Abstract

A tree feller assembly for use with a tree harvesting apparatus including a support structure defining a common pivot axis with a pair of shear arm means carrying cutter blade means disposed for pivotal movement about the common pivot axis. First power actuator means connects the shear arm means together and is disposed below and forwardly of the common pivot axis for moving the cutter blade means toward and away from one another upon actuation thereof. A pair of clamp members is pivotally mounted on the support structure above the shear arm means with a second power actuator means connecting the clamp members together. The clamp members are disposed forwardly of and generally parallel to the first power actuator means for moving the clamp members toward and away from one another. A wear plate means is mounted on the support structure and is disposed between the shear arm means to provide a guide for and self-aligning action on the cutter blade means upon actuation of the first power actuator means.
