Float Adjustments for Header Models D50/D60/FD70 – 2142/2152/2162
(Supplement to set-up in Operators Manual. See Operators Manual for greater detail.)
This instruction is intended as a quick reference for setting the float on the models listed above as
well as wing balance on the FD70 Flexdraper and Case 2162 headers. Please ensure all set-up,
as outlined in the operators manual has been completed prior to following the steps listed below.
Adapter Float (all headers):
1. Adjust header settings to match the following:
a. Lock wings into the rigid position (FD70 / 2162 only).
b. Set guard angle at mid position (B and ½ as indicated on the indicator mounted on the
combine adapter if equipped).
c. Set the reel in the mid fore-aft position (5 or 6 on the indicator).
d. Lower reel all the way to the cutter bar.
e. Store stabilizer wheels in the storage
position, off the ground (if equipped).
f. Raise header so cutter bar is 6-10” off the
ground.
g. Engage adapter float by placing handle in
the down position.
2. Set adapter float.
a. Tighten adapter float springs until washer
under down stop nut becomes loose. See
figure 1.
Note: It is recommended that you rock the header as
you adjust the float springs to reduce errors due to
friction.
b. Back off 2 full turns on each coil spring to
ensure header rests back on down stop.
Note: This setting is for cutting on the ground only. If
cutting off the ground, float may need to be set heavier
to avoid excessive bouncing and uneven stubble
height. Stabilizer wheels are also recommended when cutting off of the ground.
Wing Balance (for FD70 / 2162 only):
3. Set wing balance. See illustrations on next page.
a. Remove poly linkage cover.
b. Unlock wings by moving lever to unlock
position. If wing does not unlock use
wrench (stored in R/H leg) to apply torque
to bolt E (see illustration next page) to turn
the bell crank.
c. Move wing up and down by applying torque to bolt E (see illustration next page) to turn
the bell crank.
d. Adjust wing balance so that the wing can be moved into smile (up) or frown (down) with
approximately the same force.
i. If wing tend to smile (stay up), loosen clamp bolt F and turn draw bolt G
counterclockwise to move the clevis inboard
ii. If wing tends to frown (stay down), loosen clamp bolt F and turn draw bolt G
clockwise to move the clevis outboard.
