Looking for a lawn mower that doesn’t contribute to climate change, and that won’t wake up your neighbor’s sleeping baby? We rate the best emission free, electric, lawn mowers on the market today, plus tips for buying the right electric lawn mower.
Gas lawn mowers degrade air quality
Think your choice of lawn mower doesn’t matter?
According to research published by Michigan State, “mowing the average lawn in the U.S. creates as much air pollution as driving the family car on a 200-mile trip,” which has many of us looking for greener options. We rated, and tested, emission free lawn mowers and listed our top picks below
The United States Environmental Protection Agency (EPA) places restrictions on emissions from lawnmowers, but there are no emission-free gas lawn mowers. Gas mowers also become less efficient and pump out ever-greater emissions the older they get.
As for electric mowers, these are tankless and instead rely on a cord or battery. Corded mowers have no mowing time restriction as they draw energy from your main electricity hookup. For battery models, battery time means how long you can use an electric mower before having to charge the battery again.
Most battery-powered lawn mowers are powered by lithium-ion batteries, which are just bigger versions of the lithium batteries in our laptops and cellphones. You can store a lot of energy in a lithium battery compared to older types of batteries, which is why electric lawn mowers are now possible and, indeed, comparable in power to a gas-powered lawnmower.
Unfortunately, lithium batteries are expensive and deteriorate over several years, with their capacity decreasing as the cells in the battery die off. It’s a good idea, therefore, to have a spare battery and to replace the battery every few years to ensure good performance.
Avoid second hand electric lawn mowers
Beware second-hand electric mowers with older batteries; the mower itself may be sold cheap compared to a new model, but the included battery or batteries may be next to useless and cost more than the mower to replace.

The research
Over the past nine mowing seasons, we’ve spent more than 120 hours researching nearly 250 mowers, interviewing experts, and extensively testing some of our top picks.
An invaluable source has been Roy Berendsohn, a Popular Mechanics lawn mower guru who has more than 20 years of experience testing and writing about mowers. If Berendsohn isn’t writing about mowers, he’s often being interviewed about them (see here and here).
We’ve interviewed landscapers, including Chad Crosby of West Michigan Lawn Services and Paul Koehler of Koehler Landscape Construction Services. We’ve called people at lawn mower retail/service outlets, like Nick Ortiz at Kellam Lawn Mower in Glen Mills, Pennsylvania, and Boston Lawnmower Company’s David (who asked that his last name be withheld). We’ve talked to product managers at Honda, Toro, Troy-Bilt, Ego, Cub Cadet, and other manufacturers.
Personally, I maintain a rural property in New Hampshire that is far too large for a push mower to cover but that does provide ample room to test our recommendations. This guide’s editor, Harry Sawyers, assists with testing mowers on his LA property and draws from his previous experience as a professional landscaper.
Who this is for
If you want to be able to stand the sight of your yard this summer, you’re going to need a lawn mower. Anything larger than a half-acre gets into riding-mower territory, but a self-propelled push mower is perfect for a half-acre or less. Going at a pace of about 3 mph (roughly average walking speed), it will take about an hour to cut this amount of grass. (If you have a particularly small lawn, a reel mower is an option—but it’s quite hard work.)
If you already own a gas mower that’s less than a decade old, you will probably not notice a tremendous difference by upgrading to a newer gas mower. Upgrading to a cordless model is a more noticeable change you could immediately appreciate.
The Best Reel Mower for Your (Small) Lawn
After 30 hours researching and testing reel mowers, we think the Scotts 2000-20 20-Inch Classic Push Reel Lawn Mower is the best pick for manual lawncare.
How we picked and tested
As a result of our years of lawn mower evaluation, we’re sure that most people will be happiest with a self-propelled, electric cordless option. Honestly, it all comes down to convenience. Every single element of a gas mower that is considered a nuisance—from the fiddly start-up to the annual maintenance schedule—is gone. Cordless mowers start with the push of a button, are easier to maneuver, and don’t need oil changes, gas, spark plugs, or air filters. They’re much quieter, they don’t smell, they don’t produce emissions, and they’re easier to store in the off-season. The run time has limitations, and charge times can be slow, but the latest models close the performance gaps between cordless and gas.
All that said, there are many capable—and several excellent—gas mowers available. Whatever type of mower you need, here are the criteria we feel matter most in making a selection:
Rear-Wheel Self-propulsion: Self-propelled mowers make life easier. With the mower moving itself across the lawn, all you have to do is throttle and steer, rather than forcing the mower’s full weight up every incline and over every bump. Self-propelled cordless mowers are all rear-wheel drive (RWD), which is preferred over front-wheel drive (FWD), because the mower’s traction improves as the grass bag fills and adds weight over the rear wheels. A self-propulsion feature adds to a mower’s price, but it’s a feature we feel is well worth it, and this requirement doesn’t narrow the field by a whole lot. It does, however, weed out the most bare-bones machines.
Performance as a mower: We researched which mowers could perform the best from a lawn-care perspective—which could make cleaner cuts in grass or promote turf health. We’ve measured this performance firsthand over years of long-term testing and in tests of new contenders against our established recommendations.
User interface and features: In years of tests, we’ve found most midrange mowers perform at a comparable level; most can cut the grass just fine. That led us to place an emphasis on user interface features—how difficult is it to adjust the push-bar height, or to raise and lower the mowing deck? Can you intuitively control and adjust the self-propulsion? Is the bag a pain to put on and take off? Are there other design details that make startup smoother, reduce engine maintenance, or make storage easier?
Cost: We looked at cost in terms of long-term value. Gas mowers are cheaper up-front, generally, but they carry long-term costs that cordless mowers avoid. Those include supplies (like gas, oil, stabilizers, air filters, and spark plugs) and the time and labor of caring for one: getting gas, changing the oil, and emptying the tank at the end of the season. With cordless mowers, a large percentage of the price tag is the battery. Most companies offer a series of outdoor tools (leaf blowers, string trimmers, hedge trimmers, etc.), all compatible with the same battery. And they cost less if you buy them without a battery. So for a high cost up-front, a cordless investment may open the door for an affordable expansion into that manufacturer’s other tools.
Charge time and run time: For cordless candidates, we looked at these two primary factors, which determine whether a battery will be adequate or frustrating. Because these two elements are so important, we looked only at mowers that used at least a 40-volt battery.
and reputation: The best mowers out there have proved satisfying for the most number of people for the longest amount of time. That led us to closely consider the differences among a smaller group of about 50 established, well-regarded models from major brands, often covered by comparable warranties of about three to five years.

For the best in convenience, battery run time, cut quality, and value, we recommend the Ego Power Select Cut Mower LM2135SP. Compared with a gas mower, it’s quieter, doesn’t create exhaust, and requires almost no maintenance. Among other cordless models, the Ego LM2135SP has among the longest run time and shortest charge time. This Ego has a redesigned control interface that allows you to control the propulsion with either hand. It also cuts with two blades, making for a finer cut and better mulching. Rounding out the features are two forward-facing LED lights, an easy-to-use cutting-height adjustment, and a battery port that faces the battery gauge toward the operator. The battery, which is good for a solid hour of mowing, is compatible with Ego’s other lawn tools, such as the company’s leaf blower, chainsaw, and string trimmer.
Most people report getting roughly 60 minutes of run time from a full charge of the Ego’s 56-volt, 7.5 Ah battery, which is included with the purchase. We confirmed the run-time figures in tests of this pick and our runner-up in March 2019 and in 2020. In several hour-long sessions of strenuous cutting on tough grass in Los Angeles, running this mower across hills (some of which were steeper than its recommended 15-degree max), the battery never died before we expected it to. If anything, it exceeded the hour-long window by about 10 to 15 minutes. An added bonus: Once the battery was too low to power the mower blades, it still had enough juice to operate the self-propulsion function, letting us drive the mower back to the charger. Compared to older Ego batteries, this one has a ring of lights that give you an approximate gauge of the remaining charge (the previous generation communicated with a red light only when the battery got critically low). The battery regularly recharges in 60 minutes or less. (Recharge time is another advantage for Ego, as competitors’ charge times range from an hour and a half up to almost five and a half hours.)
In the mowing tests, the two-bladed Ego showed a superior cut-quality compared with our runner-up, and this is the primary reason we’d choose this model over the older version. We’ve put the mowers on some rough tufts of knotty crabgrass, knee-height rye grass, and thick purple stalks of weeds, and although the runner-up never bogged down, the LM2135SP did a better job of lifting overgrown grasses as it cut, mincing up fine mulch and effectively cutting through tall growth without pushing the grass flat. This second blade elevates the Ego into some territory that was formerly exclusive to mowers like the highly regarded Honda HRX series, making the case for cordless that much stronger.

Controlling the Ego is easy and intuitive. As with many mowers, the Ego has a metal bar (called a bail) that’s held against the handle to activate the blades. To activate the RWD self-propulsion, you press one of two buttons in the upper corners of the handle, and a central dial controls the mower’s speed. A couple of subtle changes set this mower apart from other models: The speed-control system can be operated with your thumbs on either hand—a more versatile setup than the single, oversize, right-handed trigger on the runner-up. Second, although the mower can move at a brisk pace if you want it to, the slowest speed setting available is unusually slow. This is quite handy if you’re backing in and out under a tree or in another tricky area, if you’re mowing across a hill and taking care not to let the mower slide or roll away, or if you just need to take it slow to make sure you’re not about to mow over an obstruction.
Random aside: Without the stink of gas engine exhaust in your face, the smell of mowing the grass while using Ego is entirely different and much more pleasant; unfortunately, the allergens are exactly the same.
The Ego has a number of other convenience features. The headlight, something not found on gas mowers, gives some illumination as the day starts to end. The single-adjust height control, a rarity on gas mowers, allows you to set the cutting height with a single lever. On most gas mowers, cutting height has to be adjusted at each individual wheel. The Ego has seven cutting heights, between 1½ to 4 inches—a wider range than on most cordless mowers, which top out at around 3½ to 3¾ inches.
Flaws but not dealbreakers
Although the two-handed self-propulsion control is a more convenient setup than the one-handed paddle design seen on competitors, it does make accidentally engaging the self-propulsion a little too easy. Usually this isn’t an issue, but often the moments when you’re grasping to get a better grip on the handle are the times you least want to engage the self-propulsion. For example, if you are mowing across a hill, there’s a brief moment during a turnaround when the mower is pointing up or down the hill. When adjusting your grip to make those turns, you may inadvertently tap the throttle, destabilizing your stance or your grip on the mower. If anyone from Ego’s reading this, they’ll probably say we’re mowing on too steep a hill, but hey, sometimes life throws a steep hill at you.
We think that the hour or so of run time is going to be enough for anyone keeping to about a half-acre, but if that’s not enough, additional batteries are available to extend run time infinitely. But batteries are costly. Depending on the Ah, they currently range in price from about 140 (2.5 Ah) to about 250 (5.0 Ah), and up to about 450 for a 7.5 Ah battery. They all fit, and with a second one on the charger while one is on the mower, you can really minimize or eliminate downtime.
Because the Ego is cordless and loaded with electrical components, the company does not recommend using a hose to wash out the underside of the mowing dome. Instead, the mower needs to be put on its side and the dome wiped off or scraped clean, using a plastic scraper. Because there is no gas or oil to leak out, this process is much easier than with a gas mower.
Finally, Wirecutter writer Kit Dillon, who loves his Ego mower, uncovered an issue with an older version of our pick, where the wires for the self-propulsion function run up the handle to the operating switch. “The wiring is super thin and where the arm bends over itself over time this wire breaks,” he explained. “The annoying thing is the wire is so thin it will sometimes break inside the sheath, which makes it difficult to diagnose or even find what section to repair.” Because of the large number of YouTube videos devoted to the problem, it’s clear that this isn’t an isolated incident. We’re not sure if this problem happens with this current version of the mower, but looking through the customer feedback at Lowe’s, we found a number of people saying that their mower won’t start, which makes us think the issue persists in newer models.
