Abstract
A rotary conditioning header has upright end panels that project forwardly from opposite ends of the rotary cutter bar. A top panel structure spans the end panels across their upper ends to define a crop receiving space between the end panels and beneath the top panel structure that is open at the front to define a mouth into the header. An upright rotary shear on at least one of the ends panels is located within the crop receiving space at the edge of the mouth but is exposed at the front such that its forwardmost cutting extremity is generally aligned with but underneath a transverse lean bar across the front edge of the top panel structure. The rotary shear severs and separates tangled crop stalks in the vicinity of the end panel to enable the stalks to be properly acted upon by the lean bar and received into the mouth.
