Zusammenfassung:	An apparatus and method is disclosed for cultivating soil and turf by utilization of pressurized liquid injected into the soil and turf. A roller assembly (33) is provided for applying mechanical pressure to the turf after cultivation Further, a means for setting a first speed in a transport mode and a second speed in a cultivating mode is provided. The apparatus is designed to be bidirectional to allow the apparatus to be used in both a forward and reverse direction. The flow of the pressurized liquid is controlled to be at intervals of from about 0.010 to 0.065 seconds and at pressures from about 2,300 psi to about 5,500 psi through nozzles having diameters of from about 0.033 to about 0.090 inches. The apparatus (10) utilizes a water hammer effect to effect the flow of pressurized liquid out of the nozzles 55 and has found a relationship in the pressure and pounds per square inch of the cr? sectional area of the bore of the manifold to the accumulated area of the output ports of the nozzles.
