Additional Information

The lawn tractor mandrel and pulley assembly (part number 918-06981) helps the mower blade spin by supporting the pulley shaft on the deck. If your mower cuts unevenly, vibrates more than usual, or makes grinding noises, this part could be worn out or damaged.

Replacing the mandrel and pulley assembly restores smooth operation and cutting performance. Before you start, disconnect the spark plug wire and wear work gloves to protect your hands from sharp edges. Use basic hand tools to remove the old assembly and install the new one securely.

This is a manageable DIY repair for most lawn tractor owners with a little mechanical know-how. Always check your service manual for model-specific steps and torque specs.
