Abstract

Cette invention concerne un dispositif de commande hydraulique permettant de faire varier la position angulaire entre un tracteur et le timon d'une machine ou d'un outil tracté. Ce dispositif comprend, dans les conduits de raccordement prévus entre le raccord hydraulique du tracteur et le vérin commandant la position angulaire du timon, et en conséquence la position transversale de la machine par rapport au tracteur, une valve d'arrêt supplémentaire qui peut être déplacée entre une position d'arrêt et une position de passage du liquide. Cette valve est montée de telle façon que, dans sa position d'arrêt, le vérin de commande de pivotement soit bloqué, de sorte que la position angulaire entre le timon et le châssis de la machine est fixe. Un agencement de ce type est utilisable sur les machines agricoles et plus spécialement sur les faucheuses-conditionneuses.
