How to change the disc on the trimmer and for which lawn mowers they are used

Trimmers differ in the way the engine works. There are electric and petrol options. The second - have a capacity much more than their competitors.

For miniature trimmers, plastic knives or light metal elements are traditionally used. For more powerful mowers, even a victorious trimmer disc can be used. But the restrictions affected not only the power of devices.

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

What is the best trimmer knife? Overview of options

Manufacturers produce several varieties of cutting elements for lawn mowers at once. It all depends on the type of device. It is customary to distinguish between consumables:

• according to the material taken as a basis;
• shape and blades.

What is the best trimmer blade material?

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

• area of ​​the production site;
• which scythe you use - on gasoline or from the network.

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

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

Plastic blades are only used on instruments with flexible hoses. The plastic handles fine grass, dry patches and burdock very well. If you accidentally installed the wrong disc, see below: how to change a disc to a coil on a trimmer.

Mills based on metal. It is used for mowing thick, dense grass, small trees. The properties of the disc for the trimmer allow you to install it when dealing with bushes.

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

• straight rod, respectively - the length of the device itself increases;
• comfortable handles for controlling the scythe;
• setting for smooth blade rotation.

Tip: for mowing a large area with different types of grass and shrubs, gasoline units are well suited. On them you need to install a metal disk with sharp knives.

How many blades should be

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

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

Important: try not to work with blades on areas with stones, bricks. Just hitting the blade on a hard edge can break it. Worse, if part of the pebble flies off in your direction. Be carefull!
