Ground pressure feedback sensor system for controlling header float

An agricultural vehicle comprising:

• a chassis enabling movement across a surface;
• a frame movably mounted to the chassis;
• a skid shoe movably mounted to the frame between an extended position and a retracted position;
• an actuator operatively connected between the frame and the chassis and configured to moves the frame relative to the chassis;
• a load sensor assembly operatively connected between the frame and the skid shoe, the load sensor assembly comprising a load sensor operatively connected between the frame and the skid shoe under a preload force that biases the skid shoe towards the extended position;
• and
• a control system operatively connected to the load sensor and the actuator, and operates the actuator in response to a signal from the load sensor;
• wherein the frame comprises:
• a header main frame being movably attached to the chassis by the actuator;
• a header subframe being movably connected to a header main frame and the chassis by the actuator;
• or
• a header wing section frame being movably attached to a header center section frame and the chassis by the actuator.
