Silver, I've never run a 9000 series machine before but it has to be nicer than the Titan series. I ran a 760 Massey before the 8820 and it was a big difference for the better. I can talk on the phone or talk to another person in the cab while the machine is running without much noise problem. My cab is sealed very well and stays clean during harvest and I almost never have to run the AC on high during early fall afternoons. I'm sure the 9000 combines are really quiet and with the electric controls are really easy to operate. I was looking at 9000 combines when I found my 8820. I looked at the difference in price and have newer heads then what I could have afforded if I bought a 9000 series. You do what you think is right for your comfort and pocket book and I hope you'll be as pleased with your machine as I am with mine.
