ABSTRACT:
A self-contained, or externally actuated, hydraulic log splitter which includes a frame on which is slidably mounted an assembly of a specially designed push plate secured at one end to a reversible hydraulic cylinder and at the other to a splitting table carrying logs which is pushed against a straight blade to split the logs. A plurality of lines of discrete nubs are integrally a part of the push plate along a majority of its entire height and positioned substantially parallel to the straight blade and spaced away from the edge of the push plate. These nubs to provide specialized and improved gripping of log segments as they are split thereby minimizing the tendency of the split log segments to fly away from the splitter. An electric or gas engine driving an hydraulic pump or the hydraulic system of a tractor is connected to drive the reversible hydraulic cylinder.
