Claim 10:
11. The self-propelled agricultural working machine according to claim 1, wherein the at least one wheel assembly comprises two wheel assemblies on sides of the feeder and designated as front and rear wheel assemblies, wherein the wheels of the wheel assemblies are pivotable relative to their respective axles and about axes which are transverse to the axles to steer the wheel assemblies, and wherein:
the front wheel assembly comprises:
a pivotable base that is pivotably connected to a central location of the axle of the front wheel assembly, the pivotable base being pivotable about an essentially vertical axis, and wherein the deployable drawbar is coupled to and deployable with respect to the pivotable base;
a first tie rod arrangement configured to transfer pivotal movement of the pivotable base to the wheels of the front wheel assembly; and
a first variable length actuator pivotably coupled to the axle of the front wheel assembly and to one of the wheels of the front wheel assembly; and

the rear wheel assembly comprises:
a second tie rod arrangement configured to transfer pivotal movement of one wheel of the rear wheel assembly to the other wheel of the rear wheel assembly; and
a second variable length actuator pivotably coupled to the axle of the rear wheel assembly and to one of the wheels of the rear wheel assembly; and
wherein operation of the first and second variable length actuators of the front and rear wheel assemblies is synchronized, so as to synchronize the pivotal movement of the wheels of the front and rear wheel assemblies.
