"Introducing RYOBI's first lithium-ion battery powered zero turn riding mower, the RYOBI 80V HP 54"" Lithium Electric ZTR*. HP Technology and 80V batteries combine to deliver the power equivalent of a 42 horsepower gas engine*, while eliminating the hassle and maintenance of a gas mower. This rider cuts up to 4 acres per charge with the help of 5 brushless motors, (3) 80V 10Ah batteries, and (4) 40V 12Ah batteries, with a Super Charger that fully recharges in 5 hours so you're ready for your next job. The revolutionary iDrive system uses an intuitive one-handed joystick steering to maneuver around objects more easily than a traditional ZTR. The innovative LCD screen displays runtime, battery life, and cut/drive speed while in use, while the Riding Mower app allows you to monitor charge time and battery life remotely. This riding mower features the CROSS CUT multi blade system, providing superior cutting & mulching performance, while the 12-point height adjustment allows you to select the perfect cutting height between 1.5"" and 4.5"". The rubber side discharge chute makes it easy to maneuver around landscaping so users are not restricted by where they can cut. Designed with comfort and convenience in mind, this mower features premium seat suspension, 2 USB ports to charge phones, a storage compartment, and LED headlights. Lawn maintenance will never be the same thanks to the RYOBI 80V HP Brushless 54"" Lithium Electric Zero Turn Riding Mower."
