ABSTRACT:
A flexible shaft is connected directly to the crank shaft of a snowmobile engine by a coupler. The flexible shaft drives a reduction gear which is enclosed in a hand-held housing. The reduction gear rotates a drive shaft at a substantially reduced speed and the drive shaft connects to the ice auger bit through a coupler which allows disengagement of the bit when no downward pressure is applied to the housing.
