With more lawn mower models on the market than ever before, and so many sizes, styles and features to consider, making buying a lawn mower isn’t as simple as it once was. And now, electric mowers are making a big splash in the lawn care industry.

Not long ago, mower motors required too much juice for a cord or batteries to be practical. Not anymore. Modern refinements and innovations allowed corded and battery-powered electric lawn mowers to burst onto the scene with gusto.

Gas-powered mowers ignite a mixture of air and fuel, compressing it in a cylinder, then igniting it with a spark to create a miniature explosion which is harnessed to power the machine. Electric mower motors, however, feature magnets interacting with electromagnets, energizing metal coils to move rotors and create power. Electric mowers can be powered by batteries or a 120-volt receptacle via extension cord.

Lawn Mower Considerations

Motor Power

Lawn mower manufacturers can be disingenuous about the real world power levels of their products. It’s not uncommon for electric mowers, for example, to have their “max torque” specs touted as evidence they match gas-burning models in power output. This is deceptive.

Max torque gives an inflated perspective of a mower’s true power because it measures engine torque under little or no load. The fact is, horsepower is the only reasonable unit of measure for lawn mowers, which I suspect is why electric lawn mower manufacturers don’t share this figure. The real-world horsepower of most electric mowers is half, or less than half, the horsepower of a similarly sized gas-powered machine.

Run Time

It’s hard to measure exactly how much run time you’ll get from a tank of gas in your average fuel-burning mower, because much depends on the speed you run it and the density of the grass you’re cutting. It’s a safe bet, though, that a tank of gas will last longer than a fully charged battery on any equivalent electric model.

Most electric mower manufacturers give a maximum run time estimate, which for push and self-propelled mowers is almost always an hour or less. Riding electric mowers might run two hours, tops, on a single charge. Plug-in mowers don’t require batteries and will keep running continuously unless there’s a power outage. In that case, a generator with sufficient voltage capacity can keep you going.

The Environment and Noise

While power and run time certainly favor gas-powered mowers, noise and environmental considerations support electric. Battery-powered mowers have zero carbon emissions, so running one won’t contribute to climate change. Even the best gas-powered mowers can give off a significant amount of emissions.

Noise is also a factor worth considering. Many municipalities regulate the acceptable amount of yard noise. Big, beefy gas-powered mowers can easily exceed these guidelines, but battery-powered mowers almost certainly won’t.

Note: Some users find vibration is more severe and bothersome with gas burning mowers than electric.

Laws and Regulations

In some states, the laws will dictate which mowers you can and can’t buy. California passed a law in 2021 banning the sale of gas-powered lawn equipment. That will take effect as soon as 2024. However, to help ease this transition, California has set aside 30 million for a rebate program to offset the cost of new zero-emission equipment for professional gardeners and landscapers.

Manufacturers are starting to follow suit. John Deere unveiled its very first electric riding mower in 2023, with additional models to come. Honda announced in 2022 that it will stop making gas-powered mowers all together.

Operating and Maintenance Costs

Although it’s tempting to believe battery-powered mowers will always cost less than gas-burning mowers long-term, this isn’t necessarily the case. Although you’ll almost certainly spend less on electricity charging your batteries or running your corded mower then on gas and lawn mower oil for your fuel-burning machine, there’s more to the equation.

Lithium ion batteries don’t last forever and eventually need replacement. They’re not cheap, either. If your electric mower comes with a generous warranty, you might be lucky enough to get a replacement battery (or batteries, if your mower takes two) for free when yours bites the dust. Otherwise, you could be looking at a 200 to 400 expense.

Ease of Use

Electric mowers are usually simpler to use and maintain than their gas-powered counterparts. They don’t need gas, oil changes or new air filters, and you don’t have to make sure the carburetor and spark plugs are clean and functional.

How To Choose the Right Mower

Battery-powered mowers work best for people with small lots who want to minimize maintenance, noise and carbon emissions. But if noise and exhaust don’t bother you, and you just want to mow and be done with it as quickly as possible, you’re probably better off going gas-powered.

Whether you go with gas or electric, it’s important to choose the right model for your needs. If you’ve got an acre or less to mow, a self-propelled walk-behind mower is probably your best bet. If you’ve got a larger lawn or simply don’t like walking and mowing at the same time, a riding mower will make your life much easier.

detailed considerations like engine power, blade speed, deck width and other features come down to personal preference and available budget.

What to Look For in an Electric Lawn Mower

Let’s be honest there are some things in life that we buy because we feel we should, not necessarily because we need them. Hi-tech, high-powered devices are often seen as must haves, over just as serviceable but more humble equivalents. Lawn mowers are no different, with many people rushing out to buy a petrol mower when an electric one will do just fine. Besides this, electric mowers actually have many distinct advantages over petrol mowers, but if you’re unsure about the advantages and disadvantages of electric mowers compared to petrol mowers then do take a minute to read the advice at the bottom of our homepage on whether to choose Electric or Petrol to get further information.

Electric lawn mowers have existed for many years as the middle ground between the more powerful petrol powered mower, and the laborious manual lawn mower. They are favoured by many consumers for their cost effectiveness, a simplistic design that doesn’t demand a great deal of maintenance, and their compact and light weight nature, making them ideal for use by the young and old alike, and those with only limited storage space.

Due to their limited size and power limitations, it’s quite normal to require other tools in combination with an electric lawn mower, such as grass trimmers and edging tools, to help with particularly tough and hard to reach areas that are beyond the reach of the lawn mower blade. However petrol lawn mowers also suffer from the same limitations in many cases.

The best electric lawn mowers will address all the limiting factors in terms of size, weight, power, and overall performance to provide a well rounded solution that suits your needs perfectly. Of course, what suits you and what suits the next person’s needs will differ on any number of factors, but making the choice to go with an electric mower is of course the first step.

So if you know that you’re firmly in the electric camp then let’s continue on and see what features to look out for when buying the best electric lawn mower to suit your needs.

Useful, But Not Completely Essential Features

Worth careful consideration, but not going to be the difference between being able to cut the lawn or not:

  • Cutting height adjustment – Again not as necessary for smaller lawns, but you’ll need this feature if you aim to do more than just keep your lawn cut short on a regular basis. If you’ve got uneven or overgrown areas then you’ll need to be able to set the cutting height up high, and if you want to crop the lawn shorter then you’ll need to be able to set it lower. Most wheeled rotary mowers come with a simple means of adjustment to do this, but you might find it more of a task with a cylinder or hover mower.
  • Battery power – There is no denying the improved freedom that not having a cord trailing behind you will provide, but this comes at a price, normally 4 times the price to be exact. Also bear in mind that you’ll have the increased weight of a battery on board to contend with, this takes away the normally great benefit of electric mowers being at least half the weight of their petrol counterparts. For more detailed information check out our guide to the best cordless lawn mowers.
  • Ergonomic controls – It’s definitely a massive help to maintain comfort and ease of operation for all sorts of reasons, but if your lawn is really quite small indeed then this is probably an area that you can afford to skimp on.
  • Warranty Support – No one ever plans for the worst to happen, but it can be reassuring to know that help is at hand if it does. If your lawn mower breaks then you’ll need to get it sorted or else your lawn will grow out of control! Check carefully what each manufacturer can offer, most will offer some level of support, but others are better at it than others, with full on-line support showing service centre locations, and detailed trouble shooting information, whereas others only have an email or phone number which might not always deliver the most timely response.

Electric Lawn Mower Reviews

So, armed with your overview of knowledge on electric lawn mowers the next step is to look in a bit more detail at some of the best examples on the market today where you can take a view on which is the best electric mower for you.

Bosch Advanced Rotak 650 Lawn Mower

A highly rated and proven machine from one of the most trusted names in consumer products and electricals, this Bosch electric lawn mower features just the right combination of innovative features and cost effective, sensible design suitable for use by the fair weather gardener.

This mower features an innovative ‘ergoflex’ handle design that makes it comfortable for use by just about every size and shape of person. If you prefer to grip a handle with both hands facing up, or you are more inclined towards an upright ‘joystick’ type grip, then this mower is able to accommodate both thanks not only to both types of handle being present, but with ‘dead mans’ levers in all positions. Given this is the main point of interface between you and the mower it makes good sense that a great deal of time and effort has gone into designing it, and the good news is that it works really well, which should (fingers crossed) take some of the pain out of the task of mowing the lawn, which can only be a good thing I’m sure you’ll agree…

Black Decker BEMW471BH Lawn Mower

If you’re after a modern electric lawn mower that’s packed full of innovative features to make your life easier then look no further than this great product from Black and Decker.

With so many great features it’s difficult to know where to start with this but we’ll give it a go! Perhaps one of the most clever and useful features of this design is the grass collection box. Working on the age-old problem of trying to reduce the amount of times the grass box must be emptied during a mowing session, the solution here is in the form of a compressive mechanism that you operate with a foot pedal as and when you feel the box is getting too full, this compacts the grass and frees up space in the front of the box. When the box really is completely full and cannot be compacted any further you’ll see this is the case through the window located at the front…

Flymo SimpliGlide Hover Lawn Mower

If you’ve read our introductory page you’ll see that we’ve dismissed most hover type mowers as ineffective due to their integral grass box making the payload of the mower variable, which therefore reduces the ‘hover height’ of the mower and could leave it scraping along the ground rather than gliding effortlessly. This isn’t the case with hover mowers that don’t have an integral grass box (as is the case with this one), as no grass is collected the payload does not change.

Now that’s cleared up we need to determine whether a hover mower, regardless of whether it’s effective or not, is for you. Typically this type of hover mower is used on slopes and banks as it can be ‘swung’ by the operator in any direction, making it ideal when dealing with areas that are hard to walk on and would be even harder to walk on with a conventional mower. So if you have a particularly hilly or uneven garden this type of mower may have some merits, however if you plan to use it to mow decent, flat areas of lawn, it’s not going to be suitable given the mess of cut grass that it will spew out as it goes. So if you’re lucky enough to have large garden, and you can spare the expense, it would very useful to use this mower in conjunction with a conventional wheeled mower so that you’ve got all the tools you need to tackle every area…

Before You Buy an Electric Mower

Electric mowers are eco-friendly and a great choice for those who wish to forgo the fuel and oil required for gas-powered mowers. Still, an electric model might not be for everyone. The gas vs. electric mower debate rages on, with adherents on both sides making convincing points.

An electric mower can reduce the carbon footprint and is much quieter. In contrast, a gas-powered mower is loud but can run for hours, as long as a can of gasoline is nearby. It’s also usually more powerful, making it better suited to mowing thick, dense grass where an electric mower can get bogged down.

How We Tested the Best Electric Mowers

Our electric mower trials included assembling each machine according to the manufacturer’s directions. Battery charging times, where applicable, were checked against the times claimed in marketing. Then, we tested the mowers in an actual backyard setting, with all of the difficulties and flaws that might be expected in a yard, including slopes; uneven ground; dense grass with weedy patches; and tall, overgrown areas.

For consideration as a top pick, each mower had to perform at least as well as claimed in the brand’s marketing materials. Additionally, we considered aspects that a typical user may find most useful: durability, ease of operation, user comfort, required storage space, price, and performance under high-strain (but not abnormally so) conditions.

All of our cordless picks were capable of operating similarly to gasoline-powered counterparts in terms of cutting power in thick, weedy, and tall grass. They were able to easily maintain manicured lawns and perform at least a limited amount of rough cutting in overgrown areas. The corded picks proved capable of producing a clean finish on currently maintained areas, with or without weeds, but were only cursorily tried in taller grass. The robot mower was programmed and used only on a maintained area with few weeds, but the ground did include a significantly sloped area.

Our Top Picks

The following picks highlight some of the best electric mower options. Read the individual reviews for details on how each one performed in our backyard tests.

Greenworks Pro 80V 21 Brushless Cordless Lawn Mower

This Greenworks electric mower comes with two 80V G-MAX lithium-ion batteries that are also compatible with other G-MAX-powered lawn tools. It runs on one battery at a time and will power through nearly an acre of the lawn during the 60 minutes of runtime provided by a full charge.

We liked the push-button starting system that is conveniently located near the grip for easy operation. Also, the lack of drive motors for the wheels saves weight and extends battery life compared to the self-propelled models we tested. Even on sloped areas and rough ground, it was easy to push and maneuver. Overall, it gave a more “gas-like” mowing experience than any of the others, albeit without self-propulsion.

This model boasts a generous 21-inch swath cut. It features the brand’s SmartCut technology, which senses when the grass becomes denser and speeds up the blades and earns this mower the best overall spot as one of the top-rated electric lawn mowers. The mower also provides a 3-in-1 system, allowing the user to choose between mulching, bagging, or discharging the grass clippings. Large 7-inch front wheels and 10-inch rear wheels make it easy to mow and maneuver.

  • Includes 2 batteries
  • Easy push-start button
  • Sensor to adjust blade speed for thick grass
  • Not self-propelled
  • Limited battery life
  • Side discharge chute fits loosely and could be knocked off

Sun Joe MJ401E-PRO Electric Lawn Mower

This Sun Joe pick is among the best corded electric mower options, with a 14-inch cutting swath and a rear-mount grass bag that catches clippings. It features a powerful 13-amp motor and optional rear-mounted side discharge chute. An adjustable cutting height from just over 1 inch to 2¼ inches makes it well suited to low-growing, warm-season grasses, such as Bermuda, zoysia, or centipede.

No need to store gasoline or change spark plugs with this plastic mower that is as eco-friendly as it gets. Collect grass clippings in a 10.6-gallon bag or discard them via a rear-mounted side discharge chute. The Sun Joe mower boasts a nonslip grip handle that folds down for easy storage. A 12- or 14-gauge exterior extension cord is necessary for operation (not included). Some assembly of both the handle and the wheels is required.

While this mower is heavier and includes a more powerful motor than the other corded mowers we tested, it lacks a few conveniences. The Sun Joe’s handle is fixed-mounted to the body for a more rigid feel. Also, all four wheels are equal size (5.5 inches in diameter), which made it a bit less maneuverable over rough ground and in tight spaces. That said, the stronger motor provided the best performance in dense grass. This model is a good choice for those on a budget who don’t mind putting in just a bit more effort.

Product Specs

  • Lowest price point among those we tested
  • Felt more durable than the other corded models
  • Good performance even on tough warm-season grasses
  • Compact size good for storage
  • Heavier than the other corded models we tested
  • Smaller wheels do not maneuver as easily
  • Handle does not adjust easily

Get the Sun Joe electric mower at Amazon, Lowe’s, Tractor Supply Co., or Overstock.

American Lawn Mower Company Corded Mower

The corded electric mower from American Lawn Mower Company offers convenient features at an attractive price point. It features an 11-amp motor and cuts a 14-inch swath width. The cutting height adjusts from 1 inch up to 2.5 inches, making it most suitable for low-growing and warm-season grass types.

This mower is a good choice for those with small yards and limited storage space. We liked the nonslip grip handle for comfortable control. The large 7-inch rear wheels and narrow, lightweight, compact body made it easy to pivot and navigate tight spaces. Plus it had no problem mowing thick, weedy grass. It did struggle with tall grass since the tallest setting is 2.5 inches, compared to 3-plus inches on the other mowers.

The mower also features a safety shutoff if the user releases the handle while mowing, and it folds down to aid in storage. You can set the mower for clippings to discharge into a 16-gallon grass bag or to fall back on the lawn for use as natural mulch. Users will need a 12- or 14-gauge exterior extension cord (not included) to run the mower.

Product Specs

  • Compact size that is easy to store; even in small spaces
  • Lightweight and easy to maneuver; great for extended use
  • Budget-friendly price compared to similar models
  • When bagger is nearly full, front wheels may lift off the ground
  • Bogs down in tall grass
  • Feels less durable than other corded models

Snapper XD 82V MAX Step Sense 21-Inch Mower Kit

For those looking for a powerful, high-end electric mower, this cordless model from Snapper doesn’t disappoint. One of the best battery-powered lawn mower options, it runs on a super-charged 82-volt lithium-ion battery; two batteries and the charger are included.

This mower cuts a generous 21-inch swath, rivaling some of its gas-powered competitors. Weighing in at a hefty 72 pounds, this mower is heavier than other electric mowers but features self-propulsion to lighten the load.

The mower features a push-button start and seven cutting heights, from 1⅜ inches to 3¾ inches, making it appropriate for most turf types. It offers large 10-inch rear wheels and a grass-catching bag that fits on the back, with clippings discharging to either the side or the back.

In our trials, this mower was a top performer in terms of power and overall user comfort. The step-sense feature, which increases or decreases the self-propelled pace, was most noticeable on slopes. It operates based on the push-pressure applied to the handle. As you push harder, the mower moves forward faster. At times the mower feels like it’s running away from you, until you get acclimated. We noted that the sliding handle mechanism has a slight tendency to “stick” instead of sliding (and changing the pace) smoothly.

Product Specs

  • Powerful motor can handle most lawn jobs
  • Self-propulsion feature automatically adjusts to user’s pace
  • Wide range of cutting heights (7 settings from 1⅜ to 3¾ inches)

EGO Power Self-Propelled Mower

Our best self-propelled choice could have also been tapped as a runner-up for the best overall choice. In addition to the convenience of powerful cordless operation, it offers feature upgrades typical of more expensive models. The 56V, 7AH battery offers up to an hour of runtime per charge and recharges within 60 minutes. The self-propelled feature simply adjusts to the right pace with a lever. Also, cutting power automatically increases when conditions get tougher, such as in dense weedy areas or tall grass.

EGO got it right on the basics, too. The oversize wheels roll smoothly over rough terrain and make for easy manual operation when not using the self-propelled feature. The handle easily adjusts for different user heights and folds up neatly for storage. Choose from rear bagging, side discharge, or mulching with the included equipment.

In our tests, the EGO Power mower was comfortable and easy to use in all conditions. We liked the simple speed adjustment for the self-propelled pace—a lever located on the left side of the handle—but the drive motor seems excessively noisy. importantly, the self-propelled feature cuts battery life in half, compared to using the mower in manual mode. At 83 pounds, this was one of the heavier mowers in the lineup. Since this mower only comes with one battery, buyers may want to consider adding a second battery for longer runtime and less wait time for charging.

Product Specs

  • Better overall performance than other cordless mowers at this price point
  • Easily adjustable self-propelled feature
  • Automatically increases cutting power in difficult conditions
  • Noisy drive system
  • Poor traction for slopes or wet grass
  • Self-propelled feature cuts battery runtime in half

Get the EGO Power cordless mower at Ace Hardware, Lowe’s, or Acme Tools.

Worx WR147 Landroid Robotic Mower

Save a ton of effort with this top-quality lawn robot. The Worx Landroid robot mower handles yards up to ¼ acre, thanks to a 20-volt motor and 2 hours of runtime. Plus, it only takes 90 minutes to reach full charge. Two brushless wheel motors offer extra traction, allowing this 23-pound mower to cut lawns with a 20-degree slope.

The Landroid’s 8-inch, triple-blade cutting disk mows close to the edges of a yard with adjustable height between 1.6 and 3.9 inches. Obstacles aren’t an issue with this robot mower; if it encounters them, the mower backs away, and you can also program it to exclude certain areas.

Although the Landroid requires more setup effort than a traditional mower, once it’s up and running, it is nearly 100 percent autonomous. To get started, we downloaded the app, installed the boundary wire and charging station, charged the mower, and programmed the mowing schedule. Total setup time was about 2 hours, but we allowed the battery to charge overnight prior to the first scheduled mowing.

We observed the mower in operation. Similarly to a robot vacuum, the Landroid mows in a random pattern, using its software to map out the most efficient route. It avoids obstacles by first bumping them, then rerouting (an “Anti-Collision System” is available as an add-on purchase). When the battery runs low, the Landroid returns to its docking station to recharge, then completes the program. An onboard rain sensor disrupts the mowing schedule as needed to avoid cutting wet grass.

This mower is ideal for those with up to ¼ acre of grass who like the idea of “set it and forget it.” It mowed fairly close to the edges, but a quick touch-up with a string trimmer will be necessary, maybe once a week during the summer. Other than that, it’s a matter of monitoring the app and observing the lawn. Blade changes will be required a few times during the season; the frequency depends on programming and the type of grass.

Product Specs

  • 2 hours of runtime; great for average-size yards
  • Mows on schedule, even when you’re out of town
  • Custom schedules and routes via the app
  • Expensive up-front cost
  • Requires a strong Wi-Fi signal and/or Bluetooth connectivity
  • Some occasional maintenance is required

Greenworks Corded Lawn Mower

With a 14-inch swath width powered by a 9-amp electric motor, this Greenworks corded electric mower makes quick work of cutting small to medium-size yards. The quiet-running mower features a push-button start and graduated wheel size, with 6-inch front wheels and 7-inch rear wheels, to make maneuvering the mower a snap. It features a safety handle that must be engaged when mowing; when the handle is released, the mower stops.

The grass-cutting height is adjustable from 1¼ inches to 3 inches, and the mower features both a 10-gallon rear bag for catching grass clippings and mulching capability. At the end of an afternoon’s work, the handle folds down for easy storage, allowing it to be stowed along a wall in a garage or storage shed. A 12- or 14-gauge exterior extension cord (not included) is required for operation.

With its 9-amp motor, this was not the most powerful corded mower we tested, but it proved capable of cutting down taller grass and did not struggle as we anticipated it would in dense, weedy areas. We liked the ergonomic design of the handle, but the squeeze-lever controller felt like it could be tiring for those with smaller hands or less hand strength. Also the handle attachment hardware, which is a unique lock-lever screw, appears to be intended as a convenience but works awkwardly. The locking lever does not close if the mechanism is threaded too tightly—a point at which the device still feels loose.

Product Specs

Electric VS Petrol Lawnmowers | The Gadget Show

  • Ergonomic handle for more comfort and less fatigue
  • Quieter operation than other corded models
  • Large wheels roll easily over rough ground
  • Least power of the corded models we tested
  • The screw-clamp handle adjustment knobs operate awkwardly
  • Squeeze-lever operation may not be comfortable for all users

Greenworks Brushless Push Lawn Mower

Boasting a 21-inch swath cut, this Greenworks cordless mower can operate for up to 70 minutes powered by its two 40-volt lithium-ion batteries (included), allowing users to mow longer without stopping to recharge. When one battery runs down, the power automatically switches to the second battery.

The mower features self-propulsion, large front and rear wheels for easy maneuvering, a push-button start, height adjustment from 1⅜ to 3¾ inches, and a folding handle for easy storage. Rear bagging, side discharge, and mulching options are all available to collect clippings. As a bonus, the battery charger includes a USB port that can charge a cell phone or tablet if necessary.

In our tests, this 40V mower compared favorably to the other cordless models with bigger batteries. It mowed at lower power until engaging a heavier load of dense or tall grass, then it automatically increased output for the tougher work. In mulching mode, thick grass tended to bog down the blade somewhat. The self-propel feature uses a pressure-sensitive sliding handle to automatically adjust to the user’s pace. Unfortunately, like the Snapper mower, the mechanism feels somewhat sticky at times so that the mower feels like it is jerking away. Still, overall this mower offers excellent runtime and performance in most conditions.

Product Specs

What to Consider When Choosing the Best Electric Mower

Electric mowers offer a variety of options that make them more suitable for certain lawns and users. Keep the following factors in mind when selecting the best electric lawn mower for maintaining your yard.


There are several types of electric mowers, including push, self-propelled, riding, and robot mowers. The most suitable type depends on your yard, budget, and the amount of labor you’re comfortable with.

  • Push lawn mowersare basic walk-behind models, requiring manual effort to move the mower forward. They’re significantly less expensive compared to other electric varieties, which contain more advanced features. Since push mowers require more labor, they’re ideal for small to medium-size yards with even ground.
  • Self-propelled lawn mowers propel the wheels forward while cutting grass. These mowers often cost several hundred dollars more than push mowers. The trade-off is convenience, and the reduced effort involved makes them preferable for medium-size to large lawns and sloped terrain.
  • Riding lawn mowers are as heavy duty as they come, with a high price tag to match. Multiple varieties fall under this mower category, including lawn tractors, zero-turn, and rear-engine mowers. Users operate the mower in a seated or standing position. Featuring the largest cutting width and terrain capabilities, they’re built to tackle large yards and navigate hills and even steep slopes with ease.
  • Robot lawn mowers function autonomously and require the least amount of effort. These high-tech models come with many modern features, like programmable mowing, collision sensors, and app operation. Lawn robots are less powerful compared to other mowers. They also have a shorter run time and a limited cutting width, so they’re not a top choice for large lawns.

Corded vs. Cordless

Many electric mowers today are cordless and run on rechargeable lithium-ion batteries. Reliable corded options still exist for push and self-propelled mowers. Each power source has its own benefits and downsides.

Battery-powered mowers can be taken anywhere a lawn needs cutting and offer the most flexibility. However, when the battery runs down, usually within 30 minutes to an hour, it requires recharging before mowing can be resumed. Investing in a second battery can double the operating time for cordless mowers since you can switch out the first one when it runs out.

The advantage of a corded electric mower is that an electrical outlet provides unlimited power. Corded mowers are often more affordable and weigh less due to the absence of expensive batteries. A definite drawback is that the user is limited to the extension cord’s length.

For those considering a corded mower, keep in mind it will require a heavy-duty extension cord; a 12-gauge or 14-gauge cord is best, although it’s always important to check the owner’s manual.

Motor Power

Lawn mower voltage, measured in volts (V), coincides with how much energy the motor can handle. The higher the voltage, the more energy is conveyed from the battery or power outlet to the motor. volts are necessary to mow large lawns and produce sufficient torque to cut through tall and thick grass. You can expect these voltage and coverage areas for electric lawn mowers:

  • Push mowers: 18V to 80V (¼ acre to 2 acres)
  • Self-propelled and riding mowers: 40V to 120V (¼ acre to 3 acres)
  • Riding mowers: 50V to 120V (½ acre to 3 acres)
  • Robot mowers: 18V to 40V (¼ acre to 1 acre)

It may seem logical to choose a mower based on battery voltage, but this figure alone does not reflect motor power. Amperage (amps) also determines how powerful the motor is. Amperage is the rate at which electrical current is delivered to the lawn mower, usually ranging from 2 to 12 amps.

The motor power of an electric lawn mower is determined by wattage (W), which equals volts multiplied by amps—so a larger battery doesn’t always result in a more powerful mower. For example, a 5-amp mower with a 60V battery (300W) is less powerful than a 7-amp mower with a 50V battery (350W).

Brushed vs. Brushless Motor

Brushless motors are more efficient, with minimal energy lost as heat. They produce less friction (which damages the motor) and are easier to maintain since there are no worn-out brushes to replace. All together, these factors translate into better performance compared to brushed motors.

By contrast, brushed motors produce more heat at the expense of power. Consequently, this type of motor may cause a mower to overheat and stall. While they’re more susceptible to friction and heating issues, with increased maintenance requirements, brushed motors are the most affordable option.

Deck Size and Swath Width

A lawn mower’s deck size is the width of its cutting swath. The wider the swath—the width of grass you can cut in a single pass—the fewer passes you’ll have to make. On the other hand, a wider swath requires more power, which can translate into shorter battery life.

The best electric push mower and self-propelled electric mower options have an average swath width from 13 to 22 inches, robot models are at 5 to 10 inches, and riding mowers can go up to 54 inches. If the lawn is small, even a 15-inch swath width will get the job done without taking too much time. Larger yards will benefit from a broader swath width so it doesn’t take forever to mow them.

Size and Weight

The size and weight of a mower are also important considerations, especially if storage and user strength are limited. Higher voltage mowers are generally heavier, simply because larger batteries weigh more. Additionally, mowers with a larger deck width tend to weigh more than smaller models.

Riding mowers are the largest, heaviest models out there. A small riding mower is comparable to a go-kart, while heavy-duty models resemble a “subcompact” car. They can weigh as little as 400 pounds to upward of 800 pounds.

Self-propelled mowers usually weigh more than push models since self-propulsion requires more battery power. These mowers generally range from as little as 30 pounds for a small push mower to upward of 100 pounds for a large self-propelled mower. Note that self-propelled mowing still involves some manual labor, such as navigating tight spaces and moving the mower backward (they only self-propel forward).

If you’re looking for a lightweight tool, go with a corded push or robot mower. Corded electric mowers are lighter than their cordless counterparts since there are no batteries to weigh them down. Most corded mowers can be easily hung on the wall of a garage or shed to save space.

Robot mowers are the smallest and lightest options, usually weighing between 15 pounds and 30 pounds. Most are only slightly larger than a robotic vacuum. For these reasons, they are incredibly portable and easy to store.


Push and self-propelled mowers built to take on uneven ground and thick grass have larger rear wheels with a diameter of 8 inches or more. Compact models with small wheels, on the other hand, are better at getting in and around flower beds and navigating around trees and other obstacles in the yard.

Riding lawn mowers have tires, with different types suitable for certain terrains. Lug tires are thick and designed for traction, so they’re the ideal choice for wet, slippery, or sloped yards. Smooth tires prevent ruts and other damage to manicured lawns. Turf tires establish a middle ground, with reasonable traction and less damaging effects on the yard.

Additional Features

The top electric lawn mowers and lawn-maintenance brands include convenient features and functions to look out for, which offer enhanced versatility and safer operation:

  • Speed control: Basic electric lawn mowers operate at only one speed, while others include multiple speed settings. Speed may be adjusted using a squeeze handle, dial, drive bar, or a pace-keeping system (usually reserved for high-end models).
  • Cutting height adjustability: Like gas models, most electric mowers can be adjusted to suit a variety of cutting heights, ranging from 1 to 4 inches. Before choosing a mower, find out the optimal cutting height for the grass. The general rule of thumb is to cut most grass types between 2 and 3¾ inches high.
  • Side or rear discharge: For users who want to collect the grass clippings, either to discard or add to a compost pile, look for a mower with a side or rear discharge and an attachable bag.
  • Mulching: Some lawn mowers contain mulching blades. Mulching mowers cut the grass into smaller pieces, which returns some of the nutrients to the lawn.
  • Safety: Most electric mowers have a safety bar built into the handle. The bar must be held closed to keep the motor running, minimizing the risk of accidents. Many also contain flaps and guards, which prevent the mower from discharging debris at the user.

Tips for Using Electric Mowers

Corded electric lawn mowers have been around for decades, but they didn’t have nearly the power to rival most gas-powered mowers until recently. Today’s models cut most turf with ease, but the following tips will help users achieve the best results and avoid mistakes while mowing.

  • Cut the lawn as often as needed to maintain optimal grass height without cutting away more than a third of each grass blade. This might mean having to mow every 3 or 4 days during the lawn’s fast-growing season, but by cutting no more than a third of the grass blade, the grass will be healthier and more resistant to diseases.
  • Mow away from the cord. Rather than starting at the outside of the yard and mowing back and forth toward the house, start near the electrical outlet and then mow in swaths progressively farther away. This helps keep the cord out of the way and reduces the risk of running over it.
  • Don’t use a corded electric mower on wet grass. Electricity and water don’t mix, and mowing wet grass can lead to an electrical short or danger of electrical shock.

The Advantages of Owning an Electric Lawn Mower

Electric mowers produce the same power as gas-powered options, so trimming your lawn is always fast and easy. Using an electric mower can help to reduce your ecological footprint while also providing versatile and easy-to-use features. Most electric models save you the hassle of replacing spark plugs and fuel filters, oil changes are no longer required, and there is no gas tank to consistently refill, making them eco-friendly and money-saving.

Exhaust fumes and pollution are also a thing of the past without the use of gas. Another convenient feature included in electric models is that they are far quieter than their gas-powered counterparts. Here are a few more benefits of owning an electric mower:

  • Less maintenance and fewer replacement parts required.
  • Electric mowers are light and easy to maneuver compared to gas-powered models.
  • Electric models are less expensive than gas-powered mowers.


electric mowers are on the market today than ever before, and they’re a more eco-friendly way to care for a lawn. For those new to this type of mower, read on to have a few of the most frequently asked questions answered, and check electric lawn mower reviews and manufacturers’ websites to learn more about the model you’re eyeing.

Q. Do electric mowers cut well?

In general, electric mowers are not as powerful as gas-powered mowers, but for average lawns where the grass isn’t ultradense, they usually work quite well.

Q. How long does an electric mower last?

Depending on quality, an electric mower should last between 5 and 10 years. A lithium-ion battery (for a cordless electric mower) should be replaced approximately every 5 years.

Q. How do you maintain an electric mower?

Store an electric mower in a garage or covered shed and clean any stuck-on grass clippings from under the mower deck before use. Sharpen or replace blades as needed. In comparison to gas mowers, electric mowers require very little maintenance.

Q. How often should I mow my lawn?

Weekly mowing is the general rule, but it varies, depending on the lawn and season. Slow-growing grass can be cut every 2 weeks, while manicured lawns may require mowing twice per week. Robot mowers are typically programmed to mow the lawn two or three times per week.

Q. Is it safe to cut wet grass with my electric mower?

It is not recommended to use an electric mower on wet grass. The moisture from wet grass can cause damage to the mower’s motor and can lead to your grass being cut poorly.

Q. Is it safe to leave my electric mower outside?

Electric mowers should be stored indoors when not in use. However, electric models can be stored outdoors if they are elevated and/or covered so they remain dry and air can circulate underneath the motor.

Q. Where should I keep my electric mower during the winter?

During the colder months, eclectic mowers should be stored in a dry, clean, and well-ventilated area to ensure no moisture reaches the motor. These models should also be kept in a place where they will not be exposed to corrosive materials or excessive heat.

Q. How do I clean my electric mower?

If excessive mud, dirt, or grass has caked your electric mower’s construction or undercarriage, it should be cleaned with a moist cloth or plastic brush. Do not use a pressure washer or hose, as these models cannot resist excessive amounts of water. When cleaning the undercarriage, the cutting blades should be removed as a safety precaution.

Q. Does an electric mower require oil to work?

No oil or petrol is required to ensure your electric lawn mower is running correctly.

Q. How do you properly recycle an old electric mower?

As electric mowers are classified as electrical waste instead of scrap metal, they should be disposed of in the same way household appliances should be recycled. If your electric mower has stopped functioning altogether, you can recycle it at a household electrical recycling facility.
