Abstract
A unique coulter has a flat band adjacent the peripheral cutting edge to form a slot. Inwardly of this flat band, and on one side of the coulter blade is an inclined compacting surface. The outer, cutting edge of the coulter enters the soil first and as the machine moves forward the compacting surface of the coulter is brought into engagement with one wall of the partially formed slot to firm the soil adjacent the top of the wall. At the rear of the coulter, behind the compacting surface, there is a delivery chute or tube for depositing the fertilizer into the slot formed by the coulter.
