THAT is a real question! "It depends" of course. I have zero experience with Agco on subcompact, lawn machines, etc. I do have experience on larger (70-90hp) equipment where it is a mixed bag. Probably not a lot different than Deere, New Holland and Kubota. Examples: 1) Brake discs for expanding the braking ability of a 2660 for use on steep ground -- dealer had almost enough in stock and had to wait for several weeks for the rest to come from AGCO. 2) Loader valves -- a disaster story --- their "depot level maint. supply chain" seemed to have ignored the fact that many of the DL250 loaders control valves were defective on brand new tractors. Dealers with terrific strong knowledge reputations tried all manner of things to fix the problem (bucket would not force nose down.) Finally replaced the $1100 valve by getting a new one from AGCO stock. No change. Same problem. I finally went to the valve manufacturer, bypassing AGCO, who admitted the problem, sent me a kit which I installed & fixed it myself. I know of at least 4 tractors with the exact same issue, brand new. Pee poor, but then that is only one example. I have no way to know the overall picture. I cannot over emphasize the value of a good dealer with deep experience in the shop. I will say that the regional service rep in AGCO (been thru two of them) was always cooperative, always understood the technical issues, and eventually "made it right" no matter what the (more serious) problems were. That's really about all you can ask. I can definitely give you a horror story seen or heard on every single one of the top 4 brand "medium size utility tractors." My guess is that the biggest variable is the dealer and that AGCO is about on a par with any of the four.
