Cordless mowers have quietly outgrown their “starter tool” reputation. The latest 40V and 56V platforms now deliver real torque, self-propelled drive, and finishes that rival mid-tier gas models, all without the pull cord, the oil, or the Saturday tune-up. That shift matters for anyone tired of feeding a small engine, and it’s the reason this list leans almost entirely on battery power.
I focused on six walk-behind cordless mowers that map cleanly to different yard sizes, from a 14″ ultra-light for a tight side yard to a 21″ self-propelled machine for half an acre or more. Each pick below earns its spot for a specific reason, and the buying guide that follows covers the trade-offs I weighed so the choice feels easier.
The Lineup, Simplified
Greenworks 80V 21in Push Lawn Mower, 4.0 Ah Battery and Charger
Worx 20V 14″ 2-in-1 Cordless Lawn Mower (WG733.1)
Worx 40V 14″ 2-in-1 Cordless Lawn Mower (WG735)
Worx 40V 17″ 2-in-1 Cordless Lawn Mower (WG745)
EGO POWER+ 21″ Self-Propelled Mower (LM2135SP) Bundle
Litheli 40V 16″ Cordless Lawn Mower with 2×5.0Ah Batteries
A Closer Look At Each Pick
The Greenworks 80V platform borrows muscle from the brand’s pro line, and the 21″ deck here is the widest in this roundup, which means fewer passes across an open yard. A brushless motor, meaning a design with no internal brushes to wear down, gives it the kind of quiet operation and longevity that used to require a gas engine. The single-lever height adjustment lets one person swap cutting heights in a single motion rather than fiddling at each wheel.
It ships with an 80V 4.0Ah battery and a rapid charger, and a full charge reportedly returns in around an hour. Runtime scales with grass conditions, so thicker, wetter growth eats into that 60-minute claim.
Noteworthy Benefits
- The 21″ steel deck covers more ground per pass than the 14″ picks below, trimming mow time on wider lawns.
- The 80V system runs cooler and quieter than a comparable gas mower, which neighbors tend to appreciate on early weekend mornings.
- Single-lever height adjustment is faster than per-wheel setups, especially when switching between driveways and grass.
- The brushless motor typically outlasts brushed designs, which matters for anyone mowing weekly through the season.
Things To Consider
- It is a push mower, so steeper slopes demand more legwork than a self-propelled model like the EGO POWER+ LM2135SP.
- Steel decks tend to weigh more than composite ones, and storage in a tight shed corner can get awkward.
- Cold-weather runtime on any 80V pack tends to dip, so spring starts in northern climates may finish a touch short.
Built With In Mind
Homeowners with a flat to gently rolling mid-size yard who want a wider deck and quieter operation than a gas mower offers.
Look Elsewhere When
Anyone with a sloped lot will find the EGO POWER+ LM2135SP a more comfortable match thanks to its self-propelled drive.
The Worx WG733.1 is the smallest, lightest cordless mower I considered, and that is genuinely the point. Its 14″ deck and 20V platform target people with a postage-stamp side yard, a fenced rental, or a townhouse patch where anything bigger is overkill. Pushing it around raised beds and narrow gates feels less like mowing and more like steering a broom.
It shares the PowerShare battery platform with the larger Worx models further down this list, so the same 20V pack can run trimmers and blowers. A 2-in-1 deck handles bagging or rear discharge.
Strengths Worth Knowing
- At well under 30 pounds, it is easy to carry up stoop stairs or hang on a wall hook in a small shed.
- The 20V 5.0Ah PowerShare battery covers roughly 3,200 sq. ft. per charge, which is plenty for a city lot.
- Sharing batteries across the Worx 20V lineup cuts clutter if you already own a trimmer or blower.
Worth Noting
- A 14″ deck means more passes on anything past a small yard, and a quarter-acre lot will feel like a long walk.
- Lightweight builds can struggle in tall, wet grass where a heavier mower with more torque, like the Worx WG735, simply powers through.
Right Fit For
Renters and small-lot owners who need a nimble mower that disappears into a closet or a balcony storage bin.
A Better Fit Elsewhere
Anyone with uneven ground or thicker grass should step up to the Worx WG735, which adds IntelliCut torque control.
The Worx WG735 keeps the compact 14″ footprint of the WG733.1 above, but it doubles the voltage and adds IntelliCut, a system that automatically bumps torque when the blades meet thicker grass. For an overgrown patch after a vacation, that auto-adjustment matters more than raw deck size, and it is the headline feature that separates this pick from its smaller sibling.
The brushless motor again keeps noise down and should extend service life compared with brushed designs. A 20V 4.0Ah battery is included, and the deck accommodates up to an eighth of an acre per charge under normal conditions.
Where It Helps
- IntelliCut torque control spares the motor and the battery when the grass gets thick, which most owners eventually run into.
- The optimized deck airflow lifts clippings cleanly into the bag, reducing the clumping that often plagues small mowers.
- At a compact 14″ width, the WG735 tucks into narrow side-yard gates that block wider machines.
Trade Offs
- A 14″ deck is still slow going past an eighth of an acre, and wider-lot mowing will eat runtime fast.
- Single-battery runtime means a second pack is worth budgeting for owners with denser turf.
Key Specs
Made For
Owners of a small or irregularly shaped lawn with mixed grass thickness who want auto-torque on demand.
Consider Something Else When
Mowing a quarter acre or more, where the Worx WG745’s 17″ deck and dual batteries finish the job in fewer passes.
The Worx WG745 stretches the brand’s compact-mower DNA into proper suburban territory. Its 17″ deck and dual 20V 4.0Ah PowerShare batteries cover up to a quarter acre per charge, and a brushless motor keeps noise down on a Saturday morning. The dual-battery setup is the real trick: both packs feed the 40V platform together, and the same batteries slot into more than 140 other Worx tools, from string trimmers to pressure washers.
The dual charger included in the box refills both packs, so downtime between mows shrinks compared with single-battery models.
Useful Strengths
- Two 20V 4.0Ah packs deliver the runtime that single-battery 40V mowers like the WG735 often lack on bigger lots.
- Sharing batteries with the broader Worx PowerShare ecosystem reduces the chance of owning five different chargers.
- The 17″ deck strikes a balance between the maneuverability of a 14″ model and the speed of a 21″ deck.
Small Caveats
- It is still a push mower, so anyone on a slope may want to spend more for the EGO POWER+ self-propelled design.
- Bag capacity on a 17″ deck fills faster than on a wider deck, and stopping to empty cuts into runtime.

Not Your Match When
Anyone mowing a sloped or hilly property should consider the EGO POWER+ LM2135SP, since self-propulsion takes the strain off.
The EGO POWER+ LM2135SP is the most ambitious pick in this roundup, and the only one with self-propulsion. The 56V platform pushes up to 7.0 ft-lbs of torque, which puts it in gas-mower territory, and the Select Cut Multi-Blade System swaps between mulching, bagging, and extended-runtime blades. This bundle ships with both a 7.5Ah battery and a 5.0Ah pack, so larger yards get finished without waiting for a recharge mid-mow.
Owners with sloped or uneven lawns benefit most, because the rear-wheel drive does the pushing.
Everyday Advantages
- Self-propelled rear-wheel drive removes the physical effort that makes the Greenworks 80V and Worx models tiring on hills.
- The Select Cut blade system lets one mower handle mulching, bagging, and longer runtime without buying accessories.
- Two batteries in the box mean a mid-mow swap extends runtime for half-acre properties.
- The 56V 7.5Ah pack holds enough charge to handle a typical suburban lawn on a single battery.
Areas To Watch
- This is the priciest unit in the lineup, and shoppers with a flat small yard will not get full value from the self-propelled feature.
- Extra batteries and chargers can pile up in the garage if the household already runs on another brand’s platform.

Perfect Match For
Homeowners with sloped or half-acre lawns who want gas-like power without the maintenance routine.
Skip It When
Budget-focused shoppers with a flat small yard will do fine with the Worx WG733.1, which costs less and weighs far less.
The Litheli 40V closes the list with a thoughtful, mid-size design aimed at mixed-grass suburban yards. Its 16″ deck and 50L collection bag (about 13 gallons) keep stops to empty the bag to a minimum, and six adjustable cutting heights between 25 and 75 mm cover anything from a low-maintenance summer cut to a taller, drought-friendly setting. Both 5.0Ah batteries ship in the box, so there is no waiting on a separate charger purchase.
Both batteries must be inserted to power the mower, which keeps the output steady. A brushless motor rounds out the maintenance-free story.
Where It Delivers
- Six cutting heights between 25 and 75 mm give precise control over seasonal lawn care without swapping blades.
- The 50L bag holds more clippings than smaller mowers, cutting down on mid-mow emptying stops.
- Two 5.0Ah batteries in the box mean there is no waiting for an extra pack to arrive before the first mow.
Potential Drawbacks
- Litheli’s battery ecosystem is smaller than the Worx PowerShare lineup, so cross-tool flexibility is more limited.
- The 16″ deck sits between the agile 14″ picks and the faster 21″ options, without excelling at either extreme.

Who Should Grab It
Suburban homeowners with mid-size yards and a mix of grass types who value multiple cut-height options.
Reach For A Different Pick When
Owners committed to a broader battery platform should pick the Worx WG745, since its PowerShare batteries span far more tools.
What To Weigh Before Choosing A Cordless Mower
Battery voltage and deck width are the two numbers that drive most decisions, but the relationship between them is the part that catches first-time shoppers. A 40V platform with a 14″ deck behaves very differently from a 40V platform with a 17″ deck, because the wider blade demands more current. Pairs like the Worx WG735 and WG745 show how the same voltage can serve different yard sizes.
Runtime is the spec that varies most in the real world, since grass thickness, blade sharpness, and ambient temperature all swing the number. Any 40V or 56V platform will lose minutes in early spring or after a long vacation, so a second battery is often worth budgeting for even when the box says a single pack is enough.
Brushless motors, a design that uses electronic controllers instead of physical carbon brushes to spin the rotor, tend to last longer and run quieter than brushed motors, and every mower on this list uses one. The bigger differentiators are self-propulsion (only on the EGO POWER+ LM2135SP) and how widely the batteries cross over to other tools in the brand’s ecosystem, which matters once a trimmer or blower enters the picture.
For lots under 1,500 sq. ft., the Worx WG733.1 handles the job with minimal storage footprint. Quarter-acre lawns land squarely in Worx WG745 or Litheli territory. Anything approaching a half acre, or any property with a real slope, leans toward the EGO POWER+ LM2135SP.
Key Things To Keep In Mind
Pitfalls Shoppers Hit
The most common slip is matching voltage to lawn size and ignoring deck width. A high-voltage 14″ mower still makes a quarter-acre feel endless, while a wider deck on a low-voltage platform can stall in thick grass. Yard size and blade size need to grow together, not in isolation.
Another trap is assuming a single battery covers the listed runtime. Manufacturer estimates assume ideal grass length, dry conditions, and moderate pace. Real lawns are rarely that friendly, so planning for 60 to 70 percent of the claimed figure is closer to actual use.
When Paying More Pays Off
The jump from a compact 14″ model to the EGO POWER+ LM2135SP brings self-propulsion, a wider deck, and a multi-blade cutting system. That upgrade pays off most for anyone with slopes, half-acre lawns, or simply less desire to wrestle a mower on a hot afternoon. For flat small yards, the premium rarely earns its keep, and a smaller model leaves money in the budget for a string trimmer or leaf blower.
Frequently Asked Questions
How long do cordless mower batteries typically last?
Most modern 40V and 56V packs deliver around 500 to 1,000 full charge cycles before noticeable capacity loss, which usually means several years of weekly mowing. Storage in a cool, dry place and avoiding full discharges both help extend service life.
Are brushless motors actually worth the upgrade?
Brushless designs skip the carbon brushes that wear out in brushed motors, so they tend to run quieter, cooler, and last longer. For weekly mowing through a long season, the difference shows up most in motor longevity rather than cutting power.
Can one battery platform power the rest of my yard tools?
Some platforms, like Worx PowerShare, span well over a hundred tools, while others stay smaller. Matching your mower brand to a trimmer, blower, or chainsaw you already own can save the cost of duplicate batteries and chargers.
What deck size handles a quarter acre comfortably?
Most shoppers find a 17″ deck the sweet spot for a quarter acre, since it balances pass count against maneuverability. Smaller decks work but add passes, while wider 21″ decks feel faster but harder to steer around landscaping.
Do self-propelled mowers make sense on flat lawns?
On a flat lot, self-propulsion mainly saves effort on longer mow sessions. Owners with any slope will feel the difference every single mow, while flat-lot owners may decide the simpler push design of the Greenworks 80V is enough.
Closing Thoughts
The best cordless mower is the one that matches the lawn, not the one with the biggest spec sheet. Small urban lots do well with the Worx WG733.1, mid-size suburban yards fit the Worx WG745 or Litheli 40V, and any sloped or half-acre property is worth the premium for the EGO POWER+ LM2135SP. Pick the mower that fits the yard, and the rest of the season tends to take care of itself.
