#1 · Best Overall

1. yewposy Hinged Mulch Plug

• Weight: 7.8 oz
• Dimensions: 8.5 x 6.5 x 0.5 in

Best for: Troy-Bilt 21-inch walk-behind.

Why it ranks #1: Its 987-02516A plug is listed for 21-inch walk-behind mowers, with specific MTD and Troy-Bilt models and several replacement part numbers.

A detailed compatibility list for 21-inch push mowers, including named Troy-Bilt TB110 and TB130 examples, makes this hinged plug easy to assess against specific walk-behind models. The 987-02516A number and several alternate references further support a part-number-based fit check.

This plug lists 987-02516A, 987-02516, 687-02516, 687-02516A, 68702516 and 98702516, giving owners several identifiers to compare with their existing part. The compatibility examples include MTD model codes and dated Troy-Bilt TB110 and TB130 models, which helps narrow the application beyond a general 21-inch description. Its 8.5 by 6.5 by 0.5-inch dimensions offer a handling reference, while exact model matching remains important.

Skip it if you need a 33-inch riding-mower cover; the deawater 631-04252 is specified for select MTD Cub Cadet models.

This fits buyers replacing a hinged plug on a compatible 21-inch MTD or Troy-Bilt walk-behind mower. Use the detailed model and part-number list to narrow fit; the listing does not describe a riding-deck cover.

#2 · Best Included Hardware

2. Haiouus Hinged Mulching Plug

• Weight: 16 oz

Best for: MTD 21-inch mower replacement.

Why it ranks #2: This 987-02516A replacement plug lists MTD compatibility and comes with a spring, pin, and hinge, useful for matching assemblies.

A hinged design with the spring, pin and hinge included gives this 987-02516A plug its practical edge: it replaces a specific MTD-style mulching assembly on compatible 21-inch mowers. Its listed replacement numbers also help owners match an existing part without relying on the product name alone.

The 987-02516A identification, along with replacement numbers 687-02516 and 98702516, gives owners several reference points when matching a worn plug. The supplied spring, pin and hinge make this an assembly rather than a plug-only listing, supporting a more complete replacement workflow. Compatibility names MTD models such as 11A-BBL765 and 12A-ABE7, but the listing cautions that fit varies by mower model and manufacturing year, so model-level matching matters before installation.

Skip it if you need a chute deflector bracket in the same package; this listing says that bracket is not included.

Choose it if your compatible 21-inch mower uses the listed MTD replacement numbers and you want the spring, pin and hinge together. Check the exact model and manufacturing year, since compatibility is not universal.

#3 · OEM Tractor Pick

3. Husqvarna 46-Inch Mulch Cover

• Weight: 1.2 lb

Best for: Husqvarna 46-inch deck replacement.

Why it ranks #3: This genuine OEM 532406581 part is identified as a 46-inch deck mulch cover, with related 46-inch mulch-kit applications listed.

A genuine Husqvarna OEM identification makes this 532406581 mulch cover a direct candidate for owners referencing that part number on a 46-inch tractor deck. The listing also connects it with a 46-inch mulch kit application, helping buyers relate the cover to a broader mower setup.

The 532406581 part number and the supplied reference to a 46-inch mulch kit give owners concrete identifiers to compare with a manual or existing assembly. Its plastic construction keeps the listed material straightforward, and manual operation means there is no powered operating mechanism to manage. The product description points owners to the manual for correct part identification and installation, making that check an important part of the replacement process rather than an optional detail.

Skip it if you need a cover with mounting hardware explicitly included; C-Tzu MK46 lists mounting hardware in its title.

Consider this for a Husqvarna tractor owner whose manual identifies 532406581 and a 46-inch mulch-cover application. The manual remains important for confirming the correct part number and installation for the specific mower.

#4 · Genuine 42-Inch

4. Husqvarna 42-Inch Mulching Cover

• Weight: 4.54 g

Best for: AYP 42-inch deck owners.

Why it ranks #4: The genuine OEM AYP cover replaces 136420 and related numbers and lists compatibility with several Craftsman 917 models.

Genuine OEM AYP identity is the central advantage of this Husqvarna mulching cover, which replaces several earlier part numbers for compatible 42-inch mower decks. Its broad list of supported AYP-associated brands gives owners a useful route to identify a replacement across Craftsman, Husqvarna and other named equipment lines.

The cover replaces 134079, 198383, 136420 and 954040501, giving buyers multiple ways to cross-reference the part already specified for their mower. Its 42-inch deck designation narrows the intended application, while the listed Craftsman, Husqvarna, Poulan Pro, Poulan, Weed Eater, Roper, Sears, Rally, EHP and Yard Pro associations provide brand-level context. The dimensions are 6 by 5 by 17 inches, a helpful reference when handling or storing the cover.

Skip it if you have a mower deck outside the stated 42-inch application; the deawater 631-04252 is listed for specific 33-inch MTD Cub Cadet models.

This suits owners of compatible AYP-associated 42-inch mowers seeking an OEM replacement with several cross-reference numbers. Use the mower’s exact model and existing part number to verify that the deck application matches.

#5 · 33-Inch Deck Pick

5. deawater 33-Inch Mulch Cover

• Weight: 6.7 oz
• Dimensions: 5 x 3 x 6 in

Best for: Cub Cadet 33-inch mower fit.

Why it ranks #5: Its 631-04252 cover is designed for listed MTD Cub Cadet CC760, CC800, CC760ES, CC933, 833Em, and DW33 models.

A stated 33-inch size and compatibility with named MTD Cub Cadet models make this cover a focused option for owners of CC760, CC800, CC760ES, CC933, 833Em or DW33 2022 mowers. It is intended to keep clippings under the deck for mulching.

The direct-replacement number 631-04252 gives buyers a specific reference for matching the cover, while the listed model names narrow the mower fit to particular MTD Cub Cadet machines. Its 33-inch cover specification suits that stated deck context, and the described clipping-recycling function returns grass to the lawn as natural fertilizer. The listing also links keeping clippings beneath the deck with finer mulching, making this relevant to owners seeking that mowing workflow rather than side discharge.

Skip it if you own a 42-inch John Deere deck; the usvehj GY00115 cover lists John Deere 42-inch mower applications.

A sensible match for owners of the named MTD Cub Cadet models who want clippings managed beneath a 33-inch deck. Confirm the mower model against the listed application before choosing this replacement.

#6

6. KUAFU Tractor Mulching Cover

• Weight: 0.35 kg

Best for: Select Cub Cadet deck owners.

Why it ranks #6: It lists select 42- and 46-inch decks and several Cub Cadet, Craftsman, and Troy-Bilt models, but excludes three-blade decks.

Compatibility across select 42- and 46-inch decks, including Cub Cadet RZT-42, XT1-LT42 and XT2-LX42 mowers from 2012 onward, distinguishes this KUAFU cover. It also names Craftsman T2100 and Troy-Bilt TB46, giving those owners specific starting points for checking fit.

The listed replacement numbers—among them 19A30046100, 19A30047100 and 631-05195A—offer useful cross-references when identifying the required assembly. Polypropylene construction is described as impact-resistant, abrasion-resistant and tough, traits relevant to a mower-deck component exposed to routine use. The fit information covers select 42- and 46-inch decks but expressly excludes three-blade mower decks, so checking blade configuration is an essential step before ordering or installation.

Skip it if you have a three-blade deck; the Husqvarna 532406581 listing identifies a 46-inch tractor-deck mulch cover without that exclusion.

Choose this for a listed select Cub Cadet, Craftsman or Troy-Bilt mower with a compatible 42- or 46-inch deck. Blade count is a firm boundary: this cover is not for three-blade decks.

#7

7. Lawnmowerpartsworld 46-Inch Cover

• Dimensions: 10 x 4 x 4 in

Best for: 917-series 46-inch two-blade decks.

Why it ranks #7: This aftermarket cover targets 46-inch, two-blade decks and requires a mower model beginning with 917, making its fit criteria explicit.

The explicit requirement for a 46-inch deck with two blades and a mower model beginning with 917 makes this cover’s fit boundary unusually clear. Its aftermarket replacement description also names a wide range of AYP-associated brands, including Craftsman, Poulan and RedMax.

The 917 model-prefix requirement and two-blade deck specification give owners two concrete checks before selecting this cover. The listing identifies application part number 532406581 and describes the cover as closing the deck discharge opening to help recirculate clippings. Compatibility spans AYP, Craftsman, Jonsered, McCulloch, Poulan, Poulan Pro, RedMax, Sears and Weed Eater riding mowers, but the stated model and blade conditions remain essential.

Skip it if you have a 42-inch John Deere tractor; the usvehj GY00115 cover lists John Deere 42-inch deck applications.

This suits owners of listed-brand riding mowers whose 46-inch deck has two blades and whose model begins with 917. Check both conditions and the 532406581 application reference before selecting it.

#8

8. C-Tzu 46-Inch Mulch Cover Kit

Best for: 46-inch kit with hardware.

Why it ranks #8: The MK46 cover lists replacement numbers including 532406581 and compatibility with HU46A, MK46, and 3374, though the fit list is narrower.

Mounting hardware is explicitly included in this 46-inch mulch cover kit, a useful distinction for owners replacing a Husqvarna or Craftsman 917-series deck assembly. The MK46 designation and several related part numbers provide additional reference points for checking the required cover.

The listing names 532406581, 525405001, 53240658, 405454 and 406581, giving buyers multiple identifiers to compare with their mower documentation. Compatibility examples include HU46A, MK46 and 3374, while the title specifies a 46-inch lawn tractor deck and included mounting hardware. Metal and plastic construction are listed, and water-resistant material is claimed, which is relevant to owners considering moisture exposure around a mower deck.

Skip it if you need a cover for a 42-inch John Deere deck; the besttruck GY00115 listing covers numerous John Deere 42-inch models.

Consider this kit when a compatible 46-inch tractor deck calls for one of its listed part numbers and hardware is useful to the replacement job. Match the mower model carefully against the named applications.

9. usvehj GY00115 Mulch Cover

• Weight: 1.57 lb
• Dimensions: 16 x 6 x 5.5 in

Best for: John Deere 42-inch deck owners.

Why it ranks #9: This GY00115 replacement is for John Deere 42-inch decks and lists many 100, L100, D100, and select X-series models.

A long list of John Deere tractor families is the key advantage of this GY00115 replacement cover, spanning 100, L, D, X, LA and S-series examples. That breadth helps owners identify a candidate across several named mower lines rather than relying on deck size alone.

The stated 42-inch deck application provides the first fit reference, while the GY00115 number offers a second way to compare the cover with a mower’s existing part information. Listed examples include 102, 105, 115, 125 and 135 tractors, plus D100, X110 and LA-series machines. The 16 by 6 by 5.5-inch dimensions and 1.57-pound weight give buyers concrete handling and storage references for planning the replacement.

Skip it if you need an OEM-branded AYP 42-inch cover; the Husqvarna 954040501 listing identifies itself as a genuine OEM AYP part.

This is aimed at John Deere owners whose mower appears among the listed 42-inch applications and who can cross-check GY00115. Its model list is broad, but the deck and tractor match still govern fit.

#10

10. besttruck GY00115 Mulch Cover

• Weight: 1.46 lb
• Dimensions: 17 x 6.7 x 5.9 in

Best for: Broad John Deere 42-inch fit.

Why it ranks #10: This John Deere GY00115 cover lists 42-inch decks and numerous tractor series, but duplicates the usvehj use case without distinct fit details.

A broad GY00115 compatibility roster is the defining feature here, covering named John Deere 42-inch tractor families from LA100 and L100 through D100, X and S-series examples. That breadth helps owners check multiple mower generations and series against a single replacement reference.

The stated GY00115 replacement number gives owners a concrete cross-reference, while the 42-inch lawn mower, garden tractor, LA100, L100 and 100 Series descriptions establish the deck context. Model examples include 102, 105, 115, D100, X110, LA100 and S240, so buyers can compare a specific tractor rather than infer compatibility from brand alone. The 17 by 6.7 by 5.9-inch dimensions and 1.46-pound weight also inform handling and storage.

Skip it if you need a cover for a 46-inch tractor deck; the C-Tzu MK46 listing is specifically for a 46-inch deck kit.

This is for John Deere owners with a listed 42-inch tractor application who want to cross-check by GY00115. The extensive model roster helps, but the 42-inch deck boundary remains central to fit.
