A hitch device between the implement/carriage (2) and towing vehicle, e.g. a tractor (4), including a first coupling part (6) adapted to be mounted in a lift system on the towing vehicle, e.g. a three-point suspension (8) of the tractor, and a second coupling part (10) adapted to be mounted on an implement/carriage (2), and which in additionis adapted to be connected with the first coupling part (6) with the purpose of coupling the implement/carriage (12) and the tractor (4) together, wherein the first coupling part (6) includes a projecting central journal (16) at a lower part (14) and laterally projecting bearing parts (18) at either side of the former, the journal (16) and bearing parts (18) adapted to interact with complementarily designed bearing parts (20, 22) of the second coupling part (10), and at an upper part (24) including rearwardly directed guide parts (26) that inwardly have bearings (28) for receiving complementarily shaped bearing parts (30) of the second coupling part (10), as the lower part (14) of the first coupling part (6) together with the complementary bearing parts (20, 22) of the second coupling part (10) constitute a mechanical draw coupling between the implement/carriage (2) and the tractor (4), whereas the upper part (24) of the first coupling part (6) together with the complementary bearing parts (30) of the second coupling part (10) constitute a hydraulic and/or electric connecting coupling between the implement/carriage (2) and the tractor. |
