The trimmer is an excellent and very useful tool that today has almost completely replaced hand braids. With it, you can not only trim the overgrown lawn, but even prepare hay for the winter.
Naturally, with a fairly tough operating mode, special attention should be paid to the selection of the right supplies. In many cases, the trimmer knife is the best choice.
Why a knife?
Yes, fishing line is more common and costs less. But when mowing tall grass, it often happens that it is wound on a spindle, greatly complicating the process and accelerating tool wear. In many respects, the frequency of this phenomenon depends on the correct design of the head, but this will still not be possible to avoid. That is why the knife for the trimmer is much more convenient and preferable.
Some characteristics
Today, the industry produces dozens of types of these consumables, and they can be made not only of metal, but also of plastic. It is not necessary to consider that the latter are disposable, as they can become a convenient and durable replacement of fishing line in those areas where high strength is not required.
When and how to apply
If you use a trimmer with a flexible bar, then only plastic knives or fishing lines are allowed. This requirement is due
to safety regulations. Note that the plastic knife for the trimmer is often applied to its products by the manufacturer.
But a much better disk metal head with a variable number of blades. She does not care even overgrown with old weeds and burdocks, which can tear more than one hundred meters of fishing line. Yes, and plastic knives in this case are bad helpers.
If you often work on large spaces that have small bushes or just stiff grass stems, you should only use metal tips. Note that collisions with stones or some kind of metal trash (from agricultural machinery) also lead to their failure in most cases.
What form to choose?
Do not believe the sellers who are trying to sell foam knife at the mouth with some exotic shape, equipped with a dozen blades. Experienced gardeners say that the shape and size of the blades practically do not affect anything. Quantity is only important if you are harvesting hay. If there are four or more blades, then grass cutting is obtained.
It is believed that for haymaking, the Patriot trimmer knife is equipped with several small teeth (it is almost round). If you want to deal with a site that is completely overgrown with weeds, and the power of your tool is not too large, it is better to buy perforated knives made of hardened steel. They are very light, but they cut just fine.
By the way, a good knife for a Stihl trimmer with similar characteristics will allow not only to remove dry and hard grass from the site, but also to deal with small trees that managed to be wiped out in a couple of years. Note that for such outstanding results you need to buy supplies only in specialized stores, since a knife made of poor Chinese steel can lead to very unpleasant consequences.
