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.

Snow plow and mount assembly

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.

An hydraulic and electrical control system are provided for an accessory unit such as a vehicle mounted V-plow blade snowplow.

The magnetic interface between the housing and armature of a poppet type electromagnetically actuated fluid control valve creates a magnetic flux path through opposing axially and radially facing surfaces of the housing and armature to reduce the pull-in voltage of the valve at large axial gaps between the armature and housing.
