Ryobi now has a electric riding mower and a electric zero turn mower.Both are lead acid battery powered. Would like to see Ego do one with lithium batteries. I would sell my gas zero turn for an Ego zero turn.
I too would like to see EGO make a riding mower preferably a zero turn. Using their 56v batteries would be interesting since they make a generator that uses the 56v batteries and charges them on the same unit. It's could be possible and sooner than you think.
