An agricultural implement is provided that has a variable placement hinge joint that allows adjacent implement sections to flex relative to each other and can be moved by an actuator to control spacing between adjacent work zones defined by the implement sections. This can be done by detecting relative angle changes between adjacent implement sections and moving the hinge joint to maintain a constant distance between the work zones so that row spacing is substantially constant across the entire implement, even between adjacent ground-engaging tools or other working units of different implement sections.
