ABSTRACT:
A pavement planing device including a rotating wheel on which a plurality of cutter holders are pivotally mounted. Restraining stop members mounted on the wheel limit outward swinging of the cutter holders as the wheel is rotated. Retraction stop members mounted on the wheel are engaged by the cutter holder members as they swing backwardly following impact with the surface of the pavement. The cutter holder members can rebound from the retraction stop members to cause multiple tool impacts by each cutter holder during a single pass on the surface being cut.
