Best Selling Grass Cutter Heads (Corded Heads)

Best-selling grass trimmer heads. This clearly means that these heads are well known to everyone. Their use is mainly recommended as a supplement to the lawnmower around trees, posts, outdoor flowerpots. This is exact whether the ground is level or sloping.

  • The cutting line allows finishing work to be carried out around obstacles and if the cutting line is too long, the flap knife automatically readjusts it. Simple to operate, the first line trims the grass once, then the second line cuts it back, generating a “mulching” effect that eliminates the need to collect the mown grass.
  • You may be wondering what the best brush cutter line is? Don’t worry, we’ve got you covered in this article.
  • Again, the best cutting line for your brush cutter/lawn trimmer or grass cutter depends on the power (displacement) of your machine.
  1. If you have less than 1 kW or less than 20 CC, you need a cutting line with a diameter of 1.2 to 1.6 mm, which is usually the case for trimmers.
  2. For a power of 1 to 2 kW or from 20 CC to 25 CC, you require a cutting wire of 1.6 mm to 2.4 mm in diameter.
  3. For power above 2 kW or 25 DC to 35 DC, you will need 2.4 mm to 2.7 mm diameter cutting wire.
  4. From 35 CC to 40 CC, 2.7 mm to 3.5 mm diameter cutting wire is required.
  5. And finally, for a displacement of 40 CC to 50 CC and more, 3.5 mm to 4.5 mm diameter cutting wire is required.

Best brush cutter head for thicker grass (PolyCut)

For thicker grass, you use the PolyCut mower head.

The other special feature of the PolyCut mowing head is that in the event of an accidental collision with an obstacle, the knives fold back into the head to limit the risk of breakage in order to maintain the tool’s full performance. The mobile knife is extremely easy to maintain. When its cutting edge is dull, it can be turned over to use its second cutting edge.
