Abstract

L'invention concerne un mécanisme de réglage et de renversement de marche pour une charrue réversible. Ce mécanisme comprend un cylindre hydraulique (8) à ''mémoire hydraulique'' pour le réglage de la largeur de sillon. Les chambres à huile définies de part et d'autres du piston (15) du cylindre (8) communiquent avec un réservoir (24) via deux soupapes de retenue à asservissement (26, 25) et une seconde vanne de commande de direction (10). La chambre (31) définie dans le cylindre (8) communique, d'une part, avec un cylindre hydraulique (7) pour le renversement de marche de la charrue via une première soupape de retenue (14) et d'autre part, avec le réservoir (24), via une vanne de régulation de débit (28) et une première vanne de commande de direction (9).
