Snow Blower Runs But Won't Throw Snow: 4 Quick Fixes
The engine is purring at full throttle, but when you engage the auger drive handle, nothing happens or snow barely dribbles out of the chute. Here is how to diagnose the breakdown.
With the engine off, try to spin the spiral auger blades by hand. If an auger spins freely around the shaft without turning the center gearbox, the shear pin is snapped. Replace with an OEM shear bolt and locknut.
Under the black plastic belt cover between engine and auger housing sits the auger drive belt. If the belt is glazed, stretched, or thrown off the pulley idler, the impeller will not spin under snow load.
The cable connecting your handlebar lever to the belt tensioner pulley can stretch over time. Adjust the barrel nut on the cable to increase tension so the idler pulley fully pinches the belt against the drive pulley.
If you park a warm snow blower outside after use, melted snow drips into the impeller drum and refreezes solid overnight. Use a wooden stick to check if the impeller is frozen to the steel drum before engaging the clutch.
