Maxpower 561540B 3 Blade Mulching Set for Many 46 in. Cut MTD, Cub Cadet, Troy-Bilt Mowers Replaces OEM #'s 753-0847, 942-04125, 942-04124, 942-0611, 942-0612

What It Is

This is a set of three mulching blades designed for 46-inch cutting decks on select MTD, Cub Cadet, and Troy-Bilt lawn tractors. The blades are shaped to chop grass clippings into fine pieces and recirculate them into the turf, eliminating the need for bagging—ideal for regular mowing during active growth.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 46 inches from blade tip to blade tip. These blades replace OEM numbers 753-0847, 942-04125, 942-04124, 942-0611, and 942-0612. They fit many MTD-built models including Cub Cadet LTX1046, RZT50, and Troy-Bilt Super Bronco 46. Measure your existing blade length, center hole diameter (typically 1 inch), and thickness (usually 0.25 inch). The Maxpower set matches these dimensions, but verify your spindle pattern—these are for a three-blade deck, not two-blade. Check your mower’s model number against Maxpower’s online compatibility chart to avoid returning.

Key Things to Know

• Quality: Blades are made of hardened steel with a painted finish. They hold an edge reasonably well but may dull faster than OEM equivalents if you hit debris or thick weeds regularly.
• Installation: Easy if you have a socket wrench and a torque wrench. Lift the deck, block it securely, and replace one blade at a time. Torque center bolt to 50–60 ft-lbs—overtightening can strip the spindle.
• Gotchas: These are mulching blades only—they won’t bag or side-discharge well. If you switch between mulching and bagging, you’ll need a separate set. Also, the blade holes are slightly tight on some spindles; a light file touch can fix that.
• Balance: Each blade is balanced from the factory, but check with a blade balancer before installing—an unbalanced blade vibrates and wears spindle bearings.

Should You Buy It

Buy this set if you own a 46-inch MTD, Cub Cadet, or Troy-Bilt with a three-blade deck and want an affordable, drop-in mulching upgrade that keeps your lawn clean without bagging. Avoid if you need a universal fit or plan to bag or discharge—these are purpose-built for mulching only.
