An agricultural system with an agricultural harvester has a terahertz sensor. The terahertz sensor includes at least one a terahertz source disposed to direct electromagnetic radiation toward a harvest material of the agricultural harvester. A terahertz detector is disposed to detect the terahertz electromagnetic radiation after the terahertz electromagnetic radiation interacts with the harvest material. A controller is operably coupled to the terahertz detector and is configured to detect a harvest-related parameter based on a signal from the terahertz detector and to perform an action based on a detected parameter.

A round bale or module building assembly with a frame having a first wall and a second wall separated from one another by a module width and a plurality of rollers positioned between the first wall and the second wall, the plurality of rollers defining at least one belt path. Wherein, at least two rollers of the plurality of rollers have a combined width configured to substantially span the module width.

A fan assembly that has a fan hub having a plurality of blades extending radially therefrom and having a variable pitch and a controller in communication with the fan assembly to reposition a pitch of the plurality of blades. The controller establishes a variable maximum pitch of the plurality of blades based on an ambient temperature.

One or more techniques and/or systems are disclosed for a harvester vehicle that includes a crop processing system comprising at least an accumulator and a round module builder. The harvester vehicle has a feedback fusion system that operably provides crop processing data indicative of an estimated accumulator fill level to a crop feed rate control system. The feedback fusion system has a plurality of feedback devices that operably provide feedback signals including data indicative of two or more of: crop mass flow, module builder status, module size, and accumulator fill level. The feedback fusion system has a control module that operably receives the feedback signals and generates an accumulator fill level signal based at least upon two or more of the feedback signals. The accumulator fill level signal is indicative of the estimated fill level in the accumulator.

An information map is obtained by a cotton harvesting system. The information map maps values of a first characteristic to different geographic locations in a worksite. An in-situ sensor detects a value of a second characteristic as the cotton harvester operates at the worksite. A predictive map generator generates a predictive map that predicts values of the second characteristic at the different geographic locations in the worksite based on a relationship between the values of the first characteristic in the information map and values of the second characteristic detected by the in-situ sensor. The predictive map can be output and used in automated machine control.

A method and system of a pneumatic conveying system for moving separated grain and small plant material to an onboard storage tank or out of the combine harvester. The pneumatic conveying system having a gateway for introducing the material into an air flow channel, and with a diverter valve or an airlock directing separated grain and small plant material to the tank or outside of the harvester.

A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.

A module builder includes a wrap floor system including a wrap floor belt wrapped around a front belt sheave and a first drive system coupled to the wrap floor system. The first drive system includes a main drive belt coupled to a rear belt sheave and the front belt sheave, wherein in an engagement mode of operation the main drive belt is tensioned to rotate the rear belt sheave, and in a disengagement mode of operation the main drive belt loses tension to cease rotation of the rear belt sheave. The builder includes a second drive system coupled to a baler belt to drive the baler belt into a module forming chamber. The first drive system further includes one or more of a rear lower gate roller, friction wheel, wrap box roller, electric clutch, or motor to engage and drive the main drive belt.
