Mulching results depend on more than blade shape: a replacement part must also match your mower’s deck, center-hole pattern, and model. This guide to the best mulching mower options compares replacement blades and a tractor mulching cover, helping you narrow choices by mower fit and whether you want to mulch, bag, or discharge clippings.
These products are mower parts, not complete mowers. Check your mower’s full model number, deck size, and current part number before ordering. For more lawn equipment guides, visit our Lawn Mowers category.

The Best Mulching Mower Parts by Use Case
Best for EGO Select Cut Mowers: UDC Parts AB2101D Mulching Blades Set Replacement
The Lawn & Garden category includes equipment guides, but this pick serves a specific need: replacing the two blades in compatible EGO Power+ 21-inch Select Cut mowers. The listing identifies the upper and lower blades as replacements for AB2101D and specifies compatibility with models including LM2130, LM2133, LM2135SP, LM2150SP, and LM2156SP. The two-blade set is intended for mulching and bagging, making it relevant if you use either clipping method.
Reasons to buy:
- Includes upper and lower blades for the Select Cut multi-blade system.
- Listing specifies compatibility with several EGO Power+ 21-inch mower models.
- Made from high-strength steel and supplied pre-sharpened, according to the listing.
Reasons to avoid:
- Fit is limited to listed models and the matching 21-inch system.
- Confirm your existing blade part number and mower model before purchase.
Skip it if your mower is not a compatible EGO Select Cut model or uses a different blade arrangement.
Best for Compatible Lawn Tractors: KUAFU Tractor Mulching Cover Compatible
The KUAFU Tractor Mulching Cover Compatible is a deck accessory rather than a replacement cutting blade. Its listing names select Cub Cadet 42- and 46-inch deck models, Craftsman T2100, and Troy-Bilt TB46, with specified replacement numbers including 631-05195A. A cover closes the discharge opening for mulching, so it may suit tractor owners who want to leave clippings on the lawn rather than collect them.
Reasons to buy:
- Fits several listed tractor families and replacement part numbers.
- PP construction is specified in the listing.
- Uses a bolt-on installation, although adjustments may be needed.
Reasons to avoid:
- Does not fit three-blade mower decks, according to the listing.
- Installation accessories and instructions are not included.
Skip it if your deck is not among the listed compatible models or you need a replacement blade rather than a discharge cover.

The listing also names select Poulan, Dixon, Jonsered, and RedMax models.

Reasons to buy:
- Lists specific OEM replacement numbers and compatible mower models.
- Pre-sharpened cutting edge is specified by the manufacturer.
- Designed to recut clippings beneath the deck for mulching.
Reasons to avoid:
- The five-point star center hole and 21-3/4-inch blade length must match your mower.
- Compatibility is limited to select models, not every 22-inch mower.
Skip it if your mower uses a different center-hole pattern, blade length, or OEM part number.

The listing gives GY20850, GX22151, and AM141033 as replacement numbers and names a range of lawn tractor models. Its crucial fit detail is the seven-point star center hole, so this set is suitable only when both deck size and spindle pattern match.

Also Considered
For a compatible 21-inch Troy-Bilt or MTD mower, the Hipa 942-0741A 21 inch Lawn Mower Mulching Blade lists mulching, bagging, and side discharge, but verify its bow-tie center hole and OEM number. The Maxpower 331528B USA MADE 21" Cut Mulching Blade could suit buyers seeking a single blade for listed MTD, Cub Cadet, or Troy-Bilt models, though its listing also stresses matching the current OEM number.
The Grasscool 22 inch Deck Toro Recycler Lawn Mower is listed for compatible Toro 22-inch Recycler decks, with a circular center hole and specific replacement numbers. John Deere owners with select 48-inch decks may consider the GICOOL GY20852 Mower Mulching Blades for JD 48, a three-blade set with a seven-point star mount. The Husqvarna 54-Inch Mulching Lawn Mower Blades are a three-pack for compatible Husqvarna riding mowers using the listed star mount and OEM number.
How to Choose the Best Mulching Mower Parts
Match the mower model and replacement number
Start with the mower’s full model number and the number stamped on its current blade or accessory. A broad brand match is not enough: product listings often cover only selected models, years, or deck versions. For example, the UDC Parts John Deere set lists several part numbers and notes that parts may differ even within one mower model. Compare your manual, old part, and listing before ordering.
Confirm deck size and blade dimensions
Deck size and blade length are related but not identical measurements. The Oregon blade is listed as 21-3/4 inches for a 22-inch deck, while the BCQNXX set specifies three blades for a 60-inch deck. Check the deck size, blade length, and number of blades required. A blade that is too long or intended for another deck can be incompatible even if the mower brand matches.
Check the center-hole shape and mount
The spindle connection must match the blade. Listings here specify several different designs, including a seven-point star, five-point star, bow-tie, and circle. Compare the shape and dimensions with your existing blade. Do not assume two blades fit because their lengths are close; the wrong mount can prevent secure installation.
Choose the clipping method you need
Mulching blades are shaped to cut and recut grass beneath the deck, while some listed blades also support bagging or side discharge. The Hipa and GICOOL listings describe three-in-one use, while the Oregon blade focuses on recirculating clippings for finer mulch. A deck cover serves a different role: the KUAFU cover closes a compatible tractor’s discharge opening. Check whether your mower needs a blade, a cover, or both before choosing.
Review pack quantity and installation details
Replacement quantities vary from one blade to multi-blade sets. Match the package quantity to your mower’s blade arrangement, and confirm whether the listing includes mounting hardware or instructions. The KUAFU cover listing says accessories and instructions are not included. Blade listings also describe protective paint or coating that wears away during use; follow your mower manual for installation and safe handling.
How We Compared
We compared the supplied listings by stated mower compatibility, replacement numbers, deck size, blade dimensions, center-hole pattern, pack quantity, and described mowing functions. Product descriptions also supplied construction and installation details, which we treated as manufacturer or seller claims rather than independently verified findings. The supplied product data showed no customer review text, so this guide does not rely on customer-reported experiences.
Frequently Asked Questions
Can I use any mulching blade that matches my deck size?
No. Deck size alone does not confirm fit. Match the mower model, OEM replacement number, blade length, and center-hole pattern. Check the current blade and mower documentation when listing compatibility is unclear.
What is the difference between a mulching blade and a mulching cover?
A mulching blade cuts and recuts grass beneath the mower deck. A mulching cover closes the discharge opening on a compatible mower deck. They are different parts, and a cover does not replace a blade.
Do mulching blades also work for bagging or side discharge?
Some listings describe more than one clipping method, but this varies by blade and mower. Hipa and GICOOL list mulching, bagging, and side discharge. Confirm compatibility and follow your mower’s instructions before changing the discharge setup.
Should I replace every blade on a riding mower at once?
Check your mower manual and the number of blades its deck uses. Some products here are sold as two- or three-blade sets, while others contain one blade. The correct quantity depends on the mower’s deck and replacement requirements.
Do protective coatings need to be removed before mowing?
Instructions differ by listing. Several blade descriptions say their protective coating wears away during initial use, and the Grasscool listing says not to remove its paint before use. Follow the product instructions and your mower manual, and secure the blade correctly before operating the mower.
