  • Patent number: 7975408
    Abstract: A snow plow includes a primary moldboard and auxiliary plow positioned behind the primary moldboard. The snow plow may be a one-way or reversible snow plow. In the later case, the primary moldboard and auxiliary plow are attached to a drive frame that is rotatable about a frame. The frame is secured to the front of a vehicle by a frame and bracket, and controlled by hydraulic mechanisms. The auxiliary plow is operated independently of the moldboard by a pair of hydraulic cylinders and includes tines or a resilient blade for clearing snow and ice that is not taken up by the primary moldboard. The device also includes a mechanism whereby the scraping edge of the secondary plow follows the same path as the scraping edge of moldboard by sliding movement of the secondary plow relative to the drive frame, and the blade of the auxiliary plow may be formed by tines or a resilient blade.
