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.

An optical measuring device for the spectral measurement of a sample is disclosed. The optical measure device includes an integrating cavity that has a diffusely reflective interior in order to render the light in the integrating cavity diffuse, a light source that is configured to emit light of a predetermined wavelength range into the integrating cavity, and a sensor that is configured to receive light from the integrating cavity, wherein the integrating cavity comprises an optical opening, and wherein the optical measuring device is provided and configured to measure a sample located outside of the integrating cavity directly in front of the optical opening.

Embodiments of a kernel-level grain monitoring system include a grain camera positioned to capture bulk grain sample images of a currently-harvested grain taken into and processed by a combine harvester, a moisture sensor, and a display device. A controller architecture is coupled to the grain camera, to the moisture sensor, and to the display device. The controller architecture is configured to: (i) analyze the bulk grain sample images, as received from the grain camera, to determine an average per kernel (APK) volume representing an estimated volume of a single average kernel of the currently-harvested grain; (ii) repeatedly calculate one or more topline harvesting parameters based, at least in part, on the determined APK volume and the moisture sensor data; and (iii) selectively present the topline harvesting parameters on the display device for viewing by an operator of the combine harvester.

A combine includes: a yield measurement container (32) having a yield receiving opening (32a) for receiving at least some of grains supplied to a grain tank (15) which accumulates grains obtained by threshing, a yield discharge opening (32b) for discharging received grains, and a yield shutter (34) for opening and closing the yield discharge opening (32b); a yield measurement section for detecting, while the yield shutter (34) is closed, that a predetermined volume of grains has been accumulated in the yield measurement container (32) and then outputting a detection signal; a time calculation section for calculating, based on the detection signal, an accumulating time required to accumulate the predetermined volume of grains; and a yield calculation section for calculating a yield per unit travel based on a travel speed and the accumulation time.

A combine including: a measurement sensor that measures a retention volume amount of a grain retained in a grain tank; a determination unit that determines whether or not the retention volume amount measured by the measurement sensor exceeds a preset threshold; a notification unit that, if it is determined by the determination unit that the retention volume amount exceeds the threshold, notifies an operator of information indicating that the amount of the grain exceeds the threshold; a change unit that can change the threshold; and a communication unit that communicates with an external server. The change unit changes the threshold based on data received from the external server.

There are provided an engine controlling section for controlling a rotational speed of an engine, a horizontal posture controlling section for rendering a vehicle body frame to a horizontal posture by controlling a posture changing mechanism configured to change a posture of the vehicle body frame by an operation of an actuator utilizing power from the engine, a yield measuring section for measuring a yield of grains stored in a grain tank based on measurement result of a load cell configured to measure a weight of the grain tank, an activation operational tool for outputting an activation signal for activating yield measurement by the yield measuring section, and a yield controlling section configured to provide the engine controlling section with a high speed rotation instruction for driving the engine at a rated rotational speed in response to the activation signal and also to provide the horizontal posture controlling section with a horizontal posture instruction for rendering the vehicle body frame to the horizontal posture.

A harvesting system includes a crop unloading machine having a volume measurement device configured to measure a volume of harvested crops, and a crop transport vehicle including a weight sensor configured to sense a weight of the harvested crops. The crop transport vehicle can receive crops from the crop unloading machine. The crop transport vehicle communicates the sensed weight to the crop unloading machine and the crop unloading machine calculates a crop yield based upon the sensed weight, the volume and a state of the crop unloading machine.

Apparatus, systems and methods are provided for monitoring yield while harvesting grain. In some embodiments a template is provided for cutting an opening in a clean grain elevator plane. In some embodiments, a gauge and shims are provided for positioning a yield sensor on the clean grain elevator.
