A rotary driver is coupled to the arm with a ball and socket joint so that the centrifugal fan oscillates in use. The fan assembly may be configured as an orchard sprayer to disburse pesticide into foliage and be mounted to, or towed by, an agricultural vehicle. In use the motion of the fan assists in opening up foliage for improved penetration of the pesticide therein.-- o CN CY) T I~ ITT CN 0#'FF'7 I~
