Fore/Aft
The fore/aft offset is the distance of the boom or implement in front or behind the GPS antenna. The fore/aft
offset must be measured perpendicular to the boom or implement width.
Note: The fore/aft offset must be measured perpendicular to the boom or implement width.
FIGURE 1. Example of the Fore/Aft Measurement
To set the fore/aft value:
1. Touch the current fore/aft value displayed on the Raven Offsets Setup screen.
2. Use the keypad to enter the measured fore/aft value in inches (U.S.) or centimeters (Metric) (see Figure 1
above).
3. If the boom or implement is in front of the GPS antenna, select the ‘Implement in Front’ option.
Left/Right
The left/right offset is the distance from the GPS antenna to the center line of the boom or implement.
Note: The left/right offset must be measured parallel to the boom or implement width.
