Abstract
An insert for use in an agricultural tool having a cutting edge for forming a furrow. The insert includes an elongated wedge having a leading end, a trailing end, a top surface, a first side surface and a second opposing side surface coterminous therewith defining a longitudinally extending lowermost edge. The first and second side surface converge from the trailing end to the leading end and diverge from the lowermost edge to the top surface to form a v-shape leading end. In a preferred embodiment the insert includes a means for aligning the lowermost edge of the insert with the cutting edge of the tool.
