The electric lawn mower finally got good enough this spring. Cordless decks used to feel like a compromise for green-minded buyers, but now they’re the first thing we’d point most homeowners toward, and the specs back that up. People who would’ve laughed off a battery mower two years ago are walking past the gas aisle at Lowe’s.
The math behind the switch changed too. Self-propelled cordless decks now start under $500, last as long as gas on a typical quarter-acre, and 80V or dual-battery models can finish a half-acre that used to send buyers back to a Honda. State rebates pile on more savings: Californians in South Coast AQMD’s four-county jurisdiction (Los Angeles, Orange, Riverside, and San Bernardino) can get up to $250 back per piece with a gas trade-in, and Coloradans get 30 percent off at the register through 2026 at participating retailers like select Ace Hardware stores, Murdoch’s Ranch & Home Supply, and McGuckin Hardware. New York lawmakers passed a similar bill (S.1574 / A.2657) in April 2026, but it’s still waiting on the governor’s signature, and as drafted it only covers commercial landscapers, towns, and schools.
We’ve tested cordless mowers for three seasons running, and this is the first year we’d hand a serious buyer a battery mower with no asterisks. If you’ve been waiting for the right year to switch, this is it.
The best electric lawn mowers of 2026 at a glance
Here’s how the five picks below compare on deck size, battery, runtime, drive, and price. Every number traces back to a manufacturer page or retailer listing pulled in May 2026.
| Model | Deck | Battery | Runtime | Drive | Price |
|---|---|---|---|---|---|
| EGO LM2156SP | 21 in | 56V, 10.0Ah | Up to 75 min | Self-propelled | $1,399 |
| Ryobi RY40HPLM07K | 20 in | 40V HP, 6.0Ah | Varies by load | Self-propelled | From $449 at Home Depot |
| Greenworks Pro 80V LM2138 | 21 in | 80V, 4.0Ah | Up to 60 min | Push | Below the $629.99 Gen 2 SP at Costco |
| Milwaukee 2823-22HD | 21 in | M18, two 12.0Ah | Up to 60 min | Self-propelled | $2,398 |
| DeWalt DCMWSP256U2 | 21 in (533mm) | 20V Max XR, two 10.0Ah | Up to 80 min | Self-propelled | About $259 |
EGO Power+ Select Cut XP LM2156SP: the all-around pick
If you’re cutting between a quarter-acre and a half-acre, this is the one. The 21-inch deck, brushless motor, and rear-wheel-drive self-propulsion power through thick spring grass without slowing down, and the Select Cut system uses three interchangeable lower blades you can swap for mulching, bagging, or side-discharge.
Price: $1,399
Where to Buy: Amazon
EGO rates the LM2156SP at up to 75 minutes of runtime on the included 10.0Ah 56V Arc Lithium battery, and that’s held up in our spring testing. Pricing varies by retailer and battery configuration, and the smaller LM2135SP (7.5Ah pack, up to 60 minutes per EGO’s spec) is the cheaper way into the EGO system if you don’t need the 10.0Ah battery.
- Deck: 21 inches, multi-blade Select Cut system
- Battery platform: EGO 56V Arc Lithium, 10.0Ah included
- Drive: rear-wheel self-propelled with Touch Drive variable speed
- Best lot size: quarter to half acre
- Where it falls short: weight lands around 75 lb per Lowe’s spec, still awkward on steep slopes
Ryobi 40V HP Brushless 20-inch Self-Propelled: the gas-mower swap
This is the one to grab if you’re replacing a 150cc gas mower and don’t want to spend EGO money.
The 20-inch deck pairs with a brushless motor and Ryobi’s load-sensing tech, which bumps blade speed when the grass gets thick. It stops bogging the second it hits a wet patch you didn’t see, which is the biggest complaint about cheaper cordless mowers.
Price: $519.95
Where to Buy: Amazon
Home Depot lists the self-propelled kit (model RY40HPLM07K) at $479 with a 6.0Ah battery and charger, and the page shows a $449 sale price as of this writing. Ryobi’s 40V battery also fits its blower, trimmer, and chainsaw, so if you already own Ryobi tools you can buy just the bare mower and a charger.
- Deck: 20 inches, brushless motor with load-sensing
- Battery platform: Ryobi 40V HP
- Drive: self-propelled rear-wheel
- Best lot size: quarter-acre or smaller flat lots
- Where it falls short: runtime on a single battery is tighter than EGO’s flagship, plan for a swap mid-cut on larger lots
Greenworks Pro 80V 21-inch Brushless: the quiet push for smaller lots
If your yard is under a quarter-acre and you don’t need self-propulsion, this is the best mix of power and quiet at this price. The 80V brushless motor matches what Greenworks calls the power of a 160cc gas engine, but at a noise level that won’t earn a 7 a.m. complaint from the neighbor.
Price: $479.99 (From $699.99)
Where to Buy: Amazon
The 80V 21-inch push-only kit (LM2138, 4.0Ah) comes in well below the self-propelled Gen 2 version, which sells for $629.99 at Costco with two batteries and a rapid charger.
The trade-off is simple: the push version weighs about 60 pounds per Greenworks’ spec, well under the 75 to 90 pounds of self-propelled flagships, but you’re pushing the mower yourself every pass.
- Deck: 21 inches, brushless
- Battery platform: Greenworks Pro 80V
- Drive: push (no self-propulsion on this config)
- Best lot size: under a quarter-acre, flat
- Where it falls short: no self-propulsion, larger lots will wear you out
Milwaukee M18 Fuel 21-inch Dual Battery: built for half-acre and beyond
This one earns its spot because it pushes past the size where cordless mowers usually stall out. It runs two 12.0Ah M18 Fuel packs in series for 36V of power, and the kit sells for $999 at Home Depot, with a regular price closer to $1,099. That puts it in real competition with mid-tier gas riding mowers for lots between half an acre and three-quarters.
Price: $2,398.99
Where to Buy: Amazon
The kicker is the M18 system itself. If you already own Milwaukee tools, you’re not buying batteries, you’re buying a deck and a charger, and that changes the real cost more than the spec sheet shows.
Where it pays off is the swap math. Two 12.0Ah packs cover up to a half-acre cut in normal spring grass per Milwaukee’s own spec, and a third pack drops in if you need to go bigger without missing a beat.
- Deck: 21 inches, brushless
- Battery platform: Milwaukee M18 (dual 12.0Ah included)
- Drive: self-propelled
- Best lot size: half-acre to three-quarter acre
- Where it falls short: heavy, and the price only makes sense if you already own Milwaukee tools
DeWalt 20V Max XR 2x20V Brushless: the platform-loyalty pick
DeWalt’s 2x20V setup uses two 20V Max XR batteries in succession (one drains, then the second takes over), and it’s the right pick for anyone already deep in the DeWalt system. The DCMWSP256U2 brushless self-propelled kit sells for about $649 at major retailers, with the battery cost already paid for if you’ve got a stack of XR packs at home.
Price: $259.97
Where to Buy: Amazon
What it does well is share batteries. The same packs that run your impact driver, circular saw, and blower drop right into the mower, and that’s the whole pitch. DeWalt rates the DCMWSP256U2 at up to 80 minutes per charge on a pair of 10.0Ah XR packs, which actually beats both EGO and Milwaukee on paper, so the real trade-off is what you pay to get into the DeWalt system rather than how long the mower runs.
- Deck: 21 inches (533mm), brushless
- Battery platform: DeWalt 20V Max XR (dual)
- Drive: self-propelled
- Best lot size: quarter-acre with existing DeWalt batteries
- Where it falls short: the value really only lands if you already own DeWalt 20V Max tools; standalone buyers can get more mower per dollar elsewhere
How to pick by lot size and slope
The fastest way to pick is to ignore brand loyalty and start with two things: square footage and slope. Under 5,000 square feet on flat ground, a 17- to 20-inch push mower from Greenworks or Ryobi does the job for under $400.
Between 5,000 and 15,000 square feet, you want a 21-inch self-propelled brushless deck with at least a 56V or 80V battery. EGO’s LM2156SP and Ryobi’s 40V HP both fit here, and the choice usually comes down to which battery you already own.
Over 15,000 square feet, or anywhere with real slope, you want a dual-battery setup or Milwaukee’s M18 mower. Anything close to an acre still benefits from a backup pack, and we’d budget for one even when the marketing says you don’t need it.
Who should still keep a gas mower
The honest answer is that cordless is now the default for most US lawns, but a small group of buyers should still keep gas in the shed. If you’re cutting more than an acre and would rather fill one tank than swap batteries, gas is still the easier path.
The other case is steep slopes with thick, wet grass on a regular basis. A 160cc gas engine and a heavy steel deck still chew through that faster than any cordless mower we’ve tested, and you can refuel in 30 seconds. Most buyers don’t fall into either group, but the ones who do already know it.
Frequently asked questions
Are electric lawn mowers worth it in 2026? For most US lawns under three-quarters of an acre, yes. Self-propelled cordless decks now start under $500, the runtime on a single charge covers a typical quarter-acre, and state rebates in California and Colorado can knock 30 percent or more off the sticker. The math only stops working past an acre or on steep wet slopes where gas is still faster.
How long does an electric lawn mower last on one charge? Runtime depends on deck size, battery capacity, and grass thickness. EGO rates the LM2156SP at up to 75 minutes on a 10.0Ah pack, Milwaukee rates the 2823-22HD at up to 60 minutes on two 12.0Ah packs, and DeWalt rates the DCMWSP256U2 at up to 80 minutes using two 10.0Ah XR batteries in succession per the brands’ product pages.
What’s the best electric lawn mower for a half-acre yard? EGO’s LM2156SP is the all-around pick at this size. If you want more headroom or already own Milwaukee tools, the M18 Fuel 2823-22HD pushes into three-quarter acre territory using two 12.0Ah packs in series for 36V.
Do electric lawn mower rebates require a gas trade-in? It depends on the state. California’s South Coast AQMD program requires you to scrap your old gas mower at an approved dismantler. Colorado’s 30 percent state credit does not require a trade-in. The pending New York program (S.1574 / A.2657) only covers commercial landscapers, towns, schools, and other institutions as drafted.
Are electric lawn mowers self-propelled? Self-propelled cordless models exist across every major brand. EGO, Ryobi, Greenworks, Milwaukee, and DeWalt all sell them. Push-only versions cost less and weigh roughly 15 to 30 pounds less than their self-propelled siblings per the brands’ published specs.
