The best cordless lawn mowers balance cutting power, battery life, deck size, and ease of handling without making yard work feel overbuilt. I rank the EGO POWER+ 21-Inch Self-Propelled 56V 7.5Ah mower as the best overall because it offers the strongest mix of runtime headroom, self-propelled drive, cutting width, and battery-platform appeal. The Greenworks 60V 21-Inch Self-Propelled mower with 2 batteries is the better fit for buyers who want extra battery depth, while the WORX 17-Inch Cordless Lawn Mower makes more sense for small yards where storage and low weight matter most. The main tradeoffs are clear: wider decks cut faster but weigh more, self-propelled drive saves effort but uses battery, and cheaper 40V models work best when grass stays under control. Keep reading for the full breakdown of how these 13 cordless mowers separate by yard size, power class, value, and ease of use.
Key Takeaways
- The EGO 56V mowers lead the ranking because they offer the best balance of cutting width, battery strength, storage design, and long-term tool-platform value.
- Greenworks is strongest when the voltage matches the yard: 60V and 80V models suit tougher lawns, while 40V and 48V options fit smaller spaces and tighter budgets.
- Compact 16- and 17-inch mowers are easier to store, but they ask for more passes and have less reserve for tall or damp grass.
- Self-propelled drive is worth paying for on heavier 21-inch mowers, while light push models can be the smarter choice for flat, small lawns.
- The best value is not always the cheapest kit; included batteries, charger speed, and battery-platform fit change the real cost over several seasons.

More Details on Our Top Picks
EGO POWER+ 21-Inch Self-Propelled Cordless Lawn Mower with 56V 7.5Ah Battery and Rapid Charger
I would rank the EGO POWER+ 21-Inch Self-Propelled Mower first because it combines 21-inch coverage, over 60 minutes of runtime, and a multi-blade setup that suits buyers who want cleaner cuts without moving back to gas. Compared with the SKIL PWR CORE 40, it offers more battery capacity and finer drive control, while the Greenworks 80V leans harder into raw voltage and a steel deck. The tradeoff is cost and heft: this is not the lightest or most budget-friendly option here. I see it as the best choice for medium to larger lawns where self-propelled control, longer mowing sessions, and cut quality matter more than saving storage weight or upfront money.
Pros:- Over 60 minutes of runtime suits longer mowing sessions
- Multi-blade system improves cut quality across mowing modes
- Touch Drive self-propelled controls help on slopes and longer passes
- 21-inch deck covers more ground than compact 16- and 17-inch models
Cons:- Higher price than basic cordless mowers
- May feel heavy for users who need a nimble mower
- Battery and charger bundle details can vary by listing
Best for: Homeowners with medium to larger lawns who want self-propelled control, longer runtime, and a cleaner multi-blade cut.
Not ideal for: Budget buyers or users who need a lightweight mower for quick trimming around tight landscaping.
- Battery:56V 7.5Ah ARC Lithium
- Runtime:60 minutes
- Cutting Width:21 inches
- Blade System:Multi-blade for mulching, bagging, and side discharge
- Self-Propelled Speed:0.9 to 3.1 MPH
- Cutting Height:1.5 to 4 inches
- Height Positions:7
- Charger Included:Yes
Our verdict“This is the pick I would choose for a capable cordless mower that can replace gas for many medium-size yards.”
SKIL PWR CORE 40 Brushless 40V 20-Inch Self-Propelled Mower Kit
The SKIL PWR CORE 40 earns its place by giving buyers self-propelled mowing, a 20-inch deck, and up to 55 minutes of runtime without stepping into the higher-price feel of the EGO 7.5Ah model. Compared with the WORX 17-Inch mower, SKIL is better for larger lawns and slopes because the drive system reduces pushing effort. Against the Greenworks 80V, though, it gives up some high-voltage punch and one inch of cutting width. I like this role for buyers who want a practical cordless upgrade with bagging, mulching, rear discharge, and compact folding storage. The main drawbacks are weight and runtime swings in thick grass, so it is less appealing if the yard is small or heavily overgrown.
Pros:- Self-propelled drive reduces effort on longer mowing passes
- Up to 55 minutes of runtime is strong for a 40V mower
- 20-inch deck balances coverage with storage practicality
- Foldable telescoping handle supports compact vertical storage
Cons:- Can feel heavy compared with compact 17-inch push mowers
- Runtime may drop in dense or damp grass
- Narrower deck than 21-inch EGO and Greenworks options
Best for: Homeowners who want self-propelled mowing and solid runtime without paying for the most premium EGO setup.
Not ideal for: People with very small yards or users who need the lightest mower possible for tight sheds and narrow paths.
- Battery:6.0Ah PWR CORE 40 lithium
- Motor Type:Digital brushless
- Cutting Width:20 inches
- Runtime:Up to 55 minutes
- Charging System:Auto PWR JUMP charger
- Handle:Foldable telescoping
- Height Adjustment:7 settings from 1.5 to 4 inches
- Mowing Modes:Bagging, mulching, rear discharge
- Weather Resistance:Yes
Our verdict“This is the mower I would point to for buyers who want self-propelled convenience at a more grounded price.”
Greenworks 80V 21-Inch Brushless Cordless Self-Propelled Lawn Mower with 4.0Ah Battery and Rapid Charger
The Greenworks 80V 21-Inch Self-Propelled Mower is the option I would place highest for buyers who care about high-voltage cutting force and a steel deck. Compared with the SKIL PWR CORE 40, it has a wider 21-inch deck and more voltage, which can help when grass gets thicker or the yard has uneven patches. Compared with the EGO 7.5Ah model, its listed runtime is shorter at up to 45 minutes, so it is not my first pick for longer uninterrupted mowing sessions. The durable build is also part of the compromise: this mower may feel heavy, and battery planning matters more if the lawn pushes past one charge. It fits buyers who prioritize cutting confidence over featherweight handling.
Pros:- 80V brushless motor gives it strong cutting potential
- 21-inch steel deck feels more substantial than smaller plastic-heavy models
- Self-propelled drive helps offset its larger build
- Rapid charger reduces downtime between mowing sessions
Cons:- Up to 45 minutes of runtime trails the longer-running EGO and SKIL picks
- Heavier build may be harder to handle in tight areas
- Battery management becomes more noticeable on larger properties
Best for: Homeowners with thicker grass, uneven lawns, or a preference for a steel-deck mower with strong cordless power.
Not ideal for: Users who need the longest runtime in this group or who want a lighter mower for frequent lifting and storage.
- Brand:Greenworks
- Model Number:MO80L00
- Power:80V
- Battery:4.0Ah lithium-ion
- Runtime:Up to 45 minutes
- Deck Size:21 inches
- Motor Type:Brushless
- Mowing Modes:Mulch, bag, side discharge
- Warranty:3 years
Our verdict“Choose this Greenworks if cutting strength and deck durability matter more to you than maximum runtime.”
EGO POWER+ 21-Inch Cordless Electric Lawn Mower with 56V 6.0Ah Battery and Charger
The EGO POWER+ 21-Inch Cordless Electric Mower makes sense for buyers who want wide-deck cordless performance without paying for the self-propelled Touch Drive package on the EGO 7.5Ah model. It matches the SKIL on listed runtime at up to 55 minutes and beats the WORX 17-Inch mower for coverage, collection capacity, and larger-yard pacing. The catch is buyer clarity: the weight is not specified, and without self-propelled assistance, handling may depend more on lawn slope and user strength. I would rank it below the premium EGO because the smaller battery and simpler drive setup make it less versatile, but above compact mowers for anyone who wants a 21-inch cordless deck with weather resistance and straightforward storage.
Pros:- 21-inch deck helps cover more lawn per pass
- Up to 55 minutes of runtime is competitive in this lineup
- One-hand height adjustment makes quick seasonal changes easier
- IPX4 weather resistance adds confidence around damp outdoor use
Cons:- No self-propelled drive listed, unlike the higher-ranked EGO and SKIL picks
- Weight is not specified, making maneuverability harder to judge
- Durability details for rough terrain are limited
Best for: Buyers with fairly flat medium-size yards who want a 21-inch cordless mower and do not need self-propelled drive.
Not ideal for: Anyone with hills, mobility limits, or a strong need to know mower weight before buying.
- Motor Type:Brushless
- Battery Voltage:56V
- Battery Capacity:6.0Ah
- Runtime:Up to 55 minutes
- Cutting Width:21 inches
- Cutting Height Settings:7 positions from 1.25 to 4 inches
- Grass Collection Capacity:2 bushels
- Weather Resistance:IPX4
Our verdict“This is the EGO I would choose for flat lawns where a wide cut matters more than powered drive assistance.”
WORX 17-Inch Cordless Lawn Mower, 2-in-1 Electric Push Mower with 7-Position Height Adjustment
The WORX 17-Inch Cordless Lawn Mower is the most targeted pick here: it is built for small yards up to 1/8 acre, lighter handling, and easy storage rather than maximum power. Compared with the SKIL PWR CORE 40 and Greenworks 80V, it gives up self-propelled drive, deck width, and heavy-cutting confidence, but its 35-pound weight makes it far less intimidating for quick weekly mowing. It also suits buyers who do not need side discharge, since this is a 2-in-1 bagging and mulching mower. I would not choose it for tall grass or larger properties, where the EGO and Greenworks models make better sense. For townhouse lawns, narrow gates, and smaller sheds, though, its size is the point.
Pros:- 35-pound weight is easier to maneuver than larger self-propelled models
- Compact 17-inch deck fits small lawns, gates, and sheds
- Includes two batteries and a charger
- Quiet 89 dB operation is friendlier for close neighbors
Cons:- Best limited to small yards up to 1/8 acre
- No self-propelled drive for slopes or long passes
- Plastic components may not satisfy buyers seeking a more rugged build
Best for: Townhouse owners and small-yard buyers who want a light cordless mower for quick, regular cuts.
Not ideal for: Large lawns, thick grass, or buyers who want self-propelled drive and a full 21-inch cutting path.
- Power:40V
- Cutting Width:17 inches
- Battery:2 x 20V 4.0Ah
- Weight:35 lbs.
- Cutting Height:1.5 to 4 inches
- Height Positions:7
- Bag Capacity:1.2 bushels
- Noise Level:89 dB
Our verdict“This is the mower I would pick for small, flat lawns where low weight beats extra cutting width.”
Greenworks 40V 17″ Cordless Lawn Mower with Brushless Motor, 4.0Ah Battery & Charger
I’d place the Greenworks 40V 17-inch ahead of smaller 16-inch push mowers when the yard is still modest but a little more deck width matters. Compared with the Greenworks 40V 16-Inch Cordless Lawn Mower, this model adds a steel deck and a brushless motor, so it feels better matched to buyers who want a sturdier cordless mower without jumping to a 21-inch self-propelled machine. The 35-minute runtime keeps it best for small to medium lawns, not stretched weekend sessions. Its main tradeoff is that it sits between categories: more capable than the lightest compact picks, but less convenient than the Greenworks 60V 21-inch self-propelled model for larger properties.
Pros:- 17-inch steel deck gives more coverage than many compact 16-inch cordless mowers
- Brushless 40V motor is built for quieter, lower-maintenance mowing
- 2-in-1 mulching and bagging gives useful cleanup flexibility
- Six cutting heights make it easier to adapt to changing lawn conditions
Cons:- Up to 35 minutes of runtime can feel short for larger or overgrown lawns
- No listed weight makes portability harder to judge before buying
- Push-only design requires more effort than self-propelled 21-inch models
Best for: Homeowners with small to medium yards who want a sturdier push mower without paying for self-propelled drive.
Not ideal for: Large-lot owners who need longer runtime or self-propelled help across slopes and thick grass.
- Battery Voltage:40V
- Battery Capacity:4.0Ah
- Cutting Width:17 inches
- Runtime:Up to 35 minutes
- Motor Type:Brushless
- Deck Material:Steel
- Cutting Heights:6
- Warranty:3-year tool and 3-year battery
Our verdict“This is the Greenworks pick I’d choose for a small-to-medium yard where durability matters more than self-propelled drive.”
Greenworks 60V 21″ Brushless Self-Propelled Cordless Lawn Mower with 2 Batteries
The Greenworks 60V 21-inch self-propelled mower earns its spot because it pushes past the limits of most 40V picks in this group. Compared with the Greenworks 40V 21-Inch Brushless Self-Propelled Lawn Mower, the higher-voltage system and two 4.0Ah batteries make it the stronger choice for buyers trying to cover up to 3/4 acre without moving back to gas. I also like that the 4-in-1 cutting setup adds leaf pickup, which gives it more seasonal use than basic mulch-and-bag models. The tradeoff is size and weight: this is more mower than a flat postage-stamp lawn needs, and terrain can still affect how long the batteries feel in real mowing conditions.
Pros:- 60V system and two batteries suit longer mowing sessions
- Self-propelled drive reduces effort on bigger yards
- 4-in-1 design handles mulching, bagging, side discharge, and leaf pickup
- LED headlights and IPX4 water resistance add practical flexibility
Cons:- Heavier than compact push mowers, especially with batteries installed
- Performance and runtime can drop on slopes or dense grass
- Overbuilt for small, simple lawns
Best for: Suburban homeowners with larger lawns who want self-propelled help and more battery headroom than a 40V mower can offer.
Not ideal for: Small-yard owners with tight storage, since the 21-inch deck and dual-battery setup add bulk.
- Battery Voltage:60V
- Battery Capacity:2 x 4.0Ah
- Cutting Width:21 inches
- Mowing Area:Up to 3/4 acre
- Drive:Self-propelled
- Cutting System:4-in-1
- Features:LED lights, IPX4 water resistance
- Warranty:4-year tool and 4-year battery
Our verdict“This is the pick I’d steer larger-yard buyers toward when they want cordless power with fewer runtime compromises.”
Greenworks 40V 16-Inch Cordless Lawn Mower with 4.0Ah Battery
The Greenworks 40V 16-Inch Cordless Lawn Mower is the most sensible Greenworks choice here for buyers who care more about easy handling than maximum cutting width. Compared with the Greenworks 40V 17-inch steel-deck mower, this model gives up some deck size and sturdiness, but its lighter build makes it friendlier for narrow side yards, small sheds, and users who do not want to wrestle a larger mower. The 5-position height adjustment covers normal weekly mowing, while the 2-in-1 setup keeps cleanup simple. I would not rank it above the Greenworks 60V 21-inch model for capacity, yet for lawns up to 1/3 acre, its lower weight may matter more than raw power.
Pros:- Lightweight design is easier to maneuver than steel-deck models
- 16-inch deck fits small yards and tighter storage spaces
- Compatible with other Greenworks 40V tools
- Quiet, maintenance-free operation suits neighborhood mowing
Cons:- Smaller deck means more passes than 17-inch or 21-inch mowers
- Battery performance can vary in tall or dense grass
- Included accessory package may be less complete than some rivals
Best for: Owners of small lawns who want a light Greenworks mower that is easy to push, store, and share across a 40V tool system.
Not ideal for: Buyers with thick grass, wide open lawns, or frequent bagging needs if accessories are not included.
- Battery Voltage:40V
- Battery Capacity:4.0Ah
- Deck Size:16 inches
- Cutting Area:Up to 1/3 acre
- Weight:Listed as 35% lighter than steel deck mowers
- Height Adjustment:5 positions
- Cutting System:2-in-1 mulch and rear bagging
- Warranty:3 years
Our verdict“This is the cordless mower I’d pick for small-yard Greenworks users who value low effort over speed.”
MZK 40V 16″ Electric Lawn Mower, 2-in-1 Brushless Cordless with Batteries & Charger
The MZK 40V 16-inch Electric Lawn Mower stands out for buyers who want the full cordless setup in one box rather than building around a tool platform. Compared with the Greenworks 40V 16-Inch Cordless Lawn Mower, the MZK leans harder into starter-friendly ownership with two 20V 4.0Ah batteries, a charger, and a 30L rear bag included. That makes it appealing for first-time cordless buyers with modest lawns. The downside is mowing stamina: up to 30 minutes trails the stronger Greenworks 40V 21-inch model, and the four height positions offer less fine tuning than Greenworks’ five-, six-, or seven-position designs. I’d treat it as a simple small-lawn kit, not a long-term answer for heavy grass.
Pros:- Includes two batteries and charger for a ready-to-mow setup
- Brushless motor is a strong feature at this starter-kit level
- 30L rear bag helps keep small lawns tidy
- Lightweight 16-inch format is easy to handle
Cons:- Up to 30 minutes of runtime limits longer mowing sessions
- Four height positions give less control than several Greenworks models
- Best suited to small or moderate lawns, not heavy-duty cutting
Best for: First-time cordless mower buyers with small to medium lawns who want batteries, charger, and bag included.
Not ideal for: Owners of thick, fast-growing lawns who need longer runtime, wider cutting, or more height range.
- Model Number:ET2602
- Power:40V
- Cutting Width:16 inches
- Height Adjustment:4 positions, 1.3 to 2.6 inches
- Battery:2 x 20V 4.0Ah lithium batteries
- Runtime:Up to 30 minutes
- Bag Capacity:30L
- Listed Deck Size:13 inches
Our verdict“This is the starter pick I’d choose for a simple cordless package when convenience matters more than high capacity.”
Greenworks 40V 21-Inch Brushless Cordless Self-Propelled Lawn Mower with 5.0Ah Battery and Charger
The Greenworks 40V 21-Inch Brushless Self-Propelled Lawn Mower makes sense for buyers who want the feel of a full-size mower while staying in the 40V Greenworks line. Compared with the Greenworks 40V 17-inch mower, its 21-inch steel deck covers ground faster, and rear-wheel self-propelled drive cuts down fatigue on bigger lawns. Compared with the Greenworks 60V 21-inch self-propelled mower, though, this model has less battery headroom and a shorter warranty. The 45-minute runtime is useful for medium yards, while vertical storage helps offset its size in the garage. I’d rank it as a practical middle path: more capable than compact push mowers, less powerful than the 60V large-yard pick.
Pros:- 21-inch steel deck cuts more lawn per pass than compact 16- or 17-inch mowers
- Self-propelled rear-wheel drive reduces pushing effort
- 3-in-1 mowing supports rear bagging, side discharge, and mulching
- Vertical storage helps manage the larger footprint
Cons:- 40V system has less headroom than the Greenworks 60V model
- May feel heavy for users moving it in and out of storage
- Runtime can vary when grass is tall, damp, or dense
Best for: Greenworks 40V owners with medium lawns who want a wider deck and self-propelled drive without changing battery platforms.
Not ideal for: Buyers with large or hilly yards who need the extra runtime and power of a higher-voltage mower.
- Voltage:40V
- Battery:5.0Ah included
- Cutting Width:21 inches
- Motor:Brushless
- Deck Material:Steel
- Runtime:Up to 45 minutes
- Height Adjustment:7 positions
- Design:Self-propelled, 3-in-1 rear bag, side discharge, and mulching
- Warranty:2-year tool and 2-year battery
Our verdict“This is the 40V mower I’d choose when cutting width and self-propelled drive matter, but a 60V upgrade feels excessive.”
Greenworks 48V (24V x 2) 17-Inch Cordless Push Lawn Mower with Batteries and Charger
I’d place the Greenworks 48V 17-Inch Cordless Push Mower highest for buyers who want a mower that feels easy to manage, store, and lift. Its poly 17-inch deck gives up width versus the WORX Nitro 21-Inch Cordless Lawn Mower, so larger yards will take more passes, but that smaller build pays off in tighter spaces and sheds. Compared with the 40V 17-Inch Battery-Powered Mower, this Greenworks model has a slightly longer claimed runtime at up to 45 minutes, though actual cutting time can drop in thick or damp grass. I like it most as a low-fuss mower for regular maintenance, not as a power-first choice for tall lawns or big weekend catch-up cuts.
Pros:- Light 17-inch poly deck is easier to push, lift, and store than wider 21-inch mowers
- Dual 24V batteries provide up to 45 minutes of claimed runtime
- 2-in-1 mulching and bagging gives buyers two cleanup styles
- Quiet, low-maintenance electric operation suits routine weekly mowing
Cons:- Narrower deck needs more passes than 20- and 21-inch cordless mowers
- Runtime can fall when grass is thick or wet
- Charging time is not listed, making battery planning harder
Best for: Homeowners with small to medium lawns who want a light push mower that is easy to maneuver around beds, trees, and narrow storage areas.
Not ideal for: Buyers with large, dense, or frequently overgrown lawns, since the 17-inch deck and variable runtime can make mowing slower.
- Power Source:48V system using two 24V lithium-ion batteries
- Deck Size:17 inches
- Battery Capacity:4.0Ah per battery
- Runtime:Up to 45 minutes
- Battery Count:2 batteries included
- Charger:Included
- Deck Material:Poly deck
- Height Adjustment:5 positions
- Operating Temperature:32°F to 113°F
Our verdict“I’d choose this Greenworks if ease of handling matters more than wide-deck speed.”
40V Cordless Lawn Mower, 17-Inch Battery-Powered with 2 Batteries, 6-Position Height Adjustment, 50L Grass Bag, 1200W Brushless Motor, 40-Minute Runtime for 500㎡ Yard
The 40V 17-Inch Battery-Powered Mower makes the most sense when grass collection is a priority but a full-size mower would be overkill. Its 50L grass bag is the key separator here: compared with the Greenworks 48V 17-Inch Cordless Push Mower, it leans more toward tidy pickup and fewer emptying stops, while the Greenworks has the longer claimed runtime. The 1200W brushless motor also gives it a stronger efficiency story than basic brushed models in this size class. I’d still keep expectations grounded. It needs both batteries for its best runtime, and the 17-inch deck will not cover ground like the WORX Nitro 21-Inch Cordless Lawn Mower. This is a practical pick for neat, modest lawns rather than heavy-duty mowing.
Pros:- 50L grass bag is generous for a compact cordless mower
- 1200W brushless motor favors efficient cutting and reduced upkeep
- Six cutting heights from 25mm to 75mm suit different lawn finishes
- 14kg weight keeps it manageable for most push-mower users
Cons:- Requires two batteries to reach its best claimed runtime
- 40-minute runtime may shrink in thick grass
- No corded fallback for buyers who need to extend mowing time
Best for: Suburban buyers with modest lawns who bag clippings often and want a compact mower with a large collection bag.
Not ideal for: People mowing large open lawns who want fewer passes, since the 17-inch deck is slower than 20- or 21-inch models.
- Cutting Deck Width:17 inches
- Battery:Two 20V 4.0Ah lithium-ion batteries
- Motor Power:1200W brushless motor
- Runtime:Up to 40 minutes
- Grass Bag Capacity:50L
- Height Adjustment:6 positions
- Cutting Height Range:25mm to 75mm
- Weight:14kg
Our verdict“I’d pick this model for tidy small-yard bagging when capacity matters more than deck width.”
WORX Nitro Cordless Lawn Mower, 21-Inch Electric Mower with 2 Batteries and Charger
I’d rank the WORX Nitro 21-Inch Cordless Lawn Mower as the feature-rich choice in this batch because it combines a wider cut with smarter power management. The 21-inch deck covers more lawn per pass than either 17-inch model here, while IntelliCut speed sensing helps match blade power to grass thickness instead of running flat-out the whole time. It also offers mulching, bagging, and side discharge, which makes it more flexible than the Greenworks 48V model’s 2-in-1 setup. The tradeoff is buyer uncertainty: runtime for larger lawns is still a question, weight is not specified, and the bigger deck may feel less nimble around tight landscaping. I’d choose it over the compact picks for open lawns, but not for cramped storage or delicate maneuvering.
Pros:- 21-inch cutting width reduces passes compared with 17-inch cordless mowers
- Brushless 40V motor is built for stronger efficiency and longer service life
- IntelliCut sensors adjust cutting speed for thin or thick grass
- 3-in-1 mowing covers mulching, bagging, and side discharge
Cons:- Runtime may still be limiting for larger lawns
- Weight is not specified, which makes handling harder to judge
- Wider deck can be less convenient in tight yards than compact 17-inch models
Best for: Homeowners with open small-to-medium lawns who want wider cutting, automatic power adjustment, and multiple clipping options.
Not ideal for: Buyers who need a very light mower for slopes, tight gates, or lifting into storage, since the listed data does not include weight.
- Cutting Width:21 inches
- Battery:Two 20V 5.0Ah PowerShare Pro batteries
- Motor:Brushless 40V motor
- Cutting Technology:AeroDeck
- Power Adjustment:IntelliCut automatic speed sensing
- Height Adjustment:7 positions
- Cutting Height Range:1.5 in to 4 in
- Included Accessories:Charger, collection bag, side-discharge chute, mulch plug
- Mowing Functions:Mulching, bagging, and side discharge
Our verdict“I’d choose the WORX Nitro when cutting width and mowing modes matter more than compact handling.”
How We Picked
I ranked these mowers by how well each one solves the real cordless problem: cutting cleanly without forcing the buyer to babysit batteries, fight a heavy deck, or overpay for power they will not use. Cutting width, voltage class, battery capacity, charger speed, self-propelled drive, storage design, and included accessories carried the most weight. The 21-inch self-propelled models rose because they cover the widest range of yards, while the compact 16- and 17-inch mowers stayed in the list because they can be better for townhomes, narrow gates, and smaller sheds. I also gave extra credit to mowers tied to a useful battery ecosystem, since a mower battery can lower the cost of future blowers, trimmers, and chainsaws.
The final order favors balanced capability over spec-sheet bragging. The EGO 56V self-propelled 7.5Ah kit leads because it has fewer compromises for the average buyer than the lower-capacity EGO, the Greenworks high-voltage models, or the compact budget picks. Greenworks models rank well when the voltage and battery bundle match the job, but the lineup splits clearly between powerful 60V/80V choices and lighter 40V options. WORX and MZK earn places for buyers who value maneuverability, price, and storage, though I do not rank them above the stronger 21-inch mowers for bigger lawns.
Factors to Consider When Choosing Best Cordless Lawn Mowers
Choosing between the best cordless lawn mowers gets easier when I separate yard demands from feature appeal. A mower that feels like a bargain on a small flat lawn can feel underpowered in spring growth, while a premium self-propelled model can be more machine than a compact yard needs. I would start with lawn size, grass density, slopes, storage space, and any battery tools already in the garage.
Match Voltage to Grass Load
Voltage is not a personality trait; it is a clue about how much load a mower can handle before it slows down. In this lineup, the 60V and 80V Greenworks models and the EGO 56V mowers are better matched to thicker grass, larger lawns, and buyers who do not mow on a perfect weekly schedule. The 40V and 48V options make more sense for smaller yards where the mower is cutting modest growth, not forcing its way through a damp spring backlog. A common mistake is buying a light 16-inch mower because it is cheap, then asking it to handle the same work as a 21-inch self-propelled model. Higher voltage usually brings more cost and weight, so I would not pay for it just to trim a tiny, flat lawn. The sweet spot is the lowest power class that can finish your hardest normal mow without slowing to a crawl.
Treat Runtime as a System
Runtime claims are best treated as best-case numbers, because real mowing eats battery faster in tall, damp, or dense grass. Battery amp-hours matter, but so do blade load, walking speed, self-propelled drive, and whether the mower has a second battery ready. That is why the EGO 7.5Ah kit, Greenworks 60V with 2 batteries, and larger Greenworks bundles are easier to trust for medium yards than single-battery compact kits. Fast charging helps if you mow in sections, but it is not a great substitute for enough battery to finish most cuts in one session. Buyers often underrate charger speed until the first half-mowed lawn is sitting in the sun. I would treat a spare compatible battery as a comfort feature, not just an add-on.
Decide Whether Self-Propelled Drive Pays Off
Self-propelled drive matters most when the mower is wide, heavy, or used on slopes. On 21-inch decks, it can turn a tiring push into steering, which is why the EGO, SKIL, and higher-voltage Greenworks self-propelled models rank above many simpler push mowers for average suburban lawns. The tradeoff is that the drive system adds cost, weight, and battery draw, so it is not automatically the better pick for every yard. For a small flat lawn, a lighter WORX 17-inch or Greenworks 40V 16-inch model can feel easier because there is less mower to wrestle around corners. Buyers with hills, uneven ground, or a larger bagging routine should lean toward self-propelled. Buyers with tight storage and many obstacles may prefer a lighter push mower even if it takes a few extra passes.
Pick Deck Width by Obstacles
Deck width decides how many passes you make, but it also changes how the mower behaves around beds, trees, fences, and gates. A 21-inch mower is the efficiency choice for open yards because it cuts more grass per pass and usually pairs with stronger motors. A 16- or 17-inch mower is slower on open ground, yet it can be the smarter buy for narrow side yards, raised beds, and sheds with limited floor space. The mistake I see in specs-first shopping is treating the wider deck as automatically better. Wider mowers are heavier, harder to pivot, and less pleasant if the yard is broken into small sections. I would pick the smallest deck that does the job without making mowing feel endless.
Think Beyond the Mower Box
Battery platform can matter as much as the mower if the buyer plans to add a trimmer, blower, hedge trimmer, or chainsaw. EGO, Greenworks, WORX, and SKIL all have broader cordless ecosystems, but they are not equally attractive if you already own one brand’s batteries. A mower kit with a large battery can make the next tool cheaper, while a bargain mower from a smaller platform can trap you into buying separate chargers later. This is one reason I rank strong platform picks, especially EGO 56V and the better Greenworks voltage families, above some lower-cost options. Replacement battery prices also deserve attention because a cordless mower is only as useful as its pack health after several seasons. The best long-run buy is the mower that fits the yard and the garage system, not just the lowest checkout price.
Frequently Asked Questions
Is a 40V cordless lawn mower enough for my yard?
A 40V cordless mower can be enough for a small, regularly maintained lawn, especially if the grass is dry and the yard is mostly flat. In this roundup, the Greenworks 40V 16-inch, Greenworks 40V 17-inch, and MZK 40V 16-inch models make the most sense for that type of buyer. I would step up to 56V, 60V, or 80V if the yard is larger, the grass gets thick, or mowing sometimes gets delayed. The risk with 40V is not that it cannot cut grass; it is that it has less reserve when conditions get messy. For buyers who want fewer compromises, the EGO and higher-voltage Greenworks models are safer choices.
Should I pay more for a self-propelled cordless mower?
I would pay for self-propelled drive if the yard has slopes, a larger footprint, or a 21-inch mower that will be heavy once the bag starts filling. It saves the buyer from pushing the full weight of the mower, which matters more over a full mowing session than it does in a product photo. The EGO 7.5Ah self-propelled, Greenworks 60V self-propelled, and SKIL PWR CORE 40 self-propelled kits all make sense for buyers who want easier handling. I would skip self-propelled for a tiny flat yard where a lighter push mower is cheaper and simpler. The tradeoff is battery use, since powered drive takes some energy that could otherwise go to blade runtime.
Which is better for most buyers, EGO or Greenworks?
For most buyers, I give EGO the edge because the 56V 21-inch mowers look like the most balanced choices on paper: strong battery options, wide cutting decks, and a mature yard-tool platform. Greenworks is the better path if its 60V or 80V ecosystem already matches the tools a buyer wants, or if a two-battery kit is priced well. The Greenworks lineup is broader in this article, but it also asks buyers to choose between 40V, 48V, 60V, and 80V paths. That can be useful, yet it can also create battery-platform confusion. I would pick EGO for a simple premium choice and Greenworks for buyers who know exactly which voltage family fits their yard and future tools.
Do I need a 21-inch deck, or is a 16- or 17-inch mower enough?
A 21-inch deck is worth it when the yard has enough open grass for wider passes to save time. It pairs especially well with self-propelled drive because the mower is larger and heavier. A 16- or 17-inch deck is better for buyers with narrow gates, small lawns, raised beds, or limited shed space. The compact models in this roundup, including WORX, Greenworks, MZK, and the 40V 17-inch option, trade speed for easier handling. I would not buy a 21-inch mower only because it sounds more powerful if the yard is chopped into tight sections.
How many batteries should a cordless mower kit include?
For a small lawn, one 4.0Ah battery can be enough if the mower is efficient and the grass is kept under control. For a medium yard, I prefer a kit with either a larger pack, such as 7.5Ah, or two batteries that can cover the full cut with margin. Two batteries also reduce anxiety when grass is damp, long, or being bagged instead of mulched. Charger speed matters more when the kit has one battery because a slow charger can pause the whole job. I would compare the battery bundle before comparing price, since the cheapest mower may need an extra pack later.
Conclusion
My best overall pick is the EGO POWER+ 21-Inch Self-Propelled 56V 7.5Ah mower because it gives the widest group of buyers the best balance of power, runtime, deck size, and ease. For value, I would choose the SKIL PWR CORE 40 20-Inch Self-Propelled Mower Kit if the price is right, since it brings self-propelled help without jumping into the most expensive tier. The Greenworks 60V 21-Inch Self-Propelled mower with 2 batteries is my premium-leaning Greenworks pick for buyers who want extra battery depth and a strong tool platform, while the Greenworks 80V model suits buyers who want maximum voltage headroom. Beginners and small-yard owners should start with the WORX 17-Inch Cordless Lawn Mower or Greenworks 40V 16-Inch model because they are easier to store and less intimidating to handle. For compact storage, pick WORX or MZK; for larger lawns, pick EGO or high-voltage Greenworks; for the best no-drama middle ground, I would stay with the EGO 7.5Ah self-propelled kit.
