Flag offset method for roll offset
1. Remove any implement from the vehicle. The vehicle draw-bar must be centered.
2. Drive the vehicle to a relatively flat area where you can complete passes that are at least 400 m
(1320 ft) in length.
3. Reset the Roll Offset value to 0 (zero) on the Roll Correction screen. See Roll / antenna
compensation calibration (page 181).
4. Create an AB Line.
5. Start a new pass. Engage automatic steering mode when the system is stable. Stop the tractor
midway through the pass. Confirm that there is no cross track error: the current vehicle
position should be directly on the AB Line.
6.
Park the vehicle and exit the cab. Use the hitch pin hole in the drawbar as a guide to insert a flag
in the ground to mark the vehicle center-line for this pass.
7. Complete the pass. Turn the vehicle around to return along the same pass from the opposite
direction.
8. Engage automatic steering mode. Stop the vehicle midway down the pass with the drawbar pin
location very close to the marker flag. Confirm that there is no cross track error: the current
vehicle position should be directly on the AB Line.
