I just picked this up a couple days ago, I was lost and spotted it under a tree, went home and thought about it then went back the next day and offered to buy it and got it, its in good nick under 300 hours on the clock, I think it was parked because of an exhaust valve problem, the valve is totally stuck now and moisture has gotten down the exhaust.
Seems to be a pretty neat tractor, it has 2 fuel tanks one for kerosene and one for gasoline, and a very strange carburetor, it has a hydraulics and a rotary hoe.
I am trying to find a manual and somewhere that sells parts, I need a gasket set as I will take the head off as I need to deal to that exhaust valve
