Best Cordless Electric Lawn Mowers: EGO vs Greenworks vs Ryobi

Cordless electric mowers have genuinely closed the performance gap with gas mowers over the past few years, and the three brands that dominate current buying guides — EGO Power+, Greenworks, and Ryobi — each target a slightly different buyer rather than directly competing on the same spec sheet. Here’s how the real current models compare.

Battery platform matters more than the mower itself

If you already own cordless tools (trimmers, blowers, chainsaws) from one of these brands, staying within that same battery platform saves real money since batteries and chargers are the most expensive components and are interchangeable across that brand’s tool lineup. That’s worth weighing alongside the mower’s specs themselves.

1. EGO Power+ LM2135SP

Repeatedly named “Best Overall” across 2025-2026 buying guides, EGO’s 56V ARC Lithium platform delivers strong torque (reviewers cite 6-8.3 ft-lbs depending on model) and long runtimes of 60-90 minutes, backed by the widest cordless tool ecosystem among the three brands.

Pros: strongest overall performance and runtime, widest battery-compatible tool ecosystem, self-propelled models available.
Cons: priced above Greenworks and Ryobi for comparable specs.

2. Greenworks 40V G-MAX Cordless Mower

Named “Best Value Electric Lawn Mower” by multiple reviewers, Greenworks’ 40V platform is the go-to for small-to-medium yards on a budget. Real-world user reports in forums note long product lifespans (some citing 9+ years) despite the lower price point compared to EGO.

Pros: best value for the performance, long reported product lifespan, good fit for small-to-medium yards.
Cons: less torque and runtime than EGO’s premium 56V platform.

3. Ryobi 40V Cordless Mower

Recommended mainly for budget buyers or anyone already invested in Ryobi’s 40V battery ecosystem from other tools. Forbes specifically named a Ryobi 11-amp model best for small lawns, making it a sensible pick if your yard is on the smaller side and you want to share batteries across your existing Ryobi tools.

Pros: most affordable of the three, shares batteries with existing Ryobi tool owners, good for small lawns.
Cons: least powerful of the three for larger or thicker lawns.

4. Kobalt 80V Max Cordless Mower

Kobalt’s 80V platform (sold through Lowe’s) is positioned as a higher-voltage alternative to the 40V class shared by Greenworks and Ryobi, which on paper gives it more headroom for thicker grass and larger yards without stepping up to EGO’s price point. It’s less common in independent buying-guide roundups than the other three brands, so there’s a smaller base of long-term owner reports to draw on, but it’s a genuinely sold, actively supported battery-mower platform worth cross-shopping if you’re already near a Lowe’s for other tool purchases.

Pros: higher voltage platform than the common 40V class, competitive pricing against EGO’s premium tier, widely available at Lowe’s.
Cons: smaller cordless tool ecosystem and fewer long-term reliability reports than the three more established brands above.

What to check before you buy

Decide on a battery ecosystem before comparing specific mower models — if you already own a trimmer, blower, or chainsaw on one of these platforms, the cost of a compatible battery-only mower (sold without a battery/charger, using one you already own) is usually meaningfully cheaper than buying a brand-new platform from scratch. Runtime claims are typically measured under light-duty test conditions, so expect real-world runtime on thick or tall grass to run shorter than the advertised figure — if your lawn is larger than about a third of an acre, consider either a second battery or a model explicitly rated for bigger yards. Self-propelled versions cost more but are worth it on sloped yards or if pushing a mower is a genuine physical strain; push-only models are lighter and cheaper but require more effort on hills.

Frequently asked questions

How long do cordless mower batteries typically last before needing replacement?
Lithium-ion mower batteries commonly hold meaningful capacity for several years of seasonal use before noticeably degrading, though exact lifespan depends on charge cycles, storage temperature, and how often the battery is run down to empty versus partially recharged.

Is a cordless mower powerful enough for thick or overgrown grass?
Modern 40V-and-up platforms handle typical residential grass, including moderately overgrown lawns, reasonably well, though very thick, tall, or wet grass is where gas mowers and higher-voltage cordless platforms like EGO’s 56V or Kobalt’s 80V still have a torque advantage over base 40V models.

Can I mix batteries between brands, like using a Ryobi battery in an EGO mower?
No — each brand’s battery platform uses a proprietary connector and voltage/communication protocol, so batteries are not cross-compatible between EGO, Greenworks, Ryobi, or Kobalt. Pick one ecosystem and stay within it for future tool purchases if battery-sharing savings matter to you.

Do cordless mowers need any routine maintenance beyond charging?
Yes — blade sharpening or replacement, cleaning grass buildup from the underside of the deck, and periodic battery contact cleaning are still part of ownership, though cordless models skip gas-engine maintenance entirely (no oil changes, spark plugs, or carburetor issues), which is one of the category’s real long-term advantages.

For most yards, EGO Power+ delivers the strongest overall performance and is the pick most reviewers default to when budget isn’t the limiting factor. If value matters more and your yard is small to medium, Greenworks’ 40V platform is a well-reviewed, long-lasting alternative at a lower price. If you’re already using Ryobi 40V batteries for other yard tools or have a genuinely small lawn, Ryobi’s mower lets you share that battery investment without buying into a new ecosystem, and Kobalt’s 80V platform is worth cross-shopping if you want more power than standard 40V without paying EGO’s premium price.
