Available in 52-74-inch wide models with 30-inch cutting heights. Two stage design allows more throwing force with less horsepower than single stage models. In stage one, the auger bites into the snow and pulls it toward the fan. In stage two, the fan blades pick up the snow and blow it out the chute. Design improvements to the chute, fan blade, and working height result in snow being picked up better, moved quicker, and thrown farther.
