Abstract
A combine harvester having an engine, a traction drive transmission, a header, and a threshing and separating mechanism, is disclosed wherein the combine is provided with a machine throughput control system including a machine loading control loop operable to produce a signal representative of machine loading, and a grain loss control loop operable to produce a signal representative of grain loss. A grain loss controller is continuously operable to establish a causal relationship between machine loading and grain loss. The machine loading signal, the causal relationship current with that machine loading signal, and a reference loss signal is applied to the grain loss controller to derive a reference machine loading signal. A machine loading error signal, produced by summing the representative machine loading signal and the reference machine loading signal, is used to control the machine throughput.
