An agricultural header comprises a first frame, a second frame, an endless side draper belt supported by the first frame, an endless center draper belt positioned in register with the side draper belt to receive cut crop laterally therefrom, an inter-frame flexible seal coupled to the first frame and the second frame. The first frame is coupled for movement relative to the second frame. The flexible seal underlies the side draper belt to receive cut crop that falls from the side draper belt and is arranged relative to the center draper belt to guide fallen crop toward the center draper belt. The flexible seal is configured to flex to accommodate movement of the first frame relative to the second frame.

An agricultural vehicle header includes a frame, a front conveyor, and a rear conveyor. The frame extends in a lateral direction from a first end to a second end and has a leading edge, and a feeder housing opening positioned behind the leading edge with respect to a forward direction. The front conveyor is attached to the frame behind the leading edge with respect to the forward direction, and includes a front movable surface configured to move an adjacent portion of crop material towards the feeder housing opening. The rear conveyor is attached to the frame behind the front conveyor, and has a rear belt having an operative surface that faces in the forward direction and is configured to move an adjacent portion of crop material towards the feeder housing opening.

A draper belt tensioning system having a frame, roller, control link, and tension link. The roller is movable relative to the frame. The control link has a proximal end pivotally attached to the frame, and a distal end that is remote from the proximal end. The tension link has a proximal end connected to the roller and a distal end connected to the control link at a connection location offset from a control link pivot axis. The control link is movable between a locked position in which the connection location is on a first side of the roller rotation axis and the control link pivot axis, a centered position, and an unlocked position in which the connection location is on another side of the roller rotation axis and the control link pivot axis. The control link has a greater angle in the locked position than in the unlocked position.

A header for a combine harvester includes a conveyor belt for conveying crop material in a conveyance direction, and an adjusting device for adjusting a tension of the conveyor belt. The adjusting device includes a cable that is movable with respect to a frame member of the header. A portion of the cable that is either directly or indirectly attached to one end of a roller for the conveyor belt extends either parallel to or substantially parallel to a tensioning direction of the conveyor belt for adjusting the tension of the conveyor belt. The conveyor belt may be an infeed conveyor belt or a lateral conveyor belt of a draper header, for example.

A process for conveying a flow of harvested crop along a first conveyor, which is configured to convey the flow along a first direction, and a second conveyor arranged downstream of the first conveyor and which is configured to convey the flow along a second direction different from the first direction. The process includes operating the first conveyor at a variable conveyor speed presenting a cycle of acceleration and deceleration, the cycle being operable to ensure a spatial repartition of the flow of harvested crop on the second conveyor, which receives the flow at a location that is variable according to the first direction.

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 draper belt assembly for an agricultural harvester that includes a first roller, a second roller, and a draper belt surrounding the first and second rollers. The draper belt includes a front end, a rear end opposite the front end, and an upper surface extending from the front end to the rear end having a width substantially parallel to a longitudinal axis of one of the first and second rollers. The draper belt further includes a plurality of spaced apart lugs each extending in the widthwise direction having an anterior end distal to the rear end and a posterior end proximal to the rear end, wherein the anterior end is spaced from the front end of the draper belt at least about 15 mm.
