<p>A hitch adapter (50) couples a semi-integral, PTO-driven implement (26) to a quick coupler (18) carried by a tractor three-point hitch (12). The hitch adapter (50) includes a drawbar (86) located significantly below the level of the connection of the lower three-point hitch links (16) with the quick coupler (18) and a parking stand (90) is integral with the bottom of the drawbar (86). Lowering of the three-point hitch (12) from a normal working position results in the stand (98) engaging the ground to prevent interference between the hitch (12) and quick coupler (18) and the drive shaft (46) coupling the implement (26) to the tractor PTO shaft (24). Once the stand (90) engages the ground, the hitch adapter (50) can be disconnected from the quick coupler hooks (80) by releasing latches (82) associated with the lower hooks (80) and lowering the three-point hitch (12).</p> |
