<p>The device has an elastically deformable connection unit (7) rigidly fixed on a mobile frame (2). A reaction bar (6) is mounted to a ball (50) with respect to the frame. An agricultural tool (3) is fixedly assembled at a lower end (5) of an agricultural tool arm (8). A fixation point (23) of the unit on the frame is located behind the arm relative to forward direction (f). A ball assembly zone of the reaction bar formed on the frame is located in front of the arm relative to the forward direction.</p> |
