Abstract
A coupling assembly for releasably securing an implement to a work vehicle. The coupling system includes top wedges which are engaged in wedge-shaped sockets, and tapered lower hooks that apply a continuous force to a pin or cylindrical rod which operates to tightly engage the wedges in the wedge-shaped sockets, thereby preventing movement and resultant wear between the engaging portions of the coupling assembly and having the capability of handling heavy, high load inducing attachments as well as existing attachments.
