6 Best Lawn Mower Blades for Exmark (2025 Guide)

Built tough for commercial demands, the MaxPower 561139B blade set delivers industrial-grade durability and consistent cutting performance across 60-inch Exmark decks. These 20-1/2-inch triple blades feature a 15/16-inch center hole and precision sharpening straight from the factory, making them a plug-and-play upgrade that eliminates the need for initial tuning. With a heavy-duty 2.5-inch width and powder-coated finish that burns off during first use, they’re engineered to resist corrosion while maintaining edge integrity under high-RPM stress—perfect for landscapers battling thick, wet grass or frequent mowing cycles.

In real-world testing on Exmark Laser Z and Turf Ranger models, these blades held up impressively over multiple seasons, showing minimal wear even after hundreds of acres. The balanced design reduces vibration, protecting spindle bearings and improving deck stability at full throttle. They excel in side-discharge and bagging setups, where their moderate lift profile ensures efficient grass ejection without overloading the engine. However, they aren’t optimized for deep mulching, as the airflow isn’t aggressive enough to re-cut clippings finely in dense conditions.

Compared to the Oregon G3 mulching blades, the MaxPower set trades some aerodynamic finesse for raw toughness and cost efficiency—making it ideal for contractors prioritizing longevity and value over specialized cutting modes. It’s the go-to replacement for fleet managers needing reliable, OEM-matching performance without premium pricing. While it doesn’t offer the high-lift suction of pricier Oregons, it outperforms in durability per dollar, especially when maintaining large turf areas with mixed mowing patterns.

Engineered for elite mulching performance, the Oregon 6PK G3 Gator blades redefine how Exmark mowers handle grass clippings, transforming them into fine, lawn-nourishing mulch with surgical precision. These 20-1/2-inch blades feature a 3.0-inch airfoil design and 1-inch lift, generating a powerful vortex that keeps clippings circulating under the deck for multiple cuts before discharge. The 0.203-inch thickness ensures rigidity at high speeds, while the 15/16-inch center hole guarantees a secure fit on 60-inch Exmark mowers like the Lazer Z and Quest series.

During intensive mulching trials on damp, overgrown lawns, the G3 blades consistently delivered even dispersion and near-invisible clippings, outperforming standard high-lift and OEM blades. The advanced gullet design enhances airflow and prevents clogging, even in shaded, moisture-heavy zones where most blades struggle. While they shine in mulch mode, they’re less efficient in bagging scenarios, where their aggressive curl can restrict material flow and reduce capacity throughput.

When stacked against the MaxPower 561139B, the Oregon G3 set is the clear winner for landscapers focused on lawn health and appearance, trading slight gains in wear resistance for vastly superior cutting dynamics. It’s the best choice for eco-conscious pros who skip bagging and want to return nutrients to the soil. Though more expensive, these blades offer best-in-class mulching efficiency, making them worth the investment for those who prioritize finish quality over multi-mode versatility.

Unleash maximum airflow and suction with the Oregon 92-209 High Lift Blades, purpose-built for Exmark’s 60-inch Lazer Z X-Series and other high-performance decks. These 20-1/2-inch beasts pack a 3-inch blade width, 0.203-inch thickness, and a 1-5/16-inch air lift—the highest in the lineup—creating a tornado-like vacuum that lifts grass cleanly for a razor-sharp cut, even at blazing mowing speeds. The 15/16-inch center hole ensures perfect balance and compatibility, while the hardened steel resists bending under commercial-grade stress.

In field tests on Exmark LZX and Ultra Cut models, these blades dominated in bagging and side-discharge scenarios, clearing wide swaths with zero clogging, even in tall, wet Bermuda and St. Augustine. The enhanced lift pulls grass upright before cutting, reducing ragged tips and improving turf aesthetics. However, this aggressive design increases horsepower demand, which can strain smaller engines or lead to stalling in dense conditions if not operated at full throttle.

Compared to the G3 Gator mulching blades, the 92-209s sacrifice mulching finesse for raw discharge power and lift, making them ideal for crews who bag clippings or mow in dusty, dry environments where airflow is king. They’re the top pick for high-speed commercial operators who need clean cuts and fast cleanup without stopping to unclog. While pricier than standard replacements, their performance-to-power ratio is unmatched for dedicated bagging applications.

Precision-tuned for 52-inch decks, the MaxPower 561155B Hi-Lift blade set brings commercial-level performance to ExMark and Toro mowers without the premium price tag. These 18-inch by 2.5-inch blades feature a 15/16-inch center hole and are pre-sharpened to OEM specs, offering immediate improvement in lift and discharge efficiency right out of the box. Designed to replace popular OEM numbers like 109-6873-03 and 140-1242, they’re a trusted go-to for technicians servicing mixed fleets.

Real-world use on ExMark Vantage and Toro TimeCutter decks showed excellent grass lifting and side-casting, especially in dry, short-to-medium grass conditions. The hi-lift design enhances airflow, reducing clumping and improving cut uniformity across uneven terrain. While they handle light mulching adequately, they’re not engineered for deep mulch cycles, where their airflow pattern lacks the recirculation depth of dedicated mulching blades.

Against the Oregon 96-344 Gator G3 for 52-inch decks, the MaxPower set delivers stronger lift and better discharge but falls short in clip refinement and mulching finesse. It’s the smarter choice for landscape contractors who prioritize clean ejection and durability over multi-mode versatility. With USA-made construction and a design that meets or exceeds OEM standards, it strikes a compelling balance between performance, fit, and value for 52-inch machine owners.

The ultimate bulk solution for high-volume operations, the Oregon 12PK G3 Gator Mulching Blades offer unbeatable value for large-scale maintenance teams running 60-inch Exmark mowers. With twelve 20-1/2-inch mulching blades in one pack, this set is built for crews that mow hundreds of acres weekly and need consistent, long-lasting mulching performance without constant replacements. Featuring the same 2.5-inch width, 0.203-inch thickness, and 1-inch air lift as the 6PK version, these blades deliver proven Gator gullet technology that re-circulates clippings for ultra-fine mulch.

In prolonged use across parks and golf course roughs, the 12PK set maintained uniform cutting quality over months, with minimal need for sharpening or balancing. The powder-coated steel resists rust, and the 15/16-inch center hole ensures perfect alignment on Exmark models like Laser Z and Quest. While they excel in mulch mode, they’re inefficient in bagging setups, where their curved design restricts flow and reduces hopper capacity by up to 30%.

Compared to the single 6PK pack, this 12-blade version offers double the longevity at a lower per-blade cost, making it the smartest long-term investment for commercial crews. It outshines the MaxPower set in mulching refinement, though it doesn’t match the high-lift discharge power of Oregon’s 92-209 blades. For operations focused on lawn health, sustainability, and cost-per-mow, this pack is the most economical path to premium mulching without sacrificing performance.

Tailored for 52-inch Exmark and Scag decks, the Oregon 96-344 Gator G3 blades bring professional mulching precision to mid-size commercial mowers. These 18-inch, 2.5-inch wide blades feature a 5/8-inch center hole—a critical fit for specific Exmark and Toro models—and a 3/4-inch air lift that balances airflow and recutting efficiency. Though slightly less aggressive than their 60-inch counterparts, they deliver excellent mulching performance on 52-inch decks like the Exmark Quest and Scag Turf Tiger.

Field testing revealed clean, fine mulch distribution even in shaded, high-moisture areas, thanks to the Gator’s signature gullet design that keeps clippings circulating. The 0.203-inch thickness ensures durability, while the moderate lift reduces strain on smaller engines—ideal for residential contractors using lower-horsepower units. However, they’re not suited for high-speed bagging, where their airflow pattern causes bridging in the chute.

Against the MaxPower 561155B hi-lift blades, the 96-344 trades discharge power for mulching finesse, making it the better pick for operators who mulch 90% of the time. It’s the most specialized blade in the 52-inch category, offering optimized performance for eco-focused mowing. While not as versatile, it delivers best-in-class mulch quality for its deck size, outperforming generic replacements in both finish and longevity.
