The field of hand surgery deals with both the surgical and nonsurgical treatment of conditions and problems that may take place in the hand or upper extremity (from the tip of the hand to the top of the arm).
Snow blowers come in a great variety of sizes, horsepowers, and stages. Therefore, the price range is quite large. Snow blowers can cost anywhere from $200 to $1000. For example, the Greenworks 26032 is a lower-end electric snow blower that is 20 inches wide and will cost about $200. The Murray 1695537 is gas powered, wider, and will cost around $400.
Snow blowers can generally be divided into two classes: single-stage and two-stage. On a single-stage snow blower, the auger (the paddle mechanism visible from the front) pulls snow into the machine and directs it out of a discharge chute. The auger contacts the ground, making single-stage snow blowers unsuitable for use on unpaved surfaces. On a two-stage snow blower, the auger pulls snow into the machine and feeds it into a high-speed impeller, which in turn directs it out of a discharge chute. Two-stage snow blowers can generally handle deeper snow depths than single-stage ones, and because their augers don't touch the ground, they can be used on unpaved surfaces
