A portable hydraulic log splitter assembly having separate power pack and log splitting modules is disclosed. The pump for the log splitter can be powered by either an electric or gas motor. The pump is operated in connection with a four position regenerative safety release valve that is biased toward neutral in the forward position so as to automatically disengage the cutting blade if the valve's handle is not manually held in an operational position by the user. The valve permits an increase in driving force applied to the cutting blade up to a predetermined limit to overcome log resistance. The valve has a further regenerative feature allowing for faster splitting strokes by the cutting blade. In order to reduce weight for portability purposes, the cutting blade (formed of tool steel) is mounted on a relatively lightweight aluminum base. Through holes in the cutting blade receive molten aluminum when the base is molded so as to be integrally mounted on and locked into the base. Weight of the splitting module is further reduced by use of tie rods to carry a log to be split.
