I am looking at buying a 1994 JD CTS is has 2500sep hrs on it. What are some of the big and small things to look for. The dealer told me over the phone it when through Greenlight when the dealer took it in and they only had to take one chain link out of a return elevator. Are they pretty close to a 9600 with wear and faults? Also how well do the combine barley, wheat, peas, oats, canola?
