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.

A spray apparatus for broadcasting solid particles, such as seeds or fertilizer, comprising: an upright storage hopper; particle discharge means at the lower end of the hopper for dispensing an even flow of particles from within the hopper; a radial vaned broadcast disk mounted beneath said particle discharge means for rotation about a central upright disk axis; a blower; a duct having one end operably connected to the blower for receiving a stream of pressurized air therefrom, said duct extending from said one end to a discharge nozzle at its remaining end; said duct being bifurcated with a first branch thereof forming a main airstream; and pneumatic drive means operably connected to said disk, comprising: a second branch of the duct leading to the disk for directing forced air against the disk vanes for rotating the disk about its axis to move particles which fall onto the disk from within the hopper; a manifold openly communicating with both branches of the duct for receiving particles from the disk and pressurized air from the blower and for mixing the air and particles to form the spray.
