Mobile unit for treating soil
DCFirst Claim
1. Apparatus for treating the soil of a sportsfield or grass site that includesa duct network buried beneath the soil of a site in a gravel bed, ducts in said network having perforations therein that are in fluid flow communication with said gravel bed,a mobile unit that includes a blower means for supplying air to the duct network at a pressure and volume such that the air is distributed uniformly throughout the bed and is forced upwardly through the soil into the ambient surrounding the site,means for coupling and decoupling the blower to the duct network, anda flow reversing means for reversing the flow of air through said duct network that includes a four-way valve mounted upon the mobile unit for selectively connecting the duct network to either a discharge port on said blower or a suction port on said blower whereby air can be either pushed upwardly through the soil or drawn downwardly through the soil.

8. Apparatus for treating the soil of a grass sportsfield that includes
a duct network situated beneath the soil of a grass sportsfield in a gravel bed, ducts in said network having perforations therein that are in fluid flow communication with said gravel bed, a drain line coupled to said duct network for draining moisture from the duct network, a mobile unit that includes a blower means having a discharge port for supplying air to the duct network at a pressure and volume such that air is distributed uniformly throughout the bed and is forced upwardly through the soil into the ambient surrounding the grass sportsfield, means for coupling and decoupling the discharge port of the blower to the duct network, and valve means operable for selectively connecting and disconnecting the drain line to said duct network wherein said drain line can be isolated from said duct network when the blower is coupled to the duct network.
