I would be happy to share settings with you. I run bean modules in the front two spots on each side ( bean modules are smooth with long oval holes from Case-IH ). I set my front modules so that they are even or just a bit tighter than my back modules. My sieves are actually the longer opening corn seives which allow me to run pretty tight and not throw beans over. I think the top seive is somewhere around 3_8" and the bottom is just tighter than that. The tailings processor door stays closed, elevator speed is set to slow, feeder house chain is serrated (same chain they put on when they took it back to Moline for updates). I do not have a rock beater installed on my machine. My dealer and area rep where worried that it might cause too many splits in beans, so I wonder if that could be part of your problem. I made a feeder house floor out of Picket auger flooring, so it has elongated holes, which allow more material out, and I also put on my screened auger troughs. I normally run my rotor at 300, but last night I was in some pintos that I needed to speed up to 330. My fan speed is run between 950 and 1050. I hope this helps you, and let my know if I can help again. When will you start corn harvestIJ I think we are about two weeks away, but soys are turning fast, so we will keep the conbines running I am sure. Good luck and let me know how you turn out.
