STEP 18. ADJUST CENTER-LINK
A. MECHANICAL LINK
a. Lower header so that cutter bar is resting on the
ground. Stop engine, and remove key.
CAUTION
Stop engine, and remove key from ignition
before leaving operator’s seat for any
reason. A child or even a pet could engage
an idling machine.
b. Loosen nut (A).
c. Rotate the turnbuckle sleeve (B) to obtain
22-2/5 in. (570 mm) dimension.
d. Snug up nut (A), but do NOT over-tighten. A
slight tap with a small hammer is sufficient.
B. HYDRAULIC LINK
a. Operate tractor hydraulic control so that gauge
(C) is approximately at the middle hole.
STEP 19. ADJUST FLOAT SPRINGS
Float springs were factory-set to provide the
minimum width for shipping, and need to be
readjusted prior to use.
CAUTION
To prevent damage to front panel on carrier
frame, do NOT raise header with lift
cylinders before backing off float spring
drawbolts.
a. Unlock jam nuts (D) from float springs.
b. Turn drawbolts (E) counterclockwise to release
spring tension to 11-4/5 in. (300 mm) dimension
shown. There are two springs on each side
to adjust.
CAUTION
To prevent damage to the float spring
system, do NOT lower the header before
tightening jam nuts (A) against the springs.
IMPORTANT
Because header weight transfers to
outside tire whenever header is swung
from one side to the other, tires must be
fully inflated (30 psi [207 kPa]) to minimize
effects on header float.
c. Lift either end of the header just off the ground.
Header flotation springs are normally set, so
70 lbf (311 N) force is required to lift the header.
d. Adjust springs as required.
e. Tighten jam nuts (D) against float springs.
