MaxPower 561545XB 3-Blade Commercial Mulching Set for Many 50" Cut MTD, Cub Cadet, Replaces OEM no. 742-04053, 942-04053,Black

What It Is

The MaxPower 561545XB is a three-blade mulching set designed for commercial-grade mowing on 50-inch cutting decks, specifically for MTD and Cub Cadet zero-turn or lawn tractors. It replaces OEM part numbers 742-04053 and 942-04053, offering an aftermarket alternative for heavy mulching applications.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 50 inches from blade tip to blade tip. This set fits many Cub Cadet and MTD models with 50-inch fabricated or stamped decks, including select RZT, Z-Force, and LT series. Verify your OEM blade part number matches 742-04053 or 942-04053—if your current blades are different (e.g., 742-04054), this set won’t work. Each blade is 17.75 inches long with a 1-inch center hole and 5-point star drive, so measure your existing blade length and center hole shape. Check your deck’s spindle pattern: this set uses three blades with a staggered offset design, not a straight gator-style pattern.

Key Things to Buy

• Quality: MaxPower blades are heat-treated steel, but some users report thinner gauge than OEM Cub Cadet blades—expect slightly faster dulling under heavy use or debris.
• Installation: Use a torque wrench to tighten to 70-80 ft-lbs; star drive can strip if overtightened. Mark blade orientation before removal to avoid balance issues.
• Common Gotchas: Mulching blades have a higher lift than standard blades, which can reduce bagging performance and increase engine load on wet grass. Balance each blade before installing—use a simple balancer to avoid vibration.
• Noise: The mulching design creates more airflow, so expect louder operation than standard blades.

Should You Buy It

If you own a 50-inch Cub Cadet or MTD with the exact OEM blade numbers and primarily mulch dry grass, this set offers solid value at a lower price than OEM. But if your deck uses a different blade pattern or you need maximum durability for commercial daily use, stick with OEM or step up to a thicker aftermarket brand.
