The frame for an agricultural machine has a central section (16) and outer sections (12, 14) which can swivel from a working position where they are in line with the central section to a transport position where they are at right angles to it. They are operated by hydraulic cylinders (72, 74) and are mounted on pivots (34, 38) at their inner ends. Triangular grippers (60, 62) at the outer ends grip the ends of a central triangular plate (70) when the frame sections have been swiveled back. |
