An agricultural header having a frame, a first support arm, a second support arm spaced from the first support arm, a reel extending from a first reel end rotatably mounted to the first support arm to a second reel end rotatably mounted to the second support arm, a first actuator operatively connected to the frame and the first support arm and configured to move the first support arm relative to the frame, a second actuator operatively connected to the frame and the second support arm and configured to move the second support arm relative to the frame, and a control system configured to alternately operate the first actuator and the second actuator in repeating alternating incremental steps to thereby move the reel from a first reel position relative to the frame to a second reel position relative to the frame. A combine having such a header is also provided.

A harvesting reel assembly for a header of an agricultural harvester is disclosed. The harvesting reel assembly includes a central rotatable shaft, a plurality of support members, a cam assembly and an extendable reel arm. The plurality of support members extend widthwise across the reel assembly and connect to the central rotatable shaft for rotation therewith. The cam assembly guides rotation of the plurality of support members. The extendable reel arm includes a first end engaged with the central rotatable shaft for rotation therewith. The extendable reel arm also includes a distal end opposite the first end connected to one of the plurality of support members.

A harvester is provided with a draper head that has a frame extending substantially across a working width of the draper head. Cutting elements are arranged at a front side of the draper head and connected to the frame. Conveying surfaces and conveying members transport cut crop from the cutting elements to a discharge location of the draper head. A reel extends transversely to a working direction of the draper head across the working width of the draper head. Reel support arms are pivotably supported on the frame and support the reel. A hydraulic adjusting drive is operatively connected to the reel support arms to pivot the reel support arms to carry out a height adjustment of the reel. A hydraulic circuit is operatively connected to the hydraulic adjusting drive and has a hydraulic valve that is able to lock the hydraulic circuit.

A system for automatic control of an operating parameter of a crop transport or processing device of an agricultural harvesting machine includes a sensor configured to detect at least one property of a crop or a parameter affected by the operating property and a control device disposed in communication with the sensor to receive signals therefrom. The control device is operable by means of the signals from the sensor using an algorithm to determine successive control signals for control of an actuator. The control signals affect the operating parameter of the crop transport or processing device that interacts with the sensed crop. An operator interface is included for input of corrective inputs for the operating parameter. The control device is connected to the interface and is operable to override the control signals sent to the actuator by means of the received corrective inputs.

A harvesting platform is connected to a combine for movement with the combine over the ground surface. The harvesting platform includes a cutter bar that cuts a crop being harvested, and a reel that presses the crop against the cutter bar during harvesting. The cutter bar moves between a cutter bar harvesting position and a cutter bar transport position, and the reel moves between a reel harvesting position and a reel transport position. A controller receives a first signal from a user via a user interface, sends a second signal to the cutter bar to move the cutter bar between the cutter bar harvesting position and the cutter bar transport position in response to the first signal, and send a third signal to the reel to move the reel between the reel harvesting position and the reel transport position in response to the first signal.

An agricultural harvesting machine has a cutting apparatus formed as a header for cutting and picking up crop of a crop stand, an inclined conveyor downstream of the cutting apparatus and in which a temporal layer height flow is adjusted, and a driver assistance system for controlling the cutting apparatus. The driver assistance system has a computing device and a sensor arrangement with a crop sensor system for generating crop parameters of the crop stand and a layer height sensor for generating the temporal layer height flow. The computing device simultaneously generates the cutting apparatus parameters of the cutting table length, horizontal reel position and vertical reel position so as to be adapted to one another and conveys them to the cutting apparatus to implement a harvesting process strategy in ongoing harvesting operation.

A rephasing system may include a first hydraulic cylinder, a second hydraulic cylinder, a first rephasing valve, a second rephasing valve and a controller. The first hydraulic cylinder and the second hydraulic cylinder include first and second pistons, respectively. A first hydraulic fluid line connects a hydraulic supply to a first side of the first piston while a second hydraulic fluid line connects a second side of the first piston to a first side of the second piston. The first rephasing valve fluidly couples the first side of the first piston to the first side of the second piston while the second hydraulic fluid line fluidly couples the second side of the second piston to the hydraulic supply. The controller selectively opens and closes the first and second rephasing valves to re-phase the first and second pistons.
