A reversing arrangement for the frame comprises two hydraulic reverse cylinders (6, 7). The reversing arrangement also has an auxiliary reverse device comprising a resilient, energy storing actuator assembly (8) for storing during the first half of the frame pivoting movement and resiliently releasing this energy during the second half thereof. |
