Snowblowers are indispensable tools for many people during the winter months, helping to clear driveways, sidewalks, and pathways of snow. However, a common issue that users face is the wheels of the snowblower stopping when they hit snow. This can be frustrating and disrupt the process of snow removal. Understanding the reasons behind this issue can help in troubleshooting and ensuring the snowblower operates smoothly. In this article, we will delve into the various factors that can cause snowblower wheels to stop turning when they encounter snow, along with solutions to these problems.
1. Drive Belt Issues
One of the primary reasons snowblower wheels stop turning is due to problems with the drive belt. The drive belt is responsible for transferring power from the engine to the wheels. Over time, the belt can become worn, stretched, or even break. When the belt is not functioning properly, it cannot efficiently transmit power, causing the wheels to stop.
Solution: Regularly inspect the drive belt for signs of wear and tear. If the belt appears worn, cracked, or stretched, replace it immediately. It’s also advisable to keep a spare drive belt on hand during the winter months to minimize downtime.
2. Shear Pins and Bolts
Shear pins and bolts are designed to break under excessive stress to protect the snowblower’s auger and gear case. If the shear pins or bolts break, the wheels can stop turning even though the engine is running.
Solution: Check the shear pins and bolts regularly and replace any that are broken. Always use the manufacturer’s recommended shear pins and bolts to ensure proper operation and protection.
3. Clogged Auger or Impeller
Snowblowers can get clogged with heavy, wet snow, which can impede the movement of the auger and impeller. When these components are clogged, the snowblower can struggle to move, and the wheels may stop turning.
Solution: After every use, clear any snow and debris from the auger and impeller. During operation, take breaks to check and clear any buildup of snow. Consider using a non-stick spray designed for snowblowers to reduce the likelihood of clogging.
4. Traction Issues
Snowblowers rely on traction to move efficiently through the snow. If the wheels lack traction, they may spin or stop moving altogether, especially in deep or icy conditions. This can be exacerbated by worn-out tires or insufficient weight on the snowblower.
Solution: Ensure that the snowblower tires are in good condition with adequate tread. In icy conditions, consider using tire chains to improve traction. Adding weight to the snowblower can also help maintain better contact with the ground and improve movement.
5. Transmission Problems
The transmission in a snowblower is responsible for controlling the speed and direction of the wheels. Transmission problems, such as worn gears or low transmission fluid, can cause the wheels to stop turning.
Solution: Regularly check the transmission fluid levels and top up if necessary. Inspect the transmission for signs of wear or damage and consult a professional for repairs if needed.
6. Incorrect Speed Setting
Operating the snowblower at an incorrect speed can cause the wheels to stop turning. Moving too quickly through heavy snow can overload the snowblower, causing it to bog down and the wheels to stop.
Solution: Adjust the speed settings on your snowblower to match the conditions. For heavy or deep snow, use a lower speed setting to allow the machine to process the snow more effectively.
7. Engine Power Issues
If the engine is not running at full power, it may not be able to provide enough power to the wheels, causing them to stop turning. This can be due to a variety of issues, such as a clogged air filter, dirty spark plug, or fuel problems.
Solution: Perform regular engine maintenance, including checking and replacing the air filter, spark plug, and ensuring the fuel is clean and fresh. Follow the manufacturer’s maintenance schedule to keep the engine running smoothly.
8. User Technique
The technique used by the operator can also impact the performance of the snowblower. Pushing the snowblower too aggressively or at an improper angle can cause the wheels to stop.
Solution: Operate the snowblower at a steady pace and avoid forcing it through the snow. Ensure the snowblower is level and maintain a consistent angle to optimize performance.
9. Environmental Factors
External environmental factors such as extremely deep snow, ice, or slush can create conditions where the snowblower struggles to move, leading to the wheels stopping.
Solution: For extremely deep snow, consider making multiple passes to gradually reduce the depth. For icy conditions, pre-treat the area with ice melt to improve traction and reduce the workload on the snowblower.
10. Mechanical Wear and Tear
Like any machine, snowblowers experience wear and tear over time. Components such as bearings, bushings, and axles can wear out, leading to reduced performance and wheels stopping.
Solution: Regularly inspect all moving parts for signs of wear and replace any worn components. Lubricate bearings and bushings as per the manufacturer’s recommendations to ensure smooth operation.
Preventative Maintenance Tips
Regular Inspection: Frequently inspect all parts of the snowblower, including belts, shear pins, tires, and the transmission. Look for signs of wear and replace parts as necessary.
Lubrication: Keep all moving parts well-lubricated to reduce friction and wear. Use appropriate lubricants recommended by the manufacturer.
Engine Maintenance: Follow the manufacturer’s guidelines for engine maintenance, including oil changes, air filter replacement, and spark plug checks.
Cleaning: After each use, clean the snowblower thoroughly to remove snow, ice, and debris. This prevents buildup that can cause clogs and other issues.
Storage: Store the snowblower in a dry, protected area when not in use. Proper storage prevents rust and damage from environmental exposure.
