ABSTRACT:
An improved feed roller assembly wherein the feed roller provides a force perpendicular to the feed direction of the brush material. In a first embodiment, cleats that are not parallel to an axis of rotation of the feed roller are affixed to a periphery of the feed roller. When the feed roller is oriented with its axis of rotation in a substantially vertical position, each cleat is arranged with its upper end ahead of its lower end, in a direction of rotation. This configuration provides a downward force on the logs or brush being fed into the chipper, thereby reducing the occurrence of bucking. In an additional embodiment, the axes of rotation of the feed rollers lean toward the outfeed end of the brush chipper.
