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 and a computing device for processing the data stored in the memory, wherein 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, wherein 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.
