That’s why we have made the following guide to help you through this process: 

Blade Length

The length of the blade should be your first concern while buying a replacement blade. You have to check the deck size of your mower and buy the blade that will fit your mower’s deck perfectly. 

Type of the blade

There are two major types of lawnmower blades made by Greenworks. The first one is the mulching blades. These blades are curved, and they produce finer clippings. 

On the other hand, there are also discharging blades. They can cut the grass and shoot the clippings out of the deck pretty quickly. 


The blade has to be compatible with your Greenworks mower. That’s why you should check whether your mower’s model number is included in the product description. 


Almost all of the blades that we have listed are made of steel, and they come pre-sharpened. The blade needs to be sharp to provide better cutting performance.
