Method and apparatus for soil cultivation. |
摘要 |
<p>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 apparatus is such that, in use, there is created a water hammer effect which is sufficient to effect the flow of liquid out of the nozzles in the form of a square wave pulse. <IMAGE></p> |
