  • Patent number: 6152651
    Abstract: An apparatus for raising a component of an underground sprinkler including a hydraulic actuator in fluid communication with a pressurized fluid source normally associated with an underground sprinkler system, and operably connected to a base of the underground sprinkler. The hydraulic pressure provided by the pressurized fluid source is used to drive the hydraulic actuator and adjust the level of the base of the underground sprinkler within the ground. In a particular embodiment, the hydraulic actuator includes a hydraulic cylinder and a wand in fluid communication with the pressurized water source. The wand is inserted into the ground around the sprinkler base, thus fluidizing the ground and allowing the operator to more easily move the sprinkler base.
