Cub Cadet Mulching Blade

This blade is specifically engineered for Cub Cadet 21-inch decks. While some mower parts are interchangeable, we strongly recommend sticking to the manufacturer's specified parts to ensure proper fitment, safety, and optimal cutting performance.

A mulching blade features a curved design and specialized cutting edges that create extra airflow under the deck. This lifts the grass clippings and recuts them into fine particles, which then settle into the soil to act as a natural fertilizer.

Generally, no. However, for the best results, ensure your mower's discharge chute is closed or blocked off with a mulching plug. This keeps the clippings circulating under the deck long enough for the blade to shred them properly.

You should inspect your blade for nicks, dull edges, or bending at the start of every season or after hitting a hard object. If the blade is damaged or the cutting edge is rounded and no longer sharp, it is time for a replacement to ensure a clean, healthy cut for your grass.

No, this package contains a single 21-inch mulching blade. If your mower requires multiple blades, you will need to purchase the appropriate quantity separately.
