Abstract
A hand held battery powered vegetation trimmer, comprising a battery pack (,), which powers an electric motor (,) to generate a rotary output (,) and a cutting line (,) which is 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.
