#1 · Best Overall

1. MaxPower 561713B

• Dimensions: 21 x 2.25 x 1.25 in
• Weight: 3.9 lb

Best for: 42-inch deck replacement set.

Why it ranks #1: Two blades fit many 42-inch Poulan, Husqvarna, and Craftsman mowers; each is 21 inches long with a 5-point star center hole.

The two-blade set pairs a 21-inch length with a five-point star center hole, giving owners of compatible 42-inch Poulan, Husqvarna, and Craftsman mowers a direct replacement option. Its listed OEM references make it easier to check the current blade before choosing a match.

Each blade measures 21 by 21⁄4 inches, and the five-point star hole helps identify the mounting pattern to compare with the mower’s existing blade. The listed replacement numbers cover several Poulan, Husqvarna, and Craftsman applications, so checking the current OEM number is the practical fit step. MaxPower says the blades are sharpened during manufacturing and powder coated; that arrives ready for blade replacement, with the coating providing a protective finish.

Skip it if you need a 46-inch deck blade; MaxPower 561739B is listed for many 46-inch Craftsman, Husqvarna, and Poulan mowers.

A practical choice for owners of compatible 42-inch Poulan, Husqvarna, or Craftsman decks who need a two-blade replacement set. Match the mower’s current OEM number and five-point star center hole before ordering.

#2 · Broad 42-Inch Fit

2. Oregon D-42-2G

• Dimensions: 21 x 2.5 x 1.5 in
• Weight: 5 lb

Best for: 42-inch Husqvarna fit check.

Why it ranks #2: This two-blade set is for 42-inch decks, measures 21 by 2.5 inches, and lists numerous Husqvarna and Craftsman replacement numbers.

A 21-inch blade length, 2.5-inch width, and five-point star center hole define this Oregon replacement for compatible 42-inch decks. Its broad list of Husqvarna and Craftsman replacement numbers gives owners several ways to compare the blade against their mower’s existing part.

Oregon lists numerous replacement references, including 532138498, 532138971, and 127843, for Husqvarna and Craftsman applications. That gives owners a useful starting point for checking the manual or removed blade before installation. The stated 21-inch length, 2.5-inch width, and five-point star hole provide additional physical fit checks. Oregon also reports research and development focused on cut quality, lower noise, and precision balance, relevant to buyers considering operating performance as well as compatibility.

Skip it if you need a 46-inch deck replacement; MaxPower 561739B is listed for many compatible 46-inch mowers.

This is a fit-check option for Husqvarna or Craftsman owners with a compatible 42-inch deck and matching replacement number. Verify the five-point star hole and dimensions against the existing blade before installation.

#3 · 42-Inch Mulching

3. Husqvarna 42-Inch Mulching Blades

• Dimensions: 22 x 2.2 x 1 in
• Weight: 3.49 lb

Best for: Husqvarna 42-inch mulching.

Why it ranks #3: The two hardened-steel blades are specified for Husqvarna riding mowers, use a star mount, and replace OEM number 594892701.

Forged hardened steel is the key feature of these two Husqvarna 42-inch mulching blades, which the listing says are intended to run smoother, stay sharper, and cut more quietly. The star mount and replacement number 594892701 give owners specific checks for a compatible riding mower.

The pair is identified for Husqvarna riding mowers, and the star mount gives a physical detail to compare with the installed blade before replacement. The stated 594892701 OEM reference further narrows compatibility, so buyers can check the mower documentation or current part number. Husqvarna says the hardened-steel blades are designed to stay sharper and deliver quieter cutting; those claims make the set relevant to owners prioritizing mulching and a smoother operating experience, rather than a universal 42-inch fit.

Skip it if you need a 46-inch high-lift replacement; Grasscool 405380 is listed for specified 46-inch decks.

A focused choice for Husqvarna riding-mower owners seeking a 42-inch mulching pair with hardened-steel construction. Check that the mower uses the listed OEM number and star mount; the listing does not establish fit for all 42-inch decks.

#4 · 42-Inch High Lift

4. Husqvarna 532138971

• Dimensions: 24 x 4 x 4 in
• Weight: 1 lb

Best for: 42-inch high-lift replacement.

Why it ranks #4: These two high-lift blades are listed as 42-inch replacements for Craftsman, Husqvarna, Poulan, and AYP mower applications.

The 42-inch high-lift specification makes this two-blade pack relevant to owners seeking that blade style for listed Craftsman, Husqvarna, Poulan, and AYP applications. Its 532138971 model reference, alongside 138971 and 134149, gives a concrete starting point for identifying a replacement.

The listing identifies these as 42-inch high-lift blades and names Craftsman, Husqvarna, Poulan, and AYP as the intended mower brands. Those details help narrow the search, while the model and replacement references offer a check against the mower’s existing part. Because the supplied information gives limited fit details beyond those references, owners should rely on the current blade number and mower documentation when selecting it. The pack contains two blades for a paired replacement.

Skip it if you need detailed 42-inch mulching specifications; Husqvarna 596772301 lists a star mount and OEM replacement number.

A candidate for owners of listed Craftsman, Husqvarna, Poulan, or AYP 42-inch mowers who need high-lift blades. Check the mower’s existing number carefully, since model-level compatibility details are limited.

#5 · 46-Inch Deck Set

5. MaxPower 561739B

• Dimensions: 0.25"D x 2.75"W x 23"H
• Weight: 4.8 lb

Best for: 46-inch tractor blade pair.

Why it ranks #5: The two 23-inch blades fit many 46-inch Craftsman, Husqvarna, and Poulan mowers and use a 5-point star center hole.

At 23 inches long and 23⁄4 inches wide, each blade in this two-piece set is specified for many 46-inch Craftsman, Husqvarna, and Poulan mowers. The five-point star center hole and listed OEM references give owners useful checks before replacing their existing blades.

The 23-inch length and five-point star mounting hole help buyers compare this set with the installed blade, while the listed 405380, 594892801, and 532405380 references support an OEM-number check. MaxPower names several 46-inch mower brands, but the fit is not universal across every deck of that width. Compare the owner’s manual or current blade number before installation; the supplied pair addresses a two-blade replacement rather than a single blade.

Skip it if you need a high-lift blade specifically; Grasscool 405380 is identified as a high-lift replacement for listed 46-inch decks.

A suitable candidate for owners of compatible 46-inch Craftsman, Husqvarna, or Poulan mowers replacing a pair. Check the existing OEM number and center-hole shape carefully, since deck width alone does not establish fit.

#6

6. Grasscool 46-Inch High Lift

• Dimensions: 0.15"D x 2.7"W x 22.8"H
• Weight: 3.2 oz

Best for: 46-inch high-lift deck match.

Why it ranks #6: This high-lift replacement is specified for several 46-inch Husqvarna decks and lists compatible Craftsman YT3000 46-inch decks.

High-lift configuration is the defining feature here: Grasscool lists these replacements for specified 46-inch Husqvarna decks and models, including YTH and RZ series. The five-star mounting hole and extensive replacement-number list help owners check whether the blade suits their tractor or zero-turn mower.

Grasscool identifies the blades as replacements for several 46-inch stamped-deck Husqvarna tractors and RZ zero-turns, as well as Craftsman YT3000 with a 46-inch deck. That model detail is more useful for fit checking than deck width alone. The five-star mounting hole offers another physical comparison against the current blade, and the listed numbers include 405380 and 532405380. Its high-lift designation makes it the option to consider when that blade style is required.

Skip it if you need a 42-inch mulching pair; Husqvarna 596772301 is listed for 42-inch riding mowers.

Choose this for a listed 46-inch Husqvarna tractor, RZ zero-turn, or Craftsman YT3000 when a high-lift replacement is the goal. Verify the model, deck, OEM reference, and five-star mounting pattern before fitting.

#7

7. BDELI 942-04308

• Dimensions: 22.05 x 2.76 x 1.57 in
• Weight: 4.29 lb

Best for: 42-inch mulching deck owners.

Why it ranks #7: The two mulching blades target compatible 42-inch Cub Cadet, Troy-Bilt, and Craftsman T110 mowers, but require a 6-point star spindle.

The 942-04308 replacement number anchors this two-blade mulching set for listed 42-inch Cub Cadet, Troy-Bilt, and Craftsman applications. Its six-point star fit requirement gives buyers a concrete compatibility check, while the specified S-shape exclusion helps prevent choosing it for an incompatible spindle.

BDELI lists Cub Cadet XT1 LT42, ZT1, and RZT42, along with Troy-Bilt Bronco and Pony 42-inch deck applications. That model coverage can narrow the search, but the six-point star spindle pattern still needs verification before installation. The listing explicitly excludes S-shape center models, including Cub Cadet XT1/LT42 models using 742-05177. Checking both the mower’s model and spindle shape is therefore central to avoiding a mismatched blade set.

Skip it if you have an S-shape spindle; Husqvarna 596772301 is listed as a star-mount 42-inch mulching replacement.

This set suits owners of listed 42-inch Cub Cadet, Troy-Bilt, or Craftsman mowers seeking mulching replacements. Confirm the spindle has the specified six-point star pattern; the S-shape models identified in the listing are excluded.

#8

8. Oregon Gator G5 598-629

• Dimensions: 21.19"L x 3"W
• Weight: 0.27 g

Best for: Six-point star mulching decks.

Why it ranks #8: The two 21-3/16-inch mulching blades replace listed Cub Cadet and MTD numbers for compatible 42-inch applications with a 6-point star mount.

Tungsten carbide fused to the cutting edge distinguishes Oregon’s Gator G5 mulching blades, listed for compatible MTD and Cub Cadet applications. The 21-3/16-inch length and six-point mounting-hole requirement give buyers concrete checks, while the fused edge is intended to support longer blade life.

The 3-inch width and .164-inch thickness help identify the blade alongside its 21-3/16-inch length, while the six-point star hole is essential for fit. Oregon lists replacement numbers including 942-0616 and 742-04126, giving owners a way to compare the current part. The tungsten-carbide-fused edge is specified as a durability feature. Package-count information conflicts: the title says two-pack, while the additional description says four, so verify the supplied quantity before planning a replacement.

Skip it if you need a clearly stated 42-inch Husqvarna replacement; Husqvarna 596772301 is listed as a two-blade 42-inch set.

This suits owners of compatible MTD or Cub Cadet equipment seeking Gator G5 mulching blades with a carbide-fused edge. Confirm the six-point hole and replacement number, and resolve the conflicting package count before planning installation.

#9

9. GICOOL 942-0610A

• Dimensions: 22.24 x 2.76 x 1.57 in
• Weight: 4.49 lb

Best for: 38-inch MTD deck owners.

Why it ranks #9: This two-blade mulching set is specified for 38-inch MTD-family decks, including listed Troy-Bilt, Murray, and Huskee mower models.

This two-blade mulching set targets 38-inch MTD-family decks, with listed applications spanning Huskee, Murray, Troy-Bilt, and White Outdoor models. Its 742-0610 and 942-0610A replacement references help identify the intended fit, while the six-point star center hole offers a spindle-pattern check.

GICOOL lists specific 38-inch mower families, including Huskee LT3800, several Murray M115/M125/M135 models, and Troy-Bilt Tuffy. Those model references make it easier to narrow compatibility than relying on deck size alone. The listing identifies a six-point star center hole, which owners can compare against the existing spindle pattern. Blade measurements in the supplied specifications are inconsistent, however, so use the model and OEM references as the primary checks rather than relying on a single stated length.

Skip it if you need a 42-inch Cub Cadet mulching set; BDELI 942-04308 is listed for compatible 42-inch models.

Consider this pair for owners of the listed 38-inch Huskee, Murray, Troy-Bilt, or White Outdoor applications. Confirm the OEM number and star pattern, and account for the conflicting length details when checking the current blade.

#10

10. MaxPower 331528B

• Dimensions: 23 x 4 x 2 in
• Weight: 1.6 lb

Best for: 21-inch mower mulching blade.

Why it ranks #10: This single 21-inch mulching blade is for many walk-behind mowers, not riding mower decks, so it does not match the search use case.

A single 21-inch mulching blade serves many listed MTD, Cub Cadet, Troy-Bilt, and Craftsman mower applications. Its bow-tie center hole and replacement-number list make this a distinct option for owners checking an existing 21-inch mower blade rather than shopping for a riding-deck pair.

MaxPower lists multiple replacement references, including 742-0741 and 942-0741, and specifies a bow-tie center hole. Comparing both details with the current blade or mower documentation is the practical way to assess fit across the named brands. The product includes one blade, so it is suited to a single-blade replacement workflow rather than replacing a two-blade riding deck as a set. Its mulching designation identifies the intended blade type for compatible 21-inch-cut mowers.

Skip it if you need a two-blade 42-inch riding set; MaxPower 561713B is listed for compatible 42-inch decks.

Choose this for a compatible 21-inch-cut MTD, Cub Cadet, Troy-Bilt, or Craftsman mower needing one mulching blade. Confirm the bow-tie hole and OEM reference; it is not a paired riding-deck blade set.
