Abstract
Ideal function curves are generated for a combine in various operating conditions having acceptable loss rates. These ideal function curves are stored in an onboard computer and compared with actual measured function curves. The actual function curves are derived from sensors measuring grain distribution per linear length of grain falling through the sieve. The computer compares the actual function curve with the ideal function curve for transmitting an adjustment signal to the appropriate controller to drive the actual function curve towards the ideal function curve. Loss sensors are not required because acceptable losses for various conditions are built into the ideal function curves.
