WOW! The Mahindra boys are T.O.U.C.H.Y. 'bout their tractors!
Not to be commenting on post's by others, but you didn't hear ME say anything NEGATIVE about them. Just POSITIVES about a known excellent product from Massey Ferguson. After ALMOST an entire lifetime around this sort of tractor, I know where I'd bank MY money.
Warranty being what it is, I STILL think the MF is a better buy, ESPECIALLY if you can get one @ $8000 or under w/ low hours. These tractors are rock solid. If there was any issues they would have surfaced by now. Sure, there's still a chance of a little part breaking, but a SLIGHT chance, unless there's abuse in the future. These are just that sound of a small tractor. In the end, you'll have a tractor that is well known to hold its value for several generations, not just a few years. You'll have what is considered THE BEST small diesel in its class. Mahindra's might be a good tractor, but that particular model of Massey is a GREAT tractor with a GREAT reputation, known far beyond the normal circles of tractor experts/enthusiast's. That great rep translates into re-sale value.
Point being, take 'em both, use 'em hard for 10 more years and see which one will best return your investment.
I'm still using a 36 year old rendition of that Massey Ferguson almost every day in my mowing business. I'd stack it up against most any NEW tractor for reliability, dependability, fuel efficiency, and ease of operation. You're look at one of the all-time greats as far as small utility tractors go.
