Abstract: A cover assembly for a knife drive of an agricultural header includes a cover having a channel configured to receive a drive arm of the knife drive. The channel faces upwardly with respect to a vertical axis of the agricultural header, and a lateral extent of the channel is configured to enable the drive arm to oscillate to drive a blade support of a cutter bar assembly to oscillate. Furthermore, the cover has a front section and a rear section, the front section extends upwardly and rearwardly from a front end of the cover to the rear section, the rear section extends continuously downwardly and rearwardly from the front section to a rear end of the cover, and the rear section is configured to be angled less than 45 degrees relative to a longitudinal belt of the agricultural header.

Abstract: A corn harvester that includes a corn head including a plurality of dividers. Each divider includes a top surface, first and second side surfaces, a proximal end and a distal end. One of the first or second side surfaces includes a recessed area formed therein. The corn harvester includes a tall corn attachment mounted to the hood and configured to be positioned in a stored position or a working position. In the stored position, the tall corn attachment is received within the recessed area of the hood. In the working position, the tall corn attachment extends from the top surface of the hood. The tall corn attachment includes a latching mechanism for locking the tall corn attachment in the stored position or the working position.

Abstract: A row unit of a corn head assembly for an agricultural harvester capable of reducing grain loss is provided. The row unit includes a frame and first and second spaced apart row unit arms mounted to the frame, and a top plate. The top plate is positioned about a rear end of the frame and includes an outer surface having a retaining structure configured to inhibit a flow of grain in a forward direction along the outer surface.

Abstract: An example corn harvester and associated systems and methods are provided. The corn harvester includes a corn head including a plurality of dividers. Each divider includes a top surface, first and second side surfaces, a proximal end and a distal end. One of the first or second side surfaces includes a recessed area formed therein. The corn harvester includes a tall corn attachment mounted to the hood and configured to be positioned in a stored position or a working position. In the stored position, the tall corn attachment is received within the recessed area of the hood. In the working position, the tall corn attachment extends from the top surface of the hood. The tall corn attachment includes a latching mechanism for locking the tail corn attachment in the stored position or the working position.

Abstract: A corn head assembly for a combine harvester capable of reducing grain loss. The corn head assembly includes a frame, a plurality of row units and a hood. The frame is mounted to a forward end of the combine harvester. The plurality of row units extends forward from the frame. The hood extends between an adjacent pair of row units. The hood includes a first end proximal to the frame, a second end distal to the frame and opposite the first end, and an outer surface extending between the first and second ends. The outer surface has a plurality of structures configured to inhibit a flow of grain in a forward direction along the outer surface.

Abstract: A row unit of a header for an agricultural harvester having a gathering chain lockout assembly is provided. The row unit includes a frame, a gathering chain assembly and a lockout assembly that allows adjustment or removal of the gathering chain. The gathering chain assembly is mounted to the frame extending forwardly of the header and includes first and second sprockets, an endless chain extending between the first and second sprockets, and a carriage assembly extending from and supporting the first sprocket. The carriage assembly has a stationary member and a moveable member moveable relative to the stationary member between an extended position and a retracted position. The lockout assembly is attached to the carriage assembly and includes a lockout fastener pivotably attached to one of the stationary member and moveable member and an engaging member attached to the other of the stationary member and moveable member.
