Claim:
1. An agricultural implement comprising: a central tool bar supporting central ground engaging tools and central fluid dispersal components; a first wing tool bar supporting first wing ground engaging tools and first wing fluid dispersal components, the first wing tool bar being pivotally coupled to the central tool bar at a first end; a second wing tool bar supporting second wing ground engaging tools and second wing fluid dispersal components, the second wing tool bar being pivotally coupled to the central tool bar at a second end, wherein the central, the first wing, and the second wing tool bars extend perpendicularly to a direction of travel; a central fluid conduit coupled to the central tool bar for conveying fluid to the central fluid dispersal components, the central fluid conduit having a first flexible end adjacent to the first end and a second flexible end at the second end; a first wing fluid conduit coupled to the first wing tool bar for conveying fluid to the first wing fluid dispersal components, the first wing fluid conduit having a first wing flexible end adjacent to the first end; a second wing fluid conduit coupled to the second wing tool bar for conveying fluid to the second wing fluid dispersal components, the second wing fluid conduit having a second wing flexible end adjacent to the second end; a first fluid joint coupled between the first flexible end and the first wing flexible end, wherein the first fluid joint is configured to provide a sealed connection between the first flexible end and the first wing flexible end during relative pivotal movement of the central and first wing tool bars in operation, enable uncoupling of the first flexible end and the first wing flexible end for servicing of the agricultural implement; and a second fluid joint coupled between the second flexible end and the second wing flexible end, wherein the second fluid joint is configured to provide a sealed connection between the second flexible end and the second wing flexible end during relative pivotal movement of the central and second wing tool bars in operation, and to enable uncoupling of the second flexible end and the second wing flexible end for servicing of the agricultural implement; wherein the first wing tool bar is configured to rotate the first wing ground engaging tools relative to the central ground engaging tools in response to pivotal movement of the first wing tool bar relative to the central tool bar, and the second wing tool bar is configured to rotate the second wing ground engaging tools relative to the central ground engaging tools in response to pivotal movement of the second wing tool bar relative to the central tool bar.
