Chatsworth lies along Route 24 in Livingston County farm country, where the sky takes most of the view and the town shows up first as a stand of shade trees you can see coming for miles. Diller Millworks LLC keeps lawns through the green part of the year there, mowing on a steady turn with the height set so the grass carries its color into the dry weeks. The trimmer follows the fence line and the foundation, the mower turns square at the corners, and the walks and drive come out clean at the end. Leaves are cleared off in fall so nothing sits wet on the turf all winter. In a town this open to the weather, a tended yard is a small and deliberate order.
