Abstract
A header includes a substantially rigid header frame having a main longitudinal rear tube and a plurality of beams extending downwardly and forwardly from the main tube to a cutter bar which is maintained substantially straight and parallel to the main tube. Adjustment of the longitudinal shape of the cutter bar is effected after the header is assembled by operating screwjacks on two inner beams which cause plastic bending of the beams to raise or lower a center portion of the cutter bar so that when assembled the cutter bar is longitudinally straight or slightly upwardly concave. This adjustment after the assembly is complete allows the cutter bar to be adjusted to the required longitudinal shape for optimum cooperation with the reel.
