This guy who lives in a cabin near are ski area has an annual "shed gap tradition" he has a bobcat with wheels on it to build a gap over a shed and we tow into it with 4 wheelers. It can move quite a bit of snow at once but then again Montana snow fairly light compared to most of the country. I will try to upload some pics from that later tonight or tomorrow.
This is the machine I have access to, its an ASV HD 4520
We used it for about 6 weeks in this kind of terrain;
It had absolutely no problem with any of the hills we went up, some of which were steep enough it hurt my ankles and knees to walk across. So I know it will do fine on the hills as long as we stay either straight or down on the hill. The machine itself ways about 6 tons but the surface pressure is only about 6psi... Could traction be a problem on snowy and icy hills?
