Cutlass Lawn Mower Blades of 2026 For Clean Cuts

The Chway 42-Inch Replacement Lawn Mower Blade Set is a heavy-duty replacement option designed specifically for dual-blade 42-inch cutting decks found on many popular riding mowers and lawn tractors. For suburban homeowners with expansive yards, rural property owners managing uneven grassy lots, and budget-conscious DIYers, maintaining sharp, balanced mower blades is one of the most critical steps in lawn upkeep. Dull or nicked blades rip grass rather than cutting it cleanly, leaving ragged brown tips across the yard. This two-piece set provides an accessible way to refresh mower performance before the spring growth rush or mid-summer maintenance cycles.

In terms of cutting performance, these blades feature an aerodynamic curved contour paired with a 1-1/8-inch high-lift profile. Based on product specifications, this shape is engineered to generate a continuous vortex of air under the mower deck while the blades spin. This strong upward draft pulls grass blades straight for a level, uniform cut, then repeatedly circulates clippings across the cutting edges to shred them into finer particles. The resulting fine mulch decomposes more rapidly back into the turf to deliver nutrients, while those who bag their clippings will appreciate the improved air velocity that helps pack bags more efficiently with fewer deck clogs.

Build quality centers on high-strength steel that undergoes an advanced heat-treatment process to balance surface hardness with impact resistance. Measuring 21-3/16 inches in length, 2-3/8 inches in width, and 0.16 inches in thickness, each blade provides the mass needed to power through dense turf, field weeds, and thick spring overgrowth without excessive flexing. The blades arrive with a dark protective paint coating that shields the metal from moisture and corrosion during transit and storage. While this coating covers the cutting edge initially, it quickly wears away during the first mowing session, revealing the honed steel underneath.

Routine installation is straightforward for anyone familiar with basic tractor maintenance. The blades feature a dedicated 6-point star center hole engineered to mate cleanly with compatible spindle shafts on brands such as Troy-Bilt, Cub Cadet, Craftsman, and MTD. Because proper fit is vital for safety and smooth operation, checking the tractor spindle shape prior to purchase is essential. Taking basic safety steps, such as wearing heavy work gloves, securing the cutting deck, and blocking the blades with a scrap piece of wood during bolt tightening, makes seasonal blade replacement a manageable garage or driveway project.

While these blades offer dependable durability and strong airflow, buyers should consider a few practical factors. They are not universal blades; mowers requiring round center holes, 5-point stars, or 'S' shaped hubs will not accept them. Additionally, some lawn care enthusiasts who prefer razor-sharp edges right out of the box may choose to lightly hone the painted cutting bevel prior to the first spin. Overall, for property owners looking for an affordable, heavy-duty replacement set to restore their 42-inch deck to clean-cutting condition, this package provides exceptional utility and dependable lawn care results.

Ensuring correct fitment is the most critical step when replacing riding mower blades. This Chway set is built to replace OEM numbers 942-04308, 942-04308A, 942-04312, 742-04308, 742-04312, and related variants. It is compatible with a wide assortment of 42-inch lawn tractors, including Troy-Bilt Bronco, Pony, and Mustang models; Cub Cadet XT1, XT2, and RZT series; as well as numerous Craftsman T-series and LT-series mowers.

The key identifier is the 6-point star center mounting hole. Homeowners should verify their mower spindle shape before ordering, as installing a star blade on an incompatible spindle can damage the deck mandrel or cause dangerous vibration. When properly matched, the star pattern locks firmly into place, minimizing slipping under heavy cutting loads and ensuring a secure connection throughout the mowing season.

A mower blade does far more than simply slice grass; its aerodynamic shape dictates how grass clippings move inside the deck. With a 1-1/8-inch lift wing on the trailing edge, these blades create significant suction that lifts bent grass blades upright right before the cutting edge makes contact. This provides a noticeably crisper cut along front walkways, fences, and open turf.

That same airflow plays a major role in waste handling. When mulching, the high-lift wings circulate clippings back through the blade path repeatedly until they are reduced to tiny flecks that settle invisibly into the soil. When using a collection system, the enhanced airflow drives grass directly up the discharge chute, reducing clogs in damp conditions and filling collection bags more completely for fewer disposal trips.

If you're maintaining a 42-inch riding mower, the budrash gator mulching blades are a practical replacement option. They're designed for popular models from Cub Cadet, Troy Bilt, MTD, and Craftsman, among others. These blades are best suited for homeowners who want a balance of performance and value without paying premium prices for OEM parts.

In real-world use, the high-lift design pulls grass up for a clean, even cut, while the mulching teeth continuously chop clippings into fine particles. That means less raking and a healthier lawn. Installation is straightforward – just remove the old blade, match the 6-point star center hole, and torque it down. Most people can do it in under 10 minutes with a socket wrench.

Build quality is respectable for the price. The heavy-duty steel holds up well against normal mowing conditions, including light rocks and roots. However, the blades may dull faster than some premium options if you're regularly cutting thick or wet grass. It's a good idea to check and sharpen them mid-season if needed.

One realistic limitation is that compatibility is not universal. You must measure your existing blade and confirm the hole shape is a 6-point star. The dimensions are 21-1/4 inches long, 2-3/8 inches wide, and 0.157 inches thick. If your mower uses a different pattern, these won't fit.

Overall, the budrash gator mulching blades offer a reliable, cost-effective solution for maintaining your lawn. They're a smart buy for DIYers who want decent performance without overspending. Just double-check your specs before ordering, and you'll be mowing in no time.

Compatible with many 42-inch deck mowers including Cub Cadet 1170, 1600, LT-1040, LT-1042, LTX-1040; Craftsman 604G, LT-1500, LT-2000, T1000; Troy Bilt 604G, 609G, Bronco, Bronco 42 Auto, Bronco 42X Auto; Huskee 606G, 608G, 660G, 673G; and others. Always verify your mower's deck size and blade mounting pattern before purchase.

The MaxPower 561532B blade set is a direct replacement mulching kit designed for 42-inch riding mowers and lawn tractors built by MTD, Cub Cadet, and Troy-Bilt. Tailored for homeowners managing standard yards as well as property owners maintaining rougher acreage, these blades convert side-discharge or mulching decks into efficient grass-chopping setups. Each blade in the two-piece set measures 21-3/16 inches long by 2-3/4 inches wide, utilizing a standard 6-point star center hole pattern.

In real-world lawn maintenance, cutting performance hinges on lift and airflow. These blades feature an aggressive serrated rear sail that creates strong vacuum inside the deck housing. The suction pulls turf blades upright just before the cutting edge strikes, resulting in clean, uniform passes without leaving behind uneven streaks or uncut seed heads. The recirculated clippings get repeatedly driven against the mulching teeth, chopping them into fine particles that settle deep into the turf canopy instead of forming dense clumps on the surface.

Durability is where this set stands apart from lightweight generic options. Manufactured in the USA from heavy-gauge carbon steel, the blades display the rigidity needed to survive occasional contact with hidden pinecones, small twigs, and exposed roots. They come factory balanced, which is crucial for reducing high-speed vibration that can loosen deck hardware or prematurely destroy spindle bearings. At roughly five pounds for the pair, they carry substantial rotating inertia that powers through patches of tall, thick fescue or bluegrass.

There are a few practical considerations to keep in mind before mounting. Like many commercial replacement blades, these arrive with a thick layer of black powder coating covering the cutting bevel. While this protects the steel from rust during shipping and storage, scraping or filing off the finish on the cutting edge gives you an immediate boost in sharpness. Additionally, compatibility is strictly limited to 6-point star shafts, so owners of decks with splined, triangular, or circular center holes must look elsewhere.

For anyone running a 42-inch rider looking to restore cutting efficiency without paying dealership prices for OEM replacements, the MaxPower 561532B set is a solid, hardworking pick. The combination of durable domestic steel, solid mulching geometry, and tight spindle fitment makes seasonal deck maintenance straightforward and rewarding.

Confirming your spindle pattern and deck size is essential before swapping blades. This set is engineered specifically for 42-inch cutting decks featuring a 6-point star spindle interface.

Direct OEM Cross-References:

- MTD / Cub Cadet / Troy-Bilt: 742-04126, 742-0616, 742-0616A, 942-04126, 942-0616A

- Craftsman: CMXGZAM110115

- Windsor: 50-3945, 50-3950

Check the bottom of your existing spindle or the underside of your old blades to verify the 6-point star shape before ordering. These will not seat properly on round-center, 5-point star, or 'S' shape spindles.

The DECKMAN 3-Piece X-Blade Dual Mulching Blade Adapter set is a dedicated mounting accessory engineered to configure dual cutting blades on standard commercial lawn mowers. Designed with a 2.8-inch width, a 0.12-inch thickness, and a round 5/8-inch center hole, each adapter plate securely positions a primary blade and a secondary cover blade at a precise 90-degree angle. By stacking two blades per spindle in an X-configuration, this setup enables standard commercial decks to grind grass clippings into significantly finer mulch before discharge.

This adapter kit is best suited for commercial landscape contractors, groundskeepers, and property owners operating three-blade commercial zero-turn, stand-on, or walk-behind mowers. The three-piece package corresponds to the manufacturer XB3 designation, making it an appropriate choice for triple-spindle deck layouts. Homeowners and professionals looking to eliminate visible grass windrows, reduce seasonal leaf volume, and avoid frequent bagging will find the dual-blade concept advantageous, provided their machine utilizes standard round 5/8-inch spindle shafts.

From a construction and mechanical standpoint, each bracket is finished in a clean silvery coating and built from rigid 0.12-inch thick material to withstand the rigors of heavy mowing. The manufacturer highlights that the adapter maintains alignment across the spindle assembly, which prevents blade slippage under heavy cutting resistance. Eliminating slippage is critical because slipping blades can over-torque spindle mounting bolts, leading to stripped hardware or frozen bolts that become exceptionally difficult to remove during seasonal sharpening.

Practical ownership requires confirming physical fitment before mounting. Operators must verify that both their spindle shafts and their selected replacement blades share the exact 5/8-inch center hole geometry. Because stacking two commercial blades and an adapter increases the overall mounting stack height, buyers should also inspect spindle bolt length to verify adequate thread engagement. Equipment service should always be performed with the engine disabled, the spark plug disconnected, and in accordance with manufacturer torque specifications.

While the DECKMAN adapters deliver an economical pathway to intensified mulching, realistic limitations remain. The set includes only the three adapter brackets, meaning all primary blades, secondary blades, and spindle bolts must be verified or sourced independently. Furthermore, mowers with proprietary star-shaped or hex center holes cannot accept this standard round mounting design. For operators running commercial equipment with standard 5/8-inch spindles who want cleaner turf without bagging, this three-piece kit offers a durable, practical upgrade.

Compatibility for the DECKMAN X-Blade adapters centers entirely on spindle shaft dimensions and deck configuration. Each adapter features a standard 5/8-inch round center hole and a 2.8-inch width, designed specifically to mount onto commercial-grade spindles that share this hardware diameter. The three-piece quantity aligns directly with three-blade commercial mower decks, matching the manufacturer XB3 configuration.

Equipment owners should inspect both their mower spindles and replacement blades before purchasing. These adapters do not fit proprietary 5-point star, 6-point star, or splined spindle shafts. In addition, because stacking two blades increases the total thickness on the spindle shaft, buyers should ensure their existing spindle bolts provide sufficient thread engagement or acquire appropriate length commercial mounting bolts.

The X-Blade dual-blade concept operates by mounting a standard cutting blade alongside an auxiliary cover blade at a perpendicular 90-degree angle. As the spindle rotates, the primary blade provides the initial cut while the secondary blade recuts the suspended clippings, generating finer organic material that decomposes rapidly back into the turf.

Beyond improving clipping reduction, the DECKMAN adapter physically locks the two blades together to prevent them from rotating out of alignment. This prevents blade slippage against the spindle face, which stabilizes deck balance, reduces unnecessary vibration, and stops the spindle bolt from over-torquing during demanding commercial cutting tasks.

If you own a 42-inch riding mower from Cub Cadet, Craftsman, Troy-Bilt, MTD, or several other brands, chances are you have been through the cycle of replacing dull blades at the local big box store. The UDC Parts 942-0616A set offers a practical alternative that many users swear by. These are gator-style mulching blades designed to lift grass aggressively and chop clippings into fine bits, leaving a manicured look without clumps or piles.

Who should buy these blades? Homeowners with a few acres of lawn will appreciate the time saved by not having to bag clippings. The mulching action is effective enough that you can often skip a second pass. DIYers who maintain their own equipment will find the installation straightforward: just match the six-point star center hole and the three-inch width. The blades are heat-treated and balanced from the factory, which contributes to a noticeably quieter mowing experience. One long-term review mentioned that the noise dropped from a chainsaw-level roar down to a soft hum.

In real-world use, the cutting performance is a clear step up from standard OEM blades. Grass is sliced cleanly, and there is no tearing or browning after a few days. The blades handle slightly overgrown conditions without bogging down. However, because the gator design creates a strong lift, it will pull up sand and small debris if you get too close to bare soil or a garden hose. That is a tradeoff for the superior mulching capability. Build quality feels solid, with the blades weighing a bit more than stock, which suggests they will last through multiple seasons of regular mowing.

One limitation to keep in mind: compatibility lists are long, but different trim levels of the same mower model may use different blades. Always confirm your mower's complete model number before buying. The packaging includes two blades, which is perfect for most 42-inch decks that use a two-blade setup. You get a spare or can replace both at once. Considering the price point, these blades offer exceptional value compared to OEM replacements. If you want a better cut, less noise, and less time spent on lawn cleanup, the UDC Parts 942-0616A blades are a solid choice.

Blade Length: 21-3/16 inches (measured diagonally). Blade Width: 3 inches. Blade Thickness: 0.156 inch. Center Hole: 6-point star. Side Hole: 5/16 inch. Center-to-Center Outside Hole: 2-1/2 inches.

The Genuine Krone Disc Mower Blade Set from S&H PARTS is a must-have replacement kit for anyone running Krone AM, AMR, AMT or EasyCut disc mowers. This 20-pack includes exactly 10 clockwise and 10 counter-clockwise blades, each measuring 4x50x118mm to match OEM specs. If you're a farmer, rancher, or property manager who depends on precise cutting for hay or pasture maintenance, having a fresh set of blades is critical to keeping your mower performing at its best.

In real-world use, these blades cut cleanly through heavy grass and light brush without excessive vibration. The hardened steel resists chipping from rocks and other field debris, so you can keep mowing longer between replacements. The balanced CW/CCW design ensures even wear across the entire mower deck, which helps maintain consistent cutting height and reduces strain on your PTO driveline. That translates to better hay quality and fewer headaches during harvest season.

Build quality is what you'd expect from genuine Krone-spec parts: precise stamping, uniform thickness, and sharp edges that stay sharp through several acres. Installation is straightforward if you have a socket set and torque wrench, but note that no bolts or instructions are included. You'll need to reuse your existing hardware or buy new bolts to spec. The set is priced higher than generic options, but the exact fit and durability often mean fewer replacements and less downtime over the long haul.

One realistic drawback is compatibility: these blades are designed specifically for Krone disc mowers listed in the title. They won't work with other brands like John Deere or Kuhn without modification. Also, the lack of hardware might be a minor inconvenience if you're in a hurry to get back to mowing. For most operators, the peace of mind that comes with genuine parts outweighs these small trade-offs.

Overall, if you own a compatible Krone disc mower and you value cutting performance, reliability, and long blade life, this S&H PARTS blade set is a solid investment. It's an ideal stock-up purchase for the start of the season, giving you a full set of spares for quick field repairs. For commercial hay producers or large-acreage owners, having these on hand means less downtime and more consistent results.

The balanced CW/CCW set makes it easy to swap blades across multiple rotors without having to sort them out individually.

The Troy-Bilt Original Equipment High-Lift Blade Set (OE# 742P05177) is a specialized two-piece replacement blade assembly built for 42-inch riding lawn tractors and Mustang zero-turn mowers. Designed with deep, aggressive rear lift wings, these blades focus on maximizing air circulation under the cutting deck. This design makes them particularly valuable for suburban homeowners, rural property owners, and lawn care enthusiasts who regularly manage thick turf, tall spring grass, or heavy leaf fall across medium-to-large yards.

In practical lawn maintenance, the primary advantage of high-lift blades lies in their grass-handling mechanics. As the blades spin, the angled airfoils create a vacuum effect that pulls leaning grass blades upright just before the cutting edge strikes. This creates a crisp, level surface across the lawn and sends clippings flying forcefully out of the side discharge chute. For homeowners who rely on a rear bagger, this elevated airflow packs clippings tightly into collection bags without jamming the discharge chute, even when mowing slightly damp turf after morning dew.

Build quality matches factory original standards, utilizing hardened steel treated with a protective black finish to resist corrosion and outdoor wear. Each blade measures 22 inches in length to provide a complete 42-inch cutting swath when paired together. The patented S-shaped center mounting hole corresponds exactly to factory Troy-Bilt spindle shafts, ensuring that the blades seat securely without slipping or introducing dangerous deck wobble during high-speed rotation.

Routine installation is straightforward for anyone familiar with basic riding mower maintenance. Swapping out worn or nicked blades requires standard shop tools to loosen the spindle hardware, clean the underside of the deck, and torque the new blades into place. Keeping a sharp, balanced set of blades on your mower protects the spindle bearings from unnecessary stress, reduces fuel consumption by letting the engine turn with less resistance, and prevents frayed, brown grass tips on your lawn.

Before purchasing, it is essential to verify that your specific mower deck uses the S-shaped center hole rather than a star or round pattern. Additionally, while these blades excel at bagging and side discharge, homeowners who prefer fine mulching should consider a dedicated mulching kit instead. For those seeking dependable bagging performance, clean discharge lines, and reliable factory fitment, this high-lift set serves as a top-tier replacement for seasonal yard upkeep.

Replacing lawn mower blades is an essential part of regular spring tune-ups and seasonal maintenance. Before starting, always park the mower on a level surface, engage the parking brake, remove the ignition key, and disconnect the spark plug wire to prevent accidental starting. Wearing heavy leather work gloves is strongly recommended to protect hands while handling sharp edges.

With the deck safely elevated or removed, block the blade with a piece of scrap wood to keep it from turning while loosening the spindle bolt. Inspect the spindle shaft for debris or grass buildup before installing the new Troy-Bilt blades. Align the S-shaped center hole precisely with the spindle pattern, ensure the curved wings point upward toward the deck housing, and tighten the mounting hardware to the manufacturer-specified torque rating for safe operation.

High-lift blades are engineered specifically to overcome common bagging and discharge frustrations. Standard blades often lack the aerodynamic lift required to throw heavy clippings through long discharge chutes, resulting in clumping under the deck and frequent blockages that require stopping the engine to clear manually.

By generating continuous high-velocity airflow under the 42-inch deck, these Troy-Bilt blades keep clippings suspended until they exit cleanly into the grass collection system or spread evenly across the lawn. This suction also aids in picking up fallen leaves in the autumn and removing weed seed heads during routine weekend mowing, leaving a clean, manicured finish across your turf.

The QWD 942-04308A Mower Blade 2-Pack is a replacement cutting set engineered for lawn tractors and residential zero-turn mowers with 42-inch cutting decks. This set is primarily aimed at suburban homeowners, rural property caretakers, and DIY lawn enthusiasts who depend on reliable machines like the Cub Cadet XT1, Craftsman T110, or Troy-Bilt Pony for routine yard maintenance. Replacing worn, nicked, or unbalanced blades is essential for preserving lawn health, and this affordable pair offers an accessible solution for seasonal deck refurbishment.

In terms of cutting performance, these blades feature a prominent high-lift profile. The raised wings on the trailing edge generate elevated aerodynamic suction inside the mower deck, which lifts bent or trampled grass blades upward immediately before the cutting edge strikes. This vacuum effect results in a cleaner, more uniform trim across the turf, preventing the frayed, brown tips often caused by dull or low-lift blades. Homeowners who frequently bag their clippings or rely on side discharge during vigorous spring growth will appreciate the extra throwing power, which helps prevent deck clogging and messy grass clumps across the lawn.

Built with durable steel measuring roughly 5/32-inch thick and around 2-1/2 inches wide, each blade measures approximately 21-1/4 inches long to cover a standard two-blade 42-inch deck. The central mounting point uses a precise 6-point star design, which is engineered to mesh securely with matching spindle shafts found on many MTD-built riding mowers. This snug fit helps eliminate blade slip and limits deck vibration during operation, protecting your mower deck bearings and spindle assemblies from premature wear.

Deck maintenance and installation remain practical for any homeowner comfortable with basic garage tools. Swapping out old blades typically requires dropping the mower deck or driving the front onto service ramps, securing the blade with a wooden block, and loosening the spindle nut. The 6-point star pattern ensures immediate alignment upon reinstalling, eliminating guesswork during mounting. Homeowners preparing for the spring mowing rush or cleaning up turf after hitting hidden yard debris will find this a quick, manageable weekend task.

As with any replacement hardware, there are practical factors to consider before purchasing. These blades strictly fit 6-point star spindle shafts, meaning they will not fit mowers utilizing round or triangular center holes. In addition, the increased airflow of a high-lift design demands slightly more engine horsepower in overgrown or wet grass, and some users may prefer to sharpen the factory edge slightly before initial use. For suburban residents looking for dependable bagging performance and a clean cut ahead of backyard barbecues, this 2-pack serves as an economical, practical choice.

The high-lift wing profile creates substantial upward suction, standing up flat grass for a clean, even top cut. This aerodynamic force accelerates grass clippings through the discharge chute, reducing deck clogging during heavy spring growth.

For owners who use collection systems, the elevated airflow packs clippings tightly into grass catcher bags for fewer emptying stops. While not designed strictly for micro-mulching, the strong lift delivers tidy results for both standard side discharge and bagging routines.

Installing these replacement blades requires checking that your mower features a matching 6-point star spindle shaft. Disconnect the spark plug wire and secure the cutting blade with a wooden block against the deck housing before removing the mounting bolt.

Always verify blade orientation so the curved lift wings face upward toward the deck housing rather than toward the grass. Checking deck balance and torque specifications helps maintain smooth operation and reduces vibration across the mowing season.

The 8TEN LawnRAZOR Notched High-Lift Mower Blade set is an aftermarket replacement kit designed specifically for 42-inch mower decks. Engineered to replace common original equipment parts from brands like Husqvarna, Poulan, AYP, and Ariens, this two-blade pack directly targets homeowners seeking to revive their cut quality without paying premium dealership prices. Whether you are maintaining a wide suburban lawn or managing a rural property, replacing worn or bent blades is one of the most effective ways to restore proper deck operation.

In practical lawn maintenance, high-lift blades excel at generating significant air velocity under the cutting deck. The distinct rear sail and notched edges draw limp grass upright before the cutting edge makes contact, resulting in a consistent, manicured look across the entire yard. This enhanced suction works exceptionally well for bagging clippings during peak growing season or propelling damp discharge out of the chute to prevent clumping. Suburban lawn owners preparing their turf for weekend barbecues will appreciate the clean lines and reduced need for rake cleanup.

Build quality centers on resilient steel stock with a total package weight of nearly four pounds. The blades come finished with a durable green powder coating that guards against surface corrosion while sitting in humid garden sheds or garages between mowings. While the factory edge provides a dependable working sharpness out of the box, some lawn care enthusiasts may prefer a quick touch-up with a file for an ultra-sharp cut before mounting them to the deck spindles.

Swapping out blades is a manageable seasonal task for DIY homeowners. Because this package includes a matched pair, replacing both sides simultaneously ensures smooth deck rotation and minimizes spindle vibration. As long as users disconnect the spark plug wire and secure the deck properly before wrenching, installation is straightforward. Routine maintenance involves periodic checks for nicks after hitting hidden rocks, alongside standard end-of-season sharpening.

Realistic limitations relate primarily to your specific yard conditions and deck setup. Because these blades generate strong upward suction, mowing on parched ground or sandy soil can throw up extra dust and debris. Additionally, while they handle heavy bagging and side discharge admirably, dedicated mulching setups may require standard or specialized mulching blades to achieve powder-fine clippings. For general weekly mowing and bagging duties, however, this set provides an affordable and reliable refresh for your riding mower.

The notched high-lift profile on these 8TEN blades is built to optimize air movement beneath standard 42-inch mower decks. By pulling grass blades vertically before shearing, the cutting deck leaves behind fewer missed strands and prevents the uneven patches often caused by bent or dull factory blades. Homeowners tackling fast-growing spring grass will find the extra lift helpful in keeping discharge chutes free from wet blockages.

When paired with a rear bagging attachment, the suction generated by high-lift wings drives clippings and chopped leaves directly into the collection bins with fewer clogs in the discharge chute. This efficient airflow also helps disperse heavy clippings evenly when side discharging, preventing thick clumps from smothering green grass during regular weekend cuts.

This blade set is engineered as a direct replacement for standard 42-inch riding mowers and lawn tractors built by AYP, Husqvarna, Poulan, Craftsman, and Ariens. It replaces OEM part numbers including AYP 138498, 134149, and 127843, along with Husqvarna numbers 532138498 and 532127843. It fits popular riding tractor models such as the Husqvarna YTH series, Poulan PB models, and corresponding lawn tractors.

Before purchasing, homeowners should verify their mower deck width and check the center mounting hole against their existing spindle shaft. Installing properly matched blades protects the spindle bearings from unnecessary stress, prevents blade overlap collisions, and ensures a level cut across the entire mowing path.
