Purge Hydraulic System

DANGER
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
Be sure center and wing decks are lowered to the ground and
all hydraulic pressure is relieved before disconnecting any
hydraulic lines or fittings between the Rotary Cutter and
tractor hydraulic system.
The wing deck lift cylinder may be purged as follows:
1. With wings lowered to the ground, shut tractor off
and move the wing hydraulic control lever back and
forth to relieve hydraulic pressure at the wing
cylinders.
2. Loosen hydraulic hose fittings slightly at each wing
cylinder to allow air and fluid to escape.
3. Restart tractor and slowly activate tractor control
lever to retract the wing cylinders and to purge
trapped air from the hydraulic system.
4. Once air is purged from the hydraulic system for the
wing cylinders, tighten the hose fittings at each wing
cylinder.
5. Repeat steps 1 to 4 above to purge center deck lift
cylinder. Make sure the cutter skid shoes are resting
on the ground or the lift cylinder is fully retracted
against the stroke control spacers and all hydraulic
pressure is relieved at the lift cylinder before
loosening the lift cylinder hose fitting.
Unhooking The Rotary Cutter
1. See “Long Term Storage” on page 37 if parking the
cutter for long periods and end of season.
2. Disengage PTO, park on a level hard surface. Place
gear selector in park, and set park brake.
3. Wait for blades to come to a complete stop and then
fold wings up to transport position.
Refer to Figure 3-3 on page 25:
4. Remove hairpin clips (#1) from storage pins (#2).
Refer to Figure 3-4 on page 25:
5. Swing transport lock bars (#3) down and place over
lock pins (#4). Secure with hairpin clips (#1).
Refer to Figure 2-2 on page 20:
6. Remove stroke control spacers from center hydraulic
cylinder and lower cutter until front skids are resting
on the ground. Replace stroke control spacers as
needed to support wheels at this position.
7. With tractor gear selector in park and park brake set,
shut tractor engine off, and remove switch key. Move
cylinder lift levers back and forth to release hydraulic
line pressure.
Figure 1-11
Refer to Figure 1-11:
8. Remove parking jack (#3) from the left-hand wing
deck and attach to the cutter hitch. Secure parking
jack in place with attached jack pin (#8).
9. Unhook hydraulic hoses (#7), driveline safety
chain (#6), driveline (#5), and hitch safety chain (#4)
from tractor. Store hose ends in hose support loop.
10. Unhook driveline from tractor PTO shaft.
11. Adjust parking jack up or down as needed and
remove connecting pin or bolt (#1) (See Figure 1-11
above, Figure 1-6 on page 15, or Figure 1-8 on
page 16.
12. Drive tractor away from cutter and then lower parking
jack until cutter is resting on its front skid shoes.
13. Replace connecting pin/bolt (#1) to the cutter as
follows:
a. If unhooking from standard clevis or double clevis
hitch, replace connecting pin/bolt to cutter hitch.
b. If unhooking swivel clevis or bar-tite hitch, remove
hitch components from tractor tongue and
reattach to cutter hitch with connecting bolt.
