ABSTRACT:
A spring-cushioned coulter running ahead of the applicator for cutting an initial slot in any residue and for providing a break line for the soil to be parted by the trailing shank. The trailing shank, in turn, spreads the initial slot, and deepens it, for the entry of a slurry delivery tube welded behind the shank. At the bottom of the shank is a shoe having a pair of side wings. A downward and outward slope of the wings creates a flat, peaked soil profile ("sole") beneath the wings having sides which slope downwardly and outwardly, conforming to the shape of the wings. The lift surfaces of the wings slightly raise the soil laterally of the shank from the center toward the ends of the wings to provide slots or fissures above the sloped edges of the sole, permitting, and promoting the lateral distribution of the slurry.
