ABSTRACT:
There is disclosed a quick coupling assembly for coupling a working implement to the front of the tractor. A front push-frame is adapted to be attached to the tractor chassis, with the front portion of the push-frame projecting forwardly of the tractor. Said front portion includes two upright legs, each provided with a horizontal stud and with a retractable locking pin below the stud. The assembly further includes a hook frame adapted to be attached to the back of a working implement, such as a plow or snowblower. The hook frame includes a pair of transversely-spaced hook plates, each having an upper downwardly-turned hook member and a hole below the hook member. To couple the hook frame, to the front push-frame, it is only necessary to drop the hook members on the studs and to allow the spring-biased locking pin to enter the holes of the hook plates. Hydraulic cylinders are provided to raise and lower the working implement through action on the push-frame. A system is also provided to adjust the vertical inclinations of the legs of the push-frame.
