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.
