A folding toolbar for an agricultural implement. A unitary flex hinge structure connects adjacent sections of the toolbar and provides a dual pivoting function. The flex hinge pivots about a first pin connected to a first section and is in pivotal connection about a second pin connected to a second section, the first and second pins defining axes that are orthogonal to each other. The unitary flex hinge further includes a lug plate that defines a mid plane along which a force may be applied. The mid plane and the axis of the first pin may be coplanar to reduce bending moments about the flex hinge relative to conventional arrangements where the axis of a hinge pin is offset relative to the plane in which the force is applied. The first pin may be mounted to a hinge mount that is mounted to lug plate for a compact design.
