ABSTRACT:
A lightweight snow plow apparatus for attachment to the front of a vehicle comprises an aluminum moldboard swivelly mounted in an easily removable manner on the ends of tubular telescopic side beams of an aluminum H-frame, the other ends of the side beams being removably pivoted to a pivot tube mounted on the frame of the vehicle. The side beams are telescopically moved to angle the moldboard by a rack and pinion mechanism housed in the side beams and in the cross beam of the H-frame and which is driven by an electric motor, connected to the electrical system of the vehicle, through a gear box that includes a slip clutch to prevent overloading. The H-frame and moldboard are lifted off the ground and lowered to the ground by an electric motor driven linear actuator, connected to the electrical system of the vehicle, which is pivoted to the cross beam of the H-frame and mounted on a bracket which is removably supported on the front bumper support of the vehicle.
