This is a new style fully adjustable hitch that we have designed and manufactured. The hitch is built out of 6061 CNC machined aluminum and CNC machined steel. All steel parts have been zinc plated and all of the aluminum parts have a machined finish. The screws that can be seen are all stainless steel. This is direct bolt on replacement for all factory Cub Cadet gear drive transmission rear covers. There is not rear fill plug on this as most pulling transmissions can be filled from the top shifter cover.
