I bought a 2188 combine in 2007 and have never been able to clean the grain sence we bought it. we have had 4 diffrent case ih companys to look at it but could never find anything wrong with it. Does anyone have any advice
Depending on variety and conditions i can get a very clean sample in wheat. There are some varieties that cause white cap issues. We do have the standard rotor though. Cant help you on the other crops.
For small grains we run cover plates in the first three sections of the concaves to help thrash better. We also added an air deflector from www.Harvestservicesltd.com Look in service bulletin. If you do what they recomend you can do pretty good.
