That a geared or a hydro? If geared should look a lot like my Red Bandit. Check out my topic on that in my signature. Absolutely check out @Crazy_Carl ‘s topic on Red Stag and Ol’ Red in his signature. Maybe look up @Creepycrawler ‘s topic on Rusty.
According to Tractor Data the 800 is a hydro and the Special has a 3 speed Peerless but I see no mention of Hi/Lo so maybe it has a 1200? I'm not sure of what other 3 Speeds there are that were made back then (but I don't claim to know all)
Looks like that tractor was only made for one year in 1971 which is pretty cool! Definitely looks/sounds like a great platform to start with!
