Wood splitters configured and sized to be removably attach to an articulating arm on a mobile power machine such as backhoes, tractors, excavators or bulldozers. The articulating arm is attached to a powered wood splitter, which comprises a pusher comprising a wood holder area and an opposed splitter knife attached to the opposed thumb. The power of the mobile power machine is then activated to open the powered wood splitter to either capture/grab a piece of wood or to release it, or to close/squeeze, the pusher and splitter knife together, thereby splitting the wood held between them.
