OPERATION AND MAINTENANCE
2.
To charge the system, unpin the end(s) of the fold
cylinders, and position them so they can extend and
retract without contacting any frames or other parts.
a. Carefully hitch the Finisholl to the tractor and
connect the hydraulic fold hoses. Check the
tractor hydraulic fluid level to make sure it is full
of the manufacturer's recommended hydraulic
fluid. Connect the hydraulic fold and lift hoses to
the tractor.
b. Fully extend the lift cylinders and raise the
implement.
c. Extend and retract the fold cylinders several
times. The fold 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.
d. Reconnect the fold cylinder pins to the wings.
3. The hydraulic fold system is equipped with restrictors
in the cylinders to prevent uncontrolled falling of wing
frames when folding/unfolding. Removal or improper
assembly of these restrictors can cause the machine
to fold improperly and result in serious machine
damage.
4. To fold/unfold the Finisholl, find a level area large
enough to accommodate the machine when it is fully
unfolded. The tractor should be stopped and not
moving with the implement fully raised. Remove the
wing transport lock pins from the mounts and install
them in the storage locations
NOTE
Failure to remove the wing lock pins when unfolding
will result in serious damage to the implement. Be
sure other people and pets are a safe distance away.
5. 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. When the unit is fully folded, remove the wing
transport lock pins from the storage location and
install in the mounts provided on each side of the
machine
See Figure
6. Maintenance – Regularly check all hydraulic
components. Check for hoses that may have become
worn or pinched. Look for cylinders, valves, hoses, or
fittings that may be leaking hydraulic fluid. Replace or
repair any leaking or defective components
immediately. Unfold, lower the unit to the ground, and
relieve hydraulic pressure before attempting to
service any hydraulic component.

7. Storage - For extended periods of nonuse, it is best
to store the Finisholl inside if possible. If stored
outside, unfold the unit to keep wheels and disc
bearings from filling with rain and/or snow. If the unit
must be stored outside for extended periods, is best
to apply a light coating of oil or grease to exposed
cylinder rods to prevent them from rusting. Grease
the unit at all points

parts.If the unit is stored in the folded position, make
sure the wing transport lock pins are installed to
prevent wing frames settling
Hydraulic Disc Gang System
The optional hydraulic disc gang uses a rephasing lift
system to raise and lower the disc gangs. The rephasing
cylinders are plumbed in series with the largest cylinder
on the center frame progressively getting smaller to the
last wing cylinder. It is important that the cylinders be
connected in the proper series for the disc gang lift
system to operate correctly. When the cylinders are fully
extended and held in this position, oil is able to flow
through the cylinders (or rephase) and allow the cylinders
to operate in sync.This also allows the system to purge
any air that may enter the system without having to
loosen or crack hydraulic lines.
The hydraulic disc gang system is not filled with oil
and should be purged of air before folding,
transporting, or field operations.
a. Carefully hitch the Finisholl to the tractor and
connect the hydraulic lift hoses. Check to make
sure the tractor hydraulic reservoir is full of the
manufacturer's recommended oil. Slowly extend
the disc gang cylinders to raise the disc gangs,
and continue to hold the hydraulic lever until all
lift cylinders are fully extended.
NOTE
Note: Watch the disc gangs carefully when initially
charging with oil to make sure the disc gangs do not
bottom out on the frame when cycling. Disc gang
may require leveling before being able to fully cycle.
b. Lower and raise the disc gangs to verify that all
cylinders are working simultaneously throughout
the stroke.
c.
If the cylinders are not working evenly or
together, fully extend the lift cylinders and
continue to hold the lever to purge any remaining
air. Do not loosen any hoses or fittings.
d. Recheck the tractor reservoir to make sure it is
within operating limits.
