The Harvest Smart system is an adaptive, on-the-go control system designed to enable automatic ground speed control during harvest operation. Harvest Smart ensures the combine maintains a consistent crop load (feedrate) by automatically changing the combine ground speed to compensate for variations in crop that are not readily visible to the operator.
During the course of a long harvest day, operators are challenged to maintain the combine at peak performance due to varying crop conditions that affect the crop load entering the combine. The Harvest Smart system will adjust to changing conditions faster than an average operator, maintaining a consistent crop load into the combine. Since the Harvest Smart control system automatically keeps the machine at maximum load capacity, as set by the operator, fatigue and stress are reduced and overall harvesting productivity is increased.
- Keeps a consistent crop load in the separator (rotor) for better utilization of machine capacity
- Maintains a consistent combine loss level for reduced overall field losses
- Reduces operator fatigue and stress during long harvest days
- Maintains consistent grain quality and cleaner grain sample due to more consistent crop loads in the combine
Theory of Operation:
The Harvest Smart system uses three main inputs from the combine to automatically adjust the ground speed of the combine. The system uses information on:
- Crop load in the separator (rotor)
- Grain loss from the VisionTrak™ monitor
- Engine load
Smart mode (rotor pressure and grain loss monitor):
Smart mode monitors rotor pressure and loss level while maintaining operator established parameters (loss monitors must be calibrated). While harvesting with machine optimized at the operators acceptable loss level, the system is set when the calibration button on the grain loss screen is pressed. When loss monitor levels are consistently above or below operator desired levels, system increases or decreases material flow levels, bringing loss levels back into desired range. Smart mode is not an immediate or instant adjustment; the system will change ground speed while not exceeding the parameters established by the operator.
Capacity mode (rotor pressure):
Capacity mode maintains a constant material flow, allowing the machine to increase ground speed when crop materials are lighter and decrease ground speed when crop material is heavier. Capacity mode does not monitor the grain loss system since the mode is only maintaining a constant material flow.
NOTE: Capacity mode should only be used when loss monitors are not reliable, such as when sensors are matting over with crop.
