Best Cordless Lawn Mowers of 2021: Whisper-Quiet Lawn Care
Battery lawn mowers are the way of the future. Just like electrification is sweeping into the automotive industry, so too it’s taking over smaller powered tools like lawnmowers, chainsaws, and more. For people in urban areas, and those with small to moderate-sized, well-managed lawns, the best cordless mowers now make more sense than ever.
As spring rolls around and people are dusting off their mowers for the summer, now’s a good time to consider switching to electricity. There are many benefits to electric mowers — you don’t need to store or stabilize gas, no oil needed, and they’re downright quiet!
Further, electric mowers are vastly superior to old-school gas mowers in terms of emissions. According to the U.S. Environmental Protection Agency (EPA), a new gas-powered lawn mower produces volatile organic compounds and nitrogen oxides emissions air pollution in one hour of operation as 11 new cars each being driven for 1 hour! The emissions from old gas-powered mowers are so bad that some areas, like Colorado’s Front Range, offer cash incentives ($150 in Colorado) for turning in your old mower in exchange for a new cordless lawnmower.
But which one to buy? Well, we first researched the best cordless electric lawnmowers on the market, pouring over reviews and data about lawnmowers. Then, we tested our top choice on our own lawn for 3 months (so far). And we’ve been impressed with the performance. Our research is currently ongoing, and we expect more test results by late spring 2021. But for now, we’re really loving the Ryobi 40V Brushless Push Mower (full review here). If you just want a good mower for a small lawn without self-propulsion, it’s our top choice.

The Best Cordless Lawn Mower Review
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.

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.

Cordless Lawn Mower Buying Guide and FAQs

Features To Look For In Cordless Lawn Mowers
It would be unwise to assume that all cordless lawnmowers would perform at the same level of operation. There are a few features to tick off the list before purchasing the desired lawnmower.
Battery: The battery is the heart of the cordless lawnmower. It has to have the capacity to run long enough to cover the expanse of your lawn or field. Depending on the type of grass, it may take more power to smoothly lower the grass. So the battery capacity is important so it runs powerfully even on terrains that require more power.
While some older lawn mowers used lead-acid batteries, almost all modern battery-operated mowers use lithium-ion batteries, which offer great power in a lightweight package. Most of these will range from 20 to 80 volts, and from 2 to 8 amp-hours. To figure out how much power the battery has — quantified as wattage — you have to multiply volts times amp-hours. Our top selection here, the Ryobi 40V 20-inch mower, has a 40V, 6.0 ah battery. That means it packs 240 watts of electricity, enough in this case to mow a half-acre of grass!
Performance: A good lawn mower should be able to clear and level grass without hassle. A top-performing lawn mower will offer adequate clearance and efficiency while taming an overgrown lawn.
Deck Size: The deck size is essentially the radius of the cutting deck. So a 20-inch mower will be, you guessed it, 20 inches wide. A wider mower will make faster work of a lawn job. But it will usually weigh more and be larger to store.
Mower Size & Weight: Cordless lawn mowers are relatively larger and heavier than corded electric mowers; this is obviously because of the battery. However, they tend to be rather small and light compared with gas mowers. Small lawn mowers are appropriate for smaller sized lawns; they wouldn’t work efficiently enough on larger field’s cause of the time factor
Self-Propelling: Some lawn mowers are self-propelling; they have a motor that pushes the machine along leaving you to steer it in the required direction. This provides a more hassle-free mowing process, taking away the manual pressure of pushing the machine yourself.
Extras: Some lawn mowers will come with extra devices that help to keep the charger optimally charged. This may include an additional battery or a charging unit.
Budget: Cordless lawn mowers would probably cost from $260 to 4 digit figures. It’s important to consider how much you’re willing to spend on a good lawn mower before going ahead to purchase one.
Types of Lawn Mowers
Mulching Cordless Lawn Mower: Mulching lawnmowers put the grass back in the soil after trimming it. This is done by sharp blades and a mulch plug that cuts the grass into bits and places it back in the soil. This is extremely beneficial for the lawn since the trimmed grass delivers nutrients to the soil and makes it quite healthy. The regrown grass will come back looking greener and better.
Collecting Cordless Lawn Mower: These types of lawnmowers have a bag or box that takes in the trimmed grass. This saves you time and energy of raking or collecting the trimmings yourself.
Dual-purpose Battery Lawn Mower: Fortunately, most mowers these days give you the option of either bagging your grass trimmings or mulching them, with the same mower. You do this usually by switching the bag for a plug that fills the hole the bagger would normally cover. Not every mower does this, but for those who want the option of mulching in the summer, and then using the bagger to pick up leaves in the fall, this is a very nice feature.
Corded vs. Cordless Electric Lawn Mowers
Corded Electric mowers need to be connected to a power source to run. They are generally more powerful and will run as long as you need them. It may, however, limit your movements and the cords may get tangled while mowing. The plus side is these mowers may cost less than the cordless ones.
Cordless lawn mowers are battery-operated; this means they have a limited time to run. The run time will generally last long enough to complete the task at hand. However, they are a bit heavier than electric corded mowers and are more expensive.
Cordless Lawn Mower FAQ

A: The blades and mower deck should be cleaned regularly. The battery also needs to be optimally charged, but take care not to over-charge it in order to sustain the battery's performance and lifespan.
