Abstract: A combine harvester for carrying out an agricultural harvesting process has a plurality of working units and a driver assistance system for controlling at least some of the working units. The combine harvester accommodates as working units a chaff cutter for comminuting harvested produce and a produce distributing arrangement in the rear area of the combine harvester downstream of the chaff cutter for distributing harvested produce on the field soil in adjustable throw directions. The respective throw direction comprises vector components of a horizontal throw direction and a vertical throw direction. The driver assistance system is adapted to optimize the control of the produce distributing arrangement by at least one of the substrategies including “throw direction correction” and/or “inclination-dependent produce distribution” and/or “produce distribution in longitudinal direction” and/or “produce distribution in transverse direction” with respect to at least one optimization criterion.

Abstract: A self-propelling combine and a method for operating a self-propelling combine are disclosed. The combine includes a straw chopper for processing a residual flow formed by plant residues, a cleaning device for cleaning a flow of material formed primarily by grains from residual components contained therein, a chaff spreader, and a power spreader. Using the chaff spreader, the residual components separated from the flow of material by the cleaning device are removed. Further, the residual flow, processed using the straw chopper, is ejected using the power spreader. For improved distribution of unutilized plant residues on the field, the power spreader is assigned to the straw chopper at the bottom such that the residual flow leaving the straw chopper is transferred directly to a material inlet region of the power spreader, and the residual components leaving the chaff spreader are emitted into a transfer region upstream from the power spreader.

Abstract: A combine harvester having a chopper configured for chopping crop, which comprises a cutting cylinder fitted with chopper knives, a knife carrier fitted with counter knives, and a rasp bar arrangement. The counter knives and/or the rasp bar arrangement can be moved into a partial stream passing by the chopper. The harvester also has a crop spreading device configured for spreading the chopped-material stream emerging from the combine harvester on the ground in the rear region of the combine harvester, and a sensor unit configured for generating sensor data which represent at least one parameter influencing the spreading quality of the chopped-material stream emerging from the combine harvester. There is a control unit that adapts the position of the rasp bar arrangement and/or the counter knives depending on the spreading quality.

Abstract: A combine harvester which regulates spreading of crop flow on the ground, with the crop flow passing through a shredding and/or a spreading device in the rear region of the combine harvester, is disclosed. The combine harvester includes a driver assistance system, which includes a computing unit and a display unit. The computing unit processes information generated by the machine's internal sensor systems, external information and information storable in the computing unit. The driver assistance system stores selectable spreading strategies to regulate the spreading of the crop flow exiting the combine harvester and one or more of the partial strategies assigned to the respective spreading strategy. The driver assistance system uses the selectable spreading strategies and the partial strategies in order to regulate the crop flow spread on the ground.
