Cordless mowers have quietly outgrown their early reputation. Battery voltage climbs, deck sizes match gas, and run-time now covers a standard suburban lot on one charge. The result: less noise, no fuel spills, and zero engine winterization. You still need to pick a model that matches your lawn’s size, terrain, and your tolerance for pushing versus self-propelled drive.
A Quick View Of The Lineup
Greenworks 80V 21in Push Lawn Mower 4.0 Ah
EGO POWER+ LM2135SP Self-Propelled Mower
Honda HRX-BE 21-Inch Battery Mower
Honda HRX-BV 21-Inch Battery Mower
A Closer Look At Each Pick
The Greenworks 80V lands in that comfortable middle ground where battery power, deck size, and price stop fighting each other. A 21-inch cutting width suits most suburban lots up to about a third of an acre, and the 80-volt platform delivers noticeably more torque than the 40V systems in the brand’s smaller lineup. You push it yourself, which keeps the build lighter and the controls simpler than the self-propelled options further down this list.
A brushless motor handles the hard work quietly, with less heat buildup than brushed designs tend to generate over a season. You get up to roughly 60 minutes of run-time on the included 4.0Ah battery, though thick spring grass, wet conditions, or aggressive bagging will pull that number lower. The single-lever height adjustment means you set all four wheels at once, which sounds minor until you’ve moved a mower between eight height positions one wheel at a time.
Useful Touches
- 80V battery platform runs cooler and lasts longer per charge than lower-voltage walk-behinds.
- 21-inch steel deck covers more ground per pass, so the typical front yard finishes in fewer laps.
- Brushless motor reduces wear, so the internal components tend to outlast brushed designs.
- Single-lever height adjustment speeds up spring and fall cut changes.
- Push design keeps weight low, making tight storage in a shed or garage easier.
Things To Consider
- No self-propelled drive, so steep or uneven terrain gets tiring over a long mow.
- Roughly 60 minutes of run-time falls short for larger lots, where an extra battery or a different model is a better fit.
- Steel deck resists dings well but adds weight compared to composite decks on lighter mowers.
Made For
Homeowners with a flat, medium-size yard who want a no-fuss cordless upgrade and don’t mind putting in some pushing.
Consider Something Else When
The EGO POWER+ LM2135SP suits shoppers on a sloped lot or anyone who would rather let the mower drive itself through long sessions.
EGO’s LM2135SP is the kind of mower that resets what cordless can do. The 56V battery platform pushes output up to roughly 7.0 ft-lbs of torque, which lands well above what most 40V mowers manage. Unlike the Greenworks push model above, this one drives itself at the speed you set, which is the difference between a casual Saturday chore and a sweat-drenched workout on a long, hilly lot.
The Select Cut Multi-Blade system swaps between mulching, high-lift bagging, and extended-run-time blades depending on the day, and an extra 5.0Ah battery ships in the bundle so you can hot-swap for bigger properties. A 7.5Ah pack handles most lawns up to three-quarters of an acre, and the rapid charger trims downtime. The trade-off is weight and price, both noticeably higher than the Greenworks entry above.
What Makes Sense
- Self-propelled drive softens hills, so steep or uneven yards become practical rather than punishing.
- Select Cut blade system adapts to mulching, bagging, or extended runtime in one mower.
- Dual-battery bundle keeps larger lots manageable without long charging pauses.
Trade Offs
- Higher cost than push mowers, with a steeper starting investment before any accessories.
- Heavier chassis can make storage in tight shed corners awkward.

Who Will Love This
Owners with a larger or sloped lot who want gas-like cutting performance without engine maintenance.
Skip It When
The Greenworks 80V is a smarter pick for small, flat lawns where self-propelled drive adds cost without earning its keep.
The HRX-BE carries Honda’s reputation for cut quality into the battery world. Honda positions the motor’s torque against its own GCV gas engine lineage, and the result holds up well in thick or tall grass. The Versamow system with Clip Director is the headline feature, letting you switch between mulching, bagging, discharge, and leaf shredding without swapping parts. That kind of in-mower mode shifting is rare in the cordless category.
Compare it to the EGO above and the HRX-BE leans more toward cut refinement than raw runtime. The HRX-BE is electric-start, which simplifies ignition, though run-time depends heavily on the battery configuration and grass density. The 21-inch deck still matches the Greenworks and EGO, so pass coverage stays consistent across the four-pick lineup.
Useful Strengths
- Versamow 4-in-1 with Clip Director handles mulch, bag, discharge, and leaf shred in one deck.
- Honda motor design prioritizes consistent RPM under load, which helps in dense patches.
- Electric start removes pull-cord effort on cold mornings.
Room For Improvement
- Higher price tag than the Greenworks or basic EGO models in this category.
- Available battery capacity for this trim level tends to run smaller than the EGO bundle option.
Right Fit For
Shoppers who want a single mower to handle bagging, mulching, and leaf season without juggling attachments.
Swap It Out When
The EGO POWER+ LM2135SP is the better match for very large lots where a second battery and self-propelled drive matter more than cut-mode flexibility.
The HRX-BV slots in as the BV variant of Honda’s HRX battery walk-behind, and the headline change is the inclusion of Versamow with the Clip Director for on-the-fly mode control. Honda’s motor engineering is the real draw here, since the brand is known for keeping RPMs stable even in taller grass. This model suits shoppers who like the engineering pedigree of the HRX line and want the added BV trim features.
It shares a 21-inch deck and Versamow 4-in-1 system with the HRX-BE above, so the cutting experience feels familiar. Where the two diverge is in the trim configuration and price tier, so the HRX-BV makes sense for shoppers specifically shopping the BV variant. If raw runtime is the deciding factor, the EGO bundle earlier in the lineup still offers more total amp-hours out of the box.
Useful Highlights
- Versamow with Clip Director lets you shift between mulching, bagging, and discharge without tools.
- Honda’s GCV-derived motor platform prioritizes high torque output under load.
- 21-inch deck matches the rest of the lineup, so cut quality stays consistent across brands.
Points To Note
- BV trim pricing can run higher than the BE variant, which offers similar deck and motor core features.
- Runtime depends on the battery pack selected, and the heaviest loads may require a second battery.
- Brand-specific batteries and chargers tend to be pricier than universal options, an ownership cost worth factoring in.
Who Should Grab It
Honda loyalists who want the BV variant specifically, and who value Versamow mode switching in a battery platform.
Look Elsewhere When
The Greenworks 80V is a stronger fit for shoppers focused on value and a flat, smaller lawn where Honda’s premium features go unused.
What To Weigh Before Picking A Cordless Mower
Match The Battery To Your Lot Size
Run-time claims depend on the Ah rating of the battery pack, where higher Ah means longer mowing before a recharge. A 4.0Ah pack works for small to medium lots, while 7.5Ah or dual-battery setups stretch into three-quarter-acre territory. Walk your lot first, note obstacles, and pick a battery size that handles it with a comfortable margin.
Push Versus Self-Propelled Drive
Push mowers cost less and weigh less, which makes them easier to store and lighter to maneuver. Self-propelled mowers take the strain off on hills and long passes, but they cost more and add weight. The honest read is that flat lots rarely justify self-propelled drive, while anything sloped or longer than a quarter acre usually does.
Deck Material And Cut Modes
Steel decks absorb dings and last longer; composite decks cut weight and resist rust. Cut modes matter for seasonal flexibility: mulching in spring, bagging during peak growth, and leaf shredding in fall. Models like the Honda HRX pair these modes into one Versamow system, which simplifies the workflow for homeowners who mow in different modes year-round.
Voltage, Torque, And Real Grass
Higher voltage generally means stronger torque, which is the force that keeps the blade turning in tall, wet, or thick grass. A 40V system handles light suburban lawns; 56V to 80V platforms perform closer to gas in tougher conditions. Picking the right voltage depends less on marketing and more on what your grass actually does in June.
Key Considerations Across These Picks
Where Shoppers Go Wrong
Buyers often chase the largest deck without checking the battery capacity that supports it. A wide deck with a small battery means stopping mid-yard for a recharge. Storage size, terrain slope, and seasonal leaf volume all matter as much as the headline features.
What The Higher Tier Buys
Spending more on a model like the EGO POWER+ LM2135SP or the Honda HRX-BV usually buys self-propelled drive, larger battery bundles, and multi-mode cutting systems. The upgrade pays off for larger lots, sloped terrain, and homeowners who want one mower to handle bagging, mulching, and leaf cleanup without swapping parts. For a flat quarter-acre lot, the lower tiers cover the job without the extra cost.
Frequently Asked Questions
How long does a cordless lawnmower typically run on a single charge?
Run-time varies with battery capacity and grass conditions, but most 4.0 to 7.5Ah packs deliver somewhere between 30 and 60 minutes of mowing. Thicker grass, wet lawns, and bagging all reduce that window.
Can a battery mower handle thick or wet grass?
Higher-voltage platforms with strong torque, such as 56V and 80V systems, manage thick grass well in typical conditions. Very wet or overgrown lawns still tax any cordless mower, so mowing frequency matters as much as voltage.
Are cordless mowers powerful enough for large yards?
Larger yards work best with self-propelled models and dual-battery bundles, since you can swap packs without a long charging pause. A single 4.0Ah battery is usually better suited to small or medium lots.
How long do lithium-ion mower batteries last?
Most lithium-ion mower batteries hold useful capacity for around three to five seasons of regular use. Storage temperature and charge habits affect lifespan, so keeping packs in a climate-controlled shed in winter helps.
Is a self-propelled mower worth the extra cost?
Self-propelled drive earns its price on sloped or longer mowing sessions, where the effort saved adds up over a season. For a small, flat yard, a push mower is usually enough and easier to store.
Final Verdict
The right cordless mower depends on lot size, terrain, and how you like to mow. The Greenworks 80V covers flat, medium-size yards with a simple, capable package. The EGO POWER+ LM2135SP stretches into larger and sloped territory with self-propelled drive and a dual-battery bundle. The Honda HRX-BE and HRX-BV bring Versamow mode switching for homeowners who want one mower for every season. Match the platform to your lawn, and the rest falls into place.
