Abstract: A combine harvester includes a belt cutting unit comprising a center belt for conveying harvest to an intake roller and/or to an intake channel of a grain conveyor, and a transverse conveyor belt disposed each on the left-hand side and the right-hand side of the center belt, to convey harvest to the center belt. The center belt, left-hand and right-hand transverse conveyor belts are behind a cutter bar, seen in the direction of travel, with each being operated with an individual belt speed. The combine harvester and/or belt cutting unit has a control unit configured to automatically control the belt speeds of the left-hand and right-hand transverse conveyor belts as a function of a forward travel speed, and the belt speeds of the center belt as a function of the forward travel speed or as a function of the belt speeds of the left-hand and right-hand transverse conveyor belts.

Abstract: An agricultural machine arrangement includes at least one traction machine and at least one attachment device adapted to the traction machine with a driver assistance system optimizing the operation of the traction machine and/or of the respective attachment device. The drive assistance system includes a computing unit and at least one display unit, wherein the computing unit processes information generated by machine-internal sensor systems, external information and information storable in the computing unit. The driver assistance system is structured so that it forms an automatic traction machine adjusting unit and/or an automatic attachment device adjusting unit, wherein the respective automatic adjusting units independently of one another or as a function of one another bring about an “optimization” of the mode of operation of the traction machine and/or of the at least one attachment device.

Abstract: In a device for and a method of calibrating the measurement of a product stream in agricultural machines, a calibrating unit is arranged after a measuring unit, a definite quantity of a product stream is weighed in the calibrating unit and the weight value is determined in an evaluating electronic unit which compares the weight value with a value determined by the measuring unit and determines a correction factor from the comparison of both values.
