Why Choose Electric Over Gas + 5 Picks for the Best Electric Lawn Mower


Before You Buy an Electric Mower

Electric mowers are eco-friendly and well suited to homes without storage space for the fuel necessary to run gas 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 reduces the carbon footprint and is relatively quiet. 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 grasses where an electric mower can become clogged.

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 mowers are 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 labor, they’re ideal for small- to medium-sized yards with even ground.
  • Self-propelled lawn mowers, as the name implies, propel the wheels forward while cutting grass. These high-end mowers often cost several hundred dollars more than push mowers. The tradeoff is convenience, and the reduced effort involved makes them preferable for medium- to large-sized 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, 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 runtime and a limited cutting width, so they’re not a top choice for large lawns.

Corded vs. Cordless

Most electric mowers today are cordless and run on rechargeable lithium-ion batteries. Reliable corded options exist for push and self-propelled mowers, but they’re rare in comparison. 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 2 hours, 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 once it runs out.

The advantage of a corded electric mower is that an electrical outlet provides more reliable power. They’re often more affordable and weigh less due to the absence of batteries. A definite drawback is that the user is limited to the extension cord’s length, which is typically 50 to 100 feet long.

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. More 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: 18 volts to 80 volts (1/4 acre to 2 acres)
  • Self-propelled and riding mowers: 40 volts to 120 volts (1/4 acre to 3 acres)
  • Riding mowers: 50 volts to 120 volts (1/2 acre to 3 acres)
  • Robot mowers: 18 volts to 40 volts (1/4 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 6 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 average swath width of an electrical mower ranges from 13 to 22 inches for push and self-propelled mowers, 5 to 10 inches for robot models, and up to 54 inches for riding mowers. 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 upwards of 800 pounds.

Self-propelled mowers usually weigh more than push models, since self-propulsion requires more battery power. These mowers usually range from as little as 30 pounds for a small push mower to upwards 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, navigating around trees, and other obstacles in the yard.

Riding lawn mowers contain 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

There are some other features and functions to look out for in an electric mower, offering 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.
  • Rear roller: Lawn mowers with a real roller allow users to cut closer to the edges of property lines, garden beds, and other borders, eliminating the need for a trimmer.
  • 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.

  • Cut the lawn as often as needed to maintain optimal grass height without cutting away more than ⅓ of each grass blade. This might mean having to mow every three or four days during the lawn’s fast-growing season, but by cutting no more than ⅓ 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.
