IMPLEMENT LATERAL OFFSET DISTANCE ADJUSTMENT

Implement lateral offset distance is used to enter the distance from
the centerline of the machine to the center of the implement. When
on-screen mapping shows no overlap or gap, yet field application
produces an overlap or gap consistently to only one side in the
direction of travel, an adjustment to the implement lateral offset
distance should be calculated and made to the implement offset
distance value.
If using a self-propelled sprayer or spreader, use the GNSS Offset
Adjustment Calculation to calculate the implement offset distance
adjustment.
If using a pull behind or trailed implement, use the Implement Offset
Adjustment Calculation to calculate the implement offset distance
adjustment.
NOTE: While using assisted/auto steering, if on-screen mapping
shows overlaps and gaps, adjustments may need to be
made to the assisted/auto steering settings.

GNSS Offset Adjustment Calculation

To calculate a GNSS offset adjustment using the same guideline:
1. Create a straight AB line.
2. With assisted/auto steering engaged, drive pass
3. Turn around and engage assisted/auto steering on pass
or stop while on the AB guideline next to the flags you placed on pass

4. Measure the difference
5. Divide the measured distance
6. Increase or decrease the offset distance by the offset adjustment value determined in Step 5, and repeat the test. The lateral antenna
offset distance has been adjusted correctly when the vehicle's wheel tracks are in the same location driving in both directions. If this
adjustment results in the lateral antenna offset distance being adjusted by more that 4 in / 10 cm, the Automatic Calibration should be
redone.
