What about your belt and clutches? Heat buildup is no good. Most snowmobiles need a source of cooling as well, so if your plowing it, no good will come of that. To be able to get enough traction to plow a decent amount, you most likely need studs. Well, if your going across nice blacktop, your going to have to put down a new coat of concrete or pavement because it will all be torn to crap.
It said it had sheer away pins so it wouldn't break your a-arms. That means you wont be ripping your a-arms off and sliding to a stop, GREAT! You will be smashing over a metal snow plow causing you to go airborne and having the sled potentially land on you.
I could see where this is going. Major law suit.
