Hinged plow attachment for wheeled and tracked vehicles

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. A plurality of slots are formed in one of the swivel plates and a corresponding plurality of swivel plate retention pins project through the slots and secured to the other of the swivel plates retains the swivel plates in assembly. A vertical blade pivot and plate secured to the forward end of the T-frame assembly and a pair of blade members having inner ends pivotally connected to the vertical pivot, respectively, are actuated by hydraulic actuators about the vertical blade pivot.
