1. A self-propelled agricultural working machine comprising:
a feeder at a front of the self-propelled agricultural working machine configured to be lifted up or down;
a header that is detachably coupled to the front of the feeder, wherein the header includes:
a back wall; and
at least one wheel assembly, the at least one wheel assembly including an axle and two wheels attached at the ends of the axle, the at least one wheel assembly being movable between a field position in which the axle is essentially parallel to a longitudinal direction of the header and a transport position in which the axle is transverse to the longitudinal direction;
wherein the header comprises an actuating system configured to move the at least one wheel assembly from the field position to the transport position and vice versa, the actuating system having an actuator mechanism configured to actuate a swivel movement of the axle and the wheels of the at least one wheel assembly to bring the at least one wheel assembly to or from a position wherein in which the axle is transverse to the longitudinal direction of the header, and
wherein the at least one wheel assembly has a deployable drawbar that is pivotable between an essentially vertical storage position and an essentially horizontal deployed position, and a drawbar actuator configured to actuate a pivoting movement of the drawbar between the essentially vertical storage position and the essentially horizontal deployed position, the actuator mechanism and the drawbar actuator are configured so that the pivoting movement of the drawbar is synchronized with the swivel movement of the axle so that the drawbar is brought from the essentially vertical storage position to the essentially horizontal deployed position as the at least one wheel assembly swivels toward the position in which the axle is transverse to the longitudinal direction of the header and vice versa.
