A brush cutter (or trimmer) is a very popular device in the national economy. A type of small lawn mower. It differs in that it can be carried and worked with your hands, rather than, as usual, rolling a cart across the field. This is a fairly lightweight and convenient tool that copes well with large bushes and small grass. The main thing is to know which trimmer disc is better.

In our article, in 2 minutes we will tell you how to install a disc instead of a fishing line on a trimmer, how the attachments differ and when to use them correctly.

How to change the disc on a trimmer and what brush cutters they are used for

Trimmers differ in the way the engine operates. Electric and petrol options are available. The second ones have much more power than their competitors.

For miniature trimmers, plastic blades or lightweight metal elements are traditionally used. For mowers with higher power, you can even use a pobedit trimmer disc. But the restrictions affected not only the power of the devices.

The second principle is the mechanism: rigid or transmission. In the first, rotation is transmitted by a shaft, and in the second, by a steel cable. A flexible cable does not work with large disks, as it quickly becomes unusable.Therefore, for flexible transmission, use a spool of line instead of knives. You should find out the type of device before purchasing, so as not to end up with a quick breakdown.

Which trimmer knife is better to choose? Overview of possible options

Manufacturers produce several types of cutting elements for brush cutters. It all depends on the type of device. It is customary to distinguish between consumables:

• based on the material taken as a basis;
• shape and blades.

What material is best for a trimmer knife?

The purpose of the consumable is determined by the material: iron or plastic. The choice of one option or another is determined by several factors:

• area of ​​the production site;
• Which scythe do you use - gasoline or mains powered?

Important: metal cutters are never installed on network braids. The power of the device is not enough for full torque. Therefore, an alternative appeared - plastic. The design features of electric lawn mowers simply do not allow metal knives to work adequately:

• curved shaft;
• There are no palm rests - it is difficult to control a heavy tool;
• there is not enough rotation with a heavy knife.

Plastic blades are only used on appliances with flexible hoses. Plastic copes well with small grass, dry areas and burdocks. If you accidentally installed the wrong disk, see below: how to change the disk to a coil on a trimmer.

Metal based cutters. It is used for mowing thick, dense grass and small trees. The properties of the trimmer disc make it possible to install it when fighting bushes.

Technical and external characteristics indicating that you need an iron tip:

• a straight rod, which means the length of the device itself increases;
• convenient handles for controlling the scythe;
• adjusting the smooth rotation of the blade.

Tip: Gasoline units are well suited for mowing a large area with different types of grass and shrubs. You need to install a metal disk with sharp knives on them.

How many blades should there be?

The shape does not affect the efficiency of the blade as much as the total number of blades. For example, for future hay it is worth taking a cutter with 6-8 blades. With an amount of 2-4, the grass is cut into meat, and you will not mow any dead wood. For young trees, blades with many small teeth are excellent (look in stores for options with pobedit elements - also an excellent option).

Knives for lawn mowers are sharpened in different ways: on one or both sides. A dull or exhausted version increases fuel consumption and works inefficiently.

Important: try not to use blades in areas with stones or bricks. Just hitting the blade on a hard edge can break it. It’s worse if part of the pebble flies off in your direction. Be carefull!

How to change the trimmer attachment? The element should be selected based on dimensions, material and design. Also focus on the format of the job and the area you will be mowing. The instructions from the tool will partially help you. Manufacturers indicate which knife your equipment will use for which area. Well, we move on to how to properly place the knife on the trimmer.

How to install a disc instead of a fishing line or a new blade on a trimmer:

• Remove the plastic casing.
• We block the drive hole with a pin. It is necessary to simultaneously engage the gearbox and the shaft cup. If everything worked out, we move on.
• Unscrew the spool through the fastening nut (clockwise). If the trimmer is used for the first time, then the boot is unscrewed along with the structure. He's right there.
• We install the knife so that its hole coincides with the center of the spool and fits tightly into it.
• We attach the boot back.
• Without removing the stopper pin, tighten the nut (in the opposite direction).
• Tighten the nut with any wrench. The stronger the better.
• We install the protective casing.
