Combine harvester having a driver assistance system

A combine harvester including a driver assistance system that regulates a spreading on the ground of a crop flow exiting the combine harvester, the driver assistance system comprising:

• an arithmetic logic unit;
• at least one display unit;
• a shredding device, for chopping or shredding the crop flow passing through the shredding device;
• and
• a spreading device disposed in a rear region of the combine harvester for spreading the chopped or shredded crop flow on the ground;
• wherein the at least one display unit displays spreading strategies for selection by an operator of the combine harvester;
• wherein the arithmetic logic unit processes information generated by sensor systems disposed within the combine harvester, and processes external information and information stored in the arithmetic logic unit;
• wherein the selectable spreading strategies include spreading strategies selected from the group consisting of uniform crop spreading, chop quality and energy efficiency;
• and
• wherein the driver assistance system implements a particular one of the spreading strategies that is selected by the operator with consideration for the available information, to regulate at least the shredding device and spreading device for uniform spreading of the crop flow exiting the combine harvester, to optimize the uniform crop spreading on the ground, to optimize a chopping or shredding quality of the crop flow exiting the combine harvester or to optimize an energy demand relating to an energy efficiency for the chopping, shredding and spreading of the crop flow.
