  • Wood splitter attachment
    Patent number: 4236556
    Abstract: A wood splitting attachment is provided for use with one of the stabilizer legs and attendant hydraulic ram of a conventional backhoe or the like. After separation of the ram from the stabilizer by removing the connecting pivot pin, a push plate is pivotally attached to the powered rod of the hydraulic ram and a support framework is pivotally attached to the stabilizer. The support framework includes side wings to cradle the wood and a wedge-shaped anvil is positioned on the after portion of the framework so that a piece of wood placed upon the framework is split by the wedge as the push plate urges the wood against the anvil. By disconnecting the push plate from the ram and the framework from the stabilizer, the ram and stabilizer can be reconnected to return the backhoe to customary use.
