A spray bar assembly in a material working system of a ground-engaging machine, such as a rotary mixer, includes a spray bar coupled with an elongate carrier by way of a hinge connector. The elongate carrier is supported between guides mounted upon a housing of a rotor in the material working system, to guide the spray bar assembly for linear movement relative to a frame of the ground-engaging machine. The elongate carrier has openings that register with spray ports in a housing of the system, and the spray bar is tiltable to position spray nozzles within the openings and spray ports or withdraw the spray nozzles from the openings and spray ports.
