I've seen the factory/aftermarket tracks for a Polaris 6x6.
But, they all seem overly complicated and expensive?
Why can't you simply wrap a short set of tracks around the existing dual rear wheels,
(like an old WW2 "half-track" truck) and put airplane-type skis under the front wheels?
Also kinda/sorta like a wide, double-tracked sno-machine?
PS - Argo and Mudd-Ox just add tracks over their regular summer tires.
They don't replace each big tire with a complicated bunch of small wheels?
Just thinkin' out loud!
