Ryobi has established itself as a leader in the transition from gas-powered lawn equipment to battery-operated alternatives. Since the introduction of their first-generation crosscut mower in 2021, the brand has focused on addressing user feedback to refine its 40V HP Brushless Self-Propelled line. The latest 21-inch Crosscut model represents a significant step forward, aiming to match the power of a 170cc gas engine while offering the convenience and quiet operation of a cordless platform. This review explores the features, performance, and long-term reliability of Ryobi’s flagship cordless mower.
Where to Buy & Pricing Info
Key Features and Design
Cutting Power and Motor
The heart of the mower is a brushless motor delivering 9.7 ft-lb of torque. This performance level is designed to compete with commercial-grade electric mowers and high-performance gas models. To manage different grass densities, Ryobi utilizes intelligent electronics that automatically activate a "Turbo" mode when an increased load is sensed on the blades. This ensures consistent blade speed through thick patches while conserving battery life during lighter tasks.
Dual Crosscut Blade System
A standout feature of the "LMO2" version is the dual stacked crosscut blade system. This design serves two primary purposes: it finely minces grass for superior mulching and generates significantly higher airflow for bagging and side discharge. The improved lift helps the mower gather more clippings into the two-bushel bag or distribute them more evenly through the side discharge outlet.
Build and Ergonomics
The mower features a molded poly deck rather than traditional steel. While the use of plastic is a point of debate regarding long-term durability, it offers the benefit of being rust-proof and lightweight, keeping the total weight at approximately 79.2 pounds. For user comfort, Ryobi includes an adjustable two-position handlebar and a centralized control center. This panel allows users to incrementally adjust drive speed, toggle LED headlights, and monitor battery life or blade status.
Performance and Cut Quality
In real-world testing, the mower provides a clean and confident cut. The single-point height adjustment lever makes it easy to choose from 10 positions ranging from 1 to 4 inches. While the mower handles most lawn types with ease, some users have noted that the suction power does not quite match that of a high-end gas mower, occasionally leaving a few "stragglers" in very tall or thin grass.
The transition between mulching and bagging has been simplified in the latest generation. Instead of a cumbersome mulch plug that frequently gets stuck, the new design uses a small, reliable dial to open and close the mulch plug door. This allows for a seamless change in mowing styles without needing to stop and manually insert or remove components.
Battery Life and Runtime
Dual Battery Management
The mower utilizes a dual battery bay where batteries operate in parallel. This configuration allows the mower to run on a single battery if necessary, but using two batteries simultaneously increases total runtime and keeps the batteries cooler under heavy loads.
Estimated vs. Actual Runtime
Runtime varies significantly based on grass type and outdoor temperature, but general estimates include:
- Two 6Ah batteries: Approximately 75 minutes.
- Two 8Ah batteries: Approximately 100 minutes.
- Two 12Ah batteries: Up to 150 minutes.
While Ryobi suggests these batteries can cover up to 3/4 of an acre, realistic expectations for thick or overgrown grass are closer to a 1/2 acre. For larger properties, users may need to keep spare batteries on hand or consider upgrading to Ryobi's 80V tractor line.
Pros
- Quiet Operation: The electric motor is significantly quieter than gas alternatives, making it ideal for neighborhoods with noise restrictions or early-morning mowing.
- Low Maintenance: Users can "ditch the gas habit" and avoid the hassles of carburetors, oil changes, and fuel stabilization.
- Thoughtful Controls: The advanced control panel and adjustable drive levers provide a customizable and user-friendly experience.
- Easy Storage: The machine is designed to fold in half, allowing for vertical storage that saves significant space in a garage or shed.
- Rust-Proof Deck: The poly deck eliminates concerns about the mowing housing rotting out over time.
Cons
- Lower Suction: Compared to gas models, the vacuum effect is slightly weaker, which can lead to missed blades of grass in certain conditions.
- Poly Deck Sensitivity: While durable against rust, the plastic housing can be flexible. Some users reported that bumping the mower into a tree while the blades are running can cause the blades to momentarily strike the side of the deck.
- Price Point: With a retail price of approximately $649 for the kit, the initial investment is higher than many entry-level gas mowers.
Target Audience
The Ryobi 40V Crosscut Mower is best suited for homeowners with suburban lots up to a half-acre in size. It is an excellent choice for those living in communities with strict noise ordinances or homeowners associations. Furthermore, it is ideal for users who prioritize ease of use and minimal maintenance over raw commercial power. If you already own other Ryobi 40V tools, the ability to swap batteries makes this mower an even more logical addition to your tool shed.
Final Verdict
The Ryobi 40V HP Brushless 21-inch Crosscut Mower is a sophisticated piece of lawn care technology that successfully addresses the main pain points of gas mowing. By combining a clever dual-blade system with intelligent power management, Ryobi has created a machine that is both powerful and pleasant to operate. While it may lack the extreme suction of a professional gas unit and carries a premium price tag, its convenience, quiet performance, and thoughtful design features make it one of the most attractive cordless options on the market today.
