Purge Hydraulic System
DANGER
!
To avoid serious injury or death:
Never remove or install a folding wing cylinder with cylinder
rod retracted and wing folded-up. The wing is unstable
without its folding cylinder and can suddenly fall. Also, air
trapped in a new or repaired cylinder will drop the wing
suddenly when lowering the wing. Either situation can render
the cutter inoperable and cause serious bodily injury or death.
WARNING
!
To avoid serious injury or death:
Be sure center and wing decks are lowered to the ground and
all hydraulic pressure is relieved before disconnecting any
hydraulic lines or fittings to purge the hydraulic system.
Wing Fold Cylinder
Refer to Figure 1-26:
1. Lower center deck until it is supported by stroke
control flip spacers (#6) on hydraulic cylinder (#4).
2. Lower wing decks until they rest on the ground.
3. See
“Tractor Shutdown Procedure” on page 15.
Shut tractor down properly and move deck lift control
lever back and forth to relieve all hydraulic pressure.
4. Slightly loosen hydraulic hose fitting (#2) on right-
hand wing cylinder (#1) to allow air to escape.
5. Restart tractor and slowly activate tractor control
lever to retract wing cylinder (#1), and to purge
trapped air from the hydraulic system.
6. Shut tractor down properly. See “Tractor Shutdown
Procedure” on page 15.
7. Tighten hose fitting (#2) at right-hand wing cylinder.

Refer to Figure 1-26:
1. Move all hydraulic stroke control flip spacers (#6) to
open position, then proceed to lower center deck.
2. See
“Tractor Shutdown Procedure”
on page 15.
Shut tractor down properly and move deck lift control
lever back and forth to relieve all hydraulic pressure.
3. Slightly loosen hydraulic hose fitting (#5) on deck lift
cylinder (#4) to allow air to escape.
4. Restart tractor and slowly activate tractor control lift
lever to extend lift cylinder (#4) and to purge trapped
air from the hydraulic system.
