The local golf courses use a core aerating machine attached to a tractor in which the plugs are pulled straight up and down and it does a great job of pulling plugs and leaving the turf with minimal damage. All of the rental models I've seen are a drum type and they have a tendency to rip the grass or make sloppy holes. Does anyone know if there are core aerators that pull vertically available to homeowners? The greens keeper did not know of any.
