MacDon FlexDraper FD2 Series - Step 2: Checking Header Float; Step 3: Setting Header Float; Step 4: Checking Wing Balance; Step 5: Adjusting Wing Balance

NOTE: Before proceeding to check and adjust the wing balance, ensure the header
oat is set. Refer to Step 3: Seng Header Float for instrucons.
a. Aach ex checker cable (A) to ex checker cable lock (B).
NOTE: Images shown are from the le side.
b. On the side that you are adjusng, move spring handle (A) to the lower (UNLOCK)
posion. Keep the opposite wing locked. You should hear the lock disengage. If
not, use mul-tool (B) to rotate the mechanism so that the lock disengages.
c. On both sides of the oat module, place the header oat locks (shown in
Figure 3) in the locked posion.
d. On the ex checker plate, pinch indicators (A) and (B) together with your ngers.
e. Use mul-tool (C) to rotate the ex checker plate up unl the pin reaches the end
of slot. Lower indicator (B) will move down to give the rst reading.
f. Use mul-tool (C) to rotate the ex checker plate down unl the pin reaches the
end of the slot. Upper indicator (A) will move up to give the second reading.
g. Refer to Figure 10 and interpret the indicator posions as follows:
• Condion A – the wing is too light; make the wing heavier.
• Condion B – the wing is too heavy; make the wing lighter. a. Loosen bolts (C), and rotate spring locks (B).
• To decrease header weight, turn both adjustment bolts (A) equally
clockwise (decreasing the value on the FSI).
• To increase header weight, turn both adjustment bolts (A) equally
counterclockwise (increasing the value on the FSI).
NOTE: Ensure the FSI values are equal on both sides.
b. Aer adjustment, li the end of the header by hand and recheck the
FSI reading.
NOTE: If an adequate header oat cannot be achieved using all the
available adjustments, an oponal heavy duty spring is available. See
your MacDon Dealer or refer to the parts catalog for ordering
informaon.
c. Once the oat adjustment is complete, lock adjustment bolts (A) with
spring locks (B). Ensure that bolt heads (A) are engaged and ghten
bolts (C) to secure the spring locks.
d. Use the combine to fully lower the header. The le and right oat
seng levers will return to their original posions.
WARNING
Do NOT use the mul-tool to release the oat seng lever. Using
the mul-tool to release the oat seng lever can result in injury.
Step 3: Seng Header Float
a. On the le side of the header, li oat seng lever (A) by hand to
remove slack.
b. Fully engage the at end of mul-tool (B) on the oat seng lever.
The mul-tool should be angled toward the front of the oat module.
c. Pull mul-tool (B) toward the back of the oat module unl lever (A) is
locked in place and will not return to its original posion.
d. Move the header up and down by hand several mes to reduce the
eect of fricon.
e. Remove the mul-tool and repeat on the opposite side.
WARNING
Once the oat seng lever has been set, remove the mul-tool
from the lever IMMEDIATELY. If the lever falls to its starng
posion while the mul-tool is engaged with it, injury can occur.
f. On the le side of the oat module, inspect smaller oat seng
indicator (FSI) (A). Arm (B) on the FSI should point to the number 2.
• If the FSI points to a value higher than 2, the header is too heavy.
• If the FSI points to a value lower than 2, the header is too light.
NOTE: The larger numbers (C) indicate the oat height while operang
the header in the eld.
NOTE: If necessary, adjust the oat values to suit crop and eld
condions. For more informaon, refer to the header operator’s
manual.
Step 2: Checking Header Float
Figure 5: Checking Float – Le Side Shown, View from Rear
Figure 4: Checking Float – Le Side Shown, View from Rear
a. If the wing is too light (Condion A), make it heavier by turning adjuster bolt (D)
to move clevis (E) in direcon (F).
b. If the wing is too heavy (Condion B), make it lighter by turning adjuster bolt (D)
to move clevis (E) in direcon (G).
c. Recheck the wing balance. Adjust as required unl the wing is balanced
(Condion C).
d. Move the spring handle to the upper (LOCK) posion.
e. If the lock does not engage, move the wing up and down with the mul-tool unl
it locks.
f. Detach the ex checker cable from the ex checker lock.
g. Repeat on the other side.
h. Return the mul-tool to its storage locaon, and reinstall the linkage cover.
