A dynamic yield monitor system includes a plurality of instruments to measure harvested crop characteristics while a crop is in-flow within a harvester elevator. The system includes a volume instrument that measures a harvested crop volume from the in-flow harvested crop within the harvester elevator, and a weight instrument that measures a harvested crop weight from the in-flow harvested crop within the harvester elevator. Optionally, the system includes other instruments including a moisture and temperature instrument. A receiver and processing node communicates with the instrument. The receiver and processing determines variable harvested crop test weight based on at least the measured harvested crop volume and measured harvested crop weight of the in-flow crop. The receiver and processing node further determines a variable yield of the harvested crop based on the measured harvested crop volume, the measured harvested crop weight, and the variable harvested crop test weight.

A sensor system and a method for optical analysis of bulk material, having a sample space for receiving the bulk material that is to be examined, wherein a measurement section extending in the bulk material is realized in the sample space. In this case, means for changing the length of the measurement section are present. A harvester equipped, a laboratory or mobile system equipped with the system is also provided.

In one embodiment, a method implemented in an agricultural machine harvesting alfalfa plants, the method comprising: receiving, in real time, input corresponding to a plurality of sensed parameters corresponding to alfalfa plant height and cut alfalfa volume; associating the cut alfalfa volume to an alfalfa stem diameter; and automatically determining a feed quality value for the alfalfa plants based on the sensed alfalfa plant height and the alfalfa stem diameter.

A working machine, in particular a combine harvester, having multiple working elements for carrying out or assisting work, and a driver assistance system for controlling the working elements according to at least one processing strategy which can be specified by the operator and directed to the fulfillment of at least one quality criterion. The driver assistance system has a memory for storing data characterizing the processing strategy, a computing device for processing the data stored in the memory, and a graphical user interface. Competing quality criteria, weighted with respect to each other according to a weighting variable, are incorporated into the processing strategy. The weighting variable is visualized via a virtual control element of the graphical user interface and can be specified by the operator. The driver assistance system registers the strategy selection of the operator, predicts an optimization goal, and presents an optimization proposal for this predicted optimization goal.

A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch 66, a weight measurement decision unit 75 instructs a working state determination unit 71 to perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unit 75 does not instruct a load cell 39 to perform weight measurement.

A system and method of controlling an agricultural machine uses the following steps: (a) successively recording signals from at least one first sensor sensing at least one agronomic parameter of a field during an operation of the machine in the field, (b) successively recording signals from at least one second sensor sensing at least one operation parameter of the machine during the operation of the machine in the field, (c) spatially overlaying the signals of the first sensor and the second sensor, (d) determining from the overlaid values a respective zone in the field, and (e) controlling an actuator of the machine dependent on the determined zone in which the machine operates.

A system and method for automated grain inspection and analysis of results, that inspects grains using a plurality of light spectra, analyzes the results, and produces detailed reports from the analysis.

A user interface element includes a plurality of moveable outer points on a circular line and a fixed inner point inside the circular line, the fixed inner point being connected to each of the outer points by a straight line such that each pair of adjacent straight lines and a portion of the circular line between the adjacent straight lines defines a section of the graphical user interface element. The user interface is configured to, in response to interaction from the user, move any of the outer points along the circular line and independently of the other outer points to thereby change the size of two or more of the sections. Each section corresponds to one of a plurality of crop processing parameters, such that changing the amount of area within any section results in an adjustment to an operation of a crop processing system.

A spectrometric measuring head for forestry, agricultural and food industry applications comprises a housing having a window and a spectrometer that is arranged inside the housing and comprises a dispersive element and a sensor, a first light source for exposing a sample to light, which reaches the spectrometer through the window after having been transmitted and/or reflected by the sample, and a standard that can be exposed to light to provide a reference for the spectrometer, which standard can be exposed to light by a light source arranged in the housing.

A method of estimating the mass of crop entering into a grain tank on a harvesting machine, comprising the steps of mounting a load sensor on the upper bearing of a conveyor belt moving crop through the clean grain elevator into the grain tank, connecting the load sensor to a processor, using the load sensor to measure a load on the conveyor belt when no crop is present in the clean grain elevator, and also when crop is moving through the clean grain elevator, and comparing the load with no crop present to the load when crop is present to estimate the mass of crop moving through the clean grain elevator.
