Unloader system for an agricultural combine

An agricultural combine with a plurality of grain tanks (12a, 12b, 12c) and an unloader system (14) for unloading grain harvested by the combine. The unloader system (14) has an unloader tube (16), a sensor (46) and a controller (48). The unloader tube (16) includes an interior passageway (18) with a conveyor (24) inside the interior passageway (18) for moving the grain through the unloader tube (16) and at least two discharge assemblies (26, 28) on the unloader tube (16) for discharging grain traveling through the unloader tube (16) to one of the plurality of grain tanks (12a, 12b, 12c). The sensor (46) is used for sensing an attribute of the grain that is to be unloaded through the unloader tube (16). The controller (48) is operatively connected to and in communication with the unloader system (14) and sensor (46) so as to discharge the grain from the unloader tube (16) through one of the at least two discharge assemblies (26, 28) based upon the attribute detected by the sensor (46).
