A large field cultivator has forward and rear wing frames that are articulated to a main frame between a field position in which they extend laterally and a transport position in which they pivot forward and rearward about an axis substantially perpendicular to the plane of the frames in the field position. A pair of flip up frames secured to the aft frames pivot out of the way so that the rear wing frame assemblies may be pivoted inward to the transport position.

A transport arrangement for an agricultural machine having a suspension system. The transport arrangement includes a header unit a tongue arrangement and a retaining system. The header unit is carried by the suspension system. The tongue arrangement is coupled to the suspension system, and is pivotal about an axis relative to the header unit and the suspension system. The retaining system is configured to releasably couple the tongue arrangement to the header unit and/or the suspension system to thereby retain the header unit in an elevated position.
