Bought this Old Craftsman Snow blower for $15, never really got to use it on much because we didnt have any good snow fall, but in december we had 22 inches of snow fall from the 18th to 20th, days after we had warm weather rapidly melting much and making it very heavy, in which i brought out the old Snow blower which moves wet snow very well, Enjoy!
