AdjustmentsBelt Speed AdjustDraper Ground Engagement AngleDraper belt speed adjust allows the operator to increase ordecrease the belt speed.The HydraFlex Draper engagement angle is designed for optimumperformance on your combine. It is recommended that the factoryfeeder house fore/aft tilt frame setting be used. If adjustmentsare desired, refer to your combine Operator’s Manual for properinstructions.IMPORTANT: Excessive rearward tilt may result in frame assemblybeing pushed into the ground, causing material accumulation inthe float system components.Excessive forward tilt may result in the cutterbar pushing the crop.Hydraulic Feeder House Fore/Aft Tilt Adjust (If Equipped)Hydraulic feeder house fore/aft tilt adjust allows the operatorto increase or decrease the angle of the feeder house tilt frameenhancing the cutting performance.System Requirements:Engine is running.Road transport disconnectbutton must be disengaged.Multi-function leverreconfigurable buttons arefunctionally assigned andunlocked (B). 1. Press the Header application button and select the beltspeed section.2. To increase or decrease the belt speed, touch the plus ( )or minus (-) symbol or rotate the selection dial.3. Display shows the operator adjustment settings.Quick Side Belt Speed Reduction SwitchWhen crop is harvested on one side of the platform due toirregular shaped fields, slowing the side draper belts speedenhances the feeding performance.Side belt speed reduction switch allows the speedof the draper belt to automatically slow to a factorysetpoint speed.1. Press the side belt speed reduction button (A) on themulti-function lever.2. Slow Speed Mode Engaged appears on the display and the draperbelt speed automatically slows to the factory setpoint speed.3. Pressing the belt speed reduction switch again or attemptingto make manual belt speed adjustments while in slow speedmode automatically returns belt speed to the original speedset by the operator.B On-Screen1. To adjust the angle of the feeder house tilt frame touch plus ( )or minus (-) symbol or rotate the selection dial.Increase tilts feeder house tilt frame angle forward.Decrease tilts feeder house tilt frame angle rearward.2. Display shows operator adjustment settings. NOTE: If the original draper belt speed set by the operator isslower than the factory setpoint speed, the system will not engageand a diagnostic trouble code appears.See your John Deere dealer if the factory setpoint speed needsadjusted.Required Draper Belt Tension SettingMulti-Function LeverReconfigurable buttons (C) or(D) can be configured to controlhydraulic fore/aft.CAPush and hold front of switch(C) or (D) to tilt feeder houseforward.Push and hold back of switch(C) or (D) to tilt feeder houserearward.2DCritical: On the 730FD only,the idler belt tensioning boltshould be even with theoutside shield.Critical: Draper belt tensionindicator must be in theposition shown to ensureproper draper function inall conditions.3
Adjustments (continued)AHHC Mode OptionsReel Replacement/Reel Finger AdjustmentFor flex draper platforms, there are three unique Active HeaderHeight Control (AHHC) modes: On-Ground (“flex mode”) – soybeans, lentils, chickpeas Off-Ground (“rigid mode”), auxiliary attachment – wheat,barley, oats, canola On-Ground and Off-Ground AHHC are selected. AHHC resumeRecommended reel positionis directly over the cutterbar,and only low enough so thatthe lower portion of the reelfingers engage the crop(not the tube).button 2 is Off-Ground, AHHC resume button 3 is On-Ground(“hybrid mode”)Rule of Thumb: Out and Up!Reel finger pitch is adjustable. Adjustment levers areat both ends of the reel.A more advanced finger pitchhelps pick up downed crop.A less advanced pitchreduces the materialwrapping on the reel.Additional Recommended SettingsHeader Height/HydraFlex Pressure Control Knob With AHHC engaged, use the knob to adjust the headerset point.While operating in the flex mode,the knob adjusts the flex pressureset point.Higher pressure Less groundforce.While operating in rigid mode,the knob adjusts the height set point.Header Application ButtonFloat arm brackets may be reinstalledfor operating in off-ground modeafter the feeder house speedcalibration and header calibrationhas been completed.4BFor on-ground mode, lockout brackets(A) must be removed. Ensure that only the lockout bracketcross-bolt is removed when unlocking the float arms. The secondfloat arm stop bolt (B) is critical for function (Do Not Remove).When using off-ground mode with the ground-engaging sensorarms unpinned, ensure that grease has been added to the sensorarm pivot shaft and that the sensor arm rotates freely.Ensure that the storage pin is placedin the correct location.NOTE: It’s possible to use a Hybridmode where no calibration is neededwhen changing between on andoff-ground modes.Recommended Header Modes to EnableWith both On-Ground and Off-Ground sensing buttons turnedON, it’s possible to set the header activation button 2 on themulti-function lever. For the Off-Ground header height sensing andheader activation button 3 for On-Ground float pressure sensing.For pre-MY19 machines, refer to DTAC solution 92094 for enablinghybrid mode.Auto Header Control Press the Header application button, then select eitherthe manual HydraFlex float pressure adjustment or thebelt speed adjustment.AControl PreviewHeader AutomationDefaultsHeader activationbuttons 2 and 3 onthe multi-functionlever will activatethe platform.Pressing32Activates1CustomHeight ResumeONOFFHeight Sensing Off-GroudONOFFHeight Sensing On-GroundONOFFFeeder House FloatONOFFDial-a-SpeedONOFFFore/Aft ResumeONOFFReel Position ResumeONOFFCutterbar Position ResumeONOFFResume Preferences5

Calibration verifies that theAHHC sensors are set within the operating range. A failed calibration often means that a sensor is not set properly. See AHHCTroubleshooting and Sensor Voltage Map for more information. Broken sensor or components: Inspect sensors. Lock-out brackets still installed in the float arms. Off-ground sensor arm still pinned up. Off-ground sensor arm unable to fully rotate due to lack ofTuning calibration is also available after a header calibration isperformed. This tuning operation improves sensitivity of theHeight Sensing function and is recommended to be performedwhenever possible. AHHC TroubleshootingIf a header calibration fails, there are several common causesand solutions:Sensors seeing too much voltage range Float arm stop bolt was removed: Check the float arms forstop bolts.Sensor Voltage Settings Sensors may not be adjusted properly: See Sensor VoltageOperating range while harvesting of the AHHC sensor is 0.6 – 4.4 V.Sensor voltage readings can be viewed in LC1 Diagnostic Addresses –see the Calibrations section of the platform Operator’s Manual. It is highly recommended to set the sensors at 0.9 – 4.1 volts toensure that the sensor does not shift out of the operating range.Sensors out of range 6lubrication: Add grease to the fitting on the float arm.Damaged wiring harness: Inspect the wiring harness leadingto all the AHHC sensors.Settings.Damaged wiring harness: Inspect the wiring harness leadingto all the AHHC sensors.Broken sensor or components: Inspect sensors.If a header calibration fails, see the 700FD Sensor Voltage Mapto ensure that all sensors are set correctly.7
