The best PowerSmart lawn mower replacement blade is the one that matches your mower model, deck size and mounting pattern. A close looking blade can still fail if the center hole differs.
The products below cover common sizes for everyday lawns in 13, 16, 21 and 22 inch formats. Most are made for Greenworks, YARDMAX, Yard Force, Husqvarna or Craftsman mowers, so confirm compatibility before ordering.
Start with your mower model number and the old blade. Those details give a faster and safer answer than a general search.
This guide suits owners who know their deck size and want a short list to compare. It works best for small to medium yards where fit matters more than extras.
If the blade is straight and only dull, sharpening may be enough. If the edge is worn down or damaged, replacement is clearer.
A single blade suits an immediate change, while a multi pack suits an owner who wants a spare. For a wider starting point, compare these picks with our guide to best lawn mower blades.
Keep the old blade until the new one is fitted. That lets you compare length, width and holes side by side before you tighten anything.

Which replacement blades suit different mower sizes?
The right blade depends first on the mower it fits. The Greenworks 16 in and 13 in options name exact models, while the 21 in and 22 in products need a careful model and mounting check.
Deck size helps narrow the search. It does not confirm that a blade will mount correctly or swing with proper clearance.
The 21 in group includes different brands and mounting details. Two blades can both be listed as 21 in and still suit different mowers.
The 22 in YARDMAX blade is aimed at a gas mower. A PowerSmart owner should not assume a large deck means the same fit.
Our score weighs stated specifications, compatibility details, blade type and pack size. We checked product information, but we did not test these blades on a mower.
That approach favours clear model data over vague claims. A blade with named models and measured length is easier to compare with your own mower.
Pack size also shapes the score. A 2 pack suits an owner who wants a spare, while a single blade suits a direct replacement.
Blade type matters for mulching models. A dual edge or mulching blade differs from a plain cutting blade, even when the length looks similar.
Use the score as a starting point, not final fit approval. Your mower manual and old blade remain the final reference.

Best PowerSmart lawn mower replacement blades by use
These replacement blades are listed from the highest score to the lowest. Read the compatibility details closely because a high score does not override a model mismatch.
Greenworks Replacement Lawn Mower Blade: Best for 16 in electric mowers
- Fits Greenworks 16 in mowers
- Compatible with models 25322 and 25242
- 15.75 in actual blade length
- One-piece alloy steel construction
This Greenworks blade is the strongest fit-specific choice for compatible 16 in electric mowers. Its one-piece alloy steel construction keeps the replacement simple and focused.
Pros
- Clear model compatibility
- One-piece steel construction
- 15.75 in blade length
Cons
- Limited to specified Greenworks mower models
- Single blade
The Greenworks Replacement Lawn Mower Blade is the top pick for a compatible 16 in electric mower. It fits Greenworks models 25322 and 25242, with an actual blade length of 15.75 in.
That 15.75 in measurement is a useful check. It shows the blade is slightly shorter than the 16 in deck, which is normal for tip clearance.
The one piece alloy steel construction gives a simple design for a direct replacement. One piece designs avoid extra joints and keep the shape straightforward.
This suits owners of the named models who need a like for like change. It is less suited to a mower outside that list, even if the deck size seems close.
Care is simple but important. Wipe grass from the blade after use, store it dry and check the edge before each season.
Before fitting, compare the old blade length and mounting pattern. Line up the holes without force and make sure the cutting edge faces the right way.
This is a single blade, so it suits one replacement now. It does not include a spare for a later change.
Before using it on a PowerSmart mower, compare the old blade with the mower manual. Compatibility should come from documents, not a close visual match.
YARDMAX 22 in. Replacement Blade for Gas: Best for 22 in YARDMAX gas mowers
- Fits YARDMAX 22 in gas lawn mowers
- 22.05 x 2.45 x 1.58 in package dimensions
- 2 lb item weight
Choose this replacement when your YARDMAX gas mower uses a 22 in deck and the fit is confirmed. Its narrow compatibility makes it a focused option rather than a general blade.
Pros
- Made for a stated YARDMAX 22 in gas mower
- Large deck-size match
- Clear brand fit
Cons
- Compatibility is limited to the stated mower type
- Blade measurements are not fully detailed
The YARDMAX 22 in. Replacement Blade for Gas Lawn Mowers is aimed at a YARDMAX 22 in gas lawn mower.
That makes it the largest deck size match in this group. It suits a larger lawn where a 22 in deck covers more ground per pass.
It is a focused choice for owners with that exact mower type. The fit is narrow by design, so brand and mower type matter more than general size.
The package measures 22.05 x 2.45 x 1.58 in, and the item weight is 2 lb. These details help you plan storage and handling.
Store it flat, keep the edge protected and keep it away from damp ground. A long blade also needs space in a shed or garage.
These details do not replace a check of the blade mounting shape. You still need the center hole and mounting pattern.
PowerSmart owners should treat this as a possible reference only unless their documentation confirms the same fit. A similar deck size is not proof of fit.
Compare the old blade and the manual first, then decide. For a YARDMAX owner this is a straightforward size match.
DAOLONG 21 Inch Mower Blade: Best for a 2-pack of 21 in blades
- Fits several Greenworks 21 in mower models
- High hardness quenched steel
- Heat-treated cutting edge
- 2-pack
This DAOLONG set suits owners of compatible Greenworks 21 in mowers who want two replacement blades. The 2-pack gives you a spare for a later change without switching blade sizes.
Pros
- Two blades in one pack
- 21 in cutting width
- Several named Greenworks models
Cons
- Only fits listed mower models
- A 2-pack may be more than needed for one replacement
The DAOLONG 21 Inch Mower Blade set is the strongest choice for a compatible Greenworks 21 in mower when you want 2 blades in one pack. It fits C3208101, MO40L4413, MO40L03 and MO48L4422 models.
The 2 pack gives you the blade you need now and a second one ready for the next maintenance cycle.
The blades use high hardness quenched steel and a heat treated edge. That treatment aims to keep the edge working through regular home mowing.
It is described as a rotary blade set for 21 in mowers, with 2 pieces included. Rotary format suits standard decks where the blade sweeps in a circle.
This suits owners of the listed Greenworks models who mow often. Frequent use makes a spare more worthwhile than for a mower used only a few times a year.
It is less suited to someone who needs just one blade and has no storage for a spare.
Store the spare flat and dry. Label it with the mower model so it does not get mixed up with other blades.
For a PowerSmart mower, verify the center hole and mounting points before treating this as a match. The listed Greenworks models are the confirmed fit.
Greenworks Replacement Lawn Mower Blade: Best for 13 in brushless mowers
- Fits Greenworks 13 in brushless mowers
- Fits models 2534402 and 2554102
- Alloy steel construction
- One-piece replacement
This genuine Greenworks blade is aimed at compatible 13 in brushless mowers. It is a practical match when the mower model is 2534402 or 2554102.
Pros
- Clear 13 in mower fit
- Named compatible models
- Alloy steel
Cons
- Limited to specified Greenworks models
- Single blade
The Greenworks Replacement Lawn Mower Blade for 13 in mowers is the best fit here for compatible brushless models 2534402 and 2554102. It is a genuine Greenworks replacement made from alloy steel.
A 13 in deck suits smaller yards and tighter spaces. It is a practical size for patios, narrow side yards and compact lawns.
The blade is designed for a 13 in mower deck, and the product information notes that the blade is about 1 in shorter than the deck size for clearance. That detail shows why deck size and actual blade length are not always identical.
That clearance gap is not a fault. The blade needs room to rotate without striking the deck edge.
Alloy steel construction is aimed at steady everyday use. Wipe the blade clean after mowing and let it dry before storage to limit rust.
This is a single blade option, so it suits a direct replacement. Owners who like to keep spares will need to order separately.
Choose this single blade option when your mower model matches. The named models give you a clear yes or no decision.
PowerSmart owners should compare the old blade's measurements and mounting pattern instead of relying on the 13 in size alone. A compact deck still needs the right holes and shape.
After fitting, check that the blade turns freely by hand with the mower powered down. A blade that binds or scrapes is not ready to use.
Merotec Yard Force 21-Inch 3N1 Lawn Mower: Best for Yard Force 3-in-1 mowers
- OEM part 1253556001
- Fits three Yard Force mower models
- Dual-edge mulching blade
- Stamped steel construction
This Yard Force replacement is for owners of the named 21 in 3-in-1 mowers. Its dual-edge design supports bagging, mulching and side discharge on those compatible machines.
Pros
- OEM part number is supplied
- Three named mower models
- Dual-edge mulching design
Cons
- Not a general PowerSmart fit
- Compatibility depends on the exact Yard Force model
The Merotec Yard Force 21-Inch 3N1 Lawn Mower Blade suits three named self-propelled mowers: YF22-3N1SP, YF22-3N1SP-SC and YF22-3N1SPVS-SC.
It is OEM part 1253556001 and uses stamped steel in a dual-edge mulching design. That part number gives Yard Force owners a direct way to confirm fit.
The blade measures 21 in long and 2.25 in wide, with a 1 in center hole. Compare those numbers with the old blade before you order.
Its 3-in-1 design supports bagging, mulching and side discharge on the compatible models. It is more specialized than a plain replacement blade.
Owners who switch modes will notice the design most. Airflow and clipping flow matter when you bag or mulch.
Stamped steel suits regular home use and is aimed at reduced vibration. Clean the blade after mowing so grass does not pack against the edges.
That helps keep the cut even and makes damage easier to spot. Check the exact mower model before considering it for PowerSmart equipment.
The Yard Force model list is the confirmed fit. Measure your old blade hole to see whether the 1 in center hole lines up.
This blade suits a Yard Force owner who wants a part made for that mower family. It is a poor shortcut for a different brand or model.
Chway 1Pcs 21 Inch Lawn Mower Blade: Best for checking a 21 in mulching fit
- 21 in mulching blade
- Fits listed Husqvarna and Craftsman replacement numbers
- High-strength steel
- Circle mounting pattern
This Chway blade is a 21 in mulching option for the listed Husqvarna and Craftsman replacement numbers. Check the center-hole pattern before considering it for another mower.
Pros
- 21 in mulching format
- Several replacement numbers
- High-strength steel
Cons
- Center-hole match must be checked
- Listed for Husqvarna and Craftsman numbers
The Chway 1Pcs 21 Inch Lawn Mower Blade is a mulching blade for the listed Husqvarna and Craftsman replacement numbers. It measures 21 x 2.25 x 0.15 in and uses a circle mounting pattern.
A mulching blade is shaped to cut clippings finely and return them to the lawn. That suits owners who mulch as their normal routine.
The replacement numbers include 165833, 175064, 189028, 406712, 532175064, 532165833, 532189028 and 532406712. Those numbers are the fastest way to check fit.
Chway also identifies it as a high-strength steel blade for a 21 in deck. High strength steel is aimed at regular use on the listed mower types.
The circle mounting pattern is a key detail. Even with the right length, a different center shape can stop the blade from sitting flat.
The center hole pattern matters most when comparing this blade with another 21 in option. Check it before you consider any other 21 in blade as the same.
This single blade suits an immediate replacement on a listed model. It does not include a spare, so plan ahead if you like to keep one ready.
Treat it as a possible reference for a PowerSmart mower only if the mower's mounting pattern matches exactly. Listed Husqvarna and Craftsman numbers are the confirmed fit.
After use, clean grass from both sides of the blade. A clean mulching blade cuts more evenly and is easier to inspect for damage.
How do you match a PowerSmart mower blade?
Match the replacement blade to the mower model first, then confirm the deck size and mounting pattern. If your mower takes a 14-inch blade, compare 14-inch mower blades before ordering.
The model number usually gives you a more reliable starting point than a general search for a PowerSmart lawn mower blade replacement.
Remove the battery, unplug the mower or follow the engine shutdown procedure before inspecting the blade. Block the blade so it cannot turn, wear gloves, and keep your hands away from the cutting edge.
Measure the old blade's length and width. Then compare the center hole, outer mounting holes, lift shape and direction of the cutting edge.
Do not force a blade into place when the holes do not line up. A loose or mismatched blade can create vibration and may damage the mower.
For the installation sequence, follow our guide on How to Change Lawn Mower Blades?. The guide explains the basic removal, inspection and tightening process.
Is a 21 in replacement blade right for your mower?
A 21 in blade is suitable only when the mower is designed for that blade size and mounting layout. The DAOLONG, Merotec Yard Force and Chway products all use a 21 in format, but their listed mower fits and mounting details differ.
The DAOLONG option is tied to four Greenworks models and includes 2 blades. The Merotec blade has a 1 in center hole and fits three Yard Force mower models, while the Chway blade uses a circle mounting pattern and several Husqvarna and Craftsman replacement numbers.
This comparison shows why the phrase “PowerSmart lawn mower replacement blade” needs more detail. Add your mower model and deck size to the search, then confirm the physical measurements.
Should you sharpen or replace the blade?
Sharpen a blade when the edge is dull but the metal is straight and free from serious cracks or chips. Replace it when it is bent, deeply damaged or too worn to maintain a safe edge.
That distinction saves money without taking risks. Sharpening suits a dull edge, while replacement suits a blade whose shape or strength has changed.
A dull blade tends to tear grass rather than cut it cleanly. The lawn can look rough even when the mowing height is correct.
Check along the full length of the blade, not just near the tips, before you decide. A sharp, balanced blade helps cut more evenly, since an uneven edge can add vibration.
Sharpening does not correct a blade that is the wrong size or mounted incorrectly. It cannot fix a poor fit or a loose mounting.
Replacement is the simpler choice when you are unsure about damage. A crack or bend can change how the blade behaves at speed.
Many home owners can sharpen with basic tools and a steady hand. Work in small passes and keep the edge angle consistent.
Use our guide on How to Sharpen Lawn Mower Blades? if the blade is still usable. It helps you judge whether sharpening is enough.
Clean the blade before you sharpen it. Grass and grit make it harder to see cracks or thin spots.
After sharpening, check balance by resting the blade on a dowel. A blade that tips heavily to one side may need adjustment.
Mowing conditions also shape the decision. Sandy soil, stones and thick wet grass wear an edge faster than clean, dry grass.
If the blade keeps dulling quickly, look at lawn conditions as well as the blade. Frequent sharpening may be a sign that replacement is due soon.
What are the best alternatives for other mower brands?
The best alternative depends on the mower brand and the type of blade it uses. Greenworks owners can compare the 13 in and 16 in model-specific options here, while other owners should stay with the exact model numbers in the product details.
Brand matters because mounting patterns rarely cross over without a check. A blade for one brand may share a length with another and still use different holes.
Greenworks owners have an advantage in this group. The 13 in and 16 in blades name their compatible models, so the decision is fairly clear.
YARDMAX owners have a clear 22 in gas mower option. The fit is narrow, but it is stated plainly for that mower type.
Yard Force owners can use the OEM part number for the 21 in 3-in-1 blade. That number is more reliable than a general deck size search.
Husqvarna and Craftsman owners can check the listed replacement numbers for the Chway blade. Those numbers cover the confirmed fit for that option.
Honda owners can also compare replacement Honda mower blades by exact model. Model first is the same rule across brands.
For another brand-specific comparison, see our guide to best ryobi lawn mower blades or our picks for best toro lawn mower blades. These pages show how model fit changes across brands.
Blade type is another split between brands. Mulching blades, standard cutting blades and 3-in-1 designs suit different mowing habits.
Pack size can also differ by brand and seller. A 2 pack may suit one owner, while a single blade suits another.
If your brand is not covered here, use the old blade as your guide. Do not cross brands on length alone, as the center hole and mounting shape are where most mismatches happen.
Final choice for PowerSmart lawn mower replacement blades
Choose a replacement by exact mower fit, not by deck size alone. The Greenworks 16 in blade is the highest scoring fit specific option here, while the DAOLONG 2-pack is useful when a compatible 21 in mower needs a spare.
Start with the model number on your mower. That one detail will rule out most blades quickly and leave a short list you can check properly.
For any PowerSmart lawn mower blade replacement, compare the model number, blade length, center hole and mounting pattern before ordering. If those details match, the replacement is far more likely to install correctly and cut as intended.
Keep the old blade beside the new one during fitting. If the holes do not line up without force, stop and recheck the fit.
Consider how you mow as well as what you own. A mulching blade suits a mulching routine, while a plain cutting blade suits other modes.
Think about spares too. A 2 pack suits an owner who wants the next change ready, while a single blade suits a one time fix.
If your mower is not in the named lists, do not guess. Use your manual and old blade measurements to find a blade made for your model.
A correct fit gives the mower its best chance to cut evenly. It also avoids vibration, poor clipping flow and extra work.
Order only after the check is complete. A few minutes of measuring now is cheaper than a return later.

Frequently asked questions
How do I choose a PowerSmart lawn mower replacement blade?
Match the mower model, deck size, blade length and center-hole pattern before choosing a PowerSmart lawn mower replacement blade. Deck size alone is not enough because two blades with the same stated width can use different mounting patterns.
Remove the old blade only after the mower is powered down and secured.
Can any 21 in mower blade fit a PowerSmart mower?
No. A 21 in blade may still have the wrong center hole, mounting pattern, width or shape for your PowerSmart mower.
Use the mower manual and old blade as references, then compare the exact measurements.
The 21 in size narrows the search, but it does not confirm compatibility.
What should I check before buying a replacement blade?
Check the mower model, deck size, blade length, center hole, mounting pattern and blade type. Also confirm whether you need a standard cutting blade or a mulching blade.
If any measurement is unclear, keep the old blade available and compare it with the replacement before installation.
How often should a lawn mower blade be replaced?
Replace a blade when it is bent, cracked, badly chipped, worn down or no longer cuts evenly after sharpening. The right interval depends on mowing conditions, grass thickness and contact with soil or stones.
Use our guide on How Often Should You Sharpen Lawn Mower Blades? to decide when sharpening is still suitable.
