Abstract: An intake tower for a work vehicle has a grille with a front face and a duct defining an internal volume and an air intake. The air intake has a periphery at which the grille is mounted and first and second ends. The first end of the air intake is closer to a region of relative low pressure within the internal volume of the duct than the second end. A partition extending between the first and second ends of the air intake is recessed from the front face of the grille. The partition defines one or more intake openings leading to the internal volume of the duct. The opening(s) or portion thereof define a first flow area at the first end of the air intake and a second flow area at the second end of the air intake. The first flow area is lesser than the second flow area, and the opening(s) or portion thereof defining the first flow area is located nearer the front face of the grille than the opening(s) or portion thereof defining the second flow area.

Abstract: An agricultural harvesting head comprises a frame, crop dividers located at each end of the frame, and a reel supported on the frame between the crop dividers wherein a disk at at least one end of the reel has a wiper mounted upon it that wipes against the surface of a crop divider as the reel and disc rotate during harvesting, and in this manner helps clear the crop divider of crop plants that might otherwise become hair pinned on the crop divider. Wipers can be provided on discs at both ends of the reel to thereby keep both crop dividers clear.

Abstract: A control system (210) is provided for an agricultural harvester (200), the agricultural harvester (200) having an agricultural harvesting vehicle (202) and a harvesting head (204) mounted thereon, the harvesting head (204) further comprising a left side endless belt conveyor (214) driven by a left conveyor motor (312), a right side endless belt conveyor (218) driven by a right conveyor motor (310) and a center endless belt conveyor (220) driven by a center conveyor motor (314), the control system (210) comprising an electronic controller (300) configured to receive an electronic signal indicative of a roll angle of the harvesting head (204), and to electronically change a relative speed of at least one of the right conveyor motor (310) and the left conveyor motor (312) based at least upon the electronic signal indicative of a roll angle of the harvesting head (204).

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 articulated harvesting head load sensor arrangement is provided that includes two harvesting head sections (102, 104, 106) that are coupled with a first pivot pin (162) that is a load pin.

Abstract: A draper platform (100) has a center endless belt conveyor (118) that is supported on and between first and second adjacent support arms (246A, 246B). The center endless belt conveyor (118) is releasable from a first support arm (246A) of the two adjacent support arms to pivot downward away from the first support arm of the two adjacent support arms a distance sufficient to slidably remove an endless conveyor belt (134) from the center endless belt conveyor in a direction parallel to the axes of rotation of the rolls (300, 302) that support the endless conveyor belt.

Abstract: A material chopper may include a counter shear bar, a plurality of stationary knives associated with the counter shear bar, a shaft, at least one rotor section operatively connected to the shaft, each of the at least one rotor section configured to rotate with the shaft, at least one knife holder in each of the at least one rotor section, at least one knife operatively connected to each of the at least one knife holder, and slots in each of the at least one knife holder, wherein edges of the slot provide counter shear surfaces for the plurality of stationary knives. The material chopper may be added to or incorporated into a harvesting machine such as a combine.
