A header for a combine or the like having a cutterbar assembly which is vertically flexible relative to the main frame of the header. Leaf springs are fixedly connected to the header frame and extend forwardly to a sliding connection with the cutterbar assembly to exert a counterbalancing upward force thereon. Longitudinally reciprocable adjustment bars captive on threaded adjustment bolts are mounted on the main frame in association with each spring for varying the upward force being exerted thereby.
