8 Best Replacement Blades for Toro Lawn Mower (2025 Guide)

When it comes to maintaining that crisp, clean mulch every time you mow, the genuine Toro 22″ Recycler Replacement Blade doesn’t just meet expectations—it defines them. Engineered as a direct OEM match for model 131-4547-03, this tooth mulcher blade delivers aggressive grass lift and precise cutting geometry that keeps clippings circulating under the deck for ultra-fine mulching. With exact specs—21-11/16″ length, 7/16″ center hole, and 0.150″ thickness—this blade ensures perfect balance and fit, eliminating vibration and uneven cuts that plague off-brand alternatives.

In real-world testing across thick Bermuda and damp Kentucky bluegrass, the Toro blade consistently produced even dispersion and superior mulch quality, thanks to its optimized airfoil design and toothed edge that enhances airflow and recutting efficiency. The hardened steel construction holds its edge longer than many aftermarket options, though like all blades, it benefits from seasonal sharpening. It’s especially effective on 22″ Recycler decks where factory-level precision is key, but it struggles slightly in overgrown lots where heavier-duty blades might fare better.

Compared to third-party competitors like MaxPower or UDC, the Toro genuine blade trades a bit of cost-efficiency for unmatched reliability and engineered consistency. It’s the go-to choice for homeowners who treat their mower like a precision tool and want zero guesswork in compatibility or performance. While pricier per unit than multipacks, its perfect OEM alignment and durability make it a smart long-term investment over blades that claim compatibility but sometimes underdeliver.

The MaxPower 331376XB steps into the ring as a budget-savvy contender that doesn’t sacrifice core performance, delivering a commercial-grade mulching blade that holds its own against OEM standards. Designed to replace Toro’s 108-9764-03 and 131-4547-03, this blade features a 21-11/16″ length, 7/16″ center hole, and a powder-coated finish that protects against rust and peels off during first use—revealing a factory-sharpened edge ready for action. Its toothed mulching profile generates strong lift, helping keep clippings in the airflow loop for finer mulch.

During testing on a Toro 22″ Recycler in mixed lawn conditions—from dry fescue to damp St. Augustine—the MaxPower blade delivered solid, consistent performance, producing mulch fine enough to vanish into the turf within days. The steel feels robust under normal mowing, though it’s not heat-treated to the same level as premium blades, so it may dull faster in sandy or debris-heavy yards. It handles standard weekly mowing with ease but shows slight wear after three seasons of heavy use.

Stacked against the genuine Toro blade, MaxPower offers excellent value for the price-conscious DIYer who doesn’t want to compromise on basic fit or function. It’s not quite as precisely balanced as OEM, occasionally introducing minor vibration at high RPMs, but it’s a practical upgrade over worn factory blades. For those replacing blades annually or maintaining multiple mowers, this one delivers reliable performance at a fraction of the OEM cost.

UDC Parts raises the bar for value with its 2-pack Gator-style mulching blades, offering twice the lifespan potential without doubling the cost. These blades are built to replace Toro 131-4547-03 and 108-9764-03 with precision, featuring a 21-11/16″ diagonal length, 2-1/2″ width, and 7/16″ center hole—slightly wider than stock, which enhances lift and mulching action. The air lift of 29/32″ creates strong turbulence under the deck, making it ideal for homeowners who demand thatch reduction and rich soil enrichment from their clippings.

In side-by-side mowing trials, the UDC blades outperformed stock in moist, dense grass, where their wider profile and aggressive curvature kept clippings airborne longer for more recuts. The pre-sharpened edge, protected by a thin paint layer, cuts cleanly right out of the gate, and the hardened steel shows good resistance to nicks from hidden twigs or stones. While slightly heavier than OEM, the balance remains excellent, with no noticeable vibration on standard 22″ decks.

Compared to the single-blade Toro OEM option, the UDC 2-pack is a clear win for long-term value, especially for seasonal users or those with larger lawns requiring frequent mowing. It matches or exceeds the specs of several competitors while offering broader compatibility across 22″ Toro and Lawn-Boy models. For the price, it delivers near-OEM quality with a performance edge, making it a top pick for those who want more blade for their buck.

Grasscool enters the market with a compatibility-first philosophy, crafting a 2-pack of mulching blades that cast an exceptionally wide net across the Toro 22″ Recycler ecosystem. With a 21-5/8″ length, 2-1/4″ width, and 7/16″ center hole, these blades are tuned to fit models from the 20001 to the 21472 series, making them a go-to solution for owners of older or mixed-model fleets. The toothed mulching design and 7/8″ air lift generate strong suction, promoting fine mulch and reducing the need for bagging.

Field testing revealed consistent performance across multiple Toro decks, with clean cuts and minimal clogging, even in slightly overgrown grass. The 5/32″ thickness adds rigidity, helping the blade resist bending during sudden impacts, though it’s not as impact-resistant as heat-treated steel. The paint coating—meant for safety and rust prevention—wears off quickly during first use, revealing a serviceable edge that may benefit from a quick tune-up after break-in.

When compared to the UDC or budrash options, Grasscool’s standout trait is sheer compatibility breadth, covering nearly every 22″ Recycler variant in production. It’s the best choice for landscapers or property managers maintaining multiple mowers across different years. While the edge sharpness isn’t quite as refined out of the box, the versatility and dual-pack format make it a strategic buy for anyone tired of cross-referencing part numbers.

If razor-sharp cutting performance is your top priority, the budrash 2-pack delivers with a focus on precision edge geometry and immediate readiness. These blades feature serrated teeth and dual cutting edges that actively pull grass into the cut, reducing clumping and ensuring a clean, even finish even in damp conditions. At 21-15/16″ long with a 7/16″ center hole, they slightly exceed OEM length, which can enhance overlap and cutting efficiency—but demands careful installation to avoid deck contact.

In real-world use, the budrash blades sliced through thick summer turf with noticeable ease, leaving behind finely chopped mulch that decomposed quickly. The 2-1/8″ width balances lift and drag, making it efficient without overloading the engine. Their standout feature is the factory-sharpened edge, which feels keener than most competitors right out of the package, giving it an edge in initial performance. However, the slightly longer span may cause vibration in older or warped decks.

Against the MaxPower or Ximoon models, budrash wins on initial sharpness and cutting aggression, making it ideal for users who mow weekly and want a crisp, manicured look. It’s less about longevity and more about peak performance at install. For homeowners who prioritize a show-ready lawn over long-term durability, this is the blade that delivers first-cut excellence with strong overall value.

Ximoon’s 131-4547-03 replacement blade stands out with a focus on aerodynamics and operational refinement, offering more than just a metal swap—it’s a performance upgrade for airflow and noise reduction. Built with heat-treated steel for bend resistance, this blade features a 21-11/16″ length and 0.150″ thickness, matching OEM specs while incorporating an optimized blade curvature that enhances air circulation under the deck. This translates to better clipping control, reduced clogging, and quieter mowing—a rare combo in the replacement blade space.

During testing, the Ximoon blade demonstrated superior airflow management, especially on flat or compacted lawns where poor circulation usually leads to clumping. The sharp edge cuts cleanly, and the aerodynamic design helps reduce engine strain, making it a smart pick for older mowers showing signs of wear. It handles standard mowing cycles with ease, though in overgrown or weedy areas, it benefits from slower passes to maintain optimal lift.

Compared to the Toro OEM blade, Ximoon offers similar precision with added engineering enhancements—particularly in noise and efficiency. It’s not as widely compatible as Grasscool or UDC, but for users with common Recycler models, it delivers a smoother, quieter mow with excellent mulching results. If you value refined performance and long-term deck cleanliness, this blade offers a compelling alternative to standard replacements.

Tailored specifically for 21″ Toro Heavy-Duty and Super Recycler models, this 2-pack of 108-3762-03 blades fills a critical niche for owners of older or commercial-grade walk-behinds. With a 21″ length, 2-1/4″ width, and 0.43″ center hole, these blades are engineered to replace OEM numbers 93-4106 and 133-8183-03, fitting models like the 21566, 22280, and 20090 series. The spiral-shaped design enhances cutting efficiency, while the rust-proof coating ensures longevity even in wet climates.

In practical use, these blades delivered consistent, clean cuts across tough grass types, with the spiral edge helping to reduce drag and improve mulch quality. The thickened, reinforced steel resists bending during impact, a common issue in rocky or uneven yards. The coating wears off quickly during first use, revealing a sharp edge that requires no tuning—ideal for users who want install-and-go reliability.

Compared to 22″ models, this blade is a specialist solution—not interchangeable, but perfect for its intended class. For owners of 21″ Toro Recyclers, it offers better availability and value than hunting down OEM parts. While it lacks the broad compatibility of larger models, its precision fit and durability make it the best choice for maintaining peak performance in its specific category.
