Abstract
An apparatus is provided for delimbing tree limbs of a felled tree including housing structure constructed and arranged to be movable to a tree processing location. Support and feeding structure is constructed and arranged with respect to the housing structure to support a stem portion of the tree while a limb thereof is severed and to move the stem portion progressively through the housing structure. Blade structure is mounted on the housing structure and is constructed and arranged to move into engagement with a limb. Impact hammer structure is operatively coupled to the blade structure such that successive impacts generated by the impact hammer structure on the blade structure move the blade structure progressively thorough a limb. Actuating structure is operatively associated with the blade structure and is constructed and arranged to move the blade structure into engagement with a limb such that when the stem portion is supported by the support and feed structure and the blade structure is engaging the limb, the successive impacts generated by the impact hammer structure move the blade structure to sever the limb from the stem portion of the tree.
