Battery technology has quietly rewritten what a walk-behind mower can do. The cordless machines below cover everything from postage-stamp backyards to half-acre lawns, and they swap petrol exhaust for the hum of a brushless motor. If you’ve been holding onto a temperamental gas engine because you assumed battery meant underpowered, this roundup is worth a look.
The Lineup, Simplified
Greenworks 80V 21in Push Lawn Mower 4.0 Ah
Casince 17 in Walk Behind Lawn Mower
Honda HRX217YXBEXA6 21-Inch Battery Mower
Makita DLM330Z 18V LXT Lawnmower
Litheli 40V 16 Inch Cordless Push Mower
Litheli 14 Inch Cordless Brushless Mower
Taking A Closer Look At The Options
The Greenworks 80V brings a steel deck to a category that’s mostly plastic, and that single detail sets the tone for everything else. It’s a 21-inch walk-behind, which is wide enough to trim a quarter-acre yard without eating your entire Saturday. You get a brushless motor (a design that skips the carbon brushes that wear out on cheaper brushed motors), so the unit runs quieter and typically outlasts its brushed cousins.
For anyone replacing a tired petrol mower and dreading the maintenance, the included 4.0Ah battery and 60-minute rapid charger change the math. There’s no oil, no spark plug, no fuel stabilizer to drain before winter. Single-lever height adjustment means you tweak all four wheels in one motion, useful when you shift from a spring trim to a summer cut.
Everyday Wins
- Steel deck resists cracking and UV warping better than plastic
- Brushless motor runs quieter, so early-morning mowing won’t wake the neighbors
- Single-lever height adjustment is faster than per-wheel tweaking on cheaper mowers
- Up to 60 minutes of runtime covers most suburban lots in one pass
- Rapid charger tops off a depleted pack in roughly an hour
Things To Consider
- At roughly 60+ pounds with the battery, it’s heavier than the Litheli 14 Inch model below
- Runtime drops noticeably in tall, wet grass
Key Specs
Who It Suits Best
Owners of medium suburban lawns who want a steel-deck workhorse without the petrol maintenance schedule.
Where Another Pick Suits Better
If you already own Makita LXT batteries, the Makita DLM330Z slots into your existing tool family without buying a new platform.
The Casince sits in the comfortable middle ground: smaller than the Greenworks and Honda, larger than the Litheli 14. Its 17-inch deck handles a tidy suburban lot without the bulk, and the dual 20V battery system runs the two packs in series to deliver 40V of cutting power. That’s a clever way to stretch runtime without forcing you to swap packs mid-lawn.
Six height settings from 1 to 3 inches give you fine control over seasonal cuts, which matters when the lawn goes from springy short to summer-thick in a few weeks. Compared to the Greenworks above, you trade steel-deck durability for a lighter footprint and easier storage.
Strengths Worth Knowing
- Two 4.0Ah batteries run in series, extending runtime to roughly 40 minutes
- Six height positions let you dial in anything from a manicured 1-inch trim to a 3-inch cut
- 17-inch deck balances maneuverability with reasonable coverage
- Cover area of up to roughly 5,380 square feet per charge under ideal conditions
Worth Noting
- Two batteries mean two separate charging cycles when they eventually drain
- Build is more plastic than the Greenworks steel deck
Made For
Homeowners with small to medium lawns who want flexibility on cut height without stepping up to a 21-inch deck.
Consider Something Else When
If your lawn tops a quarter acre and you cut less often, the Honda HRX217YXBEXA6 offers the runtime and 4-in-1 versatility to handle taller growth.
Honda’s HRX-BE is the battery translation of their flagship HRX platform, and it doesn’t apologize for its ambitions. The 21-inch deck pairs with Honda’s Versamow system, which is a 4-in-1 design that lets you switch between mulching, bagging, discharge, and leaf-shredding without swapping parts. The Clip Director knob lets you toggle between modes on the fly.
The motor is engineered to mirror the torque curve (a graph showing how twisting force changes with RPM) of Honda’s gas GCV engines, so RPMs hold steady when the grass gets thick. That’s a meaningful upgrade over cheaper brushless motors that bog down in heavy conditions.
Notable Upsides
- 4-in-1 Versamow with Clip Director handles bagging, mulching, discharging, and leaf shredding
- Honda-grade motor tuning maintains cutting speed in thick or damp grass
- Twin blade MicroCut system produces finer clippings for cleaner mulching
- Self-propelled drive reduces fatigue on larger or sloped lawns
Trade Offs
- Premium pricing reflects the Honda engineering and 4-in-1 versatility
- Battery and charger availability can vary by region
Feature Card
Right Fit For
Lawn-care enthusiasts who switch between bagging and mulching across the season and want Honda’s build quality without petrol.
Skip It When
Casual users with small lawns may not tap into the Versamow system, and the Litheli 40V 16 Inch model covers that ground more affordably.
The Makita DLM330Z is the bare-tool version, meaning batteries and charger ship separately. That phrasing matters: if you already own Makita LXT gear, this mower slides into your existing charger and battery fleet. If you don’t, factor in the cost of an 18V pack before the math makes sense.
The deck is compact at around 13 inches, which is the narrowest in this roundup. That’s a deliberate trade. You give up swath width for the ability to thread through narrow side-yard gates and pivot in tight beds. Soft start ramps up the motor gradually, which is easier on the gears and quieter at ignition.
A Favorable Mix
- LXT battery compatibility means no new charger or batteries for existing Makita owners
- Compact deck pivots easily around garden beds and narrow gates
- Soft start protects the motor and gears on startup
- Up to 4,300 RPM delivers clean cuts through typical lawn grass
Honest Caveats
- Batteries and charger are not included, which inflates the real cost for new Makita households
- Smaller deck means more passes on larger lawns
Best Suited To
Tradespeople and DIYers already invested in Makita’s 18V LXT platform who want a tidy secondary mower for smaller spaces.
Look Elsewhere When
If you don’t already run LXT tools, the Greenworks 80V gives you a complete battery-and-charger kit out of the box.
The Litheli 40V leans into the dual-battery approach with both packs inserted at once, so the mower delivers full 40V performance throughout the cut. That’s different from systems that run a single battery and swap, which can lose power as the pack drains. The included 50L collection bag is generous for a 16-inch deck.
Six height positions spanning 25 to 75mm (about 1 to 3 inches) let you match the cut to seasonal growth, and the mulching capability means you can skip bagging entirely when clippings are short. Compared to the Casince above, you get a slightly narrower deck but a noticeably bigger bag.
A Few Highlights
- Both 5.0Ah batteries must be installed, ensuring consistent 40V power without drop-off
- 50L collection bag holds more clippings than most 16-inch mowers
- Six height adjustments from 25 to 75mm cover everything from short trim to tall summer cut
- Brushless motor removes the carbon brushes that wear out on cheaper brushed designs
Points To Keep In Mind
- You need to charge two batteries to keep the mower running, doubling the dock space
- Smaller deck means more passes on quarter-acre lawns
Quick Facts
Who Should Grab It
Suburban homeowners who want mulching flexibility and a sizeable bag without stepping up to a 21-inch workhorse.
Reach For A Different Pick When
If storage space is tight, the Litheli 14 Inch folds flatter and weighs noticeably less.
The Litheli 14 Inch is the smallest mower in this roundup, and it knows it. The deck is narrow enough to slip through standard garden gates, and the quick-fold handle shrinks the whole package to something that fits in a closet. For townhouse dwellers or anyone with a postage-stamp yard, that’s the entire pitch.
The 5.0Ah battery covers up to roughly 3,000 square feet per charge, which handles most small urban lawns on a single pass. Five height positions from 1 to 2.5 inches give you enough range for the seasons without overcomplicating the controls. Versus the Litheli 40V model above, you give up the second battery and the wider deck in exchange for a much lighter footprint.
What Helps Most
- Foldable handle reduces the mower to a closet-friendly footprint
- Lightweight design is manageable for users who find larger mowers tiring
- Brushless motor needs no oil, spark plug, or carburetor service
- Up to roughly 3,000 square feet of coverage per charge for typical small lawns
A Few Limitations
- 14-inch deck requires more passes on anything beyond a small yard
- Height range tops out at 2.5 inches, limiting taller summer cuts
Perfect Match For
Apartment and townhouse owners with small lawns or tight storage who want a mower they can fold and tuck away.
A Better Fit Elsewhere
For larger or more demanding lawns, the Greenworks 80V 21in Push Lawn Mower gives you a wider deck and longer runtime in one package.
What Matters Most Before Choosing Petrol Lawn Mowers
Deck Size And Lawn Footprint
A 21-inch deck shaves time off a quarter-acre yard but feels bulky on a tight lot. Match the deck to the lawn: small urban yards do fine on 14 to 17 inches, mid-size suburban lots want 18 to 21 inches, and anything beyond a half acre usually demands self-propelled drive.
Battery Platform And Runtime
Cordless mowers live or die on battery strategy. Single-battery systems are simpler but offer shorter runtime; dual-battery designs extend runtime but require charging both packs. Brushless motors (which ditch the carbon brushes that wear out on cheaper brushed designs) tend to last longer and run quieter, though they typically cost more upfront.
Cutting Modes And Versatility
If you switch between bagging, mulching, and side discharge across the season, look for a 4-in-1 deck. Single-mode mowers cost less but force you into one approach all year. Honda’s Versamow system with Clip Director is the most flexible example in this roundup.
Storage And Maneuverability
Quick-fold handles and lighter decks matter more than spec sheets suggest. A mower that hangs in a garage or stands in a closet actually gets used; a heavy unit that lives in the driveway tends to collect excuses.
Common Shopping Slip Ups And Why Top Tier Costs More
Pitfalls Shoppers Hit
Underestimating runtime is the classic mistake. Manufacturers quote runtime under ideal conditions, but thick or wet grass drains packs faster. Buy for roughly 80% of the stated runtime and you’ll never run out mid-lawn.
Ignoring storage dimensions bites apartment dwellers. A 21-inch mower that doesn’t fold takes up real estate you may not have. Measure the closet or garage spot before you fall for a wider deck.
Where The Extra Money Goes
Premium tiers tend to buy better motors, steel decks, and 4-in-1 versatility. The Honda HRX-BE earns its position with Versamow and torque-holding motor tuning. For small lawns, that premium is overkill. For demanding turf, it’s the difference between a clean cut and ragged tips.
