Maxpower 561546B 3 Heavy-Duty Blades for Many 50 in. Cut MTD, Cub Cadet, Troy-Bilt Mowers Replaces OEM #'s 742-04068, 759-04047, 759-4047, 942-04068 Black

What It Is

This is a set of three heavy-duty replacement blades designed for 50-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt lawn tractors. They are built for standard residential mowing on medium-to-large lawns and are a direct aftermarket alternative to OEM blade numbers 742-04068, 759-04047, 759-4047, and 942-04068.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 50 inches from blade tip to blade tip. This set fits many MTD, Cub Cadet, and Troy-Bilt models with that deck size, but not all—check your model number against the Maxpower fitment list or your OEM part number. The blades have a 1-inch center hole and a 5-point star drive pattern. Measure your old blade’s length (should be roughly 20.5 inches) and verify the center hole and drive pattern match. If your mower uses a different hole or pattern (e.g., oval or 7-point star), these won’t work.

Key Things to Know

• Quality: Made from heat-treated, tempered steel for durability. They’re thicker than some OEM blades, which can reduce bending but may slightly increase engine load.
• Installation: Straightforward if you have a socket set and a torque wrench. Torque the center bolt to 70-90 ft-lbs. Always sharpen new blades before first use—they come sharp but can benefit from a quick touch-up.
• Common Gotcha: These are universal-fit for the listed models, but some Cub Cadet or Troy-Bilt decks use a different blade offset or lift angle. If your old blades have a pronounced air-lift wing, measure the vertical clearance under the deck before installing to avoid scalping.
• Balance: Each blade is laser-cut and balanced, but it’s wise to check balance on a blade balancer after sharpening to prevent vibration.

Should You Buy It

If you own a 50-inch MTD, Cub Cadet, or Troy-Bilt tractor and want a durable, cost-effective replacement for OEM blades, this set is a solid choice. It’s best for homeowners who mow regularly and prefer a heavy-duty blade that resists wear over thinner OEM options. Avoid if your deck uses a non-standard blade pattern or if you need a mulching or high-lift blade for specialized cutting.
