  • Patent number: 4262714
    Abstract: An attachment is described that is mountable to the rearward three point hitch members of a tractor and is operable in response to relative movement of the three point hitch members to split logs. The device includes a top hitch connector member that is releasably mountable to the single tractor top hitch member. A cross connector member is adapted to mount between the two tractor bottom hitch members. A splitting blade is mounted on one of the connector members and a log support surface is located on the remaining member. A guide mechanism is also provided for movably joining the two connector members for guiding relative movement of the wood support surface in a line toward and away from the cutting blade. Actuation of a conventional rocker shaft on the tractor to cause upward movement of the bottom hitch member will cause corresponding movement of the cross member toward the top connector member, thereby causing the wood support and the blade to move toward one another.
