Across America, a quiet revolution is unfolding—autonomous electric mowers are gliding silently across parks, ballfields, and backyards.

Landscapers love the mowers because they free up time for more skilled tasks. Homeowners love them because their lawns look pristine. And neighborhoods? Well, they finally get their peaceful, quiet Saturday mornings back.
