The invention comprises a harrow attachment for grain drills, having a pole extending horizontally across the rearward end of the grain drill and attached thereto. A pair of arm are pivotally mounted to the pole and a dual pair of levers are pivotally mounted to the arms with harrow teeth mounted to the lower end of the lever arms. The arms may be pivoted upwardly about the axis of the pole against the back of the grain drill with gravity causing the levers to pivot downward with the harrow teeth attached thereto to pivot the harrow teeth compactly against the grain drill.
