A combine harvester having a frame and a crop harvesting header supported by the frame to gather crop material. A threshing and separating mechanism connected to the frame that receives the crop material from the header to thresh and separate the grain. A shoe assembly positioned beneath the threshing and separating mechanism to receive the threshed grain connected to a drive that affects fore-and-aft reciprocating movement of the shoe assembly which conveys grain rearward. A flexible seal attached to the underside of the shoe assembly across the width of the shoe to obstruct air from flowing under the shoe assembly.

What is claimed is: 1. A combine comprising: a frame mobilely supported over the ground by wheels; a crop harvesting header supported by the frame to gather crop material and convey to crop material rearwardly; a threshing and separating mechanism on the frame that receives the crop material from the crop harvesting header to thresh the crop material into threshed grain and to separate the threshed grain; a shoe assembly positioned beneath the threshing and separating mechanism to receive the threshed grain and connected to a drive that affects the fore-and-aft reciprocating movement of the shoe assembly to convey the threshed grain in a rearward direction; and a flexible seal that is attached to an underside of the shoe assembly across the width of the shoe to obstruct air from flowing under the shoe assembly. 2. The combine of claim 1 wherein the flexible seal is supported by attachment members that are attached to lateral sides of the shoe assembly. 3. The combine of claim 1 wherein the shoe assembly has a lower shoe that receives the threshed grain and transports the threshed grain to grain augers on the frame of the combine. 4. The combine of claim 3 wherein the flexible seal is of sufficient length to fold over and contact a portion of the combine in between the augers. 5. The combine of claim 3 wherein the flexible seal includes a slack portion that extends upward and forward from the seal toward an interface with a surface of a side stationary seal. 6. The combine of claim 5 wherein the slack portion of the flexible seal is attached to a pivoting side seal support such that the slack portion permits a portion of the flexible seal to reciprocate with the lower shoe and another portion of the flexible seal is attached to a pivoting but non oscillating structure. 7. The combine of claim 6 wherein the pivoting but non oscillating structure is the pivoting side seal support.
