I have a 6620 corn machine and want to harvest Dry Beans. Other than some perforated screens and a slow down kit for the cylinder, what else can I do to keep my tare down and quality good??? Do you take filler plates out? What kind of settings for fan, ect.??? Any help on this would be greatly appreiated!!!!! Also any little add-ons or tricks to make harvest better would be great. Thanks.
