Header Height Sensing-HYDRAFLEX™ Platforms

Header Height Sensing-HYDRAFLEX allows the operator to select the cutterbar ground pressure and return to that ground pressure 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. It uses sensors to measure the position of the header in relation to the ground.

Header Height Sensing-HYDRAFLEX must be calibrated each time that the header is used with the combine (see Calibration Procedures section).

Activation buttons 1, 2 or 3 located on the multifunction control handle are used to select one of three different programmed 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 then be assigned to Header Height Sensing.

Header Height Sensing-HYDRAFLEX will be active when:

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

The system is enabled by pressing button (A) on the display. Symbol (B) will appear on the display.

Activate Header Height Sensing-HYDRAFLEX by pressing activation buttons 1, 2 or 3 on the multifunction control handle. Arrows symbols (C) indicate that system is active.

Number (D) in the lower left corner of the display indicates which activation button was selected.

To change the HYDRAFLEX pressure setpoint (E) of the activation buttons, press the desired activation button and adjust the pressure using active header control dial (F). The change in the pressure setpoint will not change the height of the cutting platform.

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

Bar graph (G) and numeric display (H) show the relative position of HYDRAFLEX pressure.

Manually raising header height using header raise/lower switch (I) will deactivate the system.

Press any of the three activation buttons or manually lowering header height with header lower switch (I) will reactivate the system. Header will move to the selected pressure.

The system can be disabled by pressing button (A) on the display.
