We are looking at buying an older John Deere 9600 or CTS combine. We would be trading our TR75 in on it. I was wondering which combine is better, the 9600 or CTS.We plan to do some custom combining. In our area it is mostly oats, barley, wheat, and canola grown. What are any of your experiences with these machines, good or bad, I need to know what they run like in certain crops and conditions and what would be best.We were also looking at a Case 1680. But I like green better.
