ABSTRACT:
A hitch apparatus for detachably connecting a bucket to a power operated boom of a self propelled backhoe or excavator vehicle in which the hitch includes a body having a pair of upstanding side walls for hinge mounting onto the manipulative end of the boom. At the underside of the body secured in a relatively forward location of a bottom wall connecting the sidewalls is a hook member defining a transverse jaw channel in which to receive a transverse hingepin extending between spaced apart support lugs secured to the backside of the bucket. Rearwardly extending downward from the backside of the bottom wall is an elongated transverse sleeve adapted to be received intervening between the lugs of the bucket and containing a cyindrical rotatably displaceable bushing within the bore of the sleeve. The bushing is formed having an eccentric internal bore that by arcuate displacement of the bushing can be axially aligned with opposite apertures in the lugs. A support pin extending through the lugs and bushing secures the hitch apparatus attached to the bucket and can be withdrawn for subsequent detachment.
