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
Runs on a 4.0 Ah battery and cuts up to 1/3 acre with a fully charged battery, depending on grass condition and operator technique.
Gas-free operation eliminates fumes and pull starts, so you press a button and mow.
The deck is claimed to be 35% lighter than steel deck mowers for easier handling.
5 position height adjustment lets you change cut height with one lever.
Switch between mulching and rear bagging without separate tools.
Design and Build Quality
The mower has a 16 inch deck and is claimed to be 35% lighter than steel deck mowers, which can make it easier to push and lift. The listing does not confirm the exact weight, deck thickness, or materials, so this is a relative claim rather than a measured spec.
The controls are simple: push button start, a single lever for 5 height positions, and a rear bag for clippings. The green deck and cordless design fit the Greenworks 40V line, but no additional weatherproofing or durability details are provided.
Performance in Everyday Use
Greenworks states the 4.0 Ah battery can cut up to 1/3 acre with a full charge, but that figure varies based on grass condition and operator technique. The 40V platform means no gas, oil, or pull starts, and the mower works with 75+ other Greenworks 40V tools.
The main limitation is the narrow 16 inch cutting deck, which means more passes and longer mowing time on larger or bumpy yards. Also, this is not a self-propelled mower, so you push the full weight the entire time.
How It Performs: The Evidence

| Cutting width | 16 inch deck | Title specifies 16 inch push lawn mower | 6.5 | Narrow deck adds passes on larger lawns. |
| Height adjustment | 5 positions, single lever | Feature bullet lists single lever height adjust with 5 position height adjustment | 8.0 | Convenient lever but only 5 positions. |
| Clipping management | Mulch and rear bagging | Feature bullet says 2 in 1 system mulch and rear bagging | 7.5 | Covers the basics but no side discharge. |
