Abstract
A method for dynamically operating a header float system of an agricultural vehicle having a header movably mounted to a frame by an actuator and a flotation adjustment system that relies on ground-contact force measurement. The method includes: determining an initial zero value load sensor output signal representative of an initial position of the header raised out of contact with the ground surface, calibrating the sensor with the initial zero value, operating the header to process a crop material, detecting a subsequent position of the header out of contact with the ground surface, determining a subsequent zero value representative of the subsequent position of the header, and re-calibrating the sensor with the subsequent zero value. Also, an agricultural vehicle having a header operated as described above.
