摘要： 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.

摘要： An operational lever for a bush cutter includes a handle housed in a handle case, a throttle lever pivotally mounted to the handle, and a lock lever pivotally mounted to the handle. The operational lever further includes a torsional coil spring which exerts a resilient force on the lock lever. The lock lever is pivoted from an initial position to a pivoted position by an operator's palm. The throttle lever is then pivoted to a half-pivoted position by operator's fingers. When the palm is moved a small distance away from the handle case with the throttle lever held in the half-pivoted position, the lock lever is pivoted back towards the initial position by a resilient force of the spring. This causes a curved surface of a side protrusion portion of the lock lever to engage or abut on a side of a protrusion portion of the throttle lever. This arrangement is advantageous in that even when the operator takes her or his fingers off the throttle lever, the throttle lever is locked by a friction force produced between the curved surface and the side.
