Abstract: The disclosure relates to a mobile working machine comprising a driver's cab for accommodating an operator of the mobile working machine, a control station for the operator arranged in the driver's cab, a primary steering system arranged in front of the control station in the direction of travel of the mobile working machine, and a secondary steering system, arranged laterally offset from the control station in the direction of travel of the mobile working machine, wherein the primary steering system has a steering column section, which cooperates with a steering column mount to transmit a steering actuation to a control unit implementing the desired steering movement, wherein the steering column section and the steering column mount can be connected to each other in a rotationally fixed manner via a plug-in connection, such that the operator is able to dismount the primary steering system depending on a perceived visual restriction.
