1. Park combine and header on a level surface. Ensure
that the combine feederhouse is level.
2. Set header angle to mid-position (between B and C on
the indicator) (not shown).
3. Set the reel fore-aft to mid-position (5 or 6 on reel arm
indicator) (not shown).
4. Lower reel completely.
5. If equipped, set stabilizer/transport wheels to the fully
raised position.
6. Raise header so cutterbar is 6-10 inches (150-250 mm)
above ground.
7. Place header float locks in unlocked (lowered) position.
STEP 1: PRE-ADJUSTMENTS
Complete these 7 steps before adjusting Float.
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.

Notes:
1. Keep header angle
as shallow as
possible. Center link
position depends on
skid shoe and
stabilizer wheel
position. Set header
angle and skid shoe
position to maxi-
mize 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.
