Mulching Blades For John Deere Buyer’s Guide:

Mulching blades (also known as 3-in-1 blades) are different from your regular lawn mower blades as they offer a versatile performance with their all-in-one action. We have put together a complete buying section that you can follow to get the best product for your needs.


Mulching Blades 48

The mulching blades have a rather unconventional design; these blades have a different length as compared to the regular blades. Moreover, these blades have a slightly different mechanism, as they cut the grass into fine pieces, and then throw them out in the shape of fine pieces.

Always check out the manufacturer’s instructions regarding the length of the blades as they can vary from model to model. You definitely don’t want a blade for your mower that does not fit it. Therefore, we highly emphasize checking the length of your blade before choosing a mulching blade.


The material of the munching blade plays a vital role in the functionality of the mower. A good quality mulching blade should be made out of highly durable material. In this way, it can withstand tough terrains as well.

The best mulching blades have carbon-steel construction that provides its utmost reliability. Also, it should have a construction that can handle sharpening, etc.


Since a lot of people buy new mulching blades for their existing lawnmowers. Therefore, it is highly recommended to check out the compatibility of your lawnmower with the mulching blades before settling for a particular model.


The design also plays a vital role in the working of a lawnmower. Always make sure that the blades you are choosing should have a proper design, and this design is compatible with your lawnmower.


Weight is another important aspect of choosing the right lawnmower. Since the mulching blades are much heavier than the conventional blades.

Therefore, it is highly recommended to test the weight handling capability of your lawnmower. So, it works properly with your mower.

Set Size

Last but not least, the last factor that you should be checking before making your purchase decision is the sizing of the set.

Since different lawnmowers use different numbers of blades in their construction, therefore, it is highly advisable to select the blades that have the size set that is compatible according to your needs.

Difference Between Mulching & Regular Blades

The regular blades (also called the 2-in-1 blades) are different from the mulching blades (3-in-1 blades). Mulching blades offer a more diverse cutting experience due to their curvy shape and functionalities.

Here are a few major differences between a standard lawnmower blade and a mulching blade.

ShapeFunctionalityDifference in Usage
There is a huge difference in the shape of a regular lawn blade, and a mulching blade. The 2-in-1 blade has a straight profile design. This flat design of the blade has no curves. These blades are designed in a way that they disperse the grass into the clipping bed.

While on the other hand, the mulching blades or the 3-in-1 blades have a rather radical design, these blades have an aerodynamic design with proper curves.

The standard lawnmower blades perform two functions. Firstly, they cut the grass and put it into the lawnmower deck. Afterward, they transfer this grass clipping to the bag or sometimes throw it on the lawn.

Unlike the conventional blades, the 3-in-1 blades cut the grass, put it into the mower deck, and then cut it into fine clipping, and throw it into the lawn.

Although both these types of blades are built for mowing your lawn, still, there is a huge difference in their working and functionality.

The mulching blades are best for lawns that are mowed after every few weeks. Thus, the grass is shorter, and you do not see clumps of grass on your lawn.

You can use the standard mowing blades when you do not do the frequent cutting on the lawn. These blades cut the grass from the surface of your lawn, and then dump it directly into the bagging bag.

How to Install Mulching Blades in John Deere

In this guide, we will show step-by-step how you can remove, and install new blades in your John Deere lawnmower.

  1. Firstly, you have to put your John Deere on a jack.
  2. After lifting the machine, you have to remove the nut from the center of your old blades.
  3. Also, keep the blades in place by using your other hand.
  4. Then, you have to put aside the nut.
  5. Now, place your new mulching blades into the frame.

Tight the screws, and you are good to go.

Moreover, the grass is cut into fine pieces, that act as a fertilizer, and enhance the growth of your lawn grass.

Can You Put a Mulching Blade on Any Mower?

Yes, you can use a mulching blade on any mower. However, you have to ensure that the blade you are using properly fits your mower. Additionally, you can check the length and center hole of the mower, whether it properly fits your mower or not.

Do New Mulching Blades Need to be Sharpened?

No, you do not need to sharpen up the new mulching blades. However, there are some cases in which the mulching blades have a paint coating on the edges. In these cases, it is advisable to sharpen the blades in order to get rid of the paint.

Is Mulching Better Than Side Discharge?

Well, it totally depends upon your usage.

However, using mulching blades to cut longer grass can leave clumps of grass on your lawn.

Why Does my Mulching Mower Leave Clumps of Grass?

The mulching blades are designed in a way that they cut the grass from the surface of your lawn, and after frequent cuttings, this grass is transformed into smaller pieces, and then finally thrown out of the way.

Suppose you are having problems with your mulching due to clumps of grass. It’s probably due to the usage of a longer length of the grass.

Can you use Mulching Blades Without a Mulching Kit?

How to Sharpen Mulching Blades?

You can sharpen the mulching blades just like any regular lawnmower blade. You can use a grinder to sharpen up the edges on a mulching blade for a better and faster mulching experience.

Which Way Do Mulching Blades Go on?
