Methods and apparatus to identify headlands are disclosed. A disclosed example apparatus to identify a headland of a field includes an image analyzer to generate an image from data corresponding to path information of at least one field operation performed on the field, a mask generator to generate a mask of the image based on the image, and a headland identifier to identify the headland in the field based on the mask.

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.

A harvest analysis system, intended to be used in a machine (2, 3) for harvesting agricultural products, e.g. combine (2), forage harvester (3) or the like, comprising at least one image acquisition device (4, 40) and at least one processing unit (1), connected to said acquisition device (4, 40) and in turn comprising: at least one memory module (10) in which at least a first reference image is stored; and at least one comparison module (11, 12) configured to perform a comparison between the images of the harvested products, acquired by said device (4, 40) and said reference image.

A combine harvester includes a belt cutting unit comprising a center belt for conveying harvest to an intake roller and/or to an intake channel of a grain conveyor, and a transverse conveyor belt disposed each on the left-hand side and the right-hand side of the center belt, to convey harvest to the center belt. The center belt, left-hand and right-hand transverse conveyor belts are behind a cutter bar, seen in the direction of travel, with each being operated with an individual belt speed. The combine harvester and/or belt cutting unit has a control unit configured to automatically control the belt speeds of the left-hand and right-hand transverse conveyor belts as a function of a forward travel speed, and the belt speeds of the center belt as a function of the forward travel speed or as a function of the belt speeds of the left-hand and right-hand transverse conveyor belts.

A self-propelled forage harvester is disclosed. The forage harvester includes a feed device, a chopping device comprising a cutterhead equipped with cutting blades and a shear bar for comminuting harvested material, a drive, and a driver assistance system for controlling at least the chopping device. The driver assistance system includes a memory for saving data and a computing device for processing the data saved in the memory, wherein the chopping device and the driver assistance system in combination form an automatic chopping system in that the computing device continuously determines a compaction of the comminuted harvested material using harvested material parameters during a harvesting process in order to autonomously ascertain and specify a cutting length to be adapted for maintaining nearly constant compactability.

The present invention is related to a self-propelled forage harvester (1) comprising one or more sensors (15) mounted on the spout (30) of the harvester, and configured to measure the speed of the crop flow passing through the spout. The harvester is further equipped with a feed roll control unit (8) configured to receive a signal from the sensor and further configured to stop the rotation of the feed rolls (4,5) when the speed is lower than a pre-defined threshold, indicating that a blockage has occurred in the spout. According to an embodiment, the harvester is further provided with a hatch door arranged in the bottom of the spout. The hatch door enables the removal of the blocked crops after a blockage has occurred. In this way, a blockage can be detected quickly and removal of the blockage may also be realised in a fast and efficient way.
