  • Patent number: 4295532
    Abstract: A double disc attachment for planters, operating to present a debris-cleared area ahead of the furrow opener of the planter, has one of the discs peripherally fluted so that the discs cooperate in their debris-clearing function rather than work in opposition to one another. The fluting permits lateral displacement by the other disc of debris which might otherwise be contacted simultaneously by the soil-penetrating cutter disc and left lying across the path of the oncoming furrow opener. The discs are properly oriented insofar as tilt, spacing, convergence, relative overlapping and lead are concerned, with at least certain of such relative positioning and depth being adjustable to accommodate for various conditions.
