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.

Abstract: A valve actuator is provided which clamps to the axially extending assembly bolts of the valve or to ribs on the valve body simulating the bolts. The actuator has a support frame with ears which seat over a pair of the bolts or ribs and by means of stops formed by recesses in the ears seat the support frame on the bolts or ribs and threaded anchor members, when tightened, cause the ears to tightly clamp to the bolts or ribs, preventing either lateral or axial movement with respect to the valve body.
