Interesting old video.
Wonder if this concept would work on a pontoon type boat?
May have to build a model of one to see.

Hi
Interesting, there was a radio play recently about Geoffrey Pyke's Habbakuk Pycrete ship project, but he also designed a troop carrier called the Weasel and the first prototype used an Armstead instead of tracks .

Funny you mentioned a Weasel as I had shown this to Rick earlier today.

I wouldn't like to fall off that tractor,imagine what it could do to a person
In the 60's a similar thing was used on a much bigger machine for use in bogs and swamps.It used rollers with much sharper"tines",actually more like a huge machine screw thread.It was like a huge platform,with the driver perched on top.It was lauded as being the best thing since sliced bread,but I don't think many were sold.
I'm sure someone knows the machine I mean,as it crops up in various bits of film of that era.

Saw this one in a tractor museum near Sacremento.
