    S Series Combines

    A - Float Pressure Adjust Switch

    B - Selection Dial

    Platform must be attached to combine. Each sensor is checked separately.

    NOTE: Verify optional auxiliary header height sensors (if equipped) are secured in storage position. See Automatic Header Height Control — Rigid Mode in Operating The Platform section in Operators Manual.

    Attach platform to combine (see combine Operators Manual for attachment information).


  2. Increase platform float pressure to maximum:

    1. Press float pressure adjust switch (A) on armrest.

    2. Rotate selection dial (B) clockwise (+) to increase cutterbar pressure. Setting will be displayed on armrest display screen.

    3. Completely lower header to ground.

  3. Shut OFF engine and set parking brake.

    A - Header Height Sensor Voltage Reading

    B - Auxiliary Header Height Sensor Voltage Reading (If Equipped)

    C - Return/Back Arrow Icon

    Operating voltage range of sensors must fall between 051—449.

    Right most numbers (last three) are used to indicate header height sensor voltage.

    Recommended voltage range of header height sensors should fall between 070—430.

    Left most numbers (first three) are used to indicate the optional auxiliary header height sensor voltage.

    Recommended voltage range of optional auxiliary header height sensors should fall between 060—440.

    Sensor Voltage Readings:

    1. Header height sensor voltage reading (A) with float system at upper limit should fall between optimal range of 070—130.

    2. Optional auxiliary header height sensor voltage reading (B) with optional auxiliary header height sensors in storage position should fall between optimal range of 060—100.

    NOTE: If no number is present or voltage readings do not fall between 051—449, then header height sensors on platform will not function properly and will need adjusted (See Adjusting Header Height Sensors section in this manual).


  13. Touch or press confirm switch when return/back icon (C) is highlighted to return to previous screen.

  14. Repeat sensor voltage adjustment for each address at maximum float pressure.

    A - Feeder House Safety Stop

    Death to you or others can result from feeder house inadvertently lowering. Completely raise feeder house and verify that safety stop is engaged when performing this procedure with header attached.

    NOTE: Verify optional auxiliary header height sensors (if equipped) are unpinned and fully lowered. See Automatic Header Height Control — Rigid Mode in Operating The Platform section in Operators Manual.

    Completely raise feeder house and engage safety stop (A).

    Decrease platform float pressure to minimum:

    1. Press float pressure adjust switch (A) on armrest.

    2. Rotate selection dial (B) counter clockwise (-) to decrease cutterbar pressure. Setting will be displayed on armrest display screen.


  17. Shut OFF engine and set parking brake.

  18. Repeat steps 4—11 to check sensors at minimum platform float pressure.
