1. Check the auger drive belt: The auger drive belt is responsible for transmitting power from the engine to the auger. If the belt is broken, loose, or damaged, it will prevent the auger from engaging. To check the belt, open the snowblower's hood and look for the belt that runs from the engine to the auger assembly. If the belt is broken, replace it. If the belt is loose, tighten it.
2. Check the auger shear pins: The auger shear pins are designed to break if the auger encounters a hard object, preventing damage to the auger assembly. If a shear pin is broken, it will prevent the auger from engaging. To check the shear pins, look for the small pins that connect the auger to the auger drive shaft. If a shear pin is broken, replace it with a new one of the same size.
3. Check the auger drive clutch: The auger drive clutch is responsible for engaging and disengaging the auger. If the clutch is faulty, it will prevent the auger from engaging. To check the clutch, look for the part that connects the auger drive shaft to the engine. If the clutch is faulty, replace it.
4. Check the auger control cable: The auger control cable is responsible for transmitting the movement of the auger drive lever to the auger drive clutch. If the cable is broken, loose, or damaged, it will prevent the auger from engaging. To check the cable, look for the cable that runs from the auger drive lever to the auger drive clutch. If the cable is broken, replace it. If the cable is loose, tighten it.
5. Check the engine: If the engine is not running properly, it will not be able to provide enough power to engage the auger. Check the engine oil level, spark plug, and air filter. If any of these components are faulty, replace them.
If you have checked all of these things and the auger still does not engage, you should take your snowblower to a qualified repair technician.
