PROBLEM TO BE SOLVED: To solve problems conventionally caused when a blade edge of a cutting blade comes into contact with hard foreign materials during work using a bush cutter, in which the blade edge of the bush cutter may bounce greatly to cause such an accident that the cutting blade comes into contact with people who are near.;SOLUTION: A second balance blade rotating in a direction opposite to a rotation of a cutting blade is newly incorporated on the upper part of the cutting blade so that a blade edge part of a bush cutter may not greatly bounce in recoil, unlike a conventional bush cutter which may, even if the blade edge of the bush cutter comes into contact with hard foreign materials. The above-mentioned rotations in mutually opposite directions cancel reaction forces of respective rotations to prevent the blade edge of the bush cutter from the dangerous bouncing back even if the cutting blade comes into contact with the hard foreign materials.;COPYRIGHT: (C)2015,JPO&INPIT
