Greenworks 40V 16in Push Lawn Mower, 4.0 Ah Battery and Charger

This 40V cordless push mower is built for homeowners with smaller yards who want to skip the gas, oil and pull-cord routine. With a 16-inch cutting deck and a 4.0Ah battery included in the box, it targets lots up to about a third of an acre, making it a practical option for typical suburban front and back yards combined.

The lightweight design is one of the more meaningful practical advantages here. The deck is made without steel, which the manufacturer says results in a 35 percent weight reduction compared to steel deck mowers. For anyone who finds a heavy mower tiring to push, especially on sloped or uneven ground, that difference shows up every single mowing session. Setup and storage are also simpler when the machine itself is not a burden to lift or carry.

Height adjustment uses a single lever that moves through five positions, which means you are not fiddling with individual wheel clips on each corner. The 2-in-1 system handles both mulching and rear bagging, so you can mulch clippings back into the lawn one week and collect them the next depending on your preference or grass conditions. The 40V battery is also compatible with more than 75 other tools in the same platform, including trimmers, blowers and chainsaws, which adds real value if you plan to expand your outdoor tool set over time.

A few trade-offs are worth naming. The 16-inch deck is narrower than many walk-behind mowers, so larger yards will require more passes and more time. Battery runtime is listed as up to a third of an acre, and the listing notes that grass conditions and operator technique affect that figure. The listing does not specify how long the battery takes to recharge between uses, which is worth checking if your yard is on the larger end of that range.

Verdict: This mower suits homeowners with a yard up to about a third of an acre who want a lightweight, low-maintenance cordless option. It is especially compelling if you already own or plan to buy other 40V tools from the same platform, since the battery does double duty across the lineup.

A great fit if you:

• Have a yard up to roughly a third of an acre and want to finish mowing on a single charge
• Find heavy steel deck mowers tiring to push and want something noticeably lighter
• Already own or plan to buy other 40V cordless outdoor tools and want shared batteries
• Prefer skipping gas, oil changes and pull-cord starting entirely
• Want the flexibility to mulch clippings or collect them in a rear bag depending on the day

Consider something else if you:

• Have a yard larger than a third of an acre, where a single charge may not be enough
• Need a wider cutting deck to reduce the number of passes on an open lawn

Does the battery and charger come included?
Yes. The package includes a 4.0Ah 40V battery and a charger, so you can start mowing without a separate purchase.

How large a yard can it handle on one charge?
The manufacturer lists up to a third of an acre per fully charged battery, though actual coverage varies based on grass conditions and how you operate the mower.

Can I use this battery with other tools I already own?
The 40V battery is compatible with more than 75 tools in the same 40V platform, including trimmers, blowers and chainsaws, so it can power other tools from that lineup.

What does the warranty cover?
A 3-year limited warranty covers both the tool and the battery, which is longer than many entry-level mower warranties.
