A control system for an agricultural system includes a first controller configured to receive sensor information from a plurality of sensors, in which the sensor information is indicative of a height of a header of the agricultural system, and the first controller is configured to convert the sensor information into position data. The control system further includes a second controller communicatively coupled to the first controller, in which the second controller is configured to receive the position data from the first controller, and the second controller is configured to determine a target position of the header based on the position data.

A lateral tilt control system for an agriculture harvester may include first and second tilt cylinders coupled between a support structure and an implement of the harvester. The first tilt cylinder may include a first cap-side chamber and a first rod-side chamber and the second tilt cylinder may include a second cap-side chamber and a second rod-side chamber. The system may also include a first fluid line providing a flow path between the first cap-side chamber and the second cap-side chamber and a second fluid line providing a flow path between the first rod-side chamber and the second cap-side chamber. Additionally, the system may include a pressure relief valve coupled between the first and second fluid lines to allow fluid to be transferred between the first and second fluid lines when a fluid pressure within either fluid line exceed a relief pressure setting.

A working vehicle includes a steering device to steer a vehicle body, a working device connected to the vehicle body, an automatic steering controller to perform automatic steering of the steering device based on a difference between a scheduled traveling line and a position of the vehicle body, and a parameter changer to change a control parameter of the automatic steering depending on the working device connected to the vehicle body.

An agricultural vehicle header having a center section, a wing section, a hinge connecting the center section's lower frame to the wing section's lower frame, and a torque transfer linkage connecting the center section's upper frame to the wing section's upper frame. The torque transfer link has a first link, a second link, a first pivot connection joining the first link to the center section upper frame, and providing a respective single degree of rotational freedom between the first link and the center section upper frame, a second pivot connection joining the first link to the second link, and providing a respective single degree of rotational freedom between the first link and the second link, and a third pivot connection joining the second link to the first wing section upper frame, and providing a respective single degree of rotational freedom between the second link and the first wing section frame.

A harvesting platform includes a first section and extends along a first section plane that is substantially parallel to a ground surface along which the harvesting platform moves with a combine. A second section is connected to the first side of the first section, and rotates with respect to the first section within a range of angular positions. A locking mechanism retains the second section in a position with respect to the first section while activated, and permits movement of the second section with respect to the first section while deactivated. A controller receives a first signal indicative of the position, and sends a second signal to deactivate the locking mechanism in response to the position being at a positive non-parallel angle with respect to the first section plane. The second section moves toward the first section plane in response to gravity while the locking mechanism is deactivated.

A working vehicle includes a steering handle, a vehicle body to travel with either manual steering by the steering handle or automatic steering of the steering handle based on a traveling reference line, an operator provided to the vehicle body, and a controller to terminate the automatic steering when the operator is operated under the automatic steering.
