Ridge Road carries you past the low white Odell House in Hartsdale, its lawn running flat and open to the trees. T&M Landscaping Inc. keeps ground like that across Greenburgh — mowing, trimming, edging the drives, mulching the beds, and hauling out the leaves when the town turns rust and gold. An open lawn shows everything: a wandering line, a missed strip, a ragged border. So the passes go down straight and overlapped, and the trimmer follows the mower everywhere it could not reach. When the blower finally goes quiet, the yard has that even, brushed look that lasts right up to the next cut.
