Additional information

This impeller, part number 684-05130-4028, spins behind the auger to move collected snow through the chute for discharge. Proper fit and alignment help maintain steady snow flow and consistent throwing performance.

If the snowblower clears poorly, snow backs up in the housing, or you hear unusual noises from the discharge area, the impeller may be bent, worn, or damaged. Reduced throwing distance or visible blade damage can also indicate an issue.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Impeller edges can be sharp; wear work gloves and support the impeller securely during removal and installation so it seats correctly and spins freely.
