I cannot tell you how the CTS 11 is on corn, but on wheat, barley, oats, peas, beans, canola, and other cereals....the combine works great. There are quite a few of them up here in Western Canada, and everyone that I talk to love them. I've ran one for a friend on my own crops, and I'd say it has more capacity then a 9600 J.D., with a much cleaner sample then the 9600, and less over the back, especially in crops like barley. It has 275.h.p. and is super in tough conditions. I cannot figure why Deere did not push these more.
