The present invention relates to improvements to ripper boots of the type adapted to be mounted to a bulldozer type for use in cleaving through hard ground. The ripper boot embodied in the present invention has particular application in opal mining where sometimes extremely hard ground is to be penetrated and ripped. The ripped boot includes a replaceable ripping tooth which is secured within the boot by way of an interference fit so that during use. it does not rotate. The interference fit prevents particular matter from entering between the walls of the tooth and the associated socket. In further forms of the invention, the replaceable ripping tooth is angled upwardly with respect to the carrier so that the angle of attack of the ripping tooth is raised so that it is almost parallel with the ground. The ripper boot provides a number of benefits including improved cleaving effect, reduced chatter and drag, reduced wear and tear, and reduced load on associated machinery.
