MaxPower 561548B 2-Blade Set for many 42" Cut MTD, Cub Cadet, Troy-Bilt Mowers Replaces OEM #s 742-04308, 942-04308, 742-0656, 942-0656

What It Is

The MaxPower 561548B is a set of two replacement blades designed for 42-inch cutting decks on popular MTD-built lawn tractors, including Cub Cadet, Troy-Bilt, and other brands. These blades are intended for standard grass cutting, not mulching or bagging, and serve as a direct aftermarket alternative to OEM blades.

Fitment & Compatibility

Before buying, measure your existing blade length—these are 20.5 inches long with a 1-inch diameter center hole and a 0.375-inch offset. They fit 42-inch decks on models from Cub Cadet (e.g., LT1042, GT1554), Troy-Bilt (e.g., Pony, TB42), and MTD (e.g., Yard Machines, Yard-Man). Confirm your OEM part number matches one of these: 742-04308, 942-04308, 742-0656, or 942-0656. Also verify your spindle pattern—these use a 5-point star center hole, not a round or oval hole. Check your deck’s blade orientation (some require a specific “L” or “R” side) and ensure the blade’s air lift matches your deck design.

Key Things to Buy

• Quality: These are heat-treated, hardened steel blades with a painted finish. They’re durable for regular use but may not be as thick as premium OEM blades—expect a slightly shorter lifespan if you hit rocks or roots.
• Installation: Easy DIY job with basic tools (socket wrench and torque wrench). Use a blade removal tool or block the blade to prevent spinning. Torque to 40-50 ft-lbs. Always lift the deck or remove the battery for safety.
• Common Gotcha: The 5-point star hole can be tight on some spindles—use a file to deburr if needed. Don’t confuse these with 3-in-1 mulching blades; they’re strictly for side-discharge or bagging.
• Pairing: Always replace blades in sets (both sides) to maintain balance and cutting performance.

Should You Buy It

If you own a 42-inch MTD, Cub Cadet, or Troy-Bilt tractor and need affordable, reliable replacement blades for routine mowing, this set is a solid choice. It’s not for heavy-duty commercial use or specialized cutting (e.g., mulching), but for most homeowners, the price and ratings make it a worthwhile buy over pricier OEM options.
