Is it dangerous to mow a trimmer with a disk. Choosing the best option for a cutting knife for a lawn mower

Criteria for choosing discs for trimmers for grass and instructions for replacing them

Trammers’ grass ugos occurs due to the use of a mowing head with a fishing line and metal disks. Each type of cutting device has its own fundamental features. The use of the fishing line is limited to the type of vegetation, therefore, where the head with the cord does not cope with the task, a metal disk is used. How to choose a cutting disk for a trimmer for grass, what they are, and how they are hidden, we find out the details before buying an appropriate equipment.

Initially, we note that metal discs can be used not only on gasoline, but also electric trimmers. The main condition for the use of metal cutting knives on the equipment. in the design of the tool, the transmission mechanism (shaft or gearbox) should be a rigid type. A hard.type gearbox is a metal shaft transmitting a torque from an electric or gasoline engine to a working organ.

There are models of trimmers with flexible shafts, the design of gearboxes in which is represented by a steel cable. These are, as a rule, low.power electrical grass drivers that are not intended for large loads, as well as household lawn mowers. You can’t use metal disks on trimmers with a flexible shaft (only plastic), as this will lead to a rapid failure of the gearbox. Before buying metal cutting mills, you will need to find out the type of gear ratio of your tool. hard or flexible.

What type of gear ratio is used on the trimmer is indicated in the technical description to the tool. If a trimmer for grass has a curved bar, then a flexible shaft is used in its design. Tools with direct bar can be equipped with rigid and flexible gearboxes, which depends on the power of the trimmer for the grass.

Trimmer knives are classified according to the following signs:

• Manufacturing material. they are plastic and metal. Plastic knives are less effective than metal, but they do not have a large load on the shaft and the drive mechanism of the tool. Plastic discs are used on electric trimmers and household benzos
• The design of cutting devices. Steel discs are of two types. blade and toothed (milling). Plastic knives are produced in the form of blades. Tough devices have a similar design with circular discs, and lobed have large flat knives
• The number of cutting edges. The number of teeth and knives on the disks differs, which affects the performance of cutting equipment. On gear discs, the amount reaches 80 links, and on blade. from one to four pieces
• The presence of additional spraying. steel gears are additionally equipped with winning attacks, which allows you to use a tool for driving grass on mound surfaces. When the disk is contacted with obstacles in the form of earth and stones, the teeth are not deformed and do not dull, which is achieved due to the presence of winning attacks. Experts say that devices with carbide attacks do not serve for long. Attacks wear out quickly, and then the milling cutter is used without winning

Plastic knives for trimmers not only cost cheaper than metal ones, but also do not have high loads on the engine and transmission mechanism. This is especially true when the knife stumbles upon obstacles. The higher the elasticity of the cutting knife, the less likely the deformation of the plastic disks.

It is interesting! Rosted wheels with a large number of links are used to prick different grass. dry, green lawn and thick.nisted. The cut with such a disk is straight, clean and even. In addition, a large number of teeth excludes their rapid dullness, and the presence of additional holes on the surface of the circle (penetration) is intended not only for cooling, but also to reduce weight and increase inertia.

The advantages of trimmer disks compared to the fishing line

Trimmer disk compared to the cord, has its advantages. You need to know these advantages in order to decide in the end whether to buy and use metal cutting knives. Consider all the advantages of the trimmer disks:

• The ability to cope with different vegetation, unlike fishing line. It can be dry, long and thick.nisted grass, and even small vegetation. The fishing line for a trimmer hardly copes with medium.sized grass, and it is not able to cut off thick.stubble grass. The cord will either get confused for the grass, or the fishing line for the trimmer will wear out quickly, which is not at all rational
• High speed achievement of the result. Unlike fishing line, the disk cuts grass with qualitatively (with good sharpening), without leaving “roosters”, therefore, a mowing trimmer with a metal circle occurs faster than when using the cord
• Discs do not wear out, unlike the cord. The cutting knives or parts of the circle are blunted, but the issue is resolved by hiding. How to sharpen a trimmer metal circle described in the material below. With prolonged operation, the cutting devices are abrasion, but they are enough for at least 3-5 years
• A long service life, in contrast to the fishing line, which is associated with the design of the equipment

There are also disadvantages of the considered cutting devices for trimmers. The first drawback is that it is impossible to work with a disk tool when the grass is performed next to obstacles in the form of trees, buildings, stones, shops, etc.P. When a disk collision with an obstacle, the drive is inhibition, which is reflected in the form of such minuses:

• The engine overheats
• The cutting parts of the disk that are blunted are damaged
• Transfer mechanisms. flexible and hard shafts (gearbox) come out of order

If you plan to mow thick grass in the field, then do without a trimmer for grass with an installed metal disk, it is impossible. The fishing line for a trimmer is used to prick small grass in personalities near obstacles.

It is interesting! On trimmers with a curved rod structure, you can not use steel discs due to safety. If the disk attaches an obstacle, then the effect of returns arises, through which the cutting part can fall under the feet of the operator. As a result, the operator risks getting serious injury.

What types of trimmer knives are

Initially, we note that metal discs can be used not only on gasoline, but also electric trimmers. The main condition for the use of metal cutting knives on the equipment. in the design of the tool, the transmission mechanism (shaft or gearbox) should be a rigid type.

Trimmer for grass on wheels with your own hands

Recently stumbled upon a video in which the author turned a trimmer for grass into a lawn mower, simply installing the wheels on it. He used this idea and improved his instrument, just the support wheels from the granddaughter of the bike were just useful.

When kosbe, a trimmer for grass should be kept at an angle of about 45 degrees, relative to the ground. Given this, as well as the length of the instrument bar, from the profile metal pipe cut a blank length of 50 cm.

At one end of it, on two opposite walls, the holes drilled! 12 mm. To the end of the second welded a squeezing clamp. The latter made from a segment of a metal pipe a little more than the diameter of the trimmer rod diameter for grass.

To the finished iron rack from the side of the hole with a bolt with a nut M12, twisted two wheels. He fixed the stand on the trimmer, pulling the compressive clamp with bolts. This method of fastening is convenient in that the rack can be fixed at any convenient distance from the working part of the tool.

As a result of such refinement, it became much easier to control the trimmer and the hand does not get tired.

How to fix a disk or a fishing line for a trimmer on a trimmer

The cutting mill is attached to the executive organ. The mounting location is called a gearbox. It is not difficult to cope with the task of installing a disk or coil. The principle of consolidating cutting discs on the trimmer is as follows:

• The figured washer is originally fixed by using a hexagonal key
• On the shaft set the disk
• Then install the upper washer, and then tighten it by means of the fastener
• It is necessary to rotate the nut through a special end key, which is usually equipped with each tool
• The rotation of the nut is carried out in the direction counterclockwise
• When rotating, it is necessary to jam the shaft with a hexagonal key

In the opposite sequence, the disk on the trimmer is removed and replaced. details on how to install a coil with a fishing line on a lawn mower is described in this material.

Gasoline gas mowing gasoline with butter

Before mowing grass with a benzo.leggos, it is necessary to season the tool with fuel. As fuel, gasoline with butter is used. However, take into account that mixing gasoline with oil is needed only for two.stroke engines. Four.stroke engines operate on pure gasoline, since their design has a separate container. oil crankcase. There are no 2-stroke gas crankcases in the design of the 2-stroke gasolimers, so you need to pour exclusively gasoline with oil into the tank.

As gasoline, it is recommended to use AI-92 brand fuel. In order not to make a mistake in choosing, you need to read the instructions offered by the manufacturer. Often, most manufacturers recommend using the AI-92 brand fuel, and only some recommend filling AI-95.

Gasoline must be diluted with a small one in a proportion of 1 to 25. This means that 40 ml of two.stroke oil must be added per 1 liter of gasoline. However, not everything is so unambiguous here. The proportion 1 to 25 is universal, but each tool model has its own values. These values ​​are also indicated by the manufacturer in the instructions. details about how to properly dilute gasoline with butter into a lawn mower is described here. After breeding gasoline with butter, pour a full tank, and start work.

It is interesting! If a four.stroke lawn mower is refuel, then pure gasoline must be poured into the tank, and engine oil is added to the oil container to the maximum level.

Features of electric trimmers

The lineup of electrical devices for mowing grass includes trimmers for grass with the upper and lower engine location.

If the motor is located in the lower part of the trimmer for the grass, then this device is ideal for eliminating soft and dry grass on the lawns. A feature of the under consideration of the trimmer for grass is a short mode of functioning, which makes it impossible to perform significant volumes of work.

Trimmer for gasoline grass: types and principle of operation

Gasoline trimmers for grass, depending on the scope of use, are divided into:

The trimmer for the grass of the first species is used exclusively to satisfy everyday needs, that is, it is in the household house of the summer resident. Advantages: small weight, small dimensions, the presence of a two.stroke motor, maneuverability that a flexible shaft provides. Disadvantages: impractical, inconvenience of operation due to the irrational location of the control panel and buttons, designed to perform small volumes of work, the minimum period of continuous functioning.

A professional trimmer for grass is a device that has the most improved technical characteristics. Advantages: Reliability; high engine power indicators; can mow grass, bushes, thick weeds; equipped with an antivibration system, which allows you to reduce the load on hand; As a rule, a shoulder belt includes in the kit; Ease of use. Disadvantages: high performance of fuel consumption and lubricants, careful care is required. This is a trimmer for grass,

A universal trimmer for grass is ideal for working in summer cottages, and its technical characteristics are between the domestic and professional types of device. This is, so to speak, the middle ground. Advantages: average price, versatility of use (removal of herbal cover, herbs mowing to a certain level). Disadvantages: a high level of service is required; For a short time of continuous work.

The best trimmer for grass in the assortment series of gasoline. lawn mower. She can perfectly cope even with the most serious tasks: to eliminate shrubs or shoots of young trees. Advantages: high power indicators (from 3 “horses”), the presence of several nozzles, ease of use, continuous operation for a long time, is equipped with an antivibration system and shoulder girdle.

Lawn mowed. trimmer for grass,

Why is a gas cocker?

The reasons why the trimmer for grass does not start can be a lot.

Most often, the reasons for the difficult launch are:

• Fuel quality problems;
• candy malfunction;
• pollution of air and fuel filters;
• problems with leveling pressure in the gas tank;
• Falf in the graduation channel.

Most often these malfunctions are not critical and they can be eliminated independently. Let’s consider in more detail how to do it.

Do not save on combustible for your technique, use only high.quality gasoline and oil. Strictly adhere to the recommended proportions for the fuel mixture. Also, you should not leave fuel in the tank for a long time. it over time is flooded and loses its properties.

Candles and candle channel

If you suspect a malfunction of the spark plugs, you should immediately unscrew the old candle and replace it with a new. If there is no possibility to instantly install a new candle. thoroughly clean and dry the old. Drain excess fuel through the candle channel and dry it thoroughly. After that, plunge the candle into place, set the gap 1 mm and try to start the braid again.

If the proposed manipulations did not give the desired result. check the contact of the candle. Also, the reason for the lack of a spark may be a faulty ignition unit, which is unlikely to repair it independently.

Air and fuel filter

Pollution of these assemblies of the lawn mower is fraught with either their complete replacement, or thorough cleaning. When replacing the fuel filter, do not leave a suction pipe without protection. this can provoke a breakdown in the piston system of the engine.

Problems with leveling pressure in the gas tank

This malfunction is associated with the contamination of the soundtress. When this part is salted, a vacuum forms in the gas tank, which prevents fuel supply. You can clean the soundtress using a conventional needle.

If, after checking the data of the trimmer systems for the grass, he did not start, most likely, the reason for problems with the carburetor (clogged nozzles, disturbed tightness) or engine (wear of piston rings, chips on the cylinder). Repair of this type can also be carried out independently, but it is better to trust the specialists of the service center.

Description of a trimmer for grass for haircuts of a lawn

The trimmer for grass is essentially an electric oblique. It looks like a long pole, at one end of which there is a haircut mechanism, and on the other. a handle for holding the tool. The engine can be both in the upper and lower part of the pole. it depends on whether the gasoline trimmer for grass or electric.

These tools for cutting grass are:

Did you know? Trimmer for the grass was invented by a businessman from Texas. He was far from technical developments and had been engaged in show business all his life.

The effectiveness of the described device depends on:

The principle of operation of a trimmer for the grass is simple. a drive, gasoline or electric, twists a bobbin into which the fishing line for a trimmer and a reel are mounted. The ends of the fishing line, peering out, straighten and act like blades when rotation. The thickness of the fishing line can change. from 1 mm for constant weekly mowing up to 4 mm for especially overgrown sites.

The electric tool has a number of advantages and disadvantages.

• Its pluses can be called:
• almost silent work;
• Lightness of the tool;
• simplicity in management;
• Consumable material is only a fishing line for a trimmer.

• The disadvantages of such tools are:
• dependence on the length of the cord and the electric socket;
• small power;
• Prohibition of work with wet grass.

Also, during mowing, you have to monitor the cable that can fall under the cutting part of the tool. If the plot is strongly overgrown, then in one call the grass does not cut. You should go through the area several times, removing 10-15 cm.

Important! For especially overgrown sites with high herbal cover, you should choose the models of trimmers equipped with drives with sharp teeth.

Battery trimmers for grass are relatives of electrical. They differ in that they do not need to be connected to the network. only the battery should be charged. However, a similar tool can work for 25-30 minutes.

During this time, you can have time to mow a plot of 100 m². Then the device will have to be charged, and this takes from 5 to 10 hours. As an option, you can buy several spare batteries and extend mowing for 1-2 hours.

Gasoline trimmers for grass use expensive fuel today. If the owner has no problems with the purchase of gasoline, then you can opt for this option. It is more powerful and not limited by the battery ability.

Such a tool can be mowed until the fuel ends or the fishing line for the trimmer ends. In addition, similar trimmers for grass working on a mixture of gasoline and oil are much more powerful than electric. A similar unit can be cut off on a section of up to 1000 m².

There are two disadvantages of gasoline braids for grass. a lot of noise and exhaust gases. In addition, if you do not comply with the correct composition of the mixture, the device can be launched with problems. Wheel gasoline trimmers for grass is almost a lawn mower. Two large wheels are mounted on them, which improve controllability and cross.country ability on especially difficult sites.

Tall grass mowing using fishing line

For thick stems of grass (weeds), a more powerful trimmer for grass with thick fishing line is used. However, in areas where large weeds grow, the soil is often uneven. Catching up for clods of the earth, the engine of the trimmer for the grass will sharply brake. By abusing this, you can easily damage the engine. Sowing the upper tier, you will see where the grass reaches the greatest length. in deeper places. Focusing on such “height changes”, you equal the “haircut” of the lawn, bringing it closer to the ideal.

The mowed grass is suitable both on hay and on the top dressing of the lawn. At the same time, the course of mowing grass is easier to plan, and the process will go faster.

Tips for the muzzle of high herbal are in the following.

• The engine should not overload.
• When the fishing line is confused on uneven ground or in high grass, immediately turn off the motor.
• When using gasoline or diesel as an energy carrier, you cannot mow wet grass.
• You need to move the trimmer for the grass right in front of you and left, t. to. Small grass falls on the previously processed sector. Thus, the upper tier of the grass is cut off. The lower layers are captured when you have already gone in the opposite direction.
• If the processed area is very large, mow one conditional zone after another, to which you divided the territory before work.
• Move precisely on the outside, so as not to trample the mowed grass, making your result inconspicuous.
• Moving lines should be located parallel to each other. This will easily circumvent the trees found on the site, while overload of the motor is excluded.

Subject to these recommendations, the grass will not fly to the sides during operation, and the process itself will simplify and accelerate several times.

Technique of work with fishing line and disk

The technique of work with a trimmer with a string and a disk has some differences. So, the fishing line for the trimmer cuts the grass with the very end, but with too fast the movement is used for the entire length. As a result, the stems are not cut, and the grass is wound on the cord, which is why the engine is overloaded. Therefore, you need to choose the optimal wiring speed. In addition, when mowing high and hard grass, a fishing line for a trimmer is consumed faster than when cutting the lawn.

On a note! If you need to process the slope of the hill, its peak should always be on the right. You need to rise gradually at a distance equal to the width of the scope.

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

• It is convenient to bite the garden paths, flower beds and the edges of the Lujaiks with a trimmer with an engine below. The plane of rotation of the coil of such a device can be placed perpendicular to the ground.
• Thick thickets, large weeds, bushes must be mowed with disks or special nozzles.
• When cleaning large areas, the device must be tilted to the left, in the direction of scope.
• To mow grass around flower beds, shrubs and other objects, you should rotate the head of the trimmer for the grass with a casing to them. So it will turn out to bake objects themselves and not damage them.

It should be remembered that the bobbin or the disk should not touch the ground and any obstacles except grass and branches that need to be cut off.

Care for the device

In order for the lawn mower to serve for a long time and properly, you need to perform a number of activities to care for it.

• Trimmer for grass must be stored in a dry room.
• After each use, the device must be cleaned of grass and litter.
• Air filter and a cooler radiator grille on the engine of a gasoline trimmer for the grass must be periodically cleaned by the method described in the instructions for the technique.
• It is necessary to monitor the presence of lubrication in the gearbox.
• The wires of electric trimmers should be intact, without creases and cracks in isolation. You need to include devices in the network only through groove outlets.
• All cables after use should be reelled.

If the gasoline trimmer for grass is not needed for a long time, it should be empty of the tank, let it work at idle to combat fuel residues, grease the engine. The composite bar must be disassembled, and the joints should be treated with preserving lubricants to prevent the appearance of rust. All nuances of storage and care are described in detail in the user guide, which can be downloaded in case of loss.

Production material

Two materials dominate in the segment. Plastic knives are designed for a low.power tool capable of mating low weeds, chopping herbs instead of fishing line. In this case, the quality of the cut, the durability of the consumable will be higher than that of the cord. That is why many owners of household motorcycles, guided by savings, ease of use, and other objective factors recommend that instead of a bobbin, to install discs. Before buying a plastic cutter, it should be borne in mind that it is not suitable for trimming wet grass.

The steel disk is more reliable, more effective than plastic analogues. But it can only be put on an electric trimmer for grass with a capacity of more than 1000 watts or on a lawn mower. As a rule, the consumable is available from steel or carbon alloy. The first option is cheaper, the second is easier, it will last longer. To improve consumer properties, manufacturers often enhance the teeth and blades of attack from the winnet, which improves the quality of the cut, reduces wear. The metal cutter is used in professional technology, is able to effectively pump out any grass regardless of stiffness, volume, stop young shoots, including after rain, watering, cut shrubs, even small trees, if the pillar diameter does not exceed 70 mm.

Another criterion affecting the reliability of the cutting element is the production method. Knives are forged or stamped. The first is characterized by increased strength, chips are not formed on it, with direct contact with the stone of such a cutter there is more chances to stay whole. The second option is inferior in quality, but it is also much cheaper. It can be advised to owners of even areas where there are no stones, there are no solid items with which random contact of the cutting milling cutter is possible.

Design features

Motokos owners are invited to use disks of various shapes:

Lobed

The tool has the shape of a star with two, three, four knives. There are exotic models with a large number of rays, but they, as a rule, are not popular among gardeners. A lobed disc for a trimmer for grass is characterized by a lightweight, reduced inertial moment. As a result, it less loads the engine and gear shaft, which allows you to install consumables even on medium.power garden inventory. The main scope: pruning of large weeds, stopping shrubs, mowing lawns. When choosing lobed discs, it is important to look at the number of rays:

• 2. suitable for cutting soft grass of the same type. During use, the cutter actually mulches the stems. When working, shoots fly aside, so it is necessary to wear goggles and install a plastic casing when working with a trimmer.
• 3. designed for mowing high weeds. Such discs are both steel and plastic. By performance, they are better than two.lobed analogues.
• 4 and more. are used to remove dry laws, massive thickets of weeds, ragweed, hogweed. Due to the number of blades, the waste is practically not grinded, which should be considered when choosing this type of disk.

Toemed

If there is a need to mow not only the lawn on the site, but also cut shrubs, grapes, young trees as a cutting tool, it is better to choose a gear disc. In its form, it looks like a cutter, has small sharp protrusions around the edges. The number of cutters depending on the model varies in the range from 2 to 80. By the indicator, you can also determine the main purpose of the tool:

• double.toothed. used for mowing young lawns, low vegetation;
• with three incisors. for coarse grass, small dryness;
• with four teeth. to combat medium.sized shoots, weeds with a hard stem;
• Eight.pointed. used for hogweed, ragweed, other very large shoots;
• a disk with 24 teeth-suitable for trimming grapes, a young shrub;
• 40 teeth. used in high power gasoline motorcycles. It is practically identical to Freze, is able to fight any dry.resistant, cut trees with a trunk with a diameter of up to 70 mm.

Which trimmer for grass is better: with fishing line or knife

The trimmer is usually included with a trimmer and a knife, which are selected depending on the conditions of the device. So that the lawn is neatly trimmed, it is necessary to correctly select the cutting system. How to do it.

The cutting system of a trimmer for grass plays a decisive role as its work. So that the lawn is neatly trimmed, and the process of working with the device. as convenient as possible, it is necessary to choose the right cutting system correctly. The trimmer is usually included with a trimmer and a knife, which are selected depending on the conditions of the device. So, a fishing line for a trimmer is optimally suitable for mowing dry and wet grass, crushing grass in pillars, trees, fences and alignment of lawns. But the knife is best suited for germinating shrubs.

Trimmer for grass with fishing line when working a trimmer with a fishing line should know some features of functioning. So, a fishing line for a trimmer has a large capture of cutting. To reduce the level of load on the engine, during a mowing, the coil with a fishing line must be kept strictly parallel to the ground. The distance between the coil and the ground should be about 5-10 cm. If you had to deal with very high grass, then it is better to mow the tops first first. Only after that you can mow the rest of the grass. Otherwise, the tool may jam.

To improve the effect of the device, experts recommend that the bone of the grass in the direction of rotation of the coil with a fishing line. In addition, the grass will fly aside the opposite from you. When working along the fence and walls, it is best to mow the grass with the tip of the fishing line so that the engine does not overload.

A trimmer for grass with a knife trimmer for grass with a knife easily copes with high hard grass and even small shrubs. The design of the knife affects the quality and speed of the cut. There are knives with 2-4 blades. So, the more blades, the faster and better the trimmer for the grass will work.

The diameter of the cutting knife is also of particular importance. Experts recommend choosing large diameter knives to remove non.weed young trees and shrubs. If it is necessary to mow grass, but useful plants grow next to it, then it is worth choosing knives with a minimum diameter. Thus, you will be able to carefully circumvent the plants without damaging them.

So, to say which trimmer for grass is better, with a fishing line or a knife, since they are designed to perform different tasks. For aligning lawns and mowing grass, we recommend buying a trimmer for grass with fishing line. But if, on your site there are shrubs that need to be removed or high grass, then the model with a knife is the best option. However, we suggest you pay attention to the models of Energomash GK-35120D, Baumaster BT-8925X, StURM BT8952D, which are included in both the trimmer fishing line and knife.
