Abstract: A hand-held control device for a V-blade plow in which left and right plow blade wings are pivotally mounted on a vertical pivot on a vehicle mounting frame and actuated about the vertical pivot by electric switch-controlled hydraulic actuators, there being an electric switch to control the extension of a hydraulic actuator, respectively, and an electrical switch for controlling retraction of the hydraulic actuator, respectively. Each electrical switch has an associated thumb actuator, the thumb actuators being in an array so that an operator's thumb or finger can actuate two thumb actuators simultaneously while gripping the hand-held control device with the same hand. The plow includes a third hydraulic actuator for raising and lowering the frame relative to ground and an electric switch pair for controlling extension and retraction, respectively, of the third hydraulic actuator.

Abstract: The present invention provides a powered attachment system for coupling a plow or other implement to a vehicle. A plow lift cylinder extends to push the coupler up into position, aligning spring-loaded upper pins. Further, the spring-loaded pins automatically engage when the coupler holes are aligned with those of the push beam.

Abstract: A plow having a frame attached to a vehicle and a pair of hinged plow blades pivotally mounted on the frame, a first single acting hydraulic actuator extending between the frame and a first one of the plow blades, a second single acting hydraulic actuator extending between the frame and a second of the plow blades, a first tension spring extending between the first one of the plow blades and the frame, a second extension spring extending between the second plow blade and the frame. Each of the single acting cylinders includes a piston on a cylinder, characterized by each single acting hydraulic actuator includes hydraulic valve elements for locking the blades in position to prevent loss of material mass behind the blades when the plow is being used to back blade. In one embodiment, the single acting hydraulic actuators include a counterbalance valve located in the position of the cylinder to provide hydraulic locking and overload protection.

Abstract: A V-blade plow having a pair of adjustable plow blades. Each plow blade has an inner end pivoted on a central pivot assembly. A plowed material catcher member is mounted below the central pivot assembly to prevent a trail of snow from passing through any space between the inner ends of the blades at any position of blade adjustment. The plowed material catcher member includes an arcuate ramp portion which projects forwardly of the central pivot assembly and directs snow to the blades respectively. The catcher member is made from a material selected from rubber, plastic or metal.

Abstract: A plow blade mounting system for mounting an adjustable V-plow blade on any wheeled or tracked vehicle having a vertical lift mechanism including arms extending forwardly of the vehicle. A rear mounting plate assembly has a first swivel plate adapted for attachment to the vertical lift mechanism and a pivot member secured to the first swivel plate. A second swivel plate is pivotally mounted on a pivot member, and a T-frame assembly is securely mounted on the second swivel plate and has a forwardly projecting end and a triangularly shaped plate member secured to the second swivel plate and the T-frame. A hydraulic actuator extends between the first and second swivel plates for effecting relative rotating movement of the first swivel plate relative to the second swivel plate about the pivot member.

Abstract: A quick hitch-unhitch attachment for mounting a snow working implement on a vehicle, comprising a vehicle mount attachment (VMA) frame secured to the vehicle, has a pair of spaced sockets which are positioned below and behind the vehicle bumper when mounted on the vehicle. A first pair of reaction bearing surfaces are aligned with and to the rear of the spaced sockets and a transverse latch bar means extends transversely of the sockets. An intermediate support frame has a rearward end with a pair of latching arms extending in a rearward direction and in general alignment with the sockets, respectively. Each latching arm has a further reaction bearing surface for bearing against respective ones of the first pair of reaction bearing surfaces. A support frame has a forward end attached to the snow working implement and a rearward end pivotally connected to the intermediate frame for rotation about a horizontal axis.
