A leveling system for use with a mobile stage vehicle, the mobile stage vehicle having a stage floor. The leveling system includes a hydraulic actuation system. A plurality of leveling devices are coupled to the mobile stage vehicle of the portable stage for the leveling thereof. A hydraulic control system is coupled to the hydraulic actuation system for the control of the hydraulic actuation system. The hydraulic control system has level sensor devices coupled to the mobile stage vehicle for detecting the inclination of the mobile stage vehicle and indicators means coupled to the level sensor devices for presenting a viewable indication of the level status of the mobile stage vehicle. A switch is coupled to the hydraulic actuation system for providing a command to the hydraulic actuation system whereby the leveling devices are actuated responsive to an out of level indication on the indicators to effect leveling of the stage floor of the mobile stage vehicle.
