  • Patent number: 4552374
    Abstract: A pulling hitch assembly, which includes a front beam which can be attached to a pulling unit, such as a tractor. An angle beam is pivotably attached to the front beam, and a pivoting device is provided which is associated with the front beam and the angle beam for effecting pivoting of the angle beam and the front beam relative to one another. Pivotably connected to the angle beam is a guide wheel assembly which includes a tire mounted on a wheel. Also provided is a fixed length cable which is connected to the front beam, is guided by the angle beam, and is connected to the guide wheel asssembly. The cable is disposed in such a way, and is of such a length, that it is adapted to pivot the guide wheel assembly relative to the angle beam, when the latter is pivoted relative to the front beam, in such a way that the tire of the guide wheel assembly is always disposed substantially perpendicular to the front beam.
