A harvester head reel may include a bat support and an extendable bat supported by the bat support. The extendable bat may have a first segment and a second segment overlapping the first segment. The harvester head reels may further include a first finger extending from the first segment and a second finger extending from the second segment.

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 reel assembly of an agricultural header includes a first arm configured to support a reel of the reel assembly and a first pivot joint configured to pivotally couple the first arm to a frame of the agricultural header. The first pivot joint is configured to enable the first arm to pivot about a first local lateral axis of the agricultural header and about a longitudinal axis of the agricultural header relative to the frame. In addition, the reel assembly includes a second arm configured to support the reel and a second pivot joint configured to pivotally couple the second arm to the frame. The second pivot joint is configured to enable the second arm to pivot about a second local lateral axis of the agricultural header relative to the frame and to substantially block pivoting of the second arm about the longitudinal axis relative to the frame.

The disclosure provides a system and a method for controlling a reel of a combine harvester, wherein, the system comprises a satellite positioning receiver, a driving device, a controller and a rotating speed sensor; the rotating speed sensor collects and transmits an actual rotating speed of the reel to the controller, and the controller provides the driving device with a speed regulation signal according to the actual rotating speed and the operation running speed. The disclosure may realize that the rotating speed of the reel can be automatically, accurately and quickly adjusted according to the operation running speed of the combine harvester during the operation of the combine harvester, and improve the operation efficiency and quality while ensuring the crop feed quantity.

Method, apparatus, and non-transitory computer readable media for detecting reel-crop engagement for a header of a harvester. The header includes a reel configured to draw crop from a crop field toward the header as the harvester moves through the crop field and at least one crop detector mounted to the reel. Data is received from the at least one crop detector mounted on the reel, processed, and used to detect reel-crop engagement.

An agricultural harvester is disclosed. The agricultural harvester includes a cutting unit that has a cutting table adjustable in its cutting table length, a reel adjustable to a reel vertical position and reel longitudinal position, an inclined conveyor downstream from the cutting unit, and a driver assistance system. The driver assistance system autonomously determines, using at least one input variable, at least one machine parameter and specifies the machine parameter to the cutting unit. The machine parameter can include one or more of the cutting table length, the reel vertical position, or the reel longitudinal position. In particular, the driver assistance system may determine a harvested material throughput and a vibration coefficient describing the fluctuation in the harvested material throughput in a region lying in front of the threshing system and adapt or modify the cutting table length based on the determined vibration coefficient.
