摘要： A mechanism for clearing paths through a crop bed for the wheels of a tractor includes a pair of power driven vertically, parallelly disposed rotatable cylinders positioned forwardly of a wheel to be moved through a crop bed. The cylinders are rotated in opposite directions so as to engage and thereby displace a crop to either side of a path of a wheel. The speed of rotation of the cylinders is typically in excess of the speed of the tractor. A mounting for the cylinders is cantilevered forwardly of a wheel and includes a mounting for the cylinders which allows independent, limited rotation about an axis transverse to the motion of the tractor so as to permit the lower ends of the cylinders to pass over obstacles that may be present in the crop bed.
