Obsolete - 10/22/2014 18:39 I borrowed an 8410T last fall and got a headache from the jarring and pounding. I swore then that I would stay with duals and mfwd. This is a new year, however and I watch the neighbors with the tracks and I see better traction and better flotation so I am wondering about tracks again. Are the Cat 45's and 55's as rough as the John Deere 8000T series? How much better are the John Deere 8000 R T's with suspension? I see that the used Cat's are cheaper than the JD's. Is there a reason for that? And Case IH guys, go ahead and chime in about the quads...I'd like to hear what you have to say.
