While controlling the rotation of the blade, swing the operation tube and perform the desired mowing work.

  • the nylon cord cutting blade 92 has moderate flexibility even when the rotary blade X comes into contact with an object that is harder than weeds, such as stones, concrete pieces, or guardrail columns. Therefore, it does not sag flexibly and generate a large impact force. Therefore, it can be avoided that the object is crushed and the fragments are scattered around and the rotary blade X itself is damaged.
  • Nylon cord cutting blade 92 has a higher peripheral speed and a higher cutting ability toward the tip in its rotating state, but the portion near the base end is closer to the tip where the peripheral speed is slower. Cutting ability is inferior to the part.

It becomes. The portion near the base end of the nylon cord cutting blade 92 has insufficient cutting ability, so it is difficult to cut the weed 93 instantaneously. On the other hand, even in this case, the portion near the tip of the nylon cord cutting blade 92 is relatively fast.
  • the rotary motion is continued in the circumferential direction due to its inertia.
  • the Nylon cord cutting blade 92 may be bent halfway at the portion where the weed 93 collides, and the portion near the tip may get tangled with the weed 93.
  • rotation of the rotary blade X is impeded by the weeds through the nylon cord cutting blade 92. Since portable power brush cutters are required to be lightly carried by workers, the power source, such as the engine, is also small and light and has a relatively low output. Therefore, the rotation of the rotary blade X may be stopped due to the rotation inhibition by the weed 93 as described above.
