What is a TWO-STAGE SNOW BLOWERS
Briggs & Stratton® Two-stage, or Dual-stage, Snow Blowers have a self-propelled transmission with forward and reverse speeds that propel the unit in order to assist the user.
Different than a single-stage, there are two distinct stages of snow removal, thus the dual-stage name. In the first stage, the auger collects the snow and transfers it to the center of the machine and back into the impeller, which then throws it up and out of the chute. The auger and impeller, combined with the power of the engine, remove the snow faster by chewing up snow and ice, and then throwing it through the chute.
Two-stage snow blowers are great for handling all types of snow on any surface. Two-stage snow blowers may be an ideal choice for those with gravel driveways, as they will not clean down to the ground like a single-stage snow blower.
