Description of Automatic Header Height Control System

H98581
H98581-UN-14OCT10

A - Lateral Tilt

B - Header Height Sensing/Active Header Float

C - Header Height Resume

Automatic Header Height Control system compensates for uneven ground and controls horizontal and vertical positions of header. The system continuously compares the preset position and the actual position, thus keeping the header in the desired working position.

System Requirements:

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

Lateral Tilt Adjustment (A)

  • Parallel adjustments of the header in relation to the ground are carried out by sensors on each end of header. This ensures that the distance between the header and the ground is equal on both the left-hand and right-hand sides.

Platform Height Adjustment (B and C)

  • Header Height Resume — platform can be set to any position within the feeder house range.
  • Header Height Sensing — height of the platform is maintained with height sensors attached to the platform. This ensures that header height is always constant over rough terrain.
  • Active Header Float — machine maintains a constant header pressure with ground contact.
