Abstract
A basic frame for a crop harvesting header which is attachable to a combine to sever standing crop and initiate the crop harvesting process is disclosed wherein the same frame can be utilized in the construction of both rigid and flexible headers. A connection member is provided for each attachment rib interconnecting the frame and the cutterbar, such that the attachment rib can be either pivotally connected to the frame to provide a flexible header or rigidly attached to the frame to provide a rigid header. Each connection member permits a rigidly attached rib to be vertically positionally adjusted to provide proper alignment of the cutterbar across the entire width of the header. The header frame includes a hat-shaped member corresponding to each of the connection members within which the attachment ribs can be nested.
