Active Implement Guidance – Set Up

This section provides guidelines for setting up the Active Implement Guidance system.

Start-Up Settings Guidelines

Select the SCV Control Type for the implement steering mechanism. Options include Off, Implement Steering, or Implement Shifting. If using an external valve, select SCV1 or SCV3 to match the angle sensor connector label.

Control Selection

• SCV Control Type: Implement Steering
• SCV3 Control Type: Off

[Back]

Tune SCV Threshold

Note: SCV Threshold Setup is not used for external valves. Refer to External Valve Setup.

Set Wheel Angle Sensitivity

This is a coarse adjustment to indicate the size of the steering cylinder. A smaller number indicates less hydraulic flow for the cylinder. Recommended settings are starting points; fine-tuning may be required.

• Small Cylinder = 500
• Large Cylinder = 5000

Adjust SCV Flow

Note: SCV Threshold Setup not used for external valves. See External Valve Setup.

Select SCV and turn the flow knob on the tractor's right-hand display (RHD) to adjust (Range 0.1 to 10). Turn SCV flow up until the steer mechanism is unstable or banging. Back flow off until the mechanism stabilizes.

External Valve Setup

This adjustment replaces the SCV Flow adjustment for external valves. Set SCV1 or SCV3 Max Flow (%) to achieve desired manual control. Small cylinders may require a low value.

Calibration Guidelines

Calibrate wheel angle sensor voltage:

• Manually move the steered implement to the right limit and select SET MAX RIGHT POSITION.
• Manually move the steered implement to the left limit and select SET MAX LEFT POSITION.
• Manually move the steered implement to the center position and select SET CENTER POSITION.

Voltages should vary equally above and below the center voltage. Ensure the center position is properly calibrated for accurate line tracking.

Recommended Starting Settings

These settings are a starting point for most vehicles. Adjustments can optimize performance. SCV flow may need adjustment.

Implement Receiver Setup

Implement receiver TCM must be turned ON and calibrated for Active Implement Guidance. Use the implement axle as the calibration point. Enter height and fore/aft settings on the Implement Receiver's StarFire page. Set fore/aft to zero and measure height from the ground to the StarFire's yellow dome.

Implement Receiver Lateral Offset

If the implement receiver is not centered, enter a Lateral Offset to account for the shifted location.

Operating Guidelines

Setup guidance lines on the GreenStar Display and turn Steer ON.

Detent SCV forward: Should transition from "EC" to "AC" or "AUTO" to "AUTO" on RHD.

*30 Series and older (00/10/20/30 Series)

Press AT resume switch to engage the system. The machine and implement should steer to the line. NOTE: AutoTrac in reverse will disengage after 45 seconds.

Follow Mode

Follow Mode sets the implement guidance path to match the machine receiver's path. This allows Active Implement Guidance to operate without a defined guidance line, with the operator driving the machine. This is useful for the first pass through a field when the guidance line is being defined.

Sensitivity Adjustments

Line Sensitivity Tracking

Range: 10 to 10000. Typically 1500 to 5000. This setting affects performance while acquiring the track.

Line Sensitivity Accumulated

Range: 10 to 1000. Typically 150 to 500. This setting affects performance while on track.

Optimizing Active Implement Guidance Performance

Step 1 - Tune tractor SCV flow or External Valve Max Flow: Turn SCV flow up until the steer mechanism is unstable or banging. Back flow off until stable. For external valves, adjust Max Flow (%) for desired manual control.

Step 2 - Tune Line Sensitivity Tracking: Determines how aggressively the vehicle acquires the track. Affects performance during track acquisition.

Sensitivity too High | Sensitivity too Low

Step 3 - Tune Line Sensitivity Accumulated: Determines how aggressively the system responds to tracking errors while on track. Affects performance while on track.

Sensitivity too Low | Sensitivity too High

Sensitivity too Low on steep slopes when implement doesn't track on line.
