RYOBI 48V HP Brushless 54-inch Electric Zero-Turn Riding Mower — 115 Ah

The RYOBI 48 V HP Brushless 54-inch electric zero-turn is the flagship of RYOBI’s residential electric mower line, sized for property owners who want gas-zero-turn capability without any of the gas. With 115 Ah of onboard 48 V lithium battery storage (5.5 kWh) and four brushless motors driving the rear wheels and cutting deck independently, the mower can comfortably handle up to 4 acres in a single charge.

Power output rivals a 24 HP gas zero-turn, but with the instant torque, lower cabin noise and zero exhaust that only an electric drivetrain delivers. The dual lap-bar steering and dual independent drive motors produce true zero-radius pivoting, identical in feel to a gas equivalent.

The 54-inch fabricated steel deck has triple blades for a noticeably finer cut on dense grass and twelve cut-height positions between 1.5 and 4.5 inches. The premium operator station includes a 7-inch LCD instrument display, dual LED headlights, USB charging, cruise control, an adjustable high-back seat with armrests and dual cup holders.

Charge time on a standard 120 V outlet is approximately 9–10 hours; users with 240 V can shorten that significantly. Backed by a 5-year limited warranty on the mower (5 years on battery), making it one of the longest warranty terms in residential mowing.
