Does anybody have a hot setup that works well for wheat only? Bought this 7230 new last year, would like to improve it. What are you using for concaves, rasp bars, and so on, that improves performance. I've been reading on here about the airflow kit on older flagship models, and was wondering if that would be the same on the 30 series. We have high yielding irrigated wheat, about 120-150 bu. I think that this combine can perform better than it does.
