Abstract
A turf sprayer has a truss shaped center boom and a pair of pivotal truss shaped wing booms within which spaced spray nozzles are supported. A drift shroud system comprises three integral and one-piece drift shrouds comprising a center shroud for the center boom and a pair of side shrouds for the wing booms. Each shroud is attached to an underside of the corresponding boom in a manner such that the shrouds project below the booms and not substantially above the booms to leave the truss-shapes of the booms open and unobscured to provide access to the spray nozzles within the booms. The shrouds each have openings in a top wall thereof for receiving the spray exiting from the nozzles with the spray passing downwardly between spaced front and rear walls of the shrouds.
