Best Lawn Mower Blades for Thick Grass Reviews
1. MaxPower 331740S
- Includes 1 blade for 22" Cut Poulan/Husqvarna/Craftsman
- Replaces OEM no. 420463, 421825, 437601, 532420463, 532421825, 532437601
- Measures 22" L x 2-1/2" W
This lawnmower blade fits several manufacturers with a variety of mowing machines, making it an excellent replacement for most commercial models.
It is 22 inches long, so it is suitable for lawn mowers of medium to large scale. It also has a five-point center hole, which ensures it will match without difficulty with most modern lawnmowers.
All in all, it is an incredibly durable blade made of high-quality steel manufactured right in the United States. It gives it the ultimate longevity and outstanding cutting strength once you have sharpened yourself.
The blade may not be the sharpest right out of the bag, but you can sharpen it to your specifications without too much trouble if you have a metal filer.
However, the blade does not weigh too much, so you can use it for adjustable lawn mowers that can increase the lift rate of your blades through internal mechanisms.
This versatility is perfect to trim your lawn at different times of the year while also retaining the ability to collect grass cut from the machine so that your yard is not polluted.
Another big bonus is the inexpensive asking price, which makes this a great replacement blade if your current blades start to get rusty or have recently broken.
You can easily pick up a few of these blades so that in an emergency you will always have a replacement on hand.
Ultimately, for most applications, it is a phenomenal lawnmower blade and should deliver quality efficiency irrespective of which machine you combine it with.
2. MaxPower 331737S
- 1 mulching blade for 21" cut Craftsman/Husqvarna/Poulan brands
- Replaces OEM numbers: 008020, 159267, 165833, 175052, 175064, 176135, 189028, 406706, 406712, 406712x431, 531300765, 532175052, 532159267, 532165833, 532175064, 532176135, 532189028, 532406712, 539111878, pp23020
- Blade measures 21" Long by 2-1/4" Wide
Unlike the last pick, this is the same manufacturer’s mulching blade and it is made to the same high quality that we have come to expect from MaxPower.
The blade is the perfect choice to mulch the grass you just cut and spit it out on the lawnmower’s side. It provides the soil with an effective fertilizer.
It measures 21 inches long by 2 1⁄4 inches wide and is suitable for medium-sized machines used by most owners of the residential lawnmower.
It is made in the USA and has a middle hole of 5/8 inches. When buying this mulching blade, be sure to check mount currently used by your lawnmower to make sure things match.
There is an optional list for all the blades or lawn mower models that can work with included with the purchase or on the back of the main sticker to make things better.
Besides all these upsides, it’s an incredibly affordable replacement blade that’s even better than MaxPower’s last pick we’ve been looking at.
This mulching blade, however, is a color of dark steel. While this does not affect its quality, it makes it a little harder to clean as it is more difficult to locate dirt or grassy debris on the blade, especially in low light.
Clean the blade in bright light to ensure that you check it completely for dust.
Yet ultimately, for most commercial or residential lawnmower users, we would be hard-pressed to suggest another inexpensive mulching blade.
In case of an emergency, pick up a pair to always have a replacement on hand.
3. MaxPower 331040
- Universal replacement blade
- Comes in 1-inch center hole
- Each blade includes a cover washer
Check out this universal replacement blade for those of you who have a lawnmower of a special make or model, or if you’re not sure if the other two blades we tested would fit perfectly.
It is designed to work with any lawn mowing machine capable of taking 2.25-inch long 20-inch blades.
This is achieved by including six reduction washers that can adjust the center cut hole’s fit, which is by definition 1 inch in diameter.
For many modern washing machines, this is a little tall, but it is ideal for several older models.
If the main hole does not properly suit your unit, simply fit into its surface one of the provided washers and you should be able to manage a fit.
The washers come in an inch 3/8, an inch 7/8, an inch 9/16, an inch 5/8, and an inch 13/16.
These should cover all the major mount hole sizes used in the modern era by most lawn mower manufacturers.
As a consequence, if you want to share blades with different size mowers, you can even toggle this blade between different lawn mowing machines.
The knife is a dark color and comes out of the box well sharpened, although it will never go unwarranted once you receive it.
The dark color makes it a little easier to clean the blade than with a silver blade, but ultimately it is a flexible substitute that should make finding a new blade for your niche mower a less difficult task.
As with all MaxPower’s lawn mower products, it is also quite affordable and is also made in the USA.
The one downside that we have to mention is the washer looseness; you may want to make sure that the blade is properly tightened before spinning it up.
The washers will shake or spin loose especially at the start, causing havoc at the bottom of your lawnmower.
Just make sure to secure them properly and you should have no trouble whatsoever.
4. Toro 22” Recycler
- Toro tooth mulcher blade
- Replaces 108-9764-03
- Tooth mulcher blade
This blade is a perfect replacement for mulching with two pairs of teeth on either end of its length. It is 22 inches long and is ideal for lawn mowers of medium to large size.
The teeth make it an outstanding mulching tool that can make even thicker or harder weeds work for the rest of your yard and make them a superb fertilizer.
The blade is made of strong and durable steel and has a dark paint finish that prevents as easily as unpainted blades from corroding or accumulating damage.
This makes it a bit harder to clean, but all in all, it’s a pretty long-lasting blade and it’s a great choice if you don’t like very often buying new replacements.
This blade has three mounting holes for you to choose from, so it will work without too much trouble on most modern lawnmowers.
Its height can also be adjusted if you have the right mower model, so the performance you get from this blade can be further customized.
As far as sharpness is concerned, it does a good job of cutting through thicker or tougher turf, but with your own metal file, it should be constantly sharpened as the edges wear down quite quickly.
This is a little drawback as blade sharpening repair does not usually have to occur very often.
But we’re willing to pass it as this blade is ideally used to mulch thicker grass that still puts up more of a fight.
It’s cheap and with your order, you get free shipping, so if you want anything heavy-duty that can shape your yard without much trouble, pick up this mulching blade.
5. EGO Power+ AB2101 21-Inch
- Enhance the bagging efficiency of your 21" EGO POWER+ Lawn Mower
- Specifically designed for use while bagging clippings with EGO POWER+ 21" Lawnmowers
- Not recommended for use with the mulching plug
This 21-inch lawnmower blade is a variant of high lift designed for lawnmowers that handle unfavorable yards and really tall grass.
It’s a phenomenal option to pick loads of grass in heavy-duty bags for high-powered lawn mowers or big machines.
This lawnmower blade was specifically designed for use with lawnmowers gathering their clippings in a jar.
It uses a sharpened steel blade from the factory that delivers excellent performance regardless of what type of grass or weeds you are cutting.
It needs to be sharpened from time to time, but usually, it offers an exceptionally clean cut that can result in short work of overgrowth in your yard.
That’s why we think it’s a great option for heavy-duty lawnmowers or professional mowers who often have to take their machines into wild backyards.
It also features on either of its arms a sloping arc. As a result, the lawnmower blade collects grass trimmings efficiently and reliably throws them into the bag.
Lesser quality lawn mower blades often fall grass trimmings under your lawn mower’s belly, but this blade does a phenomenal job of not giving away anything.
It features a circular mounting hole but, especially if you have some fitting washers to adjust the size of the hole, you can make it work with most modern lawnmowers.
Be sure, however, to weigh your mount before you buy. The only drawback is the relatively high demand rate, which for a single blade is a little on the expensive side.
If you want something long-lasting and heavy-duty, it’s still quite a worthwhile investment, but be mindful that this is more designed as a primary-use blade that should work long to come instead of a cheap replacement.
Take good care to get your buck’s most bang.
How to Choose a Lawn Mower Blades?
Reflect on these major factors when selecting a lawnmower blade to make sure you choose a blade that is right for your needs.
Mulching or Lifting?
Find the sort of knife you’re seeking first and foremost. Lawnmower blades move grass down, making it perfect for residential use or easily get rid of the grass.
Certain blades can mulch, but for different purposes, both are distinct and suitable.
Lifting lawn mower blades gather grass and embroider it for quick disposal in a bag at the back of your lawnmower.
Low lawn mower blades are great to trim a standard back or front yard and are suitable for smaller lawnmowers operating with less room.
They are especially good for cutting grass in residential areas rather than wild weeds.
Furthermore, low lift blades do not need much maintenance and operate well for casual use.
Low lift blades also do not take as much gasoline or energy as other blades, as they do not weigh or spin as fast as they do.
Medium raise blades are bigger and suitable for cutting thicker grass and some thinner weed types.
You can use medium-lift lawn mower blades for commercial or residential mowing jobs due to their flexibility.
This versatility makes them one of the simplest to find. You will be able to find online or in-person medium-lift lawn mower blades in most markets.
They’re also perfect if you haven’t mowed your backyard in a while, but don’t want to ruin your lawn or the surface of the yard.
High lift lawn mower blades are ideal for lots of grass second shearing.
These can clear the plenty of grass and weeds much easier than other styles of lawnmower blades and can work for longer because these appear to be constructed from more durable materials designed to withstand severe punishment.
Of course, they require more fuel or electrical power to operate on paper, but sometimes they can take less overall power because they can complete a mowing job in less time than the other two types of blades.
For commercial mowing purposes, high lift lawn mower blades are ideal.
Mulching lawn mower blades (also known as “gator” blades) are useful for composting cut grass and fine-tuning it down.
The grass is then tossed to serve as fertilizer over your yard or outdoor space. If you want to use the same ground or help it grow faster, this can be advantageous.
Of course, the size of your lawnmower blades will directly affect how well they match with your chosen lawn mower and how much grass they will cut at the same time.
With larger devices, longer blades are ideal and can easily cut yards, but they can be difficult to use in tight quarters.
With smaller lawnmowers, shorter blades are better and more maneuverable, but it takes more time to cut the same area.
All in all, trying to find replacement lawn mower blades of the same length as the blades that came with the initial purchase of your mower is a good idea.
It means that whatever they make or design, the blades should match the machine.
Finally, find the mount type that is mounted on your lawnmower.
Each lawnmower has mounted at the bottom of the machine that fits into a hole that is drilled into the middle of all lawn mower blades. But for different mounts, some holes are made.
There are two main types of mounts, though they are both star-shaped.
Frequently Asked Questions (FAQs)
What is a 3-in-1 lawnmower blade?
Mulching blades are often called3-in-1 lawn mower blades, due to their compact nature. The reason for this is that they can do a total of three jobs with a single blade.
They can make applications like bag clippings or discharge, chop in a fine mulch and leave them on the lawn.
How long do the blades of a lawnmower last?
It also depends on which type of mower you have. Motorized mower blades normally last for 20-25 hours until a lawnmower blade sharpener is required.
They’ll last for about 150-200 hours of mowing about the average lifespan. Okay, the Premium quality blades will last as long as 400 hours.
Why is my lawnmower blades miss the grass?
The most common reason your grass blades lack due to the dull blades.
There are however several other reasons for the cause that are not as common as the dull blades.
Tall/wet grass, damaged leaves, poor engine performance, low throttle, low floor, high lawn speed, full grass pocket, and clutch slip may also be the other factors.
How to change a lawnmower blade?
If even when you’ve just mowed it, your lawn looks ragged then it’s time to replace your lawnmower blade.
Lawnmower blades blunt with use, and if left too long without sharpening they may become so blunted and damaged that they need to be completely replaced.
It can be a bit fiddly to replace your mower blades, but if you follow our guide you can replace your mower blade with relative ease and confidence at home.
First, tilt your mower towards the underside for easy access.
It is important to do this in such a direction as to avoid spilling oil everywhere; the safest option is usually to tap it back towards the handle.
You will ensure that it is carefully and stably assisted to ensure that during the blade replacement process it does not tip over!
For safety, unplug the spark plug, to avoid accidental fires or other damage. Unbolt the blade mounting bolt using a socket wrench while using your other hand to keep the blade still for safety.
Turn the bolt counterclockwise to do this, and then remove the blade carefully, making sure the blade assembly does not lose any washers or other small components.
Then install your lawnmower spare blades in the same direction as the old one. Do this carefully while wearing protective gloves, since it’s going to be far sharper than the old blade you just removed.
Always tighten the nut, but do so carefully to avoid over-tightening, which can bend the blade and potentially cause considerable problems.
You can replace the spark plug once you have done this, turn your mower back to its normal orientation and you will be ready to start mowing again.
How to sharpen a lawnmower blade?
If your mower blade is used frequently it can become blunt.
Nonetheless, before it becomes blunt and badly damaged to require full replacement it will become slightly blunt, significantly reducing performance and cutting quality.
When that happens, you can save a blunted blade by removing it from your mower, and carefully sharpening it.
First, tip your lawnmower over and make sure it’s secure and stable. Tip it backward instead of sideways to lower the chance of oil spillage and later problems.
Then remove the spark plug as you replace the lawnmower blade, to prevent sparking and injury.
Using a socket wrench, undo the blade fastenings and remove it carefully, making sure that you take note of how the blade rests in its housing to ensure that you do not upside down replace it!
While doing this, use your other hand to hold the blade carefully in place, preventing it from swinging freely while you are disconnecting the housing.
Clamp it in a vise or tight clamp to sharpen the blade, ensuring it is kept firmly in place, with no space to wiggle.
To simplify the cleanup process, place some newspaper beneath it to catch escaped metal filings in the process!
Then take a big metal file, and run it along the blade’s cutting edge. Pass your file from the inside to the outside of the blade until visibly shiny and clean is the cutting edge, then turn the blade over and repeat the process on the other edge.
Follow the blade angle as you do so to ensure the cutting edge remains smooth and regular. Once it’s all sharpened, reinstall the blade and replace the housing.
Again tighten the nut until closely fitted with no room to shake the blade. Nevertheless, do not over tighten the nut, as this can cause mower blade warping and later major problems!
How to clean a lawnmower blade?
Regularly cleaning a lawnmower blade can help keep your lawnmower running at peak efficiency for as long as possible, as well as reducing the need for regular, intensive maintenance and helping your mower blades last as long as possible.
A clean blade can help keep your grass healthy and grow well too! Tip your lawnmower first.
Tilt it sideways rather than sideways to avoid oil spillage, and make sure it is held securely in place to keep the mower from dropping during maintenance.
Then, the spark plug is removed. This is to reduce the risk of sparking and injury while cleaning your lawnmower blade, for your own safety.
Spray the blade and its housing with a hose to remove all the residue of crusted grass and, as far as possible, simplify the manual cleaning process.
The higher your hose can muster the pressure, the easier it will be to blast the majority of the debris from your mower blade and blade mower housing.
Brush off any stubborn residue with a hard wire brush, then get ready to remove the blade from its casing.
To remove the nut, use a socket wrench, and carefully lift the blade out of the mower housing.
Wipe the blade down on both sides and cover it with a thin layer of vegetable oil to prevent future use of further debris.
Then replace the blade, tighten the nut again (be careful not to tighten too much), replace the spark plug and you are ready to mow again.
With the best lawn mower blades for thick grass reviewed above, the MaxPower 331740S Mower Blade is a great choice for most modern lawnmowers in terms of all-around useful blades and should work for both residential and light commercial needs.
