Pulling the starter cord on a Saturday morning used to feel like a small workout. These days, electric start lawn mowers skip the rope entirely, and the lineup below covers everything from compact push models to self-propelled heavy hitters. I wrote this roundup for homeowners ready to leave gas behind, whether the lawn is a tidy city patch or a sprawling suburban yard.
A Side-By-Side Look
Greenworks 80V 21in Push Lawn Mower
Casince 13-Inch Cordless Walk-Behind Mower
EGO POWER+ 21in Self-Propelled LM2135SP
Honda HRX-BE 21in Walk-Behind Mower
Litheli 40V 16in Cordless Brushless Mower
Litheli 14in Brushless Push Mower
A Breakdown Of The Leading Choices
The Greenworks 80V 21in Push Lawn Mower is the kind of workhorse that makes sense for a typical backyard without forcing you to wrestle a gas engine. Its 21-inch steel deck covers ground quickly, and the brushless motor (a motor with no carbon brushes, which means less friction, quieter runs, and longer life) holds torque well through thicker grass. The included 4.0 Ah battery recharges in around an hour on the rapid charger, so most folks can mow top-to-bottom and still have time for a second pass later.
Single-lever height adjustment keeps things simple when switching between weekly trims and longer summer cuts. For a homeowner who wants a clean switch from gas to battery, this is the friendliest first step on the list.
Useful Touches
- Rapid charger refills the 4.0 Ah battery in roughly an hour, handy for back-to-back mow sessions.
- Brushless motor runs quieter and tends to outlast brushed designs, which matters for anyone mowing weekly.
- 21-inch deck covers a standard suburban yard in fewer passes than smaller 13 or 14-inch models.
- Single-lever height adjustment means one motion handles all four wheels, no fiddling per corner.
Things To Consider
- Push-only design, so sloped lawns take more leg work than the EGO self-propelled model below.
- Heavier than the 13 and 14-inch options, which may be a factor for anyone carrying it up basement stairs.
Key Specs
Who It Suits Best
Homeowners with a flat, medium-sized yard who want dependable battery power without paying premium-tier prices.
Where Another Pick Suits Better
Anyone mowing a steep or uneven lawn should consider the EGO POWER+ 21in Self-Propelled LM2135SP for its drive-assist wheels.
Small urban lawns don’t need a 21-inch beast, and the Casince 13-Inch Cordless Walk-Behind Mower leans into that reality. The 13-inch cutting deck slips between raised beds, narrow side yards, and tight corners without scraping fences. Five height settings between roughly 1 and 2.6 inches give enough range for weekly trims or a slightly longer summer cut.
Underneath, a brushless motor spinning at 3000 RPM delivers up to 1200W at peak, which is more than enough to keep the blade moving through typical city-lawn grass. For a first-time mower shopper in an apartment or townhouse, the small footprint here is a genuine advantage over the Greenworks above.
What Helps Most
- Compact 13-inch deck navigates tight gates and narrow pathways where larger mowers get stuck.
- Five height settings span 1 to 2.6 inches, covering most small-lawn preferences.
- Brushless motor at 3000 RPM delivers consistent cut quality without bogging down.
Worth Noting
- Narrow deck means more passes for any lawn over a few hundred square feet.
- Small-frame build may feel less sturdy on uneven ground than the Honda or Litheli 16-inch option.
Right Fit For
City dwellers and townhouse owners with a postage-stamp yard who value storage size over cutting width.
Skip It When
Anyone with a medium or large yard should step up to the Litheli 40V 16in Cordless Brushless Mower for better runtime.
The EGO POWER+ 21in Self-Propelled LM2135SP is the pick that earns its keep on bigger, tougher lawns. Where the Greenworks and Casince rely on your legs, this one drives itself, so slopes and half-acre yards stop feeling like a chore. The 56V platform delivers up to 7.0 ft-lbs of torque, which EGO equates to gas-engine power for typical mowing, and the Select Cut multi-blade system swaps between mulching, bagging, and extended-run blades depending on the day.
This bundle ships with a 7.5 Ah battery plus an extra 5.0 Ah battery, effectively doubling your working time before a recharge. For anyone tired of finishing a lawn in stages, that reserve pack changes the routine.
Well-Handled Touches
- Self-propelled drive saves effort on hills and long straight runs, a real upgrade over push-only designs.
- Select Cut multi-blade system lets you swap between mulching, bagging, and runtime-optimized blades.
- Dual battery bundle (7.5 Ah plus 5.0 Ah) covers most large yards without a mid-mow recharge.
- 56V battery platform produces gas-comparable torque for thick or damp grass.
Trade Offs
- Premium pricing sits well above the Greenworks and Litheli options in this roundup.
- Self-propelled drive adds weight, which may matter when carrying the mower up steps.

Made For
Homeowners managing half-acre or larger lawns with slopes who want gas-like cutting without the maintenance.
A Better Fit Elsewhere
Anyone working with a flat small yard can save money and weight by choosing the Casince 13-Inch Cordless Walk-Behind Mower.
The Honda HRX-BE 21in Walk-Behind Mower (model HRX217YXBEXA6) brings Honda’s reputation for durable outdoor power into the battery era. Its 4-in-1 Versamow system with Clip Director lets you mulch, bag, discharge, or shred leaves without swapping attachments, which is a practical edge over single-mode electric mowers. The battery-powered Honda motor is engineered to match the torque profile of the brand’s well-known GCV gas engines.
For homeowners who already trust Honda mowers and just want a cordless version, this is the obvious jump. The build quality is noticeably heavier-duty than the Litheli and Casince models above.
The Helpful Details
- 4-in-1 Versamow with Clip Director handles mulching, bagging, discharge, and leaf shredding in one unit.
- Honda battery motor tuned to match GCV gas-engine torque for thick grass.
- Twin-blade deck design improves cut quality and reduces clumps.
Honest Caveats
- Premium pricing, on par with the EGO POWER+ bundle but without the self-propelled drive.
- Heavier steel construction may be overkill for a small city lawn.

Reach For A Different Pick When
Anyone prioritizing self-propelled drive should look at the EGO POWER+ 21in Self-Propelled LM2135SP instead.
The Litheli 40V 16in Cordless Brushless Mower sits in a useful middle ground between the compact Casince and the 21-inch Greenworks. Its dual 5.0 Ah battery system must run both packs together to deliver full 40V output, which keeps voltage steady across the cut and helps prevent the power sag you sometimes see in smaller single-battery mowers. Six height settings between 25 and 75 mm offer finer tuning than most rivals, and a 50-liter collection bag means fewer stops to empty clippings.
For mulching fans, the deck switches modes without tools. This is a flexible pick for someone whose yard is too big for a 13-inch mower but not quite big enough to justify the EGO or Honda price.
A Strong Showing
- Dual 5.0 Ah batteries deliver consistent 40V output without mid-cut voltage drop.
- Six height settings from 25 to 75 mm allow more precise cut height than most rivals.
- 50-liter collection bag reduces trips to the compost pile on larger yards.
- Switchable mulching and bagging modes without extra tools.
Points To Keep In Mind
- Both batteries must be installed to operate, so losing one pack means no mowing until a replacement.
- Push-only, so steep lawns take more effort than the EGO self-propelled model.
Whose Shelf It Belongs On
Mid-yard homeowners who want mulching flexibility and longer runtime without stepping into premium-tier pricing.
Where A Sibling Pick Shines
Anyone needing true hands-off mowing on a slope will find the EGO POWER+ 21in Self-Propelled LM2135SP more comfortable.
The Litheli 14in Brushless Push Mower is the lightest, most compact option in this roundup, and that shows up the moment it leaves the box. Its quick-fold handle collapses the deck into a flat shape that slides into a closet or tight garden shed with no hassle. The included 5.0 Ah battery covers up to 3000 square feet on a charge, enough for most small suburban lots.
Compared to the Casince, this Litheli adds an extra inch of cutting width and a slightly more refined height-adjustment lever, but it stays in the same easy-storage category. It’s a comfortable pick for seniors or anyone who doesn’t want to wrestle a heavy frame out of storage.
The Value In It
- Quick-fold handle design fits inside small closets and tight sheds.
- Covers up to 3000 square feet per charge, enough for most small suburban lawns.
- Lightweight build is easy to carry and maneuver for seniors or smaller-framed users.
- Zero-maintenance brushless motor means no oil, no spark plugs, no carburetor cleaning.
Minor Gripes
- Smaller 14-inch deck means more passes than the 16-inch Litheli or 21-inch Greenworks.
- Push-only design, so very large lawns may feel like a workout.
Feature Card
Who Will Love This
Small-lawn homeowners and seniors who want a mower that stores easily and starts with the push of a button.
Not Your Match When
Anyone mowing more than a third of an acre regularly should look at the Greenworks 80V 21in Push Lawn Mower for fewer passes.
What To Weigh Before Choosing A Battery Mower
A bigger deck means fewer passes, but it also adds weight and storage headaches. For lawns under a quarter acre, a 13 to 16-inch deck handles the job without dominating the garage. Once the yard crosses half an acre, a 21-inch deck like the Greenworks or Honda saves real time per cut.
Battery voltage matters more than the marketing claims suggest. A 40V platform like the Litheli 40V 16in Cordless Brushless Mower delivers steady torque through thicker grass, while 56V and 80V systems (EGO, Greenworks, Honda) push harder in damp or overgrown conditions. Higher voltage also tends to mean longer runtime per amp-hour.
Brushless motors are now standard across most picks here. They skip the carbon brushes that wear out in older brushed designs, which means quieter operation and longer motor life. For anyone mowing weekly across multiple seasons, that detail matters more than peak power numbers.
Matching The Mower To The Yard
Flat, open lawns welcome any push mower on this list, and a single 4.0 to 5.0 Ah battery covers the cut comfortably. Sloped or uneven terrain is where self-propelled drive earns its keep, which is why the EGO POWER+ 21in Self-Propelled LM2135SP stands out for hilly properties. Tight urban lots with narrow gates call for compact 13 or 14-inch decks from Casince or Litheli.
Storage is the silent dealbreaker for many shoppers. Quick-fold handles, like the one on the Litheli 14in Brushless Push Mower, make apartment living realistic. Anyone with a garage and a standard workbench can usually handle the bigger 21-inch frames without trouble.
Key Considerations Across These Picks
Mistakes Worth Dodging
The most common slip is buying a deck size that doesn’t match the lawn. An overpowered 21-inch mower in a tiny yard just adds storage weight, while an undersized 13-inch deck on a half-acre lawn burns through battery life twice over. Also worth watching: assuming a single battery is always enough. Dual-battery setups like the Litheli 40V 16in Cordless Brushless Mower exist precisely because mid-yard mow sessions can stretch past a single pack’s runtime.
Where The Extra Money Goes
Premium-tier picks like the Honda HRX-BE 21in Walk-Behind Mower and the EGO self-propelled bundle charge more for heavier steel decks, self-propelled drive, and brand-name motor engineering. For flat, small lawns, the upgrade rarely earns its keep. On larger or sloped properties with thick grass, the extra torque and drive assistance pay back every Saturday.
Frequently Asked Questions
How long does a battery lawn mower actually run on one charge?
Most residential battery mowers on this list deliver between 30 and 60 minutes per charge, depending on grass thickness, deck size, and battery capacity. The 4.0 Ah pack on the Greenworks covers a typical medium yard, while dual-battery picks like the Litheli 40V 16in extend that window further.
Are electric start mowers harder to maintain than gas models?
They’re actually easier for most owners. There’s no oil change, no spark plug, and no carburetor to clean. The main upkeep is keeping the battery contacts clean, sharpening the blade once or twice a season, and storing the pack out of extreme cold.
Can a battery mower handle wet or tall grass?
Thick, damp grass puts more load on any mower, and battery models can bog down if the deck is too small for the lawn. Higher-voltage platforms (56V and 80V) like the EGO POWER+ 21in Self-Propelled LM2135SP handle tough conditions more confidently than lower-voltage picks.
What happens if I lose a battery?
Most brands sell replacements directly, and lithium packs typically last several seasons before capacity drops. Dual-battery models like the Litheli 40V 16in only run with both packs installed, so losing one stops the mower until a replacement arrives.
Is a self-propelled mower worth the extra cost?
For flat, small yards, push mowers do the job just fine. For slopes, large lawns, or anyone with mobility concerns, self-propelled drive saves real effort, which is why the EGO POWER+ bundle earns its position in this lineup.
The Takeaway
The right electric start lawn mower depends mostly on lawn size and terrain. Compact 13 and 14-inch picks like the Casince or Litheli 14in suit small urban lots, while the Litheli 40V 16in covers mid-sized yards with extended runtime. For bigger or sloped properties, the Greenworks 80V 21in, the Honda HRX-BE, or the EGO POWER+ 21in Self-Propelled LM2135SP deliver the cutting width and torque that justify their size. Pick the deck that matches the lawn, and the rest tends to fall into place.
