Self-supporting harvester header system

A header of a harvester includes a first header segment comprising a cutter bar configured to cut crops, and a first portion of a conveyor assembly. The header additionally includes a center section including a second portion of the conveyor assembly. The center section is configured to receive cut crops from the first header segment via the first portion of the conveyor assembly. The header also includes a first ground engaging element configured to at least partially support a weight of the header, and a first sensor configured to output a signal indicative of a distance to ground. The header further includes a first actuator; and a control system comprising a processor configured to receive a sensor signal from the first sensor and to control the first actuator to adjust the first ground engaging element based on the sensor signal.
