Going cordless used to feel like a compromise. Not anymore. I put together this shortlist for anyone tired of gas-engine upkeep, tangled cords, or weekend trips to the repair shop. These six walk-behind options cover everything from a tidy city lawn to a third-of-an-acre suburban lot, so you can match the mower to your yard instead of the other way around.
Your Options, Compared
Greenworks 80V 21in Push Lawn Mower (4.0 Ah)
Casince 17in Cordless Walk-Behind Lawn Mower
EGO POWER+ LM2135SP 21in Self-Propelled Mower
Honda HRX-BE 21in Battery Mower (HRX217YXBEXA6)
Honda HRX-BV 21in Battery Mower (HRX217YXBVKA4)
Litheli 40V 16in Brushless Cordless Mower
Taking A Closer Look At The Options
The Greenworks 80V lands at the top of this list because it hits a comfortable middle ground. A brushless motor (the kind that uses electronic control instead of carbon brushes, which generally means longer life and quieter operation) drives a 21-inch steel deck, which is wide enough to chew through a typical quarter-acre yard without endless passes. The included 4.0Ah battery fully recharges in roughly an hour, so weekend mowing rarely turns into a multi-hour charging ritual.
Compared to the smaller Casince that follows it, the Greenworks has noticeably more cutting width and a tougher deck material. For homeowners managing a mid-size lawn with mixed grass types, that extra width and torque matters more than the smaller footprint.
Positive Takeaways
- Up to about 60 minutes of runtime per full charge, which usually covers a small-to-mid suburban lot in one go.
- Single-lever height adjustment lets you step through deck heights quickly, useful when switching between sidewalks and taller back lawn.
- Brushless motor tends to run quieter and last longer than brushed alternatives in this category.
- Steel deck handles bumps and rough ground better than plastic alternatives.
- Rapid charger brings the 4.0Ah pack back from empty in roughly 60 minutes.
Things To Consider
- It’s a push mower, so on a sloped or large lawn you may find the self-propelled EGO option easier on your legs.
- Run-time drops in tall, wet grass; mowing conditions change the math considerably.
- Steel adds weight, and storing it in a tight shed may take more effort than the Litheli below.
Key Specs
Who It Suits Best
Homeowners with a quarter- to third-of-an-acre lawn who want a steel-deck workhorse without stepping into self-propelled pricing.
Look Elsewhere When
Anyone dealing with hills or a large lot should consider the EGO POWER+ LM2135SP, which does the pushing for you.
The Casince 17-inch is the option I’d point a first-time cordless owner toward. Its 17-inch deck sits between compact and full size, and six height settings from about 1 to 3 inches give enough range to handle most lawn species. Two 20V 4.0Ah batteries run in tandem (called a dual-battery setup, meaning both packs must be inserted for the mower to operate), which the brand rates for around 40 minutes of mowing or roughly 5,380 square feet per charge under ideal conditions.
Side by side with the Litheli at the bottom of this list, the Casince offers a wider cut and a more traditional walk-behind shape. Side by side with the Greenworks above, it’s lighter and easier to store, but it gives up cutting width and deck material.
The Case For It
- Six cutting heights (roughly 25 to 75 mm) cover most grass types without swapping parts.
- Dual-battery setup extends runtime beyond what a single-pack mower in this size class typically offers.
- Smaller deck and lighter build make storage in a closet or small shed realistic.
- Lower entry price than 21-inch self-propelled options.
Worth Noting
- Runtime figures assume light cutting conditions; thick or wet grass drains the packs faster.
- 17-inch deck means more passes than a 21-inch mower on the same yard.
- Lightweight construction can feel less planted on uneven ground compared to steel-deck models.
Made For
Small-yard homeowners and renters who need a manageable, storable mower without overspending.
Consider Something Else When
Anyone mowing more than roughly 5,000 square feet regularly should step up to the Greenworks 80V, which finishes the job in fewer passes.
The EGO POWER+ LM2135SP is the one I’d grab for a larger lawn or any yard with a slope. It pairs a 21-inch deck with a self-propelled drive, so the rear wheels do the pushing when you squeeze the bail bar. A 56V 7.5Ah battery ships with the mower and a second 5.0Ah pack is included in the bundle, which gives you genuine flexibility to swap mid-mow without sitting around for a recharge.
Versus the Greenworks above, the EGO trades push effort for added cost and weight. Versus either Honda in this list, it leans more on raw torque and battery flexibility than on traditional 4-in-1 cutting modes.
Strengths Worth Knowing
- Self-propelled drive noticeably reduces fatigue on slopes or long mowing sessions.
- Two batteries in the bundle mean you can keep one charging while the other works.
- 56V platform generally handles thick, damp grass without bogging down.
- Brushless motor construction lines up well with long-term ownership.
Trade Offs
- Higher sticker price than the Greenworks or Casince options.
- Heavier than a plain push mower, which can complicate lifting into a truck bed.
- Extra battery ships separately, so the full bundle takes a little patience to assemble.

Homeowners with larger or sloped lawns who want self-propelled help and the option to swap batteries mid-mow.
Reach For A Different Pick When
Anyone on a tighter budget or with a small, flat yard will get everything they need from the Casince.
The Honda HRX-BE is built around Honda’s battery platform but borrows heavily from the brand’s gas-engine DNA. The standout feature is the 4-in-1 Versamow system with Clip Director, which lets you switch between mulching, bagging, side discharge, and leaf-shredding without swapping attachments. The twin-blade MicroCut setup is designed to clip grass into finer pieces than a single-blade deck, which can leave a cleaner look and reduce thatch buildup over time.
Compared with the EGO above, the HRX-BE focuses less on raw speed and more on cut quality and versatility. It sits closer in spirit to the HRX-BV below, but the BE version emphasizes a different configuration of the same Honda engineering.
A Few Strong Suits
- Versamow system with Clip Director handles four cutting modes without tools or add-ons.
- Twin-blade MicroCut design tends to produce a finer, more even cut than single-blade decks.
- 21-inch deck covers full-size lawns efficiently.
- Honda engineering generally points to long mechanical life.
Honest Caveats
- Premium pricing puts it above most cordless competitors.
- Owners commonly note Honda battery mowers have a learning curve around battery care compared to plug-and-play designs.
Quick Facts
Who Will Love This
Detail-oriented homeowners who mulch, bag, and shred leaves through the season and value cut quality above raw speed.
A Better Fit Elsewhere
Anyone focused on self-propelled convenience over cutting versatility will appreciate the EGO POWER+ LM2135SP more.
The Honda HRX-BV shares most of its core DNA with the HRX-BE above. Both use Honda’s battery platform, a 21-inch deck, and the 4-in-1 Versamow system with Clip Director for switching between mulching, bagging, side discharge, and leaf shredding. The differences show up in configuration, color, and bundle details rather than in the bones of the machine.
For shoppers choosing between this and the BE version, the decision usually comes down to availability and the specific bundle or finish you prefer. Versus the EGO above, this Honda trades battery flexibility for cut versatility and traditional Honda build philosophy.
Why It Works Well
- Versamow Clip Director lets you handle four mowing modes without changing attachments.
- 21-inch steel-style deck covers a full-size lawn in fewer passes.
- Honda-grade components tend to hold up across many mowing seasons.
- Compatible with Honda’s broader battery ecosystem for existing Honda tool owners.
Points To Keep In Mind
- Premium price tier puts it well above basic cordless options.
- Battery and charger specifics vary by bundle, so it’s worth confirming what ships in the box.
- Like other Honda battery mowers, it weighs more than the Casince or Litheli options.
The Right Fit
Long-term owners who already trust Honda’s durability and want a battery mower with the brand’s traditional engineering feel.
Swap It Out When
Anyone chasing self-propelled drive or a wider battery bundle will find the EGO POWER+ LM2135SP a stronger match.
The Litheli 40V is the smallest mower in this roundup, and that’s the point. A 16-inch deck, a brushless motor, and a 50-liter collection bag make it a tidy package for tight spaces. Two 5.0Ah batteries ship in the box, and the mower needs both packs inserted to run, which keeps voltage stable through longer sessions. Six height settings from 25 to 75 mm match the adjustment range of the larger Casince.
Set next to the Casince above, the Litheli trades a slightly smaller deck for a brushless motor (the Casince’s motor type isn’t specified in its source data). Set next to the Greenworks at the top, it’s clearly the storage-friendly option for anyone short on shed space.
Useful Touches
- Compact 16-inch deck fits through narrow gates and stores in tight closets or sheds.
- Brushless motor design supports quieter operation and longer mechanical life.
- Two 5.0Ah batteries in the box extend runtime for a small yard.
- Six cutting heights (25 to 75 mm) match typical homeowner grass preferences.
Some Limits To Know
- 16-inch deck means noticeably more passes than 21-inch mowers on any sizable lawn.
- Both batteries must be inserted to operate, which is a small step some shoppers may overlook.
- Smaller collection bag fills up faster than the larger units on bigger properties.

Perfect Match For
Apartment or townhome owners with a small patch of lawn and limited storage who still want brushless-motor quality.
Where A Sibling Pick Shines
Homeowners with a slightly larger lawn will find the Casince’s 17-inch deck finishes the job in fewer passes.
What To Weigh Before Picking A Cordless Mower
Deck Size Versus Yard Size
A 21-inch deck cuts more grass per pass, which matters once your lawn grows past roughly 5,000 square feet. Below that, a 16- or 17-inch mower handles the job without fatigue and stores more easily. Match the deck to the lawn rather than chasing the widest option available.
Battery Voltage And Runtime
Higher voltage systems (56V or 80V, like the EGO and Greenworks here) generally deliver more torque in thick grass than 20V or 40V setups. Runtime claims assume light mowing conditions, so plan for less when cutting tall or damp grass. Dual-battery mowers like the Casince and Litheli extend usable runtime without forcing you to swap mid-mow.
Push Versus Self-Propelled
A self-propelled mower, such as the EGO POWER+ LM2135SP, pulls itself forward when you engage the bail bar, which makes a real difference on slopes or larger properties. For flat, smaller yards, a push mower keeps things lighter and often less expensive.
Cut Modes And Versatility
If you mulch some weeks and bag others, a 4-in-1 system like Honda’s Versamow (HRX-BE and HRX-BV) avoids tool changes. Basic 2-in-1 setups handle most homeowners fine, but a wider mode selection becomes valuable once leaves start dropping.
Key Considerations Across These Picks
Common Shopping Slip Ups
Buying purely on deck size can backfire, since a 21-inch mower in a tight side yard is awkward to maneuver. Conversely, picking a compact 16-inch model for a half-acre lawn turns mowing into a longer chore than it needs to be. Map your yard size and storage space before settling on a deck width.
Where The Extra Money Goes
Higher-tier cordless mowers invest in brushless motors, larger batteries, and self-propelled drive systems that reduce fatigue and extend mechanical life. The premium Hondas add cut-mode versatility with the Versamow system, which can justify the step up for anyone who mulches and bags seasonally. For flat, smaller yards, the value end of this list covers the basics without leaving performance on the table.
Frequently Asked Questions
How long does a cordless lawnmower battery typically last?
Most modern lithium-ion packs hold useful capacity for around three to five mowing seasons before you notice runtime dropping noticeably. Storing batteries at room temperature and avoiding full discharge in storage extends their working life.
Are brushless motors worth the upgrade?
For most homeowners, yes. Brushless motors produce less heat, run quieter, and tend to outlast brushed equivalents, which matters across years of weekend mowing.
Can a cordless mower handle thick or wet grass?
Higher-voltage models like the 80V Greenworks or 56V EGO manage thick growth better than lower-voltage options. Wet grass still strains any mower, so waiting for drier conditions preserves cut quality and runtime.
How much yard can a cordless mower cover per charge?
Run-time ratings assume ideal conditions, so plan for somewhat less in real lawns. A 4.0Ah battery on the Greenworks is rated for up to about 60 minutes, while dual-battery models like the Casince and Litheli stretch that further by drawing from two packs.
Is self-propelled worth it for a small yard?
For flat lawns under a quarter acre, push mowers are usually fine. Once you add slopes or longer mowing distances, self-propelled drive noticeably reduces effort, which is why the EGO POWER+ LM2135SP stands out for larger properties.
Closing Remarks
The right cordless mower lines up with your yard’s size, terrain, and storage realities. For most homeowners, the Greenworks 80V covers the middle ground well, while the EGO POWER+ LM2135SP earns its place on larger or sloped lots. Smaller yards and tighter storage spaces point toward the Casince or Litheli, and the two Hondas round out the list for anyone who treats cut quality and versatility as the top priority.
