ABSTRACT:
A bush cutting machine including has an operation rod, a cutter blade mounted to the front end of the operation rod for undergoing rotation, and a prime mover mounted to the rear end of the operation rod for rotationally driving the cutter blade. A throttle lever is pivotally mounted with respect to the operation rod for controlling an opening degree of a throttle valve of the prime mover to adjust a rotational speed of the cutter blade. A brake unit stops rotation of the cutter blade. A link mechanism is disposed in close proximity to the prime mover and is actuated by operation of the throttle lever to adjust the degree of opening of the throttle valve of the prime mover and to release the brake unit from a braking condition.
