Agricultural harvester i.e. self-propelled chaff cutter, has control and regulating device regulating driving speed of operating elements, and drive engine providing power with required maximum torque for controlling harvester

摘要

The harvester (2) has a drive engine i.e. diesel engine (14), including a motor controller for operating operating elements. A control and regulating device (19) regulates a driving speed of the operating elements. The engine provides power with required maximum torque for controlling the harvester. Two switchable engine power stages provide preset power output. Speed of the engine within the engine power stages is associated to a reference torque, where the reference torque lies below the maximum torque of the engine.
