REMARK
• If the ripper is applied while the rear of the machine is
raised from the ground, length of track on ground (A)
decreases. Accordingly, the drawbar pull decreases
and the ripping efficiency lowers.
• If the ripping depth is kept constant, unevenness de-
creases and the dozing efficiency increases.
RIP AT EDGE OF CLIFF
• When ripping at the edge of a cliff, tilt back (B) the ripper to
increase reach at ground line (L).
• While depressing the decelerator pedal, travel forward
slowly. When the ripper point contacts the cliff, tilt in (A) the
ripper.
RIP BASE OF SLOPE
(when giant ripper is installed)
In ripping of the base of a slope, if the ripper tilt back (B) angle
is small and uncrushed portions are left on the slope (1), per-
form the ripping diagonally.
