Abstract
A rotational joint is provided for an agricultural machine having hinged frame sections, each frame section carrying one or more plumbing lines for moving a carrier fluid. The rotational joint includes first and second joint parts. Each joint part has a coupler defining a flow passage leading to an interface opening. The joints parts are coupled to allow for relative rotation about a rotation axis passing through the interface openings. In at least one angular orientation of the joint parts, the flow passages of the couplers are in fluid communication.
