The invention concerns an earth ripping attachment which can be mounted on the bucket of a dragline and used to break through cap rock, frozen earth, or other difficult to dig overburden. The device has a base adapted to fit against the underside of the bucket. An upwardly folded lip at one end of the base receives and engages the digging edge of the bucket, while means provided at the other end connects to the bucket hoist rigging to secure the attachment in place. One or more ripper teeth are spaced below the base and point in the drag direction. With this attachment the full drag force of the dragline and the weight of the bucket are utilized in the ripping operation.
