Additional Information

Blade drive belt 954-05025A transfers power from the engine to the mower deck blades, helping your lawn tractor deliver a clean, even cut. It loops around a series of pulleys to engage the blades as the engine runs, making it a key part of the mowing system.

If your lawn tractor leaves patches of uncut grass, or if the blades hesitate or fail to spin at full speed, a worn or stretched belt may be the cause. Replacing the belt restores proper blade engagement and improves cutting performance.

Disconnect the spark plug wire before beginning repairs. Raise the mower deck safely and wear work gloves to protect your hands while working near sharp blades and metal edges. Inspect pulleys for wear during replacement to avoid premature belt failure.
