ABSTRACT:
A support or hitch box supports a mounting bar in a selected vertical position. The mounting bar is received in a standard hitch receiver of any car, truck or other vehicle. A plow head is a light weight, strong, box like structure with oppositely directed mold boards so that the plow can operate in both forward and reverse directions. A linkage permits the mold board to be raised or lowered relative to the hitch box. The linkage includes upper and lower links to maintain the vertical orientation of the mold board. The plow head is mounted for pivoting in a horizontal plane. A pivot driver is user controlled to pivot the plow head and a lift driver is user operated to raise and lower the plow head. The plow head carries indicator lights. A spring, preloaded by the lift driver, applies a continuous down force to the plow head when it is the lower, plowing position.
