Mahindra is selling small and medium tractors in the US now; I don't know for sure but I wouldn't be surprised if they were much more user-serviceable than the American brands people are complaining about.
Yeah, Mahindra has some reasonably large tractors on their website, but the really Big Tractors you'll find from say John Deere aren't available. According to Wikipedia they're the largest tractor seller in the world, so maybe they'll expand!
