Authentic 4pcs Mower Blade of 2026 for Clean Cuts

The MaxPower 561739B is a 2-blade replacement set designed for 46-inch cut riding mowers from Craftsman, Husqvarna, and Poulan. It’s a straightforward upgrade for homeowners who want to restore a clean, even cut without shelling out for expensive OEM parts. These blades measure 23 inches long and 2-3/4 inches wide with a 5-point star center hole, and they replace common OEM numbers like 405380 and 532405380. Before buying, it’s crucial to verify that your current blade’s OEM number matches one of those listed – otherwise fitment isn’t guaranteed.

This set is best suited for DIYers and homeowners who mow a standard residential lawn. It’s not for commercial landscapers logging hundreds of hours, but for weekly cuts on a couple of acres, it’s more than capable. The blades come pre-sharpened with a temporary powder coating that flakes off during the first pass, leaving a razor-sharp edge. In real-world use, that edge slices through thick grass and even light weeds without leaving stragglers or clogging the deck. Owners with bumpy or sandy yards report that the blades hold up well and maintain a good cut over several uses.

Build quality is solid for the price. MaxPower manufactures these in the USA using heat-treated steel, and they feel balanced right out of the box. Installation is simple – bolt them onto the spindle with no special tools needed. The 5-point star hole lines up perfectly on most compatible spindles, and the blades weigh about 2.4 pounds each, which adds enough inertia for good lift and discharge. They’re not the thickest or heaviest blades on the market, but they strike a nice balance between durability and ease of spinning.

One realistic limitation is that they won’t last forever. Some users note needing to replace them once per season if you mow frequently or in rough terrain. That’s pretty typical for blades in this price bracket, and the trade-off is significant cost savings – around half the price of equivalent OEM blades. Also, because fitment depends on a specific OEM number, it’s worth pulling off your old blade to verify the number before ordering. That minor extra step prevents returns.

Overall, the MaxPower 561739B set is a smart buy for anyone with a 46-inch Craftsman, Husqvarna, or Poulan mower who wants reliable cutting performance without overspending. It’s easy to install, sharp, and built well enough for regular homeowner use. You get a great cut at a fraction of the cost, and the Made in USA label adds a nice touch of confidence. For most DIYers and weekend mowers, this is a no-brainer replacement blade set.

Grasscool's 42-inch mulching blade set is a direct replacement for Craftsman, Husqvarna, and Poulan riding mowers with a 5-point star mounting pattern. Designed for homeowners and DIYers who maintain large lawns, these blades aim to deliver better mulching and bagging compared to standard OEM options. The set includes three blades that fit decks with a 42-inch cutting width, making them a practical upgrade for tractors like the LT1000, LT2000, and similar models.

In real-world use, the Grasscool blades cut cleanly and mulch grass into fine clippings that decompose quickly. The high-lift wings create strong airflow, which improves bagging performance and reduces the chance of clogging in wet or thick grass. Several reviewers note that the blades are thicker and heavier than original equipment, which translates to better durability on bumpy terrain. They arrive sharp enough for immediate use, though some users still touch up the edge for a razor finish.

Build quality is solid for the price point. The blades are made from hardened steel with a thick black coating that resists rust. They pass factory balance and hardness tests, so you can install them without worrying about vibration. While they are manufactured in China, the overall craftsmanship impresses most owners. The main drawback is compatibility: you must have the 5-point star hole pattern. If your mower uses a 6-point star, these won't work. Additionally, the blades may dull faster on sandy or rocky soil, but regular sharpening extends their life.

Overall, the Grasscool 42-inch mulching blade set is a smart buy for anyone looking to save money without sacrificing cut quality. They are especially suited for homeowners who mow regularly and want a durable, balanced blade that handles mulching and bagging equally well. If you can confirm your mower's mounting pattern, these blades offer reliable performance and excellent value.

These blades fit Craftsman, Husqvarna, Poulan, and Poulan Pro riding mowers and zero-turn mowers with 42-inch cutting decks that use a 5-point star mounting pattern. Compatible models include Craftsman LT1000, LT2000, Husqvarna YTH series (2009 and newer), RZ series zero-turns, Poulan PB19H42YT, PB20H42YT, and many others.

The KOFINAM 2 Pack Replacement Lawn Mower Mulching Blades are a practical choice for homeowners and DIYers who maintain a 42-inch deck mower. These blades are designed to replace OEM parts on Cub Cadet, MTD, and Troy Bilt models, including popular series like the XT1, XT2, LT42, LTX1040, and RZT-L42. If you have one of these mowers and want to improve your lawn's health with fine mulching, this set is worth a look.

In real-world use, these blades do a solid job of chopping grass clippings into tiny pieces that break down quickly, returning nutrients to the soil. The mulching design works best with regular mowing, keeping clippings from clumping on the lawn. The 21-1/4-inch length and 2-3/8-inch width match OEM specs, and the 6-point star center hole ensures a snug fit on the spindle, reducing wobble and vibration during operation. Installation is straightforward with basic tools, though you might want to balance them for the smoothest cut.

Build quality is decent for the price. The steel feels sturdy enough for typical residential lawns, handling thick grass and light debris without bending or dulling prematurely. The black finish resists rust reasonably well, though it will wear over time. One limitation is that these are strictly mulching blades, so they won't work well with bagging or side discharge setups. If you switch between modes, you'll need to swap blades.

For the average homeowner with a 42-inch deck, this two-pack offers great value. You get a spare blade or a complete set, which extends the time between replacements. The 6-month warranty adds a layer of confidence, though most users won't need it. Just keep in mind that you may need to check balance before the first use, as some sets can be slightly off from the factory.

Overall, the KOFINAM mulching blades are a reliable, cost-effective upgrade for maintaining a healthy lawn. They're best for DIYers who mow weekly and want to skip bagging, not for commercial landscapers who need heavy-duty, all-purpose blades. If your mower is on the compatibility list, this set is a smart buy.

The Grasscool GY20850 mulching blades are a direct replacement for John Deere 42-inch deck riding mowers that use a 7-star mounting pattern. If you own a D100, D105, D110, D125, D130, LA series, or similar model, these blades are designed to fit without any guesswork. They replace OEM numbers GX22151 and GY20850, so you can be confident in compatibility as long as your mower uses the star-shaped center hole.

These are toothed mulching blades, meaning they have serrated edges that chop grass clippings into fine pieces. That helps them settle into the lawn and decompose quickly, returning nutrients to the soil. In real-world use, they deliver a clean, even cut that leaves your yard looking well-manicured. Several reviewers mention the lawn looks noticeably better after switching to these blades, and the mulching action is efficient enough to reduce the need for bagging.

Build quality is solid. The blades are made from alloy steel and measure 21-3/8 inches long, 2-1/2 inches wide, and 5mm thick. That thickness gives them a heavy-duty feel that can handle tough grass and the occasional hidden branch or rock. Users note they feel substantial and well-made for the price. Installation is straightforward, though a few people on dual-blade decks had to grind a small amount of material for proper clearance. That's not uncommon with aftermarket blades, and once fitted, they work fine.

One thing to watch is the mounting pattern. John Deere 42-inch decks use two different blade types: a 7-star pattern (these blades) and a circular pattern. If you have the circular pattern, you need a different part (M145476 GY20568). So double-check your original blade before ordering. Also, the blades come with a protective coating that some might think needs to be removed, but it wears off naturally after a few minutes of mowing. No need to sand or scrape it off.

Overall, the Grasscool GY20850 blades are a smart buy for homeowners and DIYers who want reliable mulching performance without paying OEM prices. They cut well, last through a season of regular mowing, and fit most popular John Deere models. Just confirm your deck uses the 7-star pattern and you will be set. If you need a set that balances cost and quality, these are worth considering.

These KOFINAM mulching blades are designed as a direct replacement for John Deere 42-inch deck mowers. They match the dimensions and mounting pattern of OEM parts like GY20850, GX22151, AM137328, and AM141033, making them a straightforward swap for worn or damaged blades. The package includes two blades, which is exactly what you need for a twin-spindle deck, so you can replace both at once and keep your cut even.

Who should consider these blades? They are best suited for DIY homeowners who maintain their own lawns and want a cost-effective way to keep their mower performing well. If you own a John Deere LA100, LA105, LA110, LA115, LA120, or any of the other listed models, these blades will bolt right on. They are not intended for commercial or heavy-duty use, but for weekly residential mowing they get the job done without breaking the budget.

Real-world performance is solid for standard turf grasses. The mulching design uses a curved shape and sharpened edge to lift grass and cut it multiple times before dropping it back. On typical lawns with Bermuda, fescue, or bluegrass, you can expect a clean finish with minimal clumping. The blades are made from 0.157-inch thick steel, which is adequate for occasional light debris like twigs or leaves, but you should avoid hitting rocks or large branches to prevent bending.

Build quality is decent for the price point. The steel feels sturdy, and the 7-point star center hole fits snugly on the spindle, reducing vibration. However, like many aftermarket blades, they may not be perfectly balanced out of the box. It is a good idea to check balance with a simple balancer before installation to avoid excessive vibration that can stress the spindle bearings. There is no anti-rust coating, so storing the mower in a dry place will extend blade life.

Overall, these KOFINAM blades offer a practical, budget-friendly solution for John Deere owners who want to restore mulching performance without paying OEM prices. They are easy to install, widely compatible, and backed by a six-month warranty. If you are a DIY homeowner who mows a typical yard and wants decent results at a low cost, this two-pack is a sensible buy. Just remember to balance them before use and avoid rough terrain to get the most out of them.
