A hinge assembly with two pivot axes is provided for a folding frame. One pivot axis, a working pivot axis, allows the outer wing frame to rotate while in operation to follow the ground contours by rotating relative to the adjacent frame section without creating any interference between adjacent tools mounted to the frame sections. The second pivot axis is a folding pivot axis above the frame and about which the outer wing frame rotates to fold the outer wing into the transport position. This hinge assembly when used on a five section implement frame allows the outer wing frame to both follow the ground contour and to fold into an acceptable transport position.
