Half the lawns under High Mountain sit on a pitch, and grass on a pitch is its own trade, because the mower has to be driven rather than merely pushed. GroundTechs takes those Preakness slopes as they come, cutting across the grade and keeping turf thick enough to hold soil through an October downpour. Trimming finishes the retaining walls and the awkward strips no wheel can reach, while edging gives a driveway a defined border that reads clean all the way from the bottom of the hill. Seasonal cleanups clear the leaf drift that collects against every wall on a hillside property. It is fussier work than flat ground, and it looks better for it.
