How to put a disk on a gas station. A knife installation algorithm for a trimmer for grass

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.

What knives to put on an electric and a lawn mower

Before buying and putting a knife on a motorcycle, find out what they are and in what cases are used. Today, manufacturers offer the consumer a large number of types of these supplies. In general, the entire cutting tool designed for mowing grass can be classified:

The main material for the manufacture of trimmer knives can be plastic or metal. The use of such consumables largely depends on two parameters:

For safety reasons, manufacturers do not recommend putting steel knives on electric trimmers for grass. Almost all motokos operating from the electric network and battery are equipped with plastic blades. Depending on the manufacturer, they can be a solid disk design, with several blades or in the form of a special mowing head, which provides for the installation of removable plastic blades.

Direct rod in a gasoline trimmer for grass and curved in electric

Putting a metal knife on an electric trimmer for grass does not allow its design features.

  • The curved rod of the unit reduces the distance from its working part to the legs of the Kosar. In the case of a collision of blades with a stone or other hard object of a braid for grass, it is discarded to the legs.
  • The high torque, which we mentioned above, in the event of a collision of a metal knife with a solid object, transfers a large load to the flexible shaft of a trimmer for grass and its engine. What causes their premature failure.
  • Handle Electric Knules most often does not have a restrictive bar playing the role of the stop. Which does not exclude leg injury.

It is these features that allow the use of exclusively plastic knives on trimmers with electric engines. In a collision with an obstacle, the blades are destroyed, thereby protecting the legs of the mower from obtaining possible injuries.

Plastic knives cope well with outgrown and dry grass. They can mow the nettles and stems of burdocks.

The use of metal knives only on gasoline trimmers is also due to constructive features.

  • The direct design of the rod increases the distance to the legs, which provides the Cossacks with complete safety.
  • Comfortable U-shaped and J-shaped handles allow you to keep the tool firmly. D-shaped handles Motokos are equipped with a limiter resting in the leg of the Costsa, which does not allow to let the head to the legs when meeting a cutting disk with a solid obstacle.
  • The clutch of the gasoline engine allows you to smoothly gain speed to the optimal level. And when the blade collides against a hard surface, it can extinguish part of the blow.

Thus, gasoline trimmers for grass with an installed metal knife are best used in large areas. They will successfully cope not only with high coarse grass, weeds, burdocks and nettles, but also with shrubs, as well as young trees.

The shape of the blades of the disk set to the trimmer for the grass does not affect the quality of the work performed. The speed does not depend on them. Triangular, trapezoid, rectangular forms are all marketing course of manufacturers.

If you plan to prepare hay, then it is best to put knives on a motorcycle with a large number of blades. Pay attention to the wheels with eight teeth or discs with four large blades and four additional. Two and three lobed knives will greatly grind the grass.

Disk selection criteria

You need to choose a plastic or metal knife, given the area of ​​the site that is planned to be processed, as well as the type of trimmer for grass is electric or gasoline. The number of blades will depend on which shoots must be removed using the tool. Choose the desired disk shape, the number of blades and manufacturing material can be using the instructions for the operation of the device. It usually prescribes which mills are recommended to use to solve certain problems.

Material

It is not recommended to put metal knives on electrocos, since the design features make their use dangerous for the user. This is due to the curved shape of the bar, the absence of stops on the handles, as well as a high speed of rotation.

On trimmers with a flexible bar in terms of safety, plastic knives should be used. Their purpose is a mowing of soft grasses, dry. Whereas metal disks do a great job with high, thick, hard shoots, shrubs, as well as shoots of trees.

Blades

The number of blades is important in solving diverse problems. So, two to three pieces are enough to grind the grass

For hay harvesting, it is necessary that there are four to eight blades on the disk. To destroy small shoots of trees and shrubs, instead of blades on the discs, there should be a large number of small teeth.

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. 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.

Installation of a disk on a trimmer for grass and compliance with safety measures

After you have decided which disk is to take for a trimmer for grass, you need to learn how to install it correctly. Initially, make sure that the landing hole on the disk is the right hole, otherwise the disk simply does not fit your trimmer. And if you manage to fix it on the tool, during operation the disk can jump off and seriously injure you.

disk, knife, installation, trimmer, grass

If a disk metal, it can only be installed on a trimmer for grass with a flat bar, since this is due to the design features of the unit design. When mowing grass, bushes and thin trees, disk, Backing on an obstacle (for example, on a stone), bounces back, that is, in your direction. And when the bar is straight, the distance from the head to the legs is sufficient for your safety.

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.

It is interesting! Manufacturers produce metal disks with an outer diameter of 220 to 255 mm.

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.

It is worth immediately making a reservation that the operation of electric trimmers is completely eliminated in the rain, wet and raw weather. This can lead to a short circuit and shock. You can not use an electrical appliance and after the rain, you must wait until the lawn grass is ventilated and dry out. However, with gasoline motorcycles, everything is also not as smooth as we would like. Some well.Known manufacturers prohibit the use of their models in the rain, as power units do not have the necessary degree of protection against moisture.

It is also impossible to operate wet equipment. If the braid for the grass was some (albeit short) time in the rain, then it must be brought into a dry place, wiped and give time to dry before starting the launch.

Some experts say that gasoline trimmers can be mowed without stopping, even if it is easy to rain. Of course, this is not recommended to do this, because the likelihood of breakdown of various nodes and the engine itself increases. Electric trimmer for grass with the upper location of the engine is less sensitive to moisture, but it is not insured from a jump in the voltage due to the water extension cord of the water. You can limit yourself to the purchase of a new extension cord, but the repair or replacement of the trimmer itself for grass is not cheap pleasure.

Testing in practice

For safety, you need to put on a protective helmet with a transparent shot to protect your face, gloves on your hands. First, we try to remove thin dry branches, gradually moving to larger ones, and finish testing dry and semi-dry trunks of trees with a diameter of 7-8 cm.

We are convinced that a trimmer for grass with a diamond disk works quite efficiently, reliably and safe. Slices, both transverse and oblique, are very smooth. They are not visible crumpled and torn fibers of wood. To mow grass with a diamond disk is also quite comfortable, effective and productively, regardless of its height, density and degree of dryness. So, a trimmer for grass with a saw disk not only perfectly performs its direct functions (Kosba of grass), but also expands the scope (removal of knots and branches from trees, and cutting non.Weed trunks). Attention! You should not get carried away by installing a large diameter and thickness for grass for grass, since this will cause an increase in the load on the gearbox and engine, and possible premature breakdown. The safety of work with such a tool will also decrease, which cannot be allowed in any case.

Modernization of a trimmer for grass: how to change a fishing line for a trimmer for a saw disk

Trimmer for grass is a simple and very useful tool in the household, with which you can mow grass and cut shrubs. Most often, a trimmer for grass has a nozzle from fishing line, less often a plastic or metal knife is installed instead of it. The latter significantly increases the functionality of the tool and expands its capabilities. However, you can go even further

So, in order to modernize a trimmer for grass, it is necessary to choose a suitable diamond saw disc from the TST series. These discs are designed to work with plywood and wood. The disk should have the following characteristics: the outer diameter according to the tops of the teeth is 216 mm, the number of teeth is 48, the landing hole is 30 mm. There must be three rings with the same external and different internal diameter in the kit with the disk. They are needed to compensate for the difference between the landing hole and the response element on the clip puck.

It is not at all difficult to install a diamond disk on a trimmer for grass. This operation is no different from the installation of any other nozzle, except that you should show increased attention and accuracy. First you need to remove the coil with a fishing line, blocking the gear shaft with a special pin with a special pin. The container for the fishing line should be rotated counterclockwise. Before installing the saw disk, we convince that its hole is more than the diameter of the sedimentary belt on the puck.

After that, you should alternately try on compensating washers and choose the one that not only fits the width, but also completely selects the gap between the centering belt of the lower washer and the landing site of the saw disk. First, the lower washer with a compensation ring is first installed on the gear shaft, then the diamond disk, after the upper washer and only after that is a protective cup. Do not forget to pull the entire package on the gear shaft with a nut.
