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