Abstract
A hitch adapter couples a semi-integral, PTO-driven implement to a quick coupler carried by a tractor three-point hitch. The hitch adapter includes a drawbar located significantly below the level of the connection of lower three-point hitch link with the quick coupler and a parking stand is integral with the bottom of the drawbar. Lowering of the three-point hitch from a normal working position results in the stand engaging the ground to prevent interference between the hitch and the drive shaft coupling the implement to the tractor PTO shaft. Once the stand engages the ground, the hitch adapter can be disconnected from the quick coupler hooks by releasing latches associated with the lower hooks and lowering the three-point hitch.
