The "horse power" thing got my curiosity up, did some looking around.
Found this on Wikipedia:
In 1993, R. D. Stevenson and R. J.

"It's a 64 Ford Super Dexta", he said. "It's a tough little tractor, although it's a hard starter being a diesel and all." He did manage to get it running, compliments of a can of ether. Once started it putted along pretty good. It
