The screw conveyor is operable to define an upturning side and a downturning side. The grain tank includes a floor section that covers the upturning side to prevent back flow and the formation of a stagnation zone in the vicinity thereof. ## Claims ### Claim 1 A combine harvester comprising a grain tank having an auger trough in which a cross auger of an unloading system is disposed, the cross auger being operable to define an upturning side and a downturning side, wherein the grain tank comprises a generally planar floor panel having a discharge edge parallel to a rotation axis of the cross auger, wherein the generally planar floor panel covers the upturning side and leaves the downturning side exposed. ### Claim 2 (depends on 1) The combine harvester according to claim 1, wherein the auger trough is disposed transversely with respect to a forward direction of travel of the combine harvester. ### Claim 3 (depends on 1) The combine harvester according to claim 1, wherein the generally planar floor panel slopes downwardly towards the auger trough. ### Claim 4 (depends on 1) The combine harvester according to claim 1, wherein the upturning side is covered across a full width of the auger trough. ### Claim 5 (depends on 1) The combine harvester according to claim 1, wherein the auger trough resides adjacent a front side of the grain tank. ### Claim 6 (depends on 5) The combine harvester according to claim 5, wherein the downturning side resides adjacent the front side. ### Claim 7 (depends on 1) The combine harvester according to claim 1, further comprising a turret unloading system having an upright conveyor configured to be fed by the cross auger located in the auger trough, and a horizontal conveyor which is pivotable about a vertical axis between a transport position and an unloading position, wherein the horizontal conveyor is configured to be fed by the upright conveyor. ### Claim 8 (depends on 1) The combine harvester according to claim 1, wherein the discharge edge is directly above the auger trough. ### Claim 9 (depends on 8) The combine harvester according to claim 8, wherein the discharge edge is directly above the rotation axis of the cross auger. ### Claim 10 (depends on 1) The combine harvester according to claim 1, wherein the auger trough comprises a rear wall panel below the generally planar floor panel. ### Claim 11 (depends on 1) The combine harvester according to claim 1, wherein the auger trough is below the generally planar floor panel. ### Claim 12 (depends on 1) The combine harvester according to claim 1, wherein the cross auger is below the generally planar floor panel. ### Claim 13 (depends on 1) The combine harvester according to claim 1, wherein the generally planar floor panel covers the upturning side of the cross auger directly opposite the exposed downturning side across the rotation axis of the cross auger. ### Claim 14 A combine harvester comprising a grain tank having an auger trough in which a cross auger of an unloading system is disposed, the cross auger being operable to define an upturning side and a downturning side, wherein the grain tank comprises a generally planar floor section having a discharge edge parallel to a rotation axis of the cross auger, wherein the generally planar floor panel covers the upturning side and leaves the downturning side substantially exposed. ### Claim 15 A combine harvester comprising: a grain tank having a generally planar floor section extending over an auger trough; a cross auger disposed in the auger trough, the cross auger being operable to define an upturning side and a downturning side, wherein the generally planar floor section has a discharge edge parallel to a rotation axis of the cross auger, and wherein the generally planar floor section covers the upturning side and leaves the downturning side substantially exposed. ### Claim 16 (depends on 15) The combine harvester according to claim 15, wherein the generally planar floor section slopes downwardly over the auger trough. ### Claim 17 (depends on 15) The combine harvester according to claim 15, wherein the discharge edge is directly above the auger trough. ### Claim 18 (depends on 17) The combine harvester according to claim 17, wherein the discharge edge is directly above the rotation axis of the cross auger. ### Claim 19 (depends on 15) The combine harvester according to claim 15, wherein the cross auger is below the generally planar floor section. ### Claim 20 (depends on 15) The combine harvester according to claim 15, wherein the generally planar floor section covers the upturning side of the cross auger directly opposite the exposed downturning side across the rotation axis of the cross auger.
