can also reduce cracks and splits in
corn, and improve distribution on the
cleaning shoe. Covers for this panel are
also available if needed.

Grates
*Ref. page 23
When installed in the front separator
grate section on the left and right side,
these will reduce rotor loss by giving
the corn an exit point. In drier
conditions, these grates can contribute
to shoe loss, due to the addition of
MOG on to the shoe.

The addition of large wire concaves will
improve threshing, reducing the
quantity of un-threshed pods in the
grain tank. Begin by ensuring the front
two on the right side are installed.
Tough conditions may require that all
12 concaves are large wire.

Concave Leveling and Indexing Adjustment
1. From inside the cab, adjust the concave clearance to the
smallest clearance achievable
2. Put the Rotor Gearbox in Neutral
3. Remove Concave sections #2 and #5 from the left hand
side of the cage, as shown in Fig. 1.
4. Rotating the rotor, determine which rasp bar is closest to
the bottom of the concave frame at sections #2 and #5.
5. Using a 1/2” Allen Wrench, or similar tool to gauge 1/2”,
determine if the gap between the bottom of the concave
frame and the two rasp bars found in step #4 measure
1/2”, as shown in Fig. 2, Measurement “A”.
6. If one or both measurements are incorrect, loosen the
stop bolts along the top of the concave frame, as shown
in Fig. 1, “A”.
7. Adjust the front and rear adjusting bolts inside the
springs (Fig. 3) accordingly until the rasp bars at con-
cave #2 and #5 both measure 1/2”. This will ensure that
the concave is level with the rotor, and that suggested
settings will be accurate.
8. Tighten the stop bolts at the top of the concave frame,
shown in Fig. 1.
9. Tension the front and rear springs to 5 5/16 in.(135mm),
as shown in Fig. 4, Measurement “A”.
10. In the cab, go to the Maintenance Menu, select
“Calibrations” and calibrate the concave.

Grain Loss Sensitivity
Nothing can replace the judgment of the producer when de-
termining an acceptable amount of grain loss from the com-
bine, however, the grain loss monitor in the combine can be
calibrated and adjusted to communicate to the operator
where grain loss is coming from and how significant it is. This
knowledge improves the efficiency of operation, and can
determine critical adjustments that must be made to improve
performance.
There are three loss sensors on the rear of the shoe and two
loss sensors on each side of the rotor, at the rear of the ma-
chine. The impact made by the grain lost and other crop de-
bris is shown on the bar graph at the top of the next page.
There are multiple factors that impact the suggested sensitiv-
ity. See a couple of examples below.
Corn - Rotor and Shoe loss sensitivity should be initially set
between 80% and 90% each.
Soybeans - Chopper Door Down (to include shoe discharge),
Rotor loss sensitivity should be initially set at 80%-90%, but
the shoe sensitivity should be set at 30%-40% due to the
increased MOG at the rear of the shoe.
The important piece to remember about the grain loss sys-
tem is that when the bar graphs move to show there is grain
loss, the operator understands how much loss is actually
exiting the combine, so that optimum ground speed and com-
bine settings can be achieved.
See pages 2-3 for Grain Loss Charts.

Automatic Header Height Control
1. Calibration - In order for Automatic Header Control to be
engaged, a successful calibration must be saved.
A. Navigate to the Maintenance Menu (Purple Hand)
and select “Calibrations”, then select “Header”.
B. Press in Fig. 1, and press the in Fig. 2 to
calibrate the header automatically, lowering
completely to the ground, raising all of the way up,
tilting left, tilting right, and centering itself. This
process takes a few minutes.
C. The minimum and maximum voltages for all of the
sensors on the combine and the header are saved
during the calibration sequence.
2. If one or more of the Header Calibrations is not
successful (red X), complete the following process to
adjust sensor voltages.
A. Level the header and set it firmly on to the ground in
the working position.
B. Navigate to the VMM3 Analog Inputs Screen, Fig. 3
C. Adjust each sensor on the left side of the header and
each sensor on the right side of the header to 1 volt
using the VMM screen as a reference.
D. Adjust the lateral tilt sensor to 2.5 volts using the
VMM screen as a reference.
E. Adjust the sensor for feeder house height to 1 volt
using the VMM screen as a reference.

Fieldstar
The C2100 shows Instantaneous and Average Yield
The yield shown is only valid after a proper calibration.
Press the “Play” button in the screen on the next
page to begin counting pounds that will be measured on
a grain cart with a scale, or from a scale ticket. A “Stop”
button will appear in its place
When the grain that will be weighed has been harvested,
press the “Stop” button
Take the known weight in Pounds and insert it in to the
white box that appears next to “Weighed” grain.
Accept the new calibration factor
Moisture is also shown on the C2100
Like yield, the moisture must be calibrated properly with
a trusted source in order to be used.
Example… If the moisture shown on the combine is
15%, but the Elevator records this grain at 18%, the user
must ADD 3 to the “Moisture Offset” shown on the next
page to complete calibration of the moisture sensor.
Alarms and Dry Yield Reference require an accurate
moisture calibration
