Bleeding Fold Hydraulics (LC40 only)

To function properly, the hydraulics must be free of air. If
hydraulics have not been bled, they will operate with
jerky, uneven motions and could cause wings to drop
rapidly during folding or unfolding. If hydraulics were not
bled during initial implement setup or if you replace a
part in hydraulic system during the life of the implement,
complete the following procedures.

Unfolded Bleeding

Refer to Figure 32

1.

Check hydraulic fluid level in tractor reservoir and fill
to proper level. Add fluid to system as needed.

2.

With implement unfolded and fold cylinders
completely extended, disconnect rod end pins and
swing the cylinders so they will not contact anything
when extended.

3.

Loosen rod end hose fittings

at a JIC connection.



Do not loosen an O-ring boss (ORB) connection for
bleeding. Bleeding at an ORB damages the seal.

4.

Slowly supply oil to rod end of fold cylinders until oil
appears at loosened hose fitting. Tighten fitting and
completely retract fold cylinders.

5.

With cylinders completely retracted, loosen base end
hose fittings

at JIC connection.

6.

Slowly supply oil to base end of fold cylinders until oil
appears at loosened hose fitting. Tighten base end
hose fitting and cycle fold cylinders in and out
several times.

7.

Re-pin cylinder rod clevises.

High Pressure Fluid Hazard:

Only trained personnel should work on system hydraulics!
Check all hydraulic lines and fittings before applying

pressure. Relieve pressure before disconnecting hydraulic

lines. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Fluid escaping from a

very small hole can be almost invisible. Use paper or

cardboard, NOT BODY PARTS, to check for leaks. Escaping
fluid under pressure can have sufficient pressure to penetrate

the skin causing serious injury. If hydraulic fluid is injected

into the skin or eyes, seek immediate medical assistance from a
physician familiar with this type of injury. Within a few hours

gangrene can start to develop. DO NOT DELAY.
