How to Choose the Correct Mower Blade

Now that you have decided that it’s time to purchase replacement blades for your mower, where do you start? How do you choose the correct blades for your use?

There are two different mower blade types namely:

  1. Lifting Blades
  2. Mulching Blades

Lifting Blades – Also known as the standard mower blades (or sometimes referred to as 2-in1 types), these units have a slight curve along the edges. This curve is ingeniously designed to create air flow, which pulls the grass up to be chopped by the blades.

If your primary purpose is for bagging or side discharging, then this is just what you need. There are three different types available namely:

  • Low Lift
  • Medium Lift
  • High Lift

Simply put, the higher the lift, the higher the horsepower needed. If you are tackling long and thick grass, then a high lift blade would be ideal.

Mulching Blades – Also referred to as the 3-in-1 blades, they have a higher curved surface with more extended cutting surfaces along the edges. This design allows for grass to be chopped up several times resulting in smaller clippings. Small grass tends to decompose faster into the soil so if you are not interested in bagging or side discharging your grass clippings, then mulching blades are just what you need.

There are two types of mulching blades namely:

Standard mulching blades

Gator blades (they have angled teeth on each end, which guide grass to the cutting edge repeatedly)


From our research, we have selected the Oregon Gator 3-in-1 Mulching Blades to be the Editor’s choice for the Best lawn mower blades for thick grass.

Why? Simply put, this is the most versatile model available as it can be used to replace different mower blades models. Aside from this, Oregon Gator 3-in-1 Mulching Blades is affordable, durable, user-friendly, and will cut your thick grass with ease.
