NC Iowa Thompson | Toward the end of last year my grain started getting dirtier and dirtier, I tried just about everything the book tells to do, still dirty sample, had into a shop this summer and mentioned the problem I am having, they have checked all the sieves and say they are good , started combining today , put new fan belt on and made sure it was clean to move speed .set fan at 1050 , rotor speed 625 concave set at book setting , top sleeves set by book around 17 mm? bottom set 10 mm or what ever the book says , still very dirty . Kind of at a loss what I am missing? Any suggestions ? |
