ABSTRACT:
A whole tree feeding and chipping assembly for longitudinally feeding whole trees with attached limbs and branches to a chipper wherein the chipper disc is arranged crosswisely at an acute angle to the longitudinal pathway of feed, and a feed works is provided for feeding the tree butt first to the chipper knives. The feed works includes a generally vertically disposed, fixed axis side feed roll on one side of the pathway, a generally vertically disposed swing side feed roll on the opposite side of the pathway; and a bottom feed roll disposed crosswisely to the pathway and defining the lower boundary of the pathway. A partly conical convergent chute minimizes frictional impedance and a plow is provided for moving debris from the vicinity of the feed works. The rolls are driven at coordinated speeds of rotation in a direction to feed the tree into the chipper mouth.
