as well as various shapes to perform diverse tasks.
- Two-, three- and four-lobed knives with pronounced blades are used for mowing grass and overgrown trees. However, they are not suitable for harvesting hay, as the shoots are crushed, cutting them several times.
- Massive four.lobed discs are intended not only for clearing the earth from grass, but also for hay mowing. They prevent multiple cutting of shoots, thereby making them suitable for harvesting for the winter.
- Disks with cutting faces around the perimeter are relevant for the bevel of reed and reeds. Such knives are very heavy. this is the necessary quality to cut thick stems.
- Professional discs with a saw tooth for artisans and motorcycles allow you to cut down small trees and bushes.
Plastic knives are used as an alternative to metal disks. They do not need to be tightly attached in the head, and they revolve as a result of exposure to centrifugal force. The strength of the plastic knives is high, so the service life is quite long.
On a note! The advantage of plastic disks lies in the fact that, having hit an irresistible obstacle, they bounce, and there is no re.contact.
Types of heads for trimmers
A trimmer is a tool that is used to combat vegetation in a summer cottage or household territory. Grassing and hay harvesting for cattle implies the use of benzo or motorcycle. The heads of different types are installed on trimmers for the grass, through which the grass and other vegetation occurs.
The heads are classified into three main types that differ not only in design, but even in price, the method of operation and service life. Consider all types of heads for trimmers, as well as their technical features.
Manual or mechanical coils their purpose and application
The first trimmers for grass were produced with manual types of coils that have a primitive design. They consist of a plastic or metal disk in which there are holes for fixing the fishing line. The holes have the corresponding size, which allows the cord (fishing line for a trimmer) of a certain diameter. However, this is not the only drawback of equipment, since another minus is the need for frequent fishing line refueling. Below is a variant of the simplest coil with a fishing line for a trimmer for grass.
Following the simplest coils, mechanical head heads appeared, inside which a bob is installed with a fishing rod. Such devices are excluded deficiency of the fast consumption of the cord, however, to serve a new fishing line, you should interrupt the work on the injection of grass. To supply the cord, the head is equipped with a manual regulator, through which the fishing line stretches. Today, the manual type models are rarely used, which is associated with their great drawback. the need to interrupt the work and drown out the engine in order to lengthen the cord.
Review of manufacturers
Motokos disks manufacturers are a huge number. It is worth familiarizing yourself with the most popular among them. For example, the Bosch brand is known for its knives with two and three blades. The peculiarity of the knives of this company is that each of the blades can be replaced separately from the others.
Another company, known for its lobed knives, is a “shark”. The advantage of the design is that the blades are fixed relative to each other at an angle of 120 degrees. As a result, it is easy to configure each of the blades, which is convenient for different vegetation. Another feature of the knives from this manufacturer is small weight.
Husqvarna is also known for its knives with many teeth, especially hay knives. Ideal for thick and dense grass. Of the minuses, it is worth noting the large weight of the disks and the fact that you can not turn the knife if one side is imprisoned.
InForce knives cope well with undergrowth and branches. In practice, the metal from which the cutting elements are made shows itself as a very strong. The only thing in some models of winning attacks are erased very quickly.
Positive reviews often receive knives from Maruama. They are characterized as very strong and durable.
Discs do equally well as grass of different types, so with shrubs and trees.
Rezer discs perfectly cut grass, weeds, branches. The teeth can withstand even drilling trees with a thickness of 6 or more centimeters. However, they have a lack of winding grass on the shaft.
Patriot company produces high.quality knives. Users note that if you choose the right disk for a certain job, then it will serve for a long time and surprise with its performance. It is very easy to drag knives from this manufacturer on your own.
How to choose?
When choosing a knife for a mower, you should pay attention to many points. For example, wheels with metal teeth are most often made in the form of a circle. Teeth can differ in shape, species, size. For small trees, as well as thick grass, it is better to give preference to discs with a large number of teeth.
It is worth noting such an advantage of milling circles for motorcycle, such as a quick speed set. However, the high moment of inertia does not affect the drive device of the unit in the best way. For dense mowing, for high, as well as for small rough grass and shrubs, it is better to choose circles with 40 or more teeth and peoration. They are able not to grind vegetation, and at the same time it will practically not be wrapped in a circle. If the number of teeth is more than 60, then you can safely use for grass and trees with a barrel thickness up to 7 cm.
Disks with a solid canvas and without holes are distinguished by a large mass, so they should be chosen for powerful trimmers (more than 40 cm3). At the same time, it is convenient for them to mow rare grass, dry, they are also suitable for mowing with different densities.
Winter attacks should be chosen for mowing plants next to obstacles. If you need to mow grass on hay, then you should give preference to steel knives with a large number of teeth with even sharpening. Continuous discs with the number of teeth from 16 to 32 cut plants well with thick stems.
For low.power trimmers, lobed discs with a minimum moment of inertia are better suited. The smaller the blades, the stronger the tool will grind the grass. So, discs with two blades are most often used to mow homogeneous grass. The main advantage of this species is that it discards cut plants to the side.
When harvesting hay, it is recommended to choose knives with four blades so that the grass does not grind.
The thickness of the blades is also important when choosing. Discs can be stamped or forged. The former are characterized by a low price, but at the same time can be badly damaged, faced with an obstacle. As for the forged discs, chips and slices do not form on them in a collision with solid objects.
For electric trimmers, only plastic knives should be selected. Their low weight will not create an excessive load on the engine. Soft plastic allows the knives when they are on the obstacle do not break, but simply bend slightly or deform. It is recommended to use such cutting elements for beating thick soft grass.
How to put a knife on a trimmer for grass correctly
Putting a knife on a trimmer for grass is not so difficult. The manufacturer equips his tools with a special pin that allows you to block the gearbox and the key, with which the spool is unscrewed with the fishing line.
The most important thing is to observe when changing the cutting elements safety precautions and the assembly sequence of disassembly.
The algorithm for installing a knife on a trimmer for the grass is as follows:
Alternative method for installing a knife
As you can see, there is nothing complicated. Now you can safely start the mowing of weeds on the site.
Haircut of various types of vegetation
In addition to holding the knife parallel to the ground and cutting more dense thickets with the left side of the knife, there are some tips that should be taken into account for each type of vegetation that you may encounter:
Grass and weeds
To cut the beams of herbs and weeds, make sweeping moves forward and back with long arcs, as if you used a braid. Keep a trimmer for the grass so that the knife barely soars above the ground.
Cutting thick, thick bushes, starting from the base of the plant, is not the easiest way. Instead, start by raising the knife to about the waist level, holding it parallel to the ground. Slowly lower it until the knife is right above the ground. Never raise a knife above the level of the belt.
Small trees and seedlings
A trimmer for grass with a saw can be used for cutting trees with a diameter of up to 2.5 cm. For trees of larger diameter, use a chainsaw.
Keep a trimmer for the grass so that the knife is at an altitude of 5-15 cm above the ground. Take a stable position and press the left side of the knife to the right side of the tree. Cut evenly, without shocks.
- Inside, the coil will show how many recesses to wrap (two or one). If there is one recess, both ends of the threads will be laid along this recess. If there are two of them, the antennas are laid out separately. each in its depths.
- It is necessary to rewind from 2 to 4 meters of polyethylene thread and plunge it with two ends into the hole.
- Wrap both threads in the same direction as the drum.
- When all the hair is wound, the ends should be fixed in the grooves or hold on.
- Both ends are stretched from the outside of the clip body.
- After that, the drum is assembled and inserted into a mower.
Tips and steps to replace the cutting element in the video.
To insert a fishing line for a trimmer into a lawn mower with two grooves in the drum, you need to use the previous option for refueling this plastic thread. In this case, each end of the mowing fishing line of the hair will be wound along its groove. All other actions are similar to the previous process.
A coil or a roller can have a completely different design than the previous two options. A fishing line for a trimmer can be stitched through the eye, which passes inside the coil. In this case, you do not need to disassemble the roller drum and manually wrap the plastic thread.
The plastic thread is sewn through the hole and turned by pressing a special button. This button is located on the housing and is designed to operate the equipment, to be able to produce hair as it is worn.
Do not worry that the plastic thread is wound in the wrong direction, because in this design it can rotate in only one direction.
For quick and safe replacement of the cutting element on the drum mower, it is necessary to observe precautions. Before removing the coil, it is necessary to turn off the equipment from the power source (if the lawn mower works from electricity) to wind a fishing line for a trimmer on a lawn mower

Here I want to mention the rating of the reliability of electric lawn mowers, which will help you choose a reliable assistant.
Another important compliance with safety rules. Press the lock button. You can find out how it is located on the equipment case, following the instructions. For example, instructions for a gas mower can be found here.
Remember that the cutting element should be adjusted. There is a button on the block case. If the process does not start automatically and the thread tension decreases, the button is clamped, and the fishing line for the trimmer with force is pulled out of the coil.
It should be remembered that replacing the cutting element in the lawn mower. This is an important process that requires responsibility. All this must be done in stages, and only a special plastic fishing line for a trimmer must be inserted into the coil. Iron cable, high.quality wire or even an enhanced fishing line for a trimmer are not suitable here.
If there is a cottage or a large plot of land next to your house or cottage, then the lawn mower should be used for easy cleaning of grass and weeds. If you think about choosing an electric lawn mower or gasoline, click here and you will find comparative characteristics of various models.
Over time, a fishing line for a trimmer on a mower wear out and requires a replacement. This can be done independently. This polyethylene thread must be selected depending on the model of the mowing. It is also worth familiarizing yourself with the rest of the car, for example, you will find information about the blades of the Craftsman lawn mower, which also wear out and lead to irreversible consequences.
The device of the coil, into which the fishing line for a trimmer of hair growth is inserted, is very simple. But it depends on whether the coil with one or two threaded antennas is working
It is important to take precautions when replacing the coil

When choosing a knife for a mower, you should pay your attention to many points. For example, wheels with metal teeth in most cases are made in the form of a circle
Popular grass cutting blades for trimmer
Teeth can differ in shape, species, size. For small trees, it is also better to give preference to discs with a huge number of teeth.
It should be noted such an advantage of milling circles for motorcycle circuits as a frisky set of revolutions. But the highest moment of inertia does not best affect the drive device of the unit. For dense mowing, for the highest, also for small rough grass and shrubs, it is better to choose circles with 40 and more teeth and penetration. They are able not to grind vegetation, and with all this it will actually not be wrapped in a circle. If the number of teeth is more than 60, then you can safely mow grass and trees with a trunk width up to seven cm.
Disks with a solid canvas and without holes are distinguished by a large mass, so they should be chosen for massive trimmers (more than 40 cm3). With all this, it is comfortable to mow the rare grass, dry, they are also suitable for mowing with different density.
Winter attacks should be chosen for mowing plants next to obstacles. If you need to mow grass on hay, then you should give preference to iron knives with a huge number of teeth with even sharpening. Continuous discs with the number of teeth from sixteen to 30 two perfectly cut plants with thick trunks.
For low.power trimmers, lobed discs with the least moment of inertia are better suited. The smaller the blades, the stronger the tool will grind the grass. So, discs with 2 blades in most cases are used to mow homogeneous grass. The main advantage of this species is that it discards cut plants to the side.
The thickness of the blades is also fundamental when choosing. Discs can be stamped or forged. The 1st differ in a low price, but with all this they can be very damaged, faced with an obstacle. As for the forged discs, chips and slices do not form on them when colliding with hard objects.
For electronic trimmers, only plastic knives should be selected. Their low weight will not create an excess load on the engine. Soft plastic allows the knives when they are on the obstacle do not break, but simply bend a little or deform. It is recommended to use such cutting elements for a beard of thick soft grass.
When to use the disk on the trimmer instead of fishing line
What is the difference between a metal disk from the fishing line per trimmer for the grass, it is already clear. Когда же необходимо завершить кошение леской, и закрепить на триммере металлический круг. This question is popular among beginners, since if you continue to mow large and thick grass with the cord, then it will wear out quickly. This is due to the fact that the fishing line for a trimmer with high speed begins to break about thick.stubble grass, which leads to its damage and, accordingly, rapid wear.
Apply knives on the trimmer should be with the following vegetation mowing:
- High and coarse grass cover
- Storms and dryness
- Young shoots of trees up to 7 cm in diameter
- Homemade thick.stem plants like raspberries, rose hips, currants
The use of knives eliminates the rapid wear of the fishing line, and also increases the efficiency and productivity of the use of a travic tool.
Instructions for replacing a disk on a gas tank with a step.by.step description
Having sorted out the design of the cutting knives, it remains to find out the process of replacing them and installation on the tool. If there is a head with a fishing line on a gas station, and it is planned to install a metal disk, then no remodeling of the structure will be needed.
To install a metal disk on a trimmer for grass, the following instructions must be followed:
- First, a plastic protective casing is removed. it is not necessary. Depending on the model of the tool, the dismantling process may differ. If the trimmer has a metal casing, then it is not necessary to remove it. Removing a plastic casing is performed in order to install a metal
- Using a special key-player or screwdriver, it is necessary to block the gearbox. The shaft blocking hole can be located on the side or on the end side
- A mowing head or spool is twisted from the tool if they are installed
- A disk is installed in the place of the head or spray. The internal diameter of the disk should be in a special groove. The nozzle is installed so that the front side (with letters) looks upward
- After installing the disk, a fixing washer of the corresponding size is placed. After that, the mounting nut is screwed, having previously blocked the gear shaft. Direction for screwing the fastener. counterclockwise
- After completion of work, it is necessary to install a protective metal casing. If it is not, you should leave a plastic casing
As you can see, the procedure for replacing the disk on the trimmer is not at all difficult, and takes no more than 5 minutes in time. Below the video shows how to properly change the mowing heads and circles on benzocoses.
Cultivator for motorcycles. an effective replacement of shovels and traps
For loosening the soil, you can use a shovel or nozzle cultivator for a trimmer for grass. The first tool has only one plus. the ability to always maintain physical form. Now about the advantages of the cultivator for the lawn mower:
- High speed processing speed.
- Efficiency. the cultivator not only loosen the earth, but also grinds it. Immediately after cultivation, the Earth is ready to plant various cultures.
- Does not reduce the amount of black soil. Shallow cultivation helps to preserve the fertile soil layer.
- Lack of physical fatigue. The process of cultivation by the trimmer occurs similarly, like the mowing of grass.
The cultivator from the benzotrimer is used to process the soil in the aisles. swinging and weeding, so the device is also called a motorcycle. When choosing a nozzle, a cultivator for a trimmer for grass, it is important to consider the following recommendations:
- The quality of the cutting elements. choosing cheap devices, you will most likely come across the fact that when processing the sealed soil, knives will deform;
- The presence of a protective casing is an obligatory attribute, the absence of which is unsafe for the operator, since small stones and dust will fly into the face to the operator;
- sufficient weight of the device. the nozzle should have a mass of at least 5 kg, otherwise it will be discarded up from vibrations.
Such a device is used by summer residents for weeding potatoes, while scaring the ground at the same time, and removing weeds. The device justifies itself in the presence of large volumes of work, so it is recommended to evaluate the nozzle for a trimmer for grass cultivator. A significant drawback of the equipment is a significant load on the shaft and engine, so it is very important to take breaks as often as possible, and use powerful units for work.
To clean the garden path from contaminants, it is recommended to buy a brush for a shock for a lawn mower. This device is a roller roller located throughout the circle. The upper part is closed by a protective casing, which prevents the raising of pollution up.
The indisputable advantage of using such a nozzle paired with a trimmer is a high speed of achieving the result. However, you should not buy a device if a small part of the yard needs scenaries.
The rotation of the shaft with high speed promotes not only the removal of contaminants, but also the polishing of the concrete surface. You can use equipment even to sweep the leaves on the lawn, moss and other contaminants. The sweeping process is based on the scattering of garbage on the sides, cleansing only the main surface, which is the minus of this device.
It is interesting! When performing a large amount of work, it is recommended to choose products with built.in wheels.
Chips on the choice
First of all, the knife should be durable and durable. The best material for knives is stainless steel of the desired thickness, and not, for example, black steel with stainless steel or galvanized iron. Sometimes manufacturers indicate a stainless steel brand, for example, AISI 304. A knife is not the detail on which it is worth saving.
For portable lawn mowers, the minimum solution is considered to be a blade with two knives. In other words. you should choose a knife with two cutting edges. He will cut the grass. but it will not grind it. To mulch the grass. buy a cutter with eight.e likely. The optimal angle of sharpening is approximately 30 degrees. You will quickly learn to recognize such knives.
The carving of the rotor pin on which the cutter is put on with its landing holes does not matter. It is usually left if the knife spins to the right. and vice versa. This helps to avoid unscrewing the nuts and flowering the knife at full speed.
If your choice still fell on plastic knives. look for a black and rather hard plastic, which longer retains the factory severity of the cutting line. Such does not scatter into crumbs from the slightest blow when carrying or rolling the lawn mower to the place of the beginning of the mowing of grass.
Most often, the malfunctions are as follows: the braid does not download the grass or does not turn on at all.
The mower does not mow grass
- A knife is blown or broken. Sile it with a file, an angular grinder, on a sharpener (you need a plane.cylindrical sharpener) or on a machine (or drill) using sandpias. Check the balancing of the cutter.
- The cutting itself is set incorrectly. Put a gap in a cylindrical mower between a rotating cylinder and a knife blades equal to a thickness of a piece of paper.
A rotor with a knife does not spin in a mower
- The knife itself was stuck. Pull the grass and earth from under it and scroll the cutter itself. He should rotate freely, without scratching and touching the protective casing.
- The drive belt is torn. Check the integrity of the belt. A worn, “sprinkled” belt must be replaced.
- Cliff on nutrition. Restore the ragged wire in the cord. Replace the cord if the insulation is disturbed.
- The switch does not work. Check the switch performance, try to turn off and turn on the mower. If the switch is unsuitable (melted, the contacts are burned). replace it.
- The supply voltage in the network is gone. Check the possible operation of the protection machine on the electrical panel.
- The fork is not included in the outlet. Turn on the fork in the outlet (if it turned out to be pulled out).
- The fuse in the device burned down. Check it using a tester (multimeter). If necessary, replace a faulty fuse.
- The thermal protection of the braid turned off the motor. Wait for the cooling of the motor after the mowing session of the grass.
Having checked all the details and nodes, finding a malfunction, run the mower. Most likely, your problem will be solved. In fuel lawn mowers, the guilt of everything is either a carburetor (or drive) or the fuel ended. Often the unstable operation of the motor requires the search and exclude breakdowns of a number of parts, before it is possible to find and replace the faulty.
