Hydraulic Fold System
1.
The disc 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 disc to the
tractor. Unpin the end(s) of the fold cylinders, and
position them so they can extend and retract without
contacting any frames or other parts. 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. 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
5.
To fold/unfold the disc, find a level area large enough
to accommodate the disc when it is fully unfolded.
The tractor should be stopped and not moving with
the unit fully raised. Remove the transport lock pins
from the mounts and install them in the storage
locations
and
.)
IMPORTANT
Failure to remove the lock pins when unfolding will
result in serious damage to the implement. Be sure
other people and pets are a safe distance away.
6.
Slowly engage the tractor lever and fold/unfold the
wing frames. When the wings are unfolded, continue
holding the tractor lever to fully extend all fold
cylinders. This will allow the wings to fully flex in the
field.
7.
When the unit is fully folded, remove the transport
lock pins from the storage location and install in the
mounts provided on each side of the machine.

Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands
Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
