Maxpower 561735XB USA MADE 3 Blade Commercial Mulching Set

The MaxPower 561735XB commercial mulching set provides three replacement blades designed specifically for 48-inch decks on Craftsman, Husqvarna, and Poulan mowers. It solves the problem of worn, dull cutting assemblies by offering a direct replacement pack made in the USA to meet or exceed OEM specifications.

Each blade in the set measures 16-5/8 inches long and 2-1/2 inches wide, featuring a 5-point star center mounting hole. The blades are sharpened during manufacturing and finished with a protective powder coating. This layer protects the cutting edge during handling and comes off naturally during your first cut to expose the sharpened edge underneath.

Because these are built around exact OEM numbers (173921 and 532173921), compatibility is strictly limited to matching 48-inch models with 5-point star spindles. Decks requiring a 6-point star, round center holes, or different cutting lengths will not work with this set, so confirming your mower deck size and spindle shape beforehand is essential.

Verdict: This three-blade set is a solid, direct replacement choice for owners of compatible 48-inch Craftsman, Husqvarna, or Poulan mowers looking to refresh their mulching setup with factory-sharpened parts.
