Maxpower 48-inch Mulching Blades 3-Blade Commercial Set for Craftsman Husqvarna Poulan — Made in USA, Factory-Sharpened

This replacement kit includes three heavy-duty mulching blades engineered to restore or improve the mulching performance of 48-inch lawn mower decks. Each blade is 16-5/8" long, 2-1/2" wide and features a five-point star center hole to match common OEM hubs. Built to meet or exceed original equipment specifications, the blades are factory sharpened and powder coated for corrosion protection; the coating will wear off on first use to reveal the precision edge beneath.

Will these blades fit my mower?

These blades are designed to replace specific OEM part numbers and fit most 48" decks from several popular brands. Before purchasing, compare the OEM numbers and the blade dimensions to your current blades to ensure compatibility.

• Blade length 16-5/8" and width 2-1/2"
• Five-point star center hole matches common 48" deck hubs

How do these mulching blades improve cutting and clippings?

Commercial mulching blades increase the cutting surface area and have sharpened teeth to finely chop grass and distribute clippings evenly. Their centrifugal air-lift design helps keep clippings circulating under the deck so material is chopped repeatedly for smaller mulch particles.

• Greater cutting surface for enhanced mulching performance
• Sharpened cutting teeth provide a cleaner, more uniform cut
• Centrifugal air lift design promotes even chopping distribution
• Powder-coated finish protects during storage and transport

How long do the blades last and how should I care for them?

Blade life depends on terrain, contact with debris, and maintenance frequency. Inspect blades regularly for nicks or bends, and sharpen or replace them if performance declines; the factory edge is ready to use after the powder coat wears off.

• Factory-sharpened; powder coat peels on first cut to reveal edge
• Avoid striking rocks and hard objects to extend life
• Check balance and sharpen only when needed to maintain performance
• Replace in matched sets for consistent deck balance and cut quality
