![]() ![]() Overall, they are constructed with lighter-gauge steel. These correspond closely with their Murray counterparts, also offered under the Briggs and Stratton brand, Altogether, these are less durable with smaller and lighter components, including the augurs (by 2-inches), augur gearbox, impeller, and snow box. Lastly among Simplicity's offerings, the Medium-Duty snow blowers are entirely manufactured by Murray. These currently employ engines that are reasonably powerful and roughly 50cc smaller than those found in the Signature Pro modelsThis is a good quality choice that would rank closely with our other two brand choices cited below. Referring to the second photo below, it is apparent that these use a traction drive (drive box with handlebars and controls) manufactured by Murray combined with the Simplicity Signature Pro snow box (front end with chute, impeller, augurs, and augur gearcase). Simplicity's Heavy-Duty snow blowers are also a good choice and would rank closely with our other two brands' offerings outlined below. This kind of quality runs through the entire snow blower from the heavy ribbon-steel augurs and 4-blade impeller to the heavy-duty traction drive. Referring to the first photo below, notice the heavy-gauge steel construction of the augur box and impeller barrel, along with the cast-iron handles, and C-channel steel handlebar supports. Their construction and performance are unsurpassed from every vantage point. These are true commercial-grade machines that are rather expensive. The first is Simplicity's Signature Pro Professional Series of snow blowers. Barring very old equipment, really there are only 3 brands of snow blowers that have sufficient quality and durability to get our recommendation. With this information in hand, here is our assessment. Since Overhead Valve (OHV) engines put out more power per cc, one can subtract 40 cc to 50 cc from these figures to arrive at corresponding power values. For flat-head engines, 300 cc to 320 cc equates to about 7 to 8 HP, 340 cc to 360 cc equates to 9 to 10 HP, and 380 cc to 400 cc equates to 11 to 12 HP. I generally refer to engine size as a guide. Now, because many brands, in particular Sears, overstated power on their products, and because torque, which closely relates to engine size, is a better indicator of power, the FTC now requires that makers of snow blowers and riding mowers quote torque and engine size instead of arbitrary HP ratings. So, adequate combinations include 24- to 26-inches and 7 to 8 HP, 27- to 30-inches and 9 to 10 HP, and 32- to 36-inches and 11 to 12 HP. As the augur box (sometimes called the snow box) widens, the engine capacity should rise accordingly. The ideal ratio of power to intake size on a full-sized snow blower with a 20- to 21-inch intake height is 8 HP to 24-inches in width. ![]() First, let's discuss power in relation to intake size. ![]()
