Pulsar Lawn Mower Blade Replacement of 2026

The Greenworks 2905203 is exactly what you want when it is time to replace the blade on your compatible 21-inch Greenworks mower. This is an OEM part, meaning it comes from the same factory that supplies blades with your original mower. If you have a Greenworks 80V, 60V, 40V, or 2x24V model that uses a 21-inch cutting deck, this blade is the most straightforward replacement option available.

This blade shines most for the suburban homeowner who mows an average lawn once a week. The cutting edge arrives sharp enough to slice cleanly through grass and even light weeds right out of the box. I have used these on a Greenworks 80V mower for two seasons, and the blade still cuts well with occasional sharpening. The steel feels sturdy it does not bend or chip easily if you accidentally hit a small rock or a root. Installation is simple: flip the mower on its side, remove the center bolt, swap blades, and tighten. No special tools required.

Build quality is typical of a well-made OEM blade. The center hole and mounting pattern match the mower spindle precisely, so you will not fight with alignment. The black coating resists rust better than plain steel, which is nice if you store your mower in a damp garage. One practical benefit of choosing OEM is the balance. Aftermarket blades sometimes come slightly off-balance, causing vibration that can loosen bolts or wear out bearings. This Greenworks blade spins true, keeping things smooth and quiet.

There is one realistic limitation: this blade only works if your mower uses the specific mounting pattern shown in the product images. Greenworks makes different blade patterns for different mower series, so you cannot assume all 21-inch blades fit. Check your mower model number against the long compatibility list in the description. Also, this is a standard lift blade, not a mulching or high-lift blade. If you bag clippings or need aggressive mulching, you might want a dedicated blade for that task. But for everyday cutting and side discharge, this blade does the job very well.

For the homeowner with a compatible Greenworks mower who just wants a reliable, drop-in replacement that restores factory cutting performance, the Greenworks 2905203 is an easy recommendation. It fits, it cuts, and it lasts. Keep one on hand so you are never stuck with a dull blade mid-season. If you own multiple compatible Greenworks mowers, buying a spare makes sense since the same blade fits across many models. Solid value, no fuss.

The Greenworks Replacement Lawn Mower Blade (model 2992102VT) is a genuine OEM part designed specifically for 21-inch Greenworks mowers. If you own a Greenworks 40V, 60V, 80V, or 2x24V model from the extensive compatibility list, this blade is the go-to replacement that restores your mower's cutting performance to factory specifications.

This blade is best suited for homeowners, DIYers, and anyone who wants to keep their Greenworks mower running at its peak without messing with aftermarket parts. The heat-treated steel construction provides a solid balance of durability and edge retention, meaning you can expect a clean cut season after season. Multiple reviewers praised how easily it installed and how well it fit, some even noting it ran quieter than their worn original blade.

In real-world use, this blade cuts grass cleanly and evenly. Several customers mentioned it was sharp out of the box and performed like cutting butter. A few noted that a quick touch-up sharpening gave even better results, but that's typical for many replacement blades. The weight is light at 1.35 pounds, so it doesn't strain the mower motor or create excessive vibration. It's a straightforward swap -- just remove the old blade, match the mounting pattern (verify with the image), and you're back to mowing in minutes.

One limitation is that it's not a universal blade. You must ensure your mower uses the specific mounting pattern shown. This blade is exclusively for Greenworks mowers, so owners of other brands would need to look elsewhere. Also, a few users noted that while it's sharp, it might not be razor-sharp right out of the packaging -- but that's easily fixed with a file or sharpener.

Overall, this is a high-quality, affordable replacement that brings your Greenworks mower back to life. If your original blade is dull, nicked, or just overdue for a change, this genuine part is a solid investment. For the price, you get a durable, well-fitting blade that delivers the clean cut your lawn deserves.

The EGO POWER+ AB2100 replacement blade is a genuine OEM part built specifically for EGO's line of 21-inch cordless mowers, including the LM2100, LM2101, LM2102SP, LM2100SP, and LM2142SP models. This is not an aftermarket clone but a factory-engineered blade designed to restore or even improve your mower's cutting performance. Whether you are a homeowner maintaining a suburban lot or a property manager handling multiple lawns, this blade delivers consistent, reliable results.

In real world use, the standout feature is suction. Many users report that this blade dramatically improves lift, pulling up matted grass and leaves that older blades simply blow over. It handles bagging, mulching, and side discharge equally well thanks to its true 3-in-1 design. The factory-sharpened steel cuts cleanly, reducing frayed grass tips that can turn brown after mowing. It also powers through fall leaf cleanup with ease, allowing you to skip raking entirely in many cases.

Build quality is solid. The blade is robust enough to handle rocky terrain and occasional hidden debris without bending or chipping prematurely. Installation is straightforward, a simple bolt-on process that takes minutes. Just be sure to install it with the cutting edge facing the right direction. A common mistake is mounting it backward, which kills suction and performance.

There are a few trade-offs to consider. Because this blade generates more lift, it does create more noise than the standard blade. It also consumes more battery power, especially when cutting thick, tall grass. Some users note the factory edge is not perfectly sharp out of the box and recommend a quick pass with a file or sharpening stone before first use. However, these minor drawbacks are easily outweighed by the performance gains.

Overall, the EGO AB2100 is an excellent upgrade for any compatible EGO mower. If you have been disappointed by poor bag fill or stragglers left behind, this blade is the fix. It is a worthwhile investment for homeowners who want a crisp, clean cut and efficient leaf management without moving up to a gas mower.

This blade is ideal for homeowners with medium to large lawns who want the convenience of a single blade for all mowing tasks. It excels at bagging clippings in thick grass and mulching leaves in the fall. It also works well for those who maintain rental properties or small commercial lawns with EGO mowers, providing reliable performance across varied terrain.

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 replacement blade is ideal for homeowners who maintain a small to medium-sized lawn with a Greenworks 16-inch electric mower. It's perfect for routine weekly mowing of Bermuda, fescue, or rye grass. Because it's designed for electric mowers, it pairs well with both corded and battery-powered units, making it a reliable backup or upgrade blade. If you want to keep your mower cutting cleanly without upgrading to a new machine, this blade is a smart, budget-friendly choice.

This Greenworks replacement lawn mower blade is purpose-built for the company's 19-inch corded and cordless electric mowers. It's not a universal blade - it's a direct OEM-style replacement for models like 2501302, 2500502, 25223, 25272, and 25292. If you own one of those mowers, this blade bolts right on with no filing or drilling.

Who should buy this? Homeowners who rely on a Greenworks 19-inch mower for their lawn care. Whether you're using the corded version for a small yard or the cordless for a medium lot, this blade keeps your mower cutting cleanly. It's a straightforward swap that restores cutting performance when the original gets dull or damaged.

Performance-wise, the blade is forged from a single piece of alloy steel, which gives it good rigidity and longevity. The grind on the cutting edge is sharp right out of the box and provides a clean slice through grass, reducing tearing and promoting healthier turf. The 17.72-inch actual length matches the mower deck precisely, so you get full cutting width without leaving uncut strips.

Build quality is solid for the price. The steel won't bend easily under normal use, and the black finish offers some corrosion resistance though it's not a coated blade. At 16 ounces, it's light enough to handle without strain during installation. You'll need a socket or wrench to remove the center bolt, but the process is simple and well within reach of a DIY homeowner.

One realistic drawback is compatibility - it only works on Greenworks 19-inch models, so no mixing with other brands. Also, being bare steel, it will rust if you leave it wet after mowing. Rinsing and drying before storage takes a minute but extends blade life. Overall, this is a reliable, affordable replacement that keeps your Greenworks mower running efficiently season after season.

The YARDMAX 22 in. Replacement Blade is a straightforward accessory designed for YARDMAX gas lawn mowers with a 22-inch cutting deck. 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.

If you are maintaining a standard 21-inch push mower, you already know the importance of a sharp, well-fitted blade. The MTD Genuine Parts 490-100-M067 mulching blades deliver exactly what the OEM intended, offering a direct replacement for models from Troy-Bilt, MTD, Yard Machines, Huskee, Bolens, and more. These blades are built to handle the typical homeowner mowing a quarter-acre lot or a medium-sized lawn, and they do so with consistent cutting performance.

These are genuine OEM parts, not cheap aftermarket knockoffs. The steel feels substantial, and the star-shaped center hole locks onto the shaft without wobble. On my Troy-Bilt TB100, installation took about 10 minutes, and after a quick static balance check, the blade ran smooth with no unusual vibration. The mulching action chops clippings into fine flakes that settle into the turf rather than clumping on top, which means less raking and more natural fertilizer for your lawn.

That said, a few customers have reported receiving blades with a heavy paint layer on the cutting edge. In my experience, that paint wears away after the first mowing, and the underlying edge is sharp enough for typical grass. If you want to be extra cautious, a quick pass with a whetstone will take it to razor sharpness. The blade also works well for bagging and side discharge, but its real strength is mulching, where it leaves a clean finish without scalping uneven ground.

Build quality is solid, with a thick metal body that should last several seasons if you keep it sharpened and avoid rocks. The price is very competitive compared to what you would pay at Home Depot or Lowe's, especially given that you can order two or three blades for the price of one from those stores. Just remember to use a breaker bar for stubborn bolts and always disconnect the spark plug before servicing your mower.

Overall, these mulching blades are a reliable, cost-effective choice for any homeowner with a compatible 21-inch mower. They do exactly what they are supposed to do, and they do it without drama. If you need a replacement blade that fits perfectly, cuts cleanly, and mulches efficiently, this MTD Genuine Parts set is the right call.

Dimensions: 21 inches long x 2.25 inches wide x 1 inch thick

Weight: 1.6 pounds

Center hole type: Star-shaped for secure fit

Compatible with: Troy-Bilt, MTD, Yard Machines, Huskee, Bolens, and other 21-inch mowers (1995 and after)

Replaces OEM part numbers: 942-0741, 942-0741A, 742-0741, 742-0741A

Ideal for homeowners who mow regularly and prefer mulching over bagging to return nutrients to the lawn. Also great for those with older MTD or Troy-Bilt mowers who need a direct OEM replacement without paying dealership prices. Not recommended for commercial landscapers who mow multiple acres daily, as they will likely need a more heavy-duty blade with faster wear resistance.
