Getting the Best Cordless Lawnmower Means More than Voltage
The first thing we noticed about all our cordless lawnmowers was the number of different voltages. 36V, 40V, 56V, 80V, 120V batteries….How in the world are you supposed to pick the best cordless lawnmower with all those choices? We got our team together to look at the most important aspects of performance, features, and value to help you decide which cordless models did the best, which could handle the biggest lawns, and which ones were simply a great value.
We didn’t just compare our 17 cordless lawnmowers against each other, we also brought in 7 gas models. This let us not only see how the best cordless mowers did against their own class but also understand how close these models competed against gas mowers. If that’s your interest, check out the best gas lawn mower results.
We’re going to give you the winners first, but we realize you may prioritize some aspects over others. Be sure to check out how we tested each category, where each cordless lawnmower finished in them, and their overall final rankings and scores. You might even come to different conclusions than we did.
Best Cordless Lawnmower: Self-Propelled Mowers
Kobalt 80V Self-Propelled Lawn Mower (KMP6080-06)
Based on our testing, the best battery-powered self-propelled lawn mower is the Kobalt 80V model KMP6080-06. As the results came in from our testing, Kobalt’s 80V self-propelled mower didn’t find itself at the top of any specific test. But it simply refused to score poorly in ANY of them. Its consistently high performance in the categories that mattered the most, pushed it above its competition, making it the best battery-powered lawn mower we tested.
Greenworks Commercial 82V Self-Propelled Lawn Mower (GMS250)
Greenworks Commercial went with a dual-blade 25″ deck with a more stout design than most of the battery-powered mowers we tested. And though it struggled to keep its blades cutting in overgrown grass, like Kobalt, it scored very high in most categories. Its major hiccup would be price—which moves it away from the residential price range—gearing it more towards its target: professional users. That’s the price you pay for the higher build quality we saw in this tool.
Best Cordless Lawnmower: Push Mowers
Makita 18V X2 (36V) LXT Lawn Mower (XML03PT1)
Sometimes you either don’t want a self-propelled model, or manufacturers don’t offer it. The best battery-powered push model was the Makita 18V X2 Lawn Mower—model XML03PT1. Makita put together a solid mower and packs the kit with four 5Ah batteries. That gives it a massive advantage in the amount of area you can cut without having to buy more packs. Better yet, its dual-port Rapid Optimum Charger gets two batteries fully charged in just 45 minutes. It’s actually fast enough that, if you have access to power, you can cycle your four batteries all day long without waiting on the charger.
Stihl 36V Lawn Mower (RMA 510 US)
The Runner Up in the battery push mower class was the Stihl 36V Lawn Mower—model RMA 510 US. Stihl’s RMA 510 sets a high bar that only Makita was able to eclipse. It too didn’t outright win any category we tested. Rather, they took the runner-up category by consistently finishing well—similar to the Kobalt 80V mower. If all that sounds good, but you really want a self-propelled mower, Stihl should be delivering that model to dealers later this year.
Best Cordless Lawnmower for Large Lawns
Greenworks Commercial 82V Self-Propelled Lawn Mower (GMS250)
If you want the best battery-powered lawn mower for large lawns, that has to be the Greenworks Commercial 82V Self-Propelled Lawn Mower (GMS250). With just one battery, Greenworks Commercial cuts more area on a single charge than any other battery-powered lawn mower we tested. Its 0.85 acres has some competition from EGO, Kobalt, and Makita before leaving a large gap to the rest of the field.
EGO 56V Peak Power Self-Propelled Lawn Mower (LM2140SP)
The clear runner up in this category was the EGO 56V Peak Power Self-Propelled Lawn Mower (LM2140SP). Using the two 5.0Ah batteries that come in the kit, EGO’s dual-port Peak Power mower cut just 0.03 acres less than Greenworks Commercial. Need more? A pair of 7.5Ah batteries should net you close to 1.25 acres of mowing.
Most Powerful Cordless Lawnmower
EGO Peak Power Self-Propelled Lawn Mower (LM2140SP)
The most powerful cordless lawnmower in our real-world cutting test was again the EGO Peak Power Self-Propelled Lawn Mower (LM2140SP). In a rather torturous cutting scenario, we let Florida Bahai grow for around 5 weeks with on-and-off summer rains. Then we ran our top self-propelled mowers through it at normalized speed settings to see who could mow the furthest. EGO’s Peak Power system crushed the competition, including all but one gas mower!
Proof Load Testing
Redback 120V Self-Propelled Lawn Mower (1077479)
Our Proof Load Testing set each mower into a simulated difficult cut scenario. For battery-powered mowers, this ramped up the RPMs. The Redback 120V Self-Propelled Lawn Mower (1077479) was unmatched. No mower, battery or gas, put up the blade tip speed that Redback’s 120V model did under a heavy load. It’s the only mower we saw top 200 miles per hour!
EGO 56V Self-Propelled Lawn Mower (LM2100SP)
The Runner Up in this test was the EGO 56V Self-Propelled Lawn Mower (LM2100SP). EGO’s single-battery model actually increased its RPMs more than Redback but topped out just 0.6 short of 200 MPH under a heavy load.
Quietest Cordless Lawnmower
Worx 2 x 20V WG751
Noise levels matter and the Quietest Cordless Lawnmower was the Worx 2x20V WG751. Worx put on a show of how to reduce noise, producing just 74 no-load decibels. The next closest? 3 dB higher, and that’s going to feel about 33% louder to your ears.
Best Cordless Lawnmower Value
Greenworks Pro 60V Self-Propelled Mower (MO60L01)
The best value in a cordless lawnmower goes to the Greenworks Pro 60V Self-Propelled Mower (MO60L01). Having reviewed most of Greenworks products, their 60V line is often our favorite for a variety of reasons. With a $399 price tag for the kit, their self-propelled mower does most everything well—and that’s enough to edge out Kobalt’s 40V self-propelled model for the best value.

Tested Batteries and Kit Packages
One thing that became apparent immediately was the vast differences in battery packs and available power each of these mowers has. And truly, a lot of our tests boil down to the battery or batteries that come in the kit. Many of the brands offer different size batteries that you can use to extend your cutting capacity beyond what we tested. Also, remember that “Max” voltages drop by around 10% to their nominal voltages shortly after use. Here are the batteries that came in the kits we tested and their effective Watt-hour capacities—think of that like their filled fuel tank size:
- Craftsman 60V: 1 x 7.5Ah (405 Wh)
- EGO 56V Single Battery: 1 x 7.5Ah (420 Wh)
- EGO 56V Dual Battery: 2 x 5.0Ah (560 Wh)
- Greenworks Commercial 82V: 1 x 5Ah (369 Wh)
- Greenworks 60V: 1 x 5Ah (270 Wh)
- Kobalt 40V: 1 x 5Ah (172 Wh)
- Kobalt 80V: 1 x 6Ah (432 Wh)
- Redback 120V: 1 x 3Ah (324 Wh)
- Ryobi 40V RY40LM10-Y: 1 x 6Ah (216Wh)

- Snapper 82V: 2 x 2Ah (288Wh)
- Black & Decker: 2 x 2Ah (270 Wh)
- Echo 58V: 1 x 4Ah (204 Wh)
- Makita 36V: 4 x 5.0Ah (360 Wh)
- Redback 40V: 2 x 4Ah (288 Wh)
- Stihl 36V: 1 x 6.3Ah (227 Wh)
- Worx 40V: 2 x 5Ah (180Wh)
Best Cordless Lawnmower Cutting Area
We’re talking batteries because run-time is a big deal with battery-powered lawnmowers. The batteries take so long to charge back up. They’re not like an 18V power tool that’s ready to go after a 30-minute lunch break.
We determined the run-time for each mower—I’ll get to how in just a second. We then used those runtime numbers to get the total area you can cut based on the diameter of the blade. Make sense? You’ve got the cutting width and how long you can cut for. Keep in mind that the area figures are ideal numbers. Most of us will lose 5% – 10% because we need to overlap our lines slightly to avoid any mow-hawks (get it?).
Before we could calculate runtime, we needed a way to put a consistent load on each mower because grass is way too inconsistent to make a fair test. So we did some real-world mowing using a Greenworks 60V mower to find the actual real-world run-time doing a maintenance cut in grass. You know, just a little off the top. It turns out you get roughly 75% of your no-load runtime—that’s the runtime if you zip tie the handle and elevate the mower off the ground so the wheels can spin while the blade cuts through the air. On that mower, for example, it ran for 61 minutes with no load and actually cut for 46 minutes in our yard.
We proof-tested multiple sizes of steel tabs welded perpendicular to the back of the blade on each end to create air resistance. Eventually, we found that a pair of 1″ x 1/2″ steel tabs gave us 47 minutes of runtime with our baseline mower. That pretty much matched our real-world run-time number, so we were good to go.
We ran each mower under no load and then with the steel tabs to establish their respective runtimes and how they change compared to no load. For the self-propelled mowers, we used a photo-tachometer to set each drive to 2.5 MPH based on RPM and wheel diameter.
The more efficient mowers lost 15% – 20% of their no-load runtimes while the least efficient dropped more than 30%.
For straight-up runtime on a maintenance cut, no one gives you more runtime than EGO’s Peak Power model, hitting 96 minutes with its two 5.0Ah batteries. Kobalt’s 80V (91 minutes) runs just over an hour and a half and Greenworks Commercial comes close at 85 minutes. Craftsman (at 61 minutes) is the only other battery-powered model to give you more than an hour.
For the push mowers, Worx has the longest maintenance load runtime at 57 minutes followed by Makita at 51, both using two 90 Wh batteries for power. But Makita packs 4 batteries in their kit, giving you 102 minutes overall. Black and Decker also has an extra battery, moving it up to 62 minutes and ahead of Worx.
With the runtime and blade diameter numbers in hand, we calculated how much area each mower could cut at 2.5 MPH on the batteries that come with each kit.
Greenworks Commercial (0.85 acres) edges out EGO’s Peak Power mower (0.82 acres) by a hair with Kobalt’s 80V (0.77 acres) not far behind—all eclipsing 3/4 of an acre.
You’ll have to work harder to maintain 2.5 MPH with a push mower. If you can keep up the pace, Makita’s four-battery kit lets you cut up to 0.77 acres. Redback’s 40V model (0.52 acres) gets a little more done than Black & Decker (0.50 acres) in a distant second and third.
Using the information we learned from this test, here’s the max size lot size we’d recommend with the battery (or batteries) that come with each kit. These are full lot recommendations including the house, landscaping, and driveway. You can always cut larger lawns if you buy additional packs.
- Craftsman 60V: 1/2 acre
- EGO 56V Single Battery: 1/2-acre
- EGO 56V Dual Battery: 3/4 acre
- Greenworks Commercial 82V: 3/4 acre
- Greenworks 60V: 1/3 acre
- Kobalt 40V: 1/4 acre
- Kobalt 80V: 3/4 acre
- Redback 120V: 1/4 acre
- Ryobi 40V RY40LM10-Y: 1/4 acre
- Ryobi 40V RY40LM30: 1/3 acre
- Snapper 82V: 2 x 2Ah 1/2 acre
- Black & Decker: 1/2 acre
- Echo 58V: 1/3 acre
- Makita 36V: 3/4 acre
- Redback 40V: 1/2 acre
- Stihl 36V: 1/3 acre
- Worx 40V: 1/2 acre
Best Cordless Lawnmower Cutting Power
Blade speed tells us how well each mower handles a maintenance load and a heavy load. We started with the no-load RPM of each blade and used it and the blade diameter to calculate the tip speed. We repeated the measurements with 1/2-inch tabs to simulate our maintenance cut—and again with 2-inch tabs to simulate a heavy load.
This is Just the Tip (Speed) of the Iceberg
One of the advantages we see with brushless motors and their electronics is the ability to increase RPMs under a heavy load. Even some of the brushed models have sensors to trigger additional power. That increases the tip speed and lift of the blade to effectively deal with the tougher cut.
That extra power increase comes at a cost, though. Mimicking real-world conditions, our 2″ tabs cut our baseline mower’s runtime to roughly 1/3 of its no-load. If you’ve ever tried cutting tall, wet grass, 1/3 of the runtime is a pretty good estimate of what you get.
On a maintenance load, Craftsman (188.5 MPH) keeps its tip speed the highest, closing in on 190 MPH. Ryobi’s RY40LM10-Y (177.2) is more than 10 MPH behind and Greenworks 60V (172.5 MPH) drops almost another 5 MPH from there.
The push mowers don’t fare much better with Echo (176.8 MPH) leading the pack, followed by Stihl (167.8 MPH). There’s a significant drop off from there.
Things get interesting when the going gets tough. Redback’s 120V puts the speed on, lifting its blade tips to 200.5 MPH, followed closely by EGO’s single-battery model at 199.4 MPH. While a few others get close, none of the other self-propelled models hit 190 MPH.
Stihl (191.7 MPH) is the only push mower to exceed 190 MPH, though Echo makes it a competitive race at 187.6 MPH. Makita (171.1 MPH) sits in a distant third before the rest drop off.
What’s interesting here is that even though brushless motors (and some brushed motors with additional electronics) have the ability to increase speed, not every battery-powered lawn mower we tested did. EGO’s LM2100SP increased an impressive 33.7 MPH and Redback pulled an extra 29.6 MPH of effort.
On the other hand, Ryobi’s RY40LM10-Y dropped 7.2 MPH and Craftsman lost 24.4 MPH.
The real winner is in the push mowers with Makita, calling on an extra 37.4 MPH under a heavy load. Not wanting to be left behind, Stihl did a fine job with a 23.8 MPH increase.
Bonus: Real-World Torture Test
We let a section of grass grow for five weeks in the Florida rains without mowing and took our top contenders out to see what they could under the worst possible conditions. The grass was more than 8″ tall in most areas and we forced them through at 2.5 MPH. When the blades quit, we measured the distance. Here’s how the results shook out:
- EGO Peak Power: 60.5′
- Greenworks Commercial: 37′ (it did more pushing the grass than cutting it on the back of that measurement)
- Kobalt 80V: 36′
- Makita: 30.5′
- Stihl: 30.5′
- Craftsman: 21.5′
- Ryobi RY40LM30: 20.5′
- Snapper 82V: 18′
Not only did EGO put a huge gap on the entire battery-powered competition, but it also mowed farther than all of our gas mowers except a $1,200 Honda!
Note: Because we could not control the density of the grass and didn’t test every mower in it, these results were not used in the final scoring. They’re still pretty dang telling, though!
Best Cordless Lawnmower Battery Efficiency
Battery efficiency isn’t nearly as important as the amount of grass you can cut on a charge. However, it is helpful to see who is getting the most out of their watt-hours if you’re deciding what size battery to add when you want more cutting area.
By comparing based on watt-hours, it eliminates the volts vs amp hours discussion and breaks it down fairly no matter what voltage the motor is.
Minutes per Watt-Hour
We’ve broken it down two different ways to show you what to expect on a weekly maintenance cut. Basically, here’s how long in minutes you can run the mower for every watt-hour of battery capacity you have.
Like the cutting area, we’re also taking things a step further to show you the cutting area you get for every watt-hour assuming a 2.5 MPH pace (square feet/Wh).
These numbers represent what you can expect from a maintenance cut and start to drop drastically when you let the grass grow more than a couple of inches.
Greenworks Commercial is your leader from the self-propelled mowers. At 0.23 minutes per watt-hour, it edges out Ryobi’s RY40LM30 (0.22 min/Wh) and Kobalt’s 80V (0.21 min/Wh).
Not having to drive the wheels seems to be a benefit for the push mowers. Worx leads that group with 0.32 min/Wh, followed by Makita (0.28 min/Wh) and Redback’s 40V (0.24/Wh).
Square-Feet per Watt-Hour
Similar to how much you can mow on an entire battery, we also wanted a picture of how much our self-propelled mowers can cut for every watt-hour assuming a 2.5 MPH pace. We expressed this as square feet per Watt-hour.
These numbers represent what you can expect from a maintenance cut. Expect these numbers to drop significantly when you let the grass grow more than a couple of inches.
The more relevant measurement of cutting area per watt-hour brings into account the cutting swath of each mower. Greenworks Commercial takes its leading min/Wh and 23-1/4″ cutting swath to give it a big lead with 100 square feet of cutting for every watt-hour. Kobalt’s 80V and Ryobi’s RY40LM30 share second place with 77 square feet per watt-hour.
The push mowers show their advantage again with Worx leading all battery-powered mowers at 110 square feet per watt-hour. Makita (94 sq. ft./Wh) makes a strong showing as well. Once again, the two push mowers with a 2 x 18V/20V Max battery configuration are on top of systems that have more watt-hours at their disposal.
Best Cordless Lawnmower Noise Level
One of the major benefits of cordless mowers is the lower noise levels compared to gas. We expected lower noise and several models made it under 80 decibels.
To test the noise level, we used our SPL meter and checked the sound on a road away from any houses. With Tom Gaige as our “standard” user (he’s 5’8″), we measured the decibels as A-weighted, slow response from his ear. The shorthand for that measurement is “dB(A) SPL” but we’ll just use “decibels” for short.
This test shows how much sound the mowers produce on their own. When you’re cutting grass, the numbers will be a little higher, particularly when you hit thick grass. Often the motor drives more power to compensate.
Snapper (78 decibels) and Greenworks 60V (78 decibels) lead the way with Greenworks Commercial (79 decibels) and Kobalt 40V (79 decibels) wrapping up the sub-80 group for self-propelled.
The only real surprise and concern occurred with Redback’s 120V mower. It hit 88 decibels putting it 2 decibels higher than Honda’s gas mower.
Push mowers dipped a bit lower with Worx producing just 74 decibels while Makita and Redback hit 77.
Best Cordless Lawnmower Feature Set
By far the biggest feature on a cordless lawnmower is a self-propelled drive. It pretty much neutralizes any weight concerns other than getting it home from the store or off your trailer.
But that’s not all there is. Here’s a list of what we looked for, why it’s important, and who has it.
In general, steel decks are more durable than plastic but make a heavier mower. We prefer a steel deck, especially on a self-propelled mower that doesn’t have an effort penalty for the extra weight.
- Craftsman 60V: Steel
- EGO 56V: Plastic
- EGO 56V Peak Power: Plastic
- Greenworks Commercial 82V: Steel
- Greenworks 60V: Steel
- Kobalt 40V: Steel
- Kobalt 80V: Steel
- Redback 120V: Steel
- Ryobi 40V RY40LM10-Y: Steel
- Ryobi 40V RY40LM30: Plastic
- Snapper 82V: Steel
- Black & Decker: Plastic
- Echo 58V: Plastic
- Makita 36V: Steel
- Redback 40V: Steel
- Stihl 36V: Steel
- Worx 40V: Steel
Single Point Height Adjustment
Single-point height adjustment means you can adjust all four wheels at one time. It makes adjustments easier, but the reality is that most of us will set it once and change it very little over the course of the lawn mower’s life.
The downside is that for some cordless lawn mowers, single-point height adjustments introduce extra flex that’s not there on four-point adjustments. It’s one of the reasons you see commercial gas lawn mowers stick with a four-point design.
- Craftsman 60V: 1-point
- EGO 56V: 1-point
- EGO 56V Peak Power: 1-point
- Greenworks Commercial 82V: 1-point
- Greenworks 60V: 1-point
- Kobalt 40V: 1-point
- Kobalt 80V: 1-point
- Redback 120V: 1-point
- Ryobi 40V RY40LM10-Y: 1-point
- Ryobi 40V RY40LM30: 1-point
- Snapper 82V: 1-point
- Black & Decker: 1-point
- Echo 58V: 4-point
- Makita 36V: 1-point
- Redback 40V: 1-point
- Stihl 36V: 1-point
- Worx 40V: 1-point
Height Adjustment Range
All of these cordless mowers have the height range to cover most grass species. However, there are some (like St. Augustine here in Florida) that you can reasonably cut 3-1/2″ or higher for the healthiest lawn.
While there’s no baseline here, check to make sure the mower you’re looking at cuts the height you need. Greenworks 60V and Makita both have maximum heights under 3-1/2″.
- Craftsman 60V: 2″ to 4″
- EGO 56V: 1-1/2″ to 4-1/4″
- EGO 56V Peak Power: 1-1/2″ to 4-1/4″
- Greenworks Commercial 82V: 1-1/2″ to 4″
- Greenworks 60V: 1″ to 3-1/4″
- Kobalt 40V: 1-1/4″ to 4-3/8″
- Kobalt 80V: 1-1/4″ to 4-3/8″
- Redback 120V: 1-3/4″ to 4-1/4″
- Ryobi 40V RY40LM10-Y: 1-3/8″ to 4-1/2″
- Ryobi 40V RY40LM30: 1-3/4″ to 4-1/2″
- Snapper 82V: 1-1/8″ to 4-1/8″
- Black & Decker: 1-1/4″ to 4″
- Echo 58V: 3/4″ to 4″
- Makita 36V: 1-1/8″ to 3-1/8″
- Redback 40V: 1-1/8″ to 3-5/8″
- Stihl 36V: 1-1/2″ to 4″
- Worx 40V: 1-1/2″ to 4-1/4″
Height Adjustment Levels
More height adjustment points mean more control from the smallest to largest heights. While there’s some variance in the group, none of these lawnmowers have too few points of adjustment.
- Craftsman 60V: 6 levels
- EGO 56V: 7 levels
- EGO 56V Peak Power: 7 levels
- Greenworks Commercial 82V: 7 levels
- Greenworks 60V: 7 levels
- Kobalt 40V: 7 levels
- Kobalt 80V: 7 levels
- Redback 120V: 7 levels
- Ryobi 40V RY40LM10-Y: 7 levels
- Ryobi 40V RY40LM30: 7 levels
- Snapper 82V: 7 levels
- Black & Decker: 7 levels
- Echo 58V: 7 levels
- Makita 36V: 10 levels
- Redback 40V: 7 levels
- Stihl 36V: 6 levels
- Worx 40V: 7 levels
Having two or three handle height positions give those of us that are really tall or short a better chance at finding a comfortable grip while mowing. Worx is the only model to give you just one handle position.
- Craftsman 60V: 3 positions
- EGO 56V: 3 positions
- EGO 56V Peak Power: 3 positions
- Greenworks Commercial 82V: 3 positions

- Redback 40V: 2 positions
- Stihl 36V: 2 positions
- Worx 40V: 1 position
Here in Central Florida, the vast majority of homeowners and Pros use the mulching function rather than bagging or side discharge. But that’s not the case across the entire country.
With cordless mowers gaining popularity in nearly every market area, it’s important that any mower has all three options. And every one of these battery-powered lawn mowers does.
With a gas engine, you have to store your mower on a relatively flat surface. That’s not the case with battery and all of the battery-powered lawn mowers we tested have the ability to fold up the handles and stand vertically to take up less space.
Waiting on a battery or two to charge kills your momentum when you’re trying to get the lawn cut. You’re better off having a spare set instead of mowing part of the lawn, waiting for a charge, and then starting up again. Some brands embrace that with chargers that take hours while others get you back in the game faster.
EGO includes a Rapid Charger in their kits and they lead the charging rate by a big margin. Their batteries have a higher capacity (420 and 280 Wh), so even though the charger is quick—they’re not the fastest to go through a full cycle. That award goes to Snapper who gets their 2Ah pack (144 Wh) back in the game in just 30 minutes, followed by Makita’s dual-port charger filling both 5.0Ah packs (180Wh) in 45 minutes.
Here’s the charging rate (watts) of each charger along with the estimated time it takes to get one included battery (two for Makita and Worx) fully charged so you can keep mowing.
- Craftsman 60V: 108 watts (3 hrs, 45 min each)
- EGO 56V: 420 watts (1 hr each)
- EGO 56V Peak Power: 420 watts (40 min each)
- Greenworks Commercial 82V: 295 watts (1 hr, 15 min each)

Additional Battery Bay
If you need to switch batteries, sometimes you have to stop and walk back to the garage or shop. Some cordless lawnmowers have an extra battery bay to let you store another pack onboard. Even better, a few have an active second port and some automatically switch over so you can mow for longer without interruption.

Best Cordless Lawnmower Value
If you’ve been around us long, you know value means a lot more to us than price. It’s what you get for the money. Better performance and a higher quality build cost more and every manufacturer is looking for the sweet spot. When they get the right combination, it’s worth paying a bit more for a product that fits your needs better.
For the way we graded value, the Greenworks 60V lawn mower led the self-propelled group. Kobalt’s 40V model was just a point behind and the Ryobi RY30LM03 led a group by a couple of points that included the single-battery EGO, Redback 120V, and Craftsman V60 mowers.
Worx easily leads value for the push mowers while Black and Decker scores high as well. Redback finishes off the podium finishers for that group.
Best Cordless Lawnmower Final Rankings
In addition to the ranking, we’ve included the overall score. We also list the category or categories in which the mower scored more than 90 points. Since you determine which features you care about the most, this should help you decide which one is the best battery-powered lawn mower for you.
Keep in mind that the mowers are only compared to the others in its class—self-propelled doesn’t directly compare to push.

Why You Should Consider a Cordless Lawnmower
The best cordless lawnmower for you gets your lawn cut on one charge. No matter which model that is, they all share some common characteristics. There are no gas emissions and no gas engine to maintain. You still need to clean it off when you’re done, but the maintenance is much easier and takes less time.
They’re also quieter. The early bird gets the worm and if you want to start mowing at 7:00 on Saturday morning, your neighbors can probably sleep through it. More of a night owl? Many battery-powered mowers have headlights and you’re unlikely to disturb your neighbor’s Lord of the Rings marathon at 10:00 PM.
Those are some of the more obvious reasons, but one of my favorites is the ability to put the battery in and mow. There’s no cranking, no choke, and no fuel cut-off valve. As long as you have enough batteries to get the entire lawn cut, it’s an easier system to work with than gas.
