Shredded yellowing lawn tips often signal that your current cutting edge is worn or the wrong profile for your deck. When grass clumps beneath the deck, it is usually a sign that airflow suction is weak. Selecting the correct Mower Blade Lawn is critical for restoring that crisp, healthy look. You need a blade that matches your center hole geometry and cutting width exactly. A mismatch can cause severe deck vibration and strip spindle mount splines. We analyzed specifications for several top options to help you avoid these common pitfalls. The right choice depends on whether you prioritize bagging efficiency or mulching performance. Consider the steel gauge and lift wing profile before you buy. This ensures balanced operation and reduced vibration during your next mow. Many homeowners prefer a high-lift blade for better discharge velocity.
Before purchasing, verify the OEM part number and center hole shape. A 5-point star hole will not fit a 6-point star spindle, leading to dangerous installation errors. The process of sharpening your old blade can extend its life, but replacement is often safer. Look for hardened steel that resists corrosion and maintains edge sharpness. This is especially important if you mow in sandy soil or thick turf. The powder-coated finish on many new blades protects your hands during handling. It also prevents rust until the first cut reveals the steel. Choose a blade that aligns with your mower’s power limits. Battery-electric mowers often require thinner kerf blades to prevent engine bogging. This ensures your machine runs at optimal RPMs without straining the motor. Proper fitment is the single most important factor in your decision.
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
- Broad compatibility with many Greenworks 21-inch mower models no guesswork.
- OEM part means reliable fit, balance, and cutting performance.
- Easy to install and replace yourself without a dealer visit.
- Holds an edge well for a residential mowing schedule.
Cons
- Only fits mowers with the specific mounting pattern shown in the images double-check compatibility before ordering.
- Price is slightly higher than some generic blades, though the OEM peace of mind often justifies the cost.
- Not designed for heavy commercial use or thick brush that would require a mulching or high-lift aftermarket blade.
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.

Pros
- Excellent fitment for a wide range of mower models, as confirmed by many positive reviews.
- High lift design significantly improves grass collection and leaf bagging performance.
- Good value for the price, offering OEM-like quality at a lower cost.
- Easy to install with clear compatibility information provided.
Cons
- Some users may find the paint on edges wears off quickly during use, though this is normal and doesn't affect performance.
- Not suitable for mulching, as these are high lift blades optimized for bagging and discharge.
- The 6-point star hole may not fit older models with a different center hole shape, so double-check compatibility before ordering.
The Grasscool 942-04308 high lift mower blades are a direct replacement for a wide range of 42-inch deck riding mowers from Troy-Bilt, Cub Cadet, Craftsman, and other MTD brands. These blades feature a 6-point star center hole and are designed for bagging and side discharge applications. With a length of 21-3/16 inches and a high lift profile, they generate strong airflow to propel clippings into the collection bag or out the discharge chute.
These blades are best suited for homeowners and DIYers who own compatible mowers and want reliable cutting performance without paying OEM prices. The high lift design excels at handling tall, wet grass and leaves, making them a great choice for fall cleanup and routine mowing. Many users report perfect fit and improved bagging compared to worn-out original blades.
Build quality is solid for the price point. The blades are made from durable steel and come with a rust-resistant paint coating on the cutting edges. The paint also helps protect your hands during installation. The blades can be sharpened easily to extend their lifespan. Installation is straightforward if you follow the included compatibility notes, but be sure to check your current blade's center hole shape before ordering.
One limitation is that these are not designed for mulching. They are strictly for bagging and side discharge. Also, the 6-point star hole is specific to certain models; if your mower uses a 5-point star or S-shaped hole, you will need a different blade. Despite these constraints, the Grasscool blades offer excellent value for their intended use.
Overall, if you need a reliable set of high lift blades for a 42-inch deck mower from Troy-Bilt, Cub Cadet, or Craftsman, the Grasscool 942-04308 is a smart purchase. They deliver strong performance, easy installation, and a price that leaves room in your budget for other workshop needs.

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.

- 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
- Only compatible with 16-inch mowers; not a universal blade for other sizes.
- 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.

Pros
- Direct OEM replacement fit for popular 30-inch Toro TimeMaster and TurfMaster models
- Manufactured from high-strength steel capable of being resharpened for extended service life
- Factory pre-sharpened cutting edge protected by safety paint to preserve edge geometry before use
- Accurately matches factory spindle mounting geometry with 5/8-inch center and 5/16-inch side holes
Cons
- Mounting hardware, bolts, and washers are not included and must be reused from the mower
- Specific steel alloy grade and exact metal thickness are not specified in listing data
- Designed exclusively for specific dual-blade 30-inch decks and will not fit standard 21-inch or 22-inch walk-behind mowers
The UDC Parts 116-6358-03 Mower Blade is a direct replacement cutting component engineered specifically for 30-inch deck walk-behind mowers. This aftermarket blade replaces multiple original equipment manufacturer part numbers, including Toro 116-6358-03, 120-9500-03, 120-9500, 120-9500-S, 116-6358, 116-6358-S, and 20120P. Because 30-inch deck systems rely on two synchronized blades working together, keeping sharp, properly balanced blades installed is critical for maintaining an even cut across the entire mowing swath.
This replacement blade is best suited for residential homeowners operating Toro TimeMaster 30-inch models, such as the 20199, 20200, 21199, 21200, and 21810 series, as well as landscape maintenance operators utilizing commercial Toro TurfMaster or Exmark 30-inch units. Equipment owners seeking a direct, cost-effective replacement for worn, chipped, or bent factory blades will appreciate the broad cross-reference coverage across both consumer and commercial equipment lines.
Physical measurements for the blade include a 15-3/8-inch diagonal tip-to-tip length and an overall blade width of 2-3/4 inches. The mounting hub features a standard 5/8-inch round center hole flanked by two 5/16-inch side positioning holes spaced 1-1/4 inches from center to center. Aerodynamic lift is provided by a 25/32-inch air lift wing profile, paired with a 3-15/16-inch cutting edge length designed to lift turf blades efficiently for clean cutting, bagging, and mulching.
In terms of construction, the blade is made from high-strength steel designed to resist premature deformation and keep its cutting edge stable through standard turf maintenance. The blades arrive pre-sharpened from the factory and are coated with a green protective safety finish. As noted by the manufacturer, this surface paint wears away naturally along the cutting edge during initial mowing, and the steel edge can be resharpened with standard blade-maintenance tools as it dulls over time.
Installation is designed to be a direct swap with existing mower hardware, fitting directly onto the spindle assembly without requiring deck modifications. Mounting fasteners such as blade bolts, washers, and spindle adapters are not included in the package, meaning owners will need to inspect and reuse their original factory hardware. Equipment operators should ensure the mower engine is fully disabled and consult their mower service manual for proper blade orientation and recommended spindle bolt torque values.
Overall, the UDC Parts 116-6358-03 presents a practical, budget-conscious replacement option for restoring the cutting performance of 30-inch dual-blade mowers. Homeowners and property managers should confirm their mower model number, deck size, and mounting hole dimensions against the manufacturer fitment list prior to purchasing.
This replacement blade directly replaces OEM part numbers Toro 116-6358-03, 120-9500-03, 120-9500, 120-9500-S, 116-6358, 116-6358-S, and 20120P across compatible 30-inch cutting decks.

Commercial machine fitment includes Toro TurfMaster 30-inch models 22215, 22200, 22205TE, 22207, 22235, 22225, 22210, 22232, and 22232 T, as well as Exmark 30-inch mowers ECS180CKA30000, ECX200CKC30000, ECX180CKA30000, and ECKA30.
Diagonal blade length measures 15-3/8 inches from tip to tip with an overall width of 2-3/4 inches, tailored specifically for dual-blade 30-inch mower decks.
Mounting geometry consists of a 5/8-inch circular center hole and two 5/16-inch side alignment holes set at a 1-1/4-inch center-to-center outside hole spacing.
The blade profile incorporates a 25/32-inch air lift wing to generate deck airflow along with an active cutting edge length of 3-15/16 inches.
Common Mower Blade Questions
How do I identify my center hole shape?
Check the existing blade for a 5-point star, 6-point star, or bow-tie pattern. This determines spindle compatibility. A mismatch causes vibration and damage. Always measure the outer hole spacing if the shape is ambiguous to ensure a secure fit.
What is the difference between high-lift and mulching blades?
High-lift blades create strong suction for bagging or side discharge. Mulching blades have serrated edges that recut clippings. This keeps grass clippings distributed evenly. Choose based on your preferred grass clipping management method for the season.
Can I use a generic blade on my mower?
Only if the length, width, and center hole match exactly. Generic blades may lack the correct sail angle for your deck. This can reduce airflow and cutting quality. Stick to OEM-interchangeable parts for guaranteed performance and safety with your specific model.
How often should I replace my mower blade?
Replace blades every season if they show deep nicks or rust. Resharpening works for minor dullness. Severe damage compromises balance and safety. A stuck bolt often indicates it is time for a new blade assembly.
Why does my mower vibrate after installing a new blade?
Imbalance is the primary cause of deck vibration. Ensure the blade is centered on the spindle. Use a blade balancer to check for weight distribution. Uneven weight strains bearings and can lead to spindle failure over time.
