The engine speed on a blower this size should be over thirty-six hundred RPM with seven-point nine-five foot-pounds of torque.Īs a smaller snowblower, you can expect this size to sport a single augur.
Your 208cc snowblower should run around five and a half to seven horsepower. For example, for a 150 CC engine, you would take 150 divided by 15, which equals 10 HP. The general rule is for every 15 CC, there is 1 HP. Moreover, the self-propelled speeds help reduce fatigue and make it easier for you.Ĭalculate the horsepower or CC by multiplying or dividing by 15. You can expect models of this size to have a variety of speeds.įor example, the Craftsman 21″ Snowblower has six forward and two reverse speeds to suit any user or conditions. Typically a 179cc snowblower is five to six horsepower. However, you can’t use these small models on gravel or concrete. In that case, it will handle roughly eight inches to a foot of snow, but you don’t want to test it against deeper piles of powder. Meanwhile, at twenty-six inches wide, it’s passable but not great.Īt this size, you probably have a single stage snowblower. If your model is twenty-one inches high or less, and the width is no more than two feet, then you have enough power. Is 8 HP Good For SnowblowerĮight horsepower is an excellent rating for a small to medium residential snowblower. At 22 inches wide, some models only come with five to six hp. You can find snowblowers that have truly minimal horsepower. However, you may want to scale up unless you deal with infrequent and shallow snow. A better minimum is around a half hp an inch. The minimum horsepower you need for a snowblower is around 0.3 hp per inch wide. What Is The Minimum HP Needed For Snowblower Frequency of Use – If you live in an area with short winters and infrequent snow, it’s a different level of need from a place in the far northern hemisphere where it snows a hundred days a year or more.Snow Depth – Do you live in an area that gets a couple of inches, or are you clearing the only access to a remote cabin in a damp area of Alaska?.According to AGreenHand, the stages also indicate how many augers the blower uses.
Double-stage blowers handle larger areas and slight inclines, and triples cover a more extensive, less even area.
