CA 2528468

A seeding and fertilizing apparatus comprises a plurality of seed assemblies each comprising a trailing arm pivotally connected at a front end thereof to the frame and a packer wheel rotatably attached to rear end thereof. A seed knife is attached to the trailing arm ahead of the packer wheel which rolls along the seed furrow created by the knife. A vertical position of the knife with respect to the packer wheel is adjustable, and a bias device is operative to exert a downward bias force on the trailing arm. A plurality of fertilizer assemblies each comprises a fertilizer disc rotatably mounted to the frame such that a vertical position of the disc with respect to the implement frame is adjustable. The seed assemblies and fertilizer assemblies are oriented laterally such that each fertilizer furrow is located between adjacent seed furrows.

Appareil d'ensemencement et de fertilisation qui comprend plusieurs ensembles d'ensemencement, chacun d'eux étant doté d'un bras oscillant relié au châssis de manière pivotante par son extrémité avant et d'une roue tasseuse, fixée de manière rotative à son extrémité arrière. Une lame est fixée au bras oscillant devant la roue tasseuse, laquelle roule en suivant le sillon de semences créé par la lame. La position de la lame, verticale par rapport à la roue tasseuse, est réglable, et un dispositif de sollicitation exerce une force de sollicitation descendante sur le bras oscillant. Plusieurs ensembles de fertilisation comprennent chacun un disque de fertilisation monté de manière rotative au châssis de manière à ce que la position du disque, verticale par rapport au châssis de l'instrument, soit réglable. Les ensembles d'ensemencement et de fertilisation sont orientés latéralement de manière à ce que chaque sillon d'engrais soit tracé entre des sillons de semences adjacents.
