Two-stage auger and cast iron gearbox
   
   
  The low-speed auger picks up snow and moves it toward the center of the machine into the high-speed rotor where it is blown out of the discharge chute.
   
  A cast-iron gearbox provides speed reduction for the auger and is protected by shear bolts for each auger half.
   
  Two-stage snow blowers are more effective than single-stage snow throwers when operating in deep snow as the low-speed auger is used to size crusted material. They also provide consistent snow placement in variable snow conditions because the high-speed rotor gives the discharged snow consistent velocity-even in very light clean-up volumes.
  
   
    
    Durable, second-stage blower fan
   
   
    
    Cast-iron gearbox
   
   
  The second-stage blower fan is formed from the same durable and rust-resistant, ultra-high molecular weight (UHMW) polyethylene material proven in the Power Flow™ blower fan for durability and long life.
   
  The durable fan material has the same cold-weather characteristics as snowmobile track rollers and will not bend and cause the fan to get out of balance.
   
  A single-belt drive system coupled to a cast-iron gearbox with a horizontal sheave minimizes belt angles and twists for superior reliability and durability.
