Maxpower 3-Blade Mulching Set for 46" Mower Decks — USA Made, 2 Long + 1 Short Blades, 6-Point Star Mount

Maxpower 561540B is a three-blade mulching replacement set made in the USA for many 46" Cub Cadet, MTD, Troy-Bilt and compatible mower decks.

This kit contains one shorter blade and two longer blades engineered to match common OEM length, width and mounting patterns so you can restore cutting performance and mulching capability without buying a whole deck or expensive OEM parts. Each blade uses a six-point star center hole and is manufactured to meet or exceed original equipment dimensions and fitment.

Which mower models and OEM part numbers does this set replace?

The 561540B set was designed to be a direct fit for numerous 46" cutting decks from Cub Cadet, MTD, Toro and Windsor, among others. It’s matched to the same mounting hole pattern and blade profiles used by those factory blades.

• Long blades replace OEM numbers such as Cub Cadet 742-04125, 942-04125; MTD 742-0611, 942-0611; Toro 112-0304; Windsor 50-3935.
• Short blade replaces OEM numbers such as Cub Cadet 742-04124, 942-04124; MTD 742-0612, 942-0612; Toro 112-0302; Windsor 50-3940.
• Works with many 46" cut MTD, Cub Cadet and Troy-Bilt mower decks that use a 6-point star center mounting.

What are the blade dimensions, mounting pattern, and material details?

The set includes two longer blades and one shorter blade, sized to align with OEM geometry and deliver reliable mulching action. All blades share the same center mounting to simplify replacement.

• One short blade: 14-13/16" long by 2-1/2" wide with a six-point star center hole.
• Two long blades: 16-1/4" long by 2-1/2" wide each, also with the six-point star center hole.
• Manufactured in the USA to meet or exceed OEM tolerances for fit and balance.

How will these blades affect cutting and mulching performance?

Replacing worn or damaged blades with correctly sized, well-balanced parts restores even cutting height and improves clippings shredding. Proper blades help mulch leaves and grass more finely, which can reduce bagging and leave a neater finish on the lawn.

• Matched lengths and widths keep blade tips at the designed radius for even discharge and mulching.
• Sharp, OEM-profile edges cut cleanly to minimize tearing and uneven strips in the turf.
• Balanced manufacturing reduces vibration and protects spindle bearings over time.

How easy is installation and what tools are needed?

Installation is straightforward if you have basic hand tools and follow safety steps. Because these blades use the same six-point star center hole pattern as many OEM blades, swapping them in typically requires only a wrench and a secure means to block blade rotation.

• Required: socket or wrench sized for your mower blade nut, a block of wood or blade-locking tool, and gloves.
• Estimated time: 15–30 minutes for one deck for someone familiar with blade replacement.
• Always disconnect the spark plug and secure the mower before working under the deck.

Who is this for: The Maxpower 561540B three-blade mulching set is intended for homeowners, landscapers and lawn-care professionals who own 46" cut mowers from Cub Cadet, MTD, Troy-Bilt or compatible brands and need reliable, USA-made replacement blades that match OEM sizes and mounting. Choose this set if you want precise fitment, balanced blades for reduced vibration, and parts built to OEM specifications without paying OEM sticker prices.
