A Breakdown Of The Leading Choices
The Greenworks 80V platform has been a long-running favorite in the cordless category, and the 21-inch push version remains a sensible anchor pick for suburban lots up to roughly a third of an acre. Its steel deck holds up to seasonal bumps, and the brushless motor (a motor without internal brushes, which means less friction and a longer service life) keeps noise low enough that you can mow early on a Saturday without complaints from the neighbors.
Where this mower pulls ahead of entry-level battery models is in the single-lever height adjust and the 80V 4.0Ah pack, which charges in about an hour on the included rapid charger. Compared to the EGO LM2114 coming up next, Greenworks leans toward a sturdier feel in the hand, though it lacks the torque numbers EGO markets for tall fescue and similar dense grasses.
Advantages To Know
- Up to 60 minutes of runtime from the 4.0Ah pack, enough for most small-to-mid suburban lawns on a single charge.
- Steel deck resists dings and warping from hidden roots and rocks over many seasons.
- Brushless motor keeps operating volume low and reduces wear on internal parts.
- Single-lever height adjustment speeds up changes between thick and patchy zones.
- Rapid charger refills the battery in roughly an hour, handy for two-stage yards.
Trade Offs
- No self-propelled drive, so sloped lawns can feel like a workout by the back row.
- Real-world runtime drops noticeably in dense or wet grass compared with the published figure.
Who It Suits Best
Homeowners with flat-to-gently-sloped lawns under about a third of an acre who want a durable cordless platform without paying for premium Honda or EGO pricing.
Consider Something Else When
The EGO POWER+ 21″ Cordless Electric Lawn Mower LM2114 is a better fit for anyone with thicker turf who wants stronger cutting torque from the same 21-inch footprint.
EGO’s LM2114 is the 56V platform trimmed down to push-mower simplicity, and the torque output is its calling card. The included 6.0Ah battery pairs with a brushless motor that produces enough cutting force to push through tall spring growth and damp morning grass without bogging down.
For households with mixed turf types, the seven-position height range (about 1 to 4 inches) covers everything from a clean golf-green cut to leaving the lawn longer through July. The fold-flat handle keeps the footprint small in a garage corner, and in our view the LM2114 sits in a useful middle ground between entry-level battery units and the more expensive self-propelled LM2135SP covered later.
Notable Upsides
- Up to 55 minutes of runtime from the 56V 6.0Ah pack, useful for mid-size lots.
- Six foot-pounds of cutting torque handles tall, thick, or damp grass without stalling.
- Seven height positions offer a wider range than most 21-inch push mowers at this tier.
- Brushless motor design reduces routine maintenance and extends service life.
Points To Keep In Mind
- It is a push mower only, so the rear wheels carry all the effort on inclines.
- 56V batteries and chargers from EGO cost more to replace than 40V alternatives if a pack fails years down the line.
Feature Snapshot
Made For
Homeowners with thick, fast-growing turf who want gas-like cutting power without the noise, fumes, or pull-start routine.
Look Elsewhere When
The EGO POWER+ Self-Propelled LM2135SP with Extra Battery is the smarter choice for anyone with sloped ground or a larger yard where walking effort starts to matter.
Stepping up from the LM2114, the LM2135SP adds the feature most people eventually wish they had on a cordless mower: rear-wheel self-propulsion. The 7.5Ah primary pack, plus a 5.0Ah spare, means you can swap and keep going on a larger lot without waiting on a recharge, which is a real time-saver on weekend mornings.
The Select Cut multi-blade system lets you swap the lower blade to match the job. One blade is tuned for mulching, another for high-lift bagging, and a third for extended runtime. For a household that bags in spring and mulches through summer, that flexibility pays off over a single season of mixed mowing conditions.
Strong Points
- Self-propelled drive takes the strain off hilly or uneven lawns.
- Dual batteries (7.5Ah plus 5.0Ah) extend effective mowing time well past an hour.
- Select Cut multi-blade system adapts to mulching, bagging, or extended runtime.
- Up to 7 foot-pounds of cutting torque for the densest patches of cool-season grass.
- Rapid charger refills the main pack faster than standard EGO chargers.
Honest Caveats
- Heavier than the push-only LM2114, which can be a factor when lifting into a truck bed.
- Premium price reflects the bundle, and the extra 5.0Ah battery ships separately.
Best Suited To
Homeowners with half-acre-plus yards, slopes, or anyone who wants one battery to mow and another ready to swap in for trimming or blowing.
Swap It Out When
The Honda HRX-BV 21″ Walk Behind Battery Mower HRX217YXBVKA4 is worth a look for shoppers who prefer Honda’s variable-speed drive feel and don’t need EGO’s battery ecosystem.
Honda’s HRX line has a long reputation among homeowners who care about cut quality, and the HRX-BE brings that DNA to the battery side. The standout here is the Versamow system with Clip Director, a built-in lever that lets you shift between mulching, bagging, discharging, and leaf-shredding without swapping attachments. For anyone who bags in spring and mulches in fall, that’s a real workflow improvement.
Unlike the EGO LM2114, which prioritizes raw torque, the HRX-BE leans into Honda’s traditional strengths: a refined cut and a deck design that handles wet clippings without clumping. The trade-off is weight and price, both of which sit above the EGO models in this list.
Practical Pluses
- 4-in-1 Versamow with Clip Director switches modes without extra attachments.
- Twin-blade MicroCut system produces finer clippings for cleaner bagging and mulching.
- Honda’s GCV-derived motor architecture maintains RPMs under load.
- 21-inch deck matches the EGO models for coverage per pass.
- Sturdy construction tends to outlast entry-level battery platforms.
Some Limits To Know
- Push-only drive, so the Honda variable-speed HRX-BV may suit sloped lots better.
- Sits at a higher price tier than most cordless 21-inch mowers in this lineup.
Quick Facts
Who Will Love This
Homeowners who bag and mulch across the season and want a single mower that handles both without swapping hardware.
Reach For A Different Pick When
The EGO POWER+ Self-Propelled LM2135SP with Extra Battery makes more sense for anyone with a sloped yard who needs driven rear wheels rather than a push-only Honda.
The HRX-BV is the variable-speed sibling of the HRX-BE, and the addition of a cruise-control-style drive system changes the experience on anything beyond a flat rectangle. Where the push-only Honda demands effort, this one lets you set a pace and walk behind it, which matters once the lawn stretches past a quarter acre.
You still get the 4-in-1 Versamow deck and twin-blade MicroCut system, so bag and mulch quality match the HRX-BE. The variable-speed drive is the main differentiator, paired with a slightly heavier chassis that anchors the mower on uneven ground.
The Helpful Details
- Variable-speed self-propelled drive reduces fatigue on larger or hilly lawns.
- Versamow 4-in-1 system covers mulching, bagging, discharge, and leaf-shred.
- Twin-blade MicroCut deck refines clippings for cleaner bag fills.
Less Ideal Details
- Heavier than push-only Hondas, which complicates lifting into a storage shed loft.
- Battery runtime lands below the EGO LM2135SP bundle, so larger yards may need a mid-mow swap.
Right Fit For
Honda loyalists with bigger or uneven yards who want the brand’s deck engineering without giving up variable-speed drive.
Where A Sibling Pick Shines
The EGO POWER+ Self-Propelled LM2135SP with Extra Battery suits shoppers who value longer total runtime over Honda’s deck feel, especially on lots that push past half an acre.
Litheli slots into the budget-conscious side of cordless mowing, and the 16-inch model is a sensible pick for smaller yards where a 21-inch deck is overkill. The 50L collection bag is genuinely larger than what most mowers in this size class offer, which means fewer trips to the compost bin on a full mow.
Six height positions from 25 to 75mm (roughly 1 to 3 inches) cover most seasonal preferences. The dual 5.0Ah battery system keeps voltage steady across the full drain, which is the real reason this mower feels peppier than older 40V designs. For shoppers who don’t need premium brand backing, the math works.
A Few Strong Suits
- Dual 5.0Ah battery setup maintains consistent 40V output from full to empty.
- 50L collection bag holds more clippings than typical 16-inch mowers.
- Six height positions from 25 to 75mm suit common grass types.
- Brushless motor design keeps the price closer to budget tier than premium 56V options.
Where It May Fall Short
- 16-inch deck means more passes on larger lots, so the 21-inch Greenworks or EGO models may be faster.
- Both batteries must be inserted to operate, which means no quick single-pack swaps.
Feature Rundown
Whose Shelf It Belongs On
Budget-focused shoppers with small-to-mid suburban lawns who want a brushless battery platform without the cost of premium 56V or Honda options.
Skip It When
The Greenworks 80V 21in Push Lawn Mower 4.0Ah is the better choice for anyone with a wider lawn who would rather make fewer passes.
The 14-inch Litheli fills a niche the rest of this list mostly ignores: tiny lawns, courtyard gardens, and anyone who needs a mower that disappears into a closet. The fold-flat handle and light chassis make it easy to carry up apartment stairs or hang on a garage wall.
You give up deck width and some of the runtime of larger models, but for a yard under 1,500 square feet, the 5.0Ah pack covers the whole job in one go. The brushless motor keeps the noise profile low enough for early-morning sessions in dense neighborhoods.
Real Benefits
- Lightweight design makes it manageable for seniors or anyone who struggles with heavier mowers.
- Quick-fold handle shrinks the footprint for tight garage or shed storage.
- Brushless motor runs quietly, ideal for noise-restricted neighborhoods.
- Five height positions from 1 to 2.5 inches cover most common small-lawn preferences.
Practical Considerations
- 14-inch deck needs more passes than the 16-inch Litheli on even modestly larger yards.
- Single-battery design means no runtime extension via pack swap mid-mow.
Feature Card
Perfect Match For
Apartment dwellers with shared courtyard lawns, seniors managing small lots, or anyone whose storage space can’t fit a full-size mower.
A Better Fit Elsewhere
The Litheli 40V 16″ Cordless Lawn Mower 50L Bag suits shoppers with a bit more yard who want a larger bag and dual batteries for longer sessions.
What Matters Most Before Choosing Bagging Push Lawn Mowers
Deck Size And Yard Footprint
The 21-inch decks on the Greenworks, both EGOs, and both Hondas are the right size for most quarter-acre-to-half-acre lawns, finishing a mow in fewer passes. The Litheli 16-inch splits the difference for smaller suburban lots, while the 14-inch is built for courtyards and tight side yards under about 1,500 square feet. Wider decks save time but cost more and add weight.
Battery Platform And Runtime
Voltage (the electrical “pressure” pushing power through the motor) and amp-hours (the size of the fuel tank, essentially) both shape real-world runtime. A 56V or 80V system like EGO and Greenworks offers stronger torque for thick grass, while 40V Litheli platforms handle routine mowing at lower cost. Self-propelled models, like the EGO LM2135SP and Honda HRX-BV, drain packs faster than push-only units, so dual batteries or a higher amp-hour pack matters on larger lots.
Drive Type And Terrain
Push-only mowers work on flat lawns and small yards, but anything with a slope or uneven ground benefits from a self-propelled or variable-speed drive. The EGO LM2135SP and Honda HRX-BV both take the effort out of inclines. Worth noting though, self-propelled mowers add noticeable weight, which affects lifting and storage.
Bagging Vs Mulching Flexibility
Honda’s Versamow system with Clip Director is the most flexible in this list, shifting between bag, mulch, discharge, and leaf-shred mid-mow. EGO’s Select Cut multi-blade system on the LM2135SP swaps blades to optimize for bagging, mulching, or runtime. Most others offer two or three modes and require bag or mulch plug swaps.
Key Considerations Across These Picks
Common Shopping Slip Ups
The most common mistake is sizing a mower to the lawn as it looks today, not as it will look in two years when the new landscaping fills in and the yard feels twice as long. Buyers also tend to focus on deck width and overlook battery platform, only to discover mid-season that a replacement pack costs as much as a budget mower. Finally, push-only mowers look appealing in the driveway, then feel heavy by the third row of any slope, so matching drive type to terrain matters more than spec sheets suggest.
What Separates Premium From Basic
Premium picks like the Honda HRX-BV and EGO LM2135SP earn their price through variable-speed or self-propelled drives, dual-battery systems, and deck features such as Versamow or Select Cut. The upgrade makes sense for larger yards, sloped terrain, or households that switch between bagging and mulching through the year. For flat, smaller lots, a push-only mid-tier unit like the Greenworks 80V or Litheli 16-inch covers the same job without the extra cost or weight.
Frequently Asked Questions
How long does a cordless push mower actually run on one charge?
Most 56V and 80V mowers in this category deliver 45 to 60 minutes of runtime under normal conditions, though thick or wet grass can cut that by a third. Dual-battery bundles like the EGO LM2135SP extend effective runtime past an hour by allowing mid-mow swaps.
Are bagging push mowers hard to push uphill?
Push-only models require real effort on inclines, which is where self-propelled drives like the EGO LM2135SP and Honda HRX-BV pay off. The motor drives the rear wheels, so you only need to steer and balance rather than push the full weight forward.
Can a 14-inch mower really handle a normal yard?
A 14-inch deck works well for lawns under about 1,500 square feet, but anything bigger means noticeably more passes than a 16-inch or 21-inch model. For most suburban lots, stepping up to 16 or 21 inches saves meaningful time each mow.
What’s the difference between mulching and bagging modes?
Mulching chops clippings finely and drops them back into the lawn as natural fertilizer, while bagging collects clippings in a rear bag for disposal or composting. Honda’s Versamow system can blend the two, sending a portion to the bag and the rest back to the turf.
How do I store a cordless mower in a small shed?
Look for models with fold-flat handles, like both Litheli picks and the EGO LM2114, which collapse vertically to reduce footprint. Storing the battery separately in a climate-controlled spot also extends pack life through winter.
Wrap Up
A 21-inch battery platform covers the widest range of suburban lawns, while 16-inch and 14-inch decks earn their place in tight quarters. Match drive type to your terrain, decide between mulching and bagging flexibility, and pick a battery platform that won’t strand you mid-mow. The right pick depends less on spec sheet wins and more on the shape and slope of your yard.
