UNLOADING & ASSEMBLY
974 FLEX HEADER: WING FLOAT SET-UP AND PRE-DELIVERY CHECK
1. Set the combine adapter float components, skid plate and tine drum to suit the flex header and your
combine model. See “Preparing the Adapter” in the Assembly section of the Adapter Operator’s Manual.
2. Install adapter in header. Leave the adapter spring float lockout engaged. See Adapter Operator’s Manual.
IMPORTANT:
For units with gauge wheels, pin the gauge wheels up off the ground so their flotation effect
does not interfere with the wing float setting.
3. Ensure wing float lock pins (2 per side) are in
engaged position (A) as shown. Pins are spring
loaded to the engaged position.
If pins are disengaged:
•
Rotate pin handles to release the roll pins
from the notch.
•
Lower cutterbar onto two 6” (150 mm) blocks
at dividers until inner pins snap into engaged
position.
•
Remove blocks and place them just inboard
of cutterbar flex points
•
Lower header onto blocks until outer pins
snap into place.
4. Pick up header with combine and raise cutterbar
approximately 6” (150 mm) off ground. (Remove
blocks if they were required for Step 3.)
5. The smile/frown, fore-aft straightness and vertical
alignment of the wing frames is controlled at the
factory. Adjustment should not be required.
Procedures for checking and adjustment are
included in the Header Technical Manual.
6. Set top link to a mid-range header angle position
(approximately 490 mm [19-1/4”] pin to pin).
7. Disengage adapter float spring lockout, both
sides. Ensure gap at (C) is 1/2” (13 mm) with
cutterbar 6” (150 mm) off ground.
NOTE:
Notch (D) is provided as an alignment
mark for this setting, as shown.
See Adapter Operator’s Manual. Wing float lock pins remain engaged, as above.
