A device for stabilizing the two lower steering arms (,) of a tractor, with the lower steering arms (,) actuated by a hydraulically operated power lever (,). The arms are each associated with a side strut (,) with a first single-acting hydraulic cylinder (,) for stabilizing and fixing purposes. A line connection between the first single-acting hydraulic cylinders (,) and the power lever (,) can be effected by a control valve (,). In order to center the lower steering arms (,) and set the arm to a pre-determined dimension of spread, even when no implement is attached, the line (,) which leads to the second single-acting hydraulic cylinder (,) of the power lever (,) contains a pressure-controlled first return valve. A bypass line (,) with a second return valve (,) is provided to lock in the direction opposite to that of the first return valve.
