Air 2 g 2 machine working on the putting green. This machine penetrates the ground to 11 inches and the shatters the underlying hard pan using compressed air. The tines have a series of holes for the air to be released. This will create several fissures in the soil that will allow for better drainage and also supply the roots with some much needed oxygen. The beauty of this machine is there is very little disturbance to the surface. A single roll with the turf iron returns the surface to normal.
