I have a 1988 650 complete with loader and BH. I am toying with the idea of trading it in on a 2520, which would also be complete with FEL and BH. I bought the 650 new and it has been a flawless tractor and still is. I am curious as to the reliability and pure ability of the 2520. Two things that set me back on the 2520 is the split-level rear axle and the fact that it’s weight is only 10 pounds more than my 650 and the 650 is a smaller tractor and only a 2 cylinder diesel. Any comments?
