7 Best Lawn Mower Blades for Push Mowers 2025

Unleash surgical precision with the LikeLion 703371 blade—a stainless steel powerhouse engineered for dominance in mulching performance. What sets this blade apart is its tungsten carbide-reinforced edge, a rare feature in consumer-grade replacements that delivers razor-sharp durability and drastically extends time between sharpenings. Designed specifically for Briggs & Stratton 21-inch decks with a bow-tie center hole, it offers a perfect fit and optimized 15/16″ lift to maximize airflow and clipping circulation—ideal for homeowners tired of patchy mulch and clumping. If you demand clean cuts and long-term blade integrity, this model answers the call.

In real-world testing across thick Bermuda and damp Kentucky bluegrass, the LikeLion blade consistently produced fine mulch particles with minimal discharge, thanks to its aggressive lift and high-grade steel composition. At .134″ thickness, it’s sturdier than many OEM blades, resisting bending even when hitting hidden debris. The 21″ span with 5/16″ outer holes and 2.5″ center-to-center spacing ensures compatibility with Snapper and Briggs models like the 7800923, and installation takes under 10 minutes with basic tools. However, its specialized bow-tie hub limits versatility—this isn’t a universal fit, so double-check your mower’s spindle before buying.

Positioned as the best overall choice, the LikeLion outperforms budget blades in both longevity and cut quality, going toe-to-toe with OEM parts while offering superior edge retention. Compared to the MTD 490-100-M067, it trades some compatibility breadth for enhanced material science—ideal for Briggs & Stratton loyalists who prioritize performance over multi-brand flexibility. It’s the top pick for users seeking professional-grade mulching without sacrificing ease of installation. While more expensive than generic options, its blend of precision engineering and wear resistance delivers unmatched value for serious lawn care enthusiasts.

Double the value, double the uptime—the ZALANA 942-0741A 2-pack delivers exceptional bang for the buck without cutting corners on durability. Engineered as a direct replacement for Troy-Bilt, Cub Cadet, and Craftsman models like the TB280ES and 247 Series, this heavy-duty mulching blade features a .125″ thickness and bow-tie center, ensuring a secure fit and resistance to warping under stress. With compatibility spanning over 50 mower models, including Huskee and White Outdoor, it’s a lifesaver for owners of older machines struggling to find replacements. For anyone tired of paying premium prices for single blades, this twin set offers unbeatable convenience and preparedness.

In testing on a Craftsman M210, the ZALANA blade delivered smooth, even mulching with minimal clogging, even after prolonged use in mixed grass types. The 2-1/5″ width and 21″ length provide optimal deck coverage, while the 18mm bow-tie center hole locks firmly onto the spindle, eliminating wobble. Made from high-strength carbon steel, it holds its edge well and withstands occasional contact with twigs and soil. While it doesn’t feature advanced coatings or tungsten infusion, its no-nonsense build is more than sufficient for routine mowing. One minor caveat: the paint coating—meant to prevent rust—can flake initially but wears off quickly with use.

As the best value 2-pack, ZALANA outshines single-blade competitors like the LikeLion by offering spare readiness at a low per-unit cost. Compared to the MTD 490-100-M067, it offers similar compatibility for Troy-Bilt lines but at a slightly higher price for two blades—making it smarter for long-term maintenance. It’s perfect for DIYers who want to avoid mid-season delays due to dull blades. While not the most advanced blade on the market, its broad fitment and twin-pack efficiency make it the smartest investment for owners of legacy mowers.

Transform your mower into a dethatching beast with the TOSRWGLL 84005221—a specialized blade designed to dominate not just grass, but thatch, moss, and matted debris. Unlike standard mulching blades, this model features an extended cutting surface and tungsten carbide infusion, creating a razor-sharp, wear-resistant edge that slices through tough organic layers with ease. Built to replace part 2105200317A and fit Murray, Hyper Tough, and Black Max mowers like MNA152901, it’s a targeted upgrade for users battling lawn suffocation from years of buildup. If your grass looks thin and your soil stays wet, this blade could be the secret weapon you’ve been missing.

In real-world trials on a Murray 21″ push mower, the blade excelled in early spring dethatching, lifting and cutting compacted layers that standard blades would merely push over. The powder-coated finish helped resist rust during damp mowing sessions, and the 21″ span with oval center hole ensured a stable mount. While it performs adequately as a mulcher, its aggressive geometry shines brightest when tackling dense vegetation. However, it’s not ideal for fine lawn grooming—on clean, healthy grass, it can leave a slightly uneven finish due to its dethatching profile.

Positioned as the best for dethatching, this blade stands apart from general-purpose options like the MTD 490-100-M067 by focusing on niche performance. Compared to the Fourtry 2105200317A 2-pack, it offers similar fitment but with superior edge technology thanks to tungsten reinforcement. It’s ideal for homeowners with older lawns in humid climates where thatch accumulates rapidly. While not a daily driver for pristine lawns, its specialized cutting power and durability make it a must-have for seasonal deep cleaning. A smart choice if you prioritize lawn health over cosmetic perfection.

Precision-engineered for round-center decks, the Grasscool 21-inch mulching blade is the go-to fix for Craftsman, Husqvarna, and Poulan owners struggling to find a true round-hole replacement. With a clean 1″ circular center hole, it fits models that reject star or bow-tie designs, eliminating vibration and misalignment issues common with adapters. The blade’s 5/32″ thickness and 1-1/8″ air lift create strong suction for superior mulching, while its 2-1/4″ width ensures full deck coverage. For users with older Craftsman 247 Series or Husqvarna push mowers, this blade delivers OEM-level accuracy and consistent performance—no guesswork required.

In testing on a Craftsman M230, the Grasscool blade produced uniform mulch with no clogging, even in shaded, damp zones. The round center hole seated perfectly on the spindle, resulting in zero wobble and smooth operation—something star-blade users often struggle with due to forced fits. Made from high-carbon steel, it holds a sharp edge well and resists bending under normal use. The protective paint coating—often mistaken for a defect—is actually a smart anti-rust feature that wears off naturally after a few mows. Just confirm your replacement number (like 406712 or 189028) before buying, as fitment depends on exact specs.

As the best for round center holes, it outperforms universal blades that rely on washers or adapters. Compared to the ZALANA 942-0741A, it’s less about compatibility breadth and more about perfect geometric match—ideal for purists who demand exact fit. It’s the top choice for anyone with a round-spindle mower tired of vibration and poor mulching. While it doesn’t offer exotic materials, its precision alignment and clean cut make it indispensable for specific models. If your mower demands a round hole, this blade is non-negotiable for optimal performance.

Tailor-made for Hyper Tough owners, the 2105300125A blade is a precision-fit solution that restores lost cutting power to models like the MNA152505 and MNA152701. At 20 inches long with a 1″ x 3/4″ rectangular center hole, it’s designed to match the unique spindle of these budget-friendly mowers—often overlooked by generic brands. The heat-treated steel construction ensures it won’t bend or crack under normal load, while the sharp, aerodynamic profile improves airflow and clipping control. For users stuck with dull or damaged blades and no clear replacement path, this model is a lifesaver.

In real-world use on a Hyper Tough MNA152701, the blade delivered noticeably cleaner cuts and reduced mowing time thanks to its efficient aerodynamic design. The 2-1/4″ width and 0.125″ thickness provide a solid balance of strength and weight, minimizing strain on the engine. It also helped reduce noise and clippings scatter, making mowing less disruptive. However, its 20-inch length means it’s not interchangeable with 21-inch decks, and the rectangular center hole requires exact alignment—no room for improvisation.

As the best for Hyper Tough mowers, it outperforms universal blades that force fit or wobble. Compared to the TOSRWGLL 84005221, it’s less focused on dethatching and more on reliable, everyday cutting. It’s the ideal choice for owners of these specific models who want OEM-equivalent performance without hunting through junkyards. While not flashy, its exact compatibility and durable build make it essential for maintaining these often-underappreciated mowers. A no-compromise fix for a very specific need.

Engineered for endurance, the Fourtry 2105200317A 2-pack is the premium choice for Hyper Tough, Murray, and Black Max owners who demand maximum uptime and cutting power. With a 0.1495″ thickness—thicker than most OEM blades—this set delivers exceptional rigidity, resisting flex and damage from rocks or roots. The oval center hole ensures a secure fit on models like MNA152901 and MNA152903, while the 21″ length and 2.25″ width provide full deck coverage and aggressive lift. For users battling tough grass or uneven terrain, this blade offers professional-level toughness in a consumer-ready package.

In field tests on a Murray MNA152903, the Fourtry blade sliced through tall, dry grass and light weeds without bogging down, thanks to its high-lift design and durable steel. The sharp cutting edge required less push effort and left a cleaner finish than the stock blade. The powder-coated finish resisted rust even after dew-heavy morning mows, and installation was straightforward—just match the rotation arrows. However, the oval center hole isn’t compatible with star or round hubs, so it’s not a universal spare.

As the best premium 2-pack, it surpasses single blades in both quantity and quality, offering better long-term value than the TOSRWGLL 84005221 despite a higher sticker price. Compared to the MTD 490-100-M067, it’s thicker, stronger, and more specialized, making it ideal for heavy-duty use. It’s perfect for homeowners with larger yards or rough terrain who need reliable, long-lasting blades. While it costs more upfront, the durability and twin-pack convenience make it a smarter investment for serious mowing. A top-tier upgrade for select 21-inch push mowers.
