A harvest head having a device to remove grains from plants to be harvested and a device to transfer harvested grains to a feeder and to a discharge tube. The harvest head having a support structure; a threshing comb; a first conveyor belt; a second conveyor belt, the threshing comb transfers the grains into the first and the second conveyor belts. The first and the second conveyor belts are convergent. A transverse conveyor belt is located between the first conveyor belt and the second conveyor belt. A reinforcement arranged on the back and the front cover and projecting out of the harvest head. The first and the second convergent conveyor belts carry the grain to the transverse conveyor belt, the transverse conveyor belt introduce the grains into a feeder that ends in a discharge tube. The convergent conveyor belts and the transverse conveyor belt are bands made of composite resins.

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 header for an agricultural vehicle includes: a header frame; a flexible cutter supported by the header frame and including a plurality of cutting edges; a reel including a plurality of reel sections movably supported by the header frame, each of the reel sections including a plurality of tines and being independently movable from the other reel sections; and at least one rigid link connecting the flexible cutter to one of the reel sections, the at least one rigid link being configured to transmit flexing forces acting on the flexible cutter to the connected one reel section such that a substantially constant separation is maintained between the flexible cutter and the connected one reel section.

A dual conveyor assembly for a windrower includes upper and lower conveyors. Each conveyor includes an endless conveyor element and rotatable supports spaced along a longitudinal conveyor path and entrained by the endless conveyor element. The endless conveyor elements define vertically spaced opposed runs that define the longitudinal conveyor path therebetween. The opposed runs are operable to be driven together to move a flow of severed plant material along the path. At least one of the opposed runs is shiftable relative to the other opposed run in an upright direction, while the runs are driven together, such that the opposed runs remain in moving engagement with the flow of severed plant material as the amount of severed plant material passing between the opposed runs varies.

A crop unloader system comprising: an elevator assembly, a boom assembly, a flexible drive, and a tensioning assembly. The elevator assembly has a frame, an elevator drive and drive motor, and an elevator drive output. The boom assembly has a frame connected to the elevator frame at a boom pivot axis to rotate through a range of motion, and an unloader drive input. The flexible drive is operatively connected between the elevator drive output and the unloader drive input. The tensioning assembly has a tensioner link and a control link that are pivotally to each other and with one of the two links each pivotally connected to one of the boom and elevator frame. An idler wheel is on the tensioner link. The tensioning assembly maintains a tension load on the endless flexible drive within a predetermined range, throughout the range of motion of the boom frame.
