Best Lightweight Cordless Mower for a Small Yard

The best lightweight cordless lawn mower is the MZK 20V 13-Inch, because 13 lb of published weight and a 9 x 16 x 17 in body clear gates and shelves nothing else here can. If your lawn runs wider than a couple of thousand square feet, the Casince 17-inch deck finishes the job in fewer passes. Deck width is what actually splits this field of seven. Below 14 inches you get carry-anywhere mowers; at 16 inches and up you get fewer passes and a lot more mower to store.

Best lightweight cordless lawn mower at a glance

How I screened these seven listings

I lined up the published specifications for all seven walk-behind mowers side by side and sorted them on four fields: deck width, published weight, cutting height range, and stated warranty. Everything else came second.

Here's what that exercise turned up. Only three of the seven publish a weight figure at all: 13 lb, 37.5 lb and 59.5 lb. One more, the Casince, states 14 kg inside a feature bullet rather than in the specifications, which is a manufacturer claim rather than a standardised figure. The remaining three publish dimensions but no mass.

That gap matters more than it looks, because "lightweight" is the whole reason most people land on a search for the best lightweight cordless lawn mower. Amazon's search does not filter on weight, so the results mix a 13 lb machine with a 59.5 lb one. You have to do that sorting yourself, and I did it here.

The screen I applied, in order:

1. A walk-behind cordless mower, not a robot, a reel or a corded model.
2. Published dimensions, so you can check the machine against your gate and your shelf.
3. A stated cutting height range or count of stops, since a single fixed height makes a mower useless for seasonal growth.
4. A grass management mode named in the listing, whether that's bagging, mulching or both.

All seven survived that. What separated them afterwards was deck width, which turned out to be the real dividing line in this set.

Deck width or weight: which decides it?

Most guides to the best lightweight cordless lawn mower compare voltage. Voltage is close to useless as a buying criterion here. Three of these mowers run on paired 20V packs, one on 40V, one on 60V, and the two 13-inch models with different voltage ratings publish an almost identical cutting height range of 1.3 to 2.6 inches.

Deck width is the figure that decides how long you spend outside. This set spans 13 in to 21 in, and that difference compounds over a lawn.

• 13 in decks (MZK 20V, etoolab): the narrowest here. More passes, but they go where nothing else goes.
• 14 in deck (Litheli): one inch wider, and dimensions of 13.3 x 24.8 x 15.1 in make it the most compact body in the set after the MZK 20V.
• 16 to 17 in decks (Greenworks 40V, MZK 40V, Casince): the middle ground, and Greenworks claims up to 1/3 acre from a fully charged 4.0Ah pack.
• 21 in deck (Greenworks 60V): fewest passes of any pick, at 59.5 lb and 42.1 x 68.9 x 25.6 in.

Weight then acts as the tiebreaker rather than the primary filter. It decides whether you can lift the mower over a step, hang it on a wall, or wheel it out of a shed without a fight. Between two mowers of the same deck width, take the lighter one every time. Across different deck widths, work out the lawn first.

1. MZK 20V 13-Inch Electric Lawn Mower — Best overall

At 13 lb with a 9 x 16 x 17 in body, this is the only pick here you can genuinely carry with one hand, and it still lists four cutting heights and a rear bag.

Best for: small fenced yards with gates and narrow side paths Skip it if: your lawn runs past a third of an acre

Nothing else in this comparison publishes a weight anywhere near 13 lb. The next-lightest published figure is 37.5 lb, which is nearly three times as much mower. Those 9 x 16 x 17 in dimensions matter as much as the mass: this fits a garage shelf, a car boot, and the gap behind a garden bench.

MZK says the brushless motor runs 2800 RPM on Low and 3400 RPM on High, and that two 20V 4.0Ah packs give up to 30 minutes on a charge. The listing puts four cutting heights between 1.3 and 2.6 inches, which covers a spring cut down low and a summer cut left longer. The kit is stated as the mower, two batteries, a single-port charger and an 8-gallon bag, so nothing further is needed on day one. The 30L rear bag empties from the back.

The trade-off is honest and it's the deck. A 13-inch cut means more laps than the 16-inch and 17-inch picks, and the stated 30 minutes is the shortest runtime claim of any mower here that quotes one. Buy it for access and storage, not for acreage.

Pros:

• Lowest published weight in this set at 13 lb
• Smallest published body at 9 x 16 x 17 in
• Two 20V 4.0Ah batteries and charger stated in the kit
• Four height stops from 1.3 to 2.6 in
• Sells faster than five of the other six picks here

Cons:

• Narrowest deck in the set alongside the etoolab
• 30-minute runtime claim is the shortest quoted here
• No warranty term published on the listing
• Only one seller lists it
• 30L bag is smaller than the Casince 50L

2. etoolab 13 Inch Cordless Lawn Mower — Best budget pick

The cheapest of the seven, and it still lists five height stops and a 2-in-1 mulching mode that the pricier MZK 20V does not claim.

Best for: patio strips and courtyard lawns on the tightest budget Skip it if: you need a published weight before you buy

This is the entry point to the set, and it gives up less than the position suggests. etoolab lists a 13-inch deck with five height settings rather than four, a 1200W max brushless motor, two 20V 4.0Ah packs and up to 40 minutes of continuous mowing. That runtime claim is 10 minutes longer than the MZK 20V's, on the same nominal battery specification.

The 2-in-1 mulching and bagging mode is the practical difference between the two 13-inch models. Mulching lets you skip the bag entirely on a light weekly cut, which on a small lawn is the difference between five minutes and fifteen. Published dimensions of 15 x 29 x 18 in tell you the handle is fixed in the measured position, so plan a taller storage slot than the MZK 20V needs.

What's missing is the number that matters most for this search. No weight appears in the specifications, so "ultra-lightweight" stays a manufacturer's phrase rather than a figure you can compare. If lifting the mower is the reason you're shopping, that gap is a real risk.

Pros:

• Cheapest of the seven picks here
• Five height stops, one more than the MZK 20V
• 40-minute runtime claim on dual 20V 4.0Ah packs
• 2-in-1 mulching and bagging both listed

Cons:

• No published weight anywhere in the specifications
• No warranty term stated
• 29-inch listed length needs more storage height than the winner
• Only one seller lists it

3. Casince Cordless Lawn Mower — Best warranty

The widest deck among the sub-20-inch picks at 17 in, the largest bag at 50L, and the only mower under a Greenworks badge with a warranty term on the page.

Best for: medium lawns needing a wider deck and six height stops Skip it if: you want coverage longer than 90 days

The Casince sits in an interesting spot: a 17-inch cut, but published dimensions of 27 x 17 x 17 in that are far tighter than the 16-inch Greenworks at 39 x 50.8 x 18.9 in. On paper that's a wide deck in a compact package, which is exactly what a mid-sized lawn with a narrow gate wants.

Casince claims six height settings from 1 to 3 inches, the broadest range in this comparison. That top figure of 3 inches is above every other pick that publishes a range, which helps if you leave grass long through a dry summer. The listing also claims up to 40 minutes and 5,380 sq ft per charge from two 20V 4.0Ah packs, a 3000 RPM brushless motor at 1200W max, and a 50L bag. That bag is the largest here, so you stop to empty it less often.

The weakness is the warranty that earns its label. 90 days is short, and it's short against the 3-year and 4-year Greenworks terms in this same set. The 14 kg weight figure also sits in a feature bullet rather than the specifications, so treat it as a claim.

Pros:

• 17-inch deck, widest of the compact picks
• Six height stops from 1 to 3 in, broadest range here
• 50L bag is the largest in this set
• Compact 27 x 17 x 17 in published body for its deck width

Cons:

• 90-day warranty is the shortest stated term here
• Weight given only as a 14 kg claim in a bullet
• Slowest-selling but one of the seven picks
• Only one seller lists it

4. Greenworks 40V 16in Push Lawn Mower — Best for families

A 3-year warranty on tool and battery, a 16-inch deck rated for up to 1/3 acre, and access to 75+ tools on the same 40V pack.

Best for: households already holding Greenworks 40V batteries Skip it if: you have to carry the mower up steps

This is the one buyers choose most often out of these seven, and the reasoning holds up. Greenworks publishes a 3-year limited warranty covering both the tool and the battery, states 37.5 lb, and claims the 4.0Ah pack cuts up to 1/3 acre depending on conditions. Five height positions run off a single lever, and the 2-in-1 system covers mulching and rear bagging.

The battery platform is the real argument. Greenworks says the 40V pack works with 75+ tools, so a trimmer or blower bought later shares the same charger and spares. For a household that mows, edges and clears leaves, that compounds in a way a one-off mower purchase does not. The brand also markets the deck as 35% lighter than steel-deck mowers, which is a comparison to gas machines rather than to anything in this set.

Set against these picks, though, 37.5 lb is heavy. It's nearly three times the winner's published figure, and 39 x 50.8 x 18.9 in is a big footprint for a 16-inch cut. If genuine portability is your priority, this is not the pick.

Pros:

• 3-year limited warranty on tool and battery
• Claimed coverage up to 1/3 acre per charge
• Five-position height via a single lever
• Shares a 40V platform with 75+ tools
• Two sellers list it

Cons:

• 37.5 lb published weight, heavy for a 16-inch deck
• Largest listed footprint of any sub-20-inch pick
• The most expensive pick apart from the 60V Greenworks
• No cutting height range in inches published

5. Litheli 14 Inch Cordless Lawn Mower — Best for quiet operation

The most compact published body in the set at 13.3 x 24.8 x 15.1 in, with a 5.0Ah pack that doubles as a power bank.

Best for: early risers mowing close to neighbours Skip it if: you want two batteries in the box

Litheli's numbers read like a mower designed around storage. At 13.3 x 24.8 x 15.1 in, it's the tightest published body in this comparison, and the adjustable handle means it collapses smaller than that in practice. The 14-inch deck adds an inch over the two 13-inch picks without adding much bulk.

Litheli describes the brushless motor as whisper-quiet and pitches early morning mowing without waking the neighbours. That's the manufacturer's framing, not a decibel figure, and no listing in this set publishes one. What is stated: a single-lever, five-position height adjustment from 1 to 2.5 inches, a 9-gallon bag, and up to 30 minutes from the included 5.0Ah battery. That pack is the largest single-cell capacity here, and Litheli says it doubles as a power bank, which is a genuinely useful extra on a lawn with no nearby outlet.

The catches are supply and specification gaps. It's the slowest seller of the seven, no weight is published, and the kit is a single battery rather than the dual packs three rivals include. Mid-mow, that means a charging break instead of a swap.

Pros:

• Most compact published dimensions in the set
• 5.0Ah battery, largest single pack here
• Battery doubles as a power bank
• Five height stops from 1 to 2.5 in
• Second-cheapest of the seven

Cons:

• One battery in the kit, no spare to swap
• No published weight or warranty term
• Slowest seller of these seven picks
• Quietness is a manufacturer claim with no figure attached

6. MZK 40V 16-Inch 2-in-1 Lawn Mower — Most versatile

A 16-inch cut on a 40 x 60 x 22 in frame, giving the wide-deck stability the compact picks can't offer on uneven ground.

Best for: sloped or uneven ground where a 16-inch deck steadies the cut Skip it if: storage space is measured in inches

This is MZK's step up from the winner: same brand, 40V rather than 20V, a 16-inch deck rather than 13. The wider frame is the point. On a lawn with dips, tree roots or a slope, a wider deck rides across the unevenness instead of scalping into it, and the 40 x 60 x 22 in body gives the handle real leverage.

The listing carries a 2-in-1 designation, and MZK states four cutting height settings from 1.3 to 2.6 inches, matching the 20V model's range. Beyond that, the feature bullets on this page repeat the smaller mower's copy, including references to a 13-inch deck and dual 20V packs. Treat those bullets with caution: the specifications say 16 in, and the specifications are the more reliable of the two.

That inconsistency is the main reason this sits sixth rather than higher. It's also one of the two most expensive picks in the set, it publishes no weight and no warranty term, and it's the second-slowest seller here. You're paying up for deck width and getting less published detail than the cheaper etoolab provides.

Pros:

• 16-inch deck for steadier cutting on uneven lawns
• Four height stops from 1.3 to 2.6 in
• 2-in-1 grass handling stated on the listing
• Largest published frame among the compact-voltage picks

Cons:

• Feature bullets contradict the 16-inch specification
• No published weight or warranty term
• Among the most expensive here without extra published capability
• 40 x 60 x 22 in body needs real storage space

7. Greenworks 60V 21in Push Lawn Mower — Best premium

The 21-inch deck, steel body, IPX4 rating and 4-year warranty make this the only pick here built for a quarter acre and wet grass.

Best for: quarter-acre-plus lawns with wet grass and long grass Skip it if: lightweight is the whole reason you're shopping

Everything about this mower is bigger. The 21-inch deck is four inches wider than the next-widest pick, the 4-year limited warranty on tool and battery is the longest term stated in the set, and Greenworks claims an IPX4 rating with a heavy-duty steel deck for rain and damp grass. The brand also cites 50% more torque than its 40V mowers and 3200 RPM blade speed.

The extras are the kind you notice weekly. Greenworks lists four-in-one handling with mulch, bag, side-discharge and a turbo leaf mode, dual self-sharpening blades, 10-inch rear and 8-inch front wheels, and LED headlights for early or late mowing. Like the 40V model, the 5.0Ah pack fits 75+ Greenworks 60V tools.

The honest problem is the number at the top of this article. At 59.5 lb and 42.1 x 68.9 x 25.6 in, it is the heaviest and largest mower here by a wide margin, and it's the most expensive pick in the set. Nobody carries this over a step. Buy it because your lawn demands the deck, not because you wanted something light.

Pros:

• 21-inch deck, widest in this comparison
• 4-year limited warranty on tool and battery
• IPX4 rating and steel deck for damp conditions
• Four-in-one handling including side-discharge and leaf mode
• LED headlights and oversized 10-inch rear wheels

Cons:

• 59.5 lb, the heaviest pick here by 22 lb
• The most expensive of the seven
• 42.1 x 68.9 x 25.6 in footprint rules out tight storage
• No cutting height range published in inches

What does the published weight actually tell you?

Less than you'd hope, because only three of seven listings state one. When you do get a figure, read it as a total that includes the battery unless the page says otherwise, and remember it says nothing about balance. A 13 lb mower with the mass over the rear wheels feels lighter on a turn than a 20 lb mower with it over the deck.

Where weight genuinely decides the purchase:

• You carry it up or down steps. 13 lb is a one-hand lift. 59.5 lb is a two-person job.
• It hangs on a wall hook. Check the fixing rating against the published figure before you buy.
• You lift it into a car. Dimensions matter as much as mass here, which is why 9 x 16 x 17 in beats a folding 37.5 lb machine.
• Someone with limited grip strength uses it. Push effort scales with mass and deck width together.

Where it barely matters: flat lawns with level access straight out of a shed. On that layout, deck width and runtime do all the work, and a heavier mower with wider wheels can be easier to push than a light one that catches on turf.

Which cutting height range do you need?

The published ranges in this set are narrower than most people expect, and they cluster. Both MZK models list 1.3 to 2.6 inches across four stops. The Litheli lists 1 to 2.5 inches across five. The Casince claims 1 to 3 inches across six, the widest here. Greenworks quotes a count of positions on both models but no range in inches.

A practical way to choose:

1. Cool-season grass left long for drought resistance wants a top setting near 3 inches. Only the Casince publishes that.
2. A tidy, short suburban finish works fine inside 1.3 to 2.6 inches, which the MZK models cover.
3. Seasonal switching is where a count of stops helps. Six beats four when you're stepping down through a spring growth spurt.
4. A first cut after a holiday is where a low bottom stop bites. Drop the deck too far into overgrown grass and you'll bog the motor.

The rule that matters is the one-third rule: never remove more than a third of the blade height in one pass. On tall grass that means two passes at descending heights, which is where extra stops pay for themselves regardless of deck width.

When does a heavier mower win?

The best lightweight cordless lawn mower for a courtyard is the wrong tool for a third of an acre, and the thresholds are reasonably clear.

• If your lawn is under roughly 2,000 sq ft, the 13-inch MZK 20V wins on access and storage. Extra passes cost you minutes, not an afternoon.
• If it's 2,000 to 5,000 sq ft, move to the 17-inch Casince. Its claim of 5,380 sq ft per charge lines up with that ceiling, and the 50L bag means fewer stops.
• If it's up to 1/3 acre, the Greenworks 40V is the pick, and the 3-year warranty covers the harder use that acreage implies.
• If it's beyond that, or the grass is often wet, the 21-inch Greenworks 60V with its IPX4 claim and steel deck is the only pick specified for it.
• If storage is the binding constraint regardless of lawn size, the Litheli at 13.3 x 24.8 x 15.1 in solves that problem better than anything else here.

One more flip. If you already own Greenworks batteries, the platform argument overrides deck width, because a bare-tool-compatible purchase changes what the whole kit costs you.

What these listings do not tell you

Three gaps run through this set, and they're worth knowing before you order.

Noise is unquantified. Litheli calls its motor whisper-quiet and Greenworks contrasts its 60V model with gas machines, but no listing here publishes a decibel figure. Cordless mowers are generally quieter than gas, and brushless motors quieter than brushed. That's the most you can conclude from what's on the pages.

Runtime claims are conditional. Every figure quoted, 30 or 40 minutes, assumes routine grass at a moderate cutting height. Thick, damp or overgrown turf pulls more current and shortens the run. The dual-battery kits from MZK, etoolab and Casince matter more than the minute count, because a swap beats a charge wait.

Warranty coverage is inconsistent. Only three of seven publish a term: 4 years, 3 years and 90 days. Four publish none at all. Where a term is missing, you're relying on Amazon's own returns window rather than a manufacturer commitment, which is a different and shorter protection.

The verdict

Split this set by tier and the choices get simple.

At the entry tier, the etoolab 13-inch is the cheapest way into a cordless mower here, and its five height stops plus 2-in-1 mulching are more capability than the position suggests. The Litheli sits alongside it with the tightest published body in the set and a 5.0Ah battery that doubles as a power bank.

The middle tier is where the winner lives. The MZK 20V 13-Inch is the best lightweight cordless lawn mower in this comparison because 13 lb and a 9 x 16 x 17 in body are figures nothing else publishes, and it still arrives with two batteries, a charger and an 8-gallon bag. The Casince is the alternate at this tier, trading portability for a 17-inch deck, six height stops from 1 to 3 inches and a 50L bag.

At the premium tier, you're buying deck width and warranty rather than lightness. The Greenworks 40V gives you 16 inches, a 3-year term and up to 1/3 acre. The Greenworks 60V gives you 21 inches, IPX4, LED headlights and 4 years, at 59.5 lb.

The cutoff is deck width against lawn size. Under 2,000 sq ft, take the 13 lb MZK. Over it, buy the wider deck and accept the weight.

FAQ

Is the cheapest lightweight cordless mower here worth buying?

The cheapest lightweight cordless mower in this set, the etoolab 13-inch, earns its place on specification rather than price alone. It lists five height stops against the winner's four, a 40-minute runtime claim, dual 20V 4.0Ah packs and 2-in-1 mulching. The gap is that no weight figure appears in its specifications, which is a real omission when portability is your goal.

Is a lightweight cordless lawn mower worth it over a gas mower?

A lightweight cordless lawn mower is worth it if your lawn fits the deck. No fuel, no oil changes, no pull-start, and a 13 lb machine goes places a gas mower cannot. The limits are runtime and width: the claims here top out around 40 minutes and 21 inches. For a courtyard or a small suburban plot, that's plenty. For an acre, it isn't.

What cutting height range should I look for?

The cutting height range you need depends on your grass type. Cool-season lawns kept long for drought resistance want a top stop near 3 inches, which only the Casince publishes at 1 to 3 inches. A short, tidy finish works fine inside the 1.3 to 2.6 inches both MZK models list. Count the stops too: six gives finer seasonal control than four.

MZK 20V or Greenworks 40V: which should I pick?

Pick the MZK 20V if you'll carry, lift or shelve the mower, because 13 lb against 37.5 lb is the whole argument. Pick the Greenworks 40V if your lawn approaches 1/3 acre, or if the 3-year tool and battery warranty and access to 75+ compatible 40V tools matter more than portability. Lawn size decides it, not voltage.

What mistake do first-time cordless mower buyers make?

The mistake first-time cordless mower buyers make is shopping on voltage. Voltage tells you almost nothing useful: two 13-inch mowers here quote different voltages and near-identical cutting height ranges. Deck width sets how many passes you make, published weight sets whether you can move the machine, and dual-battery kits beat a single high-capacity pack for uninterrupted mowing.

Measure two things this week before you order: the narrowest gate or doorway the mower has to clear, and the storage slot it lives in the other six days. Those two numbers eliminate most of this list on their own. If both are tight, the MZK 20V 13-Inch is the safe default, because 13 lb and a 9 x 16 x 17 in body are the only figures in this set small enough to fit almost anywhere, and the kit arrives complete with two batteries and a bag. Widen either measurement and the 17-inch Casince becomes the better use of your Saturday.
