As a result, the operating person of a Häbenerntefflaeehüie very quickly mild, eo that the work performance of the machine is considerably lower will.

The present invention is intended to remedy this situation.

Fig. 2 is a schematic representation of the hydraulic system the harvesting machine of FIG. 1.

The self-driving multi-row sugar beet harvesting machine of FIG. 1 has a hydrostatic power steering system with a hydraulic cylinder 2 which is mounted on the axle housing k of the steerable wheels 6. The cylinder housing 3 is connected to a stationary part of the axle housing, while the associated piston rod is connected to one

The hydraulic cylinder contains the pressure medium via a first one Control slide 18, which depends on the rotation of the steering wheel 20 is actuated in one direction or the other.

An additional control slide 22, which is operated electromagnetically, lies between the DructaaittelsaasaelbehMlter 24, the pump 26 and the hydraulic cylinder 2. Magnet coils 28 at the two ends of the slide piston 30 are in an electrical circuit with a Limit switch 32 and a further Orenzsohalter 34.

On an auxiliary frame 28 of the harvesting machine, behind one of the topping devices, are "!" 40 and in front of the associated lifting device, not shown, two buttons 36, which are pivotable with respect to the subframe 33 and on both sides of the row of beets to be harvested over the ground grind »but can move vertically upwards at any time.

It should also be noted that an electromagnetically actuated control slide 42 is interposed between the control slide 18 and the piston-cylinder arrangement 2. When it is energized, this control slide 42 interrupts the supply of pressure medium from the control slide 1 © to the piston * cylinder arrangement 2, which results from turning the steering wheel 20, so that the steerable wheels 6 are then steered by the steering wheel 20 without auxiliary power.
