ABSTRACT:
A woodsplitting machine has a plurality of wedges of various sizes and configurations radially attached to a rotational member mounted on the frame behind the log cradle such that an operator can quickly and easily rotate the appropriate wedge into position depending on the diameter of the log in the cradle to be split. The rotational member can be hydraulically actuated such that the wedges can be rotated around the longitudinal axis of the machine with little effort for the operator. An alternate embodiment provides that the rotational member be manually rotated such that the wedges can be rotated around the longitudinal axis of the machine by the hand of the operator.
