Abstract
An airflow system for a rotary harvester includes a cleaning charge fan assembly, a cleaning fan assembly, and bonus sieves with fan assemblies. Each of the fan assemblies is powered by a hydraulic motor. By linking the charge fan motor, the left/right tailings fan motors, and the cleaning fan motor in a series hydraulic circuit, each of the motors will increase/decrease in speed at the same time and by the same proportional amount.
