Method for measuring combine header center of gravity and mass

An agricultural combine comprising:

• a chassis configured for movement on a surface;
• an intermediate member movably connected to the chassis;
• a first actuator connecting the chassis to the intermediate member and configured to move the intermediate member relative to the chassis;
• a first gauge configured to measure a first force generated by the first actuator;
• a header movably connected to the intermediate member;
• a second actuator connecting the header to the intermediate member and configured to move the header relative to the intermediate member;
• a second gauge configured to measure a second force generated by the second actuator;
• and
• a processing unit operatively connected to the first gauge and to the second gauge and comprising a processor and a memory, the memory storing computer readable instructions that, when executed by the processor, are configured to evaluate the first force and the second force to determine a position of a center of gravity of the header relative to the chassis.
