Driveline Clearance Check
Check driveline for adequate clearance under all ranges
of cutter height.
1. With driveline attached to the tractor, slowly raise and
lower cutter to its upper and lower limits while
observing clearances between hitch and driveline.
2. Adjust tractor drawbar height and length if driveline
interferes. See
on page 15 for
correct placement of tractor drawbar.
3. Cycle hydraulic lift system several times to purge
hydraulic lift system of trapped air. See
NOTE:
The lift cylinders should raise the cutter up
while pushing the control lever forward and lower
while pulling the lever back. Switch connections at
the duplex outlet if lift control lever works opposite.

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.
Be sure tractor reservoir is filled properly before
operating hydraulic cylinders. If tractor reservoir is low on
hydraulic fluid, there is a chance of drawing air into the
system causing jerky or uneven cylinder movements.
The wing deck lift cylinder may be purged as follows:
1. With wing deck lowered to the ground, shut tractor off
and move hydraulic control lever for the wing back
and forth to relieve all hydraulic pressure.
2. Loosen hydraulic hose (#3) slightly at wing cylinder
elbow (#2) to allow air and fluid to escape.
3. Restart tractor and slowly activate tractor control
lever to retract wing cylinder and to purge trapped air.
4. Once air is purged from the hydraulic system for the
wing cylinders, tighten hydraulic hose fittings. at
elbow (#2)
