Replacement Lawn Mower Blades of 2026

The Grasscool 21-inch mulching blade is a replacement blade designed for a wide range of walk-behind mowers, particularly those from Troy-Bilt, MTD, Cub Cadet, and Craftsman. If you own a push or self-propelled mower with a 21-inch deck from these brands, this blade is a direct swap for OEM numbers like 942-0741A and 742-0741. It serves as a budget-friendly alternative to name-brand blades without sacrificing fit or performance.

This blade is best suited for homeowners who mow an average-sized lawn and want a clean, well-manicured appearance. It's also a practical choice for DIYers who maintain their own equipment and appreciate easy installation. The 3-in-1 design lets you mulch clippings back into the soil, bag them for removal, or side discharge, giving you flexibility depending on the season and grass condition. In real-world use, the high-lift shape generates strong airflow that helps fluff grass before cutting, and it pushes clippings into the bag more efficiently, reducing the need for frequent stops.

Build quality is solid for the price point. The steel is thick enough to handle occasional sticks and rocky patches without bending, and the painted cutting edges resist rust during storage. Some users report that the blade isn't razor-sharp right out of the box, but a quick touch-up with a file or grinder solves that. Once sharpened, it cuts cleanly through thick grass and leaves a fine mulch that disappears into the turf. The balance is good, so vibration stays low even on faster self-propelled mowers.

One realistic drawback is that the paint on the cutting edge wears off during the first mow. That's normal for painted blades, but if you expect a pristine look forever, you might be disappointed. Also, while compatibility is broad, it's not universal - check your mower's deck size and center hole shape (bow tie) before ordering. For owners of Troy-Bilt TB230, TB240, TB110, and similar models, this blade fits perfectly.

Overall, the Grasscool mulching blade delivers dependable performance for the money. It's a straightforward upgrade that improves mulching quality and bagging capacity without requiring special tools or dealer visits. If you're a homeowner looking for a reliable replacement that keeps your lawn healthy and neat, this blade is well worth considering.

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.

This blade fits many 21-inch cut mowers from MTD, Cub Cadet, Troy-Bilt, and Craftsman. Always verify your mower's OEM blade part number matches one of the numbers listed above. Common compatible models include:

Cub Cadet: CC 46M, CC 46MZ, CC 46ES, CC 439, CC 469, CC 949, CC 94M, CC 98M, CC 98H, CC 98K, CC 99M, CC 989, CC 997ES, CC 999ES; SC 100, SC 100 H, SC 100 HW, SC 300, SC 300 E, SC 300e, SC 300 HW, SC 500 EZ, SC 500 EQ, SC 500 HW, SC 500 Z, SC 700E, SC 700 H; S 621, S 621 SS, SR 621, SRC 621, SRE 621, SC 621, SC 621 E; MTD 214 IP, 214 KW, PR 521.

The Grasscool 21-inch mulching blade is designed specifically for Troy-Bilt and compatible walk-behind mowers with a bow tie spindle. If you own a Troy-Bilt TB110, TB230, or any of the dozens of models listed, this blade offers a straightforward replacement that doesn't require modding or adapters. It's built for the homeowner or DIYer who wants a reliable blade for regular lawn care without overspending on OEM parts.

In real-world use, this blade excels at mulching. The curved design and sharp cutting edges shred grass clippings into fine particles that settle back into the soil as nutrients. The high-lift wings also create strong airflow that fluffs the clippings for even distribution or powers bagging. During heavy growth, the reduced clogging is noticeable - the blade keeps spinning without wrapping wet grass around the center. Side discharging works fine too, though the mulching performance is the standout feature.

Build quality is respectable for a budget-friendly blade. The steel is thick enough to handle occasional rocks or roots without bending, and the paint coating on the cutting edges prevents surface rust during storage. Just be aware that the paint wears off quickly after a few passes on grass - that's normal. The bow tie hole fits snugly, and the blade comes pre-balanced, so you can install it without extra fuss. If you mow a standard quarter-acre lot with a Troy-Bilt mower, this blade will hold up for a full season or two before needing a sharpen.

There are limitations. The most important is the bow tie requirement - if your spindle has a star or 5-point pattern, this blade won't work. Also, the blade is designed for 21-inch decks, so it won't fit smaller or larger mowers. For homeowners who want a single blade that does it all without swapping, this is a great choice. Contractors with commercial mowers might prefer heavier-duty options, but for residential use it's more than adequate.

Bottom line: if you have a compatible Troy-Bilt mower with a bow tie spindle and want a dependable mulching blade that also bags and discharges well, the Grasscool blade is a solid buy. It delivers real performance gains over dull or generic blades and comes at a price that won't break your tool budget.

Always verify your spindle shape - this blade only fits bow tie center holes.

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.

Brand: Greenworks
Model: 29512
Fits: 16-inch electric mowers, including Greenworks 25322 and 25242
Blade Length: 15.75 inches (actual cutting width 16 inches)

Weight: 0.69 pounds
Dimensions: 15.75 x 1.97 x 0.71 inches

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.

If you own a Manscaped Lawn Mower trimmer, keeping the blade sharp is key to a comfortable grooming experience. The Wusuker 2 Pack Replacement Blade is designed specifically for the Lawn Mower 2.0, 3.0, and 4.0 models, offering a direct snap-in replacement that restores the trimmer's cutting performance. This set includes two blades, so you always have a fresh one ready when the current blade starts to dull.

These blades are best suited for anyone who uses a Manscaped Lawn Mower regularly, whether you're a grooming enthusiast or just want a hassle-free trim. The stainless steel and ceramic construction provides a good balance of sharpness and durability, resisting corrosion even in humid bathroom environments. In real-world use, the replacement process is straightforward: you simply pop off the old blade and snap the new one into place, no tools required. The fit is snug and secure, and the blade cuts cleanly without pulling or snagging.

Build quality is solid for the price point. The ceramic part of the blade stays cool during use, which adds to comfort, and the stainless steel edge holds its sharpness for several weeks of regular trimming. The manufacturer recommends replacing the blade every two to three months, which is reasonable for maintaining hygiene and performance. One potential limitation is that these blades only work with the specific Lawn Mower models listed, so if you have the 5.0 version, you'll need a different blade. Also, the need for periodic replacements means you'll have an ongoing consumable cost, but the two-pack helps stretch that out.

Overall, the Wusuker replacement blades are a practical and cost-effective solution for keeping your Manscaped trimmer in top shape. They deliver the sharpness and hygiene you need for confident grooming, and the easy installation makes them a no-brainer upgrade when your current blade starts to fade. If you want to maintain a smooth, irritation-free trim without buying a whole new trimmer, this two-pack is a smart buy.

If you're looking for replacement mower blades that punch above their weight, the UDC Parts 942-0741A 21-inch mulching blades are a solid choice. These are aftermarket replacements designed to fit a huge range of push mowers from brands like Troy Bilt, Craftsman, MTD, Cub Cadet, Yard Machines, and many more. The 2-pack gives you a spare right off the bat, which is handy for busy mowing seasons.

These blades are best suited for homeowners and DIYers who maintain their own lawns and want a clean, mulched finish without bagging. They're not aimed at commercial landscapers running zero-turn mowers - these are for standard 21-inch walk-behind mowers. But for that audience, the performance is excellent. Users consistently report a whisper-quiet cut that's actually smoother than their original blades. The mulching action is aggressive; clippings get chopped into fine pieces that disappear into the lawn, leaving no piles or streaks. Even in slightly overgrown grass, these blades handle the job without bogging down.

Build quality is a strong point. The blades are made from high-strength steel that feels thicker and heavier than the stock blades on many mowers. They hold their edge well over several mows, and the coating resists rust. Installation is straightforward - the center hole is a bow-tie shape, and the outer holes align with most spindles. Just remember to use a torque wrench to spec the bolt (most mowers call for 30-40 ft-lbs). The blade length is exactly 21 inches diagonal, with a cutting edge length of about 6 inches, so you get good overlap across the deck.

One realistic downside is the high-lift design. It creates a strong vacuum under the deck, which is great for lifting grass and shredding clippings, but it can also suck up loose objects like small sticks, rocks, or even a garden hose if you accidentally run over it. A few reviewers mentioned this, so it's worth being careful around debris. Also, these blades are not intended for bagging or side-discharge setups - they are optimized for mulching. If you need to switch to bagging, you might want a different blade.

Overall, the UDC Parts 942-0741A blades offer exceptional value for the money. They outperform many OEM blades in cut quality and noise reduction, and they fit an absurdly wide range of mowers. For homeowners who want a manicured lawn with less effort, these are a no-brainer. Keep a spare set handy, and you'll be set for a couple of seasons.

The Amorka 2-Pack Replacement Blade set is an aftermarket replacement trimmer cartridge engineered specifically for the Manscaped The Lawn Mower series of electric personal grooming devices. Despite the colloquial "Lawn Mower" branding, this accessory is designed exclusively for battery-powered personal body hair trimmers rather than outdoor turf or power-mowing equipment. The product is supplied as a two-piece bundle in black, designed to provide direct snap-in compatibility with Manscaped Lawn Mower 4.0, 3.0, and 2.0 trimmer handles.

This replacement cartridge set is best suited for owners of compatible Manscaped electric trimmers who require fresh cutting heads to maintain grooming performance, hygiene, and comfort. Buyers seeking replacement blades for personal grooming tools will find the multi-pack convenient for regular maintenance cycles. Because compatibility is strictly bounded by the mechanical snap-in interface of specific cordless trimmer bodies, prospective buyers must confirm that their trimmer handle matches the 2.0, 3.0, or 4.0 generation before purchase, as it will not fit third-party shavers or standard yard-care trimmers.

According to the product specifications, the Amorka replacement head incorporates a ceramic cutting blade paired with extra-small guide teeth. The manufacturer highlights that the ceramic cutting edge is pushed back approximately 3 millimeters from the perimeter edge to promote controlled trimming across sensitive areas. The package carries listed dimensions of 5.905 by 4.724 by 1.181 inches. The snap-fit mechanism replicates the factory attachment interface, allowing users to slide out an aged cutting head and seat the new cartridge securely without external tools or fasteners.

Ease of ownership is centered on routine replacement and hygiene management. The manufacturer recommends swapping the blade assembly every 2 to 3 months under regular usage to counteract gradual edge dulling and maintain peak cutting efficiency. Routine cleaning is supported by the removable cartridge architecture, which allows hair debris to be rinsed or brushed out quickly after detachment. Having two cartridges in a single package facilitates hygienic rotations, ensuring a clean replacement is available when the primary blade completes its recommended service cycle.

Based on the supplied technical specifications, the Amorka 2-Pack offers a targeted, practical replacement solution for users looking to refresh their Manscaped The Lawn Mower 2.0, 3.0, or 4.0 electric trimmers. While users must keep in mind the periodic replacement requirement and narrow platform compatibility, the ceramic edge configuration and snap-in simplicity provide reliable ownership value. For personal care maintenance, it serves as a budget-conscious, functional alternative to individual OEM replacement modules.

Compatibility for the Amorka replacement blade is explicitly documented for Manscaped The Lawn Mower 4.0, 3.0, and 2.0 electric personal trimmers. The cartridge utilizes a proprietary snap-in latching interface tailored to these specific cordless handles.

Buyers should note that this blade set is not compatible with other electric razor brands, beard trimmers, or standard lawn and garden power equipment. Verifying the exact trimmer model on the handle housing is recommended before purchasing.

The manufacturer recommends replacing the trimmer blade cartridge every 2 to 3 months depending on frequency of use to prevent edge degradation and hair pulling. Regular replacement supports hygienic grooming standards across sensitive skin areas.

For routine upkeep, the blade unit can be snapped off the trimmer body for debris removal and gentle cleaning. The unused spare cartridge should be kept in a dry environment inside its packaging to preserve the cutting edges until needed.

The MANSCAPED Lawn Mower 5.0 Ultra Replacement Trimmer Blade is a dedicated accessory for the brand's popular groin hair trimmer. While it might not be a traditional power tool, it shares many of the same engineering principles: precision, durability, and user safety. This ceramic blade head with a built-in metal guard is designed to replace the original blade every three months, ensuring your trimmer continues to deliver a smooth, nick-free experience.

This blade is best suited for anyone who already owns a Lawn Mower 5.0 Ultra and wants to maintain its performance. That includes DIYers, contractors, and homeowners who appreciate a well-maintained grooming tool for personal care on the jobsite or at home. The snap-in design makes replacement effortless, so you can get back to your routine without fuss.

In real-world use, the ceramic blade stays sharp and runs cool thanks to its heat-resistant properties. The metal guard acts like a comb, lifting hair away from the skin before cutting, which significantly reduces the risk of nicks. The blade is also waterproof, so you can rinse it clean without worry. The pre-lubrication helps it glide smoothly, maintaining consistent cutting speed even when tackling thicker hair.

Build quality is solid for a trimmer blade. Ceramic is naturally harder than steel and resists rust, but it can be more brittle if dropped. The metal guard is a nice touch for added safety. However, the blade is only compatible with the Lawn Mower 5.0 Ultra, so it won't fit older models or other brands. The need to replace it every three months is a recurring expense, but it keeps the trimmer performing like new.

Overall, the MANSCAPED Lawn Mower 5.0 Ultra Replacement Trimmer Blade is a worthwhile investment if you want to extend the life of your trimmer and maintain a comfortable grooming experience. It's a simple, effective way to keep your tool in top shape without buying a whole new unit. For anyone serious about personal grooming on the go, this replacement blade is a practical choice.

The MANSCAPED The Lawn Mower SkinSafe Replacement Trimmer Blade is a ceramic blade cartridge designed specifically for the 2.0, 3.0, and 4.0 models of the company's popular below-the-waist trimmer. It's a direct OEM replacement part, not a generic third-party option, so you get the same fit and performance as the original blade that came with your device.

This replacement blade is best suited for anyone who already owns a MANSCAPED Lawn Mower trimmer and wants to maintain its factory-level cutting ability without buying a whole new unit. It's especially practical for DIY grooming enthusiasts and guys who prefer a dedicated tool for sensitive areas. The ceramic construction is a big plus: it resists rust, stays sharp, and doesn't heat up as much as metal blades, which helps reduce skin irritation during use. The snap-in design makes swapping blades a five-second operation, and each cartridge comes pre-lubricated so you get smooth cuts right out of the box.

In real-world use, this blade delivers clean, precise trims on body hair without tugging or pulling. The built-in guard helps protect against nicks, and the waterproof rating means you can rinse the blade under the faucet after each session to keep it clean and sanitary. Build quality is typical MANSCAPED: solid plastic housing with a precisely aligned ceramic cutting element. It's lightweight and doesn't add any bulk to the trimmer handle.

One realistic drawback is that if your Lawn Mower 2.0 is several years old with a tired motor, a new blade head won't fix the underlying loss of RPM. Some users with older units have reported that the trimmer still doesn't cut as well as it used to after the swap. Also, the blade is only sold in single packs, so you'll need to buy multiples if you want to have spares on hand for the recommended three-month replacement cycle.

Overall, this is a solid OEM replacement blade that does exactly what it's supposed to do. If you have a relatively new or well-maintained Lawn Mower 2.0, 3.0, or 4.0, swapping to this ceramic cartridge will restore like-new performance. It's an easy, affordable way to keep your grooming tool in top shape without upgrading to an entirely new trimmer.

Product Type: Replacement Trimmer Blade (Cartridge)
Blade Material: Ceramic
Compatibility: MANSCAPED Lawn Mower 2.0, 3.0, 4.0
Water Resistance: IPX7 (Waterproof)
Dimensions: 3 x 1 x 3 inches
Weight: 0.32 ounces (9 grams)

UPC: 810040574023

This replacement blade is ideal for regular grooming of below-the-waist hair, including the groin area. It's best used as a quarterly maintenance part to keep your MANSCAPED Lawn Mower trimming at peak performance. The ceramic construction makes it suitable for use in the shower, and the skin-safe design gives extra confidence when grooming sensitive skin. Not intended for head or facial hair.

Before purchasing this replacement blade, confirm which version of the Lawn Mower you own (2.0, 3.0, or 4.0). The cartridge snaps into the handle. If your trimmer is an older 2.0 that has seen heavy use for years and the motor feels weak, a new blade may not restore full cutting power. In that case, consider upgrading to a newer trimmer base unit instead. For 3.0 and 4.0 models, this blade works perfectly and restores original sharpness. Replacing the blade every three months is recommended by MANSCAPED to maintain hygiene and performance.

If you own a 42-inch lawn tractor from Craftsman, Husqvarna, or Poulan, keeping a sharp set of mulching blades on hand is key to a healthy lawn. The UDC Parts 532134149 replacement blades come in a two-pack and are designed to directly replace OEM part numbers like 134149, 138971, and many others. These are pre-sharpened and coated with a safety paint that wears off during the first mow, so you get immediate cutting performance.

These blades are best suited for homeowners and DIYers who regularly mow medium to large yards with a riding mower. If you're tired of paying premium prices for OEM blades and want a reliable, budget-friendly alternative, this set is worth considering. Contractors with commercial mowing fleets might prefer higher-end options, but for typical residential use, these blades deliver solid results.

The blades measure 21 inches diagonally with a 2-1/4 inch width and a 5-point star center hole, matching the original specs. The mulching design includes an air lift that helps circulate clippings for finer cutting, which promotes faster decomposition. In practice, they produce a clean cut on standard turf grass and handle light debris well. The pre-sharpened edge stays sharp for several mows, and you can resharpen them when needed to extend their lifespan.

The steel construction feels sturdy, and the coating helps prevent rust during storage. Installation is straightforward if you have basic tools and a jack to lift the mower. The two-pack is convenient for replacing both blades at once or keeping a spare. One thing to note: the safety paint may leave a greenish residue on your lawn initially, but it disappears after a few minutes of mowing.

The main limitation is compatibility. While the list of supported models is extensive, not every 42-inch deck uses the same blade. Always verify your mower's model number before ordering. Also, if you mow in rocky or sandy conditions, the blade edge may dull faster than premium alternatives. Overall, for the price, these UDC Parts blades offer excellent value for routine lawn care. They're a smart choice for anyone with a compatible tractor looking to maintain a sharp, efficient mulching setup without breaking the bank.
