Cruiser mate, this tractor issue apparently pushes one of your buttons. Why? Heard a lot worse and never heard of the tractor story. But now you actually brought it up....

Maybe not the 4.0L I6 but the 4.2L I6 came pretty close to being a "tractor engine":

Holy crap... he's right. Looks pretty familiar.
I did some looking around. Apparently it's known for its reliability. Go figure lol

Some tractor companies did use car engines. I once bought a small block Chevy that was in a combine. The only thing that was different was the exhaust manifolds were upside down and rotated. I think I would buy a tractor if it had the 4.0 in it.
