Maxpower Commercial Mulching Blade 22 in (331749XB) for Craftsman/Husqvarna — USA-made, 5-point star fit

MaxPower 331749XB is a commercial-grade mulching blade engineered to replace OEM 580244001, 580244002 and 587199603 for 22" cut Craftsman, Husqvarna, and Poulan mowers.

Designed and manufactured in the USA to meet or surpass OEM specifications, this 21-15/16" x 2-1/2" mulching blade features a 5-point star center hole and a centrifugal air-lift profile to shred grass evenly and improve decomposition. It arrives with a temporary safety coating that protects hands during handling and dissipates once the blade spins. Built for commercial use, the MaxPower 331749XB emphasizes larger cutting surface area and sharpened teeth for cleaner cuts and better mulching performance compared with standard replacement blades.

What mower models and OEM numbers does this blade replace?

This blade is sized and hole-patterned to fit many 22" cutting decks from Craftsman, Husqvarna and Poulan. It is specified as a direct replacement for OEM numbers 580244001, 580244002 and 587199603, so it matches the mounting and balance characteristics of the originals.

• Replaces OEM 580244001, 580244002, 587199603
• 5-point star center hole for correct fit and secure mounting

How does this blade improve mulching and lawn finish?

The commercial mulching shape increases cutting surface and uses sharpened cutting teeth to finely chop grass before it falls back to the lawn. Its centrifugal air-lift design creates circulating airflow under the deck that helps distribute clippings uniformly for faster decomposition and a neater appearance.

• Wider cutting edge increases mulching contact area
• Sharpened teeth provide cleaner, more consistent cuts
• Air-lift profile promotes circulation for even clipping distribution

What are the blade dimensions and handling features?

The MaxPower 331749XB measures 21-15/16" long and 2-1/2" wide, with a five-point star center hole matching many 22" mower spindle patterns. For safety in transit and installation, it carries an extra paint coating that temporarily dulls the edge for handling and removes after initial operation.

• Length: 21-15/16"; Width: 2-1/2"
• Center: 5-point star mounting hole for compatibility
• Temporary protective paint coating for safer handling
