Locking the ripper bar
To install the locking pins for the ripper bar first raise the machine with the main lift cylinders.
Place rated workshop stands or blocks of hard timber under the mouldboard and lower the
machine onto them. If the scraper is to be disconnected from the tractor, place stands or timber
under the tie down lugs on the front cross beam and lower the machine onto them. Once the
machine is secure, raise the ripper bar all the way up. Hold the controls in this position for a
second or two. The holes in the lower ripper linkage and ripper cylinder mounts should be aligned
now. Remove the lynch pin from the safety pin and insert into the locations as shown below. Re-
fit the lynch pins into the safety pins after the safety pins have been inserted. Make sure both
pins have been properly installed before undertaking maintenance on the rippers.
It is essential that the pins be positioned into their safety locations by
reaching over the top of the front cross beam and not climbing underneath
the cross beam. It is recommended that the installation of the lynch pins be
done after the scraper hydraulic lines have been disconnected from the
tractor and before any maintenance operations are conducted.
