OPERATION
UPPER CROSS AUGER (Optional)
For tall or bulky crops, the optional upper cross
auger will aid crop flow across the header and
through the delivery opening.
The position of the upper cross auger is adjustable
for best feeding of the crop. Extremely tall crops
will require a higher setting.
To adjust vertical position:
15’ & 18’ Headers
• Lower reel fully.
• Remove bolts (A) at one end of auger and
reposition at desired location. Install the
extensions provided with the auger for
lowest settings.
• Repeat at other end. Be sure the same
position is used at both ends.
21’ & 25’ Headers
• Loosen two bolts (B) both sides.
• Adjust vertical position with drawbolt (C).
• Exposed thread on bolts (C) should be the
same both sides.
• Check that height is consistent across the
header and adjust as necessary.
• Tighten all hardware.
30’ & 36’ Headers
• Loosen two bolts (B) both sides.
• Adjust vertical position with drawbolt (C).
• Exposed thread on bolts (C) should be
equal.
• Loosen two bolts (D) at center bearing
support.
• Loosen jam nut on drawbolt (E) and adjust
vertical position of center support to align left
and right augers.
• Check that height is consistent across the
header and adjust as necessary.
