CLEANING SHOE FOR A COMBINE Abstract of the Disclosure In a cleaning shoe arrangement for a combine, an elongated grain pan includes a screen portion and receives crop material directly from an open threshing concave and a return pan under the straw walkers. The screen portion is provided with an under air blast and the grain pan thus does double duty - as a conveyor and as a precleaned or "conditioning sieve". Clean grain passing through this screen portion yokes directly to the clean grain auger of the cleaning shoe. Remaining material, conditioned and stratified by its passage across the conditioning sieve of the grain pan, is delivered to a chaffer. Beneath the chaffer, a sieve assembly includes a conventional sieve portion and, extending downstream beyond the chaffer, a chaffer extension coplanar with the sieve portion and spaced from it by a transverse tailings slot, disposed above the tailings auger of the cleaning shoe. The chaffer and sieve assembly are provided with a conventional air blast from the cleaning shoe blower.
