Header Height Sensing-HYDRAFLEX Platforms

HYDRAFLEX ™ system allows operator to select HYDRAFLEX pressure and works in conjunction with Header Height Sensing to maintain header position relative to ground, follow ground contour, and return to that position automatically.

Header Height Sensing system must be calibrated for each header that is used with the combine (See "CALIBRATION PROCEDURES" section).

Activation buttons 1, 2 and 3 located on the multi-function handle, are used for selecting three different HYDRAFLEX pressures.

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

Operation:

Header Height Sensing mode can be activated only when:

1. A properly equipped header is connected combine.
2. Engine is running.
3. Road transport disconnect switch is in field position.
4. Header height sensing mode is enabled.
5. Header engage switch is engaged.

Header Height Sensing system is enabled by pressing switch (A) on cornerpost display unit. Header Height Sensing symbol (B) will appear on display.

Activate Header Height Sensing system by pressing one of the activation buttons 1, 2 or 3 on the multi-function handle. Arrows (C) on each side of symbol indicate that system is active.

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

If you wish to change HYDRAFLEX pressure setpoint (E) of any activation button, press desired activation button and adjust pressure using Active Header Control dial (F) to change pressure setpoint. The change in the pressure setpoint will not change the height of the cutting platform.

Turning dial towards the (+) symbol will increase HYDRAFLEX pressure. Turning dial towards the (-) symbol will lower HYDRAFLEX pressure.

Bar graph (G) and number display (H) show HYDRAFLEX pressure.

Manually raising header height with switch (I) on multi-function handle will turn off Header Height Sensing function.

Pressing any activation button or manually lowering header with switch (I) will reactivate system. Header will return to selected pressure and Header Height Sensing will resume.

Header Height Sensing system can be disabled by pressing switch (A).
