The Overlap parameter is used so that there is an overlapping area between each of the navigation guides, intentionally by the user. One of the most common examples of its use is in spraying, so that the overlap compensates for possible application failures due to drift of the spray by the wind.
The overlap value is measured in centimeters, on the same line as the implement bar, transversely in relation to the tractor axis.
Considering a 30-meter wide implement, 2 examples of the use of the Overlap parameter are presented.
Example 1 – Overlap = 0 cm
In the case where there is no overlap, the distance between the navigation guides is equal to the width of the Implement, as shown in the following image.
Example 2 – Overlap = 20 cm
When the overlap is greater than zero, the distance between the guides will be the difference between the width of the Implement 
and the value set to Overlap 
. In the example: (30.0 m – 0.2 m) = 29.8 m 
. The figure below illustrates the effect of the overlap in the trail on the parallel guides.
The configuration screen for the Overlay parameter is shown in the image below, including the self-explanatory figure of its meaning.
