ABSTRACT:
A rock raking apparatus which is adapted to be attached to a self-propelled vehicle and includes a rock raking unit with a toothed rotor and a rock collector bucket pivotably connected to the raking unit. The rotor is driven to propel rocks into the bucket. The raking unit includes a power-rotated brush positioned to deflect the propelled rocks into the rear of the bucket, to clean the surface of the rotor to prevent carryover and to prevent the formation of rock barricades at the entrance of the bucket to assure that the bucket is filled. The rotor is based on a cylindrical drum having a pattern of symmetrical radially extending teeth affixed to the peripheral surface thereof, with the pattern also being symmetrical so that the drum is reversible end for end when the leading edges of the teeth are worn. Double pivot mounts allow limited floating of the raking unit with respect to the bucket to accommodate uneven ground.
