I did the engine oil and filter on mine today, and am going to use the SYNTRAN from JD in the trans. My neighbor is a mech for JD, so free delivery and employee discount on the oil. I'm going to change both the filter in the pan, and the spin-on. The only thing used I can find in the cab is the steering column, the turn signal switch, and the drivers seat frame/chain. The wiring harness is new along with the gages and indicators. I think it's about as close to new as I could ever find.
Even the steering wheel is new.
