A ripper carriage assembly has a transverse cross beam fixedly mounted at a central portion of the cross beam to a ripper implement support structure. The distal ends of arms extending outwardly from the central portion of the transverse cross beam are adapted for pivotal connection to a pitch control mechanism. Stress relief notches are formed in the transverse cross beam at a position between the distal ends of the arms and the central rigidly mounted portion of the beam. Energy generated as a. result of the ripper tip twisting upon impact with rock or other solid objects in hardened ground is stored in the transverse cross beam, and subsequently returned to the ripper tip to bring the tip into a desired operational orientation.
