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.

An agricultural harvester comprises a feederhouse pivotally attached to a chassis, where the feederhouse defines a conduit for conveying crop material rearwardly from a front opening. A header interface frame is pivotally mounted to the feederhouse over the front opening to permit header pitch adjustment around a pitch adjustment axis. Upper and lower linear actuators are connected on one side of the feederhouse between the feederhouse and interface frame to control the pitch adjustment.

A nut row harvester has a nut hopper attached to a conveyor system. The nut row harvester has first and second frame sections that are pivotable relative to each other. A delivery end of the conveyor is moveable from a lower or harvesting position to an upper or dumping position. The nut hopper moves between the upper and lower positions with the end of the delivery conveyor.

A cogged drive arrangement for an endless belt conveyor for a feederhouse of an agricultural combine has a first drive wheel with an axis of rotation, a hub extending around the axis of rotation, flanges fixed to an outer edge of the hub and extending outward from the hub and a plurality of cogs fixed to the outer ends of the flanges.

A conveyor guide unit for use in an elevator of a sugarcane harvester comprises a housing, an axle positioned in and supported by the housing, and a rotor mounted to the axle for rotation about a rotation axis and configured to interface with a conveyor of the elevator. The axle and the rotor mounted thereto are selectively repositionable axially along the rotation axis relative to the housing for lateral adjustment of the rotor relative to the conveyor.

An agricultural harvesting head.

An agricultural harvesting head includes a laterally extending frame with several spaced apart float arms pivotally coupled to the frame at their rear ends, and a reciprocating knife fixed to the forward ends of the float arms, wherein the float arms are constrained to pivot with respect to the frame about pivot points that are lower than the reciprocating knife.

A header for an agricultural harvester comprising a frame and an epicyclical drive operatively connected to the frame. The epicyclical drive includes a first rotatable wheel having a first central rotational axis and a first flange. The first flange includes a first eccentric axis rotatable about the first central rotational axis, and a first output shaft spaced from the first eccentric axis. The epicyclical drive further includes a second rotatable wheel having a second central rotational axis and a second flange. The second flange includes a second eccentric axis rotatable about the second central rotational axis, and a second output shaft spaced from the second eccentric axis. The header further includes a first cutter bar directly connected to the first output shaft and a second cutter bar directly connected to the second output shaft. Operation of the epicyclical drive results in substantially linear oscillating motion of the cutter bars.

A shaft and sprocket assembly having an elongate shaft, a sprocket wheel and at least one bracket member. The sprocket wheel encircles and engages the shaft wherein torque is transferrable between the shaft and the sprocket wheel. The sprocket wheel includes radially outwardly extending teeth and is formed by a plurality of sprocket members. Each of the sprocket members defines an angular portion of the sprocket wheel less than 360 degrees. The bracket member detachably secures the individual plurality of sprocket members together thereby allowing the sprocket members to be easily removed from and installed on the shaft. The bracket member is positioned such that no torque is directly transferred from the shaft to the bracket member. The shaft and sprocket assembly can be used in a variety of applications including in the feederhouse of an agricultural combine.

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.
