An agricultural device for unloading of grain including an unloader conveyor (12) includes a first enclosed housing (38) having an inlet end (32) including an opening (30) for receiving grain. A second enclosed housing (42) having an opposite outlet end (74) includes a discharge opening (76) through which the grain can be discharged. An unloader conveyor element (35) extends through the housing (38, 42) between the ends (32, 74) and is operable for conveying the grain through the housing from the inlet end (32) and discharging the grain through the discharge opening (76). The unloader conveyor element (35) has a first unloader conveyor segment (36) in operative association with a second unloader conveyor segment (40) downstream of the first unloader conveyor segment. A directional transition region (41/141) is positioned between the first unloader conveyor segment (36) and the second unloader conveyor segment (40). At least a portion of the second housing (42) near the directional transition region (41/141) includes a region (78) having reduced cross-sectional area.
