System and method for leveling a cutter bar of a harvester

A non-transitory computer readable medium comprising executable instructions that, when executed by a processor, are configured to cause the processor to:

• determine a target leveled base position of an arm of a header of an agricultural system, wherein the arm is coupled to a support of a fluid-filled biasing member of the header, the fluid-filled biasing member is configured to impart a torque onto the arm, the target leveled base position is indicative of a rotational position of the arm about a pivot joint, the target leveled base position is associated with a leveled configuration of a cutter bar assembly of the header, and the support of the fluid-filled biasing member is coupled to an actuator configured to move the support along the arm relative to the pivot joint;
• receive an input to set the cutter bar assembly of the header in the leveled configuration, wherein the cutter bar assembly is supported by the arm;
• and
• output a control signal to instruct the actuator to set the support relative to the pivot joint based on the target leveled base position in response to receiving the input to set the cutter bar assembly in the leveled configuration.

An agricultural system, comprising:

• a cutter bar assembly configured to cut crops during operation of the agricultural system;
• an arm assembly comprising:
• an arm configured to support a portion of the cutter bar assembly, wherein the arm is configured to rotate about a pivot joint;
• a fluid-filled biasing member comprising a support configured to couple to the arm, wherein the fluid-filled biasing member is configured to impart a torque onto the arm;
• and
• an actuator comprising a rod configured to couple to the support, wherein the actuator is configured to move the support along the arm relative to the pivot joint to change the torque imparted by the fluid-filled biasing member onto the arm;
• and
• a controller communicatively coupled to the arm assembly and configured to:
• determine a target leveled base position of the arm associated with a leveled configuration of the cutter bar assembly;
• determine the cutter bar assembly is to be set in the leveled configuration;
• and
• output a signal to instruct the actuator to set a position of the support relative to the pivot joint based on the target leveled base position in response to determining the cutter bar assembly is to be set in the leveled configuration.
