As the last leaves fall and the air grows crisp, homeowners begin to anticipate the inevitable arrival of winter's icy grip. While the first snowfall can be exciting, it's crucial to ensure your snow-clearing equipment is ready to tackle the challenge. Neglecting your snowblower during the off-season can lead to costly repairs and frustrating delays when you need it most. This guide will walk you through the essential steps to properly winterize your snowblower, ensuring it remains in peak condition for the upcoming season.
Understanding the importance of proper maintenance can save you time, money, and a great deal of hassle. By investing a little effort now, you can extend the lifespan of your snowblower, improve its performance, and guarantee it starts reliably when the snow begins to fly. This article will cover everything from fuel stabilization and oil changes to spark plug replacement and storage tips, providing you with the knowledge to confidently prepare your snowblower for its winter slumber.
The Crucial First Step: Fuel System Care
The most critical aspect of winterizing a snowblower is addressing its fuel system. Gasoline, especially when left in the tank for extended periods, can degrade, leading to gumming and varnish formation. This residue can clog fuel lines, the carburetor, and the fuel filter, making it difficult or impossible for the engine to start in the fall. Therefore, the first and most important step is to stabilize the fuel.
To stabilize the fuel, you have a couple of options. The most common method is to add a fuel stabilizer directly to the gas tank when it's nearly empty. Follow the product's instructions carefully, ensuring you add the correct ratio of stabilizer to fuel. Once added, run the engine for about 5 to 10 minutes. This allows the stabilized fuel to circulate throughout the entire fuel system, including the carburetor, ensuring all components are protected from degradation.
Alternatively, if you prefer to drain the fuel system entirely, you can do so by running the engine until it completely exhausts the fuel in the tank. This method is more labor-intensive but guarantees no old fuel remains. If you choose to drain it, ensure you do so in a well-ventilated area and dispose of any residual fuel responsibly according to local regulations.
Engine Oil and Spark Plug Maintenance
Just as a car needs regular oil changes, your snowblower's engine requires fresh oil to operate smoothly and prevent internal wear. Before storing your snowblower for the winter, it's an excellent time to change the engine oil. This removes any contaminants or moisture that may have accumulated during the previous season's use.
To change the oil, locate the drain plug on the engine's oil pan. Place a suitable container underneath to catch the old oil. Remove the drain plug and allow the oil to drain completely. Once drained, replace the drain plug and refill the engine with the correct type and amount of fresh oil as specified in your snowblower's owner's manual. Using the wrong type of oil can lead to engine damage.
While you're attending to the engine, it's also wise to inspect and potentially replace the spark plug. A fouled or worn spark plug can cause hard starting and poor engine performance. Remove the old spark plug, check its condition, and if it appears worn, dirty, or damaged, replace it with a new one. Ensure the gap on the new spark plug is set according to your manual's specifications before installation.
Cleaning and Lubrication for Longevity
A thorough cleaning of your snowblower is essential before storing it. Remove any caked-on snow, ice, mud, and debris from the auger, impeller, housing, and wheels. Use a stiff brush, a scraper, and a damp cloth for this task. Pay close attention to the auger and impeller areas, as packed snow and ice can cause rust and impede their movement.
Once clean, it's time for lubrication. Apply a light coat of oil or a silicone spray to metal parts that are prone to rust, such as the auger shaft, shear bolts, and the discharge chute. For moving parts like the control cables and pivot points, use a grease or a multi-purpose lubricant. This not only prevents rust but also ensures these components move freely when you need them next season.
Don't forget to check the tires. If they are underinflated, add air to the recommended pressure. Inspect them for any cracks or damage that might require attention before the next snowfall. A well-cleaned and lubricated machine is less likely to suffer from corrosion and mechanical issues during its downtime.
Battery Care and Storage Considerations
If your snowblower has an electric start feature, the battery requires special attention during winterization. Batteries can lose their charge over time, and extreme cold can further degrade their performance. The best practice is to remove the battery from the snowblower before storing it.
Once removed, clean the battery terminals to ensure good contact. Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures. Ideally, you should connect it to a trickle charger or a battery tender periodically throughout the winter to maintain its charge. This prevents deep discharge, which can permanently damage the battery.
When storing the snowblower itself, choose a dry, protected location. A garage, shed, or covered patio is suitable. Avoid storing it directly on the ground, as this can lead to moisture absorption and rust. Elevating it slightly on blocks of wood or a pallet can help keep it dry and protected from the elements.
Pre-Season Checks and Final Touches
As the winter season approaches, it's time to bring your snowblower out of storage and perform some final checks. Reinstall the battery if you removed it, ensuring it's securely connected. Check the fuel level and add fresh gasoline if necessary, remembering to use a stabilizer for the initial fill.
Inspect all the safety features, including the shear bolts, discharge chute controls, and any safety interlocks. Ensure they are functioning correctly. Test the engine by starting it up and letting it run for a few minutes. Listen for any unusual noises or vibrations. If you encounter any issues, consult your owner's manual or a qualified service technician.
A final visual inspection of the entire machine can reveal any overlooked issues. Look for loose parts, worn components, or signs of damage. Addressing these minor concerns before the first major snowfall will save you from potential breakdowns and ensure you're ready to clear your driveway efficiently.

Frequently Asked Questions
How often should I change the oil in my snowblower?
For most snowblowers, changing the oil annually is sufficient, especially before winter storage. However, if you use your snowblower extensively or in very dusty conditions, you might consider changing it more frequently, as recommended in your owner's manual.
What kind of fuel stabilizer should I use?
Look for a quality fuel stabilizer specifically designed for gasoline engines. Brands like STA-BIL, Sea Foam, or PRI-G are popular and effective. Always follow the manufacturer's instructions for the correct dosage.
Can I leave gasoline in my snowblower over the summer?
It is strongly discouraged to leave gasoline in your snowblower over the summer. Gasoline degrades relatively quickly, and the resulting varnish and gum can cause significant damage to the fuel system. It's best to either drain the fuel tank completely or use a fuel stabilizer if you plan to store it for an extended period.
What are shear bolts and why are they important?
Shear bolts are designed to break or "shear" under excessive stress, such as when the auger hits a hard object like a rock or a thick root. This sacrificial component protects the more expensive parts of the auger and transmission from damage. Always replace sheared bolts with the correct type and size specified by the manufacturer.
My snowblower is hard to start after storage. What could be the problem?
Hard starting after storage is often due to issues with the fuel system. The most common culprits are stale fuel, a clogged carburetor, or a dirty fuel filter. Ensure you used a fuel stabilizer, and if the problem persists, you may need to clean the carburetor or replace the fuel filter. A weak spark plug can also be a factor.
