In a crop harvesting header with a center section and two wings where each wing is pivotal relative to the center section about a pivot axis extending in a generally forward direction which includes a balance system to maintain a balanced ground force distribution across the width of the header there is provided an automatic adjustment system for maintaining proper balance. The system includes a sensor which repeatedly, over a time period during which the header is operating, detects data relating to the positions, distance from the ground or weight applied to the ground of each wing frame portion, a processor arranged in response to the sensed data to calculate a value representative of the positions and an adjustment mechanism for effecting an adjustment of the balance system in response to the value.
