MaxPower 561816B 3-Blade Set for 54" Cut John Deere, Replaces OEM no. M143520, UC22010

What It Is

The MaxPower 561816B is a set of three replacement blades designed for 54-inch cut John Deere lawn tractors and zero-turn mowers. It’s a direct aftermarket alternative to OEM blades M143520 and UC22010, intended for standard residential or commercial mowing.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 54 inches (measured blade tip to blade tip). This set fits most John Deere models with a 54-inch stamped or fabricated deck, including X500, X700, Z500, and Z700 series. Double-check your OEM part number: it replaces M143520 (John Deere) and UC22010 (Stens/others). Measure your existing blade length, center hole diameter (typically 1 inch), and thickness (0.25 inch). The MaxPower blades are 18.5 inches long with a 1-inch center hole and 0.25-inch thickness. Avoid buying if your deck uses a different hole size or offset pattern.

Key Things to Buy

• Quality: Made from heat-treated steel with a hardened edge. Users report good durability for residential use, but may dull faster than OEM on heavy or rocky terrain.
• Installation: Direct bolt-on for most 54-inch John Deere decks. Use a torque wrench to tighten to 70-90 ft-lbs (check your deck manual). No adapters or modifications needed.
• Common Gotcha: The blades may be slightly lighter than OEM, which can affect balance at high RPMs. Always balance the set after installation using a balancer to avoid vibration.
• Price vs OEM: At ~$36, it’s roughly 40-60% cheaper than John Deere OEM blades. Good value if you mow regularly but don’t need professional-grade longevity.

Should You Buy It

If you own a 54-inch John Deere mower and want a reliable, budget-friendly replacement blade set for routine mowing, this is a solid pick. It’s not ideal for commercial mowing or extremely abrasive conditions (sandy soil, frequent mulching), where OEM or premium aftermarket blades may last longer. For most homeowners, the price-to-performance ratio is excellent.
