I can only tell you about my 8780xp in high yielding wheat 80 to 140 bu.Concaves set at 1_4 inch and run two blanks. The air at max and the bottom sieve at1_2 to 3_4 of a inch and non ajustable airfiol on top.Rotor at 850 to 950.It will cut 1000 bushels an hour and is clean in the tank.Remember if you close the bottom sieve too much you also shut off the air.
