Best Double Sided Lawn Mower Blades Review
MaxPower 46\” 2-Blade Set – Best Overall
The MaxPower 561739B lands with a punch for riders seeking double-sided lawn mower blades that balance reach, durability, and compatibility. Each blade measures 23 x 2-3/4 inches with a 5-point star center and replaces a long list of OEM numbers, reducing fitment guesswork for popular 46-inch Craftsman, Husqvarna, and Poulan decks. A powder-coated, pre-sharpened finish means the first pass reveals the true cutting edge, answering the common pain point of uneven, torn grass.
In real-world mowing, this two-blade set creates a broad, even swath on mid to large yards, handling weekly cuts and moderate overgrowth with confidence. The sharpening from the factory translates to a crisp cut that improves lawn health and bagging performance, while the USA-made steel holds an edge respectably through a season. The 5-point star hub makes installs straightforward, though users must match OEM numbers to avoid spindle mismatch. Wet, dense turf can reduce lift slightly, so double-cutting might be needed after heavy rain.
Against the Greenworks 20-inch replacement blade, the MaxPower’s 46-inch deck coverage and dual-blade setup offer superior throughput for larger properties. Compared with the Wadoy 21-inch high-carbon option, MaxPower trades ultra-tough metallurgy for broader compatibility across gas riders and lawn tractors. It’s ideal for homeowners with 46-inch Craftsman/Husqvarna/Poulan decks seeking reliable OEM replacement performance; feature-for-feature, it delivers more deck coverage per pass than the single-blade Greenworks option.
- Wide 46′ coverage
- OEM replacements
- 5-star center fit
- Pre-sharpened edge
- USA-made build
- Wet grass lift
- Must verify OEM
- Not for 21′ decks
Greenworks 20\” Steel Blade – Best Budget Friendly
Greenworks’ 20-inch replacement blade feels precise and purposeful, engineered to restore like-new cutting on models 25022 and 25112. Its actual length of 19.69 inches and single-piece steel build deliver a tight fit and stable balance, solving the common vibration and ragged-cut issues seen with worn or off-spec blades. If you want clean edges and efficient airflow on a corded Greenworks mower, this blade is a plug-in fix.
On the lawn, the blade produces a clean, even cut that improves mulching and bagging consistency on weekly maintenance schedules. The one-piece steel design resists flex and keeps its profile through minor sticks and occasional sandy patches. It’s perfect for small to medium suburban yards and shines on dry to slightly damp turf, though heavy, overgrown grass may require a slower pace or a second pass.
Compared to the MaxPower 46-inch set, this Greenworks blade prioritizes simplicity and exact-fit over deck coverage and cross-brand compatibility. Versus the Wadoy 21-inch blade, it’s lighter-duty but tailored for the corded 20-inch platform, making installs and performance more predictable. Ideal for Greenworks users who want hassle-free replacements with accurate sizing, it offers cleaner cuts but less durability than the high-carbon Wadoy option.
- Exact-fit sizing
- One-piece steel
- Clean cutting
- Low vibration
- Model-specific
- Less heavy-duty
- Overgrowth struggles
Wadoy 21\” Greenworks Blades – Best High-Durability
The Wadoy 21-inch blade set brings a rugged, high-durability edge to Greenworks 21-inch platforms like MO40L4413, MO40L03, and MO48L4422. Built from high-carbon steel with a rust-resistant coating, these blades are tuned for clean, even cuts and longevity under tough mowing conditions. If you’re battling abrasive soil or frequent mowing, the durable metallurgy answers the pain point of blades dulling too quickly.
In testing, the pair handles weekly trims and moderate overgrowth with solid lift and consistent clipping size, boosting mulching and bagging efficiency. Installation is straightforward, and the corrosion-resistant finish helps through damp storage or morning dew. On very wet or tall grass, airflow can taper, but slowing the pace maintains a tidy finish. Balance is good out of the box, minimizing vibration on 21-inch decks.
Stacked against the Greenworks 20-inch blade, Wadoy offers added durability and a larger deck fit, making it better for heavier use on compatible 21-inch models. Compared to the MaxPower 46-inch set, it trades acreage throughput for toughness and exact model compatibility. Best for battery or electric Greenworks owners who want longer service intervals and sharp results; in performance-to-durability terms, it outmuscles the standard Greenworks blade while remaining easier to fit than cross-brand options.
- High-carbon steel
- Corrosion-resistant
- Clean finish
- Easy install
- Low vibration
- Wet grass drag
- Model-limited
- Heavier blade
How to Choose the Right Double-Sided Lawn Mower Blades
Match and Fitment (Most Important)
- Confirm OEM compatibility: match the exact OEM part number in your manual to the blade listing.
- Measure precisely: length, width, center-hole type/size (e.g., 5-point star), and blade count per deck.
- Deck size and model: ensure the blade is designed for your mower brand/model and deck width (e.g., 20″, 21″, 46″).
Cutting Performance and Edge Profile
- Look for precision-sharpened edges for a clean, even cut and better lawn health.
- Double-sided or dual-edge sharpening can extend time between sharpenings and maintain consistent cut quality.
- Mulching vs. high-lift profiles: mulching for finer clippings and lawn nutrition; high-lift for strong bagging and clean discharge.
Material and Build Quality
- High-carbon or one-piece forged steel provides superior strength and longer life.
- Powder coating or anti-corrosion finishes protect during storage and early use.
- Thickness and weight balance reduce vibration and improve durability.
Durability and Maintenance
- Choose blades noted for wear resistance if mowing tough or sandy soil.
- Balanced blades reduce spindle strain and extend mower life.
- Easy installation features (standardized holes, clear markings) save time; always torque to spec and check balance after sharpening.
Safety and Use Considerations
- Replace blades when bent, cracked, or excessively worn—don’t attempt to straighten.
- Verify rotation direction and install with cutting edge oriented correctly.
- Use proper PPE; disconnect power/battery or spark plug before changing blades.
Quick Tips by Scenario
- Large 2-blade decks (e.g., 46″): prioritize OEM fit, matching center-hole pattern, and balanced pairs.
- Greenworks 20″/21″ corded/battery models: choose blades made specifically for your model length and mounting spec.
- Heavy-duty users: opt for high-carbon, coated blades with reinforced edges for longevity.

FAQs
What makes a double-sided lawn mower blade better?
Double-sided lawn mower blades offer extended use between sharpenings because you can flip the blade to utilize a fresh, sharp cutting edge. This efficient design saves time and money, ensuring a consistently clean cut for your lawn.
How important is OEM compatibility when choosing blades?
OEM compatibility is crucial. Using a blade not designed for your specific mower model can lead to improper fit, imbalance, potential mower damage, and even safety hazards. Always match the OEM part number or meticulously verify measurements.
What type of steel is best for lawn mower blades?
High-carbon steel or one-piece forged steel are the most durable options. These materials offer superior strength, wear resistance, and longevity, especially when mowing in challenging conditions. Investing in quality steel for your double-sided lawn mower blades pays off in the long run.
How often should I replace my lawn mower blades?
Replace blades when they become bent, cracked, or excessively worn, even if they still appear to hold an edge. Dull or damaged blades tear the grass instead of cutting it cleanly, leading to lawn health issues. Regular inspection and timely replacement are key for optimal performance.
The Bottom Line
Selecting the right double-sided lawn mower blades ultimately hinges on a precise match for your mower model and your specific lawn care needs. Prioritizing OEM compatibility, understanding edge profiles, and investing in durable materials like high-carbon steel will ensure a clean cut, extended blade life, and optimal mower performance.
Don’t underestimate the value of preventative maintenance – balanced blades and proper installation are key to avoiding costly repairs.
