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 (11,11a) of this invention overcomes the above problems by providing an offset relationship between a first line (L.sub.1) of impacting movement of a ripper tip (13) and a second line (L.sub.2) whereat impacting forces are applied to a shank (14,14a) carrying the ripper tip (13) and by further providing a spring mechanism (25,25a) for ensuring that the impacting forces are transmitted from the second line (L.sub.2) to the first line (L.sub.1) directly. In another aspect, the spring mechanism (25,25b) induces an efficient transfer of impact energy from an impacting mechanism (17) to the material being worked by the ripper tip (13), whether the first (L.sub.1) and second (L.sub.2) lines are offset or coincident.
In a ripper apparatus (11,11a) having a movable support member (14,14a), a ripper tip (13) mounted on said support member and disposed for impacting movement along a first line (L.sub.1), and an impacting means (17) for intermittently applying an impacting force to said support member (14,14a) in the direction of a second line (L.sub.2), the improvement comprising
