My snowmobile has a much harder time with tight turns on well-packed snow than in deep snow. You turn the skis and it just keeps going straight. In deep snow they actually have something to grab into and it turns quite well. But it's a Skandic SWT, so not your average snowmobile. On the other hand it's not much use once the snow's gone. The tracked ATV idea seems like a win in both departments.
The guy I bought the Skandic from replaced it with
one of these. Wow!
How is that Bombi on fuel consumption?
