I have just started to cut corn with the 7010. I am getting little pieces of cob in grain sample. Corn is 16-18.5 moisture, 180 bushel. Settings: rotor-350, upper sieve-17, lower -14 , concave clearance 3.6, pre-sieve 5th notch, fan 1100. I am also getting a high tailings alarm. What is your sensitivity set to on the tailings sensor? I had no problems with the wheat this summer. I am used to the 88 series. I always had a clean sample. I am sure I have done something wrong. I have played with the settings but can't seem to fix it. Any suggestions would be appreciated.
