Title: Self-aligning delimbing apparatus

Abstract: An improved self-aligning tree delimbing apparatus for use in conjunction with a knuckle boom loader having an inner frame member pivotally mounted and concentrically received within an outer frame member, which is rigidly attached to a base member. Pivotally mounted within the inner frame member is a tree delimbing cutter head assembly having opposing pairs of tree guide arms and tree delimbing arms pivotally mounted thereon, thereby allowing for simultaneous multi-dimensional pivotal motion of the cutter head assembly within the frame members. Such motion allows the cutter head assembly to easily align with the longitudinal axis of the trees being delimbed, thereby increasing the efficiency of the apparatus while reducing the binding stresses and necessary force applied by the knuckle boom loader.
