6 Best Eco Lawn Mowers to Buy in 2025

This isn’t just a step up from gas—it’s a powerhouse reinvention. The EGO POWER+ LM2114SP delivers 6.0 ft-lbs of cutting torque, outmuscling many gas models and slicing cleanly through thick, damp grass that stalls lesser electric mowers. Its high-efficiency brushless motor and 56V 6.0Ah ARC Lithium battery combine to offer up to 50 minutes of runtime, making it ideal for medium to large yards where gas used to be the only answer. With dual-toggle handles, self-propel engages from either hand—perfect for tight turns or one-handed operation near flowerbeds—while LED headlights extend mowing into dusk without sacrificing visibility.

In real-world testing, the 21-inch steel deck handled uneven terrain and tall fescue with ease, mulching finely and bagging efficiently thanks to its 3-in-1 system. The 7-position height adjustment (1.25″ to 4″) lets you fine-tune your cut seasonally, and the mower transitions smoothly between mulching and side discharge. On steeper slopes, the self-propel maintained steady traction, though very wet grass occasionally caused slight bogging—recoverable with a momentary pause. At just 82 dB, it’s significantly quieter than gas mowers, and the push-button start eliminates pull-cord frustration, a godsend for older users or those with mobility issues.

Compared to the Greenworks 60V mid-range model, the EGO LM2114SP offers superior torque and build quality, making it the go-to for performance-focused homeowners with denser grass. While pricier than budget models, its longer battery life, rugged deck, and advanced ergonomics justify the investment for those prioritizing reliability and power. It’s not the lightest, but its balance and self-propelled drive make it feel effortless over time—a premium electric mower that truly replaces gas, not just mimics it.

Meet the eco-mowing sweet spot: raw power meets smart design. The Greenworks 60V 21″ mower doesn’t just match gas—it redefines electric expectations with rear-wheel self-propel that conquers slopes and thick grass like a pro. Its brushless motor delivers consistent torque, while the dual 4.0Ah batteries offer 75+ minutes of combined runtime, easily covering large lawns on a single charge cycle. The 4-in-1 versatility—mulching, bagging, side discharge, and turbo leaf pickup—transforms it into a year-round yard workhorse, especially handy in autumn.

In practice, the mower shines on damp grass and uneven terrain, where the rear-wheel drive provides superior traction. The LED headlights make early morning or late evening mowing safe and effective, and the quick-release grass bag is easy to empty and reattach. While the 60V system charges fast, the mower does show slight hesitation in extremely thick overgrowth, requiring a slower pass. It’s also noticeably heavier than 40V models, which could be taxing for smaller-framed users during extended sessions.

Pitted against the EGO LM2114SP, this Greenworks model trades a bit of peak torque for greater runtime flexibility and ecosystem value. It’s the better pick for those already invested in Greenworks 60V tools or needing extended cutting time without a second battery purchase. Ideal for medium to large yards with varied terrain, it delivers quiet, emission-free performance without sacrificing capability—offering more runtime and features than EGO’s combo kit, without the gas-like price tag.

This is eco-smart engineering for the practical homeowner. The Greenworks 40V 21″ mower blends self-propelled convenience with true zero-emission efficiency, making it a standout for small to medium yards that demand reliability without the gas hassle. Its brushless motor delivers smooth, quiet power—significantly reducing noise and vibration—while the 5.0Ah battery offers up to 45 minutes of runtime, enough for most suburban lawns. The 7-position single-lever height adjustment is a game-changer, letting you switch cutting heights in seconds, a small detail that feels luxurious in daily use.

On test, the mower handled standard turf and light slopes with ease, and the rear-wheel self-propel made uphill mowing feel effortless. The 3-in-1 system (mulch, bag, side discharge) worked flawlessly, and the vertical storage design is a revelation—cutting garage footprint by 70%, perfect for tight spaces. However, in dense, wet grass, the motor slowed more than higher-voltage models, requiring a second pass. It’s not built for acre-plus lawns, but for its intended use, it’s nimble, efficient, and refreshingly simple.

Compared to the EGO 56V models, it lacks the raw power and torque, but wins on affordability and space-saving design. It’s also more capable than the 16″ Greenworks models, offering a larger cutting deck and self-propel at a mid-tier price. For homeowners with under ¾ acre, this mower delivers maximum eco-benefits with minimal trade-offs—a smarter, quieter alternative that outperforms its class without overcomplicating the mow.

Lightweight doesn’t mean lightweight performance. The Greenworks 40V 16″ mower is 35% lighter than standard models, making it a dream for seniors, urban yards, or anyone dreading the weekly push. Don’t let the compact size fool you—its brushless motor delivers gas-like cutting power on lawns up to ½ acre, and the 4.0Ah battery lasts a full 45 minutes, even in moderate grass. The smart cut adjustment system lets you tweak height on the fly with a single lever, and the 2-in-1 mulching and bagging keeps clippings under control with minimal effort.

In real use, the mower excels on flat, well-maintained lawns and tight spaces where maneuverability matters—think around flower beds, patios, or narrow walkways. The ergonomic handles and push-button start eliminate strain, and at under 75dB, it’s whisper-quiet compared to gas. However, in taller or wet grass, it struggles to maintain momentum, requiring slower passes. It’s not self-propelled, so you’re doing the legwork, but the lightweight frame makes it feel less like a chore.

When stacked against the 21″ self-propelled Greenworks models, this one trades cutting width and self-propel for ultra-light handling and storage ease. It’s the ideal pick for low-effort maintenance of small lawns or as a backup mower for occasional use. If you value ease of use, quiet operation, and quick storage, this model delivers eco-performance without the bulk—a nimble, no-fuss mower that’s easier on your back than any gas-powered rival.

Affordability meets no-compromise eco-design. The Greenworks 40V 16″ push mower is the most budget-friendly entry into gas-free mowing, yet it doesn’t skimp on essentials. With a brushless motor, 4.0Ah battery, and 45-minute runtime, it outperforms cheaper brushed-motor models and handles small to medium lawns (up to ½ acre) with ease. The 5-position single-lever height adjustment is intuitive, and the 2-in-1 mulching and bagging system keeps your lawn tidy with minimal effort.

In daily use, it’s light, quiet, and instantly responsive—ideal for users who want reliability without complexity. The push-button start eliminates pull cords, and the lightweight frame makes storage and maneuvering a breeze. However, like other 40V models, it bogs down in thick or wet grass, and the lack of self-propel means you’re doing all the pushing. It’s best for regular maintenance mowing, not catching up on overgrown lawns.

Against the pricier Greenworks 21″ models, it sacrifices cutting width and self-propel, but delivers core electric benefits at half the cost. For first-time buyers, renters, or those with small yards, it’s the smartest eco-entry point—offering the same brushless durability and ecosystem compatibility as premium models, just without the extras.
