An agricultural vehicle includes: a chassis; a header carried by the chassis and configured to cut crop material; a chopper carried by the chassis downstream of the header; a spreader assembly carried by the chassis downstream of the chopper; and a windrow assembly carried by the chassis downstream of the chopper. The windrow assembly includes: a windrow chute defining a chute surface and a leading edge downstream from the chopper; and a rotatable conveyor associated with the leading edge and having a surface with at least one conveyor projection extending from the surface, the at least one conveyor projection being configured to convey crop material toward at least one of the chute surface and the spreader assembly during rotation.

A cutting unit includes a center section arranged on a base frame and at least two side portions adjoining the center section, a knife bar extending basically over the entire width of the cutting unit, and at least one conveyor arranged behind the knife bar, which conveyor transports crops cut by the knife bar laterally in the direction of the center section, which has at least one conveying system conveying transverse to the transport direction of the conveyor, wherein the conveying system includes at least two rotating conveyor belts, which are arranged at an inclination at an angle () to the longitudinal axis (LA) of the center section.

A harvesting attachment for whole plant harvesting includes a pick-up for picking up plants from a field, a first transverse conveyor belt and a second transverse conveyor belt for conveying the plants picked up transversely in a direction toward of a longitudinal center plane of the harvesting attachment, and two longitudinal conveyor belts which are arranged side-by-side and adjacent to the longitudinal center plane of the harvesting attachment and are set up to convey the plants entering from the transverse conveyor belts rearward to a rear discharge point of the harvesting attachment. The two longitudinal conveyor belts are inclined vertically upward in a direction toward the center plane at least over part of their length along the center plane.

A combine comprising a feeder housing, and an auger for receiving harvested crop. The auger includes an auger tube rotatable around an auger axis, and a tined-tube positioned inside the auger tube and rotatable around a tined-tube axis that is offset from the auger axis, the tined-tube including fingers extending from the tined-tube and protruding through the auger tube to convey the harvested crop to the feeder housing.

A draper belt system is provided that includes a first draper belt assembly with first and second rollers, and a second draper belt assembly with third and fourth rollers. The third roller of the second draper belt assembly is disposed adjacent to the first roller of the first draper belt assembly. The first draper belt assembly is configured to pivot relative to the second draper belt assembly. Pivoting of the first draper belt assembly results in a change in a distance between the first and third rollers.

A combine draper header and method of floating a wing of the same from a center section of the draper header. The wing is movably supported with respect to the center section to enable movement of the wing between a first position and a second position. The wing is supported with respect to the center section with a resilient float element. Increasing amounts of energy are stored in the resilient float element through movement of the wing from the first position to the second position. The resilient float element is re-oriented with a float linkage to reduce the mechanical advantage of the resilient float element for supporting the wing through movement of the wing from the first position to the second position, thus buffering the wing from a force increase from the resilient float element.

In a draper harvesting head having a frame, a left side conveyor supported on the frame, a right side conveyor supported on the frame, a central conveyor supported on the frame and disposed between the left side conveyor and the right side conveyor, and a reciprocating knife fixed to the front of the frame and extending laterally across the frame, a method of controlling slippage between an endless conveyor belt of one of the left side conveyor and the right side conveyor and a crop mat carried on the endless conveyor belt is provided, including determining a speed of the endless conveyor belt and a speed of the crop mat; comparing a difference in the speed of the endless conveyor belt and the speed of the crop mat with a first threshold speed difference; and changing the speed of the endless conveyor belt based upon the step of comparing.

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 draper belt system is provided that includes first and second draper belt assemblies. The first draper belt assembly includes first and second rollers, and a draper belt looped around the first and second rollers. The first roller defines a first roller diameter, a first central longitudinal axis, and a first plane extending through the first central longitudinal axis. The second draper belt assembly includes third and fourth rollers, and a draper belt looped around the third and fourth rollers. The third roller defines a third roller diameter dimensioned smaller than the first roller diameter, a second central longitudinal axis, and a second plane extending through the second central longitudinal axis. The third roller of the second draper belt assembly is disposed adjacent to the first roller with the first central longitudinal axis extending parallel to the second central longitudinal axis, and the second plane offset from the first plane.

A feeding device for a flexible canvas or draper harvester characterized by upper beam (8) linked to a lower front beam (10) and joined by side covers (11) forming a frame, integral with a lateral stud supports (12) and a central stud supports (13) associated with a central lower beam (9) cut into three sections; the central stud supports (13) are integral with the anchors of the coupling device (15) and with the flexible body supports (14); the central stud supports (13) and lateral stud supports (12) are linked to the conveyor belts with flexible canvases (3, 4, 5 and 6), forming a central body and two laterals with space to accommodate a double row.
