Buying a brushless lawn mower means you want power without the gas, oil changes, and roar of an engine. The real question is which battery platform gives you enough runtime for your yard and which deck width fits through your gate without wrestling. That 80V number on the box sounds impressive, but it is the torque curve and the cutting height range that decide whether you finish the lawn in one charge or leave a stripe of uncut clover.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The crowd favorite that earns the top spot here delivers 7 cutting positions on a 21-inch steel deck and cuts up to half an acre on a single 80V charge — that is the benchmark for a great brushless lawn mower.
Our Picks at a Glance
How To Choose The Best Brushless Lawn Mower
Every cordless mower sounds good in the product video. The differences that matter show up when the grass is damp, the lawn slopes, and the battery bar starts dropping. Focus on these three things first.
Voltage and Battery Capacity
The voltage (40V, 48V, 56V, 80V) tells you the mower’s power ceiling — higher voltage generally means more torque for thick grass. The battery capacity in amp-hours (Ah) tells you how long that power lasts. A mower with a 4.0Ah battery will run a shorter time than one with a 6.0Ah battery, even at the same voltage. Pay attention to how many batteries are included and whether they are universal with other tools you already own.
Deck Width and Cutting Heights
A wider deck (20 or 21 inches) finishes the lawn in fewer passes but is heavier and harder to fit through narrow gates. A 15-inch deck is nimble for small fenced yards and trimming around flower beds, but you will be walking longer. The number of height positions — usually 4 to 7 — gives you control over how short or tall you leave the grass, which matters for different seasons and grass types.
Self-Propelled vs Push
Self-propelled mowers drive themselves forward at a speed you set, which saves real energy on sloped or large lawns. The trade-off is extra weight and a more complex drive system. If your yard is under a quarter acre and mostly flat, a push mower is lighter, simpler, and cheaper. If the land tilts or the lawn stretches past half an acre, self-propelled is almost mandatory.

In‑Depth Reviews
1. Greenworks 80V 21 in Self-Propelled Lawn Mower, 4.0 Ah Battery and Charger
Our pick — 4.5★ from 550+ verified ratings; the strongest balance of quality and price.
The 80V workhorse that leaves gas mowers in the dust.
You get a 21-inch durable steel deck and a brushless motor that runs three times quieter than a gas engine, so your weekend neighbors stay happy. The self-propelled rear-wheel drive with variable speed lets you match your walking pace on slopes, and the 4-in-1 system covers mulching, bagging, side discharge, and turbo leaf pickup. It cuts up to half an acre per charge with the included 4.0Ah battery — buyers report a city-sized lot uses about half a full charge, and one owner summed it up: “light weight, quiet, easy to assemble, and effective at mowing.”
What wins people over most is performance — over 150 owners single out how well it handles hills and thick grass. The battery life draws mixed notes; some want a second pack for bigger lawns. At 75 pounds and 67.72 inches long, this is a solid machine — the heft feels like a quality trade-off that gives you the steel deck and seven height positions.
Where it shines
- 80V brushless motor delivers serious torque for hills and thick St. Augustine grass
- Seven cutting positions from 1.5 to 4 inches for precise lawn control
- LED headlight lets you mow early morning or late evening
Where it holds back
- At 75 pounds, it is heavy to push if the battery dies
- Self-propel can lock up on tight turns — tip the rear wheels to disengage
- Mulch quality is adequate but not class-leading on damp grass
Grab it for: a half-acre lot where you want self-propelled help and the quietest 80V cut you can buy.
Think twice if: your lawn is under an eighth of an acre — you are hauling more mower than you need.
2. EGO 21″ Self Propelled Mower With Dual Toggle Kit (6.0Ah, 320W Charger)
Up to 6.0 ft-lbs of torque from a 56V platform that outcuts gas.
The 21-inch deck and high-efficiency brushless motor deliver cutting torque that exceeds gas mowers, according to the maker. The battery — a 56V 6.0Ah ARC Lithium pack — runs up to 50 minutes on a single charge, and owners say it lasts for two mows on a small yard. The Dual-Toggle handleset lets you engage self-propel with either hand, and seven cutting heights from 1.25 to 4 inches give you fine control over grass length. Bright LED headlights and an adjustable handle height add practical comfort for early or late mowing.
Quality and battery life are the top praise points — 44 owners highlight the build, and 42 mention the runtime as a standout. That 50.9-pound weight is noticeably lighter than the Greenworks 80V (75 pounds), making it easier to push manually. The main caveat is that performance gets mixed feedback; a few owners experienced early shutdowns, though the general sentiment is that it cuts like a beast for the first month and beyond.
Dual-toggle advantage: the self-propel engages from either hand, which beats having to reach for one specific lever on other mowers.
Straight talk: if your yard is larger than half an acre, you will want the second battery — the included 6.0Ah is great for one strong session, but not two.
Reach for this if: you want a premium 56V platform with self-propel that is lighter than the 80V competition and battery life that owners say covers two small-yard cuts.
Look elsewhere if: you need a push mower for a tiny patch — this has self-propel features you will not use.
3. EGO Power+ Electric Lawn Mower, Self-Propelled Cordless with Touch Drive, Includes (2) 56V 4.0Ah Batteries and Rapid Charger – LM2122SP-2
Two 4.0Ah batteries give you 65 minutes of gas-free cutting.
This is the EGO that comes with two 56V 4.0Ah ARC Lithium batteries and a rapid charger, so you can swap packs and keep mowing without a charging pause. The Touch Drive self-propel system engages by touch on the handle — a scroll dial on your fingertip adjusts the speed. The brushless motor delivers up to 6.0 ft-lbs of cutting torque, and the 20.5-inch deck handles a half-acre overgrown lot — owners mention it took 2.5 charges and 1.5 hours for a first cut, but weekly maintenance needs only one charge. Seven cutting heights from 1.25 to 4 inches, a 2-bushel grass bag, and IPX4 weather resistance round out the package.
Performance tops the praise list with 43 owners calling it powerful, and the dual-battery setup solves the battery anxiety that single-pack mowers create. The trade-off: at 70.8 pounds it is heavier than the single-battery EGO (50.9 pounds), and a few owners note the self-propel drains the battery faster on thick grass. The Touch Drive takes a minute to get used to, but once you dial your pace, it feels natural on slopes.
Pros
- Two batteries for hot-swapping; no downtime waiting for a charge
- 65-minute runtime beats every single-pack mower on this list
- Touch Drive self-propel is intuitive once you learn the scroll dial
Cons
- Heavier than the single-battery EGO by nearly 20 pounds
- Thick grass at low height can stall the blade — raise the deck and it powers through
- Price sits at the premium end of the list; buy for the battery ecosystem, not the mower alone
Ideal for: the half-acre yard owner who wants no-charge interruptions and a self-propel system that adapts on the fly.
Not for: budget-first buyers — you are paying for two batteries and a premium brand name, not a bare-bones machine.
4. SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower Kit, Includes 6.0Ah Battery and Auto PWR JUMP Charger – SM4910C-11
A 6.0Ah battery pack that runs 50 minutes at a price that respects your budget.
The SKIL brings a digital brushless motor and a variable-speed self-propel system to a 20-inch deck, all for a mid-range price that undercuts many 40V competitors. The included 6.0Ah battery delivers up to 50 minutes of runtime on a single charge — owners say it handles a third of an acre with juice to spare. The folding handle and telescoping design make vertical storage painless, and the 3-in-1 functionality covers bagging, mulching, and rear-discharging. Seven settings from 1.5 to 4 inches give you seasonal flexibility.
Battery life and performance are the top positive aspects here. Nearly 50 owners praise the runtime, and the same number call the performance excellent. The self-propel is adjustable and quiet — one reviewer noted it is “powerful, easy, and fun.” The main feedback is that the mower struggles with very short mossy grass on the lowest setting, so keep the deck higher for thin lawns. The weather-resistant construction adds confidence for morning dew mows.
Smart buy move: the Auto PWR JUMP charger refills the 6.0Ah battery faster than standard chargers, meaning you rarely wait long between cuts.
Pick this if: you want a large-capacity battery at a reasonable price and do not need the highest voltage (80V) platform.
skip it if: you have a steep, irregular slope — the variable-speed self-propel is nice but not as aggressive as the 80V Greenworks on hills.
5. Worx Cordless Lawn Mower, 40V 21″ 3-in-1 Grass Mower for 1/2 Acre, WG752
AeroDeck vents and IntelliCut sensors for a 1/2 acre with zero clogs.
The Worx WG752 uses a vented AeroDeck design that boosts air volume inside the cutting chamber to stop clumping and improve bag collection. The brushless motor 2.0 delivers 40% more power than first-gen brushless motors, and the IntelliCut sensors automatically increase blade speed when the grass thickens. Two 20V 5.0Ah PowerShare Pro batteries provide the 40V power — and they work with over 140 Worx tools, so your weed whacker and blower share the same packs. Seven height positions from 1.5 to 4 inches, a 3-in-1 function (mulch, bag, side discharge), and a weight of 55.6 pounds keep it manageable.
Performance gets the highest praise, with 100 owners calling it effective and the ease of use scoring highly. The dual 5.0Ah batteries deliver a runtime the maker rates up to 50 minutes, and owners with medium-small yards confirm it covers the whole lot. A few note the battery can be a bit hard to remove, and the included manual uses small diagrams that make setup less straightforward than the video instructions. Still, the general sentiment is that this is a quiet, lightweight mower with a surprisingly clean cut.
Strengths
- AeroDeck vents prevent wet grass clogs — a real time-saver in spring
- 7-position single-lever height adjust is fast and tool-free
- PowerShare batteries compatible with 140+ Worx tools
Weaknesses
- Battery removal requires a firm push-and-hold, which some find fiddly
- Instruction manual is sparse — rely on video setup guides
- Not self-propelled; best for flat to gently sloped lawns
Best for: the half-acre homeowner who wants a clean, clog-free cut with a battery platform that expands to other yard tools.
Think twice if: you need self-propelled for a steep grade — this is a push mower, and 55.6 pounds gets heavy on an incline.
6. Greenworks 48V 20 in Push Lawn Mower, (2) 4.0 Ah Batteries and Charger
Two batteries, one reliable push mower that has earned over 800 positive ratings.
This Greenworks uses two 24V PowerALL batteries — each with a USB hub — to deliver 48V power to a 20-inch alloy steel deck. The brushless motor provides the quiet torque Greenworks is known for, and the 4-in-1 system covers mulching, rear bagging, side discharge, and a turbo button for leaf pickup. The kit includes two 4.0Ah batteries and a dual-port rapid charger, with the maker claiming up to 45 minutes of runtime. Owners with a third of an acre report it handles thick grass without clogging and outperforms their old gas mower in cut quality.
Performance is the top praise — 97 owners call it effective, and 82 highlight the build quality. The 67.2-pound weight is heavier than the 48V platform suggests, but owners say it pushes easily enough on flat lawns. The big caveat is battery life: 119 owners mention it as a mixed point, with some finding 45 minutes accurate and others reporting it dies after 20 minutes in tall grass. Splitting the mowing into two sessions or buying spare batteries solves it, but it is a real limit for a single pass over a big lawn.
Owner-verified after two years: “still works reliably, zero maintenance, cuts faster than a zero-turn riding mower.”
Choose this if: you want a dependable push mower from a trusted brand and do not mind splitting a large mow into two battery changes.
Avoid if: you need self-propelled on a slope — this is a pure push machine.
7. LiTHELi Electric Lawn Mower, Self-propelled Cordless 40V(2x20V) 18.5″ Brushless Mower with Electric Cutting Height Adjustment
Push a button to change cutting height — no bending, no messing with levers.
The LiTHELi is the only mower on this list with an electric cutting height adjustment that lets you change between 6 positions with one touch, no bending required. The 18.5-inch deck runs a brushless motor that spins up to 4100 RPM — the maker calls it Easysurge Technology, and it handles thick zoysia without hesitation. The self-propelled system has variable speed from 1.3 to 2.9 MPH, and the T-shaped single rod handle folds for storage without removing the grass bag. Two 20V 4.0Ah batteries deliver up to 30 minutes of runtime, covering up to a sixth of an acre per charge.
Effectiveness and maneuverability are the top positives — 39 owners praise the cut, and 34 highlight how easy it is to steer. The electric height adjustment is the feature most owners mention first. The battery life draws mixed feedback, with 57 owners noting the 30-minute runtime is tight for larger lawns. A few find the rear-wheel drive tricky on tight turns, and the plastic grass catcher fills fast. On the positive side, it collapses small for storage and runs very quietly.
Unique Advantage
- World’s first electric cutting height adjustment on a cordless mower — push-button, no stooping
- 4100 RPM blade speed handles thick grass without bogging down
- Self-propelled variable speed from 1.3 to 2.9 MPH
Limitations
- 30-minute runtime is short — plan for multiple battery sessions on medium lawns
- Rear-wheel drive can lock on tight turns
- Grass catcher fills fast; plan extra stops
Best for: the buyer who wants the coolest feature — electric height adjust — on a lightweight, self-propelled mower for a small yard.
Pass if: runtime is your priority; the 30-minute window is noticeably shorter than the Greenworks 80V or the EGO 56V options.
8. Worx Cordless Lawn Mower, 40V 17″ 2-in-1 Grass Mower for 1/4 Acre, WG745
The 39.7-pound buddy that sneaks under shrubs and cuts a quarter acre.
The Worx WG745 is a compact 17-inch mower built for small yards up to a quarter acre. The brushless motor 2.0 is designed to handle tough weeds without hesitation — as one owner put it, “great little machine for a smaller yard.” It runs on two 20V 4.0Ah PowerShare batteries that combine for 40V power, and the IntelliCut technology automatically adjusts the blade speed based on grass density to save battery. The 2-in-1 system switches between mulching and rear bagging, and the slim Cut-to-Edge deck lets you trim right next to fences and flower beds. Six cutting heights from 1.5 to 4 inches, and it weighs just 39.7 pounds fully assembled.
Performance and battery life are the top praises here — 35 owners call it effective, and 21 highlight the runtime as sufficient for small lawns. The lightweight design means easy maneuverability, and the quiet operation means no earplugs needed. The main complaint is assembly: 13 owners found the printed instructions nearly useless, and setup took some close to two hours. The blade could be more aggressive for dense grass, and owners recommend sharpening it regularly for a clean cut.
Owner wisdom: “remember to begin charging your batteries an hour to 90 minutes before you would like to mow.”
Perfect for: the townhouse or small-lot owner who wants the lightest, quietest mower that stores upright and shares batteries with other Worx tools.
Not for: anyone with a quarter-acre-plus lawn — the 17-inch deck and 4.0Ah batteries will run out of steam before the yard is done.
9. LawnMaster Lawn Mower, Brushless Cordless Lawn Mower 48V MAX 15-inch with 2X24V MAX 4.0Ah Battery and a Dual Charger-CLMF4815E
The lightest entry at 34.3 pounds — ideal for the tiniest patches of grass.
The LawnMaster is a 15-inch, 34.3-pound mower that runs on a 48V MAX system powered by two 24V 4.0Ah batteries. The brushless motor spins at 3100 RPM, and the 4 cutting positions range from 1.4 to 2.5 inches. It is built for small yards — one owner reported three cuts on a 17×30-foot lawn with the batteries still showing green. At 34.3 pounds, it weighs barely half of what the 75-pound Greenworks does, and the folding push handles make compact storage straightforward. The dual charger handles both batteries at once, and users report a 45-minute runtime with no battery drop.
Quality and weight are the top positive aspects — 26 owners call it well-constructed, and 22 highlight how light it is. The 15-inch width and all-plastic construction make it very easy to carry and store. Performance gets mixed marks (36 owners note it), with some saying it does a great job on tall grass and others reporting overheating batteries after short use. The small grass catcher fills quickly, and this mower is only suitable for very small lawns — the majority of owners agree on that.
Honest trade-off: the lightest mower on the list is also the narrowest (15 inches) and the least powerful at 3100 RPM — fine for a trim patch, frustrating for anything larger.
Choose for: a tiny city yard, a patio, or a lawn that measures in feet per side, not acres.
Pass if: you have even a quarter acre to cover — the 15-inch deck and mixed battery performance will leave you stopping to recharge.
Understanding the Specs
Voltage and Amp-hours (V and Ah)
Voltage tells you the motor’s power potential — higher voltage (80V vs 40V) typically means more torque for cutting thick, tall grass. Amp-hours (Ah) tells you how long the battery lasts at that power. A 6.0Ah battery runs longer than a 4.0Ah battery at the same voltage. The real-life equation is simple: higher V plus higher Ah equals more mowing time with more force. Most cordless mowers use 40V or 56V platforms, while the 80V class is reserved for heavy-duty models that cut through dense grass or larger yards.
Deck Material and Width
Deck material affects weight and corrosion resistance. Steel decks (like the 21-inch deck on the Greenworks 80V) are durable and give a clean cut but add pounds. Alloy steel is lighter than standard steel but still tough. Polypropylene decks (used on the Worx models) are lighter and never rust, but they flex more and may not feel as solid on uneven ground. Deck width determines how many passes you need: a 21-inch deck finishes faster than a 15-inch deck on the same lawn, but the narrower deck is easier to fit through gates and store.
