The best Greenworks lawn mower for most lawns is the Greenworks 80V 21" Self-Propelled: the highest-voltage platform the brand sells, a full 21-inch deck, and self-propelled drive, which together cover a large suburban lawn in one go. If you want the same deck width for less money, the 60V 21" Self-Propelled ships as a twin-battery kit, and two packs is what actually determines whether you finish a big lawn rather than the voltage on the label. On a flat lawn, drop the drive and buy the 60V 21" Push. And on a small lawn, the 40V 17" Pushis the one to get — a narrow deck turns more easily, weighs less and costs half as much.
The thing that makes a Greenworks page worth writing is that the brand does not sell one mower range, it sells four battery platforms — 24V, 40V, 60V and 80V — and they do not share batteries with each other. That makes the platform decision more consequential than the mower decision, because whichever one you pick is the one every future Greenworks tool you buy has to belong to. Buy a 40V mower and your trimmer, edger and blower all want to be 40V too.
It also means the voltage numbers are not a quality ladder in the way they look. Higher voltage does deliver more power, which matters in thick or wet grass, but the specification that decides whether you finish your lawn is amp-hours — how much charge you are carrying — and how many packs come in the box. A 60V mower with two 4.0 Ah batteries will out-last an 80V mower with one, which is exactly why the 60V twin kit sits second on this page rather than third.
We have not mown a lawn with any of these machines and we are not going to imply otherwise. The ranking reasons from what each listing publishes — deck width, platform voltage, battery capacity and how many packs are included, and whether the mower is self-propelled or push — see how we pick. Every pick is a live, in-stock listing with a price from the live price layer; we do not list a Greenworks model we cannot actually send you to buy.
Greenworks mowers compared
| Mower | Platform | Deck | Batteries included | Drive | Best for |
|---|
| Greenworks 80V 21" SP | 80V | 21 in | 1 x 4.0 Ah + charger | Self-propelled | Large lawns, most power |
| Greenworks 60V 21" SP | 60V | 21 in | 2 x 4.0 Ah kit | Self-propelled | Best runtime for the money |
| Greenworks 60V 21" Push | 60V | 21 in | 1 x 5.0 Ah + charger | Push | Flat lawns, full deck width |
| Greenworks 40V 17" Push | 40V | 17 in | 1 x 4.0 Ah + charger | Push | Small lawns, easiest to handle |

Pick the platform before you pick the mower
This is the decision that outlasts the purchase, so it deserves the first five minutes. Greenworks batteries are platform-specific: a 60V pack does not run a 40V tool and the other way round. Whichever platform your mower is on becomes the platform your string trimmer, edger and blower should also be on, because the second battery you never have to buy is the real saving in a cordless system.
40V is the homeowner platform and the right choice for a small or medium lawn with a handful of tools. The packs are lighter and cheaper, the tool range is broad, and the 17-inch mower is genuinely pleasant to push. Its limit is power in heavy grass and runtime on a big lawn.
60Vis the sweet spot for most properties, and it is where the mower range is deepest — push and self-propelled, 21-inch decks, single and twin-battery kits. If you have no reason to pick otherwise, pick 60V.
80V is the top of the range and the most power Greenworks puts on a walk-behind. It is worth it on a large lawn, in thick growth, or if you mow less often than you should and the grass is always long. It is the thinnest tool range of the three.
24Vis the small-hand-tool platform. There is no serious 24V lawn mower in this range, so it is not a platform to anchor a mower purchase to — though a 24V pack pair does run the brand’s 48V blower-vacuum, which is worth knowing if you already own 24V tools.
How to choose between these four mowers
Size the deck to the lawn first.Under about 4,000 square feet, the 17-inch deck turns more easily, weighs less and costs half as much — buy it and enjoy it. From 4,000 square feet up, the 21-inch decks remove enough passes per cut to be worth the extra weight. The arithmetic behind those thresholds is in the best lawn mower for a large yard, and it applies to any brand.
Then count the batteries, not the volts. This is where buyers go wrong on cordless mowers generally and on this range in particular. One pack typically covers a normal suburban lawn; a big lawn, long grass or a mulching cut will not finish on one. The 60V twin-battery kit exists for precisely that case and is usually the best runtime-per-dollar in the range. If you are near the limit, buy the kit with two packs rather than the higher voltage with one.
Add self-propelled only if your lawn slopes.On flat ground the drive is a convenience you can skip and keep the money — a 21-inch push mower is perfectly manageable, which is what the 60V push model is for. On a real gradient the drive is what determines whether you keep mowing or start putting it off. The broader case is in the self-propelled roundup; if your lawn is flat, the push mower roundup covers the alternatives.
Factor in the charger, which nobody reads. Charge time varies considerably across the platforms, and on a lawn that takes two packs it decides whether you can finish in one afternoon or have to wait. If you are buying a single-battery kit for a lawn at the edge of its range, a second pack is a better upgrade than any other money you could spend here.
Decide whether you want to mulch.Greenworks does not state a 3-in-1 mulching deck on these particular listings, so if returning clippings to the lawn matters to you, check the model’s own specification before buying, or look at the mowers that do state it in the best mulching lawn mower. We will not claim a mulching capability a listing does not publish.
What Greenworks is good at, and what it is not
The honest case for the brand is breadth and value. Greenworks covers the whole lawn in one battery ecosystem — mowers, trimmers, edgers, blowers, even a corded dethatcher — and it does so at consistently lower prices than EGO, which is its nearest equivalent. For a homeowner who wants one platform and does not want to think about it again, that combination is hard to beat, and it is why Greenworks tools appear across several categories on this site.
The honest case against is that build quality is good rather than exceptional, and the premium alternatives are genuinely better made. If you want the best-built cordless walk-behind rather than the best value, our electric mower roundup ranks the whole field across brands and does not put Greenworks top of it. That is not a contradiction of this page — this page answers “which Greenworks mower”, and a buyer already committed to the platform is asking a different question than a buyer choosing between brands.
The other thing worth knowing is where Greenworks does not compete. There is no Greenworks riding mower or zero-turn in this registry, so if your lawn has outgrown a walk-behind the brand is not the answer — see the best riding lawn mower instead.
Building out the rest of the platform
Once the mower fixes your platform, the rest of the lawn gets cheaper, because every additional tool can be bought as a bare tool or shares the packs you already own. The 40V platform in particular has the companion tools this site already ranks: the 40V 16" string trimmer for edges and around obstacles, and the 40V 8" edger for a cut line along paths and drives.
Two things the battery platform does not cover, and should not be confused with it: the brand’s 14-inch dethatcher is corded rather than cordless, so it runs off an outlet regardless of which platform you chose. And no battery decision helps with the parts of lawn care that are not tools at all — what you feed the lawn and what you seed it with will do more for how it looks than any mower on this page.
Who should skip these
Skip Greenworks if you already own batteries from another cordless platform. The saving from reusing packs you have is usually larger than the difference between brands, and starting a second ecosystem is the most expensive thing you can do in cordless tools.
Skip the 80V model unless you have a large lawn or heavy growth. It is the most powerful walk-behind here and on a normal lawn cut on a normal schedule you will not reach the limits of the 60V, which costs less and has two packs in the box.
And skip all of them if your lawn is over about three quarters of an acre. No walk-behind is the right tool at that size, whatever the brand — an hour and a half of walking every week is not a problem a bigger battery solves.
