RYOBI RY48ZTR100 42-Inch 48V 100Ah Battery Electric Zero Turn Riding Mower

Product Description

The RYOBI RY48ZTR100 42-Inch Battery Electric Zero Turn Riding Mower is a fully electric residential zero-turn mower engineered for homeowners who want commercial-style maneuverability without the maintenance of a gasoline engine. Powered by a 48V 100Ah battery system, four high-performance brushless motors, and a durable 42-inch fabricated steel deck, this mower delivers quiet operation, instant torque, and the ability to mow up to 3 acres on a single charge. RYOBI has since discontinued this model, but it remains a popular electric zero-turn mower on the used market.

The mower operates on a 48-volt electrical system built from four 12V 100Ah sealed lead-acid batteries. Unlike gasoline-powered mowers, it requires no gasoline, engine oil, spark plugs, belts, air filters, or fuel-system maintenance, significantly reducing routine service requirements while producing zero exhaust emissions during operation.

Power is supplied through four brushless electric motors. Two dedicated motors drive the cutting blades while two independent wheel-drive motors provide the propulsion required for true zero-turn steering. The brushless design delivers immediate torque, smooth acceleration, and quieter operation than conventional gas-powered riding mowers.

Under typical residential mowing conditions, the integrated battery system can provide up to approximately 3 acres of mowing per charge. Actual runtime depends on grass thickness, cutting height, terrain, travel speed, battery condition, and weather conditions. Charging is completed using a standard 120V household outlet, allowing convenient overnight charging without special electrical installation.

The mower features a 42-inch heavy-duty steel cutting deck designed for durability and efficient airflow. Two electric blade motors power the cutting system directly, providing consistent blade speed and strong cutting performance across normal residential grass conditions. The fabricated steel construction improves durability compared to lighter residential stamped decks.

The deck provides 12 cutting-height positions with an adjustable range from 1.5 to 4.5 inches, allowing operators to adapt cutting height throughout the growing season while maintaining a healthy lawn.

The mower supports multiple grass-management methods including:

• Standard side discharge
• Mulching with compatible blades
• Grass collection using the optional 42-inch bagger attachment

Compatible accessories include the ACRM015 42-inch bagger, replacement blades, and protective mower covers. These accessories are sold separately unless specifically included by the retailer.

Zero-turn maneuverability is achieved through dual lap-bar steering controls instead of a steering wheel. Independent wheel control allows the mower to pivot around obstacles, reduce trimming work, and improve productivity on properties containing numerous trees, landscape beds, fences, and other obstacles.

Travel speeds reach up to 7 MPH, while cruise-style operation is achieved through the precision lap-bar controls. The electric drivetrain provides smooth acceleration without gear shifting or hydrostatic transmission maintenance.

Operator comfort is enhanced through:

• Adjustable 4-position seat
• Spacious foot platform
• Overmold lap bars
• Quiet electric operation
• Dual cup holders
• Enclosed storage compartments
• USB charging port
• LED headlights

These features help improve comfort during extended mowing sessions while providing convenient storage for personal items and mobile devices.

Routine ownership is simplified because there are no engine oil changes, carburetor servicing, spark-plug replacements, fuel stabilizers, or air-filter maintenance. Regular maintenance primarily consists of blade inspection, deck cleaning, tire-pressure checks, battery care, and periodic inspection of electrical components.

The mower carries a 3-year limited mower warranty with a 1-year battery warranty according to RYOBI’s published specifications.
