Abstract
A brush/wood chipper having a small diameter pressing feed cylinder adjacent and parallel to an anvil which is generally perpendicular to the feed disc, the cylinder also being adjacent the chipping disc. This feed cylinder is in an infeed chute, and presses the branches, twigs or other wood against the anvil while the wood is fed to and chipped by knives on the disc. The radially oriented knives are each canted relative to the chordal anvil so that, preferably assisted by a canted feed cylinder, the wood is forced toward the center of the chipping disc. The infeed chute has a wall generally at the center of the disc. The chips are propelled to a flow arrester for discharge into bags or bypassed to a discharge chute extension, using a control valve at the flow arrester.
