Greenworks Blade Assembly Kit

This kit is designed for select 21-inch Greenworks walk-behind mowers. Because compatibility can vary by specific model number, we recommend checking your mower's manual or the product compatibility list to ensure this assembly matches your unit before purchasing.

The fan is a critical component for airflow. Replacing it alongside the blade ensures your mower maintains the proper suction needed to lift grass blades for a clean, even cut and effective bagging performance.

The blade is constructed from heat-treated steel. This process increases the metal's hardness and resistance to wear, helping it maintain a sharp edge longer against the typical debris encountered during regular lawn maintenance.

You will generally need a socket wrench to remove the existing bolt and secure the new one. It is also recommended to use a block of wood to safely wedge the blade in place so it doesn't rotate while you are loosening or tightening the screw.

While it depends on the size of your lawn and the frequency of use, most homeowners should inspect their blade at the start of every season. If you notice the blade is dull, chipped, or bent, it is time for a replacement to ensure a healthy cut for your grass.
