Charging Fold Hydraulics
The fold/unfold functions are
on a hydraulic circuit that is
shared with the hydraulic fan on the air cart. The fan
must be disabled during fold and unfold.
1. Check the hydraulic fluid level in the tractor reservoir
and fill to the proper level. A low reservoir level may
draw air back into the system and cause jerky or
uneven cylinder movement. During initial cycling of
new fold cylinders, you will need 6 gallons
(22.5 liters) of oil.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
seek immediate medical attention from a physician familiar
with this type of injury.
2. Remove shipping restraints from the fold cylinders at
the front of the center section.
3. Block, wire or otherwise safely support rod ends, so
that they cannot contact any objects when fully
extended.
Failure to block cylinders before extending will cause machine
damage.
4. Shutoff the cart fan.
5. Turn the drill hydraulic selector valve to the Fold/
Unfold position.
6. Cycle the cylinders completely in and out at least
three times to remove all air from the fold system.
Inspect all hoses, cylinders and fittings for oil leaks.
7. Extend cylinders until cylinder clevis line up with
cylinder lugs. Pin cylinders to lugs.
8. Check the tractor hydraulic reservoir and fill to the
proper level.
