Additional Information

MTD blade drive belt part number 490-501-M021 replaces part number 954-04077A. The belt turns the deck pulley to spin the mower blades. This belt maintains reliable blade rotation for consistent grass cutting performance.

If your lawn tractor is cutting unevenly, making unusual noises, or the blades stop spinning altogether, a worn or broken blade drive belt could be the cause. Replacing the belt restores smooth blade engagement and cutting ability.

Before replacing the belt, shut off the engine and disconnect the spark plug wire. Wear work gloves to protect your hands from sharp components. Use the proper wrench or socket set to access the deck and follow your model?s service manual for routing and tensioning the new belt correctly.

Regular inspection and timely replacement of the blade drive belt help prevent mower downtime and ensure a clean, even cut throughout the season.
