Claim 1
Independent Claim 208 words
In a hydraulic log splitter attachment, the combination of a frame with an upper surface comprised of a pair of opposing parallel, spaced apart metal channels with web members separated by a row of inclined spaced apart spacers welded to said web members, one end of said frame supported upon legs having wheels, and opposite end of said frame having a bolt mounting opening therethrough for attachment to a tractor or other hydraulic power source, a hydraulic cylinder mounted axially upon said opposite end of said frame, a ram and a piston rod connected to said hydraulic cylinder, said cylinder having hydraulic lines extending therefrom for connection to said power source, the first said end of said frame adjustably supporting a splitter block having downward inclined feet for placement selectively between said spacers, and said splitter block being wedge-shaped with a blade edge thereof facing toward said ram, said ram slidably engaging said frame, so to force a cord wood log placed between said ram and said splitter block against said splitter block blade edge so to split said log, said block having a lower surface engaging said upper surface for support, including means on said block to cut the log at right angles to said blade edge.
