The Ariens 36” Snow Blower Head (Model 851002) is an all-steel two-stage snow throwing attachment designed for the Ariens Mammoth 850 snow removal vehicle. It clears a 36-inch working width and uses an auger/impeller system to break up snow and throw it through a directional discharge chute for efficient snow removal on sidewalks, walkways, and tight areas.
