Additional Information

The MTD Lawn Tractor Mandrel and Pulley Assembly (part number 918-06976A) helps transfer power from the engine to the blades by supporting the pulley shaft and enabling smooth blade rotation. This complete assembly includes the mandrel shaft, bearings, housing, and pulley, offering a direct-fit replacement for worn or damaged deck components.

If your mower leaves an uneven cut or vibrates more than usual, the mandrel may be worn or misaligned. Swapping it out with this replacement can restore cutting consistency and reduce vibration. The housing has unthreaded mounting holes, so you'll need to order self-tapping bolt part number 710-1260A separately for proper installation.

Before starting the repair, disconnect the spark plug wire and wear work gloves to protect your hands. Use a wrench and screwdriver to remove the old assembly and secure the new one to the deck. Check your lawn tractor?s model number to confirm compatibility before ordering.

Keeping the mandrel and pulley in good condition helps extend the life of your mower and ensures reliable performance throughout the mowing season.
