Abstract: A hydraulic gate closure device includes a vault that is buried underground. A junction box is positioned in the vault and a closer is positioned in the junction box. The closer has a knob which is rotatably integrated into the closer. The knob is biased to rotate in a first direction and the knob is rotatable in a second direction. A pole is coupled to and extends upwardly from the junction box and a stanchion is vertically oriented on the ground. A gate is coupled to the knob of the closer and the gate is located between the stanchion and the pole. The gate is positioned in a closed position when the knob is biased to rotate in the first direction and the gate is urgeable into an open position.
