Additional information

This impeller, part number 684-0069, spins behind the auger to move collected snow through the chute for discharge. Proper impeller fit and alignment help maintain steady throwing distance and consistent snow flow.

If the snowblower clears poorly, snow backs up in the housing, or you hear unusual noise from the discharge area, the impeller may be bent, worn, or damaged. Reduced throwing performance 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 assembly securely during removal and installation so it seats correctly and spins freely.
