  • Combine harvester with even crop distribution
    Patent number: 9345197
    Abstract: A combine harvester has a thresher rotor assembly having a thresher rotor and a grate. At least one distribution device is disposed beneath the thresher rotor and is controllable to deflect grain falling from the thresher rotor assembly in a transverse direction. The distribution device may take the form of stub augers, pivoting plates or sliding plates. A cleaning shoe has a pan upon which grain falling from the thresher rotor assembly impacts. Plural sensors are disposed adjacent the pan and are each arranged to generate a signal indicative of crop load on the pan, wherein the distribution device is controlled automatically in response to the generated load signals.
