Ripper With Offset Impacting Means and Slotted Shank Abstract Previously known ripper apparatus comprise an impacting mechanism for applying impact forces to a ripper tip in an in-line relationship. The high spring rate exhibited by the shank induces high peak internal impact forces, dissipates useful energy, and provides relatively shallow cutting depths. In one aspect, the ripper apparatus of this invention overcomes the above problems by providing an offset relationship between a first line of impacting movement of a ripper tip and a second line whereat impacting forces are applied to a shank carrying the ripper tip and by further providing a spring mechanism for ensuring that the impacting forces are transmitted from the second line to the first line directly. In another aspect, the spring mechanism induces an efficient transfer of impact energy from an impacting mechanism to the material being worked by the ripper tip, whether the first and second lines are offset or co-incident.
