• The size of your driveway and sidewalks: You'll want a snowblower that is capable of clearing the amount of snow you typically get in your area. If you have a large driveway or long sidewalks, you may want a larger snowblower with a wider clearing width.
• The type of snow you typically get: Wet, heavy snow will require a snowblower with a higher horsepower engine and a larger auger to move it efficiently. Light, powdery snow can be handled by a smaller machine.
• Your physical ability: If you have physical limitations or aren't able to push a heavy machine, you may want to consider a snowblower with electric start and self-propelled drive.
• Your budget: Snowblowers range in price from a few hundred dollars for a basic electric model to several thousand dollars for a top-of-the-line gas-powered machine. Determine your budget and look for a snowblower that meets your needs within that price range.
• Your storage space: Consider the size of the snowblower and where you will store it when it's not in use. If you have limited storage space, you may want to look for a smaller, more compact model.
