<p>The disc harrow consists of a frame (1) mounted on wheels (26), and disc gangs (6, 7, 8, 9) connected to frame side members (2, 3, 4, 5) by vertical pivots (14, 15, 16, 17) so they can be moved between working and transport positions. At least some of the disc gangs are in two sections (8'- 8; 9' - 9) with additional pivots that allow them to be raised for transport by means of hydraulic power cylinders (18, 19). The wheels are set at the back of the frame and can also be moved to raised or lower the frame.</p> |
