Best Cordless Lawn Mowers of 2021: Whisper-Quiet Lawn Care

I picked up the Ryobi 40V Brushless Push Mower from Home Depot in the late summer of 2020 after completing an extensive landscape job in my backyard. After using the mower weekly for three months, I am impressed. This mower does not have any propulsion, so you have to push it yourself. And if you’re fit, that’s plenty easy as it weighs just 56 pounds. For a smaller lawn, there is no reason to get anything else, unless you are not comfortable with pushing a mower.

Thanks to the brushless motor design, there is less internal friction than many mowers. I found that the run time of 48 minutes on a charge was plenty for me to mow my lawn about four times between charges. With about an 800-square-foot lawn, that seemed about right on the money for the brand’s claims. The 20-inch mower even varies the power output depending on the resistance of the grass, so if it hits a thicker or taller section, it kicks into a turbo mode to keep the blades spinning fast. 

This mower is remarkably quiet. Even my dog, who’s scared of the vacuum, doesn’t mind it. It folds easily for storage (I carry it into my basement after each use). Overall, this is an excellent choice for a small, cordless electric lawnmower. Read the in-depth review here. 

If a small, light mower is all you need, the Greenworks 17-Inch 40V Cordless Lawn Mower is an ideal choice. Weighing in at just 36.2 pounds, it’s perfect for those who may need to lug it up or down stairs or store it in a small space. Users note that, even though small, this is an effective mower with both mulching and bagging capabilities.

This agile and lightweight cordless lawnmower offers an efficient 40V lithium battery system that has been coupled with specially hardened blades that offer optimal cutting results.

The Greenworks GLM801601 21-inch 80V Cordless Push Lawn Mower is one of the most powerful and impressive cordless lawn mowers on the market. Many cordless lawn mowers fall short on battery life. They might have a 30-minute run time but the battery takes two hours to charge, which means it’s difficult to finish the job. This lawnmower comes with two 80V 2AH batteries, each of which has a run time of around one hour and takes around 30 minutes to charge. That means you can charge one whilst using the other, so you can keep this lawnmower running all day if you need to. 

With a 21-inch cutting deck and similar performance to a gas-powered lawnmower with a 160cc engine, the Greenworks GLM801601 is ideal for any sized garden. It also benefits from Smart Cut Technology, a system that changes the speed of the blade depending on the resistance of the grass. Plus, it has a 3-In-1 grass collection design that allows you to mulch, rear bag, or side discharge your clippings.

Our premium selection for the very best cordless mower is Snapper’s mighty 82 Volt machine. It comes with two Briggs & Stratton 82-volt MAX lithium-ion batteries and a rapid charger to keep it juiced up to the max. It provides the rugged power of a gas mower, but without the need for refills and oil spills while also being lightweight and easy to handle.

This self-propelled cordless lawn mower does the hard work for you as you take a stroll around the yard. The Snapper XD mows as it goes using smart load sensing technology. The 21-Inch steel mowing deck with a 3-in-1 design allows you to choose whether to mulch, bag, or side-discharge grass clippings. Sure, it’s on the pricey side, but if you have a larger or hilly lawn, this is the tool for the job.

The Tacklife Cordless Lawn Mower is one of our favorites on the market. While Tacklife is a lesser-known brand, this model brings a lot of value. Powered by a 40V max 4Ah battery (KB4040A), it runs for about 30 minutes on full power. This should be enough time for most small to medium-size yards. You can purchase extra batteries for this model if you need more juice. Plus, it only takes a couple of hours to charge back up. 

The lightweight design and 16-inch cutting deck make it easy to maneuver, even if your yard isn’t level. If you’re used to a gas-powered lawnmower, this one will seem like a breeze. We also like the fact that it’s completely foldable. You can adjust the handle to three different heights. Fold it down completely to save space in your garage or shed. The other main selling point is the fact that it collects 98% of the grass clippings if you want to bag them. 

The WORX WG779 is a reliable and relatively powerful cordless lawnmower. It’s not the most powerful lawnmower on this list and it doesn’t have the longest battery life, but it has a few key benefits that might make it the lawnmower for you. Firstly, it has space for two 20V Power-Share batteries, which are included with the mower. That allows it to cut around 5,500 square feet on a single charge. Plus, if you own any other WORX 20V tool, the batteries are interchangeable. We also like the fact that the handle is padded with foam to make it comfortable. If you’ve ever used a gas-powered lawnmower with a metal handle, you know how quickly your hands go numb. It’s designed for small gardens and has a 14-inch cutting deck and lightweight body to make it easy to move around.

This Greenworks Twin Force cordless electric lawn mower is an excellent solution for keeping on top of smaller lawns and its battery ensures that you get the job finished every time. It is lightweight and compact making it comfortable to maneuver without relying on a cord, and easy to store when not in use.

The dual mower blades are strong enough to deal with thick grass without putting too much pressure on the battery life and its Smart Cut technology will identify just how much power is needed for a sufficient mowing job. The push button start is another great feature that totally eliminates those strenuous memories of yanking the pull-chain just to get your older mowers started.

A small electric lawnmower has 6 different height settings and can contend with most grass types that it encounters. The new lithium-ion batteries provide 33% increased power on a single charge when compared to previous models.

BLACK+DECKER built this model to tackle even the most uneven yards in the neighborhood and has no issues conquering hilly, weedy areas. And if you have other BLACK+DECKER tools, this is a solid choice as it uses the same batteries as its suite of lawn-care products. And while most consumers note good durability with this 16-inch mower, some claim to have damaged it while pulling it backward. As it has a lower consumer rating than other models on this list, we’d only recommend it for those who already have this brand’s other tools and want to streamline battery use. Also, this makes a great gift for gardeners in your life.

This mower is simply a beautiful piece of machinery that will make you wish it was summer all the time, and might even consider moving somewhere that is a reality, just so you have an excuse to use it as often as possible. To prepare your lawn for mowing, use one of the leaf blowers from our list.

With two batteries, the DEWALT battery mower is tough, tight, and powerful enough to tackle the most overgrown areas. Dewalt builds great tools, and this is no exception.
