Combines specialty rotor modifications

We did this for a couple of operators in AR a few years ago, pretty much specifically for rice, and it increased their throughput by a good factor, thresh was sustained well, and we believe separation was a little cleaner. But in soybeans, concaves had to be drawn up somewhat tighter for thresh, and in milo concaves had to be set very tightly. In the latter crops rotor speed required RPM which caused some damage, as well, while trash was required to be broken up badly adding to shoe load. I think we learned that the heavier load (rice)was spread out enough for more threshing on it's own stems, etc., but the lighter loads required more beating against the concave crossbars since they wouldn't roll thru in the same way -- probably couldn't feed enough in the front. Hope this makes sense.
