Maxpower mower blade set 42" replacement — 21-3/16" USA-made 2-blade pack, 6-point star center

Maxpower 561556B is a pair of USA-made replacement mower blades engineered to fit many 42" cutting decks from MTD, Cub Cadet, Troy-Bilt and select Craftsman models.

If your lawn tractor needs a reliable blade swap, this two-blade set offers a direct-fit replacement for several common OEM part numbers. Each blade is manufactured in the United States to match or exceed original equipment specifications, with a 6-point star center hole and precise dimensions to restore cutting performance and deck balance.

Will these blades fit my mower model?

These blades are designed to fit many 42" decks used across MTD, Cub Cadet and Troy-Bilt machines and are also compatible with a listed Craftsman model. Confirm fit by checking the OEM part number on your existing blade or your owner’s manual; the Maxpower set replaces multiple OEM numbers for broader compatibility.

• Replaces OEM 942-04312, 942-04308, 742-04308, 742-04312, 119-8456
• Compatible with Craftsman CMXGZAM110108
• Check owner's manual or stamped OEM number before ordering

What are the exact dimensions and center hole type?

Each blade in the 561556B set measures 21-3/16 inches long and 2-1/4 inches wide, matching the footprint of many factory blades for 42" decks. The center hole uses a distinctive 6-point star pattern to align with spindle shafts that require this configuration.

• Length: 21-3/16" (overall cutting edge length)
• Width: 2-1/4" (across the blade) for proper deck clearance
• Center hole: 6-point star for secure spindle fit

How do these blades affect cutting performance and maintenance?

Replacing worn or damaged blades with the correct size restores clean, even cuts and reduces strain on the mower deck and engine. Because Maxpower manufactures to meet or exceed OEM tolerances, these blades help maintain balance and minimize vibration when installed correctly and regularly sharpened.

• Restores sharp cutting edges for even turf results
• Balanced manufacturing reduces vibration and wear on spindles
• Durable steel construction holds edge longer between sharpenings

How do I install and care for these replacement blades?

Install one blade at a time following your mower’s service instructions, torque the spindle bolt to the manufacturer specification, and confirm the cutting edges face the correct rotation direction. Periodically inspect blades for nicks, bends, and balance; remove or replace any blade that shows significant damage.

• Follow torque specs in owner’s manual for safe installation
• Use blade balancing tools to verify even rotation after install
• Sharpen or replace when cutting quality declines or damage appears

Who is this for: The Maxpower 561556B blade set is intended for homeowners, landscapers, and service technicians who own 42" deck lawn tractors from MTD, Cub Cadet, Troy-Bilt, or the specified Craftsman models and want a reliable, USA-made OEM-equivalent replacement. Choose this set when you need an exact-dimension blade with a 6-point star center hole and a manufacturer that follows OEM tolerances for consistent cutting performance.
