Abstract: A multiple-axle steering system for an agricultural machine with at least one primary-controlled axle and at least one secondary axle, where the latter's steering deflection angle varies along a progressive characteristic curve as a function of the primary-controlled axle's steering deflection angle. The variation in steering deflection angle along the progressive characteristic curve means that the steering deflection angle of the primary-controlled axle in a range around the zero or neutral position initially results in only a slight steering deflection of the secondary axle. As the steering deflection of the primary-controlled axle increases, the steering deflection angle of the secondary axle progressively approaches the steering deflection angle of the primary-controlled axle. When using all-wheel steering, the use of the progressive characteristic curve facilitates smooth steering when driving on the road, where usually minimal steering deflection is performed by the machine operator.
