Additional Information

The Husqvarna lawn mower mulching blade (part number 159267) replaces 187183, 33273, 33364, and 532159267. Its contoured design enhances mulching performance by swirling clippings inside the deck and recutting them into finer pieces. This process helps prevent clumping and promotes healthy lawn growth.

Symptoms that indicate the need for blade replacement include clumps of grass left behind, reduced mulching efficiency, or dull cutting performance.

Before installing, disconnect the spark plug wire to prevent accidental starting. Wear work gloves when handling blades, and use a socket wrench and torque wrench to secure the new blade properly. For step-by-step instructions, refer to the How to replace a lawn mower blade repair guide.
