Is your snowblower struggling to clear the white stuff, or worse, not working at all? One of the leading culprits is often a worn or broken snowblower drive belt. While replacing snowblower belts might sound complicated, it's actually a completely manageable maintenance task that can get your machine back to peak performance. In this guide, AZParts walk you through how to replace a snowblower belt safely and effectively, ensuring you're always ready to tackle any upcoming snowstorm.

1. What Does the Belt Do in a Snowblower?

The belts in your snowblower are crucial components, acting as the power links that transfer energy from the engine to the working parts of the machine. Essentially, they're what make your snowblower actually throw snow.

Snowblowers typically utilize two main types of belts, each with a specific job:

Auger Belts: These belts are responsible for transferring power from the engine to the auger (the rotating blades at the front of the snowblower). The auger is what gathers the snow and feeds it into the impeller.
Drive Belts: The drive belt, also known as the traction belt, transmits power from the engine to the wheels, allowing your snowblower to propel itself forward.

Belts are consumables, meaning they're designed to wear out over time. Several factors contribute to belt failure:

Heavy Use: Pushing through deep or icy snow puts significant stress on both auger and drive belts, leading to slipping, stretching, or snapping.
Wear and Tear: Regular operation causes friction and heat, which gradually weakens the belt material.
Age: Over time, rubber and other belt materials degrade, becoming brittle and prone to cracking or fraying.

2. When Should You Replace Your Snowblower Belt?

If you rely on a snowblower to clear your driveway and sidewalks during winter, keeping it well-maintained is key to making sure it runs smoothly all season long. One important part that needs regular attention is the snowblower belt .

Most factory-installed belts are built to last about five to seven years , depending on how often and how hard you use your machine. If you haven’t replaced the belt since you bought your snowblower and it’s been more than five years, now is a good time to check it. Even if the machine seems to be working fine, the belt may be worn down and could fail when you need it most.

Here are some signs that it might be time to replace your snowblower belt:

The auger or impeller is not spinning properly
You notice a rubber burning smell while using the machine
The snowblower has lost power or is not throwing snow as far as it used to
You see cracks, fraying, or a shiny glazed surface on the belt
The belt slips off or makes squealing noises during use

Even without visible damage, belts naturally wear out with time. Replacing them before they fail can help you avoid unexpected breakdowns during heavy snowfalls.

When buying a new belt, make sure to get the correct one for your specific model. Do not use regular automotive V-belts. They might look similar, but they are not strong enough for snowblower use and often break after just one season. It’s best to buy genuine factory belts either from your dealer or online. You will need your snowblower’s make and model number, as well as the engine brand and model number, to find the right match.

Replacing the belt yourself is something most people can do with basic tools, and it can save you money. Since the replacement steps can vary by model, always refer to your owner’s manual. If you don’t have one, you can usually download a copy from the manufacturer’s website.

3. Step-by-Step Instructions to Replace the Belt

3.1. Step 1: Turn Off and Prepare the Machine

Before you begin any maintenance, make sure your snowblower is completely powered off. Disconnect the spark plug wire to prevent accidental starting while you’re working on the machine. For extra safety, let the engine cool down completely if it was recently used.

Next, empty the gas tank. Tilting a snowblower with fuel inside can lead to dangerous spills or fumes. Once the machine is cool and the fuel is drained, move it to a clean, flat workspace with good lighting. Keep all your tools nearby for easy access. This preparation step is crucial for both your safety and the ease of the job.

3.2. Step 2: Remove the Belt Cover

Once the machine is safely prepped, begin by removing the belt cover (also known as the upper belt guard). This cover protects the drive system and needs to come off so you can inspect or replace the belts.

Use a socket wrench with a 12-inch extension bar to reach and loosen the bolts holding the cover in place. Carefully lift off the guard and set it aside along with the screws or bolts, keeping them organized for reassembly later.

With the cover off, you’ll have clear access to the top pulleys and belts. Take this opportunity to inspect the condition of the belts. If you notice any cracks, fraying, or glazing, it’s time for a replacement.

Now that the belt cover is removed and you have access to the pulleys, it’s time to take off the old belt.

Start by relieving the tension in the belt system. Depending on your snowblower model, this can be done by either loosening the tensioner pulley, removing the tension spring, or prying the idler roller back gently with a screwdriver.

Once the belt is no longer tight, carefully slide it off the pulleys. You may need to wiggle it slightly to work it free, especially if it has been in place for several years.

After removing the belt, take a few moments to inspect the pulleys. Clean off any dirt, debris, or belt residue using a dry cloth. This helps ensure smooth operation when the new belt is installed.

3.4. Step 4: Install the New Belt

With the old belt removed and the pulleys cleaned, you’re ready to install the new belt.

If your machine has a bottom access plate, now is the time to tilt the snowblower back (remember, the gas tank should be empty). Remove the plate to access the lower part of the pulley system if needed.

Carefully thread the new belt onto the pulleys, making sure it follows the same path as the old one. Double-check that the correct belt is going onto the correct pulley if your snowblower has multiple belts.

Once in place, reapply the tension by tightening the tensioner mechanism or reconnecting the spring. The belt should be snug but not overly tight, it should have a little flex, but not slip during use.

Finally, spin the pulleys by hand to make sure everything is aligned and moving smoothly before reassembling the belt cover.

3.5. Step 5: Reassemble and Test

Now that the new belt is installed, it’s time to put everything back together and make sure the machine is working properly.

Start by reattaching the bottom access plate (if you removed it earlier), then carefully lower the snowblower back to its normal position. Make sure all screws or bolts are securely tightened.

Next, reinstall the upper belt cover. Use your socket wrench to fasten it firmly in place, and double-check that no tools or parts have been left inside the housing.

Once everything is assembled, reconnect the spark plug wire. If you drained the gas tank earlier, refill it with fresh fuel.

Now, start the snowblower and let it run for a few minutes. Engage the auger and drive system to test the belt. It should move smoothly without slipping, squealing, or vibrating abnormally.

4. FAQs about Snowblower Belt Replacement

4.1. How often should you change snowblower belts?

Most snowblower belts last about 5 to 7 years , depending on how often you use your machine and how heavy the snow conditions are. If you notice performance issues, visible damage, or it's been over five years since you last replaced the belt, it’s a good idea to change it before the next snow season begins.

4.2. How do I know if my snowblower belt is bad?

There are several signs that your snowblower belt may be worn or damaged. Common symptoms include:

The auger or wheels are not engaging properly
A burning rubber smell while the machine is running
Squealing or grinding noises
Reduced snow throwing distance
Visible cracks, fraying, or shiny glazing on the belt

If you notice any of these signs, inspect the belt and replace it if needed.

4.3. How many belts does a snowblower have?

Most two-stage snow blowers have two belts — one for the auger and one for the drive system. Some single-stage models may only have one belt. Always refer to your owner’s manual to confirm the exact number and type of belts used in your specific model.

4.4. Is it worth fixing a snowblower?

In most cases, yes, it’s worth fixing a snowblower, especially if the issue is something simple like a worn belt, spark plug, or clogged chute. Replacing a belt is relatively low-cost and can significantly extend the life of your machine. However, if your snowblower is very old and requires multiple major repairs, you may want to compare the cost of fixing it versus investing in a new one.

Replacing your snowblower belt is a simple but important part of regular maintenance that ensures your machine runs smoothly and reliably all winter long. While belts are one of the most commonly replaced components, they’re just one piece of the puzzle.
