MaxPower 561547B 2 Blade Set for 42 in. Cut MTD, Cub Cadet, Troy-Bilt Mowers Replaces OEM no. 759-3830, 742-3033 and 742-04101

What It Is

The MaxPower 561547B is a two-blade aftermarket set designed for 42-inch cutting decks on MTD, Cub Cadet, and Troy-Bilt lawn tractors. It replaces OEM numbers 759-3830, 742-3033, and 742-04101, intended for standard residential mowing on medium-sized lawns.

Fitment & Compatibility

Before buying, verify your deck size is exactly 42 inches (measure center-to-center of blade mounting holes). This set fits most MTD-built tractors from the 1990s onward, including Cub Cadet LT/LTX/GT series, Troy-Bilt Bronco/Pony, and Yard-Man models. Check your current blade’s part number against 759-3830, 742-3033, or 742-04101. Blades measure 20.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset. They do not fit zero-turn mowers or 46-inch+ decks. Confirm your spindle uses a single center bolt (not a three-bolt pattern).

Key Things to Know

• Quality: Heat-treated steel with a painted finish; holds an edge well for 1-2 seasons on typical lawns but dulls faster on sandy or rocky soil.
• Installation: Straightforward—remove the center bolt, swap blades, torque to 70-80 ft-lbs. Use a blade removal tool to prevent spinning; an impact wrench helps.
• Common gotcha: Blades ship with a protective coating—wipe it off before first use to avoid poor cutting performance. Also, check that both blades are identical; some OEM sets use a left/right orientation, but these are universal.
• Balance: Some users report minor imbalance out of the box; consider having them professionally balanced or use a blade balancer to prevent vibration.

Should You Buy It

Buy this set if you own a 42-inch MTD, Cub Cadet, or Troy-Bilt tractor and need a reliable, affordable replacement for OEM blades. It’s a solid value for light to moderate use, but if you mow heavy grass or rough terrain often, consider a thicker, premium-grade blade for longer life.
