Abstract
A ripper of an earthworking apparatus includes a shank with a tapered, forwardly projecting lower end portion that has a blunt extremity, a detachable hollow shin protector which embraces the lower end portion of the shank, both to reinforce said lower end portion and to transfer some ripping forces to the upper portion of the shank which is stronger than the tapered lower end portion, and a one-piece detachable ripper tip which has a rearward mounting stub provided with spaced control surfaces that abut mating control surfaces on the shank and/or the shin protector to positively position the ripper tip and to transfer certain ripping forces through the shin protector to the upper portion of the shank.
