The Gifford Park streets are all porches and tall windows, and the lawns in front of them are narrow, parkway strips and side yards a mower has to be coaxed into. L.O. Mowing works those tight spaces early, while the shade is still long across the sidewalks and before heat comes up off the pavement. Every pass runs straight, every trim line follows the walk, and what gets cut goes back onto the grass instead of into the gutter. Old houses deserve a lawn that matches the trim work on them. That is the whole idea.
