"Two-axle agricultural tractor and / or harvesting machine, in particular Beet harvest maaehine "

The invention relates to a biaxial, elastic agricultural tractor and / or harvesting machine with tires, in particular beet harvester, the wheels of at least one axle being steerable and for the purpose of stabilizing the machine position at least one which is assigned to the chassis and can be lowered, engages in the ground and is driven by a disc coulter. formed and only serving as a stabilizing device (acting) stabilizer disc (slope disc) in laterally stable arrangement is provided.

To harvest crops like beets in rows od. The like. In hilly terrain also on a side sloping slope and / or when wet, the harvesting device in rows to keep, is known in various designs that have become known in practice (see, for example, the self-propelled beet harvester "S 21o" of the applicant) the rear wheel axle is followed by a disc coulter to prevent lateral drifting of the Reduce / prevent machine.

In order to avoid an unintentional trip - 2. Qt at the forgiving person - with lowered sesheibenseahen 1? To avoid this, it is preferred to provide the disk surface 17 together with the corresponding tool carrier unit (Paa. 11 bibs. 11 and 15) so that it can be lifted out, in particular to carry out the lifting device automatically with the lifting unit. On the one hand there is a hydraulic circuit for the Sdheibensech height adjustment and on the other hand a hydraulic circuit for the device carrying unit height adjustment (in particular lifting device height adjustment), whereby different pressures exist in both hydraulic circuits, either a mechanical shift lever coupling or an electrical / electro-mechanical coupling of the Corresponding control elements of both hydraulic circuits are available. ”Each disc coulter b2ui * disc coulter pair and the implement working in the ground (2nd B.
