Mulching blades are needed when talking about keeping your lawn clean and nice looking. Nowadays, the market is full of offers, but it can be a big adventure to find the best mulching blades. I believe that my article will be useful and help you find the best lawn mower mulching blades for everyday use.
With the mulching mower blades, the grass is cut into many small pieces, so the decomposing process takes less time. Moreover, there is no need to gather the grass in one pile, it’s enough to leave it the way it was cut to decompose, so, it saves you much time.
It should be noted that mulching blades differ from standard ones because they are capable of doing three types of work at once: mulching, discharging, and bagging. That’s why sometimes they are called “3 in 1” or “all-purpose” models.
I suggest you look at the list of the most popular mulching blades presented on the market, check out pros and cons of each model, and find the best one for yourself.

Lawn Mower Blades: Classification
There are many types of lawn mower blades on the market. They are of different dimensions and designs providing a big choice of cutting and mulching options.
Standard/discharging blades are commonly used in most lawn mowers. Usually, they are curved-up to provide constant airflow while blade rotating. Such a design allows cutting the grass efficiently. This type can also be called lifting blades.
Lifting ones are subdivided into high-lift, medium-lift, and low-lift ones. In practice, the high-lifting blades require more horsepower to rotate and the low-lifting blades need less HP correspondingly. Usually, your choice depends on grass height and density. If your lawn is well-cleaned and needs mulching, low-lifting blades will be enough to succeed.
Mulching ones are often called “all-purpose” or “3 in 1” blades because they do three actions at once. First of all, they cut the grass on the lawn, then they suck it into the deck, chopping on small pieces and pushing small clippings back on the lawn to enrich your soil. Due to multitasking, the mulching blades have a more curved surface and extra cutting along the blade edges.
How to Sharpen Mulching Blades
Please note that even dull pieces can be quite sharp, so don’t neglect using working gloves while sharpening mulching blades.
First of all, you need to remove the spark plug wire when you start working with the blades. It helps prevent it from accidental working and save your hand from unexpected injuries.
The blades usually have a bolt or nut holding them. Don’t try to loosen it with your hand or feet, it’s better to use a breaker bar or long-handled wrench that will fit your blade. It is quite handy to paint or mark one edge so it will be simple to identify the bottom from the top when you reinstall the blade.
The sharpening process doesn’t take much time because blades are usually made of soft steel, so 50 strokes will be more than enough. Use a narrower file to sharpen the curved edges and a wider file for the rest blade surface. Don’t make them very sharp. In this case, they will become dull much quicker. The “Butter knife” sharpness will be enough for lawn mulching.
It is important to balance the blade before reinstalling it as the unbalanced blade can cause big damage to the shaft and bearings. Reinstall the blade and tighten the bolt/nut with a breaker bar or long-handled wrench. Your blades are ready to use!
How do Mulching Blades Work?
The mulching blades are designed to chop the leaves on small pieces and blowing them out of the mower machine to nourish the soil. These blades differ from regular ones as they have extra teeth to destroy the leaves on every rotation. However, the mulching blades are not as good at mowing as regular ones. So, for a nice-looking lawn, it is recommended to use two sets: one for mowing and another one for mulching.
Before using the mulching blades for leaves destroying, it’s better to mow your grass with regular ones to cut the tallest areas and make the mulching process more productive. Then install the deck a little bit higher than it usually works. Run over the leaves and repeat this action until no leaf is left.
How to Install Mulching Blades
The mulching blades are commonly used in lawn mowers, so let’s figure out how to install mulching blades for the most efficient functioning.
First of all, you need to disconnect the spark plug wire from the spark plug before mulching blades installation. Then turn the mower on its side so that the carburetor is on the high side. This position will prevent oil leaking.
Look at the mulching blades and find the “Bottom” part. That will be the side that faces the ground when the mower is upright. Place the mulching blades over the blade spindle. Put the washer over the blade and follow it with a nut. Then tighten the nut with your hand. Please note that for safety work you should use a pair of work gloves. They will protect your hand from injuries. Use a breaker bar or long-handled wrench for more solid tightening. Turn the lawn mower in its original position. Reconnect the spark plug wire.
