old Henry had something!
"...tractor-snow mobile type machine invented by Henry Ford"
This is a really neat video of a tractor-snow mobile type machine
invented by Henry Ford. Watch the whole thing. It's a video copy of an
old film that doesn't have sound...but it's pretty neat.

I can't get the video up, but I think that Pioneer Village in Minden Nebraska has one, been a long time since I've been there. They have an after market one built around a Model T for sure.
