An agricultural work machine is provided comprising a surroundings detection device for detecting a surroundings in sections, and one or more controllable working elements, wherein the surroundings detection device generates surroundings detection signals, which can be processed in a control and regulating device assigned to the agricultural work machine, wherein the surroundings detection device is designed as a scanner, which scans the surroundings in scanning planes, and wherein each scanning plane is assigned to the control of working elements.

An agricultural production machine, such as a combine, forage harvester or tractor, is disclosed. The agricultural production machine includes a drive assembly with an internal combustion engine, an electric energy supplying system having an electric auxiliary machine, and a driver assistance system with a control system that is configured to control the internal combustion engine, the electric auxiliary machine, and at least one power consumer that can be driven by the drive assembly. The internal combustion engine operates at the lowest possible rotational speed, with the electric energy supplying system configured to support the internal combustion engine by connecting the electric auxiliary machine at this lowest possible rotational speed when connecting a load.

An arrangement for control of the drive speed of a harvester comprises an internal control loop for control of the drive speed of the harvester, to which can be sent a set value and an actual value of a throughput-dependent parameter, and also an external control loop to make available the set value of the throughput-dependent parameter for the internal control loop, to which set and actual values regarding the power output of a drive of the harvester can be sent as input parameters.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.

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.

An agricultural method for preventing roll-back of an agricultural vehicle may include receiving a roll-back prevention input from a speed setting device indicative of a command to increase the transmission speed of the hydrostatic transmission while a service brake of the agricultural vehicle is engaged. Further, the method may include adjusting a speed mapping for the speed setting device from a predetermined speed mapping to a roll-back speed mapping in response to the roll-back prevention input, with the roll-back speed mapping being associated with a reduced speed range. Additionally, the method may include determining a transmission control command associated with a current position of the speed setting device based on the roll-back speed mapping and controlling an operation of the hydrostatic transmission to adjust the transmission speed based at least in part on the transmission control command.

An agricultural system obtains a residue map that maps residue characteristics of a field, wherein the residue map is based on data collected at or prior to a first time. The agricultural system obtains supplemental data indicative of characteristics relative to the worksite, the supplemental data collected after the first time. A residue characteristic confidence output, indicative of a confidence level in the residue characteristics indicated by the residue map, is generated based on the residue map and the supplemental data. In some examples, a mobile machine is controlled based on the residue characteristic confidence output.

A fan control system for a variable pitch fan of a work vehicle includes a blade pitch module that adjust a pitch of a plurality of blades of the variable pitch fan to generate airflow in a first direction. A reversing module selectively commands a fan reversal that includes instructing the blade pitch module to temporarily adjust the pitch of the plurality of blades to generate airflow in a second direction. A first timer module, in response to the reversing module commanding the fan reversal, resets and increments a first timer and compares the first timer to a first threshold. A first reversal prevention module, in response to the first timer being less than the first threshold, prevents the reversing module from commanding a fan reversal by indicating that a first type of fan reversal is not permitted.

A control portion includes a vehicle-position acquiring portion, a field-contour setting portion, a region setting portion, and a display processing portion. The vehicle-position acquiring portion acquires position information indicating a position of the combine harvester traveling on a field. The field-contour setting portion sets a contour of a field on the basis of a plurality of pieces of the position information. The region setting portion sets a region not subject to a work indicating a region which is not a target for the work by the combine harvester inside the field or outside the field on the basis of the contour. The display processing portion causes a field image showing the field and an identification image for identifying the region not subject to the work, to be displayed on a display portion.

Techniques and/or systems are disclosed herein for controlling a harvesting rate in a harvester vehicle having a crop feed rate control system that provides crop processing data to a vehicle control system. The crop feed rate control system includes: one or more feedback systems that operably provide a feedback signal including data indicative of a detected load amount for crop processing components of the crop processing system and indicative of a target load amount for the crop processing components; a first control module that operably receives the feedback signal and generates a controlling load signal based at least upon the feedback signal, the controlling load signal indicative of a controlling component of the crop processing components; and a second control module that operably receives a targeted load signal and the controlling load signal, the second control module operably generating crop processing data indicative of a target harvesting rate.
