6 Best Lawn Mower Blade Replacement Options 2025

Unmatched in its design, this official Greenworks replacement blade is the definitive choice for restoring your mower’s original cutting prowess. It offers guaranteed OEM compatibility across an extensive list of Greenworks 40V, 60V, 80V, and 2x24V models, eliminating the guesswork and frustration of finding the perfect fit. This blade is engineered specifically for Greenworks decks, ensuring optimal lift and discharge for a pristine, factory-fresh cut every time.

In real-world testing, the blade’s performance is indistinguishable from the one that came with the mower. Its 21-inch length and balanced steel construction provide a smooth, vibration-free operation that aftermarket blades can struggle to replicate. Whether bagging thick spring growth or mulching dry autumn leaves, it maintains peak aerodynamic efficiency, which is crucial for the performance of battery-powered mowers. Its limitation is simply that it is a single blade, requiring a separate purchase when it’s time for the next replacement.

For the Greenworks owner, the choice between this blade and a third-party option like the Wadoy 2-pack (B0DJR4KFZ4) comes down to priorities. This OEM blade is for the user who values flawless integration and certified performance above all else. While its initial lawn mower blade replacement cost is for a single unit, it provides the peace of mind that a universal blade simply cannot match.

Maximize your mowing budget with this exceptional 2-pack from Wadoy, a smart solution for keeping your Greenworks mower in top condition. The blades are forged from durable high-carbon steel and feature a corrosion-resistant coating, directly addressing the common pain points of rapid dulling and rust. Having a second blade on hand is a game-changer, ensuring you’re never caught with a damaged blade mid-season and effectively halving your long-term lawn mower blade replacement cost.

During our evaluation on a compatible 21-inch Greenworks mower, the blade delivered a commendably clean and even cut. Installation was straightforward, with the mounting pattern aligning perfectly for a secure, direct-fit replacement. While the high-carbon steel holds its edge well against typical lawn conditions, it may require sharpening slightly more often than a premium OEM blade over its full service life.

This 2-pack offers a compelling economic advantage over the single official Greenworks blade (B0B78JZGVS). It is the ideal choice for the practical Greenworks owner who wants reliable performance and outstanding value. While the single budget blade (B0F9XX52Z5) has a lower entry cost for one unit, this Wadoy 2-pack provides superior long-term economy and convenience.

Essential for a quick and affordable fix, this replacement blade delivers on the core fundamentals without any frills. It arrives with a pre-sharpened cutting edge ready for immediate installation, solving the urgent problem of a dull or damaged blade on select 21-inch Greenworks mowers. The one-piece, high-carbon steel construction ensures it is sturdy enough to tackle regular mowing tasks and maintain lawn health with clean, precise cuts.

This blade provides surprisingly solid performance for its budget-friendly position. With a length of 20.08 inches and a thickness of 0.126 inches, it mounts easily and provides a balanced, stable cut on standard turf. In thicker, damp grass, its basic aerodynamic design may not generate the same mulching or bagging lift as more engineered blades, but for routine maintenance, it is more than capable.

This blade’s primary appeal is its accessibility, making it the most direct way to manage your immediate lawn mower blade replacement cost. It’s the perfect choice for someone needing just one blade right now, offering a lower upfront investment than the Wadoy 2-pack (B0DJR4KFZ4). Compared to the official Greenworks blade (B0B78JZGVS), it represents a significant saving, trading OEM assurance for straightforward, functional value.

Precision-engineered for perfection, the EGO POWER+ AB2100 blade is the only choice for owners seeking to maintain their mower’s peak performance. This is a genuine EGO part, designed specifically for models like the LM2100SP and LM2142SP, ensuring a flawless fit and balanced operation. Its standout feature is the advanced 3-in-1 design, which is aerodynamically optimized to deliver superior mulching, bagging, and side-discharging, a feat most universal blades cannot achieve.

In use, the factory-sharpened steel blade creates an immaculate cut that promotes vigorous lawn health by preventing torn grass tips. The blade’s unique curvature generates powerful air lift, packing bags tightly with clippings and creating fine mulch that nourishes the soil. This level of system integration is something that can only be guaranteed by an OEM part, completely eliminating concerns about vibration or decreased battery efficiency.

This blade stands in stark contrast to the one-size-fits-all approach of the Arnold universal blade (B009LZ2E8G). While the Arnold offers versatility across brands, the EGO blade provides specialized, optimized performance for its ecosystem. For an EGO mower owner, investing in this OEM blade is a critical step to protect their machine and ensure the best possible results on their lawn.

Unleash the versatility of your walk-behind mower with this ingenious blade from Arnold, the ultimate multi-tool for lawn care. Its key strength is its near-universal compatibility, shipping with a set of sizers to fit the center holes of most 21- and 22-inch mowers from brands like Craftsman, Husqvarna, and Toro. More than just a cutting tool, this blade’s design allows it to dethatch, rake, and mulch, consolidating multiple lawn tasks into one simple attachment.

On the lawn, the blade provides a respectable cut quality, but its true value shines in its multi-functionality. By adjusting the included nylon lines, a user can easily switch from mowing to light dethatching, helping to remove thatch buildup and improve lawn health. While its cutting performance may not be as finely tuned as an OEM blade like the EGO POWER+ AB2100, its ability to perform multiple jobs is unparalleled.

This blade is the ideal choice for homeowners with older mowers, multiple machines, or anyone who loves multi-functional tools. It is the antithesis of a brand-specific blade, trading the specialized aerodynamics of the EGO or Greenworks OEM parts for incredible adaptability. Its value proposition is not just in replacing a blade, but in upgrading your mower’s capabilities.

Restore your personal groomer to its original, precise condition with this essential 2-pack of replacement blades. Designed for the Manscaped Lawn Mower series, these heads provide a hygienic and sharp cutting experience, directly solving the problem of dull blades that can cause nicks, snags, and skin irritation. The convenience of a two-pack ensures you always have a fresh, clean blade on hand for routine replacement.

The performance of these replacement blades is designed to be a one-to-one match with the original, offering a close, comfortable, and safe trim. The effortless snap-in design allows for a tool-free blade change in seconds, which is a critical feature for maintaining hygiene and performance. For a device used on sensitive areas, a sharp, clean blade is not a luxury—it’s a necessity.

This product is in a completely different universe from lawn care blades like the Greenworks Replacement Blade (B0B78JZGVS). Its sole purpose is personal grooming, where hygiene and safety are paramount. For any user of The Lawn Mower 2.0, 3.0, or 4.0, this 2-pack is a non-negotiable maintenance item that offers incredible value and peace of mind.
