How to Find the Right Mulching Blades for John Deere?

Read the product description to figure out if it can replace the blade of the specific model. Valuable information is also usually given in the user manual, you can also take help from it to find the best blades.


Do not overlook the material of the blade, Opt for blades made of hardened steel or carbon steel. The hardened steel does not bend easily and offers excellent cutting performance and longevity.


Surprisingly, mulching blades come in various shapes and designs. However, the market is bombarded with straight blades with serrated teeth. So, you might have to choose between these two types. The toothed blades are preferred by the experts because they create finer mulch.

Length, thickness, width, and weight

The length, thickness, width, and weight of the mulching blades tell a lot about it. 

  • Length – You can tell if the mulching blade would fit your mower or not by judging it by its length. The mulching blade should be of the same length as the lawn mower’s deck. Otherwise, it would not fit. So, if your mower’s deck is 42″ inches, you have to place an order for a blade that is 42″ long as well.
  • Thickness – Whether you are purchasing for John Deere or any other lawn mower, the mulching blades must be thick enough. If the blades do not have a decent thickness, they will bend and you have to get a replacement.
  • Width – Mulching blades must have a decent width. The decently wide mulching blades can cut and mulch more grass in a single pass. They save you time, and effort, and give a more even and consistent cut. So, whenever you have to choose between mulching blades, opt for the one with a decent width.
  • Weight – It’s important to know that the mulching blades should not be too heavy. The heavier blades require more power to perform the job. So, try finding a blade that either or under 2 pounds.

Fitment hole

You have to pay attention to the tiniest details such as the fitment hole to ensure the perfect fit. The center hole can be round, have 5 or 6 points, or have a bow-tie shape. Find the suitable shape to adjust the blade on the mower without any hassle.

Number of blades

The mulching blades usually come in a set of two or three. You need to know how many blades are required for the job so you can buy accordingly.


Lastly, you have to check the price of the mulching blade. You can buy a decent mulching blade for under $50. Most of the above-mentioned mulching blades are under $50. So, if you are planning to purchase affordable but quality blades, you can consider these options.
