Ryobi released their first battery-powered riding mower, the RM480E, back in 2017. Using a lead-acid battery and featuring a 38-inch stamped steel deck it pioneered consumer battery-powered riding mowers. Next came the Ryobi 48-inch zero turn mower and, eventually, the 54-inch brushless ZT with a fabricated deck. Now, Ryobi released three new lithium-ion battery. The mower features cruise control as well which is useful for those long patches of land, and you can even charge your phone while mowing thanks to the built-in charger. As far as ergonomics go, the chair is placed pretty high and provides great cushioning and support, making the Ryobi ideal for protracted jobs.
