Best Cordless Lawn Mower
Cordless mowers are decided by yard size and nothing else first. Under a third of an acre, a 16 to 17 inch push mower on a single battery is enough and anything bigger is wasted money. Over a third of an acre, you need a 21 inch deck, self-propelled drive and ideally two batteries.
The second thing that matters is the battery platform, because the battery is most of the cost. If you already own tools from EGO, Greenworks or Makita, buying into the same platform is usually the right call even if another mower looks slightly better on paper. One note on availability: Ryobi mowers are Home Depot exclusives and Kobalt is Lowe's, so neither appears here.
Quick answer
For most yards the EGO Power+ LM2135SP is the best cordless mower, with a 21 inch deck, self-propelled drive and the strongest battery platform. The Greenworks 80V self-propelled model does the same job for less. For a small yard under a third of an acre, the Greenworks 40V 16 inch push mower is enough and far cheaper.

What Matters Most for a Cordless Lawn Mower
Deck width sets how many passes your lawn takes, and 21 inches is the practical standard for anything over a third of an acre. Battery capacity, measured in amp hours and volts, sets runtime, and the honest way to think about it is that thick or damp grass can cut runtime roughly in half against the figures in marketing material. Two batteries matter more than one large one, because you can swap and keep mowing. Self-propelled drive stops being a luxury the moment your lawn has any slope, and on flat ground under a third of an acre it is genuinely unnecessary. Deck material is the last consideration: steel takes more abuse, plastic composite never rusts and is lighter to push. Then check the battery platform you already own, since matching it saves the single most expensive part.

EGO Power+ 21 in Cordless Self-Propelled Lawn Mower Kit, LM2135SP
Best OverallPros
- EGO's 56V platform is the strongest cordless outdoor range, so the battery carries over to trimmers and blowers
- Self-propelled drive makes slopes and longer runs genuinely easier rather than just faster
- Cutting power holds up in damp and thicker grass better than most 40V class mowers
Cons
- Costs noticeably more than the Greenworks and Skil equivalents
- A single battery means a swap is not possible unless you buy a second
The default recommendation, and the platform is the main reason. A cordless mower is really a battery purchase, and EGO's 56V range covers trimmers, blowers, chainsaws and snow throwers, so the expensive part is reusable. The mower itself is well matched to a typical suburban lawn: a 21 inch deck keeps pass count down, and the self-propelled drive matters on any slope. Buy a second battery if your lawn is near the top of its range.
Greenworks 80V 21 in Self-Propelled Lawn Mower, 4.0 Ah Battery and Charger
Best ValuePros
- A 21 inch self-propelled mower at a meaningfully lower price than the EGO
- Higher nominal voltage delivers strong cutting torque in thicker grass
- Greenworks 80V range also covers trimmers, blowers and chainsaws
Cons
- A 4.0 Ah battery is modest for a 21 inch deck, so large lawns will want a second
- Greenworks tool range is not as broad as EGO's, which matters if you plan to expand
The sensible value choice, and the compromise is runtime rather than capability. The deck, the drive and the cutting power are all in the same class as the lead pick; what you get less of is battery. On a quarter to a third of an acre that is fine. On anything larger, budget for a second battery and the total still comes in below the EGO.
Greenworks 60V 21 in Self-Propelled Lawn Mower, Two 4.0 Ah Battery Kit
Best RuntimePros
- Two batteries in the box is the real fix for runtime anxiety, since you swap and keep going
- Buying a kit with two batteries is cheaper than buying the mower and a battery separately
- A 21 inch self-propelled deck handles a large lawn in sensible time
Cons
- The 60V platform is separate from Greenworks 80V and 40V, so batteries do not interchange between them
- Two 4.0 Ah batteries is more total capacity but neither is large on its own
This is the pick if your honest answer to how big your lawn is sits above a third of an acre. Runtime is the thing people get wrong about cordless mowers, and the fix is not a bigger battery, it is a second one, because you can charge one while using the other. Watch the platform though: Greenworks sells 24V, 40V, 60V and 80V lines and the batteries do not cross over, so pick the line you want to stay in.
Makita XML11CT1 36V, 18V X2, LXT 21 in Self-Propelled Lawn Mower Kit with 4 Batteries
Best for Makita OwnersPros
- Runs on the same 18V LXT batteries as Makita's cordless tool range, which many trades already own
- Four batteries in the kit means real runtime and two pairs to rotate
- Build quality and the automatic torque drive system are aimed at commercial use
Cons
- Running two 18V batteries in series is less efficient than a single high-voltage pack
- Expensive as a kit, and only makes sense if the LXT batteries have other uses
A specific recommendation for a specific person: someone with a drawer of Makita 18V LXT batteries. For them the economics are good, because the batteries are shared with everything else they own. For anyone outside the LXT ecosystem, a dedicated high-voltage platform like EGO or Greenworks delivers more mower for the money. The build is genuinely commercial grade.
Toro Recycler 21 in Deck 60V Max Steel Push Lawn Mower
Best Steel DeckPros
- Steel deck takes impacts and abrasion that crack a plastic composite deck
- Toro's Recycler mulching system is long established and handles clippings well
- Folding lockable handle stores upright, which saves real garage space
Cons
- Steel is heavier to push, and this is a push mower with no drive assist
- Steel can rust where the coating is damaged, so it needs cleaning after wet use
The pick if your lawn has hidden roots, stones or edging that punish a deck. Plastic composite decks never rust and are lighter, but they crack; steel dents and keeps going. Being a push mower, it suits flat lawns rather than slopes, and the weight of steel is felt. The folding handle is a bigger practical benefit than it sounds if your mower lives in a crowded garage.
Skil PWR Core 40 Brushless 40V 20 in Self-Propelled Mower Kit with 6.0 Ah Battery
Best Budget Self-PropelledPros
- Self-propelled drive at a price where most mowers are push only, which matters on any slope
- A 6.0 Ah battery is generous capacity for a 40V class mower
- Brushless motor, so efficiency and motor life are better than brushed budget mowers
Cons
- A 40V platform has less torque headroom than 56V to 80V mowers in thick wet grass
- Skil's outdoor tool range is smaller, so there is less reason to stay on the platform
Good value for a specific situation: a sloped lawn and a limited budget. Self-propelled drive is the feature that disappears first at lower prices, and getting it here along with a 6.0 Ah battery is a genuine win. Be realistic about the 40V class in heavy conditions, where it will bog down sooner than the 56V and 80V mowers above. On ordinary dry grass it is perfectly capable.
Greenworks 40V 16 in Push Lawn Mower, 4.0 Ah Battery and Charger
Best for Small YardsPros
- A 16 inch deck is light, easy to turn in small gardens and fits through a narrow gate
- A 4.0 Ah battery is genuinely enough for a small lawn on one charge
- Costs a fraction of the 21 inch self-propelled mowers and does the job just as well at this size
Cons
- A 16 inch deck means many more passes on anything over a third of an acre
- Push only, so slopes are hard work
The honest recommendation that saves people the most money. If your lawn is small, a 21 inch self-propelled mower is heavier, harder to manoeuvre around beds and more expensive to no benefit. A 16 inch deck turns tightly, goes through a side gate and finishes a small garden on one battery. Buy this and spend the difference on a decent trimmer.
Size the mower to the yard, not to the budget
Under a third of an acre, a 16 to 18 inch push mower on a single battery finishes the job and is easier to manoeuvre around beds and through gates. A third to two thirds of an acre wants a 21 inch deck, and self-propelled drive becomes worth it. Above that, you want a 21 inch deck, self-propelled drive and two batteries so you can swap mid mow. Buying a large self-propelled mower for a small lawn is the most common and most expensive mistake in this category, because you pay for capability you then have to push around tight corners.
Battery platform is the real purchase
Batteries are most of the cost of a cordless outdoor tool collection, and they do not cross brands. They often do not even cross lines within a brand: Greenworks sells 24V, 40V, 60V and 80V ranges whose batteries are not interchangeable. So if you already own EGO, Greenworks or Makita batteries, that platform is usually the right choice even when another mower looks better on paper. If you are starting fresh and intend to add a trimmer, blower and maybe a chainsaw, pick the platform with the range you want rather than the single best mower.
Runtime, and why two batteries beat one big one
Marketing runtime figures assume dry grass at a moderate cutting height. Thick, damp or long grass can cut that roughly in half, and a battery that was adequate in June can run out in a wet spring. The reliable fix is a second battery rather than a bigger one, because you can charge one while mowing with the other, which effectively removes the limit. Kits that include two batteries are usually cheaper than buying the mower and a second battery separately, which is why two-battery kits are worth looking at even if the total capacity sounds similar.
Deck material, drive and the small things that matter
Steel decks resist impact and abrasion and will rust if the coating is damaged; plastic composite decks never rust and are lighter but can crack. On rough ground with roots or stones, steel lasts longer. Self-propelled drive is a necessity on slopes and genuinely unnecessary on a small flat lawn. Beyond that, two details repay attention: a folding handle that lets the mower store upright, which matters in a crowded garage, and whether the mower mulches, bags and side-discharges, since mulching returns nitrogen to the lawn and saves you bagging.
FAQs
What is the best cordless lawn mower?
For most suburban lawns, the EGO Power+ LM2135SP, because it pairs a 21 inch self-propelled deck with the strongest cordless outdoor battery platform, so the expensive part carries over to other tools. The Greenworks 80V self-propelled model offers much the same capability for less, with a smaller battery.
How big a cordless mower do I need?
Match deck width to lawn size. Under a third of an acre, a 16 to 18 inch push mower is enough and easier to handle. A third to two thirds of an acre suits a 21 inch deck with self-propelled drive. Above that, you want a 21 inch self-propelled mower and two batteries so you can swap partway through.
How long does a cordless mower battery last?
It depends far more on grass conditions than on the battery. Manufacturer figures assume dry grass at a moderate height, and thick, long or damp grass can roughly halve the real runtime. Rather than chasing a bigger battery, most people are better served by a second battery they can swap in.
Are cordless mowers powerful enough for thick grass?
Modern 56V to 80V mowers handle thick grass well, and the 40V class will bog down sooner in heavy wet growth. Raising the cutting height, mowing more often and slowing your walking pace all help more than people expect. If your lawn is routinely long and damp, buy into a higher voltage platform rather than a bigger battery.
Do I need a self-propelled mower?
On any slope, yes, because pushing a 21 inch mower uphill is genuinely hard work. On a flat lawn under a third of an acre it is unnecessary and adds weight, cost and complexity. Self-propelled drive is also helpful on large flat lawns simply because of the distance covered.
Why are Ryobi mowers not on this list?
Ryobi outdoor power equipment is sold through Home Depot as an exclusive, and Kobalt through Lowe's, so neither is genuinely available on Amazon. Listings that appear under those names are usually third-party batteries or mowers described as compatible with that brand's batteries rather than the brand's own machines.
Is a steel or plastic mower deck better?
Steel resists impact and abrasion better, which matters on rough ground with roots or stones, but it is heavier and will rust where the coating is damaged. Plastic composite never rusts and is lighter to push, but can crack under impact. For a smooth suburban lawn, composite is fine; for rough ground, choose steel.
Can I use the same battery for my mower and other tools?
Only within the same platform, and often only within the same voltage line of the same brand. Greenworks, for example, sells 24V, 40V, 60V and 80V ranges that do not interchange. This is why the platform matters more than the individual mower if you plan to own a trimmer and blower too.
Should I mulch or bag my clippings?
Mulch in most cases, because the clippings break down and return nitrogen to the lawn, which reduces how much you need to feed it. Bag when the grass is very long, when it is wet enough to clump, or when you are clearing leaves. Most mowers here do both, and switching is a matter of fitting or removing the bag and plug.
Our verdict
Buy the EGO Power+ LM2135SP if you want the best platform and a 21 inch self-propelled deck, or the Greenworks 80V self-propelled model to save money and add a second battery later. For a lawn over a third of an acre, the two-battery Greenworks 60V kit removes the runtime problem outright. If your lawn is small, buy the Greenworks 40V 16 inch push mower and do not spend more, and choose the Toro Recycler instead if your ground is rough enough to damage a deck.
