Selecting replacement maxpower lawn mower blades requires balancing mower deck width, spindle mount geometry, and cutting performance. Homeowners maintaining residential turf often deal with ragged grass tips, torn blades, and clumping when an original blade loses its edge or suffers impact damage from surface debris. The choice comes down to matching the precise original equipment manufacturer (OEM) part number stamped on the existing blade and choosing between standard high-lift designs and specialized mulching profiles. Determining which maxpower blade to buy depends on whether your yard routine demands fine recycling of clippings directly into the soil or clean, high-velocity discharge across expansive acreage.

The MaxPower catalog organizes its replacement blades around specific mower deck footprints and drive patterns rather than one-size-fits-all hardware. The lineup divides into dedicated single-blade configurations for walk-behind mowers, multi-blade sets engineered for riding lawn tractors, and heavy-duty triple sets intended for commercial zero-turn decks. Each model is engineered around exact spindle interfaces, including MTD-style bow tie cutouts, standard five-point star tractor mounts, round commercial spindle bores, and universal multi-bushing adapters. Comparing maxpower usa made blades highlights how the manufacturer focuses on factory powder coating to protect cutting edges during transit, pre-sharpened profiles that shed paint on the initial cut, and application-specific steel dimensions to meet or exceed original deck specifications.

MaxPower Lawn Mower Blades Lineup at a Glance

The Models in Detail

01 Maxpower 331528B USA MADE 21″ Cut Includes 1 mulching blade for many 21 in

Check price on Amazon Our score: 8.0/10

Best for: Walk-behind MTD and Cub Cadet push mowers

Pros

• Direct bow tie OEM replacement
• Pre-sharpened factory edge
• Made in USA

Cons

• Not compatible with round spindle shafts

The Maxpower 331528B USA MADE 21″ Cut is a single mulching blade engineered specifically for 21-inch walk-behind mowers across MTD, Cub Cadet, Troy-Bilt, and Craftsman brand families. The listing confirms that this blade replaces OEM numbers 742-0741, 742-0741A, 742-04276, 742-04276S, 942-0641, 942-0741, 942-0741A, 942-04276, 942-04276S, and CC-742-0741, as well as Craftsman part number CMXGZAM100067. It features a bow tie center hole pattern where the outside holes measure 5/16 inch in diameter with a 2.5-inch center-to-center measurement. Homeowners servicing residential push mowers will find that this geometry locks directly onto proprietary MTD star-and-bowtie spindle shafts without play or vibration.

Measuring 21 inches in length and 2-1/4 inches in width with an item weight of 1.6 pounds, this blade operates within standard deck clearance tolerances for 21-inch walk-behind units. Like other maxpower usa made blades, it comes sharpened during manufacturing and is finished with an exterior powder coating for user protection. This coating comes off during the first cut to reveal the precision sharpened cutting edge beneath. For homeowners using walk-behind equipment on standard suburban plots, installing this maxpower mulching blade 21 inch configuration turns grass clippings into fine mulch that returns cleanly to the soil surface.

This model suits homeowners operating Cub Cadet CC or SC series mowers, or Troy-Bilt TB line machines like the TB 110, TB 130, or TB 230, who need a direct bolt-on OEM replacement. If your push mower lacks the proprietary bow tie spindle pattern and relies instead on a standard round center hole, this model gives way to the universal configuration offered by the MaxPower gold mulching blade.

02 MaxPower 561739B USA MADE 2 Blade Includes 2 blades that fit many 46 in

Check price on Amazon Our score: 8.6/10

Best for: Craftsman and Husqvarna 46-inch riding tractors

Pros

• Matched two-blade deck balance
• Secure 5-point star center
• Heavy-duty 4.8-pound construction

Cons

• Excludes replacement spindle mounting bolts

The MaxPower 561739B USA MADE 2 Blade set provides two matching replacement blades designed for 46-inch riding lawn tractors manufactured by Craftsman, Husqvarna, and Poulan. The product listing states that this set directly replaces OEM part numbers 405380, 594892801, 532405380, and PP21011, while also fitting Craftsman numbers CMXGZAM110146 and CMXGZAM110147. Each blade in the pair measures 23 inches in length and 2-3/4 inches in width, creating a continuous 46-inch cutting path inside a dual-spindle deck. While smaller boutique yards might be maintained with compact manual gear like a scotts reel mower, larger lawns require the balanced cutting power provided by matched tractor blades.

Both blades feature a 5-point star center hole pattern engineered to seat over tractor mandrel shafts, preventing slippage under heavy cutting resistance. Weighing a combined 4.8 pounds, these blades carry the mass needed to maintain momentum when cutting thick turf. MaxPower manufactures these blades in the USA to meet or exceed OEM specifications, sharpening the steel during production and sealing the metal with a protective powder coating. Incorporating this two-blade set into seasonal tractor maintenance restores crisp discharge velocity, reducing deck clogging when working through regular weekly mowing routines.

This package suits owners of mid-sized residential lawn tractors with 46-inch decks who need to replace both cutting edges simultaneously to preserve deck balance. However, if your riding tractor uses a smaller twin-blade deck footprint, you will need to step down to the 42-inch dual set, or step up to a triple-blade arrangement if operating a wider 54-inch mower.

03 MaxPower 561738XB USA MADE 3 Blade Includes 3 commercial mulching blades for 54 in

Check price on Amazon Our score: 8.2/10

Best for: Wide 54-inch tractor lawn mulching setups

Pros

• Sharpened mulching teeth design
• Centrifugal air lift profile
• Commercial-grade steel construction

Cons

• Fits only 5-point star spindles

The MaxPower 561738XB USA MADE 3 Blade commercial mulching set is engineered specifically for wide 54-inch decks found on large Craftsman, Husqvarna, and Poulan garden tractors. According to the listing, these three commercial mulching blades replace OEM numbers 187254, 187255, 187256, 594892901, 532187255, and 532187256. Each individual blade measures 18-1/2 inches in length and 3 inches in width, built with an integrated 5-point star center hole that aligns with three-spindle residential tractor decks.

Unlike standard high-lift factory blades, this maxpower 3 blade commercial mulching set features expanded cutting surfaces with sharpened cutting teeth along the rear sails. The listing highlights a specialized centrifugal air lift design that keeps clippings suspended under the deck for uniform chopping distribution. When sourcing replacement components like craftsman lawn tractor parts, choosing dedicated mulching profiles reduces the need to rake or empty collection hoppers across large open lawns. The total shipping weight is 3.95 pounds, and all three blades come pre-sharpened beneath their protective powder finish.

Property owners managing multi-acre lawns with 54-inch tractors who want clean, bag-free mulching will appreciate the aggressive serrated teeth on this triple set. If your tractor deck is narrower, such as a standard 42-inch or 46-inch setup, or if you operate a commercial 60-inch zero-turn rig with circular spindles, this 54-inch star-mount package will not mount to your deck spindles.

04 MaxPower 561713B 2-Blade Set for 42″ Replaces OEM numbers 127843, 138498, 138971, 138971X431, 532138971

Check price on Amazon Our score: 9.8/10

Best for: Standard 42-inch twin-spindle residential tractors

Pros

• Direct OEM replacement geometry
• Even side-discharge grass flow
• Durable powder-coated finish

Cons

• Limited to 42-inch deck widths

The MaxPower 561713B 2-Blade Set for 42″ is tailored for the most common residential lawn tractor size, fitting 42-inch cut decks on Poulan, Husqvarna, and Craftsman mowers. The listing verifies that this dual-blade package replaces factory OEM numbers 127843, 138498, 138971, 138971X431, 532138971, 532127843, 532138498, and Craftsman CMXGZAM110136 (also listed as 53-21278-43 and 53-21384-98). Each blade in this set measures 21 inches in length and 2-1/4 inches in width, delivering exact OEM geometry for balanced two-spindle rotation.

Designed with a standard 5-point star center hole, these blades mount straight to the star-shaped spindles on popular entry-level riding tractors. Total item weight for the pair is 3.9 pounds, giving the blades sufficient mass to resist deflection when trimming dense spring turf. In an objective maxpower blade comparison, this maxpower 561713B 42 inch blade set mirrors the factory lift profile, throwing clippings evenly out the side discharge chute or into an attached collection hopper. They are manufactured in the USA, sharpened at the plant, and coated with powder paint to protect the metal until put to work.

This set is the exact replacement solution for standard 42-inch twin-spindle residential tractor owners who need dependable factory replacement geometry. If your cutting chores have expanded and you operate a wider 46-inch mower, you will need to select the 561739B pair instead, as the 21-inch length of these blades leaves an uncut center strip in larger decks.

05 MaxPower 561139B USA MADE Heavy Duty Includes 3 blades for many 60 in

Check price on Amazon Our score: 8.8/10

Best for: Commercial Exmark 60-inch zero-turn operators

Pros

• Heavy-duty commercial build
• Large 15/16-inch center bore
• Three-blade full deck coverage

Cons

• Unsuitable for residential star-mount tractors

The MaxPower 561139B USA MADE Heavy Duty set includes three commercial-grade blades built specifically for 60-inch cut Exmark commercial mowers. As specified in the listing data, these blades replace Exmark OEM numbers 103-6403, 103-6403-S, and 140-1240. The set fits an extensive range of Exmark commercial units, including the CT, Front Runner, Laser HP, Laser Z, Laser Z E, Laser Z S, Laser Z X, Laser Z XP, Laser Z XS, Phaser, Pioneer, Quest, SP, Turf Ranger, Ultra Cut, and Vantage models.

Each blade in this maxpower 561139B exmark 60 inch triple set measures 20-1/2 inches in length and 2-1/2 inches in width. Unlike consumer tractor blades that rely on star-shaped centers, these commercial blades feature a round 15/16-inch center hole diameter engineered for heavy-duty commercial spindle bolts. Weighing 5 pounds across the set, these thick steel blades handle high blade tip speeds and demanding daily mowing schedules across expansive commercial grounds. They ship factory sharpened under a durable powder coating that prevents rust in damp trailer storage.

Commercial landscape contractors and property owners running 60-inch Exmark zero-turn rigs will find this heavy-duty set matches their high-torque operational demands. If you manage your turf using smaller walk-behind battery or gas mowers, or even specialized alternative machinery such as a senix lawn mower blade setup, this heavy 60-inch commercial tractor package will not match your spindle mounts or deck clearances.

06 Maxpower 331981B 21-Inch Universal Gold Metal Includes 1 universal replacement for 21 in

Check price on Amazon Our score: 9.2/10

Best for: Non-standard 21-inch walk-behind push mowers

Pros

• Includes six reducing washer adapters
• Aggressive mulching teeth profile
• Universal round bore adaptability

Cons

• Will not fit star-pattern spindles

The Maxpower 331981B 21-Inch Universal Gold Metal mulching blade is an adaptable 21-inch replacement designed to service a broad variety of push and walk-behind mowers. This blade measures 21 inches in length and 2-1/2 inches in width, featuring a 1-inch center hole. What sets this universal model apart is its included hardware package: it comes complete with one cover washer and six individual reducing washers sized at 3/8 inch, 7/16 inch, 9/16 inch, 1/2 inch, 5/8 inch, and 13/16 inch to adapt the main bore to almost any round walk-behind engine shaft.

Identified in listing details under part numbers 331981B and 331981S, this commercial-grade mulching blade features an extended cutting surface, sharpened cutting teeth along the raised sails, and a centrifugal air lift design. These features create continuous vertical airflow under the mower deck to repeatedly chop grass blades into microscopic pieces. Weighing 2 pounds and manufactured in the USA, the maxpower 331981B gold mulching blade provides a heavy-duty alternative to factory stamped push-mower blades, significantly upgrading mulching efficiency during high-growth summer periods.

This universal gold blade is ideal for homeowners with 21-inch push mowers that utilize round center shafts where an exact OEM replacement blade is discontinued or hard to trace. However, if your 21-inch mower utilizes an MTD-style bow tie spindle pattern, you should pass on this universal round-hole configuration and select the dedicated maxpower 331528B instead. Similarly, if your property routine requires the wide twin-blade capacity of a platform like the toro 30 inch wide cut lawn mower, this single 21-inch blade cannot be substituted.

Matching a Model to Your Setup

• For homeowners pushing a 21-inch Cub Cadet, Troy-Bilt, or MTD walk-behind mower with a bow tie spindle mount, the Maxpower 331528B USA MADE 21″ Cut delivers a direct factory fit that matches original deck clearances.
• For suburban yards maintained with a popular 42-inch twin-blade Craftsman, Poulan, or Husqvarna lawn tractor, the MaxPower 561713B 2-Blade Set for 42″ restores proper grass lift and clean side discharge.
• For operators managing mid-sized properties with a 46-inch dual-spindle tractor requiring 5-point star alignment, the MaxPower 561739B USA MADE 2 Blade set provides matched rotational balance across the deck.
• For large acreage mowing with a 54-inch lawn tractor where bagging is impractical, the MaxPower 561738XB USA MADE 3 Blade mulching set uses centrifugal air lift teeth to pulverize clippings.
• For professional landscapers and zero-turn operators running 60-inch Exmark decks with 15/16-inch round spindles, the MaxPower 561139B USA MADE Heavy Duty three-blade set provides commercial-grade durability.
• For older or off-brand 21-inch walk-behind mowers with non-standard round shafts, the Maxpower 331981B 21-Inch Universal Gold Metal blade adapts securely using its included six reducing washers.

Before You Buy

The listing details for the dedicated MaxPower replacement sets (including the 331528B, 561739B, 561738XB, 561713B, and 561139B) do not include mounting bolts, spindle nuts, spindle lock washers, or deck assembly hardware. Unless you are purchasing the universal 331981B model—which specifically provides a cover washer and six reducing spacer washers—the listings do not specify replacement hardware, meaning you must inspect and reuse your existing factory tractor spindle bolts or source new OEM-grade fasteners separately.

Furthermore, mower model numbers alone do not guarantee deck compatibility, as manufacturers frequently change spindle mandrel designs between production years. The listings explicitly emphasize that buyers must cross-reference the physical OEM part number stamped on their current blade and verify the center hole design—such as a 5-point star, a bow tie pattern, or a 15/16-inch commercial round bore—before ordering. The listings do not specify blade balance weights after initial seasonal sharpening or torque values for deck bolt installation, which must be verified against your mower’s original factory operator manual.

FAQ

Why do MaxPower lawn mower blades come covered in black or gold powder coating?

All MaxPower blades are sharpened during manufacturing and then coated with a protective powder finish. The listing notes that this coating shields the cutting edge during shipping and handling, and it wears off naturally during the first mowing session to reveal the sharpened steel underneath.

Can I install a 5-point star blade on an MTD mower that uses a bow tie spindle?

No. Spindle patterns are not interchangeable. A 5-point star center hole, such as the one on the MaxPower 561713B or 561739B, will not seat properly on an MTD bow tie spindle shaft, which requires the specific bow tie pattern found on the MaxPower 331528B.

What makes a commercial mulching blade different from a standard replacement blade?

According to the product descriptions for the 561738XB and 331981B sets, commercial mulching blades feature an expanded cutting surface, sharpened cutting teeth along the rear sails, and a centrifugal air lift design that keeps clippings recirculating beneath the deck for fine chopping.

What mounting hardware comes with the MaxPower universal gold mulching blade?

The MaxPower 331981B package includes one cover washer and six reducing washers in sizes 3/8 inch, 7/16 inch, 9/16 inch, 1/2 inch, 5/8 inch, and 13/16 inch to adapt its 1-inch center hole to various mower shaft diameters.

How do I verify which MaxPower blade fits my riding mower deck?

You must inspect the underside of your deck or check your operator manual to find the exact OEM part number stamped on your existing blade. Confirm both the cutting deck width and the center hole shape before matching them to the MaxPower part numbers listed in the specifications.
