Abstract
A turf sprayer comprises a transport vehicle that carries a laterally extending spray boom assembly. The spray boom assembly is both laterally displaceable and angularly displaceable relative to the transport vehicle. A controller uses a defined path represented by GPS coordinates to control the operation of various actuators to automatically maintain a reference point on the spray boom assembly on the desired path and to automatically maintain the spray boom assembly perpendicular to the desired path.
