Battery-powered walk-behinds have quietly taken over suburban lawns. You skip the gas can, the oil checks, and the pull-cord battle, and you trade ear-splitting engine drone for the gentle whine of a brushless motor. For anyone juggling a quarter-acre to a full acre of turf, these machines deliver gas-like cutting without the Saturday-morning wake-up call for the neighbors.
The Picks In Brief

More On The Choices That Made The List
The flagship 80V platform from Greenworks aims squarely at homeowners who used to rely on a gas mower and don’t want to feel like they downgraded. The brushless motor is the headline here, a design with no carbon brushes to wear down, so it runs cooler, lasts longer, and squeezes more cutting power out of each battery amp-hour than older brushed designs could. Paired with a self-propelled rear-wheel drive, it pulls itself up modest slopes without you shoving, which matters more than spec sheets suggest on a humid July afternoon.
The 21-inch steel deck covers ground quickly on open lawns, and a 4.0 Ah battery ships in the box so you can mow out of the gate. If you’ve been nursing a temperamental gas engine for years, this is the kind of step-up that genuinely changes the chore.
Strong Points
- Brushless motor delivers high torque for tall, thick, or slightly damp grass without bogging down.
- Self-propelled rear-wheel drive takes strain off your hips on slopes and longer passes.
- 80V battery platform shares across more than 50 Greenworks tools, handy if you already own their blower or trimmer.
- 21-inch cutting deck trims mowing time versus narrower 17-inch or 19-inch walk-behinds.
- Full kit includes the battery and charger, so you’re not scrambling for extras on day one.
Things To Consider
- Heavier than the 17-inch push model below, which you’ll feel when storing it in a tight garage corner.
- For lawns pushing two acres, you may need a second battery on hand to finish without a charging break.
Who It Suits Best
Homeowners with lawns up to roughly three-quarters of an acre who want gas-tier cutting strength without the maintenance.
Consider Something Else When
If your yard is half an acre or smaller and you want the lightest mower on this list, the Greenworks 60V 17in Push Lawn Mower is a friendlier fit.
Where the 80V model above flexes raw torque, the 60V sibling leans into endurance. This kit ships with two 4.0 Ah batteries rather than one, which quietly doubles your effective runtime and lets you swap packs mid-cut on bigger yards without hauling the whole mower back to the outlet. The brushless motor still spins at a brisk 3,200 RPM at the blade, so cut quality stays consistent rather than tapering off as the battery drains.
Owners typically cite the noticeably quieter operation compared to gas mowers, a real benefit in neighborhoods with early start-time norms. You trade a touch of peak torque against the 80V unit, but for most suburban grass, that gap rarely shows up.
Useful Touches
- Two batteries in the box effectively extend runtime, ideal for half-acre to three-quarter-acre lawns.
- Brushless motor reaches 3,200 RPM, holding blade speed steady as the charge drops.
- Quieter than comparable gas walk-behinds, helpful in close-set neighborhoods.
- Self-propelled drive reduces fatigue on uneven ground or mild inclines.
Worth Noting
- Carrying two batteries around adds storage weight if your shed space is already tight.
- Not as torquey as the 80V pick when grass gets tall and wet after a rain delay.
- Battery care matters: storing them through winter at partial charge extends their service life.
Made For
Suburban households with a half-acre lot who want backup battery capacity included from day one.
Look Elsewhere When
If your yard is small and storage space is precious, the Worx Cordless Lawn Mower WG752 has a more compact footprint with similar cutting width.
This is the same 80V self-propelled deck you saw in pick #1, stripped down to the bare tool. The “MO80L00” suffix tells you nothing in the box beyond the mower itself, no battery, no charger, nothing. For anyone already running a fleet of Greenworks 80V tools, that’s actually the whole point: skip paying for a battery you already own and pour the savings into other gear.
Up to 60 minutes of runtime with a fully charged 5.0 Ah battery covers most suburban lots, and the deck handles up to an acre on a charge. Just make sure you actually have an 80V pack on the shelf before adding this to your cart.
The Good Stuff
- Tool-only pricing undercuts the kit version, smart savings for existing 80V owners.
- Rated for up to 60 minutes of runtime with a 5.0 Ah battery, plenty for typical suburban lots.
- Self-propelled drive with a 21-inch deck keeps mowing sessions efficient.
- Plays nicely with the broader 80V ecosystem spanning more than 50 tools.
Points To Note
- No battery or charger included, so the out-of-pocket total climbs if you’re starting fresh.
- Brush wear and blade sharpening are the only routine jobs, though blade checks each season keep cut quality high.
Best Suited To
Existing Greenworks 80V households expanding their mower lineup without duplicating batteries.
Swap It Out When
If you don’t already own an 80V battery, the Greenworks 80V 21in Self-Propelled Lawn Mower in pick #1 is the smarter buy since it ships with everything.
Worx takes a different swing with the Nitro 40V platform: same 21-inch deck width as the Greenworks picks, but at a lower voltage that trades absolute power for lighter handling. The headline feature is the aerodeck cutting system, where the deck’s internal airflow is tuned to lift grass blades evenly before the blade hits them. The result is a cleaner cut at taller heights and noticeably better bagging performance when leaves start dropping in October.
For households that mow weekly through summer and bag more than they mulch, that airflow detail genuinely matters. Add the 3-in-1 capability (bag, mulch, or side discharge) and you’ve got a flexible weekend workhorse.
The Upside
- Aerodeck airflow lifts grass for a more even cut and stronger bagging on leaf-heavy lawns.
- 3-in-1 design switches between bagging, mulching, and side discharge without tools.
- Rated for lawns up to half an acre, a common suburban sweet spot.
- Lighter than the 80V self-propelled units, easier to maneuver around playground equipment.
Honest Caveats
- 40V platform offers less torque than the 60V and 80V picks when grass gets tall after a vacation.
- Shared 20V/40V Worx battery ecosystem is less mature than Greenworks’ 80V lineup, which limits future expansion.
Who Should Grab It
Family households with a half-acre lot who mow on a regular schedule and want easy switching between bag and mulch modes.
A Better Fit Elsewhere
If your lawn stretches past three-quarters of an acre, the Greenworks 60V 21in Self-Propelled Mower Kit from pick #2 has the battery capacity to finish without a pause.
The smallest deck in this roundup belongs to a 17-inch push mower that fills a very specific niche. Narrow side-yard strips, postage-stamp lawns behind a townhouse, or tight passages between raised garden beds all favor a slimmer deck over a wide one. Without the self-propelled drive system, the overall weight drops meaningfully, which matters when you’re carrying it up a basement stairwell or sliding it into a shallow shed.
The 60V brushless motor still delivers genuine cutting strength, and a 4.0 Ah battery ships in the box. For small lots, it’s hard to argue with less mower for less money.
A Strong Showing
- 17-inch deck slips through 30-inch gates and narrow side-yard corridors easily.
- 60V brushless motor handles typical bluegrass and fescue without complaint.
- Push design cuts weight, easier for smaller-framed operators or anyone carrying it up stairs.
- Full kit ships with battery and charger, ready to use from the box.
A Few Limitations
- No self-propelled drive means you provide all the push on sloped ground.
- Smaller deck means more passes on any lawn over a third of an acre, cutting time climbs fast.
Whose Yard It Belongs On
Condo, townhome, or small suburban yard owners who store equipment in a closet or shallow shed and rarely mow more than a quarter acre.
Reach For A Different Pick When
If your yard is bigger than a third of an acre, the Greenworks 80V 21in Self-Propelled Lawn Mower from pick #1 will save you real time per cut.
What Matters Most When Buying A Cordless Self-Propelled Mower
Battery voltage sets the tone for the entire machine. Higher voltage platforms (60V, 80V) deliver more torque for thick grass and steep slopes, while lower voltage (40V) systems trade some cutting muscle for lighter weight and easier handling. The trade-off matters most when your mowing day involves tall grass after a wet stretch or a hill that makes your calves complain.
Deck width changes how fast you finish. A 21-inch deck covers more ground per pass, which matters on open lots, but a 17-inch deck handles narrow gates and tight landscaping better. Think about the narrowest passage you’ll push through before you fall in love with a wider model.
Runtime is battery capacity multiplied by motor efficiency. A 4.0 Ah pack typically delivers 30 to 45 minutes of mowing depending on grass height and terrain. Two batteries in the kit, like the 60V model above, effectively doubles your working window without waiting for a recharge. Storage also belongs in the conversation: batteries prefer a cool, dry spot at partial charge during winter months.
Picking The Right Mower Without The Regret
Where Shoppers Go Wrong
Treating voltage as the only spec. Two 60V mowers can perform very differently depending on motor design and deck construction. Look at how the mower handles wet grass and slopes, not just the number on the battery. Also, measure your narrowest gate before buying a wide deck, because a 21-inch mower that won’t fit through your backyard fence becomes an expensive shelf ornament.
When Paying More Pays Off
Premium tiers typically add brushless motors, larger batteries, and self-propelled drive systems. The motor upgrade alone extends service life substantially over brushed designs, the battery upgrade eliminates mid-cut charging breaks, and the drive system reduces fatigue on sloped ground. If your lawn pushes past a half acre or includes any meaningful incline, the jump to a higher tier tends to pay you back in saved effort every single weekend.
