A ground penetrating tool for a farm implement shank has a pyramidal tooth provided with a pointed, leading apex and a socket in its trailing end that receives a mating, triangular tongue integral with an upwardly and rearwardly extending mount releasably secured to the shank. The trailing end of the tooth abuts shoulders on the mount to absorb the load on the tooth and further protect a fastener passing transversely through the tooth and tongue for releasably attaching the tooth to the mount.
