Upper Cross Auger
The Upper Cross Auger (UCA) improves crop feeding into the center of the header in heavy crop conditions. It is ideal for
high-volume harvesting forages, oats, canola, mustard, and other tall, bushy, hard-to-convey crops.

Figure 3.260: Shutoff Valve
The shutoff valve (A) turns off the UCA when it is not needed.
NOTE:
Even though the UCA is shut off, it still needs to be greased at
the regular intervals because of the movement of the wings.
Adjusting Upper Cross Auger Position
The upper cross auger (UCA) has an adjustable mount that allows the auger position to be adjusted for different harvesting
conditions. Headers with three-piece augers have two adjustable mounts: one on each end of the center auger.
NOTE:
For information on the positions of the primary and secondary front bolts, refer to Figure

Figure 3.261: Initial Position of Adjustable Mounts
–
Two-Piece Auger
The mount(s) are initially installed in the rear-most position, so
that front bolt (A) is in the primary position. This is the
recommended configuration for most conditions.
When front bolt (A) is in the primary position, the auger and the
reel are safe to operate in any position. The position of the
auger can be adjusted (to a limited extent) by changing the
position of the mount with respect to rear bolt (B).
