Best Electric Lawn Mowers of 2021

The age of modernity electric lawn mower arrived. No longer tied with a lanyard like their primitive predecessors, today’s battery-powered models are much more powerful than before – very important when trying to keep your court in fine fettle. That said, today’s drums mower options are available in a wide range of prices and capacities. I discovered during these tests that there is a huge variation in the performance of a battery powered lawn mower compared to how it is advertised, as well as in the performance of battery mowers compared to a corded electric lawn mower or a gasoline lawn mower.

It’s not just the raw performance that’s critical either. Before you splurge on any of these machines, you’ll also need to figure out what types of batteries they use. Some mowers use batteries that also power popular brands of home power tools. DeWalt, EGO, and Ryobi are good examples of this type of cross-compatibility. If you already own tools from one of these or similar brands, you may not have to spend more money on additional hardware.

Other factors, such as whether a mower is self-propelled, can also have a big impact. This is especially true for large, heavy machinery that you prefer not to move without assistance. If you are looking for a push electric lawn mower, you are in luck. I have put together a bunch of the most popular electric mowers I could find here. I limited myself to push-from-behind models, which cost between $ 250 and $ 550. I then unpacked, assembled and personally put each unit to the test. Once the grass clippings from my mowing settle in, these are my favorites.

Anyone who doubts that an electric mower can compete with the power of gasoline models has not used EGO. At 62.6 pounds, this machine is one of the biggest and heaviest in my test group. That said, the EGO Power Plus certainly had the most oomph. Whether cutting the grass or getting through a low brush, this mower worked like a tank. Where other lesser mowers stalled, it was just unstoppable.

Despite its weight, the EGO Power Plus was a cinch to drive around the yard. I found it to be fast and stable too. I also appreciated being able to engage its variable speed motor without having to turn the mower blade. Other notable features include a wide 21-inch cutting deck and a 56-volt battery that works with EGO’s entire line of garden power tools.

Just because a lawn mower isn’t self-propelled doesn’t mean it’s difficult to operate. For example, the Ryobi 16 inch One Plus HP 18 volt push mower. Even though it’s extremely compact and weighs only 34.5 pounds, this little machine packs a punch. It stalled less than some of the larger, more powerful mowers in my test group, and the Ryobi’s light weight allowed me to push easily.

This machine also uses Ryobi’s standard 18-volt rechargeable batteries. These are the same lithium-ion power supplies the company uses in its popular line of household power tools. The mower comes with two batteries and a charger in case you don’t have one sitting around.

Its 16-inch cutting width, however, is on the narrow side. Still, for those with smaller yards (a quarter of an acre or less), the surprising power of this mower will suit their needs perfectly.

While the Hart Cordless 40 Volt Cordless Mower doesn’t have the raw cutting power of other electric push machines, it doesn’t lag behind either. The blades on this mower never stalled in my attempts to cut. He was also fed by a tough low brush without choking.

Despite a wide 20-inch cutting width, the 52-pound machine was relatively light. It is not self-propelled, so pushing the mower up is a challenge. Still, the mower’s low price and solid performance make it appealing to budget buyers. The pair of 40-volt batteries and charger are compatible with Hart’s line of power tools to sweeten the deal.

Other mowers I have tested


The Dewalt 21.5 in. 20 volts MAX.

Dewalt 21.5-inch 20V MAX Lithium-Ion Walk Behind Lawn Mower

I had high hopes for this Dewalt mower because of its large size, steel frame, and Dewalt’s long history of making power tools. Unfortunately, on the pitch, his performances were disappointing. The Dewalt 21.5 in. 20 volts MAX often stalls due to clippings getting stuck between the mower blade and the frame wall. The mower’s relatively high price tag of $ 500 adds insult to injury.

Ryobi 21 inch 40V brushless self-propelled mower.

Ryobi 21 inch 40V brushless, self-propelled

Close to the EGO mower in terms of power, speed and cutting capacity, the Ryobi 21-inch mower handled our test lawn well. He slowed down a few times, but recovered quickly and didn’t stall once. At the same price of $ 549, the more powerful EGO is the best buy.


Kobalt 40-Volt Max 20-inch Cordless Electric Brushless Lawn Mower.

Chris Monroe / CNET

Kobalt 40-Volt Max Brushless 20-inch 5 Ah Cordless Electric Lawn Mower

Lightweight for its size, this 56-pound mower is not self-propelled, but it was easy to push. Unfortunately, its underside clogged a few times during our testing. Its battery also requires some force to snap into place inside the mower’s socket.

Greenworks G-MAX 40V 16 inch cordless lawn mower.

Chris Monroe / CNET

Greenworks G-MAX 40V 16-inch Cordless Lawn Mower with 4 Ah Battery

Compact and lightweight, this model from Greenworks performed well. It didn’t stall during my trial mows and it was easy to push on the lawn. However, the battery holder inside the mower is on the top inner edge of its socket. This makes it more difficult to insert compared to other machines.

Sun Joe 24V-X2-17LM 48 volt 17 inch walk-behind lawn mower.

Chris Monroe / CNET

Sun Joe 24V-X2-17LM 48-volt 17-inch walk-behind lawn mower

This Sun Joe model can be light and easy to push. If you walk too fast, the mower can get stuck in the cut grass. You should also slide the machine batteries into their sockets at an angle that is not as intuitive as it should be.

Test the mowers

To test each lawn mower, I selected a flat area of ​​grass in the lawn of the CNET smart home. With all mower batteries fully charged, I set each mower’s cutting height to its # 4 position (higher number means higher cutting height). Then I used each machine to mow at least four full rows (15 feet) of lawn in both directions, with 180 degree turns between each row.

Some mowers like the Kobalt here can get stuck in cut grass.

Brian Bennett / CNET

I was very careful about whether the mowers stalled, got stuck, or struggled in any way while cutting. I also performed the same test on a low brush section on the outside edge of the lawn. This served as a torture test for high horsepower models and a good way to determine which mowers are really worth your money.
