Husqvarna Riding Mower Blades

These blades are designed specifically for 48-inch riding mower decks. To ensure a perfect fit, verify that your mower requires OEM part number 532-173921, which is the standard reference for this specific blade set.

Mulching blades feature a specialized shape that creates extra lift and airflow under the deck. This action chops grass clippings into fine particles, which then settle into the soil to act as a natural, nutrient-rich fertilizer for your lawn.

Yes, this package contains three blades, which is the complete set required for a standard 48-inch riding mower deck. Replacing all three at once ensures your mower maintains an even, balanced cut.

For optimal cutting performance and lawn health, you should inspect your blades at the start of every season. If the edges are dull, chipped, or bent, they should be replaced immediately to prevent tearing the grass, which can leave your lawn susceptible to disease.

While these are engineered specifically for mulching, they can be used with side-discharge setups. However, you may notice that the clippings are smaller and more finely distributed than they would be with standard high-lift blades.
