The tools have a primary tool (6), a depth control device (7) and a secondary tool (8) placed in upstream of the primary tool. The secondary tool is fixed to a connection element (4) by a deformable quadrilateral part (9) connected to a frame (2). An arm (12) of the deformable quadrilateral part is common to the connection element, where the element is connected to the frame by an articulation (5). The arm is articulated at each of its ends on the connection element. One of the ends of the arm is merged with the articulation. An independent claim is also included for an agricultural machine. |
