I have been told the track machines are more useless in snow then the tire version. To my knowledge there is no options for tractions devices either. Where as tire chains help the tire machine considerably on ice and snow and studded snow tires are available.
I think the track machine are simular to a monster truck tire in snow (extremely useless) , not a light enough footprint to stay on top and to much floatation to get down to a solid base and find some traction.
Also a good snow tire requires smaller lugs with alot of spaces and a narrow footprint, Where tracks tend to have wide and long lugs with rounded corners to prevent chunking the tracks when working on abrazive surfaces. I guess someone could mold a “snow track”simular to a snowmobile tread, with narrow, sharp tread, but to date I have never seen one.
