How to put the knife on the trimmer

How to give out any knife in CS: GO. Butterfly knife, bayonet knife and others.

In the third cell of the available weapons in CS: GO, there is a knife by the standard, which is not bought and is given in each round. Without buying skins, the knife is also standard, but knife skins are expensive, sometimes even very expensive. However, there is a way to play with any of the available skins without paying a single dollar for it. How to give yourself any knife in CS: GO, we’ll tell you in this guide.

To give yourself a knife, you need to do several important steps. So, go to your server and turn on the cheat mode. This is done with the command sv_cheats 1.

The next step is to allow the knife to be thrown away, which usually cannot be done. To enable knife drop, we write mp_drop_knife_enable 1 in the console. By the way, if you replace the number one with zero, it disables the action of these console commands.

knife, trimmer

We look at the table below and choose the knife we ​​need, but attention, we look at the continuation after the table.

Knife Console command for knife
Karambit give weapon_knife_karambit
Bayonet M9 give weapon_knife_m9_bayonet
Butterfly knife give weapon_knife_butterfly

Navaja give weapon_knife_gypsy_jackknife
Stylet give weapon_knife_stiletto
Claw give weapon_knife_widowmaker

The last step, we can throw the knife away (what do we do), we can give out any knife, but how to pick it up? To do this, you need to register the last console command ent_fire weapon_knife addoutput “classname weapon_knifegg”.

Done, now we can give out any knife and play with it. A significant disadvantage is that this method works only on your own servers, or on servers with cheats enabled. If some points are not clear, then we recommend a video to get acquainted with this topic.

How to put the knife on the trimmer

With the arrival of summer, many owners of personal plots are worried about the question of how to put the knife on the trimmer. No less relevant are the questions of why and when it is advisable to replace the line on the brushcutter with a more durable cutting element. In our article we will try to disassemble all this and give useful recommendations to summer residents.

What knives to put on an electric and gas cutter

Before buying and putting a knife on the brushcutter, we will find out what they are and in what cases they are used. Today manufacturers offer the consumer a large number of types of these consumables. In general, all cutting tools designed for mowing grass can be classified:

  • By the type of material from which it is made;
  • By the shape of its cutting blades.

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

  • Type of brushcutters;
  • Mowing areas.

For safety reasons, manufacturers do not recommend putting steel knives on electric trimmers. Almost all brushcutters powered by an electrical network and a battery are equipped with plastic blades. Depending on the manufacturer, they can be of a solid disc-shaped design, with several blades or in the form of a special mowing head providing for the installation of removable plastic blades.

Straight bar for petrol trimmer and curved for electric

To put a metal knife on an electric trimmer is not allowed by its design features.
  • The curved bar of the machine reduces the distance from its working part to the mower’s feet. In the event of a collision of the blades with a stone or other solid object, the scythe is thrown to the feet.
  • The high torque we mentioned above, in the event of a metal blade hitting a hard object, transfers a large load to the trimmer flex shaft and its motor. What causes them to fail prematurely.
  • The handle of the electric scythe most often does not have a limiting bar acting as a stop. Which does not exclude injury to the legs.

It is these features that make it possible to use exclusively plastic knives on trimmers with electric motors. When colliding with an obstacle, the blades are destroyed, thereby protecting the mower’s legs from possible injury.

Plastic knives do a good job on overgrown and dry grass. They can mow nettles and burdock stalks.

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

  • Straight bar design increases leg clearance for complete safety.
  • Comfortable U-shaped and J-shaped handles provide a firm grip. The D-shaped handles of the brushcutter are equipped with a limiter that rests on the leg of the mower, which does not allow the head to come close to the feet when the cutting disc meets a solid obstacle.
  • The clutch of the gasoline engine allows for smooth acceleration to the optimum level. And when the blade hits a hard surface, it is able to absorb part of the impact.

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

The shape of the disc blades supplied to the trimmer in no way affects the quality of the work performed. Speed ​​does not depend on them either. Triangular, trapezoidal, rectangular shapes are all the marketing ploy of manufacturers.

If you plan on making hay, it is best to use knives with a large number of blades on the brushcutter. Note the discs with eight teeth, or discs with four large blades and four additional blades. Two and three bladed knives will chop the grass hard.

Why you need to put the knife on the trimmer

A trimmer with a knife mounted on it is most convenient to use for more comfortable mowing of tall and coarse grass in the country. The line on the brushcutter in such cases does not cope. Thin tears very quickly. Using 2.3mm thick cord or homemade rods with cables causes the vegetation to wrap around the spool. This increases the load on the engine. As a result, the piston group and other moving parts of the unit wear out very quickly.

If the weeds are mowed with an electric trimmer without a knife, only a fishing line, even a thick one with a curly section, will not solve the problem. There is always a risk of overheating the motor and damaging the flexible shaft. And it’s all about the large torque of the electric motor. Grass wrapped around the spindle creates strong resistance to the shaft, which resembles a speedometer cable, which does not withstand and twists.

In order to protect the equipment from premature wear, manufacturers have provided for the possibility of installing special knives on the trimmers. The design and shape of the existing cutting elements allows you to easily cope not only with coarse and overgrown grass, but also successfully deal with young shrub growth.

How to put a knife on the trimmer correctly

Putting the knife on the trimmer is not that difficult. The manufacturer completes its tools with a special pin that allows you to block the gearbox and a wrench with which the spool and fishing line are unscrewed. The most important thing is to observe safety precautions and the sequence of assembly and disassembly when changing cutting elements.

The algorithm for setting the knife to the trimmer is as follows:

  • Remove the protective cover;
  • We block the drive. To do this, it is necessary to align two holes. in the shaft hub and in the gearbox cup. After combining them, insert a pin into the holes;
  • We unscrew the spool with line or the fastening nut holding the boot (if the trimmer has not been used yet) from the hub clockwise;
  • Next, we install the cutting knife, so that the slots on the hub washer coincide with the recesses in the hole of the cutting disc;
  • Install the boot;
  • We tighten the fastening nut (counterclockwise) while holding the locking pin;
  • We tighten it using a tubular wrench;
  • Putting the protective cover back in place.

As you can see, there is nothing complicated. Now you can safely start mowing weeds on the site.

Types of steel knives

Not all brushcutters are designed to be fitted with discs or blades. In order for the engine to “pull” the knife, it must be powerful, at least 1-1.2 hp. In addition, a rigid forged shaft must be installed inside the boom. If you have a gasoline scythe or an electric trimmer with a curved bar, then inside it is not a metal shaft, but a cable. He will not stand a knife. it will burst right there.

But, if everything is in order with the scythe, and the manufacturer provides a knife in the kit, then feel free to use it.

The knife is indispensable in case:

  • mixed vegetation;
  • the presence of dense and tough growth;
  • an abundance of hard weeds;
  • cut stalks of corn, sunflower;
  • germination of fresh shrub shoots.

The cutting principle is the rotation of the knife on the shaft. The mowing width, as a rule, is standard for all brushcutters. a quarter of a meter, but there are knives and larger in diameter.

By design, the blade for the brushcutter is bladed. Blades are sharp blades that are sharpened on both sides. There can be two, three, or four blades.

  • The two-beam one resembles a plate. Lightweight and suitable even for household trimmers;
  • Three-lobed. the most popular for cutting weeds. It has a small base and three long blades;
  • The four-beam differs in that its base is larger, and the blades are shorter. With this design, less grass is cut, which is important when mowing for hay, since finely chopped hay is difficult to collect later.

The more blades, the higher the mowing performance. After all, it is the blades that effectively cut tough vegetation.

Often, to increase the strength of the knife, victorious solders are applied to the blades. Such a knife element is much stronger and more durable. But it is also heavier in weight. Therefore, do not rush to install a multi-blade knife if you mow, for example, soft clover. Better save it for vegetable gardens where you need to cut thick and tough corn stalks.

When mowing with a knife, carefully inspect the area. if there is any treacherous stone or hard bump. If you stumble upon it, you will break or warp the knife, and you will also expose the engine to unnecessary stress.

What is the best line diameter?

For grass that is different in freshness and softness, you need a different diameter of the fishing line (cord). But let’s say right away. carefully read the technical data sheet of your device. If the manufacturer has indicated that the permissible line is not more than 1.2 mm, then do not try to wind a 2 mm one. Do not mow for a long time. The engine will overheat due to load.

READ  Petrol trimmer power how to choose

The diameter of the cords for brushcutters sold in Ukraine is in the range from 1.2 mm to 4 mm.

  • 1.2mm. 1.6mm. Slim. It is used for lawn care, constant and frequent mowing. Most often recommended for electric trimmers, 0.5-0.7 kW.
  • 2 mm. 2.4 mm is the most popular cord option. Suitable for medium power units. the most common among summer residents. Cuts both young and old grass, tough and mature.
  • 3mm. 3.2mm suitable for heavy duty professional gasoline scythes. Thick strings easily handle even coarse weeds and dead wood.
  • 4 mm is the thickest. Some aluminum is added to the nylon for strength. It is rarely used, since the engine power, as a rule, puts restrictions on a given diameter. But, if the engine allows. refuel and cut the weeds.

Manufacturers often paint fishing lines of different diameters in different colors. green, blue, orange, to make it easier for users to understand. The area of ​​the bay varies from 10 meters to 100.

Which cutting system for brushcutters is better: line knife or disc

Mowing lush green grass with fishing line is easy and pleasant. Even fun. But it is worth stumbling upon dry, tough stems, and the fun will diminish. Such a task is beyond the strength of the line. It just slips, and the weeds remain intact. You need to replace it with a knife. That is why high-quality and powerful brushcutters always have a removable cutting set in the kit: fishing line, knife and disc, for example, on the website https://storgom.ua/motokosy.html you can conveniently and quickly pick up a braid with any cutting system, make sure of this ourselves, but we do not leave the topic and read on.

What to mow with a toothed disc

If a knife has eight or more blades, then it is already called a disk. The number of teeth ranges from eight to forty. The multi-tooth disc is made of strong steel. Sharpened on both sides. Its base is large, and the teeth are small and sharp. It works like a saw. it rotates and cuts. The disc must be installed especially carefully. fix it evenly and well.

The saw blade is needed for cutting thin tree trunks. Even a fully formed trunk can be cut down by carefully sawing it from different sides.

But the disc is intended not only for cutting down young growth of trees. You can easily mow them and grass for hay. Especially dry and tough. The main thing is to choose the right disc. lightweight and with a perforated base. Then the grass is not cut strongly. This is important when cutting short grass for hay.

If you are going to cut trunks, you can install a circular disc. He cuts great, especially if the teeth are slightly spread. But when installing a circular disc, you are at great risk. There is a risk of ditching your tool, since the load on the gearbox increases tenfold. A powerful engine (2-3 hp) will pull such a disk without any problems, but the gearbox. it is not clear how it will behave. Therefore, such a change can only be done if you are sure that the gearbox is durable and professional.

Section. what affects the shape of the line

The thread shape also affects the mowing result. Like the diameter, it directly depends on what exactly you will be mowing. The cutting edge is by section:

  • Round. Most common. It mows both dry grass and fresh grass well. One of its advantages is low noise, but users say that this characteristic is not important, since the growling gasoline engine drowns out all other sounds.
  • Polygonal. The section can be triangular, square and even hexagonal. The pluses of the polygon are sharp cutting edges. They better interrupt rough stems, even young shoots of a bush. Hence the highest productivity. Less. used up too quickly.
  • Figured. The section is intricate, ribbed. It looks like an asterisk or a twisted square with grooves, in general. a complex geometric figure. This is a specialized cord. Each comes with instructions on what exactly he cuts. For example, an asterisk. ideal for cutting lawn grass. Although it costs a little more, it cuts neatly, the tips of the grass cover look attractive and do not dry after cutting.

The better to mow the grass

Before installing the cutting attachment, consider what you will be cutting. If fresh grass, then the answer is unequivocal. choose a fishing line.

The line is a thin nylon thread. It is also called a cord, string or wire. The mowing head has a spool (reel) inside, on which this wire is wound. The spool is mounted on the shaft, the motor speed is transmitted to it through the gearbox. The ends of the line are exposed to the outside. When the spool rotates, they also rotate with tremendous speed and force. This is how the grass is mowed.

Cutting widths range from 40 cm to half a meter. The wider the wire mows, the faster you mow the lawn.

The line cuts well at any height. even the tallest that the lawnmower cannot handle. In general, there are many places where the lawn mower will not pass. narrow spaces, lawn edges, near curbs, flower beds, under benches. All these are places for brushcutters with a string tucked into it.

The wire is especially effective when mowing grass in the garden, since it only easily glides along the trunks of trees, and does not harm them.

It is convenient to mow grass for hay, but if the vegetation is tough and dense, use a knife.

How easy it is to wind the line around the trimmer head

The spool can be wound from 3 to 10 meters of wire. In the process of mowing, the nylon thread is erased, new ends must be exposed. There are several ways to accomplish this task:

  • Manual. To do this, you need to stop working, remove the spool cover and set the desired length. The process is simple, but it does not add to the speed of mowing.
  • Semi-automatic feeding. With this method, the new tips are exposed independently. To feed them, you just need to lightly hit the head on the ground. The anchoring mechanism is triggered and you can mow again. This option is a win-win. You do not need to stop the engine, stop mowing, and the feed is strictly regulated, therefore. economical.
  • Full automatic machine. A very convenient way. you simply reduce the speed and the ends of the cord are replaced with new ones. The system takes care of this on its own. The speed of work is greatly increased. But there is a small drawback. a large consumption of fishing line. You can’t control it.

When the thread runs out, you need to wind a new one. Refueling methods also differ. There are two types. manual and quick charger.

The most common is manual. Step-by-step actions:

  • Unscrew the mowing head. Open the lid. There are latches on the sides for this.
  • They remove the coil, as a rule, information is applied on it, what diameter, into which hole you need to push. An arrow is also drawn indicating which direction to wind.
  • Inside the coil, in the middle there is a side. On it is a groove for threading a loop.
  • We measure the length of the wire. Online users are advised to cut off 3-4 meters, no more. Since the winding is too tight, it is ineffective. Also remember that the thicker the line, the less you need to wind it.
  • The cut cord is folded in half. A loop is threaded, fixed by the bracket. The coil is held by the spring from itself. Hand-wound counterclockwise. You need to do it tightly and evenly. One thread lies at the bottom of the spool, the other at the top. The turns must not intersect.
  • The tips are inserted into the holes and exposed. Spin the coil. And the head in place. Fit the ends hitting the ground.

Sometimes the reel is designed to wind up two separate pieces. This can be seen when the coil is opened. It has a high projection in the middle, and there are two holes for fixing. The method is, in principle, the same, but the thread is divided into two parts, we fix the staples in the spool and wind.

The fast charging method is better, it differs in both speed and comfort. There is no need to disassemble the coil. It is enough to tuck the loop into a special hole and turn the mechanism. He himself will wind the line on the reel. All that remains is to adjust the tips.

What to put on the brush cutter instead of fishing line

Very often, trimmer owners and hedge trimmers want to improve the performance of these garden tools. This is due to the fact that when buying a gas cutter, few people think about the power, the radius of the grass bevel and other equally important characteristics.

Having purchased a tool, many find it difficult to mow small bushes and tall grass. Therefore, the question of what can be put on the trimmer instead of fishing line is more relevant than ever.

In principle, a slightly larger diameter line than the manufacturer’s recommended line can be fitted to the trimmer and hedge trimmer. You can also try to use a steel cable for these purposes, but here you need to be extremely careful and additionally secure.

Even the slightest bounce of a stone from the cable (or the piece of cable itself) towards the operator or other people can lead to unpleasant consequences, for example, injury. What else can be used instead of fishing line on the benzotrimmer?

What can be put instead of fishing line on a brush cutter and a gasoline trimmer

If it turns out that there is no special trimmer line at hand, then you can use the most common line. Usually they take a fishing line with a diameter of two mm, but you can try to put a fishing line and thicker.

The only thing you will have to face in this case. this is the difficulty of winding the line. The line is too soft, so everything here largely depends on the design of the reel. If it is necessary to wind the fishing line, then this must be done in a small piece.

It is much easier to install the line on the trimmer if its spool is not wound (it is enough to pass the desired piece of line or cable through the hole, and then click the spool).

Can I use a cable instead of a line on the trimmer

Of course you can. However, at the same time, it is worthwhile to understand all the insecurity of this venture and the ultra-fast failure of the gasoline trimmer transmission. After all, a steel cable is a hundred times stronger than a fishing line, even a special trimmer. It will not come off as often from grass, branches and stones, so it will last much longer.

At the same time, you need to understand that the line break during the trimmer operation is not just that, but from a strong load. As a result, the engine of the hedge trimmer does not stall and the dynamic shock of the hedge trimmer transmission is absorbed. In the case of a steel cable, the entire load will fall on the transmission, as a result of which it will quickly fail.

If you really want to try using a cable on a gas cutter, then at least you need to install it correctly. First of all, you cannot wind a long rope around the reel. Make it so long that it does not hit the trimmer guard when turning the reel.

Be sure to clamp the cable with washers in the middle and drop one drop of welding material onto its ends so that it does not bloom. As a result, the cable should not have protrusions, and welding at the ends will protect it from unraveling. However, even in this case, it is very unsafe to use the cable on the brushcutter or trimmer. It is much easier to use ready-made factory attachments.

How to put the knife on the trimmer

With the arrival of summer, many owners of personal plots are worried about how to put the knife on the trimmer. No less relevant are the questions of why and when it is advisable to replace the line on the hedge trimmer with a more durable cutting element. In our article we will try to disassemble all this and give useful recommendations to summer residents.

Why you need to put the knife on the trimmer

A trimmer with a knife attached to it is most convenient to use for more comfortable mowing of tall and coarse grass in the country. the line on the mower in such cases does not cope. Thin breaks down very quickly. Using a 2.3mm cord or homemade rods with ropes forces the vegetation to wrap around the reel. This increases the load on the engine.

  • By the type of material from which it is made;
  • By the shape of the cutting blades.

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

  • Type of brushcutters;
  • Mowing area.

For safety reasons, manufacturers do not recommend placing steel blades on electric trimmers. Almost all mains and battery powered hedge trimmers are equipped with plastic blades. Depending on the manufacturer, they can have a one-piece disc-shaped design, with several knives or in the form of a special mowing head with the ability to install removable plastic knives.

Straight rod for petrol trimmer and curved rod for electric.

It is not allowed to put a metal knife on an electric trimmer due to its design features.

  • The curved boom of the machine shortens the distance from the cutting head to the mower feet. In the event of a collision of the blades with a stone or other hard object, the scythe is thrown to the feet.
  • The high torque we mentioned above, in the event of a metal blade hitting a hard object, transfers a large load to the trimmer flex shaft and its motor. What makes them fail prematurely.
  • The scythe handle most often does not have a limiting bar that acts as a stop. Which does not exclude leg injuries.

It is these features that make it possible to use exclusively plastic knives on trimmers with electric motors. When hitting an obstacle, the blades are destroyed, thereby protecting the mower’s legs from possible injury.

The use of metal knives only on gasoline trimmers is also associated with design features.

  • Straight bar design increases leg clearance for total safety.
  • Comfortable U-shaped and J-shaped handles provide a secure grip. The D-shaped handles of the hedge trimmer are equipped with a stop that rests on the mower leg to prevent the head from getting close to the legs when the blade hits a hard obstacle.
  • The gasoline engine clutch allows for smooth acceleration to the optimum level. And when the blade hits a hard surface, it can partially absorb the impact.

Thus, petrol trimmers with a metal blade installed are best used in large areas. They will successfully cope not only with tall, coarse grass, weeds, burdock and nettles, but also with shrubs, as well as young trees.

The shape of the disc blades fed to the trimmer does not affect the quality of the work performed. Speed ​​does not depend on them either. Triangular, trapezoidal, rectangular shapes. all these are marketing gimmicks of manufacturers.

How to put the knife on the trimmer correctly

Putting a knife on a trimmer is not that difficult. The manufacturer completes his tool with a special pin that allows you to block the gearbox, and a wrench, with which the spool and fishing line are unscrewed. The most important thing. when replacing cutting elements, observe safety precautions and the sequence of assembly and disassembly.

The algorithm for setting the knife to the trimmer is as follows:

  • Remove the protective cover;
  • Let’s block the drive. To do this, you need to align the two holes. in the shaft hub and in the gearbox. Having connected them, insert a pin into the holes;
  • We unscrew the spool with fishing line or the fastening nut holding the boot (if the trimmer has not yet been used) clockwise from the hub;
  • Then position the cutter blade so that the grooves in the hub washer line up with the grooves in the hole in the cut-off wheel;
  • Install the boot;
  • Tighten the fastening nut (counterclockwise) while holding the locking pin;
  • We tighten with a tubular wrench;
  • Removing the protective cover.

As you can see, there is nothing difficult here. Now you can safely start mowing weeds on the site.

Brushcutter knife. Brushcutter knives. what for what.

Regardless of the principle of operation of brushcutters, electric or gasoline, none of them will work if there are no knives. After all, they are the main cutting part in the entire mechanism. For the correct selection of a trimmer knife, you need to have some knowledge in order to make the right choice. We are talking about the diameter, dimensions, as well as about its capabilities, which is very important in the future when performing work.

The brushcutter is based on a bar. At one end of it there is a motor in the upper part, and a head together with a coil on the lower part. And also the line is tucked into the trimmer. It plays the most important role in the mowing process. over, regardless of whether the plants are wet or dry. Also, the line copes with cutting trees, poles, fences, leveling surfaces, lawns, etc. Well, as for the sprouting shoots of shrubs, reeds, as well as young trees, in this case, it is the garden trimmer knife that will be ideal.

And so, in what cases is this or that used?

If you need to mow lawn grass, you can use a plastic mowing head (spool with line) or a metal mowing spider.

To mow grass, weeds or shrubs, use a 2, 3 or 4 bladed knife:

You can also use an eight-toothed knife to mow hay, grass or reeds. A forty-tooth or eighty-tooth knife is suitable for mowing overgrowth and reeds. A forty-tooth knife, which has a victorious soldering, is quite powerful, among those that come with a circular saw, it is convenient for them to cut trees and shrubs.

When choosing a trimmer knife, pay special attention to the diameter and thickness of the knife:

It should also be borne in mind that the diameter of the saw blade of the cutting knife is very important. Depending on how difficult the task will be for the brushcutter, the larger the diameter of the knife should be chosen. And in order not to harm beneficial plants growing near the mown plants, you should choose a smaller knife.

It is not recommended to save money when the garden trimmer knife becomes dull. If you sharpen it yourself, it can deform, as a result of which the centering of the knife will be disturbed. As a result, there is a risk of injury while using the tool. And 30 minutes after working with such a brushcutter, your hands will be very tired.

With the second component, the situation is a little more complicated. First, there are many technologies for joining metals and alloys. Secondly, any technology is a complex multistage organizational and technical process and compliance with production requirements at each stage is a separate complex task. To solve these problems, there is a system of standards united by the key concept “Product quality system management”.
At the same time, one must understand the following. to produce a quality product is always more expensive than a low-quality one. Let’s move from the presentation of the obvious facts to the practical plane. Currently, the Russian market has a large selection of Chinese-made knives of various price categories.

How to explain why Champion trimmer knives and brushcutters are more expensive than cheap Chinese manufacturers?

The coefficient of linear expansion of the applied steels is 2-3 times higher than the coefficient of linear expansion of the hard alloy. This circumstance requires that the heating and cooling of the carbide tool during brazing occurs uniformly (i.e. slowly) in order to ensure the preservation of the initial properties of the alloy and uniform heating of the surfaces, otherwise cracks will form on the carbide plates.

Materials and technology of cheap Chinese manufacturers. The knife blade is made of steel 40-45, blade thickness 1.15mm.1.20mm, HRC hardness 20-25 units. For the manufacture of knives with carbide cutting segments, tungsten-free cobalt alloys with m carbides of more than 50% (RMB120 / KG (≥50%)) with HRA hardness of 84 ± 1 unit are used. The segment size is 5.0mm / 1.5mm / 1.9mm.
The knives do not undergo heat treatment and additional grinding. The solder / additives do not contain silver. Carbide inserts are heated and cooled at an accelerated rate to reduce manufacturing costs. The results of the use of such materials and technologies may be low strength (chips, cracks), increased wear or shattering of the cutting knife segments.
The above differences are shown in the table.

We hope that the above reasoning and data will allow you to make the right decision when choosing knives for your trimmer.

When is the use of knives relevant?

When using brushcutters in summer cottages, the most popular attachment is the fishing line. It has a low price, is suitable for different trim heads, and is safe to use. The disadvantage of using a fishing line is that it is convenient only for mowing low growth. In other situations, the string will kick in immediately, regardless of whether a petrol or electric trimmer is used. In addition, vegetation is wound around the spindle, which creates significant resistance on the shaft and leads to its breakage. It can also provoke failure of the piston system in petrol cutters or engine burnout in electric trimmers.

Therefore, for mowing tall or hard vegetation, various attachments are used. So, for harvesting high and coarse grass, thin shoots of trees and shrubs, it is better to install and use a disc. This nozzle clogs much less often, which contributes to the greater wear resistance of the equipment.

On a note! Due to the fact that the engine of electric trimmers and battery models is less powerful than on petrol cutters, therefore the use of discs is more relevant for petrol mowers.

Disk selection criteria

It is necessary to choose a plastic or metal knife, taking into account the area of ​​the site that is planned to be processed, as well as the type of trimmer. electric or gasoline. The number of blades will depend on which growth needs to be removed with the tool. You can choose the desired disc shape, the number of blades and the material of manufacture using the instructions for use of the device. Usually it prescribes which cutters are recommended to be used for solving certain tasks.

Blades

The number of blades is important when solving diverse tasks. So, to grind the grass, two or three pieces are enough. To harvest hay, it is necessary that there are four to eight blades on the disc. To destroy small shoots of trees and shrubs, instead of blades on the disks, there should be a large number of small teeth.

Rules for replacing knives on the grass trimmer

If the trimmer disc is used regularly, it will need to be removed from time to time and sharpened or replaced with a new one. 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 for equipment from different manufacturers, be it Carver or Huter, but slight differences are possible. It is quite simple to change the knife on the trimmer if you follow the safety precautions and know the correct procedure, the description of which can be found in the user manual. The whole process of replacing step by step, as well as the method of self-sharpening knives, will be described in this material.

Material

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

Important! The straight bar ensures safe use of the trimmer when the disc is spinning and bumping into an obstacle. In this situation, it bounces back towards the person, so the curved structure can cause injury.

Plastic knives should be used on gooseneck trimmers for safety reasons. Their purpose is mowing soft grasses, dead wood. Whereas metal discs do an excellent job with tall, dense, hard shoots, bushes, as well as tree shoots.

Features of discs for brushcutters

Knife discs are available in plastic and metal, as well as in various shapes to perform diverse tasks.

  • Two-, three- and four-bladed knives with pronounced blades are used for mowing grass and tree growth. However, they are not suitable for making hay, as they grind the shoots, chopping them several times.
  • Massive four-blade discs are designed not only for clearing the ground from grass, but also for mowing hay. They prevent repeated cutting of the shoots, thus making them suitable for harvesting for the winter.
  • Discs with cutting edges around the perimeter are relevant for beveling reeds and reeds. These knives are very heavy. a necessary quality to cut through thick stems.
  • Professional saw blades for hedge trimmers and brushcutters for cutting small trees and bushes.

Plastic knives are used as an alternative to metal discs. They do not need to be firmly fixed in the head, but they rotate as a result of centrifugal force. The strength of plastic knives is high, so the service life is quite long.

On a note! The advantage of plastic discs is that, hitting an insurmountable obstacle, they bounce off, and repeated contact does not occur.

How to install a disc on a trimmer

Attaching the blade to the trimmer is very simple. For this, a complete wrench is used to disconnect the cutting attachment and a pin that locks the gearbox. The procedure is as follows.

  • First of all, the electric trimmer should be disconnected from the network, the petrol trimmer should be simply turned off. Disconnect the protective cover and move to the side.
  • Next, you need to align the holes on the gearbox and the shaft in order to insert a pin into them and block the drive.
  • If a spool with line was used, it must be unscrewed clockwise.
  • Then you need to find a nut to twist the knife.
  • The next step is to install the knives. Trimmer owners often wonder which side to put the disc on. This must be done so that the marking with numbers and letters is on top.
  • Then you need to put the boot on top, and above it. the fixing nut, which must be tightened tightly with a wrench.
  • The last step is to install the protective cover.

As you can see, the procedure is very simple and the same for many brands, whether it is Shtil or Husqvarna.

Insert the formed loop into the groove of the coil.

In line with the indicated direction on the spool, carefully lay the line.

Fix the short end in the groove on the side and the long end in the opposite.

Place the inner spool with wound tape into the spool body. Pull the line out of the locking grooves and put on the cover.

If necessary, trim the ends of the line to 10-15 centimeters.
