I'm not real familiar with tracks but the Viking does put out 47HP......I know sand may not be comparable to snow but I've ridden dunes with real soft sand in 4WD and went up some real steep stuff....granted I had a good run at it but I never really felt the machine bog down so much that I had to abort the hill.
Hope some of that is of some use to you.
