Battery mowers have quietly grown up. The current crop of self-propelled cordless models handles thick spring growth, climbs modest slopes, and finishes a typical suburban lot on a single charge, all without gas, oil changes, or pull cords. For homeowners weighing a switch from gas or shopping for a first mower, the category offers real choices in deck size, battery voltage, and drive style.
The seven picks below cover tight urban lots, half-acre yards, and everything between. Each one brings a different balance of runtime, weight, and cutting width, and each one suits a particular type of yard and owner.
The Shortlist At A Glance
Casince 17 in Walk Behind Lawn Mower
EGO POWER+ 21″ Cordless Lawn Mower LM2114
Worx WG733.1 20V 14″ Cordless Mower
Worx WG735 40V 14″ Cordless Mower
Worx WG745 40V 17″ Cordless Mower
EGO POWER+ LM2135SP Self-Propelled Mower
Greenworks 80V 21″ Push Lawn Mower
Why These Options Stand Out
Casince’s 17-inch walk-behind targets first-time battery owners and small-yard households who don’t need self-propulsion. The 17-inch deck is a practical middle ground: wide enough to trim mowing time, narrow enough to slip through a standard garden gate. Compared to the larger EGO models later in this list, it skips the higher-voltage battery platform and keeps the price point approachable.
Six cutting heights between 1 and 3 inches cover everything from a tight, manicured look to a relaxed summer cut. The dual 20V battery setup also helps the mower push through a typical cool-season grass without bogging down mid-lawn.
What Makes Sense
- Dual 20V 4.0Ah batteries deliver extended runtime for small to mid-size lawns.
- Six height settings cover most common grass types and seasonal preferences.
- 17-inch deck balances mowing speed with maneuverability around beds and fences.
- Push design keeps weight and storage footprint low for shed or garage use.
Things To Consider
- Push-only operation means more effort on slopes or thick, tall grass.
- Owners commonly report the deck requires cleaning underneath after damp mowing to prevent clumping.

Consider Something Else When
Anyone mowing a sloped or half-acre yard should look at the EGO POWER+ LM2135SP for its self-propelled drive.
EGO’s LM2114 steps up to a 21-inch deck and a 56V battery platform aimed squarely at suburban lawns up to a half acre. The cutting torque is the headline: EGO claims up to 6.0 ft-lbs of torque, a figure designed to rival gas mowers in heavy spring growth. For homeowners tired of gas maintenance, this is the spec sheet that makes the switch feel realistic.
Seven cutting height positions offer more precision than the Casince’s six. The included 56V 6.0Ah battery delivers a generous runtime window for typical mid-size yards, and the 21-inch deck reduces the number of passes needed to finish the job.
A Few Highlights
- 21-inch cutting deck finishes larger lawns in fewer passes.
- Seven height positions offer fine-tuned seasonal adjustment.
- 56V 6.0Ah battery delivers extended runtime for typical half-acre lots.
- Brushless motor technology tends to extend motor life compared to brushed designs.
Points To Note
- This is a push mower; the self-propelled EGO comes later in the list for anyone needing drive assistance.
- Battery storage matters in cold climates: capacity drops noticeably in freezing temperatures, a commonly reported behavior in cordless tools.

Look Elsewhere When
Shoppers dealing with slopes or larger yards will find the EGO POWER+ LM2135SP a better fit for its self-propelled drive.
The Worx WG733.1 is built for tight spaces. At 14 inches wide and powered by a single 20V 5.0Ah PowerShare battery, it’s the most compact mower in the Worx lineup and one of the lightest cordless options available. Apartment patios, narrow side yards, and small city lots are where this mower earns its place. Compared to the broader-deck Casince earlier, the trade is width for portability.
The PowerShare battery platform is a quiet advantage: the same battery fits more than 140 Worx tools, outdoor products, and lifestyle devices. For homeowners already in that ecosystem, charging infrastructure is already on hand.
Strengths Worth Knowing
- Lightweight 14-inch deck navigates narrow gates and tight storage spaces.
- Brushless motor improves efficiency and runtime per charge.
- PowerShare battery swaps across a broad Worx tool ecosystem.
- Covers up to 3,200 sq. ft. on a single charge in typical conditions.
Points To Keep In Mind
- 14-inch deck doubles the pass count versus the EGO LM2114 on larger lawns.
- Single battery means no hot-swap option for longer mowing sessions.
Feature Card
Perfect Match For
City dwellers and small-yard owners who already use Worx cordless tools and value a compact, easy-to-store mower.
Not Your Match When
Anyone mowing a quarter-acre or larger suburban lot should consider the Worx WG745 for its wider 17-inch deck.
The Worx WG735 keeps the compact 14-inch footprint of the WG733.1 but jumps to a 40V platform. The real story is IntelliCut technology, which automatically adds torque when grass thickens, then scales back in easier conditions. For homeowners dealing with mixed turf or unpredictable spring growth, that adaptive behavior translates into a smoother cut without manual speed juggling.
The optimized deck and Airflow design work together to lift grass upright before the blade passes, which tends to deliver a cleaner finish than a basic deck in the same width class. It’s a small upgrade that adds up over a full season.
Why It Works Well
- IntelliCut torque management adapts to grass density automatically.
- Brushless motor improves efficiency compared to brushed designs.
- Airflow-optimized deck produces a cleaner cut in variable grass conditions.
- Covers up to 1/8 acre on a single charge.
Some Limits To Know
- 14-inch deck still requires more passes than 17- or 21-inch models on larger lots.
- Storage space is generous for a small mower, but the IntelliCut system adds slight cost versus basic 20V alternatives.
Technical Sheet
Built With In Mind
Homeowners with up to 1/8 acre of mixed grass types who want adaptive torque without stepping up to a wider deck.
A Better Fit Elsewhere
Anyone with a flatter, larger lot will find the Worx WG745 covers more ground per pass.
The Worx WG745 stretches the WG735’s 40V platform into a 17-inch deck sized for quarter-acre lawns. Two included 20V 4.0Ah PowerShare batteries feed a brushless motor, and the included dual charger keeps both packs topped up between sessions. For households already invested in the Worx ecosystem, the cross-platform battery use is a meaningful long-term convenience.
The wider deck strikes a balance between the Casince 17-inch and the 21-inch EGO models. It’s a sensible middle weight that handles a typical suburban front-and-back without tipping into commercial-territory weight.
Where It Helps
- 17-inch deck reduces mowing time on quarter-acre lawns.
- Dual 20V batteries extend runtime for full-yard sessions.
- PowerShare batteries work across 140+ Worx tools and outdoor products.
- Brushless motor adds efficiency and longevity over brushed designs.
Trade-Offs
- Heavier than 14-inch models; storage space should be planned accordingly.
- No self-propelled drive, so sloped lawns demand more pushing effort.
Made For
Homeowners with quarter-acre yards who want a wider Worx deck without stepping up to a 21-inch model.
Skip It When
Anyone needing self-propulsion for slopes should look at the EGO POWER+ LM2135SP instead.
EGO’s LM2135SP is the only self-propelled option on this list, and it earns that distinction with intent. The 21-inch deck pairs with up to 7.0 ft-lbs of torque, a figure designed to out-muscle gas mowers in tall or wet spring growth. A self-propelled drive removes the pushing effort on slopes and uneven ground, which matters for anyone who found the push-only EGO LM2114 tiring over a full yard.
The Select Cut Multi-Blade Cutting System ships with three interchangeable lower blades: mulching, high-lift bagging, and extended runtime. The mulching blade comes installed. The bundle also includes an extra 5.0Ah battery, which adds useful runtime for larger half-acre properties.
What It Does Well
- Self-propelled drive reduces fatigue on slopes and uneven terrain.
- Select Cut system offers mulching, bagging, and extended-runtime blade options.
- 21-inch deck with up to 7.0 ft-lbs of torque handles thick or wet grass.
- Includes a 56V 7.5Ah battery plus an extra 5.0Ah battery for longer sessions.
Honest Caveats
- The extra battery ships separately, so the bundle arrives in two packages.
- Self-propelled drive and dual batteries push this above lighter push-only mowers in both cost and weight.

Who Should Grab It
Homeowners with sloped or half-acre lawns who want gas-rivaling cutting power without gas maintenance.
Reach For A Different Pick When
Anyone mowing a small, flat lot will find the Worx WG735 lighter and more budget-friendly.
Greenworks’ 80V platform is the highest voltage in this roundup, and the 21-inch push mower is the brand’s flexible everyday workhorse. The 80V brushless motor delivers noticeably more torque than 40V or 56V systems, which shows up in tall fescue and thick spring growth. For homeowners who push through variable grass conditions, that extra headroom is a real-world benefit.
The 4-in-1 cutting system supports mulching, bagging, side discharge, and a fourth mode for different lawn-care routines. Compared to the EGO LM2114 earlier, Greenworks trades EGO’s larger 56V battery ecosystem for a higher peak voltage and broader discharge flexibility.
Reasons It Performs
- 80V brushless motor delivers strong torque in thick or wet grass.
- 4-in-1 cutting system supports mulching, bagging, and side discharge.
- 21-inch deck suits lawns up to half an acre.
- Rapid charger included for faster turnaround between sessions.
Practical Considerations
- Push-only drive makes slopes more demanding than the EGO LM2135SP.
- 4.0Ah battery may require a mid-session swap on larger half-acre lawns.
Right Fit For
Homeowners with mixed-grass lawns up to half an acre who want flexible cutting modes and higher voltage torque.
Another Choice May Suit
Anyone needing self-propulsion for sloped terrain will find the EGO POWER+ LM2135SP a better match.
Picking The Right Cordless Mower For Your Yard
Battery voltage and deck size do most of the heavy lifting in this category. Voltage, the electrical pressure that drives the motor, ranges from 20V for compact mowers up to 80V for heavier-duty platforms. Higher voltage generally means more torque, which translates into cleaner cuts in thick or tall grass. Deck size, the width of the cutting swath, controls how many passes a yard requires: a 14-inch deck is nimble but slow on open ground, while a 21-inch deck finishes wide lawns faster at the cost of maneuverability.
Runtime depends on battery capacity, usually expressed in amp-hours (Ah). A 4.0Ah battery delivers noticeably longer sessions than a 2.0Ah pack, and dual-battery designs effectively double the working time. For lawns under 1/8 acre, a single mid-capacity battery is usually enough. For half-acre properties, dual batteries or a hot-swap plan keeps the job moving.
Self-propelled drive matters most on slopes and uneven ground. Push mowers are lighter, simpler, and less expensive, but they require more effort on inclines. Anyone mowing flat terrain will likely find a quality push mower plenty capable; anyone with consistent slopes should prioritize self-propulsion.
Cutting modes add flexibility. Mulching chops clippings finely and returns them to the soil. Bagging collects clippings for a tidier finish. Side discharge handles taller growth without clogging. A 3-in-1 or 4-in-1 system covers all the bases without accessories.
Storage and weight round out the practical checklist. Cordless mowers are lighter than gas, but a 21-inch deck still demands shed or garage space. Folding handles help in tight storage areas, and lighter 14-inch models are easier to搬 up basement stairs.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Underestimating battery needs is the most common miss. A mower that advertises “up to 55 minutes” of runtime may deliver far less in tall, thick grass. Matching battery capacity to actual lawn size, with a margin for tougher conditions, prevents mid-mow interruptions.
Confusing push and self-propelled models is a close second. Listings often blur the difference in marketing copy. Self-propelled mowers have a drive motor that moves the mower forward; push mowers rely entirely on the operator. Anyone with slopes should verify the drive type before purchase.
Overlooking the battery ecosystem matters more than it seems. Mowers from brands with broad cordless tool lines let one battery charge multiple devices. Switching ecosystems mid-collection adds chargers and clutter.
What The Higher Tier Buys
Stepping up to premium self-propelled models delivers three concrete gains: torque for thicker grass, larger decks for fewer passes, and dual-battery runtime for bigger properties. The EGO LM2135SP and Greenworks 80V reflect that tier. For flat, small yards, premium features are nice but rarely essential. For sloped, half-acre lawns, the upgrade typically pays for itself in time and effort saved.
Bottom Line
The right battery mower depends on yard size, terrain, and how much pushing effort feels reasonable. Compact 14-inch models handle small urban lots with ease. 17- and 21-inch decks cover quarter- and half-acre properties efficiently. And self-propelled drive, found only in the EGO LM2135SP here, makes a real difference on slopes. Match the mower to the lawn, and the rest tends to take care of itself.
