our 8640 has the best air conditioner of any piece of equipment we have. Yes reverse sucks, and A range is about all that is usefull, even A is too high at times being that we do alot backing with a tile plow.

I like operating the tractor, hate all of the bad talk that goes on about them, but I understand that it will probably need repairs in the future, ours really has'nt been that bad, 7800 hours and everything works.
