7720 Turbo vs. Titan II - The Combine Forum
Apr 20, 2009 · I have heard that the JD 7720 is the most "balanced" combine that J.D. ever built, especially for that era. I don't know every little detail between the two different models, but don't think you would go wrong with either one. The 7720 was is a great combine.
7720 vs 8820 - The Combine Forum
May 10, 2009 · The combine evaluation substantiates my experience running a 7720 II next to a 1680. The Case was smaller in wheat and canola.

John Deere 7720 - The Combine Forum
Sep 14, 2015 · I'd look for a 86-88 model Titan II. They had some real improvements to the adjusters and a few other details making them more durable and easier to adjust. A solid 7720 with about 3-3500 hours will still bring $15-20K in my area. I'd say get the 7720, get your farm operating well, then trade up to a 60 or 70 series when you can afford it.

But if I had the funds I would have went with a 9400 ( 91 or newer ).
