How to Use Automatic Combine Adjustment on John Deere S700 Combines

Using the Automatic Combine Adjustment feature on your John Deere S700 Series combine makes optimizing harvest settings fast and easy. This guide walks you through how to use it, access presets, make custom adjustments, and ensure your combine is ready for any crop condition.

What Is Automatic Combine Adjustment?

Automatic Combine Adjustment lets you quickly apply preset harvest settings for common conditions (like dry or wet crops) on the Generation 4 display. This helps you save time, reduce grain loss, and adapt easily as conditions change.

Step-by-Step: Using Automatic Combine Adjustment

1. Access the Harvest Settings Page

• On your Generation 4 display, go to the Harvest Settings page.

• You can do this by:

  • Pressing the Harvest Setting shortcut icon on the shortcut bar.

  • Or, tapping the Harvest Settings icon on the run page.

2. Select a Preset Setting

• At the top, check which preset is currently active (e.g., “Dry Modified”).

• To change it:

  • Tap the preset and choose between available options (Dry, Wet, etc.).

  • After picking your desired preset (e.g., Dry), select it again so the correct settings populate in the new column.

3. Apply Settings Automatically

• Turn the separator on with your separator switch.

• Run the combine at high idle.

• Press the OK icon. The machine will automatically adjust to your chosen preset—the spinning circles indicate settings are being changed.

• Your core combine parameters (rotor speed, fan speed, concave clearance, etc.) are now set for the selected condition.

Adjust & Fine-Tune Settings

• Use the plus (+) and minus (-) buttons to make fine-tuned adjustments.

• The system updates to “modified” when you adjust from the preset defaults.

• If you experience tough threshing conditions, switch the Threshing Condition to “Difficult” to automatically tighten concave, increase rotor and fan speeds.

Resolving Issues

• If settings won’t apply (“new column” doesn’t light up), switch to another preset, then back and press OK again while the combine is running.

Save Custom Presets

• After tailoring your settings, save them as a custom preset for future use.

  • Go to the settings, name your preset (e.g., “Corn Test”), and save it.

  • This is handy for switching quickly between crops like soybeans and corn.

• To delete a custom preset, select it and tap the trash can icon.

• Note: Default dry/wet presets cannot be deleted.

Grain Loss Monitor Calibration

• The grain loss monitor updates automatically when using Combine Advisor and Auto Maintain—especially after setting a new performance target.

• To manually calibrate:

  1. Run the combine in crop.

  2. Tap Set to Current.

Returning to the Field

• Close out the Harvest Settings to return to the run page.

• Make small changes at any time using the shortcut buttons and thumb wheel dial on your armrest.
