Through Thick And Thin

I've seen a similar setup on 20's or 30's cars being used by postal vehicles to get through snow in some of the northern states. It's pretty cool, but I don't imagine it would do too well over anything other than soft terrain.

 

Jim, the screws would have to be counter-rotating. If they were both turning the same way, the vehicle would want to scoot itself along sideways. Although it looks like the screws can be independently reversed, as they are both turning the same direction in the shot of it going sideways — that or one of them was freewheeling.
