Allows operator to adjust cutterbar ground pressure, or cutterbar weight, and return to that setting automatically. HydraFlex works in conjunction with Header Height Sensing to maintain a header position relative to the ground, follow ground contour, and return to that position automatically. HydraFlex heads use a sensor located on the right side of the header to measure the hydraulic pressure used to support the cutterbar.

NOTE: HydraFlex does not control cutting height relative to ground. This is automatically controlled by the height sensing system and is not adjustable through the active header control dial when HydraFlex is present.

System must be calibrated with each header that is used (see Calibration Procedures section).

Activation buttons 1, 2 or 3 located on the multi-function lever are used to select one of the three different programmable HydraFlex pressures.

NOTE: If multiple modes are enabled, refer to Activation Button Mode Combinations in this section for further information.

Enable/Disable System:

Touch or press confirm switch when header setup icon is highlighted.

Touch or press confirm switch when automatic header height modes icon (A) is highlighted.

Touch or press confirm switch when Header Height Sensing icon (B) is highlighted.

NOTE: Checkmark appears indicating system is enabled or disappears indicating system is disabled.

• Properly equipped header is connected to machine.
• Engine is running.
• Road transport disconnect switch is in field position.
• Header Height Sensing system enabled.
• Header is engaged.

Activate Header Height Sensing (HydraFlex) by pressing activation buttons 1, 2 or 3 on multi-function lever.

Activation button number (B) on display indicates which activation button was selected.

Header Height Sensing icon (A) appears on display indicating system is active.

To change pressure setpoint (C) of activation buttons, press desired activation button and adjust pressure using active header height control dial (D).

Bar graph (E) and numeric display (F) show the pressure setpoint based on the pressure in the cutterbar on the platform.

NOTE: HydraFlex cannot operate independent of Header Height Sensing in an automatic mode. These systems work together to control cutterbar weight and header movement.

Turn active header height control dial towards plus (+) symbol to increase HydraFlex pressure and setpoint or towards minus (-) symbol to lower HydraFlex pressure and setpoint.

NOTE: Header lower switch can be set to immediately disable system until activation button is pressed, see your John Deere dealer for further information.

Manually adjusting header height with header lower switch (G) temporarily overrides system until released. Once switch is released, system returns to automatic mode.

NOTE: Header lower switch can be set to not reactivate system when header lower switch is pressed, see your John Deere dealer for further information.

Using header raise switch (G) temporarily deactivates system until header lower switch is pressed. Once switch is pressed, system reactivates.

Press activation buttons 1, 2 or 3 to reactivate system or manually lowering header height with header lower switch (G) reactivates system. Header automatically moves to preselected pressure.
