ABSTRACT:
A coupling device is disclosed for attaching an implement such as a backhoe to a tractor or other prime mover. The coupling device includes a pair of implement support assemblies connected together by a transverse cross bar for mounting an implement support frame. Each implement support assembly includes a frame bracket or weldment having an attachment pin receiving recess or hook at its lower end for holding a transverse attachment pin which is secured to the lower implement support frame. Yoke assemblies are pivotally attached between the implement support frame and each implement support assembly for the purpose of tightly securing the implement attachment pins against the frame bracket recesses, thereby eliminating any tolerance movement at the attachment points between the implement and prime mover.
