Abstract
A self-propelled crop harvesting combine having a variable speed crop threshing and separating rotor. The crop material is delivered from a conventional cleaning system into a grain holding tank. A system is provided to determine the ratio of damaged to undamaged grain from predetermined amounts of grain delivered to the grain tank. An electronic control system varies the speed of the rotor in response to changes in the ratio whereby the speed of the threshing mechanism is automatically varied to minimize grain damage in the threshing process.
