A harvester may include a crop path along which crops are moved, a working member to interact with weed seeds moving along the crop path and a controller. The controller is to receive data indicating forthcoming weed seeds and is to output control signals controlling the working member based on the data.

A monitoring system for a combine harvester. The monitoring system includes a sensor configured to provide a measurement wave to a flow of crop residue on the harvester and to receive a response wave from the flow of crop residue. The monitoring system further includes a processor having an input terminal for receiving a response signal of the sensor representative of the response wave. The processor is configured to determine a crop parameter associated with the density of the flow of crop based on the response signal of the sensor. The processor further has an output terminal for outputting a density signal representing the crop parameter.

An agricultural harvester includes a threshing assembly configured to thresh crop material received from a feeder of the agricultural harvester. The threshing assembly, in turn, includes a concave and a rotor positioned relative to the concave such that a gap is defined between the concave and the rotor. Furthermore, the agricultural harvester includes an actuator configured to move the concave relative to the rotor to adjust a size of the gap. Additionally, the agricultural harvester includes a tailings assembly configured to receive incompletely threshed crop material that has passed through the concave. Moreover, the agricultural harvester includes an imaging device configured to capture image data depicting the incompletely threshed crop material present within the tailings assembly and a computing system communicatively coupled to the imaging device. As such, the computing system is configured to determine an amount of the incompletely threshed crop material present within the tailings assembly based on the captured image data. In addition, the computing system is configured to control an operation of the actuator based on the determined amount of the incompletely threshed crop material present within the tailings assembly.

A computer-implemented method includes obtaining harvest data indicative of a prior harvesting operation on a field, identifying a region of the field having already-harvested crop plants based on the harvest data, detecting a characteristic of crop plants in a field in a path of an agricultural harvesting machine in a direction of travel, generating, based on the detected characteristic, a height metric representing a height of the crop plants on a particular area of the field, and generating a control signal to control the agricultural harvesting machine based on the height metric and the identified region.

A combine harvester includes a grain pan that is arranged to catch a crop stream. The grain pan is driven in a fore and aft oscillating manner to convey the crop stream rearwardly across a conveyance surface to a rear edge. The grain pan is provided with an upright panel extending in a fore and aft direction on the conveyance surface. A grain cleaning system is arranged to receive the crop stream from the grain pan. A crop stream analysis system is provided for analysing a vertical section of a crop material layer disposed on the grain pan. The analysis system includes a vertical array of photoelectric sensing devices mounted to the panel. Each photoelectric sensing device is configured to sense a reflectance of crop material disposed against the panel. A processor is configured to receive reflectance signals from the photoelectric sensing devices and determine a material stratification status from the reflectance signals.

A combine harvester, and method of control involves conveying a crop material stream through a grain cleaning system which has screening apparatus. A cleaning airstream (X) is generated by a fan which is driven by a hydraulic fan drive system. The cleaning airstream (X) is directed through the screening apparatus. A fan drive pressure of a hydraulic supply line within the fan drive system is measured with a sensor. A material quantity value is calculated from the fan drive pressure. A working unit of the combine harvester is controlled using the material quantity value.

A mechanical arrangement introduced into a grain collecting and processing machine using a hinged traction bar is provided, wherein two swivel gearboxes are installed, allowing the head to be assembled in the center and the machine to work laterally displaced over the tractor vehicle, on both sides, thus facilitating both the operation and the collection process. A grain collecting and processing machine including the mechanical arrangement is also provided.
