Maxpower 561532XB 2 Blade Commercial Mulching Set for 42" Cut MTD, Cub Cadet, Troy-Bilt Mowers, Replaces OEM no. 942-0616, 742-0616, 942-04126

What It Is

The Maxpower 561532XB is a two-blade commercial mulching set designed for 42-inch cutting decks on MTD, Cub Cadet, and Troy-Bilt lawn tractors. It replaces OEM part numbers 942-0616, 742-0616, and 942-04126, intended for heavy-duty mulching applications where fine grass clipping is desired.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck (measure deck width from blade tip to blade tip). This set fits most MTD, Cub Cadet, and Troy-Bilt models using a 2-blade spindle configuration—common on LT, GT, and RZT series. Check your owner’s manual for OEM part numbers 942-0616, 742-0616, or 942-04126 to ensure direct replacement. Measure your existing blade’s length (should be ~20.5 inches), center hole diameter (typically 1-inch), and spindle pattern (usually oval or keyed). Verify deck clearance: these blades have a slight lift, so ensure no obstructions under the deck.

Key Things to Know

• Quality: These are heat-treated, tempered steel blades with a powder-coat finish. They’re heavier than standard blades, adding durability but also requiring a balanced installation.
• Installation: Moderate difficulty—needs a socket wrench and blade removal tool. Always use a torque wrench to tighten to 70–90 ft-lbs. Re-balance blades after sharpening if you notice vibration.
• Common Gotchas: The mulching design may not bag well; they’re best for side-discharge or mulching only. Check your deck’s baffle kit—some older decks need a mulching plug or baffle upgrade to work efficiently.
• Wear: Expect 25–50 hours of use before dulling, depending on grass conditions. Sharpen with a file or grinder, but avoid overheating the edge.

Should You Buy It

Buy this set if you own a 42-inch MTD, Cub Cadet, or Troy-Bilt with a 2-blade deck and want fine mulching without bagging. It’s a solid, affordable upgrade over OEM blades for heavy-duty mulching, but skip it if you primarily bag or need a standard lift blade.
