The purpose of this section is to define the proper methods for measuring
machine and implement offsets and dimensions for GreenStar setup in
any GS2 or GS3 display. Additional user guides can be obtained from
www.StellarSupport.com.
Measurement best practices:
• Measure while machine and implement are in a straight-line,
operating position.
• Implement dimensions may shift when in operation. Measure
implement when engaged with the ground to achieve the best
accuracy.
• Hold tape measure straight in vertical or horizontal directions.
Machine and implement Offsets are important for the system to
perform properly and accurately.
NOTE: Default setting for machine and implement offsets may not
account for unique setup and tolerances of equipment. Use a tape
measure to verify accuracy.

Machine Offsets
Row Crop Tractor
A or 1) Center of GPS Receiver to Center line of Machine
Applications requiring this setting include:
• Guidance
• Section Control
• Mapping & Documentation
Reasons for changing this setting to a value other than 0.0 include:
• A known GPS receiver offset from the center line of the machine.
• You experience an issue with AutoTrac accuracy between
passes. In this case, follow the steps below to measure the A offset.
Measuring Offset A:
NOTE: It is rare for this setting to be the cause of an AutoTrac accuracy
problem. Prior to adjusting this setting, check that the GPS receiver TCM
is calibrated properly, tires are inflated properly, and machine is ballasted
properly. Pass to pass accuracy problems are commonly caused by the
implement pulling to one side, which is covered in the implement sections
below.
1. Setup a Straight Track guidance line.
2. AutoTrac along the line, stopping at a few points to mark the
center of the machine (drawbar) with a flag.
NOTE: If the off-track error on the display is continuously off to one side,
this could be an indicator of a problem with the vehicle steering
components or calibration.

Measuring Offsets
3. Turn around and AutoTrac back over the same track in the
opposite direction, stopping at each flag.
4. Measure the distance between the center of the machine and
each flag. If this is a pass to pass issue, there should be a
relatively equal amount of difference between the flags
throughout the entire pass. If these measurements are within
the advertised accuracy of the system (SF1, SF2, RTK) then do
not change this offset and check the lateral implement offset
instead. Otherwise, divide that measurement in half to
determine Offset A.
NOTE: If the tractor needs to drive more to the right of its current path,
then toggle the offset direction on the display so that the GPS receiver is
shown to the right side of the center-line of the tractor image.
5. Repeat steps 2 through 4 to determine if the offset amount and
direction were set properly.

Implement Offsets
Implement Offset Descriptions
A or 1) In-line distance from the connection (pivot) point to the first
working point of the implement. Applications requiring this setting include:
• Mapping and Section Control – The sum of offsets A + B =
point where map recording happens and where sections are
turned ON/OFF. Offset A is also used for drawing the implement
icon to scale on maps.
• iTEC Pro – The implement may be raised and lowered at this
point during sequences.
Connection (Pivot) Point: Point where the implement connects to the
machine or the pivot point between implement and machine depending
on Connection Type. See Machine section above for close up views of the
Connection Point.
B or 2) In-line distance from the first working point to the second working
point, for example location of seed drop, spray nozzle, or cutter bar.
Applications requiring this setting include:
• Mapping and Section Control – The sum of offsets A + B =
point where map recording happens and where sections are
turned ON/OFF. Offset B is also used for drawing the implement
icon to scale on maps.
C or 3) Lateral distance from center line of the machine to center line of
the implement working width. Applications requiring this setting include:
