Claim:
A method of improving a feed of woody material into a brush chipper with a feed table and a cutter head, said brush chipper comprising at least two feed rollers, the at least two feed rollers comprising respectively a first and a second axis of rotation and a plurality of cleats on each feed roller, each cleat having an upper end and a lower end, the method comprising: (a) orienting the axes of rotation of both feed rollers to be substantially vertical when the brush chipper is supported on a level surface; (b) orienting the plurality of cleats such that each of the plurality of cleats is not parallel to the axes of rotation of the feed rollers; (c) orienting an upper end of each respective cleat ahead, in an infeed direction of rotation of the feed rollers, of a lower end of each respective cleat; (d) rotating the two feed rollers in opposite directions; and (e) placing brush on the feed table between the feed rollers so that the cleats move the brush forwardly toward the cutter head and downwardly toward the feed table as the at least two feed rollers rotate in the infeed direction.
