Abstract
An alignment fitting for implements such as buckets and hammers, which are to be removably attached to a bachhoe. The invention includes a pair of cylindrical bosses, which are affixed to opposing apertures in mounting flanges on the implement. A cylindrical bushing is rotatable inside each boss. A pin is placed through an eccentric bore in each bushing, and through the backhoe dipperstick. The eccentricity of the bushings allows the bushings to compensate for misalignment that may occur in the implement or the backhoe dipperstick. The invention may also be used with a hitch to provide greater tolerances when nonstandard size implements are attached.
