Description
xMaxPower 561746B is a three-blade replacement set of 21-inch lawn mower blades made in the USA to match or exceed OEM fit and cutting performance.
These MaxPower mower blades are manufactured from American steel and finished to meet the specifications of common residential mowers. Designed as direct replacements for specific Craftsman, Husqvarna, and Poulan part numbers, the set includes three identical 21-inch blades with a five-point star center hole for secure mounting. They’re intended for homeowners and landscapers who need reliable, consistent cutting edges without modifying their mower deck.
Which mower models will these blades fit?
The MaxPower 561746B three-blade set replaces several OEM part numbers and fits many common 21-inch residential decks that use a five-point star center mounting. Always confirm blade length, center hole pattern, and bolt orientation before purchase to ensure proper fitment and safety.
- Replaces OEM numbers: Craftsman, Husqvarna, Poulan 539113312 and 510417901
- Blade length: 21 inches overall for most 21" decks
- Center hole: 5-point star pattern for compatible spindle assemblies

How do these blades affect cutting quality and lawn health?
Sharp, properly sized blades produce clean cuts that help turf recover faster and reduce ragged edges that invite disease. MaxPower blades are stamped and finished to give consistent edge geometry across the set, so each pass delivers uniform grass clipping size and distribution.
- Precision-stamped edge geometry for even cutting
- Consistent balance to minimize vibration and wear
- Three-blade set keeps multi-blade decks cutting uniformly
- Made from US steel with a finish to resist premature rusting
What should I check before installing these replacement blades?
Confirm blade length, center hole pattern, and rotation direction; mismatched blades can cause poor cutting, deck damage, or unsafe operation. Also inspect spindle bolts, washers, and deck clearance for nicks or warping, and follow manufacturer torque specs when installing.
- Measure from tip to tip to verify 21-inch fit
- Match the five-point star center to your mower spindle
- Check blade rotation orientation (lift/low-lift or mulching fitment) before mounting
- Torque mounting hardware to mower OEM recommendations
