Abstract: An agricultural implement having main and wing sections which are joined by a folding mechanism. The folding mechanism includes a first pivot connection for allowing generally horizontal pivoting movement of the wing section between a field working position and a folded position. In either position, the wing section remains in essentially the same plane as the main section. The folding mechanism further includes a second pivot connection whereat the sections are joined to each other and which allows independent vertical movement of the wing section relative to the main section. The folding mechanism further includes limit stops for limiting relative movement between the wing and main sections. Moreover, the agricultural implement can include a driver for effecting powered movement of the wing section relative to the main section.
