Step 1) Tune Acquire Sensitivity
- Tune by operating parallel to and 1.2 m (4 ft.) from the A–B Line.
- Engage AutoTracTM Universal and observe performance.
- Tune Acquire Sensitivity until machine acquires line smoothly.
Step 2) Tune Line Sensitivities
A) Line Sensitivity – Tracking
- Tune Line Sensitivity – Tracking while operating on A–B Line.
- If machine wanders too far from the A–B Line, adjust Line Sensitivity – Tracking higher.
- If machine becomes unstable around A–B Line, adjust Line Sensitivity – Tracking lower.
B) Line Sensitivity – Heading
- Tune Line Sensitivity – Heading while operating on A–B Line.
- If front of machine wanders too far from track direction, adjust Line Sensitivity – Heading higher.
- If machine becomes unstable, adjust Line Sensitivity – Heading lower.
Line Sensitivities work together – If both are set too high, machine will become unstable. If both are set too low, machine will wander around A–B line. Operator may need to readjust Line Sensitivity – Heading and Line Sensitivity – Tracking for best results. Increase or decrease settings to change aggressiveness as desired.
Step 3) Tune Curve Sensitivity – if running Curve Track Advanced AutoTrac
- Tune Curve Sensitivity while operating in Curve Track.
- If machine turns outside of curve, adjust sensitivity higher.
- If machine turns inside of curve, adjust sensitivity lower.
Step 4) Tune Steer Play – system has excess play or on windrower
- Steer Play is only used for machines that have excess tolerance in the steering system.
- If overall performance is unacceptable due to high tolerance in steering system, adjust Steer Play setting higher until effects of loose steering system are minimized.
- If Steer Play is set too high, system will become unstable.
Step 5) Tune Steering Asymmetry
• Steering Asymmetry is only for machines that do not steer the same in each direction. • See platform specific document for your machine for the appropriate Steering Asymmetry value. • If machine is not asymmetric, use a value of 100.
Excessive wear on steering components may impact accuracy. Make sure steering system components have proper tolerances. Steer Play setting may improve performance on some machines, but cannot compensate for all wear. After installing AutoTracTM Universal Steering Kit, check steering system every 500 hours for proper tolerance and wear. Operator needs to tighten nut on steering wheel to manufacturer’s specified torque.
