We signed up for a service last year that uses only electrified/battery powered devices (as opposed to IC engines), mainly just for the green aspect of it. But I'll be danged if they're not also like a third the volume of the gas ones! The first time they showed up, my wife saw a dude walking back and forth behind a push mower (looking out through the closed window of her office), and she thought he literally didn't even have it on yet. That's how much quieter they are. I think that's a damn good balance. Dudes with reel mowers and rakes are gonna be out there for like two hours every time they come; very not interested.
