My local CaseIH_New Holland technician that works on my skid steer also works on combines and told me how they were having trouble with the New Holland cleaning shoe in the CR's. This cleaning shoe is the exact same one found in the 8010 too. He told me that in dry corn that was 22% or less the New Holland cleaning system did fine. But in high moisture corn 23+%, it has a lot of trouble keeping it inside on flat or rolling ground. He said it will build up so bad that the air has trouble penetrating the grain and doesn't seperate it and it just goes out the back. I can see that long flat area from the front to the back piling up since there isn't much of a step at the pre-cleaner to do any good. Need a big step at the pre-cleaner with a lot of air to do any good, just like the Deere STS and the lexions have and the CaseIH axial flows. I'm sure the axial flow specialists working for CaseIH and now CNH love the CR systems being pushed on them. I know its driving my mechanic nuts.
