Abstract
A multi-row agricultural soil treatment implement includes a semi-trailed carriage and a rearward folding toolbar. The toolbar is suspended from the semi-trailed carriage through parallel links and includes a center section, flex hinges, main wings, main wing latches, and outer flip wings operatively connected to hydraulic cylinders to move them between transport and field position. The main wings fold rearward relative to the center section and are supported by a transport rack but they retain the ability to pivot up or down as needed for ground contour following capability or row end turning.
