Abstract
The invention relates to a device for stabilizing the two lower steering arms (1) of a tractor. The lower steering arms (1) can be actuated by a hydraulic power lift (9). Each lower steering arm (1) is associated with a side strut (6) which includes a single-acting hydraulic cylinder (7) to stabilize and secure the lower steering arm (1). A pre-selection valve (12) and a control valve (13) enable the hydraulic cylinders to be connected to the power lift (9) either via a line or loaded separately by a second pressure source (P2). Thus, independently of the actuation of the power lift (9), the two lower steering arms can be centrally centered by the hydraulic cylinders (7).
