EGO vs Greenworks vs Ryobi: Which Cordless Mower Platform Wins in 2026?

Updated September 2026 · 12 min read

Batteries are the new engine. Pick the wrong cordless platform and you'll spend the next decade rebuying the wrong batteries; pick the right one and every future tool — blower, trimmer, chainsaw, even a snow blower — shares the same packs. This guide compares the three cordless outdoor-power platforms that matter in 2026 on the things that actually matter: runtime, cut quality, ecosystem depth, and what it costs to live with each for five years.

TL;DR — Quick Picks:

• Best Overall Platform: EGO POWER+ ($499–$649 for the mower) — best cut quality in cordless, deepest tool ecosystem, industry-leading 56V arc-lithium packs. → check price
• Best Value: Greenworks 40V/60V ($299–$449) — 80% of EGO's performance at 70% of the price, massive tool ecosystem. → check price
• Best Budget (small yards): Ryobi 40V ($329–$399) — Home Depot exclusivity means easy warranty walks, and the 40V line covers every basic tool. → check price
• Best for Big Yards: EGO with two 7.5Ah packs — genuinely replaces a 30" gas deck for properties up to ~2 acres.

The Battery Platform Decision (Why It Matters More Than the Mower)

A gas mower is a single decision. A cordless mower is a marriage. The mower itself is the cheap part — the batteries are where platforms win or lose you. EGO's 56V packs run from 2.5Ah ($129) to 12Ah ($549); buy once, use everywhere. Greenworks' 40V and 80V lines cover the widest price spread. Ryobi's 40V "ONE+" ecosystem spans 40+ tools at the lowest per-tool prices — but its packs are the least durable of the three under sustained load.

Runtime: What the Spec Sheets Don't Say

Manufacturers quote runtime on fresh packs cutting light, dry grass. Real-world numbers are 30–50% lower. Here's what our testing and owner reports converge on for a typical 0.5-acre suburban lawn:

• EGO 56V 7.5Ah: 45–55 minutes, cuts wet fescue without bogging. The best cut quality of the three — TORO-like deck airflow.
• Greenworks 40V 5Ah: 35–45 minutes on the included pack; add a second for anything over 0.75 acre. → check price
• Ryobi 40V 6Ah: 35–45 minutes, bogs in thick St. Augustine, but recovers better than older packs. → check price

Cut Quality Ranked

1. EGO — best airflow and mulching in the cordless class; bagging performance is gas-tier.
2. Greenworks 80V — close second; the 80V deck handles thick St. Augustine well. → check price
3. Ryobi 40V HP — good in light growth, struggles in wet/thick conditions. → check price
4. Greenworks 40V — fine for weekly cuts on thin lawns. → check price

5-Year Cost of Ownership

Batteries degrade — expect 60–70% capacity at year 4–5 regardless of brand, and budget one replacement pack in a 5-year window (~$180–250). No gas, no oil, no spark plugs, no winterization: cordless maintenance is ~$0/year beyond blades and sharpening. Over 5 years a cordless setup typically runs $700–1,100 total vs $900–1,400 for a comparable gas walk-behind once you count fuel, oil, plugs, and carb cleaner. The gap narrows every year as battery prices fall.

Which Platform for Which Yard

• Under 0.5 acre, suburban: Ryobi 40V or Greenworks 40V — spend the savings on a second battery, not a bigger deck. → check price
• 0.5–1.5 acres: EGO 56V with 7.5Ah packs. Cut quality and runtime lead the class.
• 1.5–3 acres, open: Greenworks 80V or EGO dual-battery setup. Or just buy gas. → check price
• Who should still buy gas: anyone mowing 2+ acres of thick, wet, or hilly grass weekly. Cordless is close but not there yet in 2026.

Verdict

EGO is the platform to marry in 2026 if cut quality and runtime are priorities. Greenworks 40V wins on value-per-dollar for under-1-acre yards. Ryobi is the budget ecosystem with the widest tool selection and the easiest warranty (Home Depot). One exception: if you already own a platform, stay in it — switching brands to save $50 on a mower means rebuying $500 in batteries.
