Abstract
A self-propelled harvesting machine includes an internal combustion engine and an electronic control arrangement that is coupled to the internal combustion engine and that is provided as input the rotational speed of the internal combustion engine and that can be provided with information as to whether the harvesting machine is in operation on public roads or in a harvesting operation. The control arrangement provides as input during the harvesting operation in an automatic operating mode the rotational speed of the internal combustion engine as a function of the situation in a harvesting operation of the harvesting machine as controlled by the control arrangement. In addition, the internal combustion engine can be operated in an efficient operating mode at a local minimum of the specific fuel consumption.
