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.
