Additional Information

The Husqvarna 21-Inch Deck Blade (part number 532180459) maintains the cutting efficiency of your lawn mower by delivering a clean, even cut. It replaces part numbers 180459 and 5321804-59.

If your mower leaves patches of uncut grass or produces uneven cuts, the blade may need to be replaced. A dull or damaged blade can also strain the engine and reduce mowing performance.

Before replacing the blade, turn off the mower and disconnect the spark plug wire to prevent accidental starting. Wear work gloves to protect your hands from sharp edges. Use a socket wrench to remove the bolt securing the old blade, align the new blade, and tighten it securely with a torque wrench to the manufacturer's specifications. For detailed steps, refer to the How to Replace a Lawn Mower Blade guide.

Always handle mower blades carefully and follow all safety procedures during installation to avoid injury and ensure proper performance.

After 18 years of use I was surprised to see how much material was gone from the original blade. This new blade definitely performs better.

Standard Blade

After looking on other sites for this blade I went to Sears Direct. They call this a 21 inch blade but it doesn't measure that longer it is shorter than that, plus the hole in the center is larger than most.

Very easy to install, world of difference in mowin
July 16, 2018|hey-mike, Chicago, IL

It took longer to uninstall the old blade than it took to install the new blade (rust, build-up, etc). The new blade was a piece of cake to install, and it's made a world of difference in how the mower performs. I definitely recommend getting new bolts to go with it.
