Looking at upgrading my snowblower. I've got a Honda HS520 that isn't really cutting it. Just inherited a mid 90's snapper medium frame, but the engine on it has some major issues. So I found this. Don't know anything about it, owner wants $400. Any advice would be appreciated. I've been looking on these forums for good recommendations, and it seems ariens and toro are the sure bets. Let me know what you think of this one.
