In the angled in an advantageous manner, the steering column is laterally horizontal position, the steering wheel is to be pivotably mounted outside of the driver's seat and can be operated by one of the tractor. One of the inwardly bent arm on which the like arrangement is only useful if the steering wheel is repositioned. The swiveling position vehicle travels at low speed, while the steering column is per se from the French rend, during which the driver runs alongside the vehicle.
