ABSTRACT:
A primary tillage apparatus includes a plurality of primary tillage tools and a coulter assembly for each primary tillage tool including first and second coulters positioned directly forward of the primary tillage tool, the coulters being mounted to diverge in a v-shape relative to the direction of travel such that the separation between the edges of the coulters increases in a rearward direction, and concave working surfaces of the coulters face outwardly away from one another, the weight of the implement frame and the action of the primary tillage tools causing the coulters to penetrate the soil ahead of the tillage tool and to press into any residue encountered, the cutting edges of the coulters gripping the residue and drawing the residue outwardly in opposite directions, tearing the residue in two and clearing the residue to the sides and out of the path of the primary tillage tool located rearwardly of the coulter assembly.
