Problems solved by technology

However, this is very dangerous and very inconvenient for the operator
[0008] Furthermore, the efficiency of the mowing operation is reduced by weeds becoming tangled or entangled in the area where the blade is attached to the brush cutter, preventing the blade from rotating
Also, since the drive motor is overloaded, its life is shortened and fuel is wasted

Abstract

The invention relates to a metal blade of a portable brush cutter, comprising a strip-shaped main body of which the middle part is equipped with a connecting hole, a knife blade is connected with the brush cutter via the connecting hole. Radial cutting blades are formed at the side part of the main body, so that the radial cutting blades are symmetrical with each other regarding to the connecting hole and along a diagonal line direction. Extending parts are extended from each part of the main body, edge cutting blades are formed at the corresponding outer ends of the extending parts and are extended aslant gradually along a direction reverse to a rotary direction. Tooth-shaped objects are extended from the side parts of the main body to be located at the opposite ends of the radial cutting blades, and are bent upwards or downwards relative to the main body, so that the cutting effect can be maximum by reducing rebound when operation is carried out in a hard boscage, and an accident can be prevented by avoiding the metal blade of the portable brush cutter being impacted with the ground or a barrier.

Description

technical field [0001] The present invention relates to rotary blades for brush cutters, and more particularly to a rotary blade capable of maximizing cutting effect by reducing kickback when acting in hard undergrowth, by avoiding contact with the ground or obstacles Prevent accidents by preventing collisions with objects and increase productivity by preventing cut weeds from tangling or becoming trapped where the blade attaches to the brush cutter. Background technique [0002] Generally, as shown in FIG. 1 , the blades 10 of the brush cutter are arranged as straight or cross-shaped blades. The blade 10 is connected to the brush cutter with a connection hole 20 in the central portion of the blade 10 so that it can be rotated by the rotational force from the brush cutter. [0003] The blade 10 also has a cutting edge 15 on its linear axis or cross axis portion, the direction of the cutting edge 15 is along the rotation direction of the blade 10, so that the cutting edge 15...
