Craftsman Mower Blade on Sale of 2026 For Cleaner Cuts

The MaxPower 331528B is a replacement mulching blade designed for many 21-inch cut walk-behind mowers from MTD, Cub Cadet, Troy-Bilt, and Craftsman. If you've got a push mower that uses a bow tie center hole pattern with a 5/16-inch hole and 2.5-inch spacing, this blade is likely a direct drop-in. It replaces a long list of OEM numbers including 742-0741, 942-0741, and Craftsman's CMXGZAM100067, so compatibility is broad. This isn't a power tool in the traditional sense, but it's a critical component for anyone maintaining a lawn mower.

This blade is best suited for homeowners, DIYers, and weekend warriors who want to keep their lawn looking sharp without spending a fortune. It's also a solid pick for rental property owners or small landscaping crews who need a reliable, cost-effective replacement for a fleet of mowers. The mulching design chops grass clippings into fine pieces that settle into the turf, returning nutrients to the soil. That means less bagging and a healthier lawn overall.

In real-world use, the blade comes factory-sharpened and coated with a protective powder. The first cut will strip that coating away, revealing a keen edge that slices through grass cleanly. Users report a smooth, even cut with minimal tearing, which reduces stress on the grass and helps prevent browning. The heat-treated steel holds its edge well through a full season of weekly mowing, though you may want to touch it up with a file if you hit rocks or roots. Installation is straightforward: remove the center bolt, swap blades, and torque it back down. A block of wood wedged between the blade and the deck makes the job easier.

Build quality is solid for an aftermarket blade. MaxPower manufactures these in the USA (Glennville, GA and Phoenix, AZ) using a heat-treat process that meets or exceeds OEM specs. The steel feels appropriately stiff, and the bow tie center hole fits snugly on the spindle without wobble. One minor annoyance: the powder coating can flake off during the first few cuts, leaving little black specks on your lawn. That's cosmetic and harmless, but worth noting. Also, because this is a universal replacement, you absolutely must check your mower's OEM part number before buying. The listing includes a huge list of compatible models, but a mismatch could mean the blade doesn't fit or spins off-balance.

Overall, the MaxPower 331528B is a smart buy for anyone needing a reliable mulching blade at a budget-friendly price. It cuts well, fits a wide range of mowers, and is built to last. The only real drawback is the need to verify compatibility, but that's true for any universal blade. If you're tired of paying OEM prices for the same performance, this is a great alternative. Just double-check your part number, and you'll be back to mowing in no time.

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.

Compatible models include Craftsman LT1000, LT2000, Husqvarna YTH series (2009 and newer), RZ series zero-turns, Poulan PB19H42YT, PB20H42YT, and many others. Always verify your original blade's mounting pattern before ordering. If your blade has a 6-point star hole, use OEM numbers 942-0616A or 942-04308 instead.

The UDC Parts 138971 (also labeled 532138971) is a 42-inch high-lift mower blade designed to replace OEM parts on a huge range of riding mowers from Craftsman, Husqvarna, Poulan, AYP, and others. This two-pack provides both blades needed for a full deck, making it a convenient and cost-effective alternative to buying from the local hardware store.

Who should buy these blades? They are ideal for homeowners and DIYers who want to improve the cut quality of their 42-inch riding mower without paying OEM prices. Contractors and property maintenance crews will also appreciate the consistent performance and durability across multiple mowing cycles. The high-lift design is especially beneficial for those who mulch or bag grass, as it produces a fine, evenly distributed clippings that disappear into the lawn, eliminating the need for raking or re-mowing.

Real-world performance is outstanding. Users report a dramatic reduction in noise, with the blades producing a soft hum rather than a loud roar. The cut is clean and even, even in slightly overgrown grass. The high-lift action creates a vacuum effect that lifts grass before cutting, resulting in a manicured look. Several reviews mention being able to drop the deck height one notch and still get a great cut. Durability has been solid after several months of use; the blades hold their edge and show no signs of bending or chipping.

Installation is straightforward. The blades feature a standard five-point star center hole and match the OEM dimensions exactly: 21 inches long, 2-1/4 inches wide, and 0.157 inches thick. They bolt directly onto the spindle without any need for adapters. Balance is good, and vibration is minimal, which reduces wear on spindle bearings and improves operator comfort.

Drawbacks are few but worth noting. The strong suction can pull in small debris like stones or hoses, so you must keep the area clear. Also, because the blades are slightly heavier than some stock ones, they might cause a minor imbalance on older, worn-out decks. Double-checking compatibility using the full model number of your mower is essential, as some models with similar names may use different blades. Overall, these blades deliver exceptional value and performance. If you want a quieter, cleaner cut from your 42-inch rider, this two-pack is a no-brainer.

If you own a 42-inch deck riding mower from Craftsman, Husqvarna, or Poulan Pro and need fresh blades, the Grasscool 138971 replacement set is worth a close look. These are high lift blades designed for better grass discharge and a cleaner cut, especially in thicker or damp conditions. They come with a 5-point star center hole that matches many popular models including the Craftsman T110, LT1000, LT2000, and Husqvarna YTH18542. Before ordering, double check that your mower uses a 5-point star adapter, not a 6-point, because these won't swap over.

Performance wise, these blades do exactly what you'd expect. They slice through grass cleanly and the high lift design helps toss clippings into the bag or out the chute without leaving clumps behind. Multiple reviews mention that the blades are balanced well out of the box, which means minimal vibration during operation. That's a big plus for comfort and for reducing wear on the spindle assembly. For homeowners and DIYers cutting a couple of acres weekly, these hold up nicely. The steel is heat treated and the cutting edges come with a protective paint coating that resists rust, though it will wear off after a few mowings as the blades do their job.

Build quality is solid at this price point. Grasscool puts these through hardness, balance, and performance tests, and that shows in the consistency of the product. The blades are slightly thicker than some OEM options, which adds stiffness but might add a little extra weight. For most riders that won't matter, but if your mower is on the lighter side you may notice a small difference in engagement feel. Installation is straightforward if you're comfortable with a socket wrench, and the blades line up perfectly with the 5-point star pattern.

One realistic limitation is the star point compatibility. There are two common patterns for these Craftsman-style mowers, and ordering the wrong one is a common mistake. Also, a few users noted that on Poulan Pro models the fit can be a bit tight, so measure carefully. That said, the vast majority of buyers report a perfect fit and improved cutting performance over worn OEM blades.

Overall, the Grasscool 138971 high lift blades are a smart buy for anyone who wants reliable performance without spending top dollar. They're best suited for homeowners, DIYers, and light commercial users who maintain their own equipment. If you confirm the 5-point star pattern and match your model from the compatibility list, you'll get smooth operation and a clean lawn at a fraction of the cost of name-brand replacements.

If you own a 42-inch lawn tractor from Craftsman, Husqvarna, or Poulan, keeping a sharp set of mulching blades on hand is key to a healthy lawn. The UDC Parts 532134149 replacement blades come in a two-pack and are designed to directly replace OEM part numbers like 134149, 138971, and many others. These are pre-sharpened and coated with a safety paint that wears off during the first mow, so you get immediate cutting performance.

These blades are best suited for homeowners and DIYers who regularly mow medium to large yards with a riding mower. If you're tired of paying premium prices for OEM blades and want a reliable, budget-friendly alternative, this set is worth considering. Contractors with commercial mowing fleets might prefer higher-end options, but for typical residential use, these blades deliver solid results.

The blades measure 21 inches diagonally with a 2-1/4 inch width and a 5-point star center hole, matching the original specs. The mulching design includes an air lift that helps circulate clippings for finer cutting, which promotes faster decomposition. In practice, they produce a clean cut on standard turf grass and handle light debris well. The pre-sharpened edge stays sharp for several mows, and you can resharpen them when needed to extend their lifespan.

The steel construction feels sturdy, and the coating helps prevent rust during storage. Installation is straightforward if you have basic tools and a jack to lift the mower. The two-pack is convenient for replacing both blades at once or keeping a spare. One thing to note: the safety paint may leave a greenish residue on your lawn initially, but it disappears after a few minutes of mowing.

The main limitation is compatibility. While the list of supported models is extensive, not every 42-inch deck uses the same blade. Always verify your mower's model number before ordering. Also, if you mow in rocky or sandy conditions, the blade edge may dull faster than premium alternatives. Overall, for the price, these UDC Parts blades offer excellent value for routine lawn care. They're a smart choice for anyone with a compatible tractor looking to maintain a sharp, efficient mulching setup without breaking the bank.
