Abstract: An agricultural work machine, such as a harvester, is disclosed. The agricultural work machine includes an internal combustion engine, at least one working assembly, and a regulating device. The internal combustion engine provides power to the working assembly, with the internal combustion engine being operated in different power settings, with a different performance characteristic in each of the different power settings. The regulating device causes automatic shifting of the internal combustion engine from one power setting to another in response to determining that the power requirements assigned to the working assembly change. The power settings may be assigned to different, pre-selectable power setting ranges, which may differ in terms of the highest respective power setting assigned thereto. Further, the regulating device may only cause shifting of the internal combustion engine between power settings in the respective pre-selected power setting range.

Abstract: Plant material for ensilage is harvested using at least one harvesting vehicle in the field, is hauled to a silo and is compressed using a compression device. The compression output of the compression device is compared to the harvesting output of the at least one harvesting vehicle, and a command to increase the harvesting output or to decrease the harvesting output of the harvesting vehicle (1) to a non-vanishing value is generated when the harvesting output deviates significantly from the compression output.

Abstract: A monitoring device for at least one auxiliary assembly which influences the exhaust-gas quality of an internal combustion engine and consumes a resource in order to attain a desired quality of exhaust gas, includes at least one sensor for measuring a variable related to the resource, and an arithmetic unit for estimating the current quantity of the resource on the basis of the variable measured by the at least one sensor, and which is designed to calculate and indicate an operating capacity of the internal combustion engine that remains before the resource is depleted. Potential resources are the absorbance capacity of a particulate filter and/or the quantity of an ammonifier that is available.
