Snow Trac's and Snow Masters will often pick up rocks or branches and tear or dent out the front fenders as that is the narrowest point the track passes. Ron Hoffman of Yakima Wa has had his white ST4 for some 15 years and the previous owner cut slots in the front fenders, just below the headlights. In deep fresh new powder it blows snow out both front fenders and looks like a little " Snow Dragon". It looks Wild! I've got it on vedio tape. His is a 63 with a built up 1700 CC engine.
