1. Park combine and header on a level surface. Ensure
that the combine feederhouse is level.
2. Place wing lock spring handles in the locked position.
3. Set guard angle to mid-position (between B and C on the
indicator).
4. Set the reel fore-aft to mid-position (5 or 6 on reel arm
indicator).
5. Lower reel completely.
6. If equipped, set stabilizer/transport wheels to the fully
raised position.
7. Raise header so cutterbar is 6-10 inches (150-250 mm)
above ground.
8. Place header float locks in unlocked (lowered) position.
STEP 1: PRE-ADJUSTMENTS
Complete before adjusting Float or Wing Balance.
1. Remove the special torque wrench (A) from storage
position on RH side of the CA25 combine adapter.
2. Place torque wrench (A) on the float lock at (B).
3. Push down on torque wrench (A) until bell crank (C)
rotates forward.
4. Continue pushing down until indicator (D) on wrench
reaches a MAXIMUM reading and begins to decrease.
Note the maximum reading.
5. Refer to TABLE 1 for recommended initial float setting:
 If reading on wrench is high, header is heavy, and
float needs to be increased.
 If reading on wrench is low, header is light, and float
needs to be decreased.
6. Adjust header float to match values in TABLE 1.
Turn each bolt pair equal amounts.
 To increase float (lighten header), tighten (clockwise)
float spring bolts (E) and (F).
 To decrease float (increase header weight), loosen
(counter clockwise) float spring bolts (E) and (F).
 Ensure wrench reading is equal on both sides.
NOTE
For 40 and 45 FT Double Knife Headers,
adjust float as above, and then loosen
RIGHT SIDE FLOAT spring bolts (F)
2 turns.

TABLE 1
THESE ARE THE 4 STEPS TO SET
HEADER FLOAT AND WING BALANCE
IMPORTANT
Be sure to have read your Operator’s
Manual, and complete all set-up tasks
before setting Header Float and Wing
Balance.
Notes:
1.Keep guard angle
as shallow as
possible. Center link
position depends on
skid shoe and stabi-
lizer wheel position.
Set guard angle and
skid shoe position
to maximize amount
of poly on the
ground while
maintaining desired
cutting height.
2.Minimum knife drive
pulley RPM.
Applicable to only
single knife drive
headers.
3.Percentage above
ground speed.
4.Cutting height is
controlled with a
combination of skid
shoes, stabilizer
wheels and header
angle. By support-
ing header with skid
shoes or stabilizer
wheels, the adapter
floats header over
obstacles and
ground contours.
5.Available through
your Dealer Parts
Department. Set
divider rods to
highest or second to
highest position in
standing crop. This
position allows the
dividers to level the
down crop for a
cleaner cut at the
ends of the header.
Whisker divider not
required on both
ends of header.

1. Use the readings taken in STEP 3, and the images on
this page to determine if the wing is too heavy or too
light.
2. Loosen the clevis bolt for the wing requiring adjustment.
3. Balance the wing according to the Wing Balance
Adjustment Detail image below.
4. Tighten the clevis bolt.
5. Repeat STEPS 3 and 4 (if necessary) for the opposite
wing.
6. Re-install poly linkage covers.
STEP 4: ADJUST WING BALANCE
Left Side Wing Balance Adjustment Detail Right Side Wing Balance Adjustment Detail
1. Remove poly linkage covers.
2. Place torque wrench (A) on bolt (G).
3. Move spring handle (H) to lower position so that lock
link drops into lower slot.
NOTE
If lock link does not engage lower slot,
move with torque wrench (A) until lock
link moves into slot.
4. Move wing upward with torque wrench (A) until pointer
lower alignment tab (J) lines up with upper edge of top
link (K). Note indicator reading (L) on wrench.
5. Move wing downward with torque wrench (A) until
pointer upper alignment tab (M) lines up with the lower
edge of the top link (K). Note indicator reading (L) on
the wrench.
6. If the difference between the readings is 1 or less, the
wing is balanced and no further adjustment is required.
7. If the difference between the readings is more than 1,
the wing is imbalanced. Record the readings and
proceed to STEP 4.
