Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Starts without a pull cord, making operation simple and quiet.
Uses a 4.0Ah battery included and works with over 75 Greenworks 40V tools like trimmers, blowers, and chainsaws.
The mower is 35% lighter than steel deck mowers, reducing push effort on flat yards.
Offers five cutting height positions with one lever for quick changes.
Supports mulching and rear bagging to handle grass clippings.
Design and Build Quality
The mower uses a 16 inch deck and is described as 35% lighter than steel deck mowers, but the listing does not confirm the actual deck material or total weight. The color is green, and the package includes the mower, battery, and charger.
Build details such as handle folding, wheel size, and deck material are not specified in the source facts. The 3-year limited tool and battery warranty is confirmed and adds some ownership confidence.
Performance in Everyday Use
The 4.0Ah battery is stated to cut up to 1/3 acre with a fully charged battery, but the listing notes this varies based on grass condition and operator technique. The 40V platform also works with over 75 Greenworks 40V tools.
One real limitation is that this is a push mower, not self propelled, so hilly or very thick grass will demand more effort. The 16 inch deck is also smaller than many gas mowers, which means more passes on medium to large lawns.
How It Performs: The Evidence

| Cut Width | 16 inch deck | Title and feature bullet list 16 inch lawn mower | 7.0 | Narrow deck means more passes than mid sized competitors |
| Ease of Start | Push button start, no pull cord | Title mentions push-button start and gas-free operation eliminates pull starts | 9.0 | Simple electric start reduces hassle |
| Weight | 35% lighter than steel deck mowers | Feature bullet states ultra lightweight | 8.0 | Lighter weight helps maneuver, though actual pounds are not confirmed |
| Clipping Options | Mulch and rear bagging | Feature bullet says 2-in-1 system | 7.5 | Useful but lacks side discharge found on many mowers |

Alternatives Worth a Look



This is a straightforward cordless push mower for small to medium yards where light weight and simple starts matter more than pro-grade speed. The included 4.0Ah battery and three year warranty add value, but buyers with thick, bumpy, or sloped lawns may find the 16 inch deck and push design limiting.
