Abstract

Machine agricole avec une tête d’attelage munie d’un dispositif de verrouillage bloquant de sa traverse L’invention concerne une machine agricole, en particulier charrue, comprenant un bâti portant au moins un outil et une tête d’attelage (3) pour sa liaison avec un dispositif d’attelage trois points d’un véhicule tracteur, la tête d’attelage (3) comprenant, d’une part, une traverse d’attelage (4) comportant à ses deux extrémités opposées des attaches (5) destinées à venir en engagement avec les deux points d’attelage inférieurs du dispositif d’attelage trois points, et, d’autre part, une pièce (6) d’assemblage articulé pour ladite traverse (4), qui reçoit cette traverse (4) dans un espace plan de montage (PM) dans lequel elle est mobile avec guidage en translation et en rotation, les mouvements de rotation relatifs entre la traverse (4) et la pièce d’assemblage articulé (6) étant limités par des butées, respectivement avant (9) et arrière (10). Machine caractérisée en ce que la tête d’attelage (3) comprend un dispositif de verrouillage (11) à au moins deux verrous (12, 12’) et à commande unique (13), configurés pour bloquer en position, en translation et en rotation, la traverse d’attelage (4) par rapport à la pièce d’assemblage articulé (6), ce en coopération avec au moins l’une des butées (9, 10).
