Function

• A snow blower effectively pulls in snow, as it is being moved across the ground, and blows it out to the side to free up walkways or concrete yard areas. Many snow blower types use engines with varying capacities to complete these jobs.
  
  

Capacity

• The engine capacity references the volume that all the engine cylinders combined possess. Typically, the higher the capacity, the more power an engine has to provide. For Toro single-stage snow blowers, their engine capacities range from 87 to 163 cubic centimeters. In contrast, their two stage blowers offer ranges from 205 to 342 cubic centimeters.
  
  

Alternative

• Toro also offers electric snow blowers. Since they are electrical, they have electrically-driven motors that propel them forward, as opposed to a combustion engine.
