Abstract: A stalk roll for an agricultural harvester row unit comprising a plurality of longitudinal extending knife edges about its circumference, in which one of the leading and trailing sides of the knife edges is coated with a first wear resistant coating over substantially its entire length, and in which the other of the leading and trailing sides is coated with a second wear resistant coating over at least one of a front portion thereof and a rear portion thereof.

Abstract: A row unit for an agricultural harvester includes left and right row unit arms that are fixed together with the shaped support. The shaped support is bent to extend across the top of the row unit arms and down the outside vertical surfaces of the row unit arms. The shaped support is welded to the outside vertical surfaces of the row unit arms.

Abstract: A row unit comprises a row unit gearbox with two shearing edges and two stalk rolls with corresponding shearing edges, wherein the stalk roll shearing edges shear against the gearbox shearing edges when the stalk rolls rotate during normal operation of the row unit, thereby chopping material that might otherwise be wrapped around the row unit gearbox and be jammed between the stalk rolls and the gearbox.

Abstract: A row unit gathering chain has a number of links that is an integral multiple of the number of teeth on the sprocket on which it is mounted.

Abstract: A combine head trough assembly comprises a curved steel panel having two openings passing therethrough, one opening being disposed at each end of the panel, the assembly further comprising two doors configured to respectively cover the two openings. The doors are pivoted between a closed position during normal combine operation and an open position to permit cleanout of crop material.

Abstract: The invention comprises a point and cover assembly for a row crop header including a point; a cover coupled to the point with a hinge; a latch fixed to the cover, the latch having a first spring-loaded latch pin for pinning the cover to a first row unit, a second spring loaded latch pin for pinning the cover to a second row unit, and a member coupling the two latch pins together that is operable by one hand to release both latch pins; and a point support fixed to the cover, the point support comprising an elongate member fixed at its rear end to the cover and having an adjustable point rest at its front end for supporting the point at a plurality of different heights.

Abstract: A harvesting reel is rotatably mounted on left and right saddles. The saddles are slidably positioned on fore/aft extending arms. A fore/aft position sensor is located between one of the fore/aft extending arms and the respective saddle. The fore/aft extending arm is provided with a slot that extends along the arm at an angle thereto. A sensing finger engages the slot and is coupled to a potentiometer by a sensing arm. As the fore/aft position of the reel changes, the relative position of the sensing finger changes creating a changing electrical output from the potentiometer. The resulting potentiometer voltage represents a fore/aft position signal that is directed to a controller.

Abstract: A ground contact height sensor for a harvesting header comprises a transverse rotatable shaft, a first rigid arm, a second rigid arm and a connecting member. The rotatable shaft is rotatively mounted to the frame of the header. The first rigid arm is rigidly mounted to the rotatable shaft. The first arm extends downwardly and rearwardly from the rotatable shaft in a curved manner. The second rigid arm is pivotally coupled to the first rigid arm by a hinge joint. The second rigid arm extends upwardly and rearwardly from the second end of the first rigid arm. The first and second rigid arms defining a relatively large radius. The connecting member secures the rearmost end of the second rigid arm to the frame of the header. To maintain the radius of the two pivotally connected rigid arms the hinge joint joining the two rigid arms is provided with a torsion spring.
