Best Mulching Blades For Leaves for Push and Riding Mowers

#1 · Best Overall

1. Oregon Gator Blades

• Dimensions: 22.8 x 5.9 x 2.7 in
• Weight: 0.01 oz

Best for: 54-inch deck Gator mulching.

Why it ranks #1: Three Gator mulcher blades feature a high-lift angle and list fit references for Ariens, Husqvarna, Craftsman, Dixon, Murray, and Poulan.

Oregon’s high-lift Gator mulcher feature is intended to support mulching, making this three-blade set a leaf-focused option for compatible mower owners. The blades measure 18-7/16 inches and the listing names numerous Ariens, AYP, Craftsman, and other applications, including residential and commercial mowers.

The three heavy-duty blades have an 18-7/16-inch length and a stated superior cutting edge for enhanced mulching, connecting their construction details to leaf-cutting use. Oregon describes a high-lift blade angle as part of the Gator mulcher feature, while the fit list covers numerous mower models and brands. That breadth can help owners identify an application, but the listing references individual models and replacement numbers, so buyers need to match their mower rather than rely on deck size alone.

Skip it if you need a listed 42-inch Husqvarna YTH18542 pair; Oregon 96-900 Gator G3 blades are specified for that mower.

Consider the Oregon set if your mower matches one of its listed applications and you want the stated high-lift Gator mulcher design. Its model list is broad, but exact mower and blade-reference matching remains important.

#2 · Best Toothed Set

2. MowerPartsGroup Reaper Blades

• Dimensions: 18"L x 2.5"W
• Weight: 9 lb

Best for: 50- and 52-inch deck leaf mulching.

Why it ranks #2: Three toothed mulching blades explicitly list grass, leaves, and twigs, with compatibility for 50- or 52-inch cut decks.

Toothed Reaper blades and compatibility with 50- or 52-inch cut decks distinguish this three-blade set for owners of listed riding mower brands. MowerPartsGroup specifies compatibility with grass, leaves, and twigs, giving buyers a stated range of material for its mulching application.

The set contains three 18-inch blades, each specified at 21⁄2 inches wide and .250 inch thick, with a 5/8-inch center hole. Those dimensions and the listed compatible mower brands help identify the intended replacement application across 50- and 52-inch cut decks. The toothed mulching style is presented for grass, leaves, and twigs, while the powder-coated, made-in-USA description adds product details without changing the need to match the mower and mounting dimensions.

Skip it if you have a 54-inch Craftsman, Husqvarna, or Poulan mower; MaxPower 561738XB is specified for those 54-inch decks.

This set suits owners of compatible 50- or 52-inch deck mowers who want toothed blades listed for leaves and other yard material. Confirm the mower application and 5/8-inch center-hole requirement before choosing it.

#3 · Best Leaf-Specific Design

3. Mowrator S1 Blades

• Dimensions: 21.85"D x 2.13"W x 3.35"H
• Weight: 1.88 kg

Best for: Mowrator S1 leaf shredding.

Why it ranks #3: The S1-compatible three-pack uses a dual-stage, high-low design described for finer leaf cuts and stronger suction.

A high-low blade arrangement provides the defining feature of Mowrator’s three-pack: its stated dual-stage shredding is intended to make finer cuts and increase leaf suction. The blades are specified for Mowrator S1 models, focusing this option on owners of that mower rather than users seeking a general-purpose replacement.

Mowrator describes the high-low blade design as a dual-stage system for finer shredding and stronger leaf suction, directly addressing leaf processing. The blades are made from corrosion-resistant 40MnB steel, which the listing associates with strength and extended blade life. It also claims low power consumption to maximize suction while supporting longer battery life, and says installation is compatible with S1 models. That combination makes the set specifically relevant to S1 owners, not other mower platforms.

Skip it if you own a 54-inch Craftsman, Husqvarna, or Poulan mower; MaxPower 561738XB is listed for those 54-inch applications.

Choose this pack if you operate a Mowrator S1 and want its stated high-low shredding approach for leaves. Its compatibility is tied to S1 models, so it is not a general replacement choice for other mower brands.

#4 · Best 54-Inch Set

4. MaxPower 561738XB

• Dimensions: 19.75 x 3 x 0.63 in
• Weight: 3.95 lb

Best for: 54-inch riding mower leaf mulching.

Why it ranks #4: This three-blade commercial set is specified for 54-inch Craftsman, Husqvarna, and Poulan mowers and has five-point star center holes.

The three-blade set is specified for 54-inch Craftsman, Husqvarna, and Poulan mowers, giving owners of those decks a matched replacement set for mulching leaves. Its 181⁄2-inch blades have five-point star center holes, while the stated OEM references help identify the intended mower applications.

Each blade measures 181⁄2 inches long and 3 inches wide, and the set includes all three blades for the listed 54-inch applications. MaxPower says the blades are sharpened during manufacture, so the cutting edges are ready after installation; the powder coating comes off during the first cut. The five-point star center hole and listed replacement numbers provide concrete fit details, but the set is limited to the named mower families and matching configurations.

Skip it if you need a single 21-inch walk-behind blade; MaxPower 331528B is specified for many 21-inch MTD, Cub Cadet, Troy-Bilt, and Craftsman mowers.

Choose this set if your 54-inch Craftsman, Husqvarna, or Poulan mower matches the listed blade references and uses the five-point star center hole. Its three-blade quantity suits that specified deck application, not a 21-inch walk-behind.

#5 · Best 42-Inch Set

5. MaxPower 561713XB

• Dimensions: 21 x 2.5 x 0.75 in
• Weight: 5.2 lb

Best for: 42-inch Craftsman rider mulching.

Why it ranks #5: The two 21-inch blades are specified for 42-inch Craftsman, Husqvarna, and Poulan riders, with a five-point star mounting hole.

Two 21-inch commercial mulching blades make this MaxPower set a targeted replacement for listed 42-inch cut Craftsman, Husqvarna, and Poulan riders. The five-point star center hole and multiple OEM references help identify the intended fit, while the listing explicitly excludes Craftsman models manufactured by MTD.

Each blade measures 21 inches long by 21⁄2 inches wide, and the two-piece set is specified for a 42-inch cut. MaxPower lists numerous OEM replacement numbers and says it fits Craftsman models manufactured by Husqvarna, helping owners distinguish the intended application. The five-point star center hole is another mounting detail to match. MaxPower states that blades are sharpened during manufacture and powder coated, with the coating coming off during the first cut.

Skip it if you own a 54-inch Craftsman, Husqvarna, or Poulan mower; MaxPower 561738XB is listed for compatible 54-inch decks.

Choose this set for a compatible 42-inch rider, especially a listed Husqvarna-manufactured Craftsman, Husqvarna, or Poulan model. The MTD-manufactured Craftsman exclusion is decisive, so verify that distinction alongside the OEM reference.

#6

6. Rotary 12920 Copperhead

• Dimensions: 24 x 5 x 4 in
• Weight: 5.09 lb

Best for: Three-blade Copperhead replacement.

Why it ranks #6: This three-blade toothed Copperhead set supplies 17-inch cutting lengths and a 0.678-inch center hole; verify all mounting details.

Rotary supplies three toothed Copperhead mulching blades, a clear match for buyers seeking a set rather than a single replacement blade. The listed 17-inch cutting length and 0.678-inch center hole are useful identification details, alongside specified width, thickness, and outer-hole dimensions.

The pack includes three blades with a 17-inch cutting length, 21⁄2-inch width, and .160-inch thickness, giving buyers several dimensions to compare with their existing equipment. Rotary also specifies a .678-inch center hole and .411-inch outer holes, which are relevant mounting details when identifying a replacement. The listing advises checking the owner’s or parts manual for fitment, so the product’s stated dimensions should be matched to the mower rather than treated as universal compatibility.

Skip it if you want a blade set with named 50- or 52-inch deck applications; MowerPartsGroup Reaper R15006-3 lists those deck sizes and compatible brands.

Choose this three-blade set if its 17-inch length and hole dimensions match your mower’s manual and you want toothed Copperhead blades. The listing does not name mower models, so application matching is essential.

#7

7. Rotary 13367 Copperhead

• Weight: 6.84 lb

Best for: 36-inch Husqvarna deck owners.

Why it ranks #7: The three-blade set is listed for a 36-inch cut Husqvarna mower, with 173⁄4-inch blades and a five-point star center.

This three-pack is listed for a 36-inch cut and Husqvarna replacement number 574870801, giving owners of that specified deck application a concrete starting point. Its 173⁄4-inch blade length, five-point star center hole, and 21⁄2-inch width provide additional details for matching a replacement.

Rotary’s listing identifies the blade as a mulcher for a 36-inch cut and gives Husqvarna 574870801 as the replacement reference. The 173⁄4-inch length, 21⁄2-inch width, .204-inch thickness, and five-point star center hole help buyers compare the blade to their current equipment before installation. Three blades are indicated by the PK3 title, making this a set rather than a single-blade purchase. The stated application is specific, so other deck configurations are not established by the supplied details.

Skip it if you have a 42-inch Husqvarna YTH18542; Oregon 96-900 Gator G3 is specifically identified for that mower.

This pack suits owners whose 36-inch mower application matches Husqvarna reference 574870801 and the listed blade dimensions. Its stated fit is specific, so choose another application-specific set if your deck differs.

#8

8. Oregon 96-900 Gator G3

• Dimensions: 1 x 1 x 1 in
• Weight: 6.84 lb

Best for: 42-inch Husqvarna YTH18542 owners.

Why it ranks #8: The two blades are specified as 21 inches long with a five-point star center, but the listing targets a 42-inch Husqvarna YTH18542.

This two-pack is identified as Oregon 96-900 Gator G3 blades for the 42-inch Husqvarna YTH18542, giving owners of that named mower a specific replacement option. Each blade is listed at 21 inches long, with a five-point star center hole and 3⁄4-inch air lift.

The two-blade pack is identified for the 42-inch Husqvarna YTH18542, making its stated application more specific than a broad mower-family listing. Its 21-inch length, 2.50-inch width, and .187-inch thickness provide dimensions for checking the replacement blade, while the five-point star center hole and 3⁄4-inch air lift add mounting and blade-profile details. These specifications can guide selection, but the supplied information does not establish additional mower compatibility beyond the named application.

Skip it if you need a three-blade set for a 54-inch deck; MaxPower 561738XB lists three blades for compatible Craftsman, Husqvarna, and Poulan mowers.

This pack fits the stated use case for owners of a 42-inch Husqvarna YTH18542 seeking two Gator G3 blades. The listing’s specific mower identification makes it a focused choice, so other applications need separate confirmation.

#9

9. MaxPower 331528B

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

Best for: 21-inch walk-behind mower owners.

Why it ranks #9: This single 21-inch replacement serves many MTD, Cub Cadet, Troy-Bilt, and Craftsman mowers, but its listing does not identify leaf-specific features.

A single 21-inch mulching blade makes this MaxPower option relevant to owners replacing one blade on many MTD, Cub Cadet, Troy-Bilt, and Craftsman mowers. Its bow-tie center hole and extensive OEM reference list help narrow compatibility, with the supplied guidance stressing a match to the current blade number.

The blade measures 21 inches long and 21⁄4 inches wide, and its bow-tie center hole gives buyers a useful mounting detail to compare with their existing blade. MaxPower lists numerous replacement numbers and mower families, which can help identify a matching application before installation. The package includes one blade, so it suits a single-blade replacement rather than supplying a complete multi-blade deck set; the manufacturer specifically advises matching the current OEM number.

Skip it if you need three blades for a 54-inch rider; MaxPower 561738XB supplies a three-blade set for listed Craftsman, Husqvarna, and Poulan mowers.

This is a practical candidate for owners of compatible 21-inch walk-behind mowers replacing one mulching blade. Check the current blade’s OEM number and bow-tie mounting pattern; the listing does not make it a universal 21-inch fit.

#10

10. Grasscool 21-Inch Blade

• Dimensions: 0.9 x 2.3 x 20.8 in
• Weight: 3.2 oz

Best for: 21-inch mower replacement shoppers.

Why it ranks #10: The replacement fits many 21-inch walk-behind mowers, but the supplied details do not establish a leaf-focused mulching design.

Broadly listed compatibility across walk-behind, push, and self-propelled 21-inch mowers is the key draw of this Grasscool replacement blade. Its references include Troy-Bilt, Cub Cadet, MTD, Craftsman, and other named brands, making the long replacement-number list useful when identifying a candidate for leaf mulching.

Grasscool lists a 21-inch cutting deck and multiple blade replacement numbers, linking the product to specified walk-behind, push, and self-propelled mower applications. The long brand list includes Troy-Bilt, Cub Cadet, MTD, Craftsman, and others, which helps owners compare their mower family and existing blade references. The listing also emphasizes deck size, mounting pattern, lift, and cutting style as selection details, so buyers should treat compatibility as application-specific rather than assuming every 21-inch mower fits.

Skip it if you need a three-blade set for a 54-inch deck; MaxPower 561738XB lists three blades for compatible Craftsman, Husqvarna, and Poulan mowers.

Consider this blade if your 21-inch walk-behind mower matches the listed replacement references and mounting details. The wide brand coverage does not eliminate the need to match the deck and blade application.
