An apparatus and method for distributing crop material onto a cleaning sieve (24, 26) of an agricultural combine (10). The method includes providing a sensor (42, 48, 54, 56) in connection with a controller (46), the sensor senses information representative of grain associated with a crop material distributor (22) and an inclination angle associated with the crop material distributor (22), and outputs signals representative of grain associated with a crop material distributor (22) and an inclination angle associated with the crop material distributor (22) to the controller (46). The method provides the crop material distributor (22) for distributing crop material from a threshing system (16) onto a sieve (24). The controller (46) determines information representative of grain associated with a crop material distributor (22) and an inclination angle associated with at least one of the crop material distributor (22) and the combine (10). The method includes outputting signals for operable control of operating parameters associated with the crop material distributor (22) and the sieve (24).
