[AT] [Farmall] Super M Fan Belt -- and other fun stuff

[Cecil Bearden]

I would bet it has a propane head and pistons in it.   It probably had an 
aftermarket conversion and a tank on the front before you got it.  Or, 
propane tractors do not sell very well, and gas tanks and hoods are easily 
avalable in the salvage yards, so it probably was changed to gas.
