ABSTRACT:
An implement is coupled to the forward ends of a pair of loader lift arms through the medium of an attachment assembly comprising a pair of implement carriers respectively vertically pivotally mounted to the pair of loader lift arms by a connector rod that extends through aligned holes provided in lower locations of the carriers, the connector rod being releasably fastened to each of the carriers so that the latter are pivoted in unison by hydraulic cylinders connected between the lift arms and upper locations of the carriers. The attachment assembly further includes a pair of downwardly opening hooks welded to upper locations of the back side of the implement and including arcuate portions respectively receiving cylindrical bars defining upper ends of the pair of carriers. Also fixed to the back side of the implement are a pair of rearwardly projecting, tapered connecting pins that are respectively received in holes provided in mounting plates forming lower forward portions of the carriers. The pins are located at outward locations which are visible to an operator so that the mounting of the implement to the carriers can be more easily effected. Quick clips are received through cross bores provided in the mounting pins so as to releasably maintain the connection between the implement and carriers.
