Abstract: A log splitter for use in a high production environment utilizes a four-way, stepped knife blade at either end of a longitudinal stroke. A log is automatically placed and positioned between and at the center of the four-way knife blades by a hydraulically operated table. A self centering circular ram connected to a two-way hydraulic cylinder forces the log through either of the four-way knife blades depending upon which end of the stroke the ram was last positioned. The invention contemplates a conveyor input of logs and conveyor output of quartered logs.
