Peter, If you have the standard concaves (large and small wires) it will do fine. The small grains concaves (all small wires) and hard thrash kit will do a better job in tough threshing conditions. Peterson chaffer is definitly a plus but the standard sieve (13_16" I believe) should do just fine. Also make sure that the bubble up auger has been updated if it needs it. Hope this helps Proto
