Abstract: A spray device is disclosed that is mountable to a truck for movement therewith along a roadway for the purpose of spraying seeds, fertilizer or other solids or liquids onto the roadside. The device includes pivotably interconnected frames that permit pivotal movement of the device about horizontal and vertical axes. The frames releasably mount a portable blower and spray discharge mechanism at their opposite longitudinal ends. A duct interconnects the blower and spray discharge. It provides air for driving a spray discharge mechanism to eject a spray outwardly at a selected trajectory along a roadside area. Various modifications are shown for adapting the structure to spray a liquid mist or for spraying seeds or fertilizer along a roadside area. The device makes use of a portable blower that can be mounted to the frame or removed therefrom without modification.
