Abstract

Ce dispositif d'attelage à trois points pour tracteur agricole, du type comprenant une barre supérieure 4 à longueur variable suspendue par un cadre 2 lui-même articulé sur les barres inferieures 1, comprend une tringlerie 5 qui relie le cadre d'attelage 2 au mécanisme 1 de blocage de la longueur de la barre supérieure 6 pour libérer ce mécanisme sous l'effet d'une pression exercée de l'extérieur sur le cadre 2. La barre supérieure porte un crochet 8 dont le verrou s'ouvre, sous l'action du cadre d'attelage, lorsqu'on fait descendre les barres inférieures.
