Understanding the difference between a single-stage snowblower and a dual-stage snowblower helps you to determine which snowblower type would be better suited to your needs. We’ve put together some quick facts about how each type of snowblower works.
A single-stage snowblower removes snow with one motion, using an impeller or auger. The auger is usually formed from two or more curved plastic paddles. These paddles pull the snow into the unit and then throw it out through the chute.
The snowblower sits low to the ground and removes snow down to the pavement. A single-stage snowblower is lightweight and easy to maneuver. It is best for clearing paved, moderate-sized driveways with snowfall depths of 10 to 12 inches.
A dual-stage snowblower removes snow with two components; a serrated-edge auger blade and a high-speed impeller. The auger cuts through the snow and feeds it to the impeller, which propels the snow away through the chute.
A dual-stage snowblower is slightly raised to allow for use on gravel driveways; as a result, it leaves a thin layer of snow behind. The dual-stage snowblower is larger than a single-stage, making it ideal for deeper snow and larger driveways. It is also self-propelled, making it perfect for use on steep areas.
You need a spark to fire up the engine of your snowblower, and that spark comes from a spark plug. You can replace one in minutes.
Replace the fuel line on your snowblower if it's cracked or damaged.
The shear pin breaks if you hit hard-packed snow, to protect the engine from damage. Your snowblower auger won't rotate until you fix it. You can replace it in about 10 minutes.
This video shows how to adjust a snowblower's auger control.
Learn how to tighten a snowblower drive control if the drive slips or doesn't engage, and how to loosen it if the snowblower creeps when you disengage the drive.
