A motor driven agitator comprises a frame and a plurality of shafts rotatably coupled within the frame. The plurality of shafts are operationally coupled to the motor. The axes of the plurality of shafts are substantially parallel when coupled within the frame. The agitator further comprises a plurality of scalping agitators coupled to each shaft of the plurality of shafts. The agitator may further comprise a plurality of screening spaces each having a predetermined spacing. Material placed on a top side of the agitator is agitated by the plurality of scalping agitators while the plurality of shafts rotate, screening small material through the plurality of screening spaces while maintaining the larger material on the top side of the agitator. The agitator may be removably coupled to a mechanical bucket.
