Types Of Lawn Mower Blades

1. Medium-Lift Blade (Standard)

medium lift blades

Standard or medium-lift blades usually come in standard lawnmowers. You may even find them on lawnmowers that have horizontal rotation. They are also called straight blades despite having a slight curve on the end. This slight curve on the edges helps to produce airflow when the blade is rotating. This results in cutting action which helps to pull off the grass by producing suction on the land.

You should know that standard or medium-lift blades offer only minimal suction as it only lets a small amount of air pass from the blade. A buyer will have to consider the type of lawn as straight blades are perfect for dry and damp surfaces.

You can easily cut dense grasses with these types of blades. It has to be noted that these blades also come with a drawback as it is not able to cut in smaller clumps. This will lead to uneven cutting as you will have to look for other types of blades. Even minimal suction can lead to chute clogging.


  • High-efficiency performance by cutting on both damp and dry surfaces.
  • Ability to cut dense patches.
  • Better suction with slightly curved ends.
  • Ideal for all types of soil.


  • Inability to cut through small clumps can lead to an uneven lawn
  • Restricted storage in the bag.
  • Likelihood of chute clogging.

2. Low-Lift Blade

Low-Lift Blade

A low-lift blade is perfect for mowing in sandy soil as it offers low suction power. You can basically see these types of blades on side-discharging mowers. In comparison to the standard or medium-lift blades, they come with less curved edges. The low suction design of the blade will not raise the grass high. Another factor is that it will not allow the dust to rise.

These types of blades come in the size of 3 to 4 inches and require less power. When using these types of blades, your mower can last longer as it creates less strain on the engine. In a way, it is highly durable and also does not produce higher noise. It can be perfect for people who are looking to have better durability and silent operation.

3. High-Lift Blade

High-Lift Blade

What separates a high-lift blade from a low-lift blade is that it comes with vertical angles on the edges. This makes it produce high lift air with maximum vertical section. A high-lift blade comes with a quick circular motion that aids in superior performance.

It can cut with great precision and also helps in the efficient bagging process. Another great advantage of a high-lift blade is that the chances of getting trapped are very low. You can easily use them for removing compact and tall grasses as the blades come in different sizes.

However, it has to be noted that the blades can deteriorate quickly as it provides more rotation. Even the continuous spinning of the blade requires an improved horsepower engine.

Mulching Blade

A mulching blade works by mulching the grass clippings that help to provide natural nutrients to the soil. Mulching blades are suitable for discharging, bagging and creeping. It is an all-purpose blade that has a curved surface. These types of blades help to suck the clippings inside the deck by chopping them into tiny pieces.

Even it can produce air pressure that helps in better soil absorption. Despite producing less suction, it has the ability to straighten and lift the grass. Mulching blades are available in riding and pushing lawnmowers and can perform 3-in-1 functionality. The distinct cutting edge helps to cut the grass into small pieces before bagging. However, mulching blades are not suitable for cutting overgrown grass.
