Additional Information

Mandrel assembly 918-04608A mounts to the mower deck and spins the blades for effective grass cutting. It replaces part numbers 618-0671, 918-0671, and 918-0671B. The included pulley transfers power from the deck belt to the mandrel shaft.

This part resolves common issues like blade stalling, vibration from the deck, or uneven mowing caused by worn or damaged mandrels. The housing?s mounting holes are not pre-threaded?use four self-tapping screws to ensure a secure fit.

Before beginning installation, disconnect the spark plug wire to prevent accidental engine start. Wear work gloves and use a torque wrench and nut driver to secure the bolts properly. Verifying correct alignment during installation helps maintain smooth blade operation and long-term mower performance.
