  • Snow plow and mount assembly
    Patent number: 11555282
    Abstract: A snow plow and mount frame assembly permits an operator to attach and detach a snow plow to and from a mount frame secured to a vehicle, without the operator exiting a cab of the vehicle. The assembly comprises a mount frame, a snow plow frame, a plow blade, a first actuator for pivoting the A-frame relative to the lift frame, a latch mechanism, and a second actuator to either latch or unlatch the latch mechanism. When the vehicle is driven toward the snow plow the snow plow frame mates with the mount frame and an electrical connection is made between the vehicle electrical system and at least the first actuator without manual manipulation. The second actuator is energized to either latch the latch mechanism thereby securing the snow plow frame to the mount frame or unlatch the latch mechanism thereby freeing the snow plow frame from the mount frame.
