  • Patent number: 9957679
    Abstract: A snow plow system for an automobile features a frame connectable to a hitch receiver, a blade movable by an electrically powered actuator between a lowered snow-clearing position a raised transport position, a power unit placed within a trunk space of the automobile, a power connection line between the power unit and the actuator, and a wireless remote operable from a passenger cabin of the automobile. The power connection line traverses through a gasket sealed space between the trunk lid and trunk walls, thereby powering the device without any modification to the automobile. A flexible member connected between the actuator and the blade is operable to raise and lower the blade in a controlled manner under operation of the actuator, while allowing the blade to momentarily trip over ground level obstructions during use. A biasing mechanism forces the blade back into the snow-clearing position once the obstruction is cleared.
