ABSTRACT:
The log splitter of the present invention comprises a frame having a wedge fixed thereon. A slidable ram is mounted on the frame for longitudinal sliding movement toward and away from the wedge. A ram rod is connected to the ram and is further connected to a parallelogram toggle mechanism having one of its four corners fixed to the frame. As the toggle mechanism expands and contracts it causes the ram to move toward and away from the wedge. Hydraulic power means are connected to the toggle linkage for causing it to expand and contract.
