6 Best Lawn Mower Blades for Scag (2025 Guide)

For those who need value without sacrificing function, the Belleone 482878 blades are a game-changer—especially when stocking up for a full mowing season. These high-lift steel blades deliver solid airflow and clean cutting performance across 52″ Scag decks, thanks to their 1-inch air lift and 18-inch length, keeping clippings moving efficiently even in dense grass. Their 6-pack format makes them a smart buy for crews or frequent mowers who can’t afford downtime waiting for replacements.

During extended use on Scag Tiger Cub and Turf Tiger models, the blades held up well under daily commercial stress, maintaining sharpness longer than expected for the price. The 2.5-inch width and 1/5-inch thickness provide adequate rigidity, though they’re slightly thinner than premium options, which becomes noticeable when mowing tall, wet grass—occasional clogging may occur. Still, the noise and splash reduction design is a subtle but appreciated touch, making operation quieter and cleaner around sensitive landscapes.

While not as robust as Oregon’s thicker blades, the Belleone set punches above its weight in affordability and fitment accuracy. They’re a budget-savvy alternative to pricier OEM or branded blades, especially when replacing multiple units at once. For 52” decks on Scag and Ferris mowers, they offer solid performance at a fraction of the cost of high-end competitors, making them best for cost-conscious operators who still want dependable results.

When it comes to 61-inch decks, the 8TEN LawnRAZOR toothed blades stand out with a precision-cutting, serrated edge that slices through thick, unruly grass like a hot knife through butter. At 21 inches long with a 0.203-inch thickness, these blades are built tough for commercial mowers like the Scag Wildcat and Husqvarna iZ6125, delivering aggressive cutting action and excellent lift for flawless discharge. The toothed design is a game-changer for operators dealing with overgrown lawns or wet conditions where traditional blades struggle.

In field tests on Scag Advantage and Wright 61-inch standers, these blades excelled at reducing clumping and improving mulching efficiency, thanks to their enhanced turbulence and cutting precision. The 5/8-inch center hole and 2.5-inch width ensure a secure fit and optimal balance, minimizing vibration even at high RPMs. However, the aggressive teeth require more frequent sharpening, and improper balancing can lead to noticeable deck shake—so a blade balancer is highly recommended.

Compared to standard high-lift blades, the LawnRAZOR offers superior cutting performance but demands more maintenance. It’s the go-to choice for landscapers who prioritize clean, aggressive cutting over low upkeep. For 61″ Scag and Ferris decks, these outperform flat-edge blades in tough mowing conditions, though they require more care than smoother alternatives like Oregon’s 91-626.

Oregon’s 91-626 blades are the gold standard for 61-inch commercial mowers, combining rugged durability with precision engineering that stands up to relentless daily use. At 21 inches long and 0.203 inches thick, with a 1-inch air lift, these high-lift blades generate powerful airflow to keep decks clean and grass standing tall—critical for achieving a flawless cut on Scag Turf Tigers and Ferris Z-turns. Their hardened steel construction resists bending and fracturing, a major win for crews mowing rocky or uneven terrain.

Real-world performance on 61″ Scag and Simplicity decks proves these blades maintain sharpness longer than most competitors, handling everything from dry Bermuda to wet St. Augustine without clogging. The 2.5-inch width and 5/8-inch center hole ensure a snug, balanced fit, minimizing vibration and wear on spindles. That said, they’re not designed for mulching—discharge is excellent, but they don’t recirculate clippings as effectively as gator-style blades.

Pitted against toothed alternatives like the 8TEN LawnRAZOR, the 91-626 offers better durability and easier maintenance, making it ideal for high-mileage operations. It’s the top pick for Ferris and Scag 61” decks where reliability and longevity matter most. While pricier than generic sets, these deliver unmatched resilience and consistent performance, outlasting cheaper options by a wide margin.

For 48-inch Scag decks, the Oregon 91-620 is a powerhouse of precision and strength, engineered to dominate commercial mowing cycles with unwavering reliability. With a 16.5-inch length, 0.250-inch thickness, and 2.5-inch width, these are among the thickest, most rigid blades available—perfect for handling heavy-duty cutting without flexing or warping. The 1-inch air lift ensures strong vacuum action, lifting grass cleanly for a uniform cut across all Scag 48” models, including the Hustler 601123 and Lesco 21871.

In real-world use on Scag 48110 and 482877-compatible decks, these blades showed exceptional resistance to impact damage, surviving encounters with hidden debris that would bend lesser steel. The thick profile maintains balance well, but due to their mass, any imbalance is more pronounced—so proper installation is key. They excel in side discharge and bagging applications but aren’t optimized for mulching, where finer recutting is needed.

Compared to the thinner 91-626, the 91-620 trades a bit of weight for unmatched rigidity, making it the best choice for 48” Scag mowers facing tough terrain. It outperforms lighter blades in durability and cut consistency, especially under constant commercial use. For operators who need bulletproof performance on 48-inch decks, this set delivers where it counts—without the maintenance hassle of toothed blades.

The Oregon G5 Gator blades redefine mulching performance for 48-inch Scag decks, transforming clippings into fine, lawn-nourishing mulch with every pass. At 3 inches wide and 16.5 inches long, with a curved, high-lift design, these blades create intense airflow that recirculates grass for multiple cuts—ideal for eco-conscious mowers who skip bagging. The 0.203-inch thickness and 1-inch air lift strike a perfect balance between durability and lift, ensuring excellent cut quality and deck cleaning.

In testing on Scag 48110 and 482877 models, the G5 blades delivered lush, even mulch distribution, even in dense growth, outperforming flat blades by a wide margin. Their aggressive curl enhances turbulence, but this comes at a cost: they require more engine power and can struggle in very tall or wet grass where discharge may slow. Still, for regular maintenance mowing, they’re unmatched in mulching efficiency.

Compared to standard high-lift blades like the 91-620, the G5 sacrifices raw discharge speed for superior mulching—making it ideal for residential pros and property managers who prioritize lawn health. For 48” Scag mowers used in mulching mode, these are the clear winner, offering best-in-class recutting and nutrient return, even if they demand a bit more from the engine.
