Additional Information

Mulching blade 532406713 replaces part numbers 406713, 5324067-13, and 584660302. Its contoured shape helps improve airflow in the mower deck, allowing the blade to cut clippings into smaller pieces. This reduces the need for bagging and helps return nutrients to the soil.

If your current blade is worn or dull, replacing it can improve cut quality and mulching performance. Symptoms like uneven cuts or clumping may indicate the blade needs replacement.

Before installation, disconnect the spark plug and secure the mower on a level surface. Use a socket wrench to remove the old blade and install the new one. Always wear work gloves to protect your hands. For full instructions, see our How to replace a lawn mower blade repair guide with video.
