Abstract
A pair of circular, furrow-opening disks, supported by separate, angularly oriented axles, rotatable simultaneously as a unit and converging to a leading zone of interengagement within the ground for preventing soil buildup therebetween, have a wedge-shaped, trailing blade, rigidly supported therebetween immediately ahead of materials gravitating into the furrow, and following at a greater depth, for slicing the series of unplowed scallops at the bottom of the furrow, clearing the furrow bottom of loose soil and forming a truly V-shaped, ridgeless, material-receiving apex compressed into a smooth, firm sidewall formation.
