This is a new machine called the Air2g2. Basically this is fracking a green. This machine pushes tines into the green surface to a depth of 9 inches. It then sends a bust of air into the subsoil. This relieves compaction deep underground. It does all of this with only leaving a small hole, no clean up and no disruption of play. We will be working this practice into our aerification rotation.
