Automatic Header Height Control System

Automatic Header Height Control system compensates for uneven ground and controls horizontal and vertical positions of the header. The system continuously compares the preset position and the actual position, thus keeping the header in the desired working position. Enter values using the response rate adjust, sensitivity adjust, and the selection dial on the armrest.

System Requirements:

  • Road transport disconnect switch must be in field position.
  • Engine is running.
  • Header engaged.
  • Desired header control mode activated.

Lateral Tilt Adjustment-Two modes

  • Manual Adjust - activate hydraulic components with the multifunction control handle.
  • Automatic Adjust - parallel adjustments of the header in relation to the ground are carried out by sensors on each end of header. These adjustments ensure that the distance between the header and the ground is equal on both the left-hand and right-hand sides.

Platform Height Adjustment-Four Modes

  • Manual Adjust - activate hydraulic components with the multifunction control handle.
  • Automatic height resume - platform can be set to any position within the feeder house range.
  • Automatic height sensing - height of the platform is maintained with height sensors attached to the platform. This setting ensures that header height is always constant over rough terrain.
  • Automatic float control - machine maintains a constant header pressure with ground contact.
