Abstract

Un ouvreur de sillon qui comprend un bras longitudinal à parallélogramme muni d'un attelage arrière qui demeure essentiellement à l'horizontale lorsque le bras se déplace vers le haut ou vers le bas. Les ouvreurs de sillon avant et arrière sont fixés à l'attelage arrière. Un bras de tasseur est fixé à l'attelage arrière et s'étend vers l'arrière et vers le bas, et le tasseur est fixé au bras de tasseur et aligné avec un des ouvreurs de sillon. Un dispositif de biais exerce une force de biais sur le bras longitudinal, les ouvreurs de sillon et le tasseur. Les ouvreurs de sillon, le tasseur et l'attelage arrière sont rigides les uns par rapport aux autres en mode de fonctionnement, et la position verticale de fonctionnement d'au moins un ouvreur de sillon relatif au tasseur est réglable afin de faire varier la profondeur du sillon.
