The ripper frame (18) accommodates a ripper shank (16) in a channel (31) within the ripper frame (18). A pin (36) is provided to pass through the at least one slot (37) and through a through-way (35) in the ripper shank (16) to constrain the ripper shank (16) within the ripper frame (18). At least one pressure source supplies pressure to the ripper shank (16) to engage the ripper shank (16) in a position.</p> |
