Best Mulching Blade Buying Guide

What Are The Types Of Lawnmower Blades?

Regular blades

Regular blades (2-in-1 blades): used to cut grass and bag or discharge the clippings. A standard blade is aerodynamic and straight to deliver a powerful lift expelling grass clippings from under the deck.

The standard mower blades are ideal when mulching grass clippings might not be possible. Many like to bag the grass clipping for a more beautiful-looking lawn.

Bagging clippings can remove debris and leaves from your lawn to leave a well-manicured cutting.

It is advisable not to use regular blades for overgrown grass to clog under the deck and leave grass clumps on the freshly cut lawn.

Mulching blades

Mulching blades (3-in-1 blades): used to mulch or bag grass clipping. They come with more curves and a better cutting edge.

They can be used as a natural fertilizer to nourish the soil and plants.

How To Choose The Best Mulching Blade

Length

It is best to choose the mulching blade with the proper length. The lawnmower and all components are specifically designed for a specific blade length.

Setting up a too-small mulching blade can offer less than optimal results in 3 different methods.

  • You make more passes as the area the mower covers is smaller.
  • You can miss small grass strips altogether for mower decks with multi-blades, leaving the grass look like a mosh pit with various Mohawk cuts.
  • The bagger is probably ineffective because of lacking airflow. Most mowers display the cut size on the mower side (22 inches, 48 inches, and more). That’s why it is best to check the machine to find the right length.

Weight

Mulching models are significantly heavier than regular mower blades. Purchasing a heavy blade can make the tool break down or malfunction.

As the mower might not be prepared for heavy blades, buying a blade without considering its weight might not be a good decision.

Structure

The structure is another element that can decide if your blade can work or not. So it is advisable not to sleep on this factor. Mulching blades have varying shapes or structures.

After you seek an option catching your eyes, going through the blade details and which brands it’s compatible with.

Durability

You will not want to buy a blade that cannot last long. Remember to check the material of the blade in question. Heat-treated industrial steel is the best idea for lawnmowers blades.

Besides, you had better check its corrosion resistance. As you can mow the lawn in the morning when it’s full of dew, the mower can get wet. It is best to choose the one unaffected by water to avoid rusty blades.
