Best Lightweight Elctric Start Self Propelled Lawn Mower Review
Greenworks 40V Compact Store – Best Easy Storage
Punchy and practical, the Greenworks 40V 21′ stands out for its rear-wheel-drive self-propel system and brushless motor that delivers strong torque without the noise of gas. The 21-inch steel deck covers ground quickly, while the 3-in-1 system (mulch, bag, side discharge) adapts to yard needs. A single-lever 7-position height adjust solves the most common mowing pain point: dialing in cut height fast for different grass conditions.
In testing, this mower handled suburban lawns with mixed turf and mild slopes with confidence, thanks to its rear-wheel traction. The included 5.0Ah battery offers up to roughly 45 minutes in average grass; dense or wet turf trims that, but the brushless drive remains efficient. It’s sturdy yet easy to maneuver, though very tall or thick spring growth may require slower passes to prevent bogging.
Compared with the Litheli 18′ model, the Greenworks 40V offers a wider deck and better traction, making it a fit for medium yards that need fewer passes. Against the MightyMow 40V 21′, it’s a bit lighter and simpler, but can’t match dual‑battery endurance. Ideal for homeowners wanting electric start convenience and self-propel ease with compact storage, especially given its vertical storage design; it offers stronger all-around capability than the Litheli while staying lighter-duty than the Greenworks 60V.
- Vertical storage
- Rear-wheel drive
- 21′ steel deck
- 7-height adjust
- 3-in-1 cutting
- Runtime drops in thick grass
- Limited in tall, wet growth
Litheli 18\” Variable Speed – Best Small Yards
Featherlight and nimble, the Litheli 18′ is built for users who prioritize low weight and effortless maneuverability with electric start simplicity. Its brushless motor and variable self-propel (1.3–2.9 MPH) make tight turns and small-lawn edges easy. The 6-position height adjust (0.98’–2.95′) suits short, tidy cuts—great for regularly maintained grass.
In the yard, it excels on small, flat plots and trim passes around landscaping. The 18-inch deck keeps it agile, and the 10.57-gal bag means fewer trips than typical small mowers. Expect around 30+ minutes per charge from the included 2x20V 4.0Ah batteries; in longer or thicker grass, pace control helps, but the lower max cut height and narrower deck mean more passes.
Compared with the Greenworks 40V 21′, the Litheli is lighter and easier to handle but sacrifices deck width and traction on slopes. Against the MightyMow 21′, it’s far more portable but can’t match runtime or cutting breadth. This is a standout pick for small yards, townhouse lawns, and quick weekly touch-ups, offering better portability than Greenworks 40V while keeping features simpler than the 60V class.
- Ultra-light
- Variable pace
- Tight turning
- Easy start
- Compact deck
- Shorter runtime
- Lower cut height

MightyMow 40V 21\” Brushless – Best Long Runtime
Built for endurance, the MightyMow 21′ marries a 3500 RPM brushless motor with dual 8.0Ah batteries, delivering up to 60 minutes self-propelled and 75 minutes push—excellent for larger yards. The 21-inch steel deck and boosted airflow collect clippings efficiently, and 3-in-1 cutting lets you mulch, bag, or side-discharge on the fly. Its self-propel speed (2.0–4.3 ft/s) helps on moderate slopes without wearing you out.
On mixed terrain, the mower keeps a steady pace and handles taller, late-spring growth better than smaller-deck competitors. The single-lever 6-position height range (1’–3′) suits most cool-season lawns, though the 3′ maximum can be limiting for those who prefer a taller summer cut. Weight is noticeable compared to compact models, but the drive assist offsets the heft for most users.
Versus the Greenworks 40V 21′, MightyMow delivers significantly longer runtime and stronger clipping collection, at the cost of a heavier feel. Compared to the Litheli 18′, it’s less portable but dramatically more capable for quarter- to half-acre lots. Best for homeowners wanting long runtimes and push-free mowing without jumping to a higher-voltage platform; it offers more staying power than Greenworks 40V while avoiding the complexity of the 60V tier.
- Long runtime
- Strong suction
- 21′ coverage
- Speed control

- Bulkier storage
Greenworks 60V 21\” Premium – Best High-Performance
Muscular yet refined, the Greenworks 60V 21′ brings high-voltage torque and rear-wheel-drive traction that makes thick spring growth and slopes feel manageable. With 4-in-1 versatility—mulch, bag, side discharge, and turbo leaf pickup—it’s a true all-season tool. LED headlights and whisper-quiet operation expand your mowing window and keep neighbors happy.
In real-world mowing, the 60V platform delivers punchy acceleration and smooth self-propel for consistent blade speed in heavy grass. The dual 4.0Ah batteries and rapid dual-port charger keep you cycling quickly, with around 45 minutes per set in typical conditions. It’s confident on uneven terrain, though users with very dense, tall grass may still need slower passes to maintain blade speed and finish quality.
Compared with the Greenworks 40V 21′, the 60V offers more power and better thick-grass performance, albeit with a bit more weight. Against the MightyMow 21′, it trades some raw runtime for stronger torque and a richer feature set (LEDs, turbo pickup). Ideal for homeowners who want premium performance and a 60V ecosystem for other tools; from a features-to-performance perspective, it outmuscles the 40V while feeling more refined than the MightyMow.
- High torque
- Rear-wheel traction
- 4-in-1 versatility
- LED headlights
- Rapid charging
- Heavier feel
- Shorter per-charge vs runtime-focused peers
Litheli 18\” Variable Speed – Best Small Yards
Agile and approachable, the Litheli 18′ shines for lightweight self-propel and electric start simplicity, making lawn care feel less like a chore. Its brushless motor keeps noise and maintenance down, while the 0.98’–2.95′ height range and variable pace give you control over finish quality. The 18-inch deck is ideal for narrow gates, tight beds, and townhome yards.
In day-to-day use, it’s at its best with short weekly cuts on small lots. The included 2x 20V 4.0Ah batteries provide about 30+ minutes; using bagging on damp grass can reduce that slightly. The compact bag capacity is decent for the class, but you’ll empty more often than with 21′ mowers, and the lower max cut height won’t suit those who prefer a tall summer cut.
Compared with the Greenworks 40V 21′, Litheli’s advantage is portability and easy handling; the trade-off is narrower path and shorter stamina. Stack it against the Greenworks 60V, and it’s simply the small-yard specialist: easier to store and carry, but not built for heavy growth or long sessions. Choose it if you want a best small yards pick with gentle ergonomics and minimal fuss.
- Super lightweight
- Easy maneuvering
- Variable self-propel
- Low maintenance
- Compact storage
- Shorter stamina
- Lower cut height
- Less slope grip
Greenworks 40V Compact Store – Best Easy Storage
Space-savvy and capable, the Greenworks 40V 21′ adds vertical storage that saves up to 70% floor space, perfect for tight garages. You get a brushless motor, rear-wheel-drive self-propel, and 3-in-1 cutting, all with instant electric start and no gas maintenance. The 7-position height adjust makes switching between spring scalp and summer lift effortless.
In use, it’s a confident performer on small-to-medium lawns with mild slopes. The 21-inch steel deck shortens mowing time versus smaller models, and the included 5.0Ah battery offers up to roughly 45 minutes in typical grass. It handles moderately thick turf, though dense or wet sections benefit from slower walking speed to maintain cut uniformity.
Compared with the Litheli 18′, this Greenworks is easier to live with for bigger yards due to the wider deck and better traction, though it’s not as featherweight. Against the MightyMow 21′, it’s more compact and easier to store but can’t match dual-battery endurance. For shoppers wanting best easy storage without sacrificing capability, it balances convenience and performance better than the small Litheli while staying simpler than the 60V model.

How to Choose a Lightweight Electric Start Self-Propelled Lawn Mower
Key Factors That Matter Most
- Weight and maneuverability: Look for models under ~65 lb with balanced weight and rear-wheel drive for traction on slopes. Lighter 18-inch decks (like Litheli 18″) are easier to handle in tight spaces; 21-inch steel decks (Greenworks, MightyMow) add durability but feel heavier.
- Battery system and runtime: Match battery voltage and Ah to lawn size. Small yards: 40V with 4.0–5.0Ah (30–45 minutes). Larger or thicker grass: dual-battery or higher-voltage systems (MightyMow 2x20V/8.0Ah, Greenworks 60V) for 45–60+ minutes. Check if charger is included.
- Cutting width and height range: A wider deck reduces passes on medium/large lawns (21″). Compact 18″ decks suit smaller yards and narrow gates. Seek 6–7 position single-lever height adjust, roughly 1″–3″ (or more) to adapt to seasons and grass types.
- Drive and speed control: Rear-wheel drive improves grip on hills. Variable self-propel speeds let you match walking pace (e.g., 1.3–2.9 MPH on Litheli; customizable pace on Greenworks 60V), reducing fatigue and improving cut consistency.
- Deck and build quality: Steel decks last longer and handle bumps; composite decks reduce weight and corrosion. Brushless motors across these picks deliver higher torque, quieter operation, and longer life with less maintenance.
Useful Features to Compare
- Start and maintenance: Instant electric start; no gas, oil, or pull cords. Brushless = fewer upkeep costs.
- 3-in-1 or 4-in-1 versatility: Mulch, bag, side discharge; premium models add turbo leaf pickup (Greenworks 60V).
- Storage footprint: Vertical storage options save up to ~70% space (Greenworks 40V Compact Store).
- Bag capacity: Larger bags (around 10+ gallons) reduce trips; helpful on 18–21″ decks.
- Lighting and visibility: LED headlights (Greenworks 60V) extend safe mowing windows.
- Ecosystem and warranty: Consider tool compatibility (Greenworks 60V works with 75+ tools) and longer warranties on tool/battery.
- Noise and emissions: Electric models are much quieter; some operate up to 3x quieter than gas.
Quick Match by Yard and Needs
- Small yards, tight spaces, ultra-light handling: Litheli 18″ Lightweight/Variable Speed.
- Best overall balance of power, features, and value: Greenworks 40V 21″ Self-Propelled.
- Long runtime for medium–large lawns: MightyMow 40V 21″ Brushless (2x20V, 8.0Ah).
- High performance, multi-mode, ecosystem value: Greenworks 60V 21″ Premium with LEDs.
- Minimal storage space: Greenworks 40V Compact Store with vertical storage.
Tip: Measure your lawn and typical mowing time, then select voltage/Ah to exceed that by ~20% to account for thick grass, hills, and seasonal growth.
