9 Best Electric Start Lawn Mower | Skip the Pull Cord Struggle

Our readers keep the lights on and the coffee maker working hard! As an Amazon Associate, I earn from qualifying purchases.

The single biggest frustration with a gas lawn mower isn’t the smoke, the noise, or the maintenance—it’s the arm-aching, shoulder-straining ritual of yanking a pull cord over and over. An electric start lawn mower erases that pain in an instant, turning the start of every mow from a gamble into a guarantee. Whether you’re facing damp morning grass or a thick lawn that needs constant attention, a reliable turn-key ignition is the upgrade that changes everything.

I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I spend my time analyzing market data, comparing specification sheets, and cross-referencing thousands of aggregated owner reports to separate genuine engineering value from marketing hype in the outdoor power equipment world.

From budget-friendly push models to premium self-propelled beasts, finding the right electric start lawn mower comes down to understanding deck construction, engine displacement, battery voltage, and how each feature set matches your specific yard conditions—not just the sticker on the box.

How To Choose The Best Electric Start Lawn Mower

Electric start removes the pull cord from the equation, but the power source behind that start button varies. A gas mower with an electric starter uses a battery-powered ignition to crank the engine, while a battery mower uses a simple push-button circuit. Your choice between gas and battery defines everything else—fuel storage, runtime profile, maintenance, and torque curve.

Power Source: Gas Starting System vs. Battery Brushless Motor

Gas electric start models like the SENIX 201cc or AMERISUN 170cc use a small 12V battery to power the starter motor. You still buy and store gasoline, but you never pull a cord. Battery mowers like the EGO POWER+ or SKIL PWR CORE use a high-voltage lithium pack to spin a brushless motor directly. No gas, no oil changes, no carburetor—just a button and a blade. The tradeoff: gas mowers deliver infinite refuel range, while battery mowers cap out at roughly 45 to 60 minutes per charge and degrade over years.

Deck Width and Construction Material

Cutting width determines how many passes you need to cover your lawn. Most residential mowers fall between 20 and 22 inches. A 21-inch deck is the standard sweet spot that balances maneuverability with speed. The material matters more than you think: stamped steel decks (PowerSmart, AMERISUN, SENIX) resist dents and hold up to rocky terrain, while polymer decks (WORX, LiTHELi) stay rust-free and reduce overall weight at the cost of long-term impact resistance. For heavily uneven yards, a heavy-gauge steel deck with reinforced weld points is non-negotiable.

Self-Propulsion: Front-Wheel vs. Rear-Wheel Drive

Self-propelled mowers save your arms but not all drive systems are equal. Front-wheel drive (FWD), found on the SENIX 170cc model, pulls the mower forward and works fine on flat, level ground. Rear-wheel drive (RWD), used by the Greenworks 48V and EGO LM2135SP, pushes the mower and gives superior traction on slopes and hills. If your yard has any incline at all, skip FWD and prioritize RWD. For completely flat lots, a push mower like the WORX WG752 cuts your cost and weight significantly without losing any cut quality.

Cutting Height Adjustment Range and Count

The number of cutting positions tells you how fine-grained your control is. Entry-level mowers offer 6 positions (typically 1.5 to 3.9 inches), which covers most warm-season grasses. Premium models like the EGO feature 8 positions ranging from 1 to 4 inches, giving you precise control for cool-season blends and seasonal transitions. Electric height adjustment, as seen on the LiTHELi, eliminates bending entirely—a genuine advantage for users with back issues or larger properties where you change heights frequently.

Battery Capacity and Platform Compatibility

For battery mowers, the voltage and amp-hour rating directly correlate to runtime and torque. A 40V system with dual 5.0Ah batteries (WORX) delivers roughly 180 watt-hours—enough for a quarter-acre on a single charge. The EGO 56V platform, with its 7.5Ah pack, provides about 420 watt-hours and supports a full ecosystem of trimmers, blowers, and chainsaws. If you already own tools from EGO, Greenworks, or SKIL, buying into that same battery platform saves hundreds of dollars on future purchases. Always check whether your mower’s battery is compatible with the brand’s other outdoor gear.

In‑Depth Reviews

Best Overall

1. EGO POWER+ LM2135SP (with Extra 5.0Ah Battery)

56V 7.5Ah + 5Ah KitSelect Cut Multi-Blade

The EGO LM2135SP sits at the apex of battery-powered electric start mowing. Its 56V platform delivers up to 7.0 ft-lbs of cutting torque—enough to challenge gas mowers on thick St. Augustine or overgrown Bermuda. The Touch Drive self-propulsion system responds to palm pressure with a scroll dial that lets you fine-tune ground speed from a crawl to a brisk walk without taking your hand off the bar. The included 7.5Ah battery handles roughly 60 minutes of continuous cutting, and the extra 5.0Ah battery effectively doubles your runtime for properties approaching half an acre.

The Select Cut multi-blade system is the defining feature. You swap the lower blade to switch between mulching, high-lift bagging, and extended runtime modes—each blade geometry optimizes airflow and cut quality for its specific task. The 21-inch stamped steel deck is built to EGO’s usual standard of rigidity, and the 8-position height adjuster gives you 1 to 4 inches of range, accommodating everything from a tight golf-green trim to tall fescue recovery. LED headlights let you finish mowing when daylight runs short.

Owners consistently report reliable push-button starts even after months of storage, with no carburetor cleaning or fuel stabilizer needed. The self-propel engages smoothly on inclines, though a few users note that the initial engagement sometimes requires a second trigger pull. Battery longevity depends on grass density and terrain—wet, thick grass will cut runtime by about 30 percent. For anyone wanting a single investment that eliminates gas entirely while matching gas-level cut quality, this is the benchmark.

What works

  • Touch Drive self-propel with variable speed is intuitive and responsive on slopes
  • Select Cut system delivers genuinely different blade performance for each mode
  • Battery platform extends to trimmers, blowers, and chain saws

What doesn’t

  • Premium price point places it above budget buyers’ reach
  • Self-propel can hesitate on first trigger pull for some users
Heavy Duty

2. SENIX 22-Inch 201cc Gas Mower

201cc OHVRear-Wheel Self-Propel

The SENIX 201cc is the gas-powered workhorse for buyers who refuse to compromise on raw displacement and infinite refuel range. With a 22-inch cutting width—the widest in this lineup—it shaves passes off your mowing time compared to standard 21-inch decks. The 201cc four-stroke OHV engine is a master of torque: it chews through 18-inch tall weeds and overgrown grass without the blade bogging down, a reality confirmed by owners who report cutting half-acre lots on a single tank of fuel.

Rear-wheel self-propulsion is the correct choice for uneven terrain. The variable-speed drive lets you match pace to grass density, and the six-position height adjuster (1.25 to 4 inches) covers the full spectrum of warm-season and cool-season mowing heights. The 1.7-bushel rear bag is generous enough to reduce emptying trips, and the 3-in-1 system lets you swap between bagging, mulching, and side discharge without tools. The steel deck is reinforced at stress points and resists the kind of rock-strike damage that would crack a polymer deck.

Where this mower stumbles is documentation and initial setup. Multiple owners report that the user manual’s font size is unnecessarily small and that the primer bulb requires far more presses than the manual suggests—often 15 instead of 3. A few units have arrived with bent adjustment hardware, and the pull-string backup can bind if the mower is stored improperly. If you can get past the learning curve, the cutting performance per dollar is exceptional. This is the mower for the person who wants gas power with an electric-start convenience button.

What works

  • 22-inch deck is the widest in this guide, cutting mowing time noticeably
  • 201cc engine has the torque to handle neglect-level overgrowth
  • Rear-wheel drive provides real traction on hills

What doesn’t

  • Primer bulb requires more presses than manual states
  • Quality control issues reported on adjustment hardware and wheel assembly
Platform Value

3. Greenworks 48V MO48L520

48V 5.0Ah x2Rear-Wheel Drive

Greenworks built the MO48L520 around its 24V battery platform, combining two 24V 5.0Ah batteries in series for a nominal 48V system. The 21-inch brushless motor is paired with a rear-wheel self-propel system that gives you variable speed control via a thumb lever—a setup that works well on moderately sloped lawns and provides enough traction to prevent wheel spin on damp grass. The included dual-port charger tops both batteries simultaneously, which matters when you’re mowing on a schedule.

The 4-in-1 cutting system adds a turbo button to the usual mulch, bag, and side-discharge options. Engaging turbo mode spikes the blade RPM for leaf pickup or extra-dense patches, and it makes a real difference when you hit a clump of wet grass that would choke a standard brushless motor. Runtime clocks in around 45 minutes combined with both batteries, which covers most quarter-acre lots comfortably. The deck height adjusts from 1 to 7 inches across 7 positions, giving you more top-end clearance than any other mower in this guide.

Owner feedback highlights two recurring issues. First, the plastic housing around the height adjustment mechanism and battery bay is thin; units have arrived with cracked casings, particularly in hot climates where the plastic becomes brittle. Second, battery life degrades noticeably after a season of heavy use, and the 1-hour cooldown requirement between discharge and recharge can stretch a mowing session across an entire weekend for larger properties. For users already invested in the Greenworks 24V tool ecosystem, this mower is a no-brainer. For new buyers, it’s a solid mid-range option with caveats about long-term durability.

What works

  • Rear-wheel drive provides real traction on inclines
  • Turbo button boosts blade speed for leaf pickup and dense grass
  • Wide height range from 1 to 7 inches covers all grass types

What doesn’t

  • Plastic housing is prone to cracking during shipping or hot weather
  • Battery performance degrades after one season; 1-hour cooldown slows recharging
Great Value

4. SENIX 170cc FWD

170cc OHVFront-Wheel Drive

The SENIX 170cc FWD is the entry point for buyers who want self-propelled convenience without stepping up to a premium gas mower. Its 170cc OHV engine generates 3.8 HP and 6.5 ft-lb of torque—enough to maintain a consistent blade speed through typical residential grass. The 21-inch stamped steel deck uses a vortex tunnel design that reduces grass buildup on the underside, a feature that saves you from having to scrape the deck clean after every mow. The 3-in-1 system handles mulching, side discharge, and rear bagging with a 1.7-bushel bag.

Front-wheel drive is the limiting factor here. On flat, well-maintained lawns, the FWD system pulls the mower forward with no complaint and makes it easy to pivot around flower beds. On any significant incline, the front wheels lose traction and the mower becomes harder to steer. The 11-inch rear wheels and 8-inch front wheels help roll over rough ground, but they can’t compensate for the fundamental traction deficit of FWD on slopes. The six-position height adjustment (1.25 to 3.75 inches) covers standard ranges, though the dual-lever system requires a bit of alignment to keep the deck level.

Owner reports are mixed but lean positive for the price point. The mower arrives mostly assembled, starts on the first attempt, and cuts evenly. The most common complaint is the same as its larger sibling: the user manual is hard to read, and the primer bulb needs more pumps than listed. A small number of units have arrived with bent height-adjustment components. For a buyer with a flat third-acre lot who wants electric start and self-propulsion at the lowest possible investment, this SENIX delivers.

What works

  • Vortex tunnel deck reduces grass buildup for cleaner operation
  • Wide 11-inch rear wheels provide stability on uneven terrain
  • Electric start with push-button or key is reliable out of the box

What doesn’t

  • Front-wheel drive loses traction on any incline
  • Primer bulb needs more presses than stated; user manual is poorly formatted
Eco Pick

5. WORX Nitro WG752

40V 5.0Ah x2AeroDeck Design

The WORX Nitro WG752 proves that a push mower can outperform self-propelled gas models when the engineering is right. The AeroDeck uses a vented cutting chamber to pull more airflow through the blade, which lifts grass before cutting and prevents clogs even in damp conditions. Paired with IntelliCut sensors that automatically dial up motor speed when the blade encounters thick grass, this mower delivers a level of cut consistency that rivals corded electric models. The brushless motor 2.0 produces 40 percent more torque than first-gen WORX motors.

The dual 20V 5.0Ah PowerShare Pro batteries combine for a 40V system—plenty for a quarter-acre lot on a single charge. The 21-inch deck is polymer, which keeps the total weight at 55.6 pounds and makes this one of the lightest 21-inch mowers available. The single-lever, 7-position height adjustment (1.5 to 4 inches) is quick to change mid-mow. The handle collapses fully for vertical storage, a real space saver for small sheds or garages. Since this is a push mower, there’s no self-propel system to maintain or repair.

The tradeoff of skipping self-propel is that you do all the pushing. For completely flat lawns, that’s a non-issue—the lightweight chassis glides easily. For any slope, even a mild one, you’ll feel the effort. Owners also note that replacement blades were hard to find at launch, though supply has improved. The PowerShare battery compatibility across 140+ WORX tools is a significant long-term value play. If your yard is flat and you want the quietest, cleanest electric start option that also saves you money, this is the pick.

What works

  • AeroDeck with IntelliCut provides exceptional cut quality and anti-clog performance
  • Lightweight at 55.6 lbs with vertical storage capability
  • Batteries work across 140+ WORX PowerShare tools

What doesn’t

  • No self-propulsion requires full pushing effort on any slope
  • Replacement blades were initially scarce, though availability is improving
Easy Setup

6. LiTHELi U20LM01

40V 4.0Ah x2Electric Height Adjustment

The LiTHELi U20LM01 carves out a unique niche: it is the only mower here with a fully electric cutting height adjustment system—no levers, no pins, no bending. A single button on the handle cycles through 6 positions from 2.5 cm to 15 cm, and the deck moves smoothly under power. For anyone with back pain, knee issues, or a general desire to avoid stooping, this feature alone justifies the purchase. The 18.5-inch deck is narrower than standard, but the tradeoff is a light 44-pound chassis that maneuvers easily through tight gates and narrow garden paths.

The Easysurge technology pushes the brushless motor to 4,100 RPM—higher than most gas mower blades spin. That blade speed translates to a clean shear cut on thick grass, and the SurgePanel display gives you real-time feedback on battery level and motor load. The self-propulsion system offers variable speeds from 1.3 MPH to 2.9 MPH, controlled by a simple dial. The T-shaped single-rod handle folds instantly for storage and makes bag attachment simple. Two 4.0Ah batteries are included, with mower slots for up to four batteries.

The runtime is the weak point. At 30 minutes combined between both batteries, this is strictly for properties under 1/6 acre—small urban lots or front lawns only. The plastic-heavy construction, while lightweight, has raised durability concerns among owners, particularly the bag attachment clips and the handle pivot points. A few users report that the self-propel system drains the battery faster than expected, cutting effective runtime further. For the right buyer—small lawn, bad back, love of convenience—this mower is a revelation.

What works

  • Electric height adjustment is genuinely life-changing for users with back problems
  • 4,100 RPM blade speed cuts cleanly through thick grass
  • Lightweight 44 lbs and narrow 18.5-inch deck for tight spaces

What doesn’t

  • 30-minute combined runtime limits use to very small lawns
  • Plastic construction raises long-term durability questions
Solid Battery

7. SKIL PWR CORE SM4910C

40V 6.0AhVariable Speed Self-Propel

The SKIL PWR CORE 40 mower brings a competitive 40V brushless system into the self-propelled space at a price that undercuts most premium battery mowers. The included 6.0Ah battery delivers up to 50 minutes of runtime according to SKIL’s testing, and real-world owner reports confirm that a quarter-acre lawn is manageable on a single charge with the self-propel used intermittently. The digital brushless motor produces consistent torque across the RPM range, and the push-button start is instantaneous—no hesitation, no priming, no fuss.

The variable-speed self-propel is controlled by a bar-mounted dial, and it gives you fine control from a slow walking pace up to a fast stroll. The 20-inch deck is slightly narrower than the industry standard, but the tradeoff is noticeably easier maneuvering in tight spots. The single-lever height adjustment offers 7 settings from 1.5 to 4 inches, covering all common grass heights. The handle telescopes and folds for vertical storage, and the weather-resistant construction means you can leave it outside under a cover without worrying about internal corrosion.

Owner feedback highlights the quiet operation—multiple users mention that no hearing protection is needed. The self-propel works even when the blade is not engaged, which helps when you’re moving the mower without cutting. The battery recall that occurred in December 2024 has been resolved, and replacements are available directly from SKIL. The mulch quality is good but not exceptional; very tall grass at the lowest height setting can cause clogs that require raising the deck. For a mid-range battery mower that includes a large-capacity battery and charger at no extra cost, the SKIL is a balanced, reliable option.

What works

  • 50-minute runtime with 6.0Ah battery covers a quarter-acre easily
  • Quiet operation eliminates need for hearing protection
  • Variable-speed self-propel gives fine control over pace

What doesn’t

  • 20-inch deck means more passes compared to 21-inch models
  • Clogging can occur on the lowest height setting with tall grass
Midsize Choice

8. AMERISUN AV8621S1

170cc OHV10-Inch Rear Wheels

The AMERISUN AV8621S1 is the self-propelled version of the gas-powered electric start formula, trading a push-only chassis for a front-wheel drive system with 10-inch rear wheels. The 170cc OHV engine provides enough torque to maintain consistent blade speed through varied grass conditions, and the 21-inch stamped steel deck is built to the same rugged spec as the PowerSmart but with the added convenience of self-propulsion. The 3-in-1 system (mulch, bag, side discharge) covers all standard mowing modes, and the 1.4-bushel grass catcher is adequate for most mid-size yards.

The high-wheel design is the standout feature here. The 10-inch rear wheels and 7-inch front wheels create significant ground clearance, letting the mower glide over ruts, roots, and uneven patches without scraping the deck. The six-position dual-lever height adjustment (1.5 to 3.9 inches) mirrors the PowerSmart’s range. Assembly is minimal—attach the handle, add oil and gas, and you’re mowing. The foldable handle reduces storage footprint, though the mower remains relatively compact even when fully assembled.

Quality control is the main concern. Multiple owners report that the self-propulsion system can exhibit uneven engagement, and there are documented instances of wheels arriving cracked or broken. The height adjustment levers use small screws and nuts that can vibrate loose over time, causing the deck to drift lower during a mow. Customer service responsiveness varies. For buyers who can accept the potential for initial defects and are comfortable with minor DIY fixes, the engine performance and wheel design deliver strong value for the price.

What works

  • 10-inch rear wheels provide excellent ground clearance for uneven terrain
  • 170cc engine starts reliably with electric ignition
  • Quick assembly and foldable handle for easy storage

What doesn’t

  • Wheel and adjustment hardware durability is inconsistent
  • Customer service response can be slow for warranty claims
Budget Pick

9. PowerSmart EasyGlide DV8621P

144cc OHVAuto-Choke Start

The PowerSmart EasyGlide DV8621P is the entry-level gas mower that proves you don’t need to spend much to get electric start reliability. At 61.6 pounds and powered by a 144cc four-stroke OHV engine, this is the lightest gas push mower in the lineup. The auto-choke system eliminates the usual primer-and-throttle dance: you push the start button, and the motor fires on the first or second revolution. The 21-inch steel deck uses a stamped construction that handles moderate wear without issue, and the 3-in-1 mulching, bagging, and side-discharge system covers every standard mowing scenario.

The dual-lever, six-position height adjustment lets you choose from 1.5 to 3.9 inches in discrete increments. The 8-inch rear and 7-inch front double ball-bearing wheels roll smoothly even on bumpy terrain, and the mower’s light weight makes it easy to push up mild inclines. Assembly takes under 20 minutes out of the box—attach the handle, mount the grass bag, and add oil and fuel. Owners consistently report that the cutting performance handles thick grass without bogging, and that the blade leaves a clean, even cut.

The tradeoffs are typical of budget gas mowers. The fuel tank is small—owners with lots over a quarter-acre report needing a mid-mow refill. The foam grip on the handle can arrive damaged. And while the engine starts reliably, the overall build quality uses thinner-gauge steel than premium mowers, so this is not a purchase for heavy commercial use or rocky terrain. For the budget-conscious buyer who wants electric start, a steel deck, and simple push operation, the PowerSmart is hard to beat on price.

What works

  • Auto-choke electric start fires reliably on first attempt
  • Lightweight 61.6 lbs makes it easy to push and maneuver
  • 21-inch steel deck provides solid cutting width for the price

What doesn’t

  • Small fuel tank requires refueling mid-mow for larger lots
  • Thinner steel deck and foam grip reduce long-term durability

Hardware & Specs Guide

Engine Displacement vs. Torque Curve

Gas mower engines are measured in cubic centimeters (cc) of displacement. A 144cc engine (PowerSmart) produces roughly 3.0 to 3.5 HP, which is adequate for weekly mows on thin-bladed grasses like fescue. A 201cc engine (SENIX) pushes 4.0+ HP and maintains blade speed through thick, wet grass without bogging. Larger displacement also adds weight—about 10 pounds per 50cc—which affects handling. For battery mowers, torque is measured in Newton-meters or foot-pounds. The EGO 56V motor delivers 7.0 ft-lbs, which exceeds most 170cc gas engines in real-world cutting tests. The key metric is not peak torque but sustained torque under load—brushless motors maintain full torque across their RPM range, while gas engines peak at specific RPM and fall off.

Battery Voltage and Amp-Hour Math

Battery mowers are marketed by voltage (40V, 48V, 56V), but the real energy capacity is voltage × amp-hours = watt-hours. A 40V 5.0Ah battery (SKIL) delivers 200 watt-hours. A 56V 7.5Ah battery (EGO) delivers 420 watt-hours—more than double. Runtime scales linearly with watt-hours, but grass density, slope, and self-propel usage all draw power non-linearly. For a quarter-acre lot, target at least 300 watt-hours of total battery capacity. For half-acre lots, you need 500+ watt-hours or two batteries. The number of batteries included matters less than the total watt-hours. A dual-battery 40V setup (WORX) with two 5.0Ah packs equals 400 watt-hours, which is competitive with a single high-voltage pack.

Deck Material and Airflow Design

Stamped steel decks (PowerSmart, AMERISUN, SENIX, EGO) offer impact resistance and rigidity. Polymer decks (WORX, LiTHELi) eliminate rust and reduce weight but can crack under stress. The critical spec is deck depth: deeper decks (typically 3.5 to 4.5 inches) generate more vacuum, which lifts grass before cutting for a cleaner result. Aerodeck or vortex tunnel designs (WORX, SENIX) add vent channels that prevent clippings from accumulating inside the deck. Regardless of material, the blade tip speed—measured in feet per minute—determines cut quality. Most gas mowers spin at approximately 19,000 feet per minute; battery mowers at 13,000 to 16,000 FPM. Higher tip speed means less tearing and a cleaner cut.

Self-Propulsion Drive Systems

Self-propelled mowers use either a friction disk or gear transmission to drive the wheels. Front-wheel drive (FWD) is cheaper and lighter but loses traction on slopes because the front wheels carry less weight. Rear-wheel drive (RWD) pushes the mower from behind, keeping the drive wheels weighted under the engine/battery and operator for superior hill grip. Variable-speed self-propel (EGO, SKIL) uses a sensor to match ground speed to walking pace automatically. Single-speed self-propel (AMERISUN, SENIX FWD) requires manual speed selection. RWD systems add about 5 to 8 pounds to the mower weight. For any yard with a slope greater than 10 degrees, RWD is not optional—it’s the only system that works effectively.

FAQ

Is electric start on a gas mower worth the extra cost compared to a pull cord?
Yes, if you mow frequently or have physical limitations. A pull-cord mower costs slightly less upfront, but the electric start system uses a small battery to crank the engine instantly—no yanking, no flooding, no arm fatigue. On a typical gas mower, the electric start mechanism adds roughly 5 to 10 pounds of weight and requires a small battery that needs replacement every 2 to 4 years. For anyone who stores their mower for long periods or starts it in cold weather, the convenience is transformative.
How long does the starter battery last on a gas electric start mower?
The 12V starter battery in a gas mower typically lasts 2 to 4 years depending on storage conditions. If you store the mower in a heated garage and use it regularly, the battery may last longer. Cold storage and long idle periods drain the battery faster. Most gas electric start mowers include a charging alternator that recharges the battery while the engine runs, so the battery only needs replacement when it can no longer hold a charge. Keep the battery terminals clean and use a trickle charger during off-season storage for maximum life.
Can I use an electric start battery mower if I have a large yard over half an acre?
Yes, but you need sufficient battery capacity. For half-acre yards, target a mower with at least 500 watt-hours of total battery capacity (e.g., a 56V 7.5Ah battery equals 420 watt-hours, which nearly covers a half-acre with careful self-propel use). Many owners of large lots buy a second battery and swap mid-mow. The EGO LM2135SP with the extra 5.0Ah battery bundle effectively gives you 840 watt-hours, which handles a full half-acre without recharging. Gas mowers remain the unrestricted option for large properties because refueling takes seconds.
What maintenance does an electric start battery mower require compared to gas?
Battery mowers require dramatically less maintenance. There is no engine oil to change, no spark plug to replace, no air filter to clean, no carburetor to adjust, and no fuel stabilizer to add. The only regular maintenance tasks are: sharpening or replacing the blade every 1 to 2 seasons, cleaning the deck underside after each mow to prevent grass buildup, and storing the batteries at a moderate temperature (ideally 40 to 80 degrees Fahrenheit) when not in use. Gas electric start mowers need all the standard gas engine maintenance plus occasional battery terminal cleaning.
Does a narrower 20-inch deck significantly increase mowing time compared to a 22-inch?
For small lawns, the difference is negligible—about 5 percent more passes on a quarter-acre. For large lawns, the time adds up. A 22-inch deck covers roughly 10 percent more ground per pass than a 20-inch deck, so on a half-acre lawn, you save about 10 to 15 minutes of walking. The tradeoff is that narrower decks are lighter and more maneuverable around obstacles. If your yard has many flower beds, trees, or tight corners, a 20-inch mower may actually be faster overall because you spend less time maneuvering. For open rectangular lots, go with the widest deck you can afford.

Final Thoughts: The Verdict

For most gardeners, the electric start lawn mower winner is the EGO POWER+ LM2135SP because it combines gas-rivaling torque with a mature battery platform, rear-wheel self-propel, and a genuine multi-blade cutting system that adapts to season and grass type. If you need unlimited range and raw displacement for overgrown properties, grab the SENIX 22-Inch 201cc. And for a flat, eco-conscious yard where you want the quietest, lightest electric start mower with expandable battery compatibility, nothing beats the WORX Nitro WG752.
