摘要：
A combine harvester may include a chaffer to separate residue from grain in crop material, a fan to direct air through and across the chaffer to carry the residue from the harvester, a sensor to output signals indicating a characteristic of the crop material upstream of the chaffer and a controller to adjust a speed of the fan based on signals from the sensor.
