Quick Review For Top 10 Lawn Mower Blades
Grasscool 942-04308 Blades with 6 Star Hole for Troy Bilt Bronco Pony Mustang 42 inch Mower Cub Cadet XT1-42 ZT1-42 42'' Zero Turn Lawn Tractor Replace 942-04308A 942-04312 High Lift
The Grasscool 942-04308 Blades are a direct replacement set for a wide range of 42-inch lawn tractors and zero-turn mowers. If your mower is from Troy-Bilt, Cub Cadet, or Craftsman, these blades are likely the correct fit, but there’s a crucial detail you must check first to avoid getting the wrong part.
These blades feature a 6-point star center hole. This is the most important thing to verify on your current blades before you order.
Some mower models, especially certain Cub Cadet and Craftsman units, can use two different blade types. If your old blade has an S-shaped hole or a 5-point star hole, these Grasscool blades will not fit. The product listing provides the alternative part numbers you’d need in those cases. Taking a moment to check this saves you the hassle of a return.
These are high-lift blades, designed for more than just a standard cut.
The high-lift design creates strong upward airflow under the mower deck. This is incredibly usefull for bagging or side-discharging clippings, especially when dealing with tall, damp, or thick grass. The improved suction helps lift grass blades for a cleaner cut and propels clippings efficiently into your bag or out the chute, which significantly lowers the risk of clogging under the deck.
Grasscool TB110 Mulching Blade for Troy Bilt 21 inch Deck Mower TB240 TB230 TB130 TB200 TB160 TB210 TB280ES TB320 TB115 TB220 21" Walk Behind Push Mower Replace 942-0741A 742-0741A
The Grasscool TB110 Mulching Blade is a direct replacement part designed for a wide range of Troy Bilt 21-inch walk-behind mowers. If your mower model is a TB110, TB240, TB230, TB130, TB200, TB160, TB210, TB280ES, TB320, TB115, or TB220, this blade is built to fit.
It also replaces several common OEM part numbers, including 942-0741A and 742-0741A, making it a straightforward swap when your original blade wears out or gets damaged.
This is a true 3-in-1 blade, meaning it handles mulching, bagging, and side-discharging all with one piece of equipment. Its design features numerous curves that are key to its mulching performance.
These curves create a strong airflow that lifts the grass for a clean cut, then cuts and re-cuts the clippings into very fine pieces. For mulching, those tiny pieces fall back onto your lawn, where they decompose quickly and return valuable nutrients to the soil, acting as a natural fertilizer.
Maxpower 331528B Mulching Blade for some 21 Inch Cut MTD/Cub Cadet/Troy-Bilt Replaces 742-0741, 942-0741, CMXGZAM100067
The Maxpower 331528B Mulching Blade is a direct replacement part designed for a wide range of 21-inch lawn mowers. If your current blade is worn, damaged, or simply not mulching effectively, this is the specific part you need for many MTD, Cub Cadet, Troy-Bilt, and Craftsman models.
Its primary job is to finely chop grass clippings and return them to your lawn as nutrient-rich mulch, which can help reduce the need for fertilizer and eliminates the task of bagging clippings.
Before ordering, the most critical step is to verify compatibility. This blade is not a universal fit for all 21-inch mowers. You must check that it matches your mower’s original equipment manufacturer (OEM) part number.
The blade replaces several common OEM numbers, including 742-0741, 942-0741, and Craftsman CMXGZAM100067. If your old blade has one of these numbers stamped on it, this Maxpower blade will be an exact fit. Always compare the old blade to the new one upon arrival to ensure the length, hole pattern, and shape are identical.
Compatibility extends to a long list of specific mower models.
Grasscool 138971 Blades with 5-Star Mounting Pattern for Craftsman 42 inch Mower LT1000 LT2000 T110 YT3000 42'' Deck Cut Zero Turn Riding Repalce 532138971
The Grasscool 138971 Blades with 5-Star Mounting Pattern are a direct replacement part for specific Craftsman, Poulan Pro, and Husqvarna riding mowers. If your mower is a Craftsman LT1000, LT2000, T110, or YT3000 with a 42-inch deck, these blades are likely what you need. They also fit models like the Poulan Pro PP19A42 and the Husqvarna YTH18542.
The key identifier is the 5-point star center hole, which is crucial for a proper fit.
Before you order, its essential to check your current blade’s center hole. Some Craftsman T110, LT1000, and LT2000 models actually use a different blade with a 6-point star hole. If your old blade has a 6-point star, these 5-point star blades will not fit, and you’ll need to search for a different part number.
This step stops the guesswork and ensures you get the right part the first time, saving you time and hassle.
These blades are built to handle demanding conditions. With specifications of 21 inches in length, 2-1/4 inches in width, and a 7/8-inch lift, they are classified as a medium-lift blade. This makes them very suitable for cutting through overgrown weeds or clearing more rugged terrain.
Honda HRX Blade Kit, (1) 72511-VH7-000 Blade & (1) 72531-VH7-000 Blade
The Honda HRX Blade Kit, consisting of (1) 72511-VH7-000 Blade and (1) 72531-VH7-000 Blade, is the official twin blade mulching set designed for your mower. If you own a compatible Honda HRS or HRR series lawn mower, this kit is the direct replacement for maintaining its original cutting and mulching performance. Its not a generic accessory; these are the blades your mower was engineered to use from the start.
This kit includes both blades needed for the twin-blade mulching system.
That system is key for how Honda mowers finely chop grass clippings. Instead of bagging or discharging, the blades cut and recut clippings into tiny pieces that fall back onto your lawn. This acts as a natural fertilizer, returning nutrients to the soil and helping to retain moisture. It saves you the work of bagging and means you dont have to buy as much extra fertilizer.
The mulching process relies on the specific design and balance of these genuine Honda blades to work correctly.
Each blade in this kit is a genuine OEM Honda part. That means its manufactured to Honda’s exact specifications for material, weight, and cutting geometry. Using original blades ensures a perfect fit and optimal balance on your mower’s spindle. Proper balance is crucial—it reduces vibration, which protects your mower’s engine and deck from unecessary wear.

The Grasscool ZT1 50 Blades with 6 Star Shaped Hole are a direct replacement part designed for a wide range of Cub Cadet and other brand mowers. If your mower uses the specific 6-star shaped center hole, these blades are built to match the original specifications for a precise fit and performance.
Before you order, its crucial to check your current blade’s center hole shape. This model uses two different types. These Grasscool blades feature a 6-point star shaped hole (5/8″).
If your existing blade has an S-shaped center hole, this is not the correct part for you, and you should look for MPN 742-05094 instead. Getting this right the first time saves you the hassle of returns and ensures your mower operates safely and efficiently.
These high-lift blades are engineered to create strong upward airflow.
This design is ideal if you use a grass collection system or prefer bagging your clippings, as it helps lift the grass for a cleaner cut and improved bagging performance. The blade specifications are: length 17-1/4″, width 2-3/8″, thickness 5/32″, with a cutting edge length of 5-1/8″. They are compatible with both 34-inch and 50-inch cutting decks.
Compatibility is a key strength of this blade. It directly replaces Cub Cadet/MTD numbers 742-05052A, 942-05052A, 742-05052, and 942-05052.

The Grasscool 942-0741A Mulching Blade is a direct replacement part designed specifically for a wide range of Troy-Bilt 21-inch walk-behind mowers.

Its dimensions are a standard 21 inches in length, 2-1/4 inches wide, and it’s built for a 21-inch mower deck.

Lawn Mower Blades Buying Guide
Selecting teh correct blade is essential for a clean cut and a healthy lawn. The right lawn mower blades make all the difference, turning a ragged chore into a smooth, efficient job. This guide will help you pick the perfect blade for your mower and grass type.
Blade Material and Build
Not all blades are created equal. Most are made from hardened steel, which offers a great balance of durability and affordability. For tougher conditions or longer life, look for blades made from higher-carbon steel or those with reinforced tips. A flimsy blade will dull quickly and bend on impact, leaving you with an uneven cut.
Blade Shape and Design
This is where function really varies. Standard straight blades are great for basic mulching and bagging. High-lift blades create a strong upward suction, ideal for bagging and achieving a clean, striped lawn. Mulching blades, with their curved design and extra cutting edges, finely chop clippings and return them to the turf as nutrients. Consider what you do most often.
Compatibility is Key
This is the most critical step. Blades are not universal. You must match the blade’s center hole shape and size, length, and thickness to your specific mower model. Using an incompatible blade is dangerous and can damage your machine. Always check your owner’s manual or the old blade’s part number before you buy. Don’t just guess!
Sharpness and Maintenance
A sharp blade tears grass; a dull one shreds it, leaving brown tips and opening the door for disease. Inspect your blades regularly for nicks and wear. You can sharpen them yourself with a file or grinder, but ensure you balance it afterward—an unbalanced blade causes damaging vibration. Many find it easier and safer to simply replace worn blades annually.
Frequently Asked Questions About Lawn Mower Blades
How do I know which blade fits my mower?
The safest way is to check your owner’s manual. You can also take your old blade to teh store to match it. Note the model number of your mower, as blades are not universal. Getting the right size and center hole shape is crucial for safety and performance.
How often should I sharpen or replace my blade?
You should check your blade’s sharpness every 20-25 hours of mowing. A dull blade tears grass, leaving a brown, ragged tip. Sharpen it or replace it when you see this. Most blades can be sharpened a few times before needing replacement due to wear.
What’s the difference between standard and mulching blades?
Standard blades are designed to discharge grass clippings out the side. Mulching blades have a special curved shape to keep clippings under the deck longer, chopping them into fine pieces that decompose into the lawn. You need the right blade for your mower’s function.
Can I install a new blade myself?
Yes, but safety is key. Always disconnect the spark plug wire first to prevent accidental starting. Tip the mower with the air filter side up to avoid oil leaks. Use a block of wood to lock the blade in place while you loosen the bolt. Remember, the cutting edge should face the grass.
Why does my mower vibrate more with a new blade?
Excessive vibration often means the blade isn’t balanced. Even a new blade can sometimes be off. You can check balance with a simple blade balancer tool. An unbalanced blade puts stress on your mower’s spindle and engine, so it’s important to get this right.
Are more expensive blades worth it?
It depends on your lawn. For basic, flat lawns, a standard blade is often fine. If you have tough conditions or want a better mulch, a higher-end blade with special coatings or alloys can last longer and perform better. They hold a sharp edge for more mows, usually.
Final Thoughts
For a truly clean cut, teh right blade is essential. Consider these top options to finish your lawn perfectly. Think about your grass type and how often you mow. A sharp, correct blade saves you time and gives your lawn that crisp, healthy look. It’s a simple upgrade with a big impact.
Remember, even the best mower needs the right partner. Dull or bent lawn mower blades tear grass, leaving it vulnerable to disease. Check yours regularly for wear. A quick swap at the start of the season makes all the difference, ensuring your yard stays green and thick all summer long.
