An improved machine for disassembling all or a portion of wood pallets formed of paralleled stringers with deck boards nailed to the top and bottom edges of the stringers, the machine having a horizontal support arm onto which a stringer of a wood pallet is positioned, the deck boards of the pallet extending to either side of the support arm, a cylinder-piston supported above the support arm and having a piston rod extending therefrom for engaging a stringer positioned on the support arm and to clamp the stringer in position on the support arm, a carrier arm supported parallel to and spaced from the support arm, a hub slidable on the carrier arm, opposed cutter wheels rotatably supported to the hub, the periphery of the cover wheels being adjacent the opposed sides of the support arm, an a reciprocable cylinder-piston for moving the hub and therefore the cutter wheels to cut the nails holding the pallet deck boards to the stringer positioned on the support arm. The width of the support arm is controllably variable to permit adjustment for different width stringers.
