ABSTRACT:
Devices and methods for softening the infill layer of artificial turf. Multiple prongs extend from a rake or a rotating drum or wheel that is pushed or pulled across the artificial turf. In one embodiment, the prongs eject pressurized gas or liquid into the base of the infill. In another embodiment, the prongs vibrate within the base of the infill. Ideally, both methods are employed. The forced gas and/and or fluid, and the vibration, serve to loosen the rubber and sand particulate that make up the infill and thereby soften the artificial field.
