Going electric on the lawn used to mean compromises. Today’s cordless walk-behinds and self-propelled mowers have closed the gap with gas models, and for most suburban yards, they deliver the cut, torque, and runtime that matter without the noise, oil, or exhaust. I wrote this roundup for homeowners who want cleaner, quieter weekend mowing and a real sense of which machine fits their lawn, their strength, and their tolerance for recharging mid-cut.
The Shortlist At A Glance
Greenworks 80V 21in Push Lawn Mower, 4.0Ah Battery & Charger
Casince 17in Cordless Walk Behind Lawn Mower
EGO POWER+ LM2135SP Self-Propelled Mower w/ 7.5Ah + 5Ah Batteries
KraftSense 40V 21in Cordless Lawn Mower w/ Dual 4.0Ah Batteries
Honda HRX-BE 21in Battery Walk Behind Mower (HRX217YXBEXA6)
A Deeper Look At The Lineup
The Greenworks 80V pushes the brand into serious cutting territory. A 21-inch steel deck handles a wide swath per pass, and the brushless motor (a motor design that uses electronic controllers instead of carbon brushes, reducing friction and wear) gives it the kind of torque that pulls through thicker patches without bogging. For most homeowners with a quarter-acre lot, this is the sweet spot between capability and simplicity.
Unlike the Casince 17-inch walk-behind reviewed next, this Greenworks model gives up a bit of maneuverability in exchange for fewer passes. It’s a push mower, so hills demand legwork, but the included 4.0Ah battery and 60-minute rapid charger cover a typical suburban mow without a battery swap.
Real Benefits
- Up to about 60 minutes of runtime per charge, enough for most mid-size lawns on a single battery
- Brushless motor runs quieter than brushed alternatives and typically outlasts them
- Single-lever height adjustment lets you change all four wheels at once instead of crouching four times
- Steel deck holds up to bumps and curbs better than the plastic shells on budget models
- 80V platform shares batteries across the Greenworks tool family if you already own one
Things To Consider
- Push-only design means slopes will tax your legs on larger properties
- Run-time varies with grass length and thickness, so overgrown lawns may need a second battery
- Steel deck adds weight, which is great for stability but harder to lift into a shed
Feature Snapshot
Right Fit For
Homeowners with flat to gently sloping lawns under a half acre who want a no-fuss push mower with enough voltage to handle real grass.
Swap It Out When
Steep hills or long mowing distances point to the EGO POWER+ LM2135SP self-propelled mower, which drives itself and saves your legs.
Small yards reward small mowers. The Casince 17-inch deck slips between garden beds and around tight corners where a 21-inch machine would chew up flower borders. Two 20V 4.0Ah batteries run in series to deliver 40V of cutting power, and six height positions from roughly 1 to 3 inches cover most lawn preferences.
Compared to the Greenworks above, this Casince trades raw deck size for agility and a smaller storage footprint. For a townhouse lawn, an urban courtyard, or a postage-stamp backyard, that’s a worthwhile trade.
Practical Pluses
- 17-inch deck fits through narrow gates and stores in tight sheds
- Dual 4.0Ah batteries extend runtime and let you hot-swap if one runs dry
- Six height settings give finer control than three-position mowers
- Lighter overall weight makes it manageable for most users to carry or lift
Points To Note
- Smaller deck means more passes on anything over a small yard
- Dual 20V batteries add complexity when tracking charge levels
- Best suited to thin or average grass; heavy growth will drain the pack quickly
Made For
Small-lawn owners who value maneuverability and easy storage over wide-deck efficiency, especially in fenced yards with narrow access.
Look Elsewhere When
Anyone mowing a quarter acre or more will save time with the wider Greenworks 80V 21-inch model.
EGO’s LM2135SP is the first mower in this lineup that drives itself, which sounds small until you’ve pushed a heavy machine up a wet slope. The 56V platform pushes genuine torque, and the Select Cut multi-blade system lets you swap lower blades for mulching, bagging, or extended runtime without changing the whole deck.
Where the Greenworks 80V and KraftSense below are walk-and-push designs, this EGO has a drive motor in the rear wheels. The included 7.5Ah battery covers most cuts, and the bundled 5.0Ah pack extends range or backs up the primary on a long mow.
The Value In It
- Self-propelled drive removes most of the physical effort on slopes
- Select Cut blades let you optimize for finish, bagging, or runtime without buying extras
- Two batteries in the bundle mean you can mow and charge in rotation
- 56V architecture rivals small gas engines in real cutting torque
Trade Offs
- Self-propelled units weigh more and cost more than equivalent push mowers
- Extra battery takes up storage space and needs its own charging slot
- Multiple blade options add a small learning curve for first-time owners
Quick Technical Notes
Who Should Grab It
Homeowners with sloped, uneven, or simply larger lawns who want a self-propelled drive and the option to swap blade styles mid-season.
A Better Fit Elsewhere
Flat small yards under a quarter acre don’t need the self-propelled drive; the Greenworks 80V push mower gets the same 21-inch job done for less.
Quiet operation is the headline feature here, and on early Sunday mornings that matters more than most spec sheets admit. The KraftSense 40V runs two 4.0Ah batteries in parallel for up to 40 minutes of runtime, and the brushless motor stays notably hushed compared to gas. The 21-inch deck puts it in the same width class as the Greenworks 80V.
Against the EGO self-propelled unit above, this KraftSense is lighter and simpler, but you give up drive assist. It’s a push mower for someone who values a quieter neighborhood footprint.
Where It Excels
- Brushless motor keeps noise low enough for early-morning mowing without complaints
- Dual 4.0Ah packs cover roughly a quarter acre per charge under typical conditions
- 21-inch deck matches the width of bigger-name competitors
- Brushless design avoids the carbon-brush wear that shortens brushed-motor life
Honest Caveats
- 40V platform has less torque than the 56V or 80V options in thicker grass
- Push-only design, so slopes still demand leg power
- Newer brand presence means replacement batteries and parts may take longer to source

Whose Shelf It Belongs On
Noise-conscious homeowners in close-set neighborhoods who want a wide deck without the roar of gas.
Consider Something Else When
Thick or wet grass and steep terrain push the KraftSense toward its limits; the EGO POWER+ LM2135SP handles both better.
Honda’s battery walk-behind leans on the brand’s engine-building heritage. The HRX-BE pairs a Honda-built electric motor with the GCV-series gas-equivalent torque curve, which means RPMs hold steady when the grass gets thick. The 4-in-1 Versamow system with Clip Director switches between mulching, bagging, discharge, and leaf shred without extra attachments.
Compared to the rest of this list, the HRX-BE is the most demanding in build quality and the most flexible in cut style. It’s also a Honda, and that lineage tends to matter to people who’ve owned Honda gas mowers for decades.
Everyday Advantages
- Honda’s motor design maintains cutting RPM under load better than many competitors
- Versamow Clip Director toggles between four cut modes with a single lever
- Twin MicroCut blades (two stacked blades that cut clippings finer than a single blade) deliver a finer mulch and bag finish
- Brand reputation for longevity carries over from Honda’s gas mower line
Room For Improvement
- Premium positioning puts the HRX-BE above most battery competitors on cost
- Battery specs and runtime details vary by configuration, so check the listing carefully
- Heavier than typical plastic-deck electrics, which complicates lifting into a vehicle
Perfect Match For
Owners who want Honda build quality, mulching flexibility, and a refined cut, and who don’t mind paying a premium for it.
Reach For A Different Pick When
Budget-first shoppers get most of what they need from the Greenworks 80V or KraftSense 40V at a lower spend.
What Matters Most Before Choosing Riding Electric Lawn Mowers
Deck Size And Yard Coverage
The cutting deck is the metal housing that holds the blade. A wider deck covers more grass per pass, so 21-inch models finish a typical suburban yard faster than 17-inch units. For yards under 1,500 square feet, a compact 17-inch deck like the Casince saves time on storage and tight turns. Anything over a quarter acre benefits from sticking to 21-inch options.
Voltage, Batteries, And Runtime
Voltage (V) is the electrical “pressure” pushing power from the battery to the motor; higher voltage generally means more torque. A 40V platform like the KraftSense handles average grass with ease, while 56V and 80V systems pull through thicker growth with less bog-down. Dual-battery setups extend runtime by sharing the load or letting you hot-swap (replace a depleted battery with a charged one without powering down). Real-world runtime always depends on grass length, moisture, and terrain.
Push Versus Self-Propelled
A push mower relies entirely on your legs, which works on flat ground but taxes you on slopes. Self-propelled mowers have a drive motor in the wheels, so the machine moves forward under its own power. For hilly lots or anyone who mows frequently, the self-propelled EGO LM2135SP justifies its extra weight and cost.
Noise And Neighborhood Etiquette
Brushless motors (motors that use electronic controllers instead of physical carbon brushes to deliver current to the rotor) run quieter than brushed designs, and battery power is naturally quieter than gas. The KraftSense leans into that with its ultra-quiet claim, which matters in close-set neighborhoods where early-morning mowing can become a complaint.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
The most common mistake is choosing by deck size alone. A 21-inch mower on a tiny fenced yard with narrow gates just won’t fit, and a 17-inch deck on a half-acre lot will drain you with endless passes. Match the mower to your actual lawn size, your gates, and your storage space before falling for a wide deck.
Why Top Tier Costs More
Premium-tier mowers like the Honda HRX-BE charge more because of build quality, motor engineering, and multi-mode cutting systems. You pay for steadier RPMs under load, finer mulching, and longer service life. For most homeowners, mid-tier picks like the Greenworks 80V and KraftSense 40V cover the practical needs, while the Honda earns its place when cut quality and longevity lead the priority list.
Frequently Asked Questions
How long do cordless lawn mower batteries actually last per charge?
Most cordless mower batteries in this list run between 30 and 60 minutes per charge under typical mowing conditions, with thick or wet grass cutting that number down. Dual-battery systems stretch range by sharing the load.
Can I replace the battery later if it wears out?
Yes, every mower here uses a removable battery pack that can be replaced independently of the mower itself. Replacement batteries are widely available through the manufacturer and authorized resellers.
Are brushless motors really worth the extra cost?
For most owners, yes. Brushless motors generate less heat, run more efficiently, and typically last longer than brushed designs. They also tend to be quieter, which matters during early-morning sessions.
Will a battery mower handle thick or wet grass?
Within reason, yes. Higher-voltage platforms like the 56V EGO and 80V Greenworks handle thicker growth better than 40V models. Very wet grass still challenges any mower, electric or gas.
How do I store a cordless mower over winter?
Bring the battery indoors to a temperate spot, give the deck a thorough clean, and store the mower itself in a dry shed or garage. Cold temperatures shorten battery life if left in an unheated space.
Closing Remarks
Any of these five picks will quiet down your weekend routine and skip the gas station. Match the mower to your lawn size, your terrain, and how much effort you want to put in, and the rest takes care of itself. The right electric mower turns a chore into a quick, clean loop around the yard, and that’s the real win.
