Header Height Sensing—HydraFlex Platforms

A - Header Height Sensing Button

Header Height Sensing—HydraFlex allows the operator to adjust cutterbar ground pressure, or cutterbar weight, and return to that position automatically. HydraFlex works in conjunction with Header Height Sensing to maintain a header position relative to the ground, follow the 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 the 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 with the machine (see Calibration Procedures section).

Activation buttons 1, 2 or 3 located on the multifunction control handle are used to select one of the three different programmable HydraFlex pressures.

NOTE: If both Header Height Resume and Header Height Sensing are enabled, only activation button 1 will activate Header Height Resume, activation buttons 2 and 3 will be assigned to Header Height Sensing.


Operation:

System is active when:

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

D - HydraFlex Active Symbol

E - Numeric Display

F - Activation Button Number

G - Pressure Setpoint

H - Header Height Control Dial

I - Bar Graph

J - Header Raise/Lower Switch

Press Header Height Sensing button (A) on display to enable system. Symbol (B) will appear.

Activate Header Height Sensing—HydraFlex by pressing activation buttons 1, 2 or 3 on multifunction control handle. System activation arrows (C) will appear indicating system is activated. Weight symbol (D) and numeric display (E) will appear indicating HydraFlex pressure is being monitored during header height sensing.

Activation button number (F) in lower left corner of display indicates which activation button was selected.

To change pressure setpoint (G) of activation buttons, press desired activation button and adjust pressure using active header height control dial (H). Pressure setpoint is displayed by an arrow to the left of the bar graph and actual pressure is shown in numeric display (E). Bar graph (I) shows whether the pressure matches the setpoint indicator.

NOTE: HydraFlex can not 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

Manually adjusting header height using header lower switch (J) will temporarily override system until released. Once switch is released, system will return to automatic mode. Using header raise switch (J) will temporarily deactivate system until header lower switch is pressed. Once switch is pressed, system will reactivate.

Press activation buttons 1, 2 or 3 to reactivate system or manually lowering header height with header lower switch (J) will reactivate system. Header will automatically move to the preselected pressure.

System is disabled by pressing button (A).
