ABSTRACT:
A hand held battery powered vegetation trimmer includes a battery pack that powers an electric motor to generate a rotary output and a cutting line adapted to be rotatably driven by a line support structure. By introducing a reduction gear stage between the motor output and the line support structure, the speed at which the line is rotated is reduced which substantially reduces the power consumption of the trimmer without reducing the cutting performance of the line.
