I own A 8780xp and have put a littel time in a 9690. The 9690 has the better fan,better hydro,bigger grain tankand heavier rear axle and hubs.The rotor is an improvement in tougher crops but I don't think you will see much difference in easy threshing crops. I like the cab on the 8780 better and where they put the air conditioning is easy to clean and service.On the 8780xp the brakes are on the final drives whitch is better in the hills. If you break A drive line you still have brakes and I cut 30% plus hills.
