Cordless walk-behind mowers have quietly outgrown their reputation as niche tools. Modern battery platforms deliver enough run time to handle a typical suburban lot on one charge, and the brushless motors keep things quiet enough for early Sunday mornings. Storage becomes a non-issue too, since most of these fold flat and roll into a garage corner.
I spend a lot of time thinking about which features actually matter for real lawns and which ones just inflate spec sheets. The seven cordless picks below cover a useful spread: compact options for tight urban plots, larger decks for quarter-acre yards, and modular battery systems for anyone already invested in a tool platform.
A Fast Comparison Of The Options
Greenworks 80V 21″ Push Lawn Mower 4.0Ah
Casince 17″ Walk Behind Cordless Lawn Mower
Worx 20V 14″ 2-in-1 Lawn Mower WG733.1
Worx 40V 14″ 2-in-1 Lawn Mower WG735
Worx 40V 17″ 2-in-1 Lawn Mower WG745
Makita DLM330Z 18V LXT Lawnmower
Litheli 40V 16″ Brushless Cordless Mower
The Details Behind The Selections
The Greenworks 80V sits in that sweet spot where the deck is wide enough to cut down passes on a half-acre lot, yet the body still folds flat for garage storage. A 21-inch cutting width covers ground quickly, and the steel deck adds the kind of weight that helps the mower track straighter through thicker grass without floating sideways.
The brushless motor is the headline feature here, essentially an electronically controlled motor that runs cooler and uses less battery than older brushed designs. A single-lever height adjustment keeps things simple when switching between regular cuts and tall spring growth. For homeowners who want one cordless mower that handles most situations, this is the most complete package in the lineup.
Where It Delivers
- 21-inch deck finishes a typical quarter-acre lot in noticeably fewer passes than 14- or 17-inch options
- Rapid charger reportedly refills the 4.0Ah pack in about an hour, useful for back-to-back weekend sessions
- Steel deck adds durability and helps the mower stay planted in uneven terrain
- Single-lever height adjustment means no fiddling with four separate wheels
Things To Consider
- At roughly 60 minutes of run time, larger properties over a half acre may need a second battery or a charge break
- The 21-inch footprint is heavier to push uphill than the smaller 14-inch alternatives below
Key Specs
Who It Suits Best
Homeowners with a medium-to-large suburban lot who want a single mower that handles most jobs without juggling extra batteries.
Look Elsewhere When
The Worx 40V 14″ 2-in-1 Lawn Mower WG735 is the better fit if your yard is small and you would rather have the lightest push on the market than a 21-inch deck.
The Casince 17-inch lands in the middle of the deck-size range, which makes it the most flexible option for irregular lot shapes. It comes with two 20V batteries rather than a single pack, and that dual-battery setup is what stretches the run time out to about 40 minutes under typical conditions.
Six height settings between 1 and 3 inches give meaningful range from a low clean-cut look to a tall spring growth trim. Compared with the Greenworks 80V above, this one is lighter and easier to push but trades away that extra deck width. For someone who values maneuverability over raw cutting speed, the trade makes sense.
Useful Touches
- 17-inch deck hits a balance between narrow-lot agility and faster passes than 14-inch models
- Six height settings from 1 to 3 inches accommodate seasonal growth swings
- Two included batteries let you finish a typical small yard without a mid-mow swap
- Lighter than the 21-inch Greenworks, so sloped lots are easier on the arms
Worth Noting
- Run time under heavy load drops faster than the 80V Greenworks, so thick spring grass may need a charge break
- Plastic deck components tend to show scuffs sooner than steel-deck rivals
Built With In Mind
Owners of small-to-medium lots up to about 5,000 square feet who want a flexible deck size and don’t need to mow an acre in one pass.
Consider Something Else When
The Greenworks 80V 21″ Push Lawn Mower 4.0Ah is a stronger pick for anyone whose priority is finishing a large yard in fewer passes.
The Worx WG733.1 is the easiest mower in this roundup to live with on a daily basis. It is the smallest and lightest model in the Worx lineup, which matters far more than people expect when navigating narrow side yards, gate openings, and the gap between a garden bed and a fence.
A 14-inch deck and a 20V 5.0Ah PowerShare battery cover yards up to roughly 3,200 square feet, plenty for most urban lots. The 2-in-1 deck switches between bagging and mulching without tools. Unlike the 40V models further down this list, this one trades cutting power for portability, so it shines on tidy plots rather than wild growth.
What Pays Off
- Lightest mower here, easy to lift over curbs and carry up basement steps
- 2-in-1 bagging and mulching switch is genuinely tool-free
- PowerShare battery works with other Worx 20V tools, useful if you already own their trimmers or blowers
- Brushless motor adds lifespan over older brushed designs at the same deck size
Honest Caveats
- 14-inch deck means more passes on any yard over about 2,500 square feet
- 20V platform has less torque than the 40V options, so wet or overgrown grass may stall the blade
The Right Fit
Urban gardeners with compact lots under 3,200 square feet who care more about maneuverability than finishing the lawn in record time.
Swap It Out When
The Litheli 40V 16″ Brushless Cordless Mower makes more sense for someone with mixed seasonal growth who wants more torque without jumping to a 21-inch deck.
The WG735 takes the compact Worx platform and adds two things that change the feel entirely: a 40V battery and Worx’s IntelliCut technology, which adjusts torque on the fly when the blade hits thicker grass. The result is a small mower that does not stall the moment conditions get uneven.
A single 20V 4.0Ah battery covers up to about an eighth of an acre on one charge. The optimized deck with Airflow design is a small but real upgrade over older Worx decks, lifting clippings so the bag fills more evenly. Compared with the WG733.1 above, the WG735 stays small but adds genuine muscle for thicker patches.
A Strong Showing
- IntelliCut automatically dials up torque in thicker grass, reducing stalls mid-mow
- Optimized deck with Airflow design helps the bag fill more evenly
- Same compact 14-inch footprint as the WG733.1, so storage stays easy
- Battery is swappable across the Worx 20V/40V PowerShare family
Points To Keep In Mind
- Run time shrinks noticeably in tall, wet grass, even with IntelliCut compensating
- The 14-inch deck still means extra passes on irregular lots that exceed an eighth of an acre

Where A Sibling Pick Shines
The Worx 40V 17″ 2-in-1 Lawn Mower WG745 covers more ground per pass and is the smarter buy for anyone regularly mowing a quarter-acre lot.
The WG745 is the Worx model built for larger suburban lots. A 17-inch deck and two 20V 4.0Ah batteries push the effective coverage up to about a quarter acre, which is the most demanding size that still makes sense for a walk-behind.
The dual-port charger is a small touch that pays off: both batteries refuel at once, so the next mow is ready when you are. The same PowerShare battery platform also powers more than 140 other Worx tools, which is a real advantage for anyone already building a yard-care setup around one ecosystem. Compared with the WG735 above, this is the bigger-deck sibling tuned for larger properties.
Useful Strengths
- Two included 20V batteries extend run time enough for a quarter-acre lot
- 17-inch deck handles wider passes than the 14-inch models without much extra weight
- Dual charger refuels both batteries at once
- PowerShare batteries swap into 140-plus other Worx tools and outdoor products
Trade Offs
- Heavier than the 14-inch Worx models, so small-framed users may feel the push on sloped sections
- 17-inch deck needs a slightly larger storage footprint than the compact 14-inch alternatives
Quick Facts
Best Suited To
Homeowners with quarter-acre lots who want a single mower that handles a full mow on one charge, especially those already invested in Worx’s PowerShare platform.
Another Choice May Suit
The Casince 17″ Walk Behind Cordless Lawn Mower is the better choice for shoppers who want similar deck width at a lower price point and don’t need the broader tool ecosystem.
The Makita DLM330Z is built for tradespeople, not first-time homeowners. It uses Makita’s 18V LXT slide-style battery platform, which is the same pack that runs hundreds of drills, impact drivers, and saws. If your garage already looks like a Makita catalog, this mower drops in without buying a new battery.
A 330mm cutting width is on the narrow side, but the mower pivots tightly enough for landscaping work around flower beds and corners. The soft-start feature ramps the motor up gently rather than jerking the blade. The honest read is that this is a specialty tool for existing Makita owners, not a starter mower for the casual shopper.
The Practical Payoff
- Uses the same 18V LXT batteries as the rest of Makita’s tool lineup
- 330mm deck pivots in tight radii, useful around flower beds and obstacles
- Soft-start feature is gentler on the motor and the user’s grip than hard-start designs
- 3-in-1 deck offers bagging, mulching, and side-discharge options
Where It May Fall Short
- Batteries and charger are not included, so first-time Makita buyers face a higher upfront cost
- Smaller 330mm deck means more passes than the 17- and 21-inch alternatives in this list
Perfect Match For
Makita platform users who want a cordless mower that slides into their existing battery system without buying a second charger setup.
Not Your Match When
The Worx 40V 17″ 2-in-1 Lawn Mower WG745 is the stronger choice for homeowners who don’t already own Makita batteries and want batteries included out of the box.
The Litheli 16-inch rounds out the list with a feature set that punches above its category. Both 5.0Ah batteries must be inserted to deliver the full 40V, and that dual-pack setup keeps the motor from sagging in the middle of a long mow.
Six adjustable cutting heights between 25 and 75mm give a generous range, more than most rivals at this deck size. A 50L collection bag plus mulching capability means clippings can either feed the lawn or go into the bin. Compared with the compact Worx models above, the Litheli adds a wider deck and a deeper bag without jumping into the 21-inch heavyweight class.
Points In Its Favor
- Six height settings from 25 to 75mm cover everything from ornamental grass to tall summer growth
- Brushless motor needs no oil changes or spark plugs, simplifying seasonal maintenance
- 50L collection bag holds more clippings than most 40L bags at this size
- Two 5.0Ah batteries share the load, which keeps voltage from dipping mid-mow
Practical Considerations
- Litheli’s battery ecosystem is smaller than Worx’s or Makita’s, so platform expansion is more limited
- 16-inch deck means more passes than the 21-inch Greenworks on larger lots
At A Glance
Who Should Grab It
Homeowners with mixed seasonal growth who want a wide range of cut heights and a larger collection bag without stepping up to a 21-inch deck.
Reach For A Different Pick When
The Greenworks 80V 21″ Push Lawn Mower 4.0Ah is the better match for anyone whose priority is finishing a half-acre yard as quickly as possible.
What Matters Most When Picking A Cordless Walk-Behind
A deck width under 16 inches makes sense for narrow side yards and gate access, but anything beyond a quarter acre starts to feel like extra work. Wider decks, in the 17- to 21-inch range, cut down passes and shorten mow time on larger lots. Run time is the second pillar: a 4.0Ah battery typically covers around 30 to 60 minutes under real conditions, while dual-battery setups stretch that further.
Brushless motors use electronic controllers instead of physical brushes to drive the rotor, which means less friction, more torque, and longer motor life. They are quieter too, which matters during early-morning mows in close-knit neighborhoods. Battery platform compatibility is the underrated factor. Worx’s PowerShare, Makita’s LXT, and Greenworks’ 80V systems let a single battery move between mowers, trimmers, blowers, and chainsaws, which saves real money over a few seasons.
Weight and storage matter more than spec sheets suggest. A lighter mower is easier on the back over a long session, and a folding handle saves significant garage space. For sloped lots, lighter models like the Worx WG733.1 make a noticeable difference in everyday comfort.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Buying on deck width alone often leads to oversize mowers that don’t fit through a side gate or garage door. Storage dimensions matter as much as cut quality, especially in tighter urban lots. Another common trap is overlooking whether batteries and chargers are included; bare-tool versions like the Makita DLM330Z only make financial sense if you already own the matching battery platform.
Where The Extra Money Goes
Higher-tier cordless mowers tend to invest in wider steel decks, brushless motors, and larger capacity batteries. Steel decks resist scuffs and UV damage longer than plastic. Brushless motors typically outlast brushed designs by years under regular use. Dual-battery systems are what allow 17- and 21-inch models to actually finish a full mow on one charge, and that extra capacity is where most of the added cost lives.
Frequently Asked Questions
How long does a cordless lawn mower battery actually last?
Most 40V 4.0Ah batteries deliver 30 to 60 minutes under typical mowing conditions, depending on grass thickness and deck size. Thicker grass and wider decks drain the pack faster.
Can a cordless mower handle a quarter-acre yard?
Yes, a 17-inch deck with two batteries, like the Worx WG745, is sized for that range. Smaller single-battery 14-inch mowers are best for lots up to about an eighth of an acre.
Are brushless motors worth the extra money?
Brushless motors typically run quieter, last longer, and use battery power more efficiently than brushed designs. For anyone mowing weekly, the upgrade pays off over the life of the mower.
Do these mowers mulch as well as they bag?
Most 2-in-1 and 3-in-1 cordless mowers mulch effectively at the middle height settings. Mulching works best on dry grass and may leave clumps if the lawn is overgrown.
How do I store a cordless mower over winter?
Most models fold flat for vertical storage in a garage or shed. Batteries should be stored indoors at moderate temperatures and kept at about half charge during long storage periods.
The Takeaway
The right cordless mower depends on lot size, grass type, and how much storage space you have to spare. Smaller urban lots lean toward compact 14-inch picks like the Worx WG733.1, while quarter-acre properties benefit from the wider 17-inch decks and dual-battery setups. Whichever model fits, going cordless turns a Saturday chore into a quieter, cleaner routine.
