We've got two John Deere Gators, 850d's, both diesels because everything we have is diesel, but they have a new one they came out with that is a fuel injected gas, with 50 Hp goes about 40 mph, our diesels will go 30 maybe 35 but thats fast enough, we use them daily, never thought I would ever buy one, now don't see how we survived with out them, but we have 45 acres and everything is spread out
John Deere's do hold their resale value the best, but you pay more for them in the beginning, I've got about 400 hours on mine, the only problem I've had is parking brake, but I caused it, I was using it for my deceleration brake, and had to replace the pads, and the oil filter is kind of a pita
