A weekend spent wrestling with a balky mower or dragging a cord through flower beds is a weekend wasted. The right walk-behind turns lawn care into a quick, quiet loop you actually finish before lunch. This guide sorts six cordless and manual cutting lawn mowers by deck size, runtime, and yard fit, so you can match the tool to the turf instead of the other way around.
The Essentials At A Glance
Casince 17-Inch Cordless Walk-Behind Lawn Mower
Einhell GC-EM 1742 Rotary Manual Lawn Mower
Worx WG733.1 20V 14-Inch Cordless Lawn Mower
Worx WG735 40V 14-Inch Cordless Lawn Mower
Worx WG745 40V 17-Inch Cordless Lawn Mower
EGO POWER+ LM2135SP 21-Inch Self-Propelled Mower
Taking A Closer Look At The Options
The Casince 17-inch cordless mower lands at the top because it threads a useful needle: a 17-inch cutting deck without the bulk of a 21-inch self-propelled rig. Six height settings from roughly 1 to 3 inches let you shift from a tight summer cut to a taller, drought-friendly blade length without swapping tools.
Two 20V batteries slot into the unit and stretch runtime to about 40 minutes under mild conditions, enough to cover around 5,380 square feet before a recharge. For a homeowner with a modest front and back lawn, that should mean finishing the job in one session, depending on grass thickness and how aggressively you push the deck low.
The Helpful Details
- 17-inch deck covers ground faster than 14-inch compacts, so fewer passes for the same lawn.
- Dual 20V 4.0Ah batteries extend runtime and let one pack charge while the other cools down.
- Six height positions (about 1 to 3 inches) handle seasonal shifts without buying a second mower.
- Push design keeps weight and cost down versus self-propelled models for most flat yards.
Things To Consider
- No self-propulsion, so steep slopes feel like a workout.
- Runtime can dip sharply in tall, wet grass; expect shorter sessions in spring growth spurts.
- Owners should clear clippings from the underside after each cut to keep air flow and cut quality consistent.
Who It Suits Best
Suburban homeowners with flat, compact lawns up to about a quarter acre who want cordless convenience without the premium price of a self-propelled model.
A Better Fit Elsewhere
Households sitting on sloped ground or routinely mowing damp spring grass will get more help from the EGO POWER+ LM2135SP, which adds self-propulsion and a heavier battery platform.
The Einhell GC-EM 1742 skips motors entirely. It is a hand-pushed rotary reel-style mower with a roughly 42 cm (about 16.5 inch) cutting width, and that single decision shapes who it serves.
If your lawn is small, flat, and you mow often enough that grass never gets tall, the light push feel is genuinely pleasant, more akin to sweeping than to yard work. Anyone with a postage-stamp backyard, a courtyard garden, or a side strip beside a driveway will appreciate the silence and the near-zero maintenance. Owners commonly find the manual approach ideal in tight spaces where a cordless mower’s wider deck feels clumsy.
Notable Upsides
- No battery, no fuel, no motor means no recurring charging routine or fuel mixing.
- Quiet enough to run before sunrise without waking neighbors.
- Light frame is easy to store vertically in a shed corner.
- Lower upfront cost than any powered option on this list.
Worth Noting
- Tall or damp grass clogs the cutting cylinder quickly, so weekly mowing matters.
- Pushing it across a large lawn is genuinely tiring.
- The reel works best on short, even turf; uneven ground reduces cut quality.
Made For
Tiny, tidy lawns under about 500 square feet where quiet, low-maintenance mowing beats raw power.
Skip It When
A homeowner with a quarter-acre yard and uneven terrain should reach for the Worx WG745 instead, which trades the manual simplicity for a wider 17-inch cordless deck.
The Worx WG733.1 is the smallest, lightest cordless mower in the brand’s lineup, and that positioning is the whole pitch. A 14-inch deck and a single 20V 5.0Ah PowerShare Pro battery cover up to roughly 3,200 square feet per charge under ideal conditions, which lands it squarely in balcony-adjacent territory.
The brushless motor (a motor that uses electronic controls rather than carbon brushes, reducing wear and extending runtime) gives it a longer service life than older brushed designs while keeping the deck slim enough to slip between raised beds. For gardeners with narrow side yards, stepping-stone paths, or a courtyard broken up by planters, that footprint matters more than raw cutting width.
Noteworthy Benefits
- 14-inch deck threads between flower beds and pavers without constant repositioning.
- Brushless motor extends tool life and squeezes more runtime out of each charge.
- Shares its 20V battery with the broader Worx PowerShare ecosystem, handy if you already own other tools from the line.
- Light push feel makes it approachable for first-time mower owners.
Trade Offs
- A 14-inch deck means more passes on anything over a small yard.
- Single-battery design stops mowing when the cell drains, so timing recharges matters.
- Cutting performance drops noticeably in dense, wet grass, where a 40V sibling handles the load with more authority.
Key Specs
Best Suited To
First-time homeowners with small, ornament-heavy gardens where maneuverability matters more than deck width.
Look Elsewhere When
Anyone mowing more than a modest suburban yard should consider the Worx WG735, which keeps the compact 14-inch deck but adds 40V power for tougher grass.
Where the WG733.1 is the friendly little sibling, the Worx WG735 is the same compact body tuned for thicker turf. A 40V platform and IntelliCut technology (an automatic load sensor that ramps up torque when the blade hits dense grass) make this 14-inch mower far more capable than its size suggests.
On a yard up to about an eighth of an acre, the included 20V 4.0Ah battery covers the area in a single charge, and the optimized deck with internal airflow lifts grass blades upright before the cut. The result, in our view, is a cleaner finish than most 14-inch mowers manage, particularly in spring growth. For gardeners who want a compact deck but refuse to compromise on cut quality, this lands in the sweet spot.
Strengths Worth Knowing
- IntelliCut auto-adjusts torque so the blade keeps speed in dense patches.
- 40V system handles damp or thick grass without bogging down the way 20V models can.
- 2-in-1 cutting offers both mulching and bagging from a single deck.
- Retains the slim 14-inch footprint that works well in landscaped yards.
Points To Note
- Higher price than the 20V WG733.1 for a similar deck size.
- Single-battery design still limits marathon sessions.
- The motor’s extra power adds weight that some users notice on slopes.
Who Should Grab It
Gardeners with smaller, well-planted yards where grass grows thick and uneven, and who want compact storage without sacrificing cut quality.
Consider Something Else When
Homeowners with larger, open lawns get more time savings from the Worx WG745, which pairs a wider 17-inch deck with a dual-battery setup.
The Worx WG745 is the cordless mower most people with a quarter-acre yard actually need. A 17-inch deck pairs with two included 20V 4.0Ah PowerShare batteries and a dual charger, so you can rotate packs without long downtime.
The brushless motor delivers gas-like cutting without the pull cord, the fuel mix, or the annual service. For suburban households already invested in the Worx PowerShare platform, that battery compatibility (spanning 140-plus tools across the brand’s lineup) is a quiet but meaningful perk. You will find the WG745 most useful as a routine weekly workhorse rather than a specialty tool.
Good Reasons To Consider
- 17-inch deck and dual batteries cut roughly a quarter acre per session.
- Battery swaps across 140-plus Worx PowerShare tools reduce clutter in the garage.
- Dual charger tops off both packs faster than single-port units.
- Push design keeps cost and weight down versus self-propelled alternatives.
Points To Keep In Mind
- No self-propulsion, so hilly lawns demand more effort.
- Heavier than 14-inch siblings; storing it vertically may require a sturdier shed shelf.
- Clipping bag fills quickly in tall spring grass, so emptying mid-session is normal.

Right Fit For
Households with flat quarter-acre lawns who already own (or plan to buy) Worx PowerShare tools and want a quiet, push-style daily mower.
Reach For A Different Pick When
Anyone facing noticeable slopes or larger yards should look at the EGO POWER+ LM2135SP, which trades some deck width for self-propelled drive and a far more substantial battery platform.
The EGO POWER+ LM2135SP is the heavyweight of this roundup, and it earns that slot with self-propelled drive, a 21-inch deck, and the brand’s Select Cut multi-blade system (a setup with interchangeable lower blades for mulching, bagging, or extended runtime).
This bundle includes a 56V 7.5Ah battery, a rapid charger, and an extra 5.0Ah battery that ships separately. You get enough juice to tackle lawns well beyond a quarter acre, plus a torque output EGO compares favorably to gas mowers. For larger properties, sloped ground, or anyone who has fought a heavy mower uphill, the self-propelled drive and wide deck change the daily calculus.
Where It Helps
- Self-propelled drive reduces fatigue on slopes and uneven ground.
- 21-inch deck covers ground quickly, shortening session time on larger yards.
- Select Cut system swaps between mulching, high-lift bagging, and extended-runtime blades.
- Two included batteries (7.5Ah and 5.0Ah) extend working time beyond a single charge.
Honest Caveats
- Heavier and bulkier than any push mower on this list, which complicates shed storage.
- Premium price compared to compact cordless and manual alternatives.
- Extra battery ships separately, so set-up takes an extra step before the first mow.
Whose Lawn It Belongs On
Homeowners with larger yards, slopes, or anyone who wants gas-like performance without the noise, exhaust, or pull-cord routine.
A Better Fit Elsewhere
Gardeners with small, flat lawns will overspend on the LM2135SP, and the Casince 17-inch cordless mower handles their needs at a far lower price.
What To Weigh Before Choosing A Walk-Behind Mower
Deck Width And Yard Size
The cutting deck is the metal housing that holds the blade, and its width determines how much grass you cut per pass. A 14-inch deck suits compact yards under roughly 1,500 square feet, while a 17 to 21-inch deck earns its keep on anything larger. Picking too narrow turns a 30-minute job into an hour, while oversizing a small yard makes storage harder than it needs to be.
Battery Voltage And Runtime
Voltage (the electrical pressure pushing current through the motor) sets the upper limit of cutting power. A 20V platform handles routine suburban grass, a 40V system tackles thicker growth, and 56V setups approach gas-equivalent torque. Match the platform to your grass type rather than your lawn size alone; thick St. Augustine or fescue strains a 20V motor in ways a 40V one shrugs off.
Push Vs. Self-Propelled
Push mowers cost less and store more compactly, which matters for sheds with limited floor space. Self-propelled mowers add a drive system that pulls the unit forward, reducing effort on slopes and rough ground at the expense of weight and price. Most flat suburban lots do fine with a push design, but any meaningful grade tips the balance toward self-propulsion.
Power Source: Manual, Cordless, Or Gas
Manual reel mowers reward small, even lawns with near-silence and zero maintenance. Cordless mowers balance convenience, runtime, and power for most households. Gas mowers still lead on raw runtime and torque but introduce fuel mixing, oil changes, and noise that cordless designs have largely erased for suburban use.
Picking The Right Cut For Your Yard
Where Shoppers Go Wrong
The most common misstep is buying by deck size alone. A wide 21-inch deck sounds efficient, but on a postage-stamp yard with tight corners, it produces more frustration than time saved. Equally, shoppers with a half-acre property sometimes choose a compact 14-inch mower to save money and end up doubling their mowing time. Match the deck to the open space you actually mow, not the lot size on paper.
Another trap is underestimating runtime. Battery specs sound generous in marketing copy, but real conditions (tall grass, damp lawns, mulching mode) drain packs faster. Owning a second battery, or choosing a model that bundles one, removes the wait-and-pray feeling from your weekend routine.
Where The Extra Money Goes
Spending more usually buys three things: a stronger motor platform, a wider deck, and self-propelled drive. Each upgrade pays off in different scenarios. A homeowner with flat ground and modest acreage may not notice the difference between a 20V and a 40V motor, but a sloped lot with thick grass will feel every volt of headroom.
Higher-tier mowers also tend to bundle better batteries and faster chargers, which compounds over years of use. The upgrade is worth it when you actually use the mower weekly rather than every few weekends, and when storage and transport can handle the extra weight. For occasional cutting on flat ground, the lower tier earns its keep without the premium.
Frequently Asked Questions
How Often Should You Mow With A Cordless Mower?
Weekly mowing during peak growing season keeps grass short enough that cordless mowers work efficiently. Letting grass get too tall strains the battery and produces a rougher cut, especially with mulching decks.
Can Cordless Mowers Handle Wet Grass?
Most manufacturers advise against mowing wet grass because clippings clump under the deck and the cut looks uneven. Light morning dew is usually fine, but a soaked lawn stresses both the motor and the battery.
What Is Brushless Motor Technology?
A brushless motor uses electronic controllers rather than carbon brushes to drive the rotor, which reduces friction and wear. The result is longer motor life, quieter operation, and better battery efficiency compared to older brushed designs.
Do Manual Reel Mowers Work On Uneven Lawns?
Reel mowers perform best on flat, even turf. Uneven ground lets the cylinder skip over taller blades, leaving an inconsistent finish that powered rotary mowers handle more reliably.
Is Self-Propulsion Worth The Extra Cost?
Self-propelled drive earns its price on slopes, larger lawns, or for anyone who prefers less physical effort. On small, flat yards the added weight and cost often outweigh the benefit.
Closing Remarks
Choosing among cutting lawn mowers really comes down to your lawn’s size, slope, and grass type rather than raw specifications on a page. A compact 14-inch cordless model fits tight gardens, a 17-inch deck covers most suburban lots, and a self-propelled 21-inch rig handles larger or hillier ground with less effort. Match the tool to the turf you actually mow, and the work stops feeling like work.
