A steering system for motor vehicles including agricultural machines is provided. The system includes a first conventional steering assembly for the front wheels to rotate only each of the front wheels within a respective first predetermined steering angle, each front wheel rotatable to a pre-determined first maximum value within its pre-determined angle. The system also includes a second steering assembly to independently steer a front axle and the front wheels within a second pre-determined steering angle. The second steering assembly is activated only after each of the front wheels have reached its respective first maximum value within its first pre-determined steering angle, during the conventional steering performed by the first conventional steering assembly.
