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 A support pin extending through the lugs and bushing secures the hitch apparatus attached to the bucket and can be withdrawn for subsequent detachment.

In combination, a vehicle having a manipulating boom, an implement to be manipulated thereby, and a hitch means for detachably coupling the implement to the boom comprising: first coupling means connected to one of the boom or the implement, and second coupling means connected to the other of the boom or the implement, one of the coupling means including bar means and a pair of eyelet means aligned along an axis spaced from and generally parallel to the bar means, the other of the coupling means including a hook means for engaging the bar means and a bushing rotatably journaled in a cylindrical bore and including a smaller bore located eccentrically to the cylindrical bore such that upon rotation of the bushing the smaller bore is moved relative to the hook means, the bushing being positionable generally between the eyelet means of said one coupling means when the hook means operatively engages the bar means and alignable with the eyelet means by rotation of the bushing means, and pin means insertable through the eyelet means and the bushing means when aligned to couple the implement to the boom, the pin means and bushing means including cooperatively interacting means for rotating the bushing means into alignment with the eyelet means as the implement is being coupled to the boom.
