ABSTRACT:
A sprayer assembly includes a frame that supports a tank for storing a liquid chemical. A pump moves the liquid chemical from the tank to one or more spray nozzles through a flexible hose supported by a boom arm that is attached to and extends from the frame. To allow for adjustment of the positioning of the spray nozzles, the boom arm has a curved end portion that defines a slot. A fastener can be passed through the slot and into a corresponding opening defined in the frame to attach the boom arm to the frame. As such, the boom arm can be fixed at any orientation between 90° (vertical position) and 0° (horizontal position) depending on the application.
