I remember the Saturday morning my gas mower refused to start, and the quiet relief of pulling a battery instead. Cordless mowers have grown up since then, and the 80V class sits right in the sweet spot for suburban lots: enough voltage to handle thick St. Augustine, no fumes in the garage, and noticeably less noise. I put this list together for homeowners weighing a switch, for parents tired of weekend mower drama, and for anyone who just wants a clean cut without the maintenance ritual.
The Essentials At A Glance
Greenworks 80V 21in Push Lawn Mower, 4.0 Ah Battery
GREENWORKS 24V 8-Tool Combo Kit
Greenworks 60V 21in Self-Propelled Mower
Greenworks Pro 80V 21in Push Mower
Greenworks 40V 16in Push Lawn Mower
More Details On Our Top Picks
The Greenworks 80V 21in Push Lawn Mower lands at the top of my list because it threads a sensible needle between cutting width and battery weight. The 21-inch steel deck handles a typical quarter-acre lot without feeling like you’re pushing a cart, while the brushless motor, a motor design that uses electronic switching instead of carbon brushes to reduce wear and noise, delivers more torque and a longer service life than older brushed designs.
Single-lever height adjustment (a feature that lets you move all four wheels up or down with one motion) means no fiddling with four separate axles when you want a tighter cut for the front and a longer cut for the back. Owners already invested in the Greenworks 80V platform can swap batteries between tools, which makes this a natural anchor mower.
Where It Delivers
- Up to about 60 minutes of runtime on the included 4.0Ah battery, enough for most half-acre cuts in one pass
- Rapid charger refills the pack in roughly 60 minutes, so a lunch break gets you back to mowing
- Brushless motor runs quieter than gas and tends to last longer with no brushes to replace
- Steel deck handles accidental curb scrapes better than plastic alternatives
- Push design keeps weight and cost down compared to self-propelled models
Trade Offs
- No self-propulsion, so sloped lawns require more leg effort
- Runtime drops noticeably in dense, wet grass, a commonly reported behavior across cordless mowers
- Steel deck adds weight versus plastic-deck competitors if you haul it up stairs
Key Specs
Who Should Grab It
Homeowners with flat-to-gently-sloped lawns up to about a third of an acre who already want a quiet, gas-free Saturday.
Look Elsewhere When
The Greenworks 60V 21in Self-Propelled Mower suits shoppers with steeper grades who need the drive wheels to do the pushing.
I want to flag something honestly: this Greenworks 24V combo is not an 80V mower. It belongs on this list because shoppers searching for 80V mowers often want to understand the broader Greenworks battery ecosystem, and the 24V platform powers more than 150 indoor and outdoor tools. If your project list runs longer than mowing, this kit covers a drill, impact driver, circular saw, reciprocating saw, jigsaw, multi-tool, sander, and flashlight in one box.
The 24V platform is the right scale for trim work, furniture builds, and quick repairs, but it won’t replace a true 80V mower for thick turf. Think of it as the supplement rather than the centerpiece.
Key Advantages
- Eight tools cover most DIY categories from drilling to finish sanding
- Two 2.0Ah batteries plus a 4.0Ah pack keep multiple tools running while one charges
- 65W rapid charger shortens downtime between cuts and drives
- Same battery fits hundreds of Greenworks 24V tools, useful if you already own a leaf blower or trimmer
Honest Caveats
- Not a replacement for a dedicated mower; voltage is too low for thick grass
- Carrying case organization is generic, and owners often add foam inserts to keep bits tidy
Made For
DIY homeowners building out a shared battery platform who already plan to mow with a separate dedicated mower.
Swap It Out When
Your priority is actually cutting grass; the Greenworks 80V 21in Push Lawn Mower is the better fit for that core task.
The Greenworks 60V 21in Self-Propelled Mower earns its spot because it solves the one complaint I hear most about cordless mowers: walking uphill feels like punishment. The rear-wheel self-propulsion (drive wheels that pull the mower forward at your walking pace) handles grades that would tire out a push model, and the brushless motor spins up to about 3200 RPM for clean cuts through thicker grass.
Where this differs from the 80V push mower above is straightforward: you trade voltage headroom for drive assistance. Two included 4.0Ah batteries let you swap mid-mow without waiting for a charge, and noise output runs lower than a comparable gas unit, which your neighbors will quietly appreciate.
Practical Advantages
- Self-propelled rear drive takes strain off your arms on sloped lawns
- Two batteries extend effective runtime for larger properties
- Brushless motor reaches roughly 3200 RPM for cleaner cuts in dense turf
- Quieter than gas mowers at similar cutting power, helpful for early-morning sessions
Worth Noting
- Heavier than push mowers, which complicates storage if you carry it up basement stairs
- Not an 80V unit, so cordless purists chasing maximum voltage may pass

Best Suited To
Homeowners with sloped or uneven lawns who want cordless convenience without pushing every blade uphill.
Not Your Match When
The Greenworks 40V 16in Push Lawn Mower makes more sense for tiny, flat lots where a self-propelled drive is overkill.
The Greenworks Pro 80V 21-Inch 80V Push Lawn Mower is essentially the same chassis as the first mower on this list, but with one important difference: it ships tool-only, meaning no battery or charger in the box. That single word changes who this pick is for. Existing Greenworks 80V owners who already own batteries and chargers pay less up front and skip the redundant accessories.
The 3-in-1 cutting system, mulching (returning fine clippings to feed the lawn), rear bagging (collecting clippings for disposal), and side discharge (shooting clippings out for open areas), gives you flexibility through the season. The folding handles make garage storage friendlier than fixed-handle competitors, and the brushless motor holds up well for the long haul.
What Works In Its Favor
- Lower entry cost for shoppers who already own Greenworks 80V batteries
- 3-in-1 versatility covers mulching, bagging, and side discharge
- Folding handles free up garage space
- Turbo button for tougher grass and weeds
Some Limits To Know
- Battery and charger not included, so first-time buyers should add the cost separately
- Push-only design demands leg power on hills
Whose Shelf It Belongs On
Current Greenworks 80V owners looking to expand their mower lineup without buying duplicate batteries.
A Better Fit Elsewhere
The Greenworks 80V 21in Push Lawn Mower with the 4.0Ah kit is the right call for shoppers starting from scratch who need a battery.
The Greenworks 40V 16in Push Lawn Mower sits at the compact end of the cordless lineup, and that smaller footprint is genuinely useful for tight urban lots. A 16-inch deck slips through narrow side gates and small storage sheds where a 21-inch model simply won’t fit. The trade-off shows up in cut width and runtime: smaller deck means more passes, and a 40V battery has less headroom than an 80V pack for tall or wet grass.
That said, for a small yard with short, well-maintained turf, this mower handles the job with none of the noise or maintenance of a gas engine. Owners commonly report that the lighter weight makes it a friendlier pick for older gardeners or anyone carrying it up a stoop.
A Few Strong Suits
- 16-inch deck fits narrow gates and small storage areas
- Lighter than 80V mowers, easier for older users to maneuver
- Brushless efficiency keeps runtime reasonable for small yards
- Lower price point than 80V alternatives
Possible Compromises
- More passes needed for wider lawns due to narrower deck
- 40V platform has less power reserve in tall, wet grass compared to 80V models
Perfect Match For
Urban homeowners with postage-stamp lawns who want a quiet, low-maintenance cut.
Where A Sibling Pick Shines
The Greenworks 80V 21in Push Lawn Mower handles larger or thicker yards with far less recharging.
What To Weigh Before Buying An 80V Lawn Mower
Voltage is the headline number, but it tells only part of the story. The real-world differences between 40V, 60V, and 80V platforms come down to how the motor and battery behave under load. Higher voltage gives the motor more electrical headroom, which means the blade keeps its tip speed (the rotational speed at the blade tip that determines cutting quality) when the grass gets thick. If your lawn is mostly thin fescue, a 40V mower will surprise you. If you’re pushing through St. Augustine or Bermuda, the 80V class earns its keep.
Deck size matters just as much as voltage for everyday comfort. A 21-inch deck covers ground faster but won’t squeeze through a 30-inch garden gate. Measure your gate and your storage spot before you fall in love with a wider model. Self-propelled drive helps on slopes, but adds weight and cost that flat-lot owners don’t need.
Battery strategy shapes the long-term ownership experience. A kit with two batteries and a rapid charger lets you swap mid-mow and finish large properties without waiting. Tool-only models save money up front, but only if you already own compatible batteries from the same brand. Mixing platforms across brands is a real frustration.
Brushless motors are the unsung upgrade. They run cooler, quieter, and last longer than brushed designs because there are no carbon brushes wearing out inside. The price gap has shrunk enough that I’d steer most shoppers away from brushed motors in 2026, especially for mowers used weekly.
Key Considerations Across These Picks
Wrong Turns To Avoid
The most common mistake I see is chasing voltage without checking the deck width. An 80V mower with a 21-inch deck on a small, gated yard is overkill, and you’ll wrestle it through every pass. The honest read is that matching mower size to lawn size beats chasing the highest number on the spec sheet.
Battery compatibility gets overlooked just as often. Buying a tool-only mower without confirming your existing battery is the right voltage and generation can mean an expensive surprise. Check the exact model number on your current battery before committing.
When Paying More Pays Off
The premium tier in cordless mowers earns its higher price through brushless motors, self-propelled drive, and dual-battery kits. For owners with bigger lots, sloped terrain, or thicker turf, those upgrades translate directly into faster, less tiring mow days. Flat-lot owners with small yards will feel less payoff from the premium, and a mid-tier 80V push mower covers them well.
Frequently Asked Questions
How long does an 80V mower battery actually last?
Most 80V mowers deliver roughly 45 to 60 minutes of runtime on a fully charged 4.0Ah battery under typical mowing conditions, with shorter runtimes in thick or wet grass.
Can an 80V mower handle thick or wet grass?
An 80V brushless mower generally cuts through thick grass better than lower-voltage models, but wet grass still drags runtime down and can clog the deck like any mower.
Is 80V enough to replace a gas mower?
For lawns up to about half an acre, an 80V cordless mower can fully replace a gas unit with quieter operation and no fuel mixing. Larger properties may benefit from a second battery or a wider gas mower.
How do I store an 80V mower in winter?
Store the mower in a dry, climate-moderate space and remove the battery to a room-temperature area. Avoid leaving batteries in unheated sheds where extreme cold can shorten cell life.
Are 80V mower batteries interchangeable with other tools?
Batteries are typically interchangeable within the same brand and voltage platform, but they do not cross between brands or between different voltage families on the same brand.
Closing Thoughts
Cordless mowing has quietly become the default for suburban lots, and the 80V class is where most homeowners land. Match the deck and drive to your yard, decide whether you need a battery kit or already own compatible packs, and pick the platform that fits the rest of your tool collection. The right mower disappears into your Saturday routine, and that’s the whole point.
