Abstract of the Disclosure The present cutter head assembly includes guide lever members engageable with the trunk of the tree so that the curved cutting and limb stripping blades are maintained parallel with the longitudinal axis of the tree as the tree is pulled through the cutter head assembly by the grapple of a knuckle boom loader or the like. The cutter head assembly includes a rectangular support frame with a pair of curved cutting and limb stripping blades pivotally supported for movement toward and away from each other and adjacent one end of the rectangular support frame. The stripping blades define a tree encircling cutting opening therebetween for longitudinal movement of the tree in one direction through the cutting opening. A pair of curved guide levers is pivotally supported for movement toward and away from each other and adjacent the other end of the rectangular support frame. The rectangular support frame is supported for a limited amount of pivotal move- ment in both vertical and horizontal planes so that the support frame and the curved stripping blades and guide levers are automatically maintained in alignment with the tree trunk so that the axial alignment of the cutter head is not dependent upon the skill of the operator of the knuckle boom loader.
