Abstract
A hitch assembly provides removable connection of a plow assembly to a push beam assembly installed on a vehicle. The hitch assembly includes a draw latch assembly which engages the push beam assembly and pulls the plow assembly into position for pivotal attachment of the plow assembly to the vehicle. The draw latch assembly is activated by a power source, such as an hydraulic cylinder, and is further interconnected with a lift arm assembly such that further extension or activation of the hydraulic cylinder results in a raising or lowering of the plow blade. Also included is an easy connection and release mechanism for inserting and retracting pivot pins through corresponding brackets on the lift arm assembly and push beam assembly. A light tower assembly is removably attached to the push beam assembly such that when the plow is not in use, only the push beam assembly and its mounting brackets remain on the vehicle in a position below and rearward of a front bumper of the vehicle.
