Our family own a steal wheel,red hub, hoppin johnny, When I was at Purdue, the Agricultual Engineering Department, restored it to new condition. John Deere, got us every original decail, blue prints, old rubber seals (no that neoprene crap), and they gave us rubber tracks to put on the wheel tines so that we could run it on paved streets, for parades. It is truly an American icon!
