Thanks so much for your info! your a mountain of knowledge on this tractor! as for the temp sending unit, mine doesnt have one, nor does it have a light.(after long and hard looking) panel has oil, fuel, charge, and glow plugs lights. am trying to figure a way to mount temp guage somewhere(maybe in upper red hose). so how do you like your tractor, and what kind of implements do you have for it? have you had any problems with it since ownership, and have you found a good place for parts? so far all i have for mine is a 5ft finish mower. its a little large, so i am thinking of maybe trading for a 4ft if i can find one. once again, thanks a million for the help, and i will definately keep in touch on this forum. By the way, i see you are in OKC. i am about 2 hrs away in Beggs. funny, huh?
