Abstract

Un châssis de charrue réversible est solidaire d'un arbre de renversement rotatif qui est mû par un vérin à double effet 154. Un organe d'arrêt 130, disposé sur l'arbre de renversement au voisinage de la liaison de celui-ci avec le vérin 154, coopère avec des moyens de butée 84 montés dans une tête d'attelage 2 pour contraindre cet arbre à un mouvement de rotation entre des limites angulaires qui correspondent respectivement aux deux positions de travail du châssis de charrue. Applications usuelles des charrues réversibles.
