4.5.3 Header System Calibration
The Harvest Performance Tracker (HPT) recognizes when a header is attached to the windrower and determines which
systems will require calibration.
The following sensors may require calibration, depending on the type of header attached to the windrower:
• Header height
• Header angle
• Header float left
• Header float right
• Reel height
• Reel fore-aft
• Swath compressor
• Knife drive
Recalibration is required in the following circumstances:
• The HPT is replaced
• A position sensor is replaced
• Sensor readouts are erratic
• A pump has been replaced
• A new header type or attachment is connected to the windrower
Refer to following topics for information on calibrating header systems:
• Calibrating Knife Drive on Harvest Performance Tracker Display, page 182
• Calibrating Header Position Sensors on Harvest Performance Tracker Display, page 185
Calibrating Knife Drive on Harvest Performance Tracker Display
When a header is attached to a windrower, the Harvest Performance Tracker (HPT) will recognize the header ID and
configure the windrower accordingly. The header must be calibrated to ensure that the knife drive pump output is
accurate.
