6 Best Electric Mulching Lawn Mowers

Ditching gas means quieter weekends, zero oil changes, and a garage that no longer smells like a service station. Cordless mowers have grown up fast, and today’s models handle real lawns, not just postage-stamp yards. The trick is matching deck size, battery runtime, and push-versus-self-propelled drive to the grass you actually have.

A Breakdown Of The Leading Choices

The Greenworks 80V pushes into territory where cordless mowers used to stall. Its 80-volt brushless motor delivers the kind of torque that chews through thick spring growth without bogging down, and the 21-inch steel deck covers ground fast. You get a 4.0Ah battery plus a rapid charger that tops it off in roughly an hour, which is handy for back-to-back mow days.

For suburban lots sitting around a quarter acre, this lands in the sweet spot. The single-lever height adjustment lets you move between cutting heights without fumbling at each wheel, and the brushless design tends to outlast older brushed motors. It’s the pick for homeowners who want gas-like cutting feel without the maintenance headaches.

What Pays Off

  • The 80V system delivers noticeably more torque than typical 40V mowers in dense patches.
  • The 21-inch steel deck trims mowing sessions on open lawn areas compared to a 17-inch deck.
  • Rapid charging in around 60 minutes keeps downtime minimal between sessions.
  • A brushless motor (a design with no internal friction brushes, lasting longer and running quieter) typically extends service life over brushed units.
  • Single-lever height adjustment simplifies switching between grass types and seasonal cuts.

Things To Consider

  • At full pace in tall grass, runtime may dip below the 60-minute ceiling the spec sheet suggests.
  • The steel deck adds weight versus plastic-deck rivals, which can tire out smaller operators on slopes.

Who It Suits Best

Suburban homeowners with mid-sized lawns who want cordless convenience without giving up cutting muscle.

Consider Something Else When

Tight city plots with narrow gates and lots of obstacles are a better match for the lighter Worx WG733.1.

Casince quietly built a 17-inch cordless mower that overdelivers for the price. It runs on two 20V 4.0Ah batteries working in tandem, which extends runtime and lets you swap one out while the other keeps mowing. Six height positions from about 1 to 3 inches give you the kind of flexibility you usually see on more expensive units.

This is the sensible pick for first-time cordless owners or anyone with a small yard who doesn’t need the brute force of an 80V system. Owners commonly report it handles weekly cuts with room to spare on a typical suburban lot. For shoppers focused on value without abandoning core features, it deserves a serious look.

Why It Works Well

  • Dual 20V batteries stretch runtime past single-battery rivals in the same class.
  • Six height positions cover everything from cool-season grass to thicker summer growth.
  • The 17-inch deck balances maneuverability in tight spaces with reasonable cutting width.
  • Two-battery setup lets you rotate packs for longer mowing sessions.

Worth Noting

  • Brushless motors typically last longer than brushed alternatives, and this unit’s motor type isn’t specified here.
  • At wide-open throttle in damp grass, you may notice some power drop compared to higher-voltage picks.
  • The included collection bag tends to fill fast during peak growth, so plan to empty more often.

Made For

Small to medium yard owners shopping for a budget cordless mower without surrendering useful features.

Look Elsewhere When

You have a quarter acre or larger and want a wider deck for fewer passes, in which case the Worx WG745 makes more sense.

The WG733.1 is the smallest, lightest option in the Worx lineup, and that matters when you’re wrestling a mower through narrow side yards or up basement stairs for storage. A brushless motor and a 20V 5.0Ah PowerShare battery push it into territory where some compact mowers simply stall out.

Realistically, this covers lawns up to roughly 3,200 square feet on a single charge under typical conditions. The 14-inch deck keeps the unit compact enough for tight gates, and the PowerShare battery works across more than 140 Worx tools if you’re already in that ecosystem. For city dwellers with postage-stamp lawns, it’s a refreshingly manageable machine.

Standout Benefits

  • Lightweight build makes storage and pushing noticeably easier than full-size mowers.
  • The 20V 5.0Ah PowerShare battery works across a wide range of Worx tools, an upgrade path for existing owners.
  • Brushless motor extends runtime and tends to outlast brushed designs.
  • Compact 14-inch deck slips through gates and tight side yards without hassle.

Trade Offs

  • A 14-inch deck means more passes on open lawn compared to 17 or 21-inch rivals.
  • In dense, tall grass, you may find yourself making slower passes to avoid bogging.

Best Suited To

Apartment dwellers and small-yard homeowners who prioritize light weight and easy storage over wide-deck speed.

Not Your Match When

You maintain a lawn above 3,500 square feet, in which case the Greenworks 80V offers the runtime and deck width to match.

The WG735 steps up to 40 volts and adds IntelliCut, a torque-sensing system that automatically adjusts power output based on grass density, a feature that quietly solves one of the most common frustrations for new cordless mower owners. In thin patches it conserves battery, and in thick spots it ramps up without you thinking about it.

Paired with a 20V 4.0Ah battery, it covers lawns up to about 1/8 acre on a single charge. The optimized deck with Airflow technology lifts grass for a cleaner cut, and the 2-in-1 design lets you mulch or bag depending on the season. For homeowners who don’t want to fiddle with manual power adjustments, this handles the variability for you.

What Earns Its Place

  • IntelliCut takes the guesswork out of switching modes as grass density changes across your yard.
  • Airflow-optimized deck lifts blades for a noticeably cleaner cut finish.
  • 2-in-1 mulching and bagging flexibility covers most seasonal preferences.
  • 40V platform delivers more usable power than 20V units without jumping to the heaviest tier.

Room For Improvement

  • The 14-inch deck still means more passes than wider alternatives on open lawn areas.
  • Single-battery design limits runtime extension without a second pack on hand.

Who Will Love This

First-time cordless mower owners with mixed grass conditions who want the mower to handle power adjustments automatically.

A Better Fit Elsewhere

Larger lawns where deck width matters more than automatic adjustment are a stronger match for the EGO POWER+ LM2135SP.

The WG745 doubles down on what made the WG735 appealing, then widens the deck to 17 inches and adds a second battery. Two 20V 4.0Ah PowerShare packs running in parallel keep you mowing through larger yards without forced breaks, and the dual charger tops both off faster than charging them sequentially.

It’s rated for lawns up to 1/4 acre, which covers a meaningful slice of suburban properties. PowerShare compatibility again pays off if you already own other Worx tools, since these batteries slide straight into string trimmers, blowers, and the rest of the lineup. For frequent mowers who treat lawn care as a weekly ritual rather than an occasional chore, this is the sweet spot.

Bright Spots

  • Two included 20V 4.0Ah batteries stretch runtime to cover a quarter acre confidently.
  • 17-inch deck splits the difference between compact agility and wide-pass efficiency.
  • Dual charger rejuices both packs at once, cutting downtime between sessions.
  • PowerShare batteries slot into 140+ Worx tools, expanding your cordless tool ecosystem.
  • Brushless motor design adds longevity and quieter operation over brushed alternatives.

Points To Keep In Mind

  • Battery charging generates heat in warm sheds, so store the charger in a ventilated spot.
  • The 40V platform is heavier than the WG733.1, which matters if you’re navigating stairs for storage.

Perfect Match For

Homeowners with quarter-acre lawns who mow weekly and want extended runtime without stepping up to a self-propelled model.

Reach For A Different Pick When

Sloped terrain or thick, tall grass regularly pushes your mowing time past 45 minutes, where the EGO POWER+ self-propelled system takes strain off your legs.

EGO’s LM2135SP sits at the top of the cordless food chain for a reason. The 56V 7.5Ah battery delivers up to 7.0 ft-lbs of torque, which the brand equates with gas-mower-level performance, and the self-propelled drive takes the leg work out of slopes and thick turf. You also get a second 5.0Ah battery in the bundle, effectively doubling your session capacity.

The Select Cut Multi-Blade system ships with three interchangeable lower blades for mulching, bagging, or extended runtime, and the mulching blade comes installed for most users. This is the mower for anyone who has graduated from basic cordless models and wants the closest thing to a gas replacement without the gas. It’s also a significant step up from the WG745 in both deck width and power.

Everyday Wins

  • Self-propelled drive reduces fatigue on slopes and larger lawns.
  • The Select Cut blade system lets you swap between mulching, bagging, or runtime-optimized cuts.
  • Two included batteries (7.5Ah plus 5.0Ah) effectively double your working session.
  • 56V platform delivers the highest torque output in this roundup.
  • 21-inch deck covers wide swaths fast on open lawn areas.

Some Limits To Know

  • The extra battery ships separately, so plan for a staggered arrival.
  • Self-propelled models weigh more than push mowers, which can challenge smaller operators on uneven terrain.

Built With In Mind

Homeowners with larger or sloped lawns who want cordless simplicity without sacrificing the muscle and drive of a gas machine.

Swap It Out When

Your yard is small and flat, in which case the Casince offers similar mulching flexibility at a much lower entry point.

What To Weigh Before Picking Your Mower

Deck size determines how many passes you make. A 14-inch deck handles tight spaces but doubles your trip count on open lawn, while a 21-inch deck chews through wide yards fast but won’t fit narrow gates. Most suburban lots between 1/8 and 1/4 acre land comfortably on a 17 to 21-inch deck.

Battery platform matters more than people expect. Higher voltage systems (56V or 80V) deliver more torque for thick grass, while 20V and 40V platforms offer lighter weight and lower cost. Check whether batteries share compatibility with other tools you own; Worx’s PowerShare ecosystem, for example, lets one set of batteries cover mowers, trimmers, and blowers.

Self-propelled drive earns its keep on slopes or in yards above a quarter acre. For flat, smaller lots, a push mower keeps weight and cost down. Mulching capability (where cut grass is recirculated and shredded back into the lawn as natural fertilizer) is now standard across this category, but blade design varies; multi-blade systems like EGO’s Select Cut let you tune the cut to your preference.

Smart Trade-Offs Across This Category

Mistakes Worth Dodging

The most common slip-up is buying by deck size alone and ignoring battery voltage. A 21-inch deck on a weak 20V platform bogs down in spring growth, while a smaller 17-inch deck on a 56V system handles the same grass without complaint. Match the voltage to your grass type, not just the size of your yard.

What The Higher Tier Buys

Premium models like the EGO POWER+ LM2135SP cost more for three reasons: self-propelled drive, higher-voltage batteries, and interchangeable blade systems. You’re paying for less fatigue, more torque, and finer control over cut quality. For flat, small yards, those gains rarely justify the jump; for sloped or half-acre lawns, the upgrade pays for itself in saved time and energy.

Frequently Asked Questions

How long do cordless mower batteries typically last? Most lithium-ion battery packs deliver around 3 to 5 years of regular use before noticeable capacity loss. Storage in a cool, dry shed during off-season months extends their working life.

Can cordless mowers handle wet grass? Most manufacturers recommend mowing dry grass for the cleanest cut and longest runtime. Wet grass clumps under the deck, strains the motor, and reduces battery life per charge, so waiting for a dry window is worth it.

Is mulching better than bagging for lawn health? Mulching returns finely shredded clippings to the soil, feeding the lawn naturally over time. Bagging keeps the lawn looking tidier and is useful during peak growth or disease flare-ups, but it removes nutrients you’d otherwise recycle.

Do I need self-propelled drive? Self-propelled drive makes sense for sloped lots, larger yards above a quarter acre, or anyone with mobility concerns. On flat, smaller lawns, a push mower is lighter, simpler, and less expensive.

How long does it take to charge a cordless mower battery? Most rapid chargers refill a depleted pack in 30 to 60 minutes. Standard chargers can take 2 to 3 times longer, so check whether your pick includes a rapid charger before you commit.

The Takeaway

Cordless mowers have earned their place in the shed. Match the voltage and deck size to your lawn, decide whether self-propelled drive matters, and you’ll spend your weekends mowing instead of maintaining an engine. Any of these six will treat your grass well; the right one just depends on the yard you have.
