Factors To Consider When Buying Mulching Blades

Blade length

It is essential to have the right length of the blade for your mower. Installing too small or extra-large blades will result in poor quality cutting and mulching.

If small, you will be required to work as twice as normal to achieve the desired result. Also, for multi-blade mower decks, you will miss small grass strips, and hence the lawn will appear poorly done.

Similarly, when the blade is large, you will end up causing clumping due to slower speed and lack of space below the deck.


Consider blades that are heavier than the standard blade for mowing. This is necessary to ensure that you do not use excess energy while mowing.

Number of pieces

Purchase a kit with the correct number of blades and of the same quality. If your current mower has three blades, purchase a set of blades with three pieces for optimum performance. If you replace one, you are likely not going to see any difference. Also, get heavier blades to ensure the mower’s output is maintained.


Mulching blades are known to be durable compared to the standard ones. Ensure that the blades you purchase have a longer lifespan.

Fitting and mounting options

While some brands are better than others, consider purchasing one which perfectly fits your mower for optimum results. Similarly, the number of mounting points matters; ensure they align with the mower.

Top Tips For Finding The Right Mulching Blades

Check for the manufacturer number

The last thing you need is to order the wrong mulching blade. Thus, check for the OEM (original equipment manufacturer) number. Ensure it matches with your current blades that you wish to replace.

Model number

Check for the model name or the OEM number and a manual. Ensure it matches with your old blade.

Length and center hole

If you do not find the OEM or the manufacturer number, consider the length of the blade and the diameter of the center hole. If they match with your current blades, they are then a perfect fit for your mower.

  • · Avoid purchasing mulching blades that do not provide product specifications
  • · Buy from a trusted brand or supplier
  • · Consider the warranty length and customer feedback
