November on the Eastchester line is the hinge of the year — leaves still falling while the first hard frost is already whitening shaded lawns before eight. Harter Landscaping of Eastchester carries the whole swing: mowing, trimming and seasonal cleanups on one side of it, plowing, shoveling and de-icing on the other. Between Yonkers and the villages east of it the ground changes quickly, from tight city blocks to deeper yards under old oaks, and the work changes with it property by property. When the switch happens overnight, as it does here, the trucks are already loaded.
