  • Patent number: 6776355
    Abstract: A sprayer switching control system includes toggle switch structure incorporated into the main control handle of the sprayer and toggling spray sections sequentially so that each section changes condition in turn as the switch structure is operated. A reset switch located adjacent the toggle switch structure is operable to reset all the sections to a preselected operating condition. A first switch toggles section condition sequentially in a first direction along the sprayer boom, while operating a second switch reverses the direction. Such toggle operation is simple and easy to learn, and can be implemented without removing the hand from the control handle. To accommodate special skip patterns and shut off unused boom sections, individual section control switches mounted away from the handle to avoid handle clutter permit selective disabling any one or more of the spray sections.
