A harvesting system for harvesting stalky plants is mountable on a power unit such as an agricultural combine. The harvesting system may have both an upper harvesting head that cuts off the tops of the plants and the directs seed-bearing portions of the plant to the combine's thresher, and a lower harvesting head cuts the stalks near the ground and discharges the stalks in two or more windrows. In order to increase throughput, the upper harvesting head may be raisable and lowerable relative to the combine's feeder housing. To accommodate such adjustment, a discharge conveyor of the upper harvesting head may extend at an adjustable angle relative to the feeder housing. The lower harvesting head may have draper belts arranged to discharge the stalks in two or more, and more typically three or more, laterally spaced, parallel windrows.

A work machine includes a chassis, and a work implement movably coupled to the chassis and configured to perform a field-engaging function. The work machine also includes an actuator coupled to the work implement and configured to adjust a position of the work implement relative to a ground surface. The work machine further includes a sensor unit configured to sense a characteristic of the work machine and communicate a signal indicative of the characteristic. The work machine also includes a communication module, and a controller in communication with the sensor unit and the communication module, the controller including a processor and memory. The controller is configured to monitor a location of the work machine, process the signal from the sensor unit to monitor the characteristic, determine whether the characteristic exceeds an acceptable range, and if so, identify an event, and assign a location to the event.

A support system for an agricultural header includes a first actuator configured to couple to a frame of the agricultural header and to a first element of the agricultural header. The support system also includes a second actuator configured to couple to the frame of the agricultural header and to a second element of the agricultural header. Furthermore, the support system includes a third actuator configured to couple to the frame of the agricultural header and to the second element of the agricultural header. The support system also includes a fluid supply system configured to provide pressurized fluid to the first actuator and to the second actuator. The third actuator is fluidly isolated from the fluid supply system, the first actuator, and the second actuator.

A combination flex and rigid control system for a header of an agricultural harvester includes ground proximity detection arrangements for both rigid mode and flex mode operation of the header. The ground proximity detection arrangements are each coupled to the same sensor shaft by way of a sensor arm that is moved by either of the ground proximity detection arrangements.

An agricultural harvester is disclosed. The agricultural harvester comprises a header. The header includes a frame, a control shaft connected to the frame, a flex arm, a linkage assembly and a cutter bar connected to the flex arm. The linkage assembly is movable between a first position and a second position. The linkage assembly includes a first end pivotably connected to the control shaft and a second end connected to the flex arm.

A hydraulically driven tractor has a header drive system including a header drive motor and a header drive pump driven by an engine for generating a source of hydraulic fluid under pressure for the header drive motor, and a ground drive system including a wheel drive motor and a wheel drive pump driven by the engine for generating a source of hydraulic fluid under pressure for the wheel drive motor. A controller receives input from sensors so as to monitor: a header drive demand value, a wheel drive demand value, an engine load value, and/or an engine RPM value for comparisons to acceptable threshold range to vary the target throttle value if outside of one of the ranges. The controller can also vary the displacement of the wheel drive pump and/or the wheel drive motor in response to variation of the target throttle value to maintain ground speed.

A ground height gauge assembly is provided. The ground height gauge assembly includes a shaft configured to be rotatably coupled to the header. The ground height gauge assembly includes a first arm coupled to the shaft and configured to simultaneously rotate with the shaft, the first arm defining a first length. The ground height gauge assembly includes a second arm pivotally coupled to the shaft and defining a second length, the second arm configured to be mounted in a first position and a second position. The second length of the second arm is dimensioned greater than the first length of the first arm. In the first position the second arm is configured to rotate independently of the first arm. In the second position the second arm is configured to be coupled to the first arm such that rotation of the first arm simultaneously rotates the second arm.

An agricultural apparatus comprises a propulsion unit and an implement connected to the propulsion unit. The implement comprises: (i) a main frame having a main frame weight, (ii) an operational unit; (iii) a unit support apparatus configured to interconnect the operational unit to the main frame; (iv) a height adjustment apparatus comprising a terrain contact element, the height adjustment apparatus connected to the unit support apparatus. The terrain contact element is operable to be positioned to contact the terrain surface level at a contact region such that the at least one terrain contact element supports the unit support apparatus at a vertical separation distance above the terrain surface. The height adjustment apparatus is operable to adjust the vertical separation distance of the unit support apparatus above the terrain surface and thereby adjust a vertical separation distance of the operational unit above the terrain surface.

A work vehicle includes a chassis, and a work implement movably coupled to the chassis and configured to perform a field-engaging function. The work machine also includes an actuator coupled to the work implement and configured to adjust a position of the work implement relative to a ground surface. The work machine further includes a controller in communication with an output device and a communication module. The controller is configured to monitor a location of the work machine via the communication module. The controller is also configured to load a field map from a field map database, the field map identifying at least one impact event comprising a geotagged location. The controller is further configured to display an alert via the output device in response to the location of the work machine approaching within a predetermined distance from the geotagged location.
