adam7 - 1/1/2009 16:47 i have to realize it's only a 250 hp. tractor in a big frame and i understand that. The 8570 is the smallest tractor in its frame size. So is your 4560. I haven't compared the power to weight ratio of both, but you will probably be in the same range. If doing the math, just make sure you use either engine or pto hp for both so you get comparable numbers.
