An agricultural tool including a disc blade incorporating hard wear resistant inserts for attachment to an axial member of an agricultural tool for rotation through the soil. The disc blade includes parallel spaced flat round front and rear surfaces having a central cylindrical opening. The front surface tapers radially outwardly to the rear surface thereby defining a common outer rim having a knife edge. A plurality of notches are spaced circumferentially along the front surface of the disc blade and inwardly from the outer edge of the front surface of the disc blade. The notches are configured to receive a plurality of hard wear resistant inserts to provide improved wear resistance.
