Trivia: a Johnny Popper is a John Deere model M. I am currently in the process of restoring one. It is called a popper because of its distinct sound, caused by the non-180 degree angle between the two cylinders on the camshaft. I dream about every day to become a farmer.

Excellent. Those tractors were rockstars, and ran for years and years. I can still recall that popping sound in my head, many years later. Very distinctive.
