have internal springs on both sides.

e. Tighten spring drawbolt so that distance between
spring anchor to locknut is approximately 5 inches
(127 mm).
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 mower conditioner is swung
from one side to the other, tires must be
fully inflated to 30 psi (207 kPa) to minimize
effects on header float.
f. Lift either end of the header just off the ground.
Header flotation springs are normally set to 95-
105 lbf (426-471 N) force is required to lift the
header.
g. Adjust springs as required with drawbolt (B).
h. Tighten jam nuts (A) securely against float
springs.
