Gas mowers still dominate suburban driveways, but the cordless category has quietly closed the gap. Modern 56V and 80V battery platforms now deliver enough torque and runtime to handle most residential lawns, sidestepping oil changes, fuel stabilizer, and the pull-cord ritual. I put together this list for anyone who wants gas-class cutting performance without owning a small engine.
A Fast Comparison Of The Options
Greenworks 80V 21in Push Lawn Mower (4.0 Ah Battery)
EGO POWER+ 21″ Cordless Self-Propelled Mower (LM2114SP)

EGO Power+ 21″ Self-Propelled Mower (LM2123SP-2)
Taking A Closer Look At The Options
The Greenworks 80V push mower is the kind of pick that quietly covers the basics for a half-acre lot without demanding attention. The 21-inch steel deck trims mowing time on wide runs, and the brushless motor, which uses electronic control instead of carbon brushes to reduce wear, keeps noise and vibration modest. For homeowners stepping away from gas, this is a low-friction entry point.
The 4.0Ah battery ships in the box along with a rapid charger that refills in roughly an hour. A single lever adjusts deck height across the range, so changing cut length takes one motion instead of four. Owners running weekly cuts on cool-season grass generally find the runtime lands where Greenworks claims it.
Useful Touches
- 21-inch steel deck trims wide passes faster than 16 or 17-inch alternatives
- Brushless motor design extends tool life and quiets operation
- Rapid charger refills the 4.0Ah pack in roughly 60 minutes
- Single-lever height adjustment speeds up seasonal cut changes
Things To Consider
- Push-only design tires out long, sloped cuts without self-propel assist
- Run-time figure assumes light, dry grass; thick spring growth drains the pack faster
Quick Facts
Right Fit For
Homeowners with a flat, quarter-to-half-acre lawn who want a battery platform with room to grow.
Look Elsewhere When
The yard has steep grades, since the EGO POWER+ 21″ Cordless Self-Propelled Mower (LM2114SP) handles hills with much less fatigue.
EGO built the LM2114SP for shoppers who want gas-class torque without gas-class maintenance. The 56V platform produces 6.0 ft-lbs of cutting torque (rotational energy the blade uses to shear grass), enough to push through tall fescue without bogging. Dual self-propel levers mean left- or right-handed users both stay in control.
The speed dial sits under one thumb, which keeps you from breaking stride to fiddle with a separate control. The brushless motor stretches runtime and stays cool during long cuts. Compared to the Greenworks push mower above, this is the next step up once slopes enter the picture.
Real-World Strengths
- 6.0 ft-lbs of cutting torque handles thick, tall grass without stalling
- Self-propel with both left and right triggers for ambidextrous use
- Brushless motor extends service life and quiets operation
- On-the-fly speed dial adjusts pace without stopping
Worth Noting
- Self-propel system adds weight, which may tire out smaller users on long cuts
- 56V battery costs more to replace than lower-voltage packs
- Steel deck holds up, but adds storage bulk compared with composite decks
Built With In Mind
Homeowners on sloped lots up to three-quarters of an acre who want cordless convenience plus gas-class cutting strength.
Skip It When
You mostly mow a small, flat patch, since the Casince 17″ Cordless Walk-Behind Lawn Mower keeps things lighter and simpler.
The Casince 17-inch fits the kind of lawn that doesn’t deserve a 21-inch deck. Two 20V 4.0Ah batteries run in tandem to deliver up to 40 minutes of cutting, which translates into roughly 5,380 square feet per charge under normal conditions. Six height positions span 1 to 3 inches, enough range for both cool-season turf and warm-season grasses.
The narrower deck pivots tightly around trees and raised beds, which matters more than raw width on a postage-stamp yard. Folding handles help with apartment storage, and the brushless motor design trims noise for early-morning cuts. Relative to the Greenworks 80V push mower, this trades deck width for agility.
Why It Works Well
- 17-inch deck pivots around tight landscaping without scalp marks
- Dual 20V 4.0Ah batteries extend runtime to roughly 40 minutes
- Six cutting heights from 1 to 3 inches handle varied grass types
- Folding handles shrink the footprint for shed or closet storage
Trade Offs
- Smaller deck lengthens mowing time on wider lawns
- Two batteries must both be charged, doubling dock space
Feature Snapshot
Who It Suits Best
Suburban townhouse and small-lot owners who prioritize tight turning over raw deck width.
Consider Something Else When
Your lawn runs wider than a quarter-acre, since the Greenworks 80V 21in Push Lawn Mower covers ground noticeably faster.
The LM2114 strips the self-propel system out of the LM2114SP and trims the price in the process. The same 56V brushless motor still pushes 6.0 ft-lbs of cutting torque, which keeps tall spring growth from bogging the blade. The 56V 6.0Ah battery delivers roughly 55 minutes of runtime on a flat lawn.
Seven cutting heights give finer control than the typical five-step lever on competing mowers. Owners with flat, mid-size lots benefit from the simpler push-only design, which weighs less and stores easier than the self-propelled sibling above.
Everyday Perks
- 6.0 ft-lbs of torque matches many gas mowers in tall grass
- Seven height positions offer finer seasonal tuning than typical 5-step decks
- Up to 55 minutes of runtime covers most mid-size lawns
- Push design sheds weight for easier storage in tight sheds
Honest Caveats
- No self-propel means more effort on any incline
- Single battery requires recharging mid-cut on larger lots
Perfect Match For
Flat-lot homeowners who want EGO cutting power without paying for the self-propel system they won’t use.
A Better Fit Elsewhere
Anyone with hills to mow should step up to the EGO POWER+ 21″ Cordless Self-Propelled Mower (LM2114SP) for drive-assist.
This “tool only” version of the Greenworks Pro 80V mower ships without a battery or charger, which makes sense for anyone already running the Greenworks 80V ecosystem. The 21-inch deck and brushless motor match the kit version above, while the 3-in-1 system supports mulching, bagging, and side discharge. A turbo button adds a temporary torque boost for stubborn patches.
Folding handles compress the footprint for shed corners. If you already own an 80V trimmer or blower, this lands as a logical add-on that shares the same batteries and chargers across the lineup.
What Pays Off
- Skips bundled battery cost when you already own 80V Greenworks packs
- 3-in-1 cutting handles mulching, bagging, and side discharge
- Turbo button delivers a quick torque boost for thick grass
- Folding handles simplify off-season storage
Points To Note
- No battery in the box, so it’s a non-starter without existing 80V packs
- Push design lacks self-propel for sloped lawns
- Turbo mode drains the battery noticeably faster
Made For
Owners of Greenworks 80V trimmers, blowers, or chainsaws expanding the same battery platform into a mower.
Not Your Match When
You need a battery and charger in the box, since the Greenworks 80V 21in Push Lawn Mower (4.0 Ah Battery) version ships ready to cut.
The LM2135SP pushes torque to 7.0 ft-lbs, which steps above the LM2114SP covered earlier. The Select Cut Multi-Blade system ships with three interchangeable lower blades: a mulching blade, a high-lift bagging blade, and an extended-runtime blade. That flexibility changes the mower’s character depending on the task.
EGO bundles a 7.5Ah battery plus an extra 5.0Ah pack, which roughly doubles the practical runtime on larger lots. Swapping batteries mid-cut takes seconds, and the brushless motor keeps vibration low across long sessions. This is the cordless choice for anyone who used to swear by a 200cc gas engine.
Key Advantages
- 7.0 ft-lbs of torque tackles dense, overgrown patches without slowdown
- Select Cut system swaps between mulching, bagging, and runtime blades
- Dual battery bundle extends usable runtime to roughly 90 minutes
- Self-propel drive assists on sloped or long-distance cuts
Where It May Fall Short
- Higher price than single-battery EGO kits
- Three-blade system adds storage space for spare blades
- Bundled extra battery ships separately, so arrival timing varies
Whose Shelf It Belongs On
Homeowners with half-acre-plus lawns or thick, fast-growing grass who want cordless muscle without compromise.
Reach For A Different Pick When
Your yard is small enough that one battery handles the cut, making the EGO POWER+ 21″ Cordless Self-Propelled Mower (LM2114SP) a smarter spend.
The DLM330Z runs on Makita’s 18V LXT slide battery platform, which is one of the most mature cordless systems in the trades. The 330mm cutting width (about 13 inches) suits small gardens where agility matters more than deck size. Soft start ramps the motor up gently, which protects both the gears and your wrist.
Maximum output sits at 450W with a 4,300 rpm blade speed. The 3-in-1 cutting system supports mulching, bagging, and rear discharge. Since this is a bare tool, you’ll need to bring your own 18V LXT batteries and charger to the party, which limits appeal to existing Makita owners.
Benefits That Matter
- 330mm deck pivots tightly in narrow garden paths
- 18V LXT compatibility taps into Makita’s huge cordless ecosystem
- Soft start reduces mechanical shock and improves operator comfort
- 3-in-1 cutting handles mulching, bagging, and rear discharge
Practical Considerations
- Battery and charger not included, so cost stacks up for new Makita shoppers
- Narrow deck lengthens mowing time on open lawns
Best Suited To
Tradespeople and homeowners already invested in Makita’s 18V LXT platform who want a shared-battery lawn solution.
Where Another Pick Suits Better
Shoppers without Makita batteries should consider the Casince 17″ Cordless Walk-Behind Lawn Mower, which ships ready to mow.
The LM2123SP-2 belongs to EGO’s 600 Series and introduces Touch Drive self-propel, where pressure sensors in the handle engage the drive wheels based on how hard you press. It’s a different feel from the lever-based self-propel on the LM2114SP covered earlier, and many users adapt within a single cut.
EGO ships two batteries, a 56V 6.0Ah and a 4.0Ah, which combine for up to 80 minutes of runtime. The 6.0 ft-lbs of cutting torque matches the LM2114SP, but the longer total runtime moves this into large-lot territory. Steel deck construction adds durability for frequent mowing schedules.
The Good Stuff
- Touch Drive self-propel adjusts with handle pressure for natural control
- Combined 6.0Ah + 4.0Ah batteries stretch runtime to roughly 80 minutes
- 6.0 ft-lbs of torque handles typical residential grass without strain
- 21-inch steel deck balances cut width and durability
Details To Watch
- Touch Drive takes a cut or two to learn compared to lever self-propel
- Premium pricing puts this above basic EGO kits
- Two batteries require two charging slots
Feature Card
Who Should Grab It
Tech-forward homeowners with large, varied lawns who want the longest runtime in the EGO lineup.
Swap It Out When
Your yard fits comfortably under 50 minutes of cut time, since the EGO POWER+ 21″ Cordless Lawn Mower (LM2114) costs noticeably less.
What Matters Most Before Choosing Cheap Lawn Mower Gas
Deck Width Versus Lawn Size
The 17-inch decks on picks like the Casince mower trim tighter corners but extend mowing time on wide lawns. A 21-inch deck, found on most Greenworks and EGO models here, covers about 50% more ground per pass, which matters once your lawn crosses a third of an acre. For urban lots under 2,000 square feet, a narrower deck often finishes the job faster thanks to better maneuverability.
Battery Voltage and Runtime Reality
Higher-voltage platforms, like 56V and 80V, deliver more torque but also cost more per battery. Manufacturers rate runtime under ideal conditions, meaning dry, level grass at moderate thickness. Thick spring growth, damp lawns, and tall fescue drain packs noticeably faster. For lawns over half an acre, dual-battery kits such as the LM2135SP offer insurance against mid-cut power loss.
Self-Propel Versus Push
Self-propel takes the strain out of sloped lots and long straight cuts. Touch Drive systems on the LM2123SP-2 use pressure sensors, while lever systems on the LM2114SP respond to a trigger pull. Push mowers cost less and weigh less, which helps in storage and on flat lawns. Match the drive type to your terrain rather than defaulting to the most expensive option.
3-in-1 Cutting Flexibility
Mulching, bagging, and side discharge each serve different needs. Mulching returns clippings to the lawn as natural fertilizer. Bagging suits allergy sufferers and pristine lawn looks. Side discharge handles tall, wet grass without clogging. Models like the Greenworks Pro 80V (Tool Only) and Makita DLM330Z offer all three, which keeps options open through changing seasons.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Choosing deck width before measuring your lawn leaves people with a mower that’s either too wide to pivot or too narrow to finish in reasonable time. Skipping the battery check is another common miss, since tool-only versions like the Greenworks Pro 80V (Tool Only) and Makita DLM330Z leave you stuck without a compatible pack. Finally, ignoring slope means a push mower becomes exhausting on any grade beyond a gentle rise.
Where The Extra Money Goes
Stepping up to EGO’s higher-tier models adds torque, longer runtime bundles, and self-propel refinements like Touch Drive. The LM2135SP and LM2123SP-2 both push past basic EGO kits with features that show up on thick grass and large lots. For flat, smaller lawns, the upgrade rarely justifies itself. The honest read is that the extra spend pays off when your lot actually demands it, and not before.
Frequently Asked Questions
How long do cordless lawn mower batteries actually last?
Most lithium-ion packs in this category hold usable capacity for roughly 3 to 5 years with regular use, though high-heat storage shortens that window. Charging immediately after a hot cut stresses cells more than letting the pack cool first.
Can cordless mowers handle wet grass?
Battery mowers can cut damp grass, but runtime drops noticeably and clumping increases. Wet clippings also stick to the deck, which calls for more frequent cleaning. Manufacturers generally recommend waiting for dry conditions for the cleanest cut.
What maintenance does a cordless mower need?
Blade sharpening once or twice per season, occasional under-deck cleaning to prevent corrosion, plus battery terminal care. There’s no oil to change, no spark plug, and no fuel stabilizer, which is the main reason cordless has gained ground on cheap gas mower ownership.
Are brushless motors worth the upgrade?
Brushless designs run cooler, last longer, and squeeze more runtime per charge than brushed equivalents. The cost difference shows up front, but the long-term reliability advantage is real for anyone mowing weekly through the season.
How big a lawn can a 56V or 80V mower handle?
Single-battery kits typically cover up to half an acre comfortably. Dual-battery kits like the LM2135SP extend that range, while the LM2123SP-2’s combined battery bundle pushes toward a full acre on flat ground.
The Takeaway
Cordless mowers have earned the right to sit on the same shelf as gas models for most homeowners. Match the deck width to your lawn size, choose self-propel only if slopes demand it, and pay attention to whether the kit includes the batteries you need. The right pick for a townhouse lawn looks nothing like the right pick for a half-acre lot, but both exist on this list.
