Most snowblowers, or snow throwers as they are sometimes referred to, are classified as either single-stage or dual-stage. Single-stage models use an auger to both collect and throw the snow, working best on snow that is six inches deep or less. Dual-stage snowblowers will use an auger to collect the snow and an impeller to throw it. These models can handle snow as deep as one foot or more depending on the size of the auger housing. A single-stage snowblower will have only one drive pulley attached to the crankshaft. To engage the auger, a spring-loaded idler pulley and belt are used. When the bail arm is engaged, the idler pulley tightens the auger drive belt around the drive pulley causing the auger to rotate.
