Threshing section -- P1, about 44" -- P3, about 39" ........ Separation area -- P1, about 33" -- P3, about 44" -- Discharge is about 12" on either version. This only applies to the larger machines, N5 thru R72. Feeder houses approximately match the widths of threshing sections. Actually, it's all separation area after the material has left the concave surface.
