Additional Information

This left-side auger, part number 684-04151-0637, uses rotating blades to gather snow and feed it toward the impeller so it can be discharged through the chute during operation.

If the auger blades are bent, cracked, worn or no longer rotate smoothly, replacing the auger helps restore proper snow-moving performance and prevents drivetrain damage.

Disconnect the spark plug wire before beginning the repair. Wear work gloves when handling sharp auger edges and working inside the auger housing.
