ABSTRACT OF THE DISCLOSURE The present invention relates to an agricultural cultivator frame having a centre and two wing sections pivotally attached to the centre section for rotation about horizontal axes in the direction of travel for movement between a substantially horizontal field or working position and a substantially vertical transport position. Support wheels are attached adjustably to the frame by a transverse rockshaft extending the width of the cultivator and controlling the elevation of the frame above ground level. The hitch is pivotally attached to the frame for automatic levelling. The rockshaft wing sections are connected to the rockshaft centre section by a universal joint. The rockshaft wing sections are pivotally attached to the wing section for movement about multiple axes and provide for longitudinal displacement relative to the frame.
