摘要： A felled tree delimbing system which is skid mounted, having; a steel, horizontal chute with vertical cutting bars at one end where an overhead locking and cutting arm cooperates with the cutting bars. The operator engages the device by placing a bundle of cut trees horizontally on the chute, the tree's weight forcing down a trigger, causing the counter-weighted cutting arm to close over the trees forcing them into rectangular openings formed thereby. The bundle of trees is in the grasp of a logger's knuckle boom crane or similar piece of equipment at the lower portion of the tree trunks. The trees are then pulled along the chute through the edged rectangles, thus shearing off and removing limbs and branches from the upper part of the tree trunks. Upon removal of delimbed trunks from the chute, the unweighted trigger is released, allowing the cutting arm to return to an open position through action of pulleys and a counter weight.
