In straight mode, the Outback S generates perfectly straight, parallel lines based on the first A - B pass. It then records in memory the actual movement over those lines as you guide. In contour mode, all movement is recorded as the machine moves around. During the first pass, no guidance is given. When the operator attempts to make a second pass, the Outback S begins to guide along the previous pass.
All movement is recorded in memory .
The operator can switch back and forth between Straight and Contour . Since contour guidance follows other passes, it will attempt to follow any pass that was recorded in the current job no matter if that pass was done in straight or contour mode. This is very easy. Usually headlands are performed in contour mode. Make one pass and then use the guide on the second pass.
