Ariens snowblowers are built to handle deep snow and tough Canadian winters, but even the most dependable machines can run into issues over time. When something goes wrong, it is often tied to a few common components that wear out or need adjustment.
Knowing what to look for and how to fix it can save you from being stuck in the middle of a storm with a machine that will not cooperate.
Snowblower Won’t Start
A snowblower that will not start is one of the most common frustrations, especially after sitting idle between storms or over the off-season.
Start by checking the fuel. Old fuel is a frequent cause of starting issues, particularly in cold weather. Replacing it with fresh gas often solves the problem. If it still will not start, inspect the spark plug. A worn or fouled plug can prevent ignition and is an easy fix.
Engine Starts but Runs Rough
If your snowblower starts but does not run smoothly, airflow or fuel delivery is usually the issue.
A dirty air filter can restrict airflow and cause the engine to sputter. Cleaning or replacing it can restore performance. If the problem continues, the carburetor may be partially clogged and need cleaning.
Auger Not Turning
If the engine is running but the auger is not moving, the issue is often related to shear pins or belts.
Shear pins are designed to break under stress to protect the gearbox. If they have snapped, the auger will stop turning. Replacing them is quick and inexpensive. If the pins are intact, the auger belt may be worn or broken and will need replacement.
Snow Not Throwing Far Enough
Reduced throwing distance is usually a sign of a worn impeller or slipping belt.
Check the auger and impeller for buildup or damage. Ice and packed snow can limit performance, so clearing any obstruction is a good first step. If the problem persists, inspect the belts for wear or loss of tension.
Drive System Not Engaging
If your snowblower is not moving forward or backward, the drive system likely needs attention.
A worn or stretched drive belt is a common cause. Replacing it often restores proper movement. It is also worth checking the friction wheel, as wear here can reduce traction and prevent the machine from moving as it should.
Chute Won’t Turn or Adjust
If the chute becomes difficult to turn or will not stay in position, the issue may be related to frozen components, worn gears, or lack of lubrication.
Start by checking for ice buildup and clearing it away. Applying lubricant to the chute mechanism can restore smooth movement. If the problem continues, worn gears or control components may need replacement.
Excessive Vibration
Unusual vibration during operation should not be ignored. It can be caused by loose hardware, damaged auger components, or worn internal parts.
Inspect the machine for loose bolts and tighten as needed. If vibration continues, check the auger and impeller for damage or imbalance. Addressing this early helps prevent further wear.
Snowblower Stalls Under Load
If your snowblower runs fine until it hits heavy snow, then stalls, the issue is often related to fuel delivery or engine performance.
A clogged fuel filter or carburetor can restrict fuel flow under load. Replacing the filter and ensuring clean fuel is being used can help. If needed, cleaning the carburetor may restore full power.
