20 Bottom IH 800 Plow at the 2015 Half Century of Progress Show pulled by a pair of Massey Ferguson 4wds. The lead tractor is a Massey Ferguson 5200 and a Massey Ferguson 4880 is hooked to the monster plow. The Massey Ferguson 5200 and 4880 both have power shift transmissions which allows them to adjust in unison to move the 20 bottom plow.
