A horizontal boom is rotatably mounted on an upright support and serves as a track for a movable member supporting, by means of a flexible line, wood splitting mechanism. The wood splitting mechanism includes a cylinder and piston rod assembly having splitting elements thereon which are moved apart and together by operation of the piston rod for accomplishing the splitting function. The wood splitting mechanism is movable vertically by a winch drum thereon for splitting wood on the ground in the entire area of reach of the boom around the upright support. The cylinder and piston rod assembly have an interengagement which prevents rotation of the piston rod in the cylinder.
