A combine harvester has multiple working mechanisms for carrying out specific treatment subprocesses of an overall treatment process for processing crop and a driver assistance system for controlling the working mechanisms, which includes a memory for storing data, a computing device for processing the data stored in the memory, and a graphical user interface. The driver assistance system, together with the particular working mechanisms provided for carrying out the treatment subprocesses, forms independently operating automated adjusting mechanisms which are utilized for optimizing the control of the working mechanisms for carrying out the treatment subprocesses. A process supervisor is assigned to the driver assistance system for controlling individual automated adjusting mechanisms and a data exchange of the automated adjusting mechanisms with one another. The process supervisor is configured for interacting with an operator to edit at least one parameter of at least one control process, which has been stored in the memory for actuation by the process supervisor.
