Greenworks 40V Cordless Mower Review: Deep Dive


The Greenworks 40v cordless mower comes with oversized wheels (7” rear wheels and 6” front wheels) which enhance improved mobility while mowing. It has a plastic 14-inch cutting deck which provides versatile and efficient operation. Its cutting width is fantastic for smaller yards. 

It is considered one of the lightest electric cordless lawn mowers. It is equipped with an airflow tab which indicates when the bag is full.


The Greenworks 40v cordless push lawn mower runs on a 40V battery system that provides ample mowing performance for your yard projects. The battery system is made up of a maximum capacity of 4Ah Li-ion battery and an optional 40V, 2Ah battery. A particular user observed that the 4AH battery lasts up to 40- 45 minutes while the latter lasts for about twenty minutes. 

The power system is battery-powered, thus, it produces a low-level noise emission. The advantage of this is that you can mow at any time of the day without disturbing your neighbors. 

Cutting performance

The Greenworks 40v cutting deck has a single rotary blade that powers through tall and thick grasses to produce a neat and smooth cut. In fact, it is an efficient lawn mower for st Augustine grass.

You can adjust to five cutting heights via the height adjustment lever located on the front of the mower. This will allow you to cut the grass to your desired height. For a better cutting performance, grasses that are above 4’’ tall should be mowed twice.

The downside of this mower is that it does not perform efficiently on wet grass. The wet grass sticks to the underside of the deck, preventing proper mulching of grass clippings. 

Ease of use

The Greenworks 40v lawn mower is easy to operate. You can easily change batteries while mowing your lawn. In addition, the mower has a fold-away handle for easy and convenient storage during the season. It is equipped with the battery level indicator to provide information about the battery level while mowing.  

Price and warranty

The Greenworks 40v electric cordless mower is reasonably priced. It comes with a four-year warranty. It is important to note that normal wear parts like spark plugs, air filters are not covered by this warranty. 

Special Features

The Greenworks cordless lawn mower comes with a 2-in-1 option. You can mulch or bag. Its metal blade produces a nice and small mulch that restores nitrogen to the soil. 

In addition, it has a bagger which keeps your lawn free from grass clippings. Some users complained about the small bag as one of its flaws.
