ABSTRACT:
Apparatus for treating the soil of a grass playing field that includes a piping system containing perforated pipe lines seated in a distribution bed beneath the soil of the playing field. A blower having a discharge port and a suction port is selectively connected to the duct networks to either pump air upwardly or draw air downwardly through the soil profile. A separator is connected in the air supply line of the system for removing water from the air stream moving between the blower and the duct network. The removed water is collected in a holding tank for recycling, or disposed of in an environmentally safe manner.
