Tuning Slope Compensation
Slope Compensation works as a lookahead for the
vehicle. Slope Compensation helps aids in moving the
vehicle up the hill to keep the implement on the guidance
line.
Slope Range
Typical Value
Degree
Cm/Degree Inches/Degree
0—2 1.3 0.5
2—5 1.3—3.8 0.5—1.5
Greater Than 5
2.0—8.9 0.8—3.5
0—2 degrees  Slope Compensation may not be needed
2—5 degrees Use of Slope Compensation is
recommended to provide moderate amount of machine
correction
Greater than 5 degrees Use of Slope Compensation is
recommended
NOTE: If slope compensation value is above 4.00
after calibration, calibrate again. Recalibration
is recommended to verify a consistent slope
compensation value. If a consistent value is not
achieved, review the slope compensation guidelines.
General Slope Compensation Guidelines:
1. iGuide must be active to calibrate
2. Calibrate at operating speed with implement at
operating depth

3. Do not calibrate when:
Roll angle is less than 2 degrees
Direction of roll angle may change
On tight curves
A line acquisition is occurring
4. Slope compensation may not be required on slopes
less than 5 degrees
5. Stop calibration after calibrated slope compensation
value stabilizes
Tuning iGuide Sensitivity
Tuning iGuide Sensitivity properly will ensure the system
responds quickly to line and heading acquisition.
iGuide Sensitivity works in a similar way as the AutoTrac
Sensitivity and will be different according to the soil
conditions, machine, and implement models. iGuide
Sensitivity is lower when soil condition is harder and is
higher when soil condition is softer.
Adjust AutoTrac Steering sensitivity for the vehicle.
Verify Implement Guidance Mode is set to “None”
Refer to GreenStar Display Operator’s Manual for
process of tuning steering sensitivity

C—Increase iGuide Sensitivity
NOTE: For some platforms, such as four wheel drive
tractors, use a higher AutoTrac Sensitivity
for best performance.
