An agricultural machine system includes: an agricultural work vehicle including a lift device; a header coupled with the lift device, the lift device configured for selectively moving the header between a plurality of positions associated with a header height including a low position, a high position, and an intermediate position therebetween such that the header occupies the intermediate position when the agricultural machine system is in a predetermined mode of operation.

A float cylinder and accumulator are coupled between a header main frame and an attachment frame. The float cylinder is orientated so that its mechanical advantage in applying a float force to the header varies with the position of the main frame relative to the attachment frame. Similarly, the pressure exerted by the cylinder varies inversely with its mechanical advantage.

A draper header includes a draper frame and a reel arm. The reel arm is coupled to a reel and pivotally coupled to the draper frame. The draper header further includes a cutterbar pivotally coupled to the draper frame. The reel arm and the cutterbar are configured to pivot about the draper frame to adjust a side profile aspect ratio of the draper header from a first aspect ratio to a second aspect ratio. A height of the first aspect ratio is less than a height of the second aspect ratio, and a width of the first aspect ratio is greater than a width of the second aspect ratio.

A system for infield collection of substantially whole cane and delivering that cane to a mill via a trash separator and a washer. A harvester collects whole cane and throws billeted cane along with trash into an infield transporter which then transports this to a centralised trash separator. The trash separator may service any number of infield transporters and may be located at a mill or a centralised location so that output from the trash separator may pass on to a conveyor. Billets are then fed to a washer. The washing liquid from downstream process may be used in the washer. Mud and dirt is removed from the billets in return liquid which then passes to a mud removal unit. This juice is returned to the downstream process. Wash liquid may also be collected via an outlet conveyor. A modular harvester, a trash separator and a washer are also described.

A header system for an agricultural harvester includes a first reel section, a second reel section, and a sensor configured to generate data indicative of a parameter related to a crop within a field. The header system also includes a controller configured to receive the data and to control a first actuator to adjust the first reel section independently from the second reel section based on the data as the agricultural harvester travels through the field.

An agricultural system includes a header and a controller. The controller is configured to receive a first input indicative of a set profile of the header, in which the set profile comprises a target position of the header for a non-harvesting mode, store the set profile of the header. The controller is further configured to receive a second input indicative of a selection of the non-harvesting mode, output a first signal to instruct the agricultural system to operate in the non-harvesting mode in response to receiving the second input, and output a second signal to set a current position of the header based on the set profile in response to receiving the second input.

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.

An agricultural system includes an arm configured to rotate about a pivot joint and to support a portion of a cutter bar assembly, a fluid-filled biasing member slidingly coupled to the arm, an actuator coupled to the fluid-filled biasing member, a fluid pressure sensor configured to measure a fluid pressure in the fluid-filled biasing member, and a controller communicatively coupled to the actuator. The controller is configured to receive an input signal from the fluid pressure sensor indicative of the fluid pressure and to output an output signal to instruct the actuator to adjust a connection point between the fluid-filled biasing member and the arm based on the input signal.

An agricultural system includes an arm of a header. The arm is configured to rotate about a pivot joint. The agricultural system also includes a fluid-filled biasing member, an actuator, and a controller. The fluid-filled biasing member is configured to couple to the arm and to impart a torque onto the arm. The actuator is coupled to the fluid-filled biasing member and is configured to move the fluid-filled biasing member relative to the actuator to change the torque imparted by the fluid-filled biasing member onto the arm. The controller configured to receive an input indicative of a target flotation pressure of the arm output a signal to instruct the actuator to set a position of the fluid-filled biasing member relative to the actuator based at least in part on the target flotation pressure of the arm.

An agricultural harvester, such as a combine harvester, which has an auxiliary axle assembly for support of the feeder house of the harvester. The auxiliary axle assembly can be provided in a retracted position when in a field mode, and can be locked in an extended position when in a road mode, where a wheel of the assembly contacts the ground. When in the locked, extended position, the auxiliary axle assembly supports substantially all of the weight of the feeder house and any attached implements, allowing the feeder house to pivot relative to the main chassis of the harvester.
