A method and apparatus for controlling a header height of a combine harvester that includes a header, a ground speed sensor, a ground height sensor configured to detect a ground contour directly beneath the header, a forward looking sensor (FLS) configured to detect a ground contour forward of the header, and a controller. The controller receives signals from the ground speed sensor, the ground height sensor and the FLS, and calculates a header height output as a function of (i) an output of the ground speed sensor, which represents a ground speed of the combine, (ii) an output of the ground height sensor, and (iii) an output of the FLS. The controller is further configured to weight the outputs of the ground height sensor and the FLS as a function of the speed of the combine harvester in calculating the header height output.

A multi-layer segmentation/stalk cutter device for a first season of double-crop rice and a control method, and a combine harvester for a first season of double-crop rice, the multi-layer segmentation/stalk cutter device comprising: a cutting platform, a segmenting cutter and a stalk cutter, at least one segmenting cutter being disposed at a lower rear portion of the cutting platform, the segmenting cutter being hinged on a moving chassis, and a second execution mechanism controlling the cutting height of the segmenting cutter; the stalk cutter being disposed at a lower rear portion of the segmenting cutter, the stalk cutter being hinged on the moving chassis, and a third execution mechanism controlling the cutting height of the stalk cutter.

One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

A harvesting header for attachment to a harvesting machine, the header including two or more sub-assemblies each which includes a respective crop gathering mechanism and a respective drive mechanism coupled to operate the crop gathering mechanism. The drive mechanisms for the respective sub-assemblies are operable independently of one another to enable them to run at different speeds when the harvesting machine is performing a turn manoeuver.

A priori geo-referenced data is obtained for a worksite, along with field data that is collected by a sensor on a work machine that is performing an operation at the worksite. A predictive model is generated, while the machine is performing the operation, based on the geo-referenced data and the field data. A model quality metric is generated for the predictive model and is used to determine whether the predictive model is a qualified predicative model. If so, a control system controls a subsystem of the work machine, using the qualified predictive model, and a position of the work machine, to perform the operation.

A cutting unit (1) that has a cutter bar (6) that is operated rigidly or flexibly, depending on the harvest conditions, which can be operated in at least two different operating modes, wherein the cutting unit (1) includes a first sensor assembly (1) disposed on the cutting unit (1) that can be deactivated, which is for operating the cutting unit (1) in a first operating mode, and a second sensor assembly (17) for operating the cutting unit (1) in a second operating mode, wherein, when switching between the at least two operating states, the first sensor assembly (13) or the second sensor assembly (17) is activated without interruption in operation, to execute a distance determination, depending on the selected operating mode.

A dual cut header assembly including a header, a chopper suspended from the header, and an actuator system comprising one or more cylinders. The actuator system solely connects the chopper to the header. The dual cut header assembly further includes at least one sensor for measuring a state of the chopper and an actuator steering module connected to the actuator system. The header is configured to be lifted by an agricultural vehicle to cut crop material from a field at a first height. The chopper is configured to cut the crop material at a second height lower than the first height. The actuator steering module is configured to automatically adapt the distance based on the measured state of the chopper.

An agricultural vehicle header system having a center section, an inboard height sensor located on the center section between a lateral centerline and an end of the center section, a wing section movably attached to the end of the center section, a number of outboard height sensors located on the wing section between an inboard end and an outboard end of the wing section, and a header control subsystem. Each of the outboard height sensors is configured to output a respective outboard height sensor signal. The header control subsystem is operatively connected to the outboard height sensors, and configured to receive the respective outboard height sensor signals from each of the outboard height sensors, and generate a single emulated outboard height sensor signal based on the outboard height sensor signals.
