A seed drill includes a novel planting assembly combining press wheels for packing angular sides of a furrow and a runner immediately behind and longitudinally aligned with the press wheel. The runner includes an arcuate front edge that is juxtaposed immediately behind the coulter, thereby preventing accumulation of field trash between them. The runner extends rearwardly from beneath the press wheel and is transversely guided on the supporting vehicle frame of the drill to maintain it in longitudinal alignment within an open longitudinal slot cut through the soil and intersecting the base of the packed furrow. Seed is dropped into the open slot prior to being covered with soil. Moist soil can be packed along the sides of the furrow to maintain the furrow in an open condition during seed germination and plant emergence. Highly accurate planting depth control can be achieved, with provision for upward relative movement of the runner as required by encountered field conditions.

Un semoir comprend un ensemble novateur de semis combinant des roues tasseuses pour tasser les côtés angulaires d'un sillon et un patin juste derrière et aligné longitudinalement avec la roue tasseuse. Le patin comporte un bord avant arqué juste derrière le coutre, ce qui prévient l'accumulation de débris entre les deux. Le patin s'étend vers l'arrière depuis le dessous de la roue tasseuse et est guidé transversalement sur le châssis du véhicule porteur du semoir pour qu'il soit maintenu en alignement longitudinal à l'intérieur d'une fente longitudinale ouverte coupée dans la terre et croisant la base du sillon tassé. La graine de semence est déposée dans la fente ouverte puis recouverte de terre. De la terre humide peut être tassée sur les côtés du sillon dans le but de le maintenir ouvert durant la germination et l'apparition des plants. On peut maîtriser avec une grande précision la profondeur de semis grâce au mouvement relatif du patin vers le haut en fonction des particularités du terrain.
