ABSTRACT:
A coulter arrangement and associated drill are provided that are useful in all types of soil, minimize dragging of vegetation into the seed slots, and insure sufficient covering of seed with soil. First and second dished discs are located on frame members, the second disc intercepting the soil displaced by the frist disc. A third dished disc having concave and convex faces and smaller in diameter than the first disc is mounted on another frame member. The third disc is mounted with respect to the first disc and a seed delivery tube so that the third disc removes trash and plant debris from the slot cut by the first disc, and guides seeds from the seed delivery tube directly into the slot.
