Why Snow Blowers Get Clogged
Snow blower clogging is a common issue, especially during heavy or wet snowfalls. Understanding the causes is the first step to fixing and preventing it.
Wet And Heavy Snow
Wet snow is sticky and dense. When your snow blower tries to move this type of snow, it can easily get stuck in the chute or auger. Even powerful machines struggle with wet snow, and clogging is almost guaranteed if you don’t take precautions.
Low Temperatures
Very cold weather makes snow lighter, but it also makes the snow blower parts colder. This can cause ice to form inside the chute and auger, leading to blockages. If the snow blower is stored outside, it’s more likely to freeze up before you even start.
Incorrect Machine Settings
Using the wrong speed or auger setting can make clogging worse. If you move too fast, the machine can’t clear the snow quickly enough. If you move too slow, snow packs down and becomes harder to clear.
Lack Of Maintenance
A dirty or poorly maintained snow blower is more likely to clog. Old oil, worn belts, and dull blades reduce efficiency. Sometimes, just a quick tune-up can solve many clogging issues.
Foreign Objects
Sticks, stones, and other debris hidden in the snow can jam your machine. Even small objects can block the chute and damage the auger.
Essential Tools And Materials For Unclogging
Before you start fixing a clogged snow blower, gather the right tools and materials. Using the proper equipment makes the job safer and easier.
- Snow blower clearing tool – Most snow blowers come with a plastic clearing stick. Never use your hands to clear a clog.
- Protective gloves – Thick gloves protect your hands from sharp edges and cold.
- WD-40 or silicone spray – Sprays help snow slide off chute surfaces and reduce sticking.
- Wrench set – For removing jammed auger parts or adjusting settings.
- Flashlight – Useful for spotting blockages in low light.
- Safety goggles – Protect your eyes from flying debris.
- Basic cleaning supplies – A rag and brush for removing ice and snow.
Having these items nearby means you can fix a clog quickly and safely.
Step-by-step Guide To Fixing Snow Blower Clogging
When your snow blower clogs, you need a clear process to get it working again. Follow these steps to resolve the issue efficiently.
1. Turn Off And Unplug
Always turn off your snow blower and remove the spark plug before trying to clear any blockage. This prevents accidental starts and serious injuries.
2. Locate The Clog
Look for packed snow in the chute, auger, or impeller area. Use a flashlight if needed. Most clogs happen in the discharge chute.
3. Use The Clearing Tool
Insert the plastic clearing tool into the chute and gently push out the blockage. Move the tool in a circular motion to break up packed snow. Never use your hands, even if the machine is off.
4. Remove Ice And Debris
If the blockage is made of ice or debris, chip away carefully with the clearing tool or a wooden stick. For stubborn ice, spray a little WD-40 or silicone lubricant to loosen it.
5. Inspect Auger And Impeller
Check if the auger blades or impeller are jammed. If you see a foreign object, use pliers or a wrench to remove it. Avoid forcing the blades, as this can damage them.
6. Restore Power And Test
Reconnect the spark plug and restart your snow blower. Run it at a low speed first to check if the blockage is gone. If the machine still clogs, repeat the process and check for underlying issues.
7. Prevent Future Clogs
After fixing the clog, spray the inside of the chute and auger with silicone spray. This makes snow less likely to stick and clog again.
Common Mistakes When Fixing Snow Blower Clogs
Many people make simple errors that can lead to injury or more frequent clogs. Avoid these mistakes for safer and smoother snow removal.
- Using bare hands to clear a blockage – Even with the machine off, blades can move unexpectedly.
- Ignoring the spark plug – Always disconnect to prevent accidental starts.
- Not checking for foreign objects – Small stones or sticks can cause repeated jams.
- Using metal tools – Metal can damage plastic or painted surfaces inside the chute.
- Restarting too soon – Test at low speed first to make sure the clog is gone.
- Forgetting to lubricate – Dry surfaces attract sticky snow and cause more clogs.
Preventive Maintenance For Snow Blower Clogging
Regular maintenance is the best way to prevent snow blower clogging. A well-maintained machine can handle tough conditions with fewer problems.
Lubricate Key Parts
Apply silicone spray or WD-40 to the chute, auger, and impeller before each use. This reduces sticking and makes snow slide out easily.
Check Belt Tension
Loose or worn belts slow down the auger and impeller, making clogging more likely. Inspect belts at the start of the season and replace if needed.
Sharpen Blades
Dull auger blades can’t cut through snow efficiently. Sharpen them or replace as necessary. Sharp blades are essential for handling icy or packed snow.
Clean After Each Use
Remove snow, ice, and debris after every session. This prevents buildup and keeps parts moving freely.
Store Indoors
If possible, store your snow blower in a garage or shed. Cold outdoor storage can lead to frozen parts and more clogging.
Inspect Chute Alignment
A bent or misaligned chute causes snow to build up and block the exit. Adjust the chute so it points directly away from the auger.
Comparing Types Of Snow Blowers: Clog Risk
Different snow blowers handle snow in different ways. Some types are more prone to clogging. Let’s compare the main types:
| Snow Blower Type | Clog Risk | Best Use |
|---|---|---|
| Single-stage | High | Light, fluffy snow |
| Two-stage | Medium | Moderate, wet, or heavy snow |
| Three-stage | Low | Large areas, deep snow |
Single-stage machines often clog with wet snow. Two-stage blowers are better for average conditions. Three-stage models have extra impellers that push snow out faster, so they rarely clog.
Troubleshooting Persistent Clogs
Sometimes, your snow blower keeps clogging even after cleaning and maintenance. Here’s how to troubleshoot deeper issues.
Check Engine Power
A weak engine can’t spin the auger fast enough. Check your oil level and fuel quality. If the engine struggles, consider a tune-up or professional service.
Inspect The Impeller
The impeller pushes snow out of the chute. If it’s damaged or slow, snow will pile up and cause clogs. Replace or repair as needed.
Look For Hidden Ice
Ice can form inside the chute overnight, especially if the machine is stored outside. Warm up the snow blower before use to melt hidden ice.
Adjust Auger Height
Lowering the auger can help with packed snow, but too low may cause it to jam. Adjust to match the snow depth.
Examine Chute Design
Some older or cheaper snow blowers have narrow chutes. These clog more easily. If possible, upgrade to a wider chute or use a snow blower with better design.
Test With Different Snow
If possible, try using your snow blower in light, dry snow. If it works well, the problem is probably wet snow or machine settings, not the blower itself.
Choosing The Right Snow Blower For Your Region
The risk of clogging depends on your local climate. Choosing the right machine can make a big difference.
| Region | Typical Snow | Recommended Snow Blower |
|---|---|---|
| Midwest | Heavy, wet | Two-stage or three-stage |
| Northeast | Mixed (light to heavy) | Two-stage |
| Mountain West | Powdery, deep | Three-stage |
| Pacific Northwest | Wet, slushy | Two-stage |
| Southern States | Occasional, light | Single-stage |
If you live in a region with frequent wet snow, invest in a two-stage or three-stage model to reduce clogging.
