ABSTRACT:
A tree is received on a guide and fed toward a rotating disc by a feed roller carried by an arm. The arm pivots to increase the force with which the feed roller engages the tree as the resistance to feeding the tree into the rotating disc increases. Wood chips are cut from the tree by a blade on the rotating disc which slopes upwardly across and generally in the direction of the feed of the tree. The wood chips pass through the disc and into pockets from which the chips are discharged through a duct. The wood chips are also propelled through the duct by an airstream produced by fan blades on the back of the disc. To separate debris from the wood chips as they are cut from the tree, the disc is received in a housing which extends above the disc and a discharge duct communicates with the housing above the upper face of the disc.
