  • Patent number: 6408548
    Abstract: A pivotal snowplow is provided for mounting to the hitch on the rear end of a vehicle, such as a pickup truck. The snowplow includes a frame and a blade. The frame includes a tongue for mating receipt in the vehicle hitch socket. The frame also includes rearwardly extending arms and downwardly extending legs mountable to the snowplow blade. A hydraulic cylinder controls movement of the blade between raised and lowered positions. The legs of the frame are pivotally mounted to the arms of the frame such that the blade can be rotated about a vertical axis, thereby angling the blade relative to the direction of travel of the vehicle. The blade includes trip springs so that the blade can be tilted to pass over obstacles encountered during plowing. A pair of down pressure springs on the frame apply a downward force on the blade for improved snow removal.
