  • Patent number: 5950336
    Abstract: A removable V-plow system for a vehicle includes both a push bar and an idler bar that are positioned and sized so that the vertical orientation of the plow blades with respect to the vehicle chassis remains fixed as the plow blades are raised and lowered. Raising and lowering of the plow blades is accomplished automatically by an operator-controlled actuator mechanism accessible to the driver of the vehicle that provides power to an electric actuator to raise and lower the plow. By maintaining a fixed orientation for the plow blades with respect to the vehicle chassis, down pressure can be evenly distributed along the bottom cutting edge of the V-plow onto the ground surface even when the plow is in a forward V, reverse V, or diagonal configuration. The plow includes a simplified trip mechanism, and a mounting system that facilitates convenient mounting and dismounting of the plow from the vehicle.
