MacDon Harvest Header D65 Quick Start Manual

STEP 1: PRE-ADJUSTMENTS
Complete these 7 steps before adjusting Float.
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 2: SET HEADER 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.
