EGO Power+ zero turn (ZTR) and push mowers are battery ... Anyone who's been woken at the crack of dawn can tell you that gas-powered riding mowers are noisy, noxious machines.
My yard has a sizeable 1.5-acre mowable area. While we've had a traditional riding mower that gets the job done, it's not zero-turn, it's not quiet, and it requires lots of seasonal maintenance.
