MacDon D65 Combine Header Quick Card - Manual

1. Park combine on a level surface. Ensure that the combine feeder-
house is level.
2. Adjust header so cutterbar is 8-12 inches (200–300 mm) off the
ground.
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 decal).
5. Lower reel completely. Shut down the combine.
6. Place header float locks in un locked (lowered) position.
7. If equipped, set stabilizer/transport wheels to the fully raised position.
STEP 1: PRE-ADJUSTMENTS
Complete before adjusting FLOAT.
IMPORTANT
Be sure to have read your operator’s
manual, and complete all set-up tasks
before setting header float and wing
balance.
1. Remove the special torque wrench (A) from storage position on right
side of the CA25 combine adapter.
2. Place torque wrench (A) on the float lock at (B). Note change in orien-
tation of wrench between left and right side.
3. Push down on torque wrench (A) until bell crank (C) rotates forward.
4. Continue pushing down until indicator (D) on wrench reaches a MAXI-
MUM reading and begins to decrease. Note the maximum reading.
5. Repeat above steps for opposite side.
6. The readings should match the values in TABLE 1. HEADER FLOAT.
STEP 2: CHECK HEADER FLOAT
1. Refer to TABLE 1 for recommended initial float setting:
• If reading on wrench is high, header is heavy, so increase float.
• If reading on wrench is low, header is light, so decrease float.
2. Adjust header float to match values in TABLE 1. Turn each bolt pair
equal amounts.
• To increase float (lighter header), tighten (clockwise) float spring
bolts (A) and (B).
• To decrease float (heavier header), loosen (counter clockwise)
float spring bolts (A) and (B).
• 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 (B) 2 turns.
