942-04290-X Mulching Blade Set for 46" Cut MTD, Cub Cadet, Troy-Bilt, 561544XB, 742-04290-X, 942-04361, 742P04290AX

What It Is

The 942-04290-X is a three-blade mulching blade set designed for 46-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt lawn tractors. It replaces OEM part numbers 561544XB, 742-04290-X, 942-04361, and 742P04290AX, and is intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 46 inches from spindle to spindle. This set fits MTD, Cub Cadet, and Troy-Bilt tractors with a 46-inch deck and a 3-blade spindle pattern. Check your current blade part number against the listed OEM numbers (561544XB, 742-04290-X, etc.). Measure blade length (typically 16.5 inches for this set), center hole diameter (usually 1 inch), and center-to-center distance for the mounting holes. Not compatible with 42-inch or 54-inch decks. Verify your spindle bolt pattern matches a standard 5-point star or similar—some older models may vary.

Key Things to Know

• Mulching vs. standard blades: These have a curved, high-lift design to recirculate clippings. They won’t bag or discharge as effectively as standard blades.
• Installation difficulty: Moderate—requires a socket wrench and possibly a blade removal tool. Torque bolts to 40-50 ft-lbs per manufacturer spec.
• Common gotcha: The “X” suffix indicates a mulching variant; ensure your deck is set up for mulching (plug installed, discharge chute blocked).
• Quality: Aftermarket at $25.88—priced below OEM but with solid 4.7-star rating from only 4 reviews, so verify fitment carefully.

Should You Buy It

This is a solid, budget-friendly option if you own a 46-inch MTD/Cub Cadet/Troy-Bilt tractor and want to improve mulching performance without paying OEM prices. It’s best for homeowners who mow regularly and prefer leaving clippings on the lawn. Skip it if you need bagging or side-discharge blades, or if your deck is a different size.
