Abstract: A header for a combine harvester includes a center section having a first draper belt configured to move crop material in a first direction. The header also includes a wing pivotably coupled to the center section about a pivot axis and extending laterally away from the center section. The header also includes a second draper belt coupled to the wing and configured to move crop material in a second direction different than the first direction. The wing and the second draper belt are in a fixed positional relationship with each other, such that the wing is configured to remain at a constant distance from the second draper belt at all points along the wing during pivoting movement of the wing.

Abstract: 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.

Abstract: A draper header for a combine, the draper header including an attachment frame adapted for attachment to the combine. A harvesting assembly includes a plurality of sections and a plurality of belts operable to feed crop material into the combine. The draper header is operable in a first mode that allows the plurality of sections to float relative to the attachment frame for ground following during harvesting, and in a second mode in which the attachment frame is raised to lift and support the harvesting assembly to be spaced above the ground. A hydraulic leveling system includes at least one leveling actuator. A valve is operable in response to the movement of the draper header into the second mode to direct pressurized hydraulic fluid into the at least one leveling actuator to automatically level the plurality of sections of the harvesting assembly when in the second mode.

Abstract: A float arm support system may include a float arm supporting an active member, the float arm being pivotable about a first axis, a skid shoe to bear against and follow local ground contours of the underlying terrain while supporting the active member of the float arm above the underlying terrain and a powered actuator. The skid shoe may be coupled to the float arm between the first axis and the active member. The powered actuator may be operably coupled to the skid shoe to vertically move the skid shoe to adjust a spacing at which the skid shoe supports the active member of the float arm relative to the underlying terrain.

Abstract: An agricultural harvesting head for an agricultural harvester has a constant force assembly that changes the mechanical advantage of a spring applied to the mainframe of the agricultural harvesting head. As the mainframe of the agricultural harvesting head moves up and down on the front of the combine feederhouse, compressing and decompressing the spring, the constant force assembly changes the mechanical advantage of the spring such that the spring provides a relatively constant lifting force to the mainframe of the harvesting head as the mainframe moves up and down.

Abstract: An agricultural harvesting head has three frame sections. Each frame section is pivotally coupled to its adjacent frame section by two links. The two links are pivotally coupled to the two adjacent frame sections at both ends of each link.

Abstract: An agricultural harvesting head for an agricultural combine has a first gauge wheel assembly coupled to a laterally extending frame that is convertible from (a) a harvesting position in which the first gauge wheel assembly supports the frame during crop harvesting, to (b) a transport position in which the first gauge wheel assembly supports the at least one section for transport on the road.

Abstract: A corn head row unit gearbox includes an input shaft, that rotates about a first axis of rotation and that drives a set of bevel gears. The bevel gears transfer rotation of the input shaft into rotation of a set of gathering chain output shafts about a second axis of rotation, generally transverse to the first axis of rotation. The gathering chain drive shafts each rotate within a bushing mounted within a frame structure of the gearbox. The frame structure defines a bore that communicates with a bevel gear cavity, in which at least one of the sets of bevel gears rotates, and an interior of the bushings mounted on the gathering chain drive shafts. Rotation of the bevel gears carries lubricant to an inlet aperture on the bore and drives the lubricant through the bore into the bushings.

Abstract: A hinged row crop harvesting head (100) has two frame sections (110, 112, 114) coupled together with at least one hinge (186, 188) that permits the two frame sections (110, 112, 114) to pivot with respect to each other as the hinged row crop harvesting head (100) travels through a field harvesting crops.

Abstract: An auger conveyor (104) is provided for a row crop harvesting head (100) that has a hinged frame (102). The auger conveyor (104) has a first section (122) that is coupled to a second section (120, 124) with a universal joint (130).

Abstract: A row unit (10) for a cornhead comprises a frame (12), a pair of stalk rolls (14) and a pair of stripper plates (16) forming a stripper gap (20). At least one of the stripper plates (16) is a shiftable stripper plate (16) that is shiftable in a horizontal direction transversely to the longitudinal extent of the stripper gap (20). A spring (32, 32?) has a central helical part (34) winding around a pin (40) connected to the shiftable stripper plate (16) and outer end parts (36) abutting a respective one of two members (44, 54) connected to the frame (12) on opposite sides of the pin (40).
