Greenworks 40V Cordless Lawn Mower vs Ryobi 40V Brushless Lawn Mower: Full Comparison
I've spent years testing battery-powered lawn equipment, and the Greenworks vs Ryobi debate comes up constantly. Both brands have essentially redefined cordless mowing, but they've taken completely different paths to get there.
Let's start with the cutting deck. Ryobi sticks with the traditional 21-inch width you'd find on gas mowers, while Greenworks typically uses 20-inch decks. That extra inch means you're covering about 25% more ground with each pass on the Ryobi. For lawns over 1/4 acre, that difference actually matters—you'll finish noticeably faster.
But here's where Greenworks fights back: weight. Their mowers clock in around 37-40 pounds compared to Ryobi's hefty 48-58 pound range. That lighter design makes a real difference if you're maneuvering around flower beds, hauling the mower up basement stairs, or dealing with uneven ground. I genuinely appreciate this on smaller yards where you're constantly changing direction.
The battery situation is fascinating. Greenworks went with dual battery ports on many models, letting you run two 4.0Ah batteries simultaneously for up to 70 minutes of runtime. It's clever—you get extended runtime without buying expensive high-capacity batteries. Ryobi takes a different approach with single larger batteries paired with brushless motors that squeeze out about 20% more efficiency than brushed designs. Those brushless motors also last longer and need less maintenance over time.
From an ecosystem standpoint, Ryobi's ONE+ platform is massive—over 300 compatible tools including lawn equipment, power tools, cleaning devices, even portable electronics. That's serious versatility. Greenworks supports 60+ tools, which is still plenty but focuses more on outdoor equipment specifically.
Warranty coverage favors Greenworks with 5 years on tools versus Ryobi's 3 years. Battery warranties are comparable at 2-3 years for both. Pricing generally puts Greenworks $50-100 lower in similar categories, though kit configurations vary widely. Self-propelled options appear more consistently across Ryobi's lineup, which matters if you have slopes or larger properties.
For yards under 1/4 acre where maneuverability counts most, I'd lean toward Greenworks. The lighter weight and better warranty make sense here. But for bigger properties or if you're building out a full cordless tool collection, Ryobi's brushless efficiency, larger deck, and ONE+ compatibility justify the extra cost and weight.

Frequently Asked Questions
No, they're completely incompatible. Each brand uses its own proprietary battery design, so you can't mix and match. You're basically choosing an ecosystem, not just a mower.
Greenworks gives you up to 70 minutes if you use the dual battery setup, while Ryobi delivers 40-50 minutes with a single 5.0Ah battery. The difference is that Ryobi's brushless motors use power more efficiently, so you get more consistent cutting performance as the battery drains.
Ryobi handles overgrown grass better thanks to the extra torque from its brushless motors. Greenworks does fine in normal conditions, but you'll probably need to slow down or make extra passes if you let the grass get really thick or tall.
Ryobi has the edge here since it's sold exclusively through Home Depot, making it easy to get help or parts in person. Greenworks sells through multiple retailers but you might need to order specialized parts online. Their longer warranty helps offset that inconvenience though.
Ryobi's self-propelled models are better on slopes because of their variable speed drive and extra weight for traction. Greenworks is easier to push uphill since it's lighter, but it doesn't have the power-assisted control that really reduces fatigue on challenging terrain.
It depends on your priorities. Ryobi wins overall for most homeowners thanks to its larger 21-inch deck, brushless motor efficiency, and massive 300+ tool ecosystem, but Greenworks edges ahead if you have a smaller yard, value lightweight design, and prefer the superior 5-year warranty coverage.
Choose Ryobi if you want the best all-around performance, faster cutting with a bigger deck, and plan to build out a cordless tool collection. Pick Greenworks if you prioritize ease of handling, have a smaller lawn, and want maximum warranty protection and dual battery flexibility.
Ryobi features a 21-inch cutting deck and brushless motor for superior efficiency, plus compatibility with 300+ ONE+ tools, while Greenworks is lighter with dual battery ports and a 5-year warranty. Ryobi is built for larger properties and expanding tool collections, whereas Greenworks suits smaller yards and users who prioritize weight and warranty.
