The first real mow of the year usually lands in early May, when the low ground near Brooklyn Square greens up ahead of the hills and the city seems to exhale. Mr. Mow It All starts the season there and keeps it going into October, cutting on a weekly turn, trimming close where the mower cannot reach, running the edge along drive and sidewalk lines, and clearing the clippings so a yard looks done rather than merely mown. Cleanups open and close the calendar, with winter's leftovers out in spring and the leaf load off before the ground freezes. There is a plain pleasure in a straight mow line on a Jamestown side street, and it is worth the extra minute to get one.
