In-depth review
The RYOBI 40V Brushless Lawn Mower delivers gas-comparable cutting power without the noise, fumes, or maintenance hassles that come with traditional mowers. Built around a durable brushless motor, this cordless mower generates strong torque to tackle thick grass and overgrown patches with ease, while running significantly quieter than gas-powered alternatives. The 40V lithium-ion battery system provides ample runtime to handle mid-to-large residential lawns on a single charge, and because there's no gas, oil, or spark plugs involved, starting the mower is as simple as pushing a button—no more pulling a cord repeatedly or dealing with stalled engines.
Designed with homeowner convenience in mind, this RYOBI mower features multiple height adjustment settings, allowing users to customize cutting length based on grass type and seasonal needs. The deck size is optimized for efficient coverage, reducing the number of passes needed to complete mowing tasks, while the 3-in-1 functionality supports mulching, bagging, and side discharge depending on your yard care preference. The lightweight, brushless design also means less vibration and reduced fatigue during operation, making it easier to maneuver around flower beds, trees, and other landscaping features without straining your arms or back.
Beyond performance, this RYOBI mower emphasizes eco-friendly, low-maintenance lawn care. Since it runs entirely on battery power, there are no emissions, no gas station trips, and no annual tune-ups required—just charge the battery, mow, and store it away when finished. Many models in this lineup are also compatible with RYOBI's broader 40V tool ecosystem, meaning the battery can potentially be shared across other yard equipment like trimmers or blowers, adding long-term value. Whether you're maintaining a small suburban yard or a larger property, this brushless mower combines power, quiet operation, and sustainability into a reliable outdoor tool built for consistent, hassle-free lawn care season after season.

What owners say
Switched from a gas mower and couldn't be happier. Starts instantly, no fumes, and cuts my half-acre lawn on a single charge with battery to spare.
Mower itself is fantastic - quiet, powerful cut, easy to maneuver. I do need a second battery for my larger yard, which adds to the cost.
Was skeptical about battery power matching gas mowers, but this thing chews through thick grass without bogging down. Self-propel feature is a nice bonus on hot days.
Works great for my quarter-acre lot. Lightweight enough for me to maneuver easily and store in the garage without hassle.
