How to Use Controlled Traffic Mode in John Deere Machine Sync

Controlled Traffic Mode in John Deere Machine Sync offers operators a way to enhance efficiency and reduce field compaction by guiding support machines, like grain carts, along fixed paths (A-B lines) rather than directly following the combine’s movements. This article explains what controlled traffic mode is, when to use it, and what benefits it brings to your field operation.

What Is Controlled Traffic Mode?

Controlled Traffic Mode is a selectable feature within John Deere’s Machine Sync system. When enabled, it allows the tractor and grain cart to follow a fixed A-B guidance line for travel across the field, instead of constantly adjusting to mirror the combine’s every move.

How to Enable and Use Controlled Traffic Mode

1. Access Machine Sync Advanced Settings

   • Navigate to the Machine Sync menu and open Advanced Settings.

2. Toggle Controlled Traffic Mode

   • Choose whether to turn Controlled Traffic Mode ON or OFF.

   • When ON, the grain cart follows a selected A-B line for the field.

   • When OFF, the grain cart’s path is based on the combine’s position.

3. Select the Right Guidance Line

   • Pick the proper A-B line for your field.

   • Use the Shift Track or Center Track buttons to fine-tune the cart’s position relative to the combine.

4. Follow and Adjust as Needed

   • Press resume to activate. The tractor follows the guidance line and auto-matches speed to the combine.

   • To shift the cart’s position slightly, use the Shift Track buttons—each press adjusts the line by 1.5in.

   • When changing directions across the field (e.g., from north to south), you may need to re-center or reposition the A-B line beneath the combine.

Benefits of Controlled Traffic Mode

• Smoother Operation
  Running on an A-B line avoids the constant side-to-side corrections required when following the combine directly. This results in a smoother ride and better wheel tracking.

• Consistency During Disengagement
  If Machine Sync disengages for any reason, the tractor will continue to follow the established A-B line, helping prevent unintentional deviations in the field.

• Reduced Compaction and Overlap
  By keeping machines on set traffic lanes, field compaction is minimized and overlap is reduced—great for long-term soil health and efficiency.

When Not to Use Controlled Traffic Mode

• Curved Passes and End Rows
  If the field has notable curves or requires following a meandering edge (such as along a creek), disabling controlled traffic mode enables the cart to better mimic the combine’s changing path.

• Dumping in Multiple Directions
  When dumping on both north-south passes or frequently changing direction, standard mode (controlled traffic OFF) may be simpler, as there’s no need to reset your A-B line each time.

Example: Dumping Going Both Directions

If you’re shelling corn and dumping both north and south, the A-B line’s relationship to the combine will flip. You’ll need to re-center or shift the line each time you switch direction by driving under the auger and hitting the Center Track button.

Key Takeaways

• Use Controlled Traffic Mode for straight passes, smoother operation, and reduced compaction when you’ll be driving consistent, parallel lines.

• Turn it off for curved areas or complex field shapes, or if you need position flexibility without resetting your guidance line frequently.

• Adjust position easily with Shift Track or Center Track as needed.
