The crops semed to have more dust this fall than usual. In our area we attibuted this to having a week of wet weather in mid September which seemed to have caused mold or rust to grow on the plants which turned into a lot of dust at harvest. I'm sure you do not have a hugger. I'm not aware that a hugger cornhead was ever made for a conventional combine. A hugger head has enclosed gearboxes to drive the snapping rolls and chains. I believe yours have chains underneath to drive themIJ You might try to slow down the cylkinder RPM to 300-350. Or close down the chaffer some more. Having pieces of cob in the bin can depend on variety. Some varieties break up worse than others.
