Nothing ruins a fresh spring cleanup like ragged, torn grass tips that turn yellow weeks after mowing. If your lawn looks shredded or you notice brown dieback on the blades, the culprit is often a dull or incompatible mower blade grass setup. You do not need a new mower to fix this; you just need the right replacement edge. Many homeowners discover that swapping in a sharper, properly balanced blade restores that clean cut quality almost immediately. This prevents the unsightly browning that makes a yard look neglected. The right choice depends heavily on your specific deck size and mowing style.
We analyzed the specifications of these seven options, focusing on steel gauge, center hole geometry, and lift profiles. Whether you own a battery-electric unit or a gas-powered tractor, matching the center hole and blade length is critical. A mismatched blade causes severe deck vibration and can strip your spindle mount splines. We looked at manufacturer claims regarding heat treatment and powder-coating durability to help you avoid rust seizing. For example, the process of sharpening is easier with high-quality steel that holds an edge longer. This careful review helps you select a blade that reduces engine bogging in tall grass and ensures a consistent cut across your entire lawn area.
Pros
- Exact OEM fit for the specified Greenworks 16-inch brushless mower.
- Durable one-piece steel construction resists warping and cracking.
- Sharp cutting edge provides a clean, uniform finish on grass.
- Lightweight enough to maintain good mower balance and reduce vibration.
Cons
- Only fits the specific Greenworks 16-inch brushless mower (2540802), so it won't work on other models.
- No included hardware or installation tools, so you'll need to reuse the original bolt or buy a separate blade removal kit.
- Limited availability if your local store doesn't stock this niche model number, but online shopping covers that.
This Greenworks replacement blade is made for the 16-inch brushless mower, specifically the model numbered 2540802. It's a simple, direct replacement part that keeps your mower cutting like it did out of the box. The blade measures 15.75 inches from tip to tip, matching the factory dimensions, so you don't have to worry about fitment issues.
The best home for this blade is in your garage or shed if you own that exact Greenworks mower. Homeowners with a small to mid-sized lawn will get the most use out of it. It's also a handy spare to keep around so you can swap out a dull blade during the mowing season without downtime.
Performance-wise, the one-piece steel forging gives the blade plenty of rigidity. It cuts through normal grass without bogging down, and the edge stays sharp through multiple uses. Because it's balanced to the mower deck, you won't feel excessive vibration when you're mowing, which is good for both your arms and the mower's spindle.
Build quality is solid for the price. The single-piece steel body resists bending and chipping, and at just over half a pound, it doesn't add unnecessary weight to the mower. Installing it is a doable DIY job, just make sure you disconnect the spark plug or remove the battery before you reach under the deck.
The only real limitation is that it only fits the 16-inch brushless model, so it's not a universal blade. But if you own that specific mower, this is a reliable replacement that restores a clean, even cut. It's a practical choice for anyone who wants to extend the life of their mower without spending big money.
Blade Length: 15.75 inches
Blade Width: 1.97 inches
Blade Height: 0.71 inches
Weight: 0.5 pounds
Color: Green
Material: One-piece steel
Compatible Models: Greenworks 16-inch brushless mower (2540802)
Use this replacement blade when your original Greenworks blade gets dull from regular mowing, or if it becomes nicked after hitting a rock or root. It's ideal for homeowners who maintain their own lawn and want the mower to keep performing at a high level. Since it's sized exactly for the 16-inch brushless mower, you can swap it out in minutes and get back to cutting with confidence.
It also works well as a backup blade to keep on the shelf. If you mow weekly during the growing season, having a fresh blade ready means you never have to push through a dull cut. For anyone who owns a Greenworks 16-inch brushless mower, this is the straightforward replacement part you'll want.
Pros
- Restores sharp cutting performance with heat-treated steel
- Precise fit for Greenworks 25302 mower
- Easy to install and remove for maintenance
- Affordable solution compared to replacing the mower
- Sturdy build that handles typical yard debris
Cons
- Only compatible with specific Greenworks model (25302)
- Blade length is shorter than deck size, which may limit cutting width
- May need periodic sharpening or replacement depending on usage
These Greenworks replacement blades are a practical solution for anyone who owns the Greenworks 20-inch Twin Force mower (model 25302). Rather than replacing the entire mower when blades dull, you can simply swap in this set of heat-treated steel blades. The set includes one right and one left blade, designed to work together for balanced cutting.
This product is best suited for homeowners who already use the Greenworks 25302 mower and want to maintain its cutting performance. It's also a good option for budget-conscious shoppers who prefer to repair rather than replace equipment. The blades are intended for standard lawn mowing tasks around suburban yards, small properties, or even apartment complexes with modest grass areas.
According to the product specifications, the blades are made from heat-treated steel, which is known for holding a sharp edge longer than untreated steel. Each blade measures 9.5 inches in length, and the set is designed to fit the 20-inch deck. The actual blade length is about 1 inch shorter than the deck size to allow for proper clearance between the blade tip and the deck edge. This design helps prevent damage to the deck and ensures safe operation.
Installation is straightforward, as the blades are easily removable for sharpening or replacement. Many users find that swapping blades takes only a few minutes with basic tools. The blades are compatible only with the Greenworks 25302 model, so it's important to verify your mower model before purchasing. The product description does not mention any additional accessories or tools included, so you may need to use your own wrench for installation.
One realistic limitation is that these blades are not universal; they won't fit other mower brands or models. Also, because the blade length is slightly shorter than the deck, some users might notice a slightly reduced cutting width compared to the full deck size. However, this is a standard design feature for clearance and safety. For routine grass cutting, the performance should be satisfactory for maintaining a neat lawn.
Overall, these Greenworks replacement blades are a reliable and affordable maintenance option for owners of the 25302 mower. They help extend the life of your equipment and keep your lawn looking sharp. If you're looking for a simple way to restore cutting efficiency without a major investment, this set is a practical choice.
Pros
- Sharp out of the box - cuts cleanly on the first pass without needing to sharpen.
- Fits a wide range of popular mower brands and models, reducing guesswork.
- Solid build quality from a US-based manufacturer with a reputation for reliable parts.
- Mulches grass into fine particles that decompose quickly, reducing thatch buildup.
- Very affordable compared to OEM blades, especially for the performance you get.
Cons
- The powder coating may flake off initially, which is normal but can be messy.
- Not compatible with all 21-inch mowers - always verify your OEM part number before ordering.
- Some users report that the blade is slightly thinner than OEM, though it still holds up well under normal use.
The MaxPower 331528B is a replacement mulching blade designed for many 21-inch cut walk-behind mowers from MTD, Cub Cadet, Troy-Bilt, and Craftsman. If you've got a push mower that uses a bow tie center hole pattern with a 5/16-inch hole and 2.5-inch spacing, this blade is likely a direct drop-in. It replaces a long list of OEM numbers including 742-0741, 942-0741, and Craftsman's CMXGZAM100067, so compatibility is broad. This isn't a power tool in the traditional sense, but it's a critical component for anyone maintaining a lawn mower.
This blade is best suited for homeowners, DIYers, and weekend warriors who want to keep their lawn looking sharp without spending a fortune. It's also a solid pick for rental property owners or small landscaping crews who need a reliable, cost-effective replacement for a fleet of mowers. The mulching design chops grass clippings into fine pieces that settle into the turf, returning nutrients to the soil. That means less bagging and a healthier lawn overall.
In real-world use, the blade comes factory-sharpened and coated with a protective powder. The first cut will strip that coating away, revealing a keen edge that slices through grass cleanly. Users report a smooth, even cut with minimal tearing, which reduces stress on the grass and helps prevent browning. The heat-treated steel holds its edge well through a full season of weekly mowing, though you may want to touch it up with a file if you hit rocks or roots. Installation is straightforward: remove the center bolt, swap blades, and torque it back down. A block of wood wedged between the blade and the deck makes the job easier.
Build quality is solid for an aftermarket blade. MaxPower manufactures these in the USA (Glennville, GA and Phoenix, AZ) using a heat-treat process that meets or exceeds OEM specs. The steel feels appropriately stiff, and the bow tie center hole fits snugly on the spindle without wobble. One minor annoyance: the powder coating can flake off during the first few cuts, leaving little black specks on your lawn. That's cosmetic and harmless, but worth noting. Also, because this is a universal replacement, you absolutely must check your mower's OEM part number before buying. The listing includes a huge list of compatible models, but a mismatch could mean the blade doesn't fit or spins off-balance.
Overall, the MaxPower 331528B is a smart buy for anyone needing a reliable mulching blade at a budget-friendly price. It cuts well, fits a wide range of mowers, and is built to last. The only real drawback is the need to verify compatibility, but that's true for any universal blade. If you're tired of paying OEM prices for the same performance, this is a great alternative. Just double-check your part number, and you'll be back to mowing in no time.

Pros
- Noticeably better bagging than standard blades, especially in thick grass
- Sharp out of the box and holds its edge through several mows
- Solid steel build that resists bending or chipping on hidden debris
- Easy to install with common tools and no modifications needed
Cons
- Not designed for mulching – if you mulch, you're better off with a dedicated mulching blade
- Only fits specific EGO 21" mower models, so verify compatibility before buying
- May need occasional sharpening more often if you mow over tough terrain or sandy soil
If you own an EGO Power+ 21-inch mower and you frequently use the bagging function, swapping to the AB2101 high-lift blade is one of the simplest upgrades you can make. This blade is designed from the ground up to pull grass clippings up off the deck and into the catcher, reducing the need to go over the same area twice. It's a genuine EGO part, so you know the fit and balance are dialed in right from the factory.
This blade is best suited for homeowners and DIY landscapers who prioritize bagging performance. If you like a clean, manicured look without clippings left on the lawn, this blade delivers. The high-lift design creates more airflow, which helps keep the bag full and the cut consistent. On thick or slightly damp grass, you'll notice fewer plugging issues compared to a standard blade.
In real-world use, the AB2101 cuts cleanly and efficiently. The factory-sharpened edge makes a noticeable difference right out of the package – your first mow will have crisp edges on each grass blade. The blade itself is made from robust alloy steel, so it holds up well to hidden rocks or sticks without bending. Installation is straightforward: tip the mower, support the blade, remove the old one, and bolt this one on. No special tools are needed.
That said, this blade is not meant for mulching. If you prefer to leave clippings on the lawn for nutrients, you'll want a mulching blade or plug instead. Also, the high-lift design can create more noise and vibration than a flat blade, though it's within normal range for a cordless mower. And because it's specific to EGO 21-inch models, double-check your mower's model number before buying.
Overall, the EGO Power+ AB2101 is a solid choice if you bag your clippings and want maximum efficiency from your mower. It's well-built, easy to install, and makes a real difference in how full the bag gets. For anyone who prefers a tidy lawn without leftover clumps, this blade is well worth the investment.

This blade is ideal for owners of compatible EGO 21-inch mowers who regularly bag their grass clippings. It excels during spring and fall when grass grows fast and thick. It's also a great choice for tall fescue or Bermuda lawns where clippings tend to clump. If you bag because you dislike thatch buildup or want a clean lawn for curb appeal, this blade will make the job easier and faster.
Pros
- Solid one-piece steel construction for durability and consistent cutting performance.
- Exact fit for several Greenworks 16-inch mower models, so no guesswork during installation.
- Lightweight at just over half a pound, making it easy to handle and swap out.
- Affordable replacement cost compared to buying a new mower just because the blade wore out.
Cons

- Some users may find the blade requires periodic sharpening after heavy use on tough lawns.
- No additional accessories or hardware included, so you'll need to reuse existing bolts or purchase separately.
If you own a Greenworks 16-inch corded or cordless mower, the replacement blade under model 29512 is a straightforward upgrade that keeps your mower cutting like new. This blade is made from a single piece of alloy steel, which means there are no weak weld points that could fail over time. The forging process produces a rigid, durable edge that holds up well against grass, weeds, and even light debris. For homeowners who rely on their electric mower for weekly maintenance, this blade offers a clean, even cut without leaving ragged edges that can brown out.
The installation process is simple. You remove the old blade, line up the center hole, and bolt this one in place. The 15.75-inch length matches the factory specification, so your mower's cutting deck will operate at peak efficiency. Because it's designed specifically for Greenworks 16-inch models 25322 and 25242 (and many other 16-inch electric mowers), you won't have to worry about balance issues or poor fit. Just make sure you secure it with the proper torque and your mower will be ready to go.
In real-world use, this blade delivers consistent performance across different grass types and moisture levels. It does a good job mulching clippings and doesn't clog easily, thanks to its sturdy shape and sharpened edges. The one-piece steel construction also helps reduce vibration compared to blades with welded tips, which means less fatigue on your hands and arms during longer sessions. It's not the most aggressive blade on the market, but for a typical suburban lawn it's more than adequate.
Build quality is solid. The alloy steel resists bending if you hit a hidden rock or root, and the finish resists rust better than some cheaper alternatives. That said, like any mower blade, it will eventually need sharpening. If you mow frequently over tough grass or gravel, plan to touch it up with a file or grinder every few months. The lightweight design (just under 0.7 pounds) makes the blade easy to handle during maintenance, and it stores compactly in your workshop or garage.
One limitation is that it's not a universal blade. It only fits 16-inch mowers with the specific center hole pattern. Also, the package does not include new bolts or washers, so you'll need to reuse the original hardware or buy replacements if they're worn. For the price, this blade offers excellent value for DIY homeowners who want to extend the life of their Greenworks mower without spending on a new machine. It's a practical, reliable choice that gets the job done neatly.

This blade is best suited for homeowners who own a compatible YARDMAX mower and need a direct replacement to maintain a healthy, well-groomed lawn. It is not a universal blade, so make sure your mower model matches before purchasing.
In real-world use, this blade delivers clean, even cuts thanks to its durable steel construction. It holds its edge reasonably well through several mowing sessions, though you may need to sharpen it periodically depending on lawn conditions and debris. The lightweight design (2 pounds) makes installation simple, even for those who are not mechanically inclined. Simply remove the old blade, bolt this one on, and you are back to mowing.
Build quality is solid for the price point. The steel feels sturdy and resistant to bending or warping under normal use. It is not a premium aftermarket blade, but it performs as expected for a budget-friendly replacement. The fit is precise, with no wobble or vibration issues reported by users. That said, it lacks features like mulching capabilities or a high-lift design, so it is best for basic side-discharge or bagging setups.
One realistic drawback is its limited compatibility. If you own a different brand or a different deck size, this blade will not work. Additionally, some users might prefer a blade with a specialized cutting edge or coating for longer life. However, for the price, this is a reliable way to restore cutting performance without overspending.
Overall, the YARDMAX 22 in. Replacement Blade is a practical choice for YARDMAX mower owners who want a no-fuss replacement. It offers good value, easy installation, and dependable cutting for regular lawn maintenance. If you need a basic blade that gets the job done, this is it.

Pros
- Genuine OEM part guarantees compatibility and fit for specified Greenworks 17-inch mowers
- Heat-treated steel offers good durability and edge retention for regular mowing
- Simple installation process makes it easy for homeowners to replace worn blades
- Affordable price point compared to dealer service or generic alternatives

If you own a Greenworks 17-inch mower and the blade has seen better days, this genuine replacement part is exactly what you need. Designed as an OEM component, it matches the original blade specifications for models like MO40B411, MO40B01, MO48B2210, and MO10B00. That means no guesswork when it comes to fitment - just a straightforward swap to get your mower cutting like new again.
This blade is made from heat-treated steel, which gives it the hardness to hold an edge through multiple mowing sessions. For homeowners with small to medium lawns, this translates to consistent cutting performance on grass that's not overly thick or wet. The blade length is intentionally about an inch shorter than the deck size, a design choice that ensures proper clearance between the blade tip and the deck edge. This helps prevent contact and reduces the risk of damage during operation.
Installation is straightforward for anyone comfortable with basic tools. You'll need to remove the old blade, clean the mounting area, and attach the new one following the mower's manual. Many users find this a quick task that can be done in under 15 minutes. Having a sharp blade is key to a clean cut - it reduces tearing and helps your lawn look healthier after each mow.
One thing to keep in mind is that this blade is a standard replacement, not a specialized mulching or high-lift blade. If you primarily mulch leaves or bag clippings, you might want to check if a different blade style suits your needs better. However, for general grass cutting, this OEM blade delivers the performance the mower was designed for.
Durability is solid for typical residential use. The heat-treated steel resists bending and holds up well against small debris like twigs or rocks, though you should always inspect the blade after hitting anything hard. Regular sharpening every season will extend its life and maintain cutting quality. Overall, this is a reliable, no-fuss replacement part for Greenworks 17-inch mower owners who want to keep their equipment running efficiently without overcomplicating things.
Frequently Asked Questions
What is the difference between high-lift and mulching blades?
High-lift blades create strong airflow for bagging, while mulching blades chop clippings fine for soil return. High-lift designs use a pronounced wing profile to generate suction for the chute. Mulching blades feature serrations that pulverize grass into micro-clippings for better dispersal.
How do I match the center hole to my mower deck?
Check your old blade for 5-point, 6-point, or bow-tie patterns before buying. A mismatched center hole prevents proper spindle fitment and causes dangerous vibration. Always measure the outer hole spacing and diameter to ensure the new blade mounts securely without stripping the bolt threads.
Are these blades compatible with battery-electric lawn mowers?
Yes, several listed options are designed specifically for electric and cordless units. These blades often use thinner kerf steel to reduce drag on the motor. This helps maintain RPMs and prevents the battery from draining too quickly during heavy mowing sessions in thick turf.
When should I replace a blade instead of sharpening it?
Replace the blade if it is bent, cracked, or has deep nicks from rocks. Sharpening works for dull edges, but structural damage compromises balance and safety. You can learn more about maintenance in our sharpening guide to decide if your current blade is salvageable or needs replacement.
Does blade thickness affect cutting performance in sandy soil?
Thicker, hardened steel blades resist erosion and dulling better in abrasive sandy conditions. Thin blades may wear down quickly, leading to torn grass tips. Choosing a blade with a robust steel gauge helps maintain edge sharpness and prevents rapid degradation from constant contact with gritty soil particles.
