Nice idea.

But with the available materials at the time it was probably prone to often break the chains on the rotors.

Geweldig !! We zijn even in 1924. ( is 89 jaar geleden. )
In dit filmpje zien we een : sneeuw mobiel. Die rijdt op een meter dikke sneeuw laag.
Dit voertuig maneuvreert zich makkelijk op de dikke sneeuw laag. En is ook nog eens zeer sterk.
Zie de grote boomstammen op de slede's, die worden voortgetrokken.

Awesome! We are here in 1924. (Was 89 years ago.)
In this video we see: snowmobile. Who rides a meter thick layer of snow.
This vehicle maneuvreert easily on the deep snow. And it is also very strong.
See the big logs on the carriage, which are to be drawn.

I just love the epic music! It also share a resemblance to the Star Ships in Star Trek, like Enterprise, Voyager...
