Abstract
An agricultural machine includes a hitching support, at least one tool or group of tools that can be transferred between an operational position and a raised position, at least one support arm that is connected to the hitching support via two joints and to the tool or group of tools at an assembly location, and a safety device for performing a safety movement under the effect of pressure. At least one first safety movement phase is carried out around the first joint or around one of the two joints. The safety device includes at least one guiding device to allow for a variation in a distance between the other of the two joints and the assembly location when the rearward rotation is carried out around the first joint.
