a light - weight turf conditioning machine provides programmable subterranean soil processing . the machine includes a set of electronically controlled air guns that are mounted on a frame a given distance above the ground . each air gun disperses a high pressure stream of fluid into the ground in a vertically aligned cylindrical shape drilling holes into a golf green . the holes are drilled using a hydrated polymer that absorbs and releases moisture in a controlled fashion fostering plant growth . a programmable controls circuit controls the rate , pattern and depth in which holes are drilled into a golf green . a portable storage tank is fluidly joined by a hose to the air guns . the hose allows the storage tank to spaced from the machine as the air guns are carried over the golf green .
