摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method for dynamically operating a header float system of an agricultural vehicle having a header movably mounted to a frame by an actuator and a flotation adjustment system that relies on ground-contact force measurement. The method includes: determining an initial zero value load sensor output signal representative of an initial position of the header raised out of contact with the ground surface, calibrating the sensor with the initial zero value, operating the header to process a crop material, detecting a subsequent position of the header out of contact with the ground surface, determining a subsequent zero value representative of the subsequent position of the header, and re-calibrating the sensor with the subsequent zero value. Also, an agricultural vehicle having a header operated as described above.

摘要： A method for dynamically operating a header float system of an agricultural vehicle having a header movably mounted to a frame of the agricultural vehicle by an actuator. The method includes: determining a target ground reaction force between the header and a ground surface located below the header, determining an actual ground reaction force between the header and the ground surface, comparing the actual ground reaction force to the target ground reaction force, and upon determining that the actual ground reaction force differs from the target ground reaction force by a predetermined amount, operating the actuator to reduce a difference in value between the actual ground reaction force and the target ground reaction force. An agricultural vehicle having a header operated as described above is also provided.

摘要： A boom mower attachment that moves a cutting mechanism in a first movement, a second movement, and a third movement by only using two motions of a single control and method of use thereof is provided. The boom mower may include a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. An implement control system including a control, at least one function switching mechanism, and an implement is also provided. Activation of the control is operative to move the implement in a first mode, a second mode, and a third mode by only using two motions of the control.

摘要： A harvesting head for an agricultural combine includes a frame and a support arm coupled to the frame. The support arm is configured to move between an unlocked state in which the support arm is moveable relative to the frame and a locked state in which the support arm is fixed relative to the frame. The harvesting head includes cutting teeth supported by the support arm relative to the frame. The cutting teeth are configured to move relative to the support arm in a reciprocating motion along a longitudinal axis of the frame. The harvesting head includes a gauge member coupled to the frame. The gauge member is configured to sense a height of the frame relative to a surface. The harvesting head includes a control assembly configured to move the support arm into the locked state based on the height of the frame relative to the surface.

摘要： A ground contour sensing system and method for a vehicle with a mowing head. The system includes a sensor system that measures a ground contour in front of the mowing head, and generates contour measurement signals; and a controller that determines whether to move the mowing head based on the contour measurement signals, and generates movement commands for the mowing head when it determines to move the mowing head. The mowing head can include tilt and lift cylinders, and the controller can determine whether to move the mowing head using the tilt or lift cylinders. The sensor system can include a pivot arm that moves in response to changes in the ground contour, and an angle sensor that measures an angle of the pivot arm. There can be one or more sensor systems positioned between the right and left sides of the mowing head.

摘要： Harvesting machines and agricultural harvesting heads for harvesting machines are disclosed herein. A harvesting machine includes a main frame, a cutter assembly, and a conveyor system. The cutter assembly is pivotally coupled to the main frame. The cutter assembly includes a cutter bar configured to sever crop material adjacent to the ground and a cutter frame configured to support the cutter bar for pivotal movement relative to the main frame. The conveyor system is coupled to the main frame and configured to convey severed crop material in a rearward direction away from the cutter bar toward a central feed drum of the harvesting machine.
