ABSTRACT OF THE INVENTION A grain harvesting combine is provided with an improved sieve plate for more efficient cleaning of the grain. The sieve plate is mounted on the combine adjacent the rearward end thereof and is substantially rectangular in shape. The sieve plate has forward and rearward edges and opposite side edges, the forward edge and side edges being substantially coplanar. The sieve plate also has a forward portion which slopes downwardly from the forward edge and terminates in a substantially flat portion extending rearwardly to the rearward edge. Inclined opposite side portions are also provided which slope downwardly from each side edge to the flat portion of the sieve. The degree of incline of the forward portion and side portions is approximately 5° from the flat portion. The inclined side portions minimized grain loss when the combine is operating on sloping terrain.
