摘要： A predictive map is obtained by an agricultural system. The predictive map maps characteristic values at different geographic locations in a field. A geographic position sensor detects a geographic location of an agricultural harvester at the field. A control system generates a control signal to control a reel subsystem of the agricultural harvester based on the geographic location of the agricultural harvester and the predictive map.

摘要： In a harvester/header combination according to the invention, the header is a crop pick-up header (2) coupled to a forage harvester (1). The header comprises a frame (10) and a rotatable reel (13) configured to collect crops from the ground, a rotatable auger (20) provided with two oppositely wound helicoidal flights (26), and one or more windguard rolls (15). The auger is rotatable with respect to a pair of support arms (21) which are themselves pivotable relative to the frame, so that the pivoting movement of the arms results in lowering or raising the auger (20). According to the invention, the header comprises at least one set of actuators (18,19) capable of actively raising the auger and the windguard roll(s) and the harvester/header combination comprises a control unit (46) configured to execute a sequence of steps for removing a foreign object from the header, after detection of the object and stoppage of the harvester's feed rolls (51). The removal sequence includes raising the auger while rotating the auger in the reverse direction, followed by lowering the auger while maintaining said reverse rotation.

摘要： 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.

摘要： An agricultural header having a frame (120), a first support arm (124), a second support arm (124) spaced from the first support arm (124), a reel (116) extending from a first reel end (130) rotatably mounted to the first support arm to a second reel end (132) rotatably mounted to the second support arm, a first actuator (128, 300, 400, 504, 600, 700) operatively connected to the frame (120) and the first reel end (130) and configured to move the first reel end (130) relative to the frame (120), a second actuator (128, 302, 402, 506, 602, 704) operatively connected to the frame (120) and the second reel end (132) and configured to move the second reel end (132) relative to the frame (120), and a control system (200, 608, 708) configured to alternately operate the first actuator (128, 300, 400, 504, 600, 700) and the second actuator (128, 302, 402, 506, 602, 704) in repeating alternating incremental steps to thereby move the reel (116) from a first reel position relative to the frame (120) to a second reel position relative to the frame (120). A combine (100) having such a header is also provided.

摘要： Die vorliegende Erfindung bezieht sich auf eine Erntemaschine (1) mit einem Schneidwerk (2) zum Anbau an eine Erntemaschine (1) mit einem sich im Wesentlichen über die Arbeitsbreite (4) des Schneidwerks (2) erstreckenden Rahmen (6), an der Vorderseite des Schneidwerks (2) angeordneten und mit dem Rahmen (6) verbundenen Schneidelementen (14), Förderflächen (16) und Förderorganen (18) zur Abförderung des geschnittenen Ernteguts von den Schneidelementen (14) zu einer Abgabestelle (20), eines der Förderorgane (18) ist eine Haspel (22), die sich quer zur Arbeitsrichtung (A) des Schneidwerks (2) über die Arbeitsbreite des Schneidwerks (2) erstreckt, und die Haspel (22) ist von schwenkbeweglich am Rahmen (6) befestigten Haspeltragarmen (26) gehalten, die über einen hydraulischen Verstellantrieb zur Höhenverstellung der Haspel (22) höhenverstellbar sind, sowie auf ein entsprechendes Schneidwerk.
Um die Sicherung der Haspel bei Wartungsarbeiten am Schneidwerk zu vereinfachen, wird vorgeschlagen, dass der Hydraulikkreislauf (50), mit dem der hydraulische Verstellantrieb (28) antriebsverbunden ist, eine gesonderte Verriegelungsfunktion über ein Hydraulikventil (46) aufweist.-

摘要： A rephasing system may include a first hydraulic cylinder, a second hydraulic cylinder, a first rephasing valve, a second rephasing valve and a controller. The first hydraulic cylinder and the second hydraulic cylinder first and second pistons, respectively. A first hydraulic fluid line connects a hydraulic supply to a first side of the first piston while a second hydraulic fluid line connects a second side of the first piston to a first side of the second piston. The first rephasing valve fluidly couples the first side of the first piston to the first side of the second piston while the second hydraulic fluid line fluidly couples the second side of the second piston to the hydraulic supply. The controller selectively opens and closes the first and second rephasing valves to re-phase the first and second pistons.
