Maxpower 3-Blade Replacement Set for 50-inch Mowers — USA Made OEM-Fit Powder-Coated Steel (17.9 in)

MaxPower 561545B is a three-blade replacement set made in the USA for many 50-inch MTD, Cub Cadet and Troy-Bilt lawn mower decks.

If your mower uses the OEM blade numbers listed for MTD, Cub Cadet, Troy-Bilt, Toro or Windsor, this three-pack provides factory-sharpened, powder-coated steel blades sized to the original specification. Each blade measures 17-29/32 inches long and 2-1/2 inches wide, with a six-point star center hole designed to match the specified mower spindles. These blades are finished with a protective powder coat that wears off during the first cut to reveal the precision-sharpened edge.

Which mower models and OEM numbers does this blade set replace?

The 561545B set is built to replace many OEM part numbers used across several brands—verify your owner’s manual to confirm compatibility before purchasing.

• Compatible OEM numbers include: 742-04053A/B/C, 742-04056/A/B/C, 942-04053A/B/C, 942-04056/A/C and similar 742/942 series.
• Also replaces Toro 112-0316 and Windsor 50-2138 where the mower uses the same dimensions and star hole.
• Intended for many 50-inch decks from MTD, Cub Cadet and Troy-Bilt that require a 17.9" blade length.

How do I confirm these blades will fit my mower?

Measure your current blade and check the OEM number stamped on it or consult your mower’s parts diagram. This ensures you match length, width and center hole pattern before ordering.

• Blade length: 17-29/32 inches (17.9 in).
• Blade width: 2-1/2 inches.
• Center mounting: 6-point star hole—match to your spindle bolt pattern.
• If your mower is a newer RZT (2015+), consider MaxPower 561558B for shorter blade options.

What are the construction and finish details of MaxPower blades?

MaxPower manufactures these blades in the USA to meet or exceed OEM tolerances. Each blade is sharpened during fabrication and then powder coated to protect the edge in transit and storage.

• Factory sharpened for consistent cutting geometry right out of the box.
• Powder coat protects finish; coating will rub off in the first few cuts.
• Heat-treated steel for strength and durability under normal lawn use.

How should I install and maintain these blades for best performance?

Install all three blades on the deck following your mower manufacturer’s torque and safety instructions. Keep blades balanced and routinely inspect for nicks or bends to maintain an even cut and avoid vibration.

• Always disconnect spark plug before servicing the mower deck.
• Torque mounting bolts to the mower manufacturer’s specification.
• Balance blades after installation and sharpen or replace when damaged.

Who is this for: The MaxPower 561545B three-blade set is aimed at homeowners and landscapers who own 50-inch MTD, Cub Cadet or Troy-Bilt decks that use the OEM numbers referenced above. Choose this set if you want American-made replacement blades that arrive factory-sharpened and ready to install, but be sure to confirm your blade length and center hole type before ordering to avoid fitment issues. If your mower is a newer RZT model requiring a shorter blade, look at MaxPower 561558B instead.
