Know before you buy
This blade is designed specifically for 21-inch Husqvarna decks. To ensure a perfect fit, verify that your current blade matches OEM part number 581694101 or the replaced numbers 532406712 and 594893001.
The 3-in-1 design allows you to switch between bagging, mulching, and side discharge without needing to swap blades. It is engineered to provide consistent airflow and cutting efficiency regardless of which discharge method you choose.
This is a genuine Husqvarna replacement part. Using OEM components ensures the blade meets the exact material and balance specifications required for your specific mower model.
This blade is intended for standard-duty residential use. While it is highly durable for typical lawn maintenance, it is not designed for clearing heavy brush or commercial-grade, high-frequency cutting.
Installation requires standard tools, typically a socket wrench and a way to secure the blade from spinning while you loosen the mounting bolt. Always disconnect your spark plug wire before beginning the installation for safety.
