Has anyone fabricated a snow cat from a tracked snowblower to tow themselves and gear ? I've seen a couple on you tube with the blower section removed. I'm looking for advice on which make/models to look for that might have the best qualities for this purpose.Fastest forward gear, best flotation on snow and traction , steering capability, possibly full handle bar instead of individual grips ( saw that on an older Craftsman) . Heavy duty Hydrostatic or other drive system . I thought I might get away with a $400 purchase instead of a $4,000 Cdn. Snow Dog . ( Don't really want to get into snowmobiles again) Thanks!
