5 Best Lawn Mower Replacement Blades (October 2026)
The best replacement blades for lawn mowers include the EGO POWER+ 21" Blade for Electric Lawn for 3-in-1 mowing, the Apeixoto 3PCS Z248F 48 Inch Mower Blades for compatible 48-inch decks, and the Oregon 6PK USA Mower Mulching Blades for listed 61-inch mulching setups.
On this page (6 sections)
The best lawn mower blades match your exact mower model, deck and cutting setup. The EGO POWER+ blade offers three discharge options for select 21-inch mowers, while the other choices fit specific riding and commercial mower applications.
A blade that matches the deck width can still be wrong for the spindle or mower model. Check the model number, old blade number, length and center hole shape before buying replacement blades.

How we chose these lawn mower blades
The right replacement blade needs to fit first, then suit how you handle clippings. We compared the listed mower applications, blade dimensions, cutting styles and replacement numbers.
That means these are model-specific picks, not universal blades. Some details, such as a blade’s dimensions or center hole, are only given for certain options, so confirm those against your mower before ordering.
Compare lawn mower blades by fit and cutting style
Use the mower model and existing blade number as your first checks. The deck width and desired discharge style help narrow the choices after fit is confirmed.

The best lawn mower replacement blades for different mowers
The EGO option supports three cutting modes on compatible walk-behind mowers, while the remaining picks cover specified riding and commercial deck applications. For access during riding mower blade work, see lawn mower lift tables.
Start with the exact mower fit, then choose a set size and blade style that suits your setup.
EGO POWER+ 21" Blade for Electric Lawn: Best for 3-in-1 mowing
- For select EGO 21-inch mowers
- Mulching, bagging and side discharge
- Factory-sharpened steel
The 3-in-1 design supports mulching, bagging and side discharge. Check your mower model before choosing this blade.
Pros
- Three discharge options
- Designed for specific EGO models
- Genuine EGO part
Cons
- Fit is limited to listed EGO models
- Not a universal 21-inch blade
The EGO POWER+ blade is the most flexible choice here for mulching, bagging or side discharge. EGO describes it as a 3-in-1 blade for its compatible electric mower models.
Its fit list includes LM2101, LM2100, LM2102SP, LM2100SP and LM2142SP. The product title and description refer to a 21-inch mower, while the description also calls it a fresh blade for a 20.5-inch mower, so check the manual and existing part number before you buy.
This factory-sharpened steel blade is a genuine EGO part. The brand says a clean cut can promote lawn health, but the result also depends on a sharp edge, suitable mowing conditions and the mower’s setup.
Choose this blade if you have a compatible EGO mower and want to switch between mulching, bagging and side discharge. If you have a different brand, don’t rely on the 21-inch size alone to establish fit.
Apeixoto 3PCS Z248F 48 Inch Mower Blades: Best for compatible 48-inch decks
- Set of 3 blades
- For listed compatible 48-inch decks
- 16-5/8-inch length
- 5-star center hole
This three-blade set is for specified Husqvarna, Poulan and Craftsman 48-inch deck models. Match the mower and replacement number before ordering.
Pros
- Three-blade set
- Fitment list covers several mower lines
- Replacement numbers are provided
Cons
- Compatibility depends on exact mower and deck
- Center hole shape needs to match
Apeixoto’s three-blade set suits a compatible 48-inch riding mower deck. Its fit list names select Husqvarna and Poulan models, as well as Craftsman GT5000.
Each blade measures 16-5/8 inches long and 2-1/2 inches wide, with a 5-star center hole. The stated replacement numbers include 173920, 180054, PP24005 and 532180054, along with additional numbers in the compatibility details.
The range of listed mower models makes it especially important to check the exact model and deck. A 48-inch deck by itself does not confirm that the blade matches your mower’s spindle or cutting setup.
Choose the set when your mower appears in the fitment details and the replacement number matches. The product information suggests wearing gloves during installation, and your mower manual should guide safe blade handling.
Oregon 6PK USA Mower Mulching Blades: Best for listed 61-inch mulching setups
- Six-blade pack
- Mulching blades
- 21-inch length
- 5/8-inch center hole
This six-pack is aimed at listed commercial mower applications, including certain Scag 61-inch decks. Verify the exact replacement number and blade setup.
Pros
- Six blades in the pack
- Mulching style
- Dimensions and center hole size are specified
Cons
- Fitment spans specific mower models
- A 61-inch deck alone does not confirm compatibility
Oregon’s six-pack is the mulching option for listed commercial mower applications, including certain Scag 61-inch setups. The stated dimensions are 21 inches long, 2.50 inches wide and 0.203 inches thick, with a 5/8-inch center hole.
The fit information includes several Scag replacement numbers, including 481708, 481712, 482787 and 482879. It also names compatible models and parts from other mower brands, so check the complete fit details against your mower’s part number.
The pack size may suit a mower that takes multiple blades or a buyer replacing a compatible set. Do not assume six blades are needed for every 61-inch deck; the deck’s blade arrangement determines the correct count.
Choose Oregon when you need this mulching style and your model or replacement number is confirmed. For a conventional replacement that isn’t listed as mulching, compare blade style and lift requirements in the mower manual before buying.
MaxPower 561149B USA MADE 3 Blade Set: Best for Bad Boy 54-inch cuts
- Three blades for 54-inch cut Bad Boy mowers
- Fits MZ Magnum
- Replaces OEM 038-0005-00
- 5/8-inch center hole
This three-blade set is made for the stated Bad Boy application and replaces OEM 038-0005-00. Check the old blade’s replacement number.
Pros
- Three-blade set
- OEM replacement number is stated
- Blade dimensions are specified
Cons
- Limited to compatible 54-inch cut mowers
- Confirm the old blade number before buying
MaxPower’s set targets Bad Boy mowers with a 54-inch cut, including the MZ Magnum. It contains three blades and replaces OEM part 038-0005-00.
Each blade is 18-3/4 inches long and 2-1/2 inches wide, with a 5/8-inch center hole. MaxPower says the blades are sharpened during manufacturing and powder-coated; the coating wears off during the first cut.
Those details make the old blade number a useful cross-check. Confirm that 038-0005-00 matches your mower before buying, because deck size alone does not verify fit.
Choose this set for the listed Bad Boy application when you want a three-blade replacement. If your mower uses a different OEM number, compare the manual and existing blade before considering it.
Ariens 6PK Genuine OEM 60" Gravely Pro-Turn: Best for Gravely OEM replacement
- Six genuine OEM Gravely blades
- Part number 09081200
- For specified 60-inch Pro-Turn applications
This six-pack is a genuine Gravely OEM part for listed Pro-Turn and other applications. Use the model manual or existing part number to confirm fit.
Pros
- Genuine OEM Gravely part
- Six-blade pack
- Part number is stated
Cons
- Fitment is limited to specified applications
- Blade dimensions are not stated here
Ariens is the genuine OEM choice for specified Gravely 60-inch mower applications. This six-pack uses Gravely part number 09081200 and is listed for Pro-Turn 100, 200 and 600, Pro-Walk and Pro-Stance models.
An OEM blade can be a straightforward match when your manual or existing part carries the same number. The product information does not give blade dimensions, so use part number and model compatibility to check fit rather than estimating from deck width.
Choose Ariens if you need the specified Gravely part and your mower is included in the applicable fit details. If you have another Gravely model or a different deck setup, confirm the number first.
What should you check before buying a blade for a lawn mower?
Check the mower model and replacement number before comparing blade style. Those details help prevent a blade with the wrong length, hole shape or fit from reaching your mower.
Does deck width tell you which new lawn mower blade to buy?
No. Deck width describes the mower’s cutting width, not the exact blade size or spindle connection.
A 48-inch deck, for example, can use several blades, and the compatible set depends on the mower model and blade arrangement.
Use the mower manual or the old blade’s part number to narrow the choice. If the replacement details also give blade length and center hole shape, compare those measurements with the blade you removed.
How do you compare blade length and center hole?
Measure the old blade from tip to tip and note the center hole shape and size. A blade with the wrong length or mounting hole may not fit or operate as intended.
The picks here show why both details matter: some specify blade dimensions and hole size, while the Ariens option centers on its OEM part number. Follow the manual’s fit requirements when the old blade is damaged or its markings are hard to read.
Should you choose a mulching, bagging or discharge blade?
Choose a blade style that matches your deck and how you handle grass clippings. A 3-in-1 blade can support several methods when the mower is designed for it, while other mower setups call for a specific blade style.
The EGO blade is described as supporting mulching, bagging and side discharge on compatible models. Oregon’s option is identified as a mulching blade, so confirm that style suits your mower before swapping it in.
How do you install replacement blades safely?
Use the mower manual for removal and installation steps, and keep the mower powered off while you work. Before reinstalling a sharpened blade, check it with a lawn mower blade balancer.
A blade is sharp, so wear gloves and secure the mower as the manual directs.
For removal steps, see How to Remove a Lawn Mower Blade?. If you’re replacing the blade and need the full process, follow How to Change Lawn Mower Blades?.
After installation, confirm the blade is attached as specified and that it can move freely without contacting the deck. When sharpening an undamaged blade instead, check how often you should sharpen lawn mower blades and read how to sharpen lawn mower blades.
Which lawn mower blade should you choose?
Choose the EGO blade if you have a compatible 21-inch mower and want mulching, bagging and side discharge. Pick Apeixoto, Oregon, MaxPower or Ariens only when your mower model and part number match the stated application.
For brand-specific comparisons, see our guides to best Ryobi lawn mower blades and best Toro lawn mower blades. The safest buying rule is simple: confirm the model and replacement number first, then choose the cutting style and pack size that fit your mower.

Frequently asked questions
How do I know which lawn mower blade fits?
Match the mower’s make, model, deck size and blade part number before buying a replacement. Deck width alone is not enough because blade length, center hole shape and mower setup also matter.
Check your manual or compare the replacement number on the old blade.
Are mower blades universal?
No. A blade must match the mower’s deck and spindle setup, including its length, center hole and replacement part number.
Even blades described for the same deck width can fit different models.
Verify the mower’s exact model and the blade number before installation.
What is the difference between mulching and standard blades?
Mulching blades are shaped to keep clippings moving under the deck so they can be cut into smaller pieces. Other blade styles are designed around lifting and discharging clippings into a bag or out a side chute.
Choose a style that matches your deck and how you handle clippings.
Can I use a mulching blade for bagging?
Some blades support both mulching and bagging, but that depends on the blade and mower design. EGO describes its 21-inch blade as supporting mulching, bagging and side discharge on compatible models.
Confirm the mower manufacturer’s guidance before changing blade style.
When should I replace a lawn mower blade?
Replace a blade when it is damaged, badly worn or cannot be sharpened to a usable edge. A bent or cracked blade needs replacement rather than sharpening.
After removal, inspect the cutting edges and blade body, and follow your mower manual for safe handling and installation.
