Abstract: Systems and methods are provided for monitoring crop loss associated with a header arrangement operably couplable to an agricultural harvesting machine. One or more transceiver sensors are coupleable, in use, to the header arrangement and configured, in use, for transmitting measurement signals and receiving reflections thereof from an object within a sensing region of the sensor which at least partly includes a region below the header arrangement. Sensor data therefrom is processed to identify crop constituents present within the sensing region and a loss metric for an agricultural operation performed by the header arrangement is determined in dependence thereon. Operation of operable components of or otherwise associated with the header arrangement and/or the agricultural harvesting machine can be controlled in dependence on the determined loss metric.

Abstract: Systems and methods are provided for monitoring crop loss associated with a header arrangement operably couplable to an agricultural harvesting machine. A sensor response is received from a sensing element of a sensor arrangement provided as part of or otherwise associated with a sample unit, the sensor response being dependent on material constituents present within the sample unit, and where the sample unit is operably coupled to one or more functional components of the header arrangement. A measure of crop constituents provided by the sample unit is determined based on the sensor response and used to determine a loss metric for an agricultural operation performed by the header arrangement. Operation of one or more operable components of or otherwise associated with the header arrangement and/or the agricultural harvesting machine is then controlled in dependence on the determined loss metric.

Abstract: Differential speed stalk rolls mountable to a row unit of a row crop head. A first stalk roll body has an outer peripheral speed less than the outer peripheral speed of a second stalk roll body in lateral spaced relation. The stalk roll bodies may have modular and interchangeable body segments of different configurations.

Abstract: Differential speed stalk rolls mountable to a row unit of a row crop head. A first stalk roll body has an outer peripheral speed less than the outer peripheral speed of a second stalk roll body in lateral spaced relation. At least one of the first and second bodies includes a knife defining a knife plane normal to the axis of rotation of the first or second stalk roll. The stalk roll bodies may have modular and interchangeable body segments of different configurations.
