1. An agricultural working machine comprising:

  • a first axle disposed at a front of the machine;

    a second axle disposed at a rear of the machine;

    multiple ground-engaging means disposed at the first axle and the second axle, wherein the multiple ground engaging means are configured to be drivable by a drive engine or are configured to be steerable using steering-knuckle steering means or are configured to be both drivable by a drive engine and steerable using steering-knuckle steering means;

    at least one steering-angle sensor disposed at an associated steerable ground-engaging means for detecting a set steering angle (δ

    th) of the associated steerable ground-engaging means;

    at least one steering brake for the selective braking of one or more of the drivable ground-engaging means on the second axle for steering support; and

    a controller for controlling and regulating the at least one steering brake;

    wherein a slip angle (α

    ) of the steerable ground-engaging means is determined, and the controller is configured for automatically activating the at least one steering brake during a turning action of the agricultural machine in response to an operator turning a steering wheel, depending on the slip angle (α

    ) or both the set steering angle (δ

    th) and the slip angle (α

    ), wherein based on said configuration of the controller, manual activation of the steering brake during the turning action is not required, and the turning rate can be increased due to activation of the at least one steering brake.
