A system for leveling grain on a return pan (128) of an agricultural combine (102), including a plurality of sensors (S1, S2, S3) coupled to the return pan (128) to detect a quantity of grain on the return pan (128) at a corresponding plurality of locations a plurality of grain steering devices (156, 158) disposed on the return pan (128) to steer grain sliding down the return pan (128) and at least one ECU (192) coupled to the plurality of sensors (S1, S2, S3) and to the plurality of grain steering devices (156, 158) wherein the at least one ECU (192) is programmed to read the plurality of sensors (S1, S2, S3), to determine a side-to-side (lateral) distribution of grain on the return pan (128), to calculate a preferred position of the grain steering devices (156, 158) that will more evenly distribute the grain on the return pan (128), and to command an actuator coupled to the grain steering devices (156, 158) to steer them to the preferred position.
