I think $5K is a steal for this tractor. How many hours are on the clock? I have an '85
L2250 I bought new in that year, and have had it for 23 trouble free years now. Granted, it leads a good life, spending 95% of the time under cover.

I only have about 410 hours on it, and have run Amsoil (synthetic) 15/40 diesel/marine pretty much since new.
Good luck, should you decide to buy it.
