The present disclosure relates to improvements to ripper boots of the type adapted to be mounted to a bulldozer tine, via carrier 14, for use in cleaving through hard ground. The ripper boot embodied in the present disclosure has particular application in opal mining where sometimes extremely hard ground is to be penetrated and ripped. The ripper boot includes a replaceable ripping tooth 16 having its head shorter than its shaft which is secured within the boot by way of 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 disclosure, 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. |
