I know the feeling: Saturday morning, gas can in hand, a pull cord that refuses to cooperate. Modern cordless power lawn mowers have made that ritual almost obsolete, and the current lineup genuinely covers everything from postage-stamp courtyards to a quarter acre of thick fescue. After comparing decks, battery systems, and real-world runtime across seven models, I put together a shortlist that should help narrow the field fast.
An Overview Of The Picks
Greenworks 80V 21in Push Lawn Mower
Casince 17in Cordless Walk-Behind Mower
Worx 20V 14in Cordless Lawn Mower WG733.1
Worx 40V 14in Cordless Lawn Mower WG735
Worx 40V 17in Cordless Lawn Mower WG745
EGO POWER+ 21in Self-Propelled LM2135SP
Litheli 40V 16in Cordless Lawn Mower
More On The Choices That Made The List
The Greenworks 80V sits at the top of this roundup because it strikes a balance most shoppers actually want: a 21-inch steel deck that handles real grass without feeling like pushing a wheelbarrow, and an 80V brushless motor that keeps noise low and torque high. The included 4.0Ah battery charges in roughly 60 minutes and stretches to about 60 minutes of cutting in typical conditions, which is enough for most lots under a half acre.
Single-lever height adjustment makes switching from a tidy lawn to taller summer grass a one-hand job. Owners coming from a gas mower typically notice the lack of exhaust and the easier starts on chilly weekends.
What Pays Off
- 21-inch steel deck covers ground quickly, so a typical suburban lot finishes in fewer passes
- Brushless motor (a motor with no internal brushes, which means less friction and longer life) delivers strong torque for thick grass with quieter operation
- Up to about 60 minutes of runtime per charge covers most medium yards without a battery swap
- Rapid charger refills the 4.0Ah battery in roughly an hour, useful for back-to-back sessions
- Single-lever height change keeps adjustments quick and consistent across all four wheels
Trade Offs To Consider
- At roughly 60 minutes of runtime, larger half-acre lots may need a second battery for uninterrupted mowing
- The 21-inch deck adds weight that may feel noticeable on slopes
- Steel deck construction can show scratches and should be dried after wet cuts to reduce surface wear over time
Feature Snapshot
Who Will Love This
Homeowners with a quarter to half acre of mixed grass who want one cordless mower that handles thick patches without sounding like a small engine.
Consider Something Else When
Shoppers with steeper terrain should look at the EGO POWER+ 21in Self-Propelled LM2135SP, since its drive system handles slopes with far less leg work.
The Casince 17-inch lands in the sweet spot for anyone mowing under 5,400 square feet of lawn. Two included 20V 4.0Ah batteries run in sequence and stretch mowing sessions to roughly 40 minutes, which is more than enough for courtyards, side yards, and small suburban lots. The 17-inch deck trims a path a step wider than compact 14-inch models without becoming unwieldy around flower beds.
Six height settings between 1 and 3 inches give plenty of seasonal flexibility, from cool spring growth to summer heat stress where taller cutting helps roots stay shaded.
The Good Stuff
- Two 20V batteries deliver sequential runtime up to about 40 minutes without a manual swap
- 17-inch deck balances wide coverage with easier storage than a 21-inch model
- Six height settings from 1 to 3 inches suit seasonal changes and varied grass types
- Plastic deck keeps weight low, helpful for older shoppers or those storing on a porch
Points To Note
- Plastic deck construction may dent or scuff if stored against sharp garden tools
- Runtime shrinks in thick or wet grass, so larger overgrown lots may need extra battery planning
At A Glance
Best Suited To
First-time cordless buyers with a small or medium lawn who want a wider cut than a compact model without paying for a premium deck.
Look Elsewhere When
Shoppers needing to cover a quarter acre or more with fewer passes should look at the Worx 40V 17in Cordless Lawn Mower WG745, which pairs a similar deck with stronger dual-battery output.
The Worx WG733.1 is the smallest, lightest model in the Worx lineup, and that is the entire point. A 14-inch cutting deck slips through narrow side yards, between raised beds, and around tight corners where a 21-inch mower feels like parking a truck in a garage. The 20V 5.0Ah PowerShare battery covers up to about 3,200 square feet per charge, which lines up with most urban lots under a tenth of an acre.
The brushless motor runs cool and quiet, and the 2-in-1 design lets you bag clippings or mulch them back into the lawn for a natural fertilizer boost.
Where It Helps
- Compact 14-inch deck maneuvers through gates and tight side yards that block wider mowers
- Lightweight build reduces fatigue during long weekend sessions
- 2-in-1 mulch or bag setup adapts to seasonal lawn goals
- PowerShare battery works across 140-plus Worx tools, helpful for anyone already in that ecosystem
Room For Improvement
- A 14-inch deck means more passes on larger lots, which can feel tedious past 2,500 square feet
- Single 20V battery limits continuous runtime and may require a swap on bigger jobs
Right Fit For
Urban and townhome owners with a postage-stamp lawn who care more about easy storage and quick cuts than wide-deck efficiency.
Swap It Out When
Anyone with a more open yard of about 5,000 square feet should consider the Casince 17in Cordless Walk-Behind Mower, which doubles down on dual batteries for fewer interruptions.
Where the smaller Worx 20V WG733.1 keeps things simple, the WG735 adds the kind of smarts that matter once the grass gets serious. IntelliCut technology automatically increases torque when the motor senses thicker growth, so a spring rush of rain-fed lawn doesn’t stall mid-pass. The 40V PowerShare platform runs cooler than lower-voltage packs and keeps brushless operation smooth.
The deck uses optimized airflow to lift grass upright before the blade cuts, producing a cleaner stripe than typical 14-inch mowers. Owners mowing up to roughly a tenth of an acre should find a single charge covers the full job.
Useful Touches
- IntelliCut torque sensing handles thick or patchy grass without manual speed adjustments
- Airflow-optimized deck lifts grass for a cleaner cut in fewer passes
- 40V PowerShare battery compatibility expands to other Worx outdoor tools
- Brushless motor runs quieter and lasts longer than brushed designs
Honest Caveats
- A 14-inch deck still means more passes on anything beyond a small lot
- Smart torque features shine in dense growth, but heavy wet grass can still reduce runtime noticeably
Feature Rundown
Made For
Homeowners with up to roughly an eighth of an acre who deal with mixed grass thickness and want a compact mower that adapts on the fly.
Not Your Match When
Shoppers needing wider coverage for bigger lots should look at the Worx 40V 17in Cordless Lawn Mower WG745, which steps up to a 17-inch deck for fewer passes.
The Worx WG745 is the bridge model for anyone stepping up from a small-yard mower to something that handles a real quarter acre. Two 20V 4.0Ah PowerShare batteries feed a 40V brushless motor, and the included dual charger refills both packs at once. The 17-inch deck cuts a wider path than the WG735 while staying easier to store than a 21-inch machine, making it a strong middle-ground pick.
Battery compatibility with 140-plus Worx tools means the same packs can run trimmers, blowers, and chainsaws, which simplifies a whole shed of gear over time.
Noteworthy Benefits
- Two 20V batteries power a 40V brushless motor for stronger torque in thicker grass
- Dual-port charger refills both batteries at once, useful between weekend sessions
- 17-inch deck handles up to a quarter acre with fewer passes than a 14-inch model
- PowerShare battery compatibility across the Worx ecosystem reduces charger clutter
Some Limits To Know
- No self-propel drive means pushing on slopes can wear out a leg before the mower does
- At a quarter acre, runtime can run thin in peak growing season, so a third battery is worth budgeting for
Quick Facts
Perfect Match For
Homeowners with up to a quarter acre who want premium runtime and a wider deck without jumping to a self-propelled model.
Where A Sibling Pick Shines
Anyone mowing on noticeable slopes should consider the EGO POWER+ 21in Self-Propelled LM2135SP, which adds drive assistance that the WG745 lacks.
The EGO POWER+ LM2135SP is the only self-propelled model in this lineup, and that single feature changes the experience on any yard with a slope or a long stretch. A 56V 7.5Ah battery drives the 21-inch deck and the rear wheels, while the Select Cut multi-blade system swaps among mulching, high-lift bagging, and extended runtime blades depending on the day’s goal. The included extra 5.0Ah battery extends sessions for larger properties.
This is the model that feels closest to a gas mower in capability, with none of the pull-start hassle. It is also the heaviest in the roundup, which is part of why the self-propel drive matters.
What Works In Its Favor
- Self-propelled drive takes the leg work out of slopes and long passes
- Select Cut multi-blade system adapts the cut to mulching, bagging, or longer runtime
- 56V battery platform delivers up to about 7.0 ft-lbs of cutting torque, comparable to many gas models
- Extra 5.0Ah battery extends sessions for larger or thicker properties
Practical Considerations
- Heavier than push mowers, so storage in a small shed may require planning
- Premium price tier compared to other picks in this roundup
- Self-propel drive adds a learning curve for anyone used to a basic push mower
Details At A Glance
Who Should Grab It
Homeowners with sloped lots or larger yards who want gas-like performance with simpler starts and zero fuel costs.
Skip It When
Shoppers with flat, compact lawns under 3,000 square feet will likely be happier with the lighter Worx 20V 14in Cordless Lawn Mower WG733.1, which is far easier to store.
The Litheli 40V mower closes out this list as a quietly capable suburban option. Both 5.0Ah batteries must be inserted to deliver the full 40V output, which keeps power steady even as the charge drops. The 16-inch deck sits between compact and full-size, and six cutting heights between 25 and 75 mm handle everything from a low spring cut to a tall summer setting.
A 50-liter collection bag means fewer stops to empty, and the mulching option lets clippings feed back into the lawn for a healthier root zone.
The Helpful Details
- 40V dual-battery system delivers consistent power that does not fade mid-mow
- Six cutting heights between 25 and 75 mm suit varied grass types and seasonal changes
- 50L collection bag reduces empty stops during longer sessions
- Brushless motor removes oil changes, spark plugs, and carburetor cleaning from the maintenance list
Where It May Fall Short
- Both batteries must be inserted for operation, so a single dead pack stops the whole mower
- A 16-inch deck is wider than 14-inch models but narrower than full 21-inch options, leaving it in an awkward middle for some shoppers
Built With In Mind
Suburban homeowners with a moderate yard who want consistent cutting height flexibility and a generous collection bag for weekly mowings.
Another Choice May Suit
Anyone needing stronger airflow for bagging wet clippings should look at the Worx 40V 17in Cordless Lawn Mower WG745, which pairs a wider deck with similar dual-battery architecture.
What Matters Most When Picking Cordless Power Lawn Mowers
Deck size sets the pace for any mowing session. A 14-inch deck moves easily through gates and around beds but requires more passes, while a 21-inch deck finishes faster but feels heavier and harder to store. Most homeowners do well with a 17-inch model that balances coverage and maneuverability, especially when paired with the right battery setup.
Battery voltage matter more than people expect. A 20V system handles small lots fine, but a 40V or higher platform keeps torque steady in thick spring growth. Amp-hour (Ah) ratings tell you how long the battery lasts, so a 4.0Ah pack will run longer than a 2.0Ah pack at the same voltage. For yards above a quarter acre, dual-battery designs extend runtime without forcing a mid-mow swap.
Self-propel drive is worth considering on sloped or long lots. Push mowers work fine on flat ground, but slopes tire out a leg before the battery does. The EGO POWER+ in this list is the only self-propelled model, which is also why it lands in the premium tier.
Cut height range and adjustment style affect how a mower adapts across seasons. Look for at least five positions, ideally adjustable from a single lever rather than four separate wheels. Mulching and bagging options give flexibility for thicker spring cuts versus tidy summer appearances.
Key Considerations Across These Picks
Where Shoppers Go Wrong
The most common slip is sizing a mower to the yard today, not next year’s needs. Grass fills in, lots get expanded, and a small-yard mower starts feeling tedious fast. Another trap is ignoring battery ecosystem compatibility, since brands like Worx let one battery power a trimmer, blower, and mower, which simplifies charging.
The Upgrade Payoff
Higher-tier mowers tend to add self-propel drive, multi-blade cutting systems, and larger batteries that stretch runtime. The Greenworks 80V and EGO POWER+ in this list carry those upgrades, and they tend to matter most on bigger lots or uneven ground. For flat small yards, the upgrade is rarely worth the higher price, but for a quarter acre with slopes, the comfort gain shows up every weekend.
Frequently Asked Questions
How long does a cordless lawn mower battery typically last?
Most cordless mower batteries deliver between 30 and 60 minutes of runtime per charge, depending on the voltage, amp-hour rating, and grass thickness. Higher-voltage systems with larger Ah packs tend to stretch closer to the longer end of that range.
Are brushless motors worth the upgrade?
Brushless motors run quieter, produce more torque, and last longer than brushed designs because they have fewer moving parts that wear out. For most homeowners, the upgrade is worth it if the budget allows.
Can a cordless mower handle thick or wet grass?
Modern 40V and 80V platforms can handle thick grass reasonably well, though wet grass reduces runtime and may clog the deck. Letting the lawn dry before mowing produces the cleanest cut.
How much yard can a 21-inch mower realistically cover?
A 21-inch deck finishes a quarter acre faster than a smaller model, but actual coverage depends on battery size, grass thickness, and walking pace. Most 21-inch mowers comfortably handle up to a half acre on a single charge.
Is self-propel drive necessary for a small yard?
Self-propel drive is rarely necessary on flat lots under a quarter acre. Once slopes enter the picture or the yard stretches beyond a half acre, the drive system noticeably reduces fatigue.
Closing Remarks
The right mower really comes down to yard size, slope, and how much runtime you want between charges. For most suburban homeowners, a 17-inch deck with a 40V dual-battery platform is the easiest place to start, and the picks above should cover almost any realistic scenario. Match the mower to your lawn rather than the other way around, and the Saturday morning routine gets a lot more pleasant.
