Abstract
The present invention relates to a spray boom comprising an end section connected to a second section by an articulation, a holding device intended to keep the end section in an initial position as long as a pivoting force has not reached a certain triggering threshold. After triggering, the return of the boom to the initial position is due solely to the weight of the end section. The present invention advantageously makes it possible to reduce the knocks generated by the devices of the prior art.
