Are you tired of using rake, lawn waste bags, and green waste pickups? The mulching blade brings the solution to this problem.

Moreover, mulching blades add extra fine cutting features if you install them right and they are way much advanced than regular blades.

Best 21-Inch mulching blade | Maxpower 331981B Gold Metal Blade

If you are finding it hard to match the right size of the blade that has the right fitting for your 21-inch deck lawn mower, then this universal blade is the right choice.

With sharp teeth, straight profile, cutting quality, durability, and its universality, this blade happened to be the right choice for me.

Coupled with a 21-inch size, this blade works on a lawn that is damped and holds water.

It cuts damped dew-covered grass into the short clippings right away. You can use these short clippings to mulch-Hence reducing the effort to throw away clippings or baggings.

Before running the mulching mower, please ensure the grass is not wet (due to watering the lawn).

Not to mention, being manufactured by the brand “Maxpower” in the USA, these blades show enormous compatibility with all 21-inch deck mowers like Troybilt, Husqvarna, Craftsman, MTD, Snapper, and John Deer.

It comes with a 1-inch circular hole with reducing washers to make it easy to mount it on the crankshaft/blade adaptor of your mower.

I have seen few landscapers mounting it the wrong way and complaining about “it is not cutting right”. To avoid such things, use the reducing washers and fit them while teethes should face the deck.

In my opinion, make sure you fit it the right, so it doesn’t wobble; it will cut grass, leaves, and weeds into fine mulch right to fertilize your lawn.

Thumbs Up
  • Universally fits all 21-inch deck lawn mowers
  • Straight profile, unlike other blades that has a bump in their structure
  • Sharpened cutting teethes to produce a fine cut, enhance efficiency if sharpened more

Additionally, these blades have perfect and sharp fins to produce fine mulch. Also, it avoids clogging and lessens the cleaning operations.

One noticeable feature is that it has some thickness (187-inch) which makes it a little heavier.

You don’t need to remove the paint on it to make it sharper as it already serves the purpose when it comes packed.

Buying Guide

Compatibility Fitmen / Mounting Options

Compatibility is by far the most important factor which depends on different parts of blades.

Here are the enlisted factors and measures that come under the umbrella of compatibility, so have this checklist noted before making a final decision.

Check Hole Design & Size

Mulching blades holes are of different sizes and designs, including universal, five-point, six-point, 7 points, and circular.

So, before you make a final decision, look at the spindle substrate of your lawnmower, where you will mount the mulching blade.

Length and Mower Deck Size

Length is another important factor that decides the airflow and cut quality. So, blades of a certain length must match the deck size of the mower.

A smaller blade will create less airflow and mulches less. Also, it will increase your mowing passes because of uncut grass stipes left behind.

Larger blades will slow down the mower’s shaft and result in clumping due to low speed. Also, these can damage other blades on deck or the engine itself.

It would be best if you looked at the side of the mower to check cut size or length, or you can use your mower’s manual to find a good fit.

Mulching blade length usually varies from 16 to 54 inches.

Weight

Mulching blades are heavier due to the material they are made of.

These require some more RPM (rotation per minute) to operate on your mower.

The weight can slow down the mower, so if you buy a thicker blade, make sure to check the condition of your engine as the old mower might now support its rotation and results in clogging. 2-4 pounds or near to that range is normal for mulching blades.

Anyhow, to avoid weight resistance, you need to make sure to turn on your mower and warm it up in a resting position so it will work smoothly when you engage the cutting deck.

Using blades of different materials is also bad as it will cause turbulence in the mower, which will hurt the shaft itself, or it may totally seal the engine.                        

Material

The material from which the blades are made gives you the idea of the longevity of blades. High carbon steel works well in this case without bending and is quite handy over many seasons.

Thickness

Thickness also affects the life of blades and matters when you accidentally hit an obstacle as it prevents it from pending.

O.15-0.20 inches or near to that range is a considerably good thickness.

Durability

Durability is another important factor. It depends on thickness, weight, and metal material.

Thicker blades like Oregon gator blades are so far more durable as they are wide.

Sharpness

Pre-sharpened blades are always preferred as it saves time for sharpening first and fitting in your mower.

“Some buyers look at the paint and make wrong notions about sharpness.”

The best way to check sharpness is that you slightly push your thumb against the blade edge or teeth.

The Angle of Curvature

You should review the angle of the cut to ensure it truly is a universal replacement.

You make that decision based on the curve of flaps or edges.

Number of Blades Needed

The number of blades or blades kits also matters. Make sure how many blades your mower needs.

Coupled with a number, also think about weight. All blades must be identical.

Not to mention, it is a good practice if you buy an extra if your mower uses one blade alone. It will help to replace it during an emergency or accidentally hitting a rock.

Brands and Manufacturer

Brands or manufacturers also matters.

I prefer to buy USA based provider.

Noteworthy, mulching blades manufactures are Gator by Oregon, Maxpower, and Mishon Inc.

Pricing and Customer Rating

Customer rating also matters in any case to buy an item. If you have any queries, you will find the right answer in customer reviews and ratings.

Pricing of the product depends on your pocket. I would say Oregon and Maxpower win that battle every time.


Frequently Asked Questions (FAQs)

How often should I mulch my lawn?

It is better to mulch your lawn once a week during the cutting season. Too much mulching will only make a shreddy lawn where late mulching will result in tall grass and weeds unable to cut, or it will cause clumping in the mower and piles left on the property if you mow.

Will mulching blades work with a bagger?

Yes, mulching blades can work. It’s not recommended to use thick mulching blades with a bagger mower because it reduces bag filling. The main reason is that thicker blades are made for heavy engines; they do not create enough airflow to lift the grass on old or traditional ones. In short, mulching blades will work for bagging leaves and grass if you have a good working mower.

When to use mulching blades?

You can use mulching blades once a week. The best time to use is when your grass is 2:00-4:00 pm because, at that time, the grass is not wet. Also, when your grass grows 3 inch high, you should mow it otherwise tall grass cause clumping in the deck if cut late.

Can you sharpen a lawnmower blade without removing it?

The hard answer is yes; to do so, you will have to hold the blades real tight and use the 10-inch file with a handle to rub against the blades. You can also use other sharpening tools made for blades. Always use metal gloves to avoid injury. On final thoughts, it is not recommended to sharpen a blade without removing it as it is an uphill task. So, remove your blade and sharpen it only if you are a professional.

Can I use mulching blades with side discharge?

Yes, you can use it as side discharge throws grass clipping on the topsoil effectively, and it also avoids grass clumping in the deck of your mower, which is a plus. You will need to buy a blade that has a good lift.

Can you put a mulching blade on any mower?

No, you can only use the mulching blade on a mower if is a mulcher type or it has a shaft on which you can install a mulching kit. A mulching kit is used to fit a mulching blade on non-mulching mowers.

Can you use mulching blades without a mulching kit?

Yes, if blades fit your mower properly, you can skip the use of mulching kits as mulching kits are used to convert your mowing deck into a mulching deck using fitting hardware that comes with the kit.

Is it safe to leave grass clipping on the lawn surface?

Yes, once you leave grass clippings on topsoil, these act as fertilizer when decomposed, nourishing the lands, which is a positive point regarding mulching. Additionally, mulch has NPK(nitrogen, phosphorous, potassium) elements in it to make your soil nutrient-rich.

How can I know my mulching blade cut better?

The cutting power of the mulching blade depends upon the angle of curvature and sharpness of edges. If these two factors are good, then they will surely cut better. They will not leave any grass stripes or clumping.

Where to buy mulching blades?

The most trustworthy brands to buy mulching blades are Gator, Maxpower, and 8Ten. You can explore these brands on Amazon to find the best match for your lawnmower.

In the final analysis, mulching blades do take the hard work off and bring you a good sight of your lawn by adding mulch to your lawn which is nutritive and act as fertilizer—here the right choice of mulching blades matters which depends on their compatibility with your lawn mower.
