The invention relates to an agricultural machine that has two sections hinged relative to each other, at least one oblong hole being made in one of the two sections, the machine including a connecting device that has an actuator configured to cause one section to pivot relative to the other, and a travel stop, the actuator supporting a movable pivot rod, with a longitudinal axis transverse to the oblong hole, the movable pivot rod being positioned to slide in the length of the oblong hole, the travel stop having a blocking state in which it obstructs the oblong hole, thereby limiting the sliding of the pivot rod in the oblong hole, the travel stop being able to achieve the blocking state from a free state in which it is mounted in a movable rotating manner relative to the oblong hole.
