My current (non-riding) mower is made by Greenworks. I love it. They have
moved to lithium ion battery technology. They also have at least one commercial

I like this company because the CEO is not only a nice guy, but is a motivated
guy who wants all yard equipment to go electric. He has started from scratch
and works his tail off. I give him credit for a movement that is gaining steam
for commercial lawn companies to use electric yard equipment, and for cities to
spec them in contracting out services.
