CaptHowdy -- get the email address and the phone number of your AGCO regional service rep. Use it but don't abuse it.
You have to do what seems best given your experience and what you are able to find out/figure out before you trade or buy. I do not wish to influence that, which is your own process. I had "serious lemon level" problems with my MF 2660 bought new in 2011. My situation was disadvantaged by my being 330 miles from my farm and equipment, no dealer near the farm, the closest one there was going out of business, etc. It took forever to resolve what might have been simple and quick if ....me, the dealer and the machine had all been within 25 miles of each other on a continuous basis.
After all the dust settled and all significant problems were finally fixed, I concluded this: The regional service rep was a very reasonable arbiter and judge of the overall situation. Sometimes he was hard to get hold of, but in the long run fair, showed good judgement and saw to it that things were made right. At the end of the far-too-long-process AGCO stood behind every single aspect of what they sold me, extended my warranty when they did not have to, and caused 3rd party dealers to be fair on charges. I reluctantly had to admit that they stood behind it and made it right.
Unfortunately you cannot go out and buy a farm tractor for $30 to $50,000 these days [from any source] and expect it to be trouble-free without repeated rounds with the dealer & sometimes with the manufacturer -- no where near like buying a car ! There is terrific safety in numbers when buying a car (where a million or so of them were sold and heavily regulated by both market forces and the government) and far different when buying a tractor (where 40 or 50,000 were sold MAYBE and outside these forums very darn little is shared publicly!!!) The farm tractor market is just not QUITE big enough to enjoy mass market benefits, especially in remote rural areas.
Thank gawd I was not having to make a living with that tractor. A good dealer can't be overemphasized & is worth their weight in gold. So is a good regional service rep.
