SSC- I used to feel that way about the dropped axe rear end on the older 4110/4115 and newer 2520/2720 series tractors until I started looking at the really large county road graders my county uses (Champion and Volvo). They have the exact same set up on both of their drive axles. If it's good enough for a machine that size, I figure it'll do for mine too. I have never had any trouble whatsoever with it yet. I still say that if you can get that 4310, you'll be really happy with it. It's a great tractor, and can do a lot of different things.
