Mobile unit for treating soil
DCFirst Claim
1. Apparatus for treating the soil of a grass sportsfield that includesa 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 an inlet port for creating a vacuum in the duct network such that air is drawn downwardly through the grass sportsfield,means for coupling and decoupling the inlet port of the blower to the duct network, andvalve means operable for selectively connecting and disconnecting the drain line to said duct network, said valve means including a first valve for coupling the duct network to the drain line and a second valve for coupling the blower to the duct network, wherein said drain line can be isolated from said duct network when the blower is coupled to the duct network.
