Abstract: A watering spray system offering a method for softening soil in preparation for compacting the soil with a vibrating compactor attached to the end of an articulated arm of a backhoe, or the like equipment. The system includes a water spray head secured to the end of the articulated arm of the backhoe in full view of the backhoe operator to apply water for moisturizing back fill soil for compacting, a shut-off valve for controlling the water applied, a flexible water supply line starting at the water supply tank, running under the backhoe cab, and along the articulated main boom and arm, ending at the spray head. A welded frame assembly positioned at the rear of the backhoe, for suspending the flexible water supply hose above the backhoe motor for viewing by backhoe operator to determine tension on the hose, preventing over-stretching and possible damage to the conduit during operation. The source of water may vary to maintain sufficient pressure at the spray head.
