Have never pulled a pan with a JD, but every farmer that runs green around here says the 9520 is the best tractor made before the 9560R. You have to be careful with tracked ag tractors. They do not appreciate slopes, and do not tolerate rocks very well. I am pretty careful with my 95E, and and I have about 1500 hours on my belts and one is on borrowed time, have a bunch of cables broke. A 9520T is quite a bit more expensive tractor then my Cat, for it to pull its weight you're going to want it to gross at least $3000 per day, however that works out per yard. You are also going to want a GOOD operator, a bad one could kill your belts or transmission quick. These type of rigs can move some dirt, but are not as forgiving as a self-propelled scraper.
