A side strut (5) for a lower steering arm of a tractor has a single-action hydraulic cylinder and a setting unit with a hollow cylinder (17) and an adjustable setting element 20. The setting element (20) includes a threaded bore (30) which receives a threaded rod (32). The hydraulic cylinder has a first attaching element (6) to connect to a tractor. The threaded rod (32) has a second attaching element (7) to connect a lower steering arm. In the fully moved-out position of the hydraulic cylinder, the setting element (20) is rotatable by an actuating lever (33). Thus, the threaded rod (32) moves in and out. To prevent any rotation, a first holding element (36) is provided. The actuating lever (33) engages the holding element in a rest position. A second holding element (37) 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 (33) is held to prohibit a rotational movement of the setting element (20) relative to the hollow cylinder. The rotational movement would effect a change in the length setting.
