A side strut ( ) for a lower steering arm of a tractor has a single-action hydraulic cylinder and a setting unit with a hollow cylinder ( ) and an adjustable setting element . The setting element ( ) includes a threaded bore ( ) which receives a threaded rod ( ). The hydraulic cylinder has a first attaching element ( ) to connect to a tractor. The threaded rod ( ) has a second attaching element ( ) to connect a lower steering arm. In the fully moved-out position of the hydraulic cylinder, the setting element ( ) is rotatable by an actuating lever ( ). Thus, the threaded rod ( ) moves in and out. To prevent any rotation, a first holding element ( ) is provided. The actuating lever ( ) engages the holding element in a rest position. A second holding element ( ) is provided to ensure, in those cases where the hydraulic cylinder is in a position other than the fully moved-out position, that the actuating lever ( ) is held to prohibit a rotational movement of the setting element ( ) relative to the hollow cylinder. The rotational movement would effect a change in the length setting.

Side strut for a lower steering arm of a tractor

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