Obviously everybody thinks the tractor they own is the best. Me included. I narrowed down the list to 3 for various reasons, mainly because I had to eventually get to 1. those three were Kubota, Deere, and Mahindra. Had dealers reasonably close was another factor. You buy the tractor, but you're marrying the dealer. So make sure he's a keeper.
Kubota got DQ'd right away, because their "we don't care" attitude evidently runs rampant. Seems to be a recurring theme. Came really close to pulling the trigger on the Deere, but then found out about the exhaust re-gen system requirements, vs the Mahindra and that was a win for Mahindra. Also compared the lifting capacity & bucket size of JD & Mahindra and that was another win for Mahindra. Price was a little better on the Mahindra, (not a huge factor) but the ergonomics of the Mahindra fit me better than the JD. Might be the opposite for you.
I've had mine for almost 3 years now, with 850 hours on it, and not one significant problem, and I work it hard. My neighbor just got the same hp JD, and has had multiple problems, with weeks of down time with 60 hours on his. Not an indictment, just an observation. The warranty on his JD actually got in the way of getting his tractor fixed recently. Part needed to fix it was warrantied, but JD had a back order for 2-3 wks on it, and dealer couldn't substitute another part.
I would suggest you spend a LOT of time with the dealer, not just the salesman, but talk to the shop mgr, or even a mechanic to get a feel for what they deal with on a daily basis. If the dealer is frustrated with the manufacturer (you'll get a vibe if he is, when you talk to them), then that will translate into frustration for you. You probably don't need any more of that in your life.
I wish I had "played around" more with each of the tractors I was considering. Hook up implements to see how easy/difficult it is, and believe me they are NOT all the same. Go over the entire tractor from bumper to 3 pt hitch, over, under, and see how easy the maintenance that you want to perform is going to be for you. Tractors will last a long time if you do good maintenance on them.
Sounds like you're going to use a fair amount of PTO implements, and least in frequency. How easy is the PTO hookup? I have a friend who has a tractor where the PTO spindle cannot spin freely, even when not engaged. You have to spin the PTO shaft of the implement to get the spline fittings to line up. Ever try to spin the PTO shaft of a baler? It's little things like this that will drive you crazy if you don't research it before you shell out a lot of money.
All tractors have strengths and weaknesses. Get the one that has the strengths you need, and the right dealer to help you along the way.
Good luck!
