Harvest Smart Feed Rate Control—System and Field Symptoms

Machine is accelerating too slow:

• Increase response rate calibration, see Harvest Smart Feed Rate—System Adjustment in this section.

  Harvest Smart Feed Rate—System Adjustments

  • At higher response rates, machine will respond faster to changes. NOTE: Increasing response rate by increments of one is hardly noticeable. Increasing response rate by increments of 20 is more noticeable. After getting in an acceptable performance range, settings can be refined more closely.

    Increasing response rate has no effect on maximum deceleration.

    
    

Machine stops or over speed dramatically:

• If machine is at low end of threshing speed range and feed rate over speeds, increase rotor speed by 20 - 30 rpm. Recalibrate system, see Harvest Smart Feed Rate—System Adjustment in this section. NOTE: Calibration of Target Value is recommended again since rotor rpm was increased.

  Harvest Smart has limits detecting rotor load at the low and high end of threshing speed.

  
  

Ground speed oscillating:

NOTE: When harvesting new crops, it is normal for machine to oscillate for a short period of time.

• Decrease response rate.
• Machine is operating near maximum power (under 2200 rpm) and is causing machine to oscillate (speed up/slow down ground speed), see Harvest Smart Feed Rate—System Adjustment in this section.
  • Decrease response rate to stop oscillation and adjust target engine speed to control ground speed.

Ground speed oscillating in hilly conditions:

• As machine moves up hill it will keep a constant ground speed. If machine is moving up a steep hill, machine will slow slightly due to high hydrostatic forces, see Harvest Smart Feed Rate—System Adjustment in this section.
• As machine moves down hill it increases in speed, see Harvest Smart Feed Rate—System Adjustment in this section.
  • Operator should set a maximum harvest ground speed that is comfortable. This allows machine to not exceed maximum speed when going down a hill. NOTE: When harvesting in areas where crop conditions are tougher or along waterways and washouts, it is recommended that operator pull back on multifunction control handle. This gains control of machine and slows ground speed if operator feels machine is moving too fast.
    

Target or ground speed increases with no losses:

• When operating in Smart Mode, VisionTrak sensors are not working (matted over, disconnected, or are damaged), which causes machine to increase speed resulting in high losses, see Harvest Smart Feed Rate—System Adjustment in this section.
  • Change from operating in Smart Mode to Capacity Mode. This allows constant material flow, allowing machine to increase speed when crop materials are lighter and decrease speed when crop materials are heavier.

System loses target values:

• When operating in Smart Mode, system continuously recalculates target pressure values to adjust ground speed.
• Harvest Smart must be recalibrated each time key switch is cycled. System does not retain entry speed through key cycles.

Machine reacts too slow for crop changes:

• Machine response rate adjust is too slow, see Response Rate Calibration in previous section. NOTE: Increasing response rate by increments of one is hardly noticeable. Increasing response rate by increments of 20 is more noticeable.
  
  • Continue to increase response rate until oscillating occurs and lower response rate from that point.
  • High response rate settings will cause machine to make abrupt ground speed changes to maintain crop volume.
  • Low response rate settings will allow for less aggressive changes.

Machine reacts aggressively to crop losses:

• Capacity Mode allows constant material flow, allowing machine to increase speed when crop materials are lighter and decrease speed when crop materials are heavier.
  • Recalibrate VisionTrak, see Harvest Smart Feed Rate—Initial Calibration in this section.
  • If recalibrating VisionTrak has no affect, switch to Capacity Mode, see Harvest Smart Feed Rate—System Adjustment in this section.
  • In some conditions, Capacity Mode is a better mode for operation.
