Abstract
A snow plow and mount frame assembly permits an operator to attach a snow plow to a mount frame secured to a vehicle, without the operator exiting a cab of the vehicle. The assembly comprises first and second connectors on the mount frame and the snow plow, respectively, that connect during mating of the mount frame with the snow plow as the vehicle is driven toward the snow plow, to provide power to the snow plow from an electrical system of the vehicle, a first actuator powered by the vehicle electrical system to pivot a lift frame of the snow plow upwardly relative to an A-frame of the snow plow to align holes in the lift frame with holes in the mount frame, a second actuator powered by the vehicle electrical system to extend latch pins through the lift frame and mount frame holes to a latched position, a first sensor powered by the vehicle electrical system to determine that the lift frame and mount frame holes are aligned, a second sensor powered by the vehicle electrical system to determine that the second actuator is fully extended, and a controller that receives signals from the first and second sensors and sends signals to the first and second actuators in response to the signals received from the first and second sensors.
