I had a single stage "IH" snow thrower on my 125, heavy wet snow just plugged it up - never did work all that well. I just shoveled the light snow without bothering to start the old Cub. I eventually sold it because I didn't think it was worth the hassel.
A friend of mine had a "Craftsman" two stage snow blower that he modified to fit the front his Cub wide frame and it worked surprising well - a whole lot better than the IH thrower. I tried to buy it when he sold the Cub but the buyer wanted the little tractor and all the attachments.
