I have went through a lot of different combines trying to find that runs as cheap and reliable as the old 2388. The 580r worked good, but it seemed to take alot of screwing around to get to. It took 2 football fieds to turn it around too. I would want a dealer pretty close, there is losts of parts. The 9090 i ran it for 2 years, the first year was dry good going but the second was not. Liked it the first year but the second year was tens of thousands of dollars to keep it moving while my brother in law with a 4000hr tr 98 is lapping me all day. They are a good, good condition combine, no good for tougher stuff. I had a 7010, it was a good unit, easy to set, good on fuel not too may problems. Then the 8120 came, i thought case would have fixed the few issues that were on the 7010 but no they made them worse. Air cleaner, feeder chain, and that crappy spreader system, and chopper bearings( just put regular bearings in not the fancy case ones and you wont have that problem). I honestly don't know how they sell any combines after the 20 series. I think the case rotors and shoe are too short if you push them its easy to make it go out the back. Massey's. 9790 great combine, crappy cummins motor, 9895 good combine fuel pig of a cat motor. 9560 massey great combine, easy to set, cheap to run and it will do way more than any combine we have had in a day. Cheap on fuel and it will it can handle our tough condions. I have 2 of them now, i have never liked a combine enough to get a second one of the same thing.
But pick the dealer you want to deal with, and go with it. A crap dealer will make a good combine crap.
