OPERATION AND MAINTENANCE
Hydraulic Fold System
1. The In-Row Ripper is equipped with a hydraulic fold
system to raise and lower the wing frames for narrow
transport.
2. Be sure the system is fully charged with hydraulic oil
before attempting to fold/unfold the unit. Air in the
system can allow uncontrolled dropping of the wing
frames causing serious personal injury or machine
damage. The system needs to be charged with oil
initially and any time the system has been opened for
repair such as cylinder, hose or fitting
replacement/repair.
3. To charge the system, carefully hitch the In-Row
Ripper to the tractor. Check the tractor hydraulic fluid
level to make sure it is full of the manufacturer's
recommended hydraulic fluid. Connect the cylinder
hoses to the tractor and fully extend and retract the
cylinders several times.
NOTE
The Rigid Shear Bolt (RSB) Shank Clamp and the
Auto-Reset Hydraulic Shank Clamp fold 180
The Auto-Rest Spring Shank Clamp does not fold to 180
degrees.
The cylinder rod travel should be smooth and
positive when all air has been purged from the
system. Due to large amounts of hydraulic oil
required, recheck the tractor fluid level to make sure
it is within proper operating limits.
4. The hydraulic fold system is equipped with restrictors
in the rod end of cylinders to prevent uncontrolled
falling of wing frames when unfolding. Removal or
improper assembly of these restrictors can cause the
machine to fold improperly and result in serious
machine damage.
WARNING
Escaping hydraulic fluid can cause serious
personal injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands.
Figure 4-6.
Keep all components (cylinders,
hoses, fittings etc.) in good repair.
5. To fold/unfold the wing frames, find a level area large
enough to accommodate the In-Row Ripper when it
is fully unfolded. The tractor should be stopped and
not moving with the unit fully raised.
6. To lock the Wing Assembly down, remove the pin
from the unlocked position, and into the locking
position.
See Figure 4-5.

The wing fold hydraulic system MUST be
operated in float once the wings are unfolded OR
the wings MUST be locked down. Failure to do so
may result in wing fold cylinder damage.
