Patent ID: 7805844

Claim:
An electric bush cutter comprising: an electric motor that rotates a cutting edge through a centrifugal clutch; and operating means for adjusting rotational speed of the electric motor, wherein a range of operation of the operating means is divided into a plurality of regions including at least a starting region, a common-use region, and a first transition region, wherein the starting region includes a range of the rotational speed of the electric motor from a stopped state of the electric motor to fastening of the centrifugal clutch, wherein the common-use region corresponds to a range of the rotational speed of the electric motor suitable for a bush-cutting operation by the electric bush cutter, wherein the first transition region corresponds to a range of the rotational speed of the electric motor from the starting region to the common-use region, and wherein a rate of change of the rotational speed of the electric motor with respect to the operation of the operating means in the first transition region is greater than that in the starting region and that in the common-use region.
