Cordless self-propelled mowers have quietly outgrown their gas rivals in the 21-inch class, and that’s the real story heading into the mowing season. For homeowners weighing an upgrade from a push mower or a noisy gas model, the right battery-powered machine now matches the cut quality while cutting the noise and maintenance to near zero. I narrowed the field to six standout options that balance deck size, run time, and value for typical suburban lots.
The Leading Options At A Glance
Greenworks 80V 21in Push Lawn Mower 4.0 Ah Battery
EGO POWER+ LM2135SP Self-Propelled Cordless Mower
Honda HRX-BE 21-Inch Battery Lawn Mower
Honda HRX-BV 21-Inch Battery Lawn Mower
Litheli 40V 16 Inch Cordless Brushless Mower
Litheli 14 Inch Cordless Brushless Mower
Meet The Standout Selections
The Greenworks 80V pushes into the self-propelled conversation with a steel deck (the metal housing that holds the blade) sized at 21 inches and a brushless motor, which uses electronic instead of carbon contacts, runs quieter, and typically lasts longer than brushed designs. For homeowners with half-acre lots who want a familiar walk-behind feel without gas, the 4.0Ah battery (amp-hour rating that hints at capacity) and rapid charger make weekend mowing feel simple.
Single-lever height adjustment lets you change the deck in one motion rather than tweaking four wheels. Compared with the EGO POWER+ that follows, Greenworks leans toward a more traditional push-style experience, which may appeal to anyone stepping up from a basic corded or gas mower.
A Favorable Mix
- Steel deck handles rough residential use and stays rigid over uneven ground.
- Brushless motor runs quieter and should outlast brushed alternatives under regular mowing.
- Single-lever height change saves time when switching between thick and thin patches.
- Rapid charger reaches a full charge in about 60 minutes, useful for back-to-back mows.
Trade-Offs To Consider
- Run-time varies with grass height and terrain, so thick spring growth may demand a second battery.
- Push-style handling means no self-propelled drive, which can fatigue longer cuts.
Who It Suits Best
Suburban homeowners with flat to gently sloped yards who prefer a familiar push feel with electric simplicity.
Skip It When
Sloped or large-lawn owners should reach for the EGO POWER+ LM2135SP instead, since its self-propelled drive and dual battery setup handle longer distances with less effort.
EGO built the LM2135SP around a 56V platform and a Select Cut multi-blade system, which means three interchangeable lower blades for mulching, bagging, or extended runtime. The bundle here ships with a 7.5Ah main battery, a 5.0Ah spare (sent separately), and the rapid charger, giving anyone with a half-acre-plus yard serious headroom on a single session.
Self-propelled drive takes the push out of long mows, and torque output is rated to exceed comparable gas units. Compared with the Greenworks 80V I just covered, the EGO feels more like a premium tool: faster blade swaps, stronger drive, and a wider battery ecosystem if you already own other EGO tools.
Where It Excels
- Interchangeable blades let you tune the cut to mulching, bagging, or runtime priorities.
- Self-propelled drive helps on sloped or longer-lawn sessions.
- Dual battery bundle extends runtime well past a single 7.5Ah charge.
Points To Note
- The extra battery ships in a separate package, so plan for two deliveries.
- Heavier than the Litheli 14-inch compact model that appears later, which matters for tight storage spots.

Consider Something Else When
Shoppers with very small lots may find the Litheli 14 Inch Cordless Brushless Mower easier to store and push, since its compact build wins for tight garages.
Honda brings its engine DNA into the cordless era with the HRX-BE, pairing a battery drive with the brand’s well-known Versamow system. Versamow is a 4-in-1 cutting setup (mulch, bag, discharge, leaf-shred) controlled by a single Clip Director lever, so no extra attachments or tools are needed when switching modes. For homeowners who treat mowing as lawn care, not just a chore, that flexibility is the headline.
The HRX-BE differs from the HRX-BV that follows in its drive configuration and bagging emphasis. Compared with the EGO POWER+ above, the Honda feels more traditional underfoot, trading some battery innovation for Honda-grade build quality.
Good Reasons To Consider
- Versamow 4-in-1 system handles mulch, bag, discharge, and leaf-shred in one deck.
- Clip Director lever switches modes with no tools or add-on plates.
- Honda’s reputation for long-lasting engines carries to its battery engineering.
Honest Caveats
- Battery and charger often sell separately, so factor those into total cost.
- Heavier than the compact Litheli models, which makes storing it in a small garage less convenient.
Made For
Lawn enthusiasts who want Honda reliability and versatile cutting modes without owning a gas engine.
A Better Fit Elsewhere
Anyone on a tighter budget may be happier with the Litheli 40V 16 Inch Cordless Brushless Mower, since it ships with two batteries in the box and covers most small-to-mid yards.
The HRX-BV shares the same 21-inch deck and Versamow system as the HRX-BE above, but pairs it with Honda’s twin-blade MicroCut setup, which uses four cutting edges instead of two for finer clippings and better bagging. For homeowners who bag more than they mulch, this configuration produces noticeably smaller clippings that pack tighter.
Honda’s battery motor holds RPMs (revolutions per minute) under load, a trait borrowed from its gas GCV engines, so thick St. Augustine or fescue patches are less likely to stall the blade. That consistency matters more than headline torque for many buyers.
Where It Delivers
- Twin MicroCut blades leave finer clippings for cleaner bagging and faster decomposition.
- Versamow Clip Director handles four cutting modes without extra attachments.
- Stable RPM under load matches Honda gas-engine behavior in tough grass.
Small Caveats
- Like the HRX-BE, the battery is often a separate purchase, raising the entry cost.
- Premium pricing versus the Litheli pair means budget-focused shoppers should weigh value.
Quick Facts
Best Suited To
Homeowners with thick or premium turf who want a Honda-grade battery mower with refined cut quality.
Reach For A Different Pick When
First-time battery buyers may prefer the EGO POWER+ LM2135SP, which ships with batteries and a charger included in the main bundle.
Litheli’s 40V 16-inch model leans into the mid-size category with a dual-battery setup, meaning both 5.0Ah packs must be inserted to hit full 40V output. The trade-off is consistent power across the deck, no sag as one battery drains mid-mow. Six height adjustments from 25mm to 75mm cover most turf types, from low-cut zoysia to taller cool-season grass.
The 50L collection bag holds plenty of clippings, and mulching mode uses the same deck with the bag removed. Versus the Honda HRX-BV covered earlier, the Litheli gives up deck width and refinement for a friendlier price and simpler maintenance.
The Case For It
- Two included 5.0Ah batteries mean no extra accessory purchases up front.
- Brushless motor needs no oil, spark plug, or carburetor service.
- Six cutting heights from 25 to 75mm cover nearly any residential turf type.
Worth Bearing In Mind
- 16-inch deck means more passes than the 21-inch Honda or Greenworks picks.
- Both batteries must be installed to unlock full 40V output, so you cannot run on one in a pinch.
Right Fit For
Mid-size-lot homeowners who want dual-battery runtime and minimal maintenance without paying premium-brand prices.
Where Another Pick Suits Better
Owners with expansive lawns will be happier with the Greenworks 80V 21in Push Lawn Mower, since its wider deck trims mowing time on bigger areas.
The 14-inch Litheli is the compact pick in this roundup, sized for small lawns and tight storage. Its brushless motor keeps weight low, and the 5.0Ah battery delivers enough runtime to cut roughly 3,000 square feet per charge, which covers most city-sized yards. The adjustable handle and quick-fold frame also make it a friendly option for seniors or anyone who wants a lighter carry from shed to lawn.
Five height positions, ranging from 1 to 2.5 inches, give a reasonable cut range without the six-step adjustment of the larger Litheli above. Against the EGO POWER+ and Honda models in this list, the 14-inch Litheli trades deck width and drive for portability and price.
Everyday Advantages
- Compact 14-inch deck slips through shed doors and narrow side yards with ease.
- Brushless motor cuts noise, which matters for early-morning or evening mowing in dense neighborhoods.
- Quick-fold handle shrinks the footprint for apartment balconies and small garages.
Some Limits To Know
- 14-inch deck means noticeably more passes than the 21-inch Honda HRX-BV or EGO POWER+.
- Coverage tops out around 3,000 square feet, so larger lots will need multiple charges.

Swap It Out When
Anyone with a yard larger than a quarter-acre should reach for the Litheli 40V 16 Inch Cordless Brushless Mower, since its wider deck and dual batteries shorten mowing time.
What To Weigh Before Choosing Your Next Mower
Deck Size And Yard Scale
A 21-inch deck covers more ground per pass, which matters for half-acre lots and longer mowing sessions. Smaller 14- to 16-inch decks are easier to push and store, but they demand more passes on bigger yards. Match the deck to your lawn footprint rather than chasing the widest option.
Battery Voltage And Runtime
Voltage (the battery’s electrical pressure) drives torque, while amp-hours (Ah) drive runtime. A 56V or 80V platform handles thick grass and slopes better than a 40V system, but the higher-voltage models cost more. For flat suburban lawns under a quarter acre, 40V is often plenty.
Drive Type And Ergonomics
Self-propelled drive reduces fatigue on hills and large lawns, and it shows up on the EGO POWER+ LM2135SP in this list. Push mowers, like the Greenworks 80V, stay lighter and simpler but require more effort. Adjustable, folding handles add comfort for shorter or older operators.
Cut Modes And Finish Quality
4-in-1 Versamow systems (Honda HRX-BE and HRX-BV) handle mulching, bagging, discharge, and leaf shredding with one deck. Multi-blade systems (EGO Select Cut) let you swap blade styles instead. Pick the system that matches how you handle clippings.
Key Considerations Across These Picks
Common Shopping Slip Ups
Battery and charger bundles vary wildly between models. Some mowers, like the Honda HRX-BE and HRX-BV, often list the deck only, leaving the battery as a separate purchase. Always check whether the listing includes a battery and charger, or budget for them separately.
Another slip is matching deck size to storage rather than yard size. A 21-inch mower is useless if it does not fit your shed, but a 14-inch deck will frustrate you on a half-acre lawn. Measure both before ordering.
Where The Extra Money Goes
Premium models like the Honda HRX pair and the EGO POWER+ LM2135SP earn their higher cost through stronger motors, self-propelled drive, and refined cut systems. For large, sloped, or thick-turf lawns, that extra money translates to less fatigue and a cleaner finish. For small, flat lawns, a Litheli or Greenworks model covers the job without the premium.
Frequently Asked Questions
How long does a battery mower actually run?
Most cordless mowers in this 21-inch self-propelled class deliver 30 to 60 minutes of runtime per charge, depending on grass thickness and whether you use self-propelled drive. Dual-battery bundles stretch that further.
Can a cordless mower handle wet grass?
Cutting very wet grass is not recommended for any mower, gas or electric. Wet clippings clump, clog the deck, and strain the motor. For thick or damp conditions, slow your pace and mow in shorter passes.
Are brushless motors worth it?
Yes, in most cases. Brushless motors are more efficient, run cooler, and typically last longer than brushed designs. They also tend to be quieter, which is a real plus in suburban neighborhoods.
Do self-propelled mowers work on hills?
They help a lot. The drive system takes over much of the pushing effort, leaving you to steer rather than muscle the mower uphill. For steep slopes, pair self-propelled drive with a higher-voltage battery for the best results.
How do I store a battery mower long-term?
Remove the battery and store it indoors at room temperature. Fold the handle if the model supports it, and keep the deck clean and dry to prevent corrosion. A quick wipe-down after each mow goes a long way.
Bottom Line
Cordless self-propelled mowers have matured into real substitutes for gas, and the six picks above cover everything from a 14-inch compact to a 21-inch Honda-grade workhorse. Start with your yard size and terrain, then narrow down by deck width, drive type, and battery bundle. The right match makes weekend mowing quieter, cleaner, and far less of a chore.
