1926 Snow Tractor
You're not gonna believe this..............
Talk about ingenuity!
This is a 1926 silent film (on video) of
invented by Henry Ford, who is shown driving it.
Watch the whole thing. Note the "hat." And tie!
Our modern snowmobiles are far better
but Henry's machine is pretty clever for the time.
I know we have seen this before, but I don't recall it being so long of a film. I have to wonder about the fact they say Henry Ford invented it. I would doubt that he would have demonstrated it on a Chevrolet touring car! But talk about a model T and it would be an interesting thing to see..
The link did not work for me, but there is a fairly long thread
with I believe the same video as well as photos and patent
documents at this link.
Should have mentioned that at the first link at the
thread I posted, that link to the video is also broken,
but the second link works fine.
