I would like to know everyone's thoughts on 8000 series tractors compared to the 4955 or 4960. I understand the cab is nicer on the 8x00, but I am more concerned about my ability to keep it in the field without a Deere service tech. Will the 8000 put power to the ground better enough to put up with the electrical issues. The increased hydraulic flow would be a benefit to me as well. How accessible is the transmission if I need it on a table? I understand the routine on the 15 speeds in the 55/60 series, but don't know how the 8000s are serviced. Are the 8.1 engines that much of a longer life engine. We have been looking at higher hour tractors and initially we have been looking at buying and rebuilding after first season, and then I read people saying they are 13-14000 hrs and untouched. I'd just like to know your thoughts from a mechanical standpoint. In the long run am I just better off with a 4960 with the fuel set up a little to match a 83/8400
