Implement offset distance is used to enter the distance from the
centreline of the machine to the centre 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 offset distance
should be calculated and made to the implement offset distance value.
If using a self propelled sprayer or spreader, use the GPS 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.

GPS Offset Adjustment Calculation
To calculate a GPS offset adjustment using the same guideline:
1. Create a straight AB line.
2. With assisted/auto steering engaged, drive pass
 at least 100 feet / 30 meters and place flags at the draw bar or next to the machine.
3. Turn around and engage assisted/auto steering on pass  on the same AB guideline. Place flags at the draw bar or next to the machine,
or stop while on the AB guideline next to the flags you placed on pass  .
4. Measure the difference  between the flags of pass  and pass  .
5. Divide the measured distance  in half. This difference will be the offset adjustment.
6. Increase or decrease the offset distance as needed dependent on where the field application overlap occurs and the current implement
offset direction setting.
