ABSTRACT:
A snow plow implement for quick connection to a vehicle. The moldboard of the implement is mounted for yieldable but limited pivotal movement on the forward end of a rigid push frame which includes a pair of rearwardly extending arms. Pivotal jaws and associated fork plates are mounted on the rearward end of each arm. A frame assembly mounted on the front end of the vehicle includes a pair of axially aligned hitch pins. As the vehicle is driven toward the implement, the hitch pins engagingly pivot the jaws to closed positions wherein they cooperate with the associated fork plates to firmly retain the hitch pins and thereby couple the implement to the vehicle. Spring loaded locking pins act automatically to lock the jaws in their closed positions. The coupled implement is raised and lowered about the pivot axis of the hitch pins by a power cylinder which is folded up within a protective arm member when not in use.
