Were having problems with losses with milo this year with our 2188. It seems like we've tried everything and cant get things under control. This is in 80 to 100 bushel dryland. I think the main place that we are loosing it is over the rotor. I've tried closing the concaves down quite a bit and tried slowing the rotor down and speeding it up and neither is seeming to make the losses any better. Slowing ground speed and picking it up isn't seeming to make much differnce. The best settings so far have been to have the rotor at about 600, fan about 1150 to 1200, chaffer about 9/16 and shoe about 3/8 and runnung around 3.5mph with a 30ft platform. Were running large wire concaves and keystock grates. What setting and are you getting the best results with?
