Husqvarna 46" High-Lift Mulching Mower Blades, Pack of 2 — Forged Steel, Star-Mount (403107)

These two Husqvarna 46-inch high-lift mulching blades are forged replacement mower blades designed to restore cutting performance, improve clippings circulation for mulching, and fit star-mount Husqvarna riding mower decks.

Keeping your riding mower fitted with sharp, correctly angled blades is one of the simplest ways to improve cut quality and reduce time spent on repeat passes. These genuine Husqvarna blades are manufactured from hardened steel and engineered specifically for 46-inch decks that use a star-mount adapter, making them a direct fit for models that list OEM part number 403107.

How will these blades change the way my lawn mower cuts?

These high-lift mulching blades are shaped to pull grass clippings up into the airflow beneath the deck, where they are repeatedly sheared for finer mulch and a more uniform finish. The high-lift profile increases suction for improved bagging and consistent discharge when you switch modes.

• High-lift edge geometry increases airflow and clippings control.
• Mulching design chops clippings into finer pieces for faster decomposition.
• Balanced construction reduces vibration and promotes an even cut.

Are these blades easy to install and compatible with my mower?

Yes — each blade is a factory-style replacement intended for Husqvarna riding mowers that accept a star-mount adapter and the 46-inch blade length. Installation follows the same steps as the original blades and requires common hand tools.

• Direct OEM replacement for part number 403107.
• Star-mount fitment matches Husqvarna deck hubs for a secure attachment.
• Sold as a pack of two to replace both blades on a 46-inch deck or keep one as a spare.

What materials and manufacturing features improve durability?

Husqvarna blades are forged from hardened steel and precision-balanced to run smoothly for extended service life. The hardened edge resists dulling, and the finished surfaces are treated to lower noise and help sliding under the deck.

• Forged, hardened-steel construction for improved edge retention.
• Precision balancing reduces wear on spindles and bearings.
• Durable finish helps minimize noise and deck friction.

Will these blades support both mulching and bagging needs?

The 4-in-1 performance of these blades gives you flexibility: their high-lift profile produces the suction needed for effective bagging while the mulching contours keep clippings circulating for repeated cutting. That combination offers cleaner discharge and finer mulch when desired.

• High-lift suction for improved bagging and clip collection.
• Mulching edges keep clippings under the deck for repeated cutting.
• Clean discharge when used with bagging or side-discharge setups.

Who is this for: Owners of Husqvarna 46-inch riding mower decks (or compatible models using a star-mount adapter) who want a genuine OEM-quality replacement blade that restores factory cutting geometry, improves mulching results, and reduces vibration. This two-pack suits homeowners who maintain larger lawns and professionals who prefer keeping an immediate spare blade on hand for quick swapouts.
