Maxpower 3-Blade Commercial Mulching Set for 48" Decks — USA Made, 16-5/8" x 2-1/2", Sharpened Teeth

Maxpower 561735XB is a three-blade commercial mulching replacement set engineered for 48" cutting decks on Craftsman, Husqvarna and Poulan mowers.

If your mower uses OEM numbers 173921, 532173921 or 5321739-21, this Maxpower kit provides three ready-to-install mulching blades sized 16-5/8" long by 2-1/2" wide with a five-point star center hole. Built in the USA to meet or exceed OEM specs, these blades combine expanded cutting surface, sharpened teeth and a centrifugal air-lift design to improve grass chopping and distribution across the deck. Each blade is precision sharpened in manufacturing and receives a protective powder coat that will wear away on the first cut to reveal the finished edge.

How do these blades improve mulching performance?

These blades are shaped and sharpened specifically to produce finer clippings and more consistent return of mulch to the turf. The wider cutting surface helps break clippings into smaller pieces while the centrifugal lift mixes air with cut material for even distribution.

• Commercial-style wider cutting area for enhanced mulching
• Sharpened cutting teeth for cleaner, more efficient cuts
• Centrifugal air-lift design promotes uniform chopping and dispersal
• Powder-coating protects blade until first use, then reveals a precision edge

Will these blades fit my mower model and deck size?

These blades are intended for 48" cutting decks and replace common OEM part numbers listed by several manufacturers. Verify the blade OEM number in your owner's manual or on the existing blade before purchasing to ensure compatibility.

• Designed for 48" cut Craftsman, Husqvarna and Poulan machines
• Replaces OEM numbers 173921, 532173921 and 5321739-21
• Each blade measures 16-5/8" long and 2-1/2" wide
• Five-point star center hole aligns with standard spindle mounts for these models

What materials and finish are used, and how are the blades prepared?

Maxpower manufactures these blades to match or exceed OEM specifications using durable steel and a two-step finishing process. After precision sharpening, the blades receive a powder-coat that prevents corrosion and nicks during shipping; this coating intentionally wears off during the first mowing to expose the sharpened cutting surface.

• Heavy-duty steel construction meeting OEM strength and durability expectations
• Precision sharpening at the factory for immediate cutting performance
• Powder-coat finish for shipment protection that clears with first use
• Proudly made in the USA to OEM-equivalent standards

How should I install and maintain these mulching blades?

Installation follows standard mower blade replacement steps: disconnect spark plug, remove the old blade, match orientation, and torque the new blade to the spindle spec in your manual. Regular inspection and occasional re-sharpening keep performance consistent; replace blades if bent, cracked or excessively worn.

• Always disconnect spark plug before servicing the deck
• Align five-point star center hole with spindle mounting pattern
• Follow mower manufacturer torque specs for secure installation
• Inspect for damage and sharpen or replace as needed for optimal mulching
