Gas fumes, pull cords, and weekend oil changes used to be part of lawn care. Battery power has quietly rewritten that routine, and a wide range of cordless walk-behind models now handle small lots and mid-size lawns without the noise. This lineup covers five solid options for homeowners who want clean cuts, lighter storage, and far less maintenance.
A Quick View Of The Lineup
Greenworks 80V 21in Push Lawn Mower
EGO POWER+ 21″ Self-Propelled Mower LM2135SP
Honda HRX-BE 21″ Battery Mower HRX217YXBEXA6
Honda HRX-BV 21″ Battery Mower HRX217YXBVKA4
Makita DLM330Z 18V LXT Lawnmower
A Deeper Look At The Lineup
The Greenworks 80V sits at the friendly end of the cordless walk-behind market, pairing a 21-inch steel cutting deck with a brushless motor (a motor with no carbon brushes, so it runs cooler and typically lasts longer) for cleaner, quieter mowing than most small gas units. It arrives with a 4.0Ah battery and a rapid charger that tops the pack off in roughly an hour, which matters when weekend schedules get tight.
For a homeowner with a modest suburban lot under a quarter acre, the single-lever height adjustment keeps setup painless, and the wide deck finishes a typical lawn in fewer passes than narrower 16-inch models. Compared to the Honda HRX-BE below, this Greenworks skips mulching versatility but wins on price-to-performance.
Key Advantages
- Brushless motor delivers quieter operation and longer motor life than brushed alternatives
- Rapid charger refills the 4.0Ah battery in about an hour, useful between mowing sessions
- 21-inch steel deck covers typical home lawns faster than compact 16 to 17-inch mowers
- Single-lever height adjustment speeds up seasonal cut-height changes
- Push design keeps weight and storage footprint smaller than self-propelled models
Worth Noting
- No self-propulsion, so long uphill stretches can feel like work on thicker turf
- Run-time varies with grass density, so dense or wet lawns may need a second battery
- Steel deck adds durability but also storage weight versus plastic alternatives
Feature Snapshot
Who It Suits Best
Homeowners with flat, mid-size lawns who want a low-maintenance, walk-behind cut without self-propelled complexity.
Consider Something Else When
The EGO POWER+ LM2135SP is a smarter match for anyone managing slopes or thicker turf where self-propelled drive reduces fatigue.
EGO’s LM2135SP steps into heavier territory with a 56V platform, a self-propelled drive, and the Select Cut multi-blade system that swaps between mulching, bagging, and extended-runtime blades. The bundle ships with both a 7.5Ah battery and an extra 5.0Ah pack, so you can rotate packs for back-to-back mow sessions without waiting on a charger.
This is the pick for homeowners with sloped or oddly shaped lawns where pushing becomes a chore. The self-propelled rear drive lightens long passes, and the wide deck finishes large yards efficiently. Against the Honda HRX-BV further down, the EGO trades some bagging refinement for genuinely stronger runtime flexibility.
A Strong Showing
- Self-propelled drive reduces fatigue on long, sloped, or uneven lawns
- Two included batteries cover larger yards or split mowing days
- Select Cut blade system adapts between mulching, bagging, and runtime priorities
- 56V platform delivers strong torque for thicker grass conditions
Trade Offs
- Extra battery ships separately, so it may arrive after the mower
- Self-propelled system adds weight, which affects tight storage spaces
- Higher platform cost than push-only models like the Greenworks above
Made For
Homeowners with mid-to-large lawns, slopes, or mixed terrain who want self-propelled drive and interchangeable battery use across the EGO ecosystem.
Look Elsewhere When
The Makita DLM330Z is a better fit for narrow urban plots or anyone already invested in 18V LXT tools and needing a compact deck.
Honda brings its gas-engineered DNA to the battery side with the HRX-BE, a 21-inch walk-behind that focuses on cut quality and bagging refinement. The 4-in-1 Versamow system with Clip Director lets you dial between mulching, bagging, side discharge, and leaf shredding without swapping attachments, a real time-saver during fall cleanup.
This mower suits homeowners who care about the finish more than the runtime numbers. Where the EGO above prioritizes power and battery capacity, the HRX-BE leans into Honda’s reputation for build feel and mulching consistency. Depending on your grass type and clipping preference, that detail-oriented engineering can be the deciding factor.
The Practical Payoff
- Versamow Clip Director switches cutting modes without extra tools or attachments
- Honda-grade engineering shows in deck rigidity and long-term durability
- 21-inch deck pairs wide coverage with refined mulching and bagging results
Points To Note
- Premium positioning puts it above push-style budget options
- Battery and runtime specifics vary by use, so dense lawns may need planning
Right Fit For
Homeowners who want Honda’s cut quality and the flexibility of a true 4-in-1 system for seasonal lawn care beyond just mowing.
Skip It When
The Honda HRX-BV is worth a look if you want variable-speed self-propelled drive for larger or hillier lawns.
The HRX-BV takes everything the HRX-BE offers and adds variable-speed self-propulsion, which adjusts drive pace to your walking speed and the terrain. The same Versamow 4-in-1 system handles mulching, bagging, discharge, and leaf shred, so it doubles as a fall cleanup tool when the leaves pile up.
This is the Honda for larger suburban lots where pushing a mower gets old fast. The variable-speed drive is the real upgrade over the BE trim level, and it makes a noticeable difference across uneven ground. Compared to the EGO LM2135SP, this Honda leans more toward refined cut quality than raw battery versatility.
Everyday Wins
- Variable-speed self-propelled drive matches pace to terrain and operator
- Versamow system handles mulching, bagging, discharge, and leaf shredding
- Honda engineering aims at long service life rather than disposable design
Honest Caveats
- Higher price than push mowers or basic self-propelled alternatives
- Heavier than compact options like the Makita below, which matters for storage lifting
Best Suited To
Homeowners managing larger or uneven lawns who want Honda build quality and the comfort of variable-speed self-propulsion.
Reach For A Different Pick When
The Makita DLM330Z suits you better if your lawn is small, narrow, and you want a lighter deck that stores easily in tight spaces.
The Makita DLM330Z takes a different approach with a 330mm cutting width, soft-start electronics, and a body sized for tight corners rather than wide-open lawns. It runs on the 18V LXT battery platform, which is a real advantage if your shed already holds Makita drills, saws, or trimmers, since the same batteries slide right in.
This is the pick for small urban yards, townhouse gardens, or anyone who mows a narrow strip alongside a fence. The deck pivots in tighter arcs than the 21-inch models above, and the lighter frame stores easily in a closet or balcony corner. One thing worth considering is that batteries and charger are not included, so the total cost depends on whether you already own LXT packs.
Everyday Advantages
- 330mm deck turns sharply in narrow or irregular lawn shapes
- 18V LXT platform shares batteries with the wider Makita tool family
- Compact, lighter build stores easily in small sheds or tight closets
- Soft-start feature protects the motor and extends working life
Practical Considerations
- Batteries and charger sold separately, which raises entry cost
- Smaller deck means more passes on lawns over roughly 1,000 square feet
- Less suited to thick or tall grass than wider, higher-voltage models
Feature Card
Whose Shelf It Belongs On
Urban homeowners, townhouse residents, or Makita tool owners with small, intricate lawns who value maneuverability over wide-deck speed.
A Better Fit Elsewhere
The Greenworks 80V push mower is a smarter buy for larger lawns where the 21-inch deck and included battery deliver more value.
What To Weigh Before Choosing Cordless Battery Lawn Mowers
Voltage, battery capacity, and deck size determine how a cordless mower feels in real use. Voltage (measured in volts, or “V”) drives cutting power, while amp-hours (“Ah”) indicate how long a battery lasts per charge, so a 56V 7.5Ah pack will outwork a lower-voltage unit on thick turf. Deck width shapes how many passes you need: 21-inch decks finish mid-size lawns quickly, while 13-inch decks like the Makita DLM330Z shine in narrow spaces.
Self-propelled drive is worth it for slopes or large lawns, but adds weight and cost. Push mowers like the Greenworks 80V suit flat, compact yards where extra drive feels unnecessary. Battery interchangeability across a brand ecosystem is a hidden value, especially if you already own tools from EGO, Makita, or Greenworks.
Cutting modes matter too. The Honda Versamow system handles mulching, bagging, discharge, and leaf shred without extra tools, which is genuinely useful for fall cleanup. Simpler 2-in-1 or 3-in-1 mowers do the job for routine summer cuts but require more swaps.
Finally, think about storage and lifting. Steel-deck models like the Greenworks and Honda options are heavier but more durable. Plastic or composite decks are lighter and easier to store but tend to show wear sooner. Choose based on your shed space, transport needs, and how often you mow.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Battery and charger inclusion catches many shoppers off guard. The Makita DLM330Z ships without either, so a low entry price can climb once you add compatible 18V LXT packs. Check the bundle details before assuming the listed price covers everything you need to mow on day one.
Run-time claims deserve careful reading. Manufacturers often list maximum run-time under ideal conditions, meaning a lightweight lawn with short grass. Dense, wet, or overgrown turf cuts that figure down significantly, and a second battery or larger-capacity pack may be the real path to frustration-free mowing.
When Paying More Pays Off
Higher-tier models earn their cost through torque, deck engineering, and battery ecosystem depth. The EGO LM2135SP and Honda HRX-BV deliver stronger drive systems and longer component life, which matters for weekly mowing across larger lawns. For small yards used occasionally, that premium is hard to justify. For larger or more demanding lawns, the upgrade pays back in fewer mid-season hiccups and longer service life.
Frequently Asked Questions
How long does a cordless lawn mower battery last per charge?
Run-time varies by battery capacity, grass thickness, and terrain, but most residential packs handle 30 to 60 minutes of typical mowing. Dense or wet grass reduces that window, while light, dry conditions extend it.
Are cordless mowers powerful enough for thick grass?
Higher-voltage models (56V and above) handle thick turf well, especially with brushless motors. Lower-voltage units like 18V platforms are best for routine, well-maintained lawns rather than neglected overgrowth.
Can I use one brand’s battery in another brand’s mower?
No. Battery platforms are brand-specific, and the physical slide design, voltage, and communication electronics differ between EGO, Makita, Honda, and Greenworks. Stick with one brand’s ecosystem for cross-compatibility.
How do I store a cordless mower in winter?
Store the battery indoors at moderate temperatures, ideally between 40°F and 70°F. Avoid leaving the battery in an unheated shed where extreme cold can permanently reduce its capacity.
Is self-propulsion worth the extra cost?
Self-propelled drive pays off on slopes, uneven terrain, or lawns larger than a quarter acre. For flat, small yards, a lighter push mower is easier to store and maintain at lower cost.
Closing Remarks
Cordless walk-behind mowers have closed the gap with gas in power and runtime, and the five models above cover nearly every realistic home use case. Match the deck size and drive system to your lawn’s actual shape and size, then factor in your existing tool batteries. A thoughtful match now saves years of mid-mow frustration.
