ABSTRACT:
A cutter head assembly for delimbing trees includes two pairs of opposing curved limb-stripping levers including curved cutting blades. The limb-stripping levers of each pair are pivotably movable toward and away from each other for engaging and encircling the trunk of a tree. One pair of levers is positioned and configured for engaging and removing limbs from opposite side and lower portions of a tree trunk being drawn longitudinally through the cutter head assembly. The other pair of levers is positioned and configured for engaging and removing limbs from opposite side and upper portions of a tree trunk. The limb-stripping levers include angled deflecting members attached to the cutting blades for deflecting cut pieces of a tree outwardly away from the cutting blades.
