Factors to Consider Before Buying Mulching Blades for Your Lawn Mower

If you are in the market for a durable and compatible mulching blade for your mowing machine, there are factors to consider. Here are some of them:

Length

Lawn mowers are designed to have a specific blade length. Installing a smaller mulching blade may not allow you to achieve the excellent cutting results.

Smaller mulching blades will make you miss small strips of grass, make more passes and make the bagger look ineffective due to lack of airflow. 

Lawn mower blades that are too large can also slow down your machine and cause more clumping.

Most mowers display their cut size on the side of the mower. To find the ideal length, check the model of your mower. 

If you can’t find it there, check the owner’s manual under the replacement parts section.

Fitment and Mounting Options

Check the fitment and mounting options of your mower before getting a mulching blade.  Lawn mowers have different mounting holes.

Most mowers have a five-point star, bow-tie, six-point star and universal fit. 

Five-star and six-star point holes are easy to install because it requires the removal of a single bolt.

Number of Pieces

Ensure that you get a kit with the correct number of blades. For instance, most riding mowers come with two or three blades. 

For optimal performance, it is important to replace all the matching blades. Replacing a single blade might be a bad idea because of these two reasons:

  • Since mulch blades are heavier than standard mower blades, installing different weighted blades can disrupt the output of your machine because one blade might run slower than the other.
  • There won’t be better mulching and airflow because the standard blades will cause clumping.

How Do Mulching Blades Work?

These blades work by lifting the grass blades and cutting them several times. After that, the grass clippings are further shredded in the mower deck. 

The small clippings are pushed down onto the lawn. This forms an evenly distributed carpet due to the divided airflow.

Do Gator Mulching Blades Work?

Yes, they can work well if they are well-built. Gator mulching blades come with a serrated cutting edge that shreds grass into small pieces while maintaining a medium-lift.

When To Use Mulching Blades

You can use these blades when you want to mulch your lawn especially if you want to cut the grass clippings into tiny pieces that will break down when left on the ground to nourish the soil. However, there are limitations.

It is advisable to avoid mulching if you have a lot of weeds like crabgrass on your lawn. Furthermore, longer grass isn’t that mulch-friendly, especially when it is wet.

How to Get the Best Cut When Using Mulching Blades

To achieve excellent cutting results, the first thing to do is to mow the lawn more often with mulching blades than regular blades.

You should also do this when the grass is 1/3 taller than you want it to be. Lastly, choose a dry day because wet grass tends to clump.
