S P E C I F I C A T I O N S HEADER SUSPENSION AND LIFT MEANS ABSTRACT OF THE DISCLOSURE A crop harvesting machine has a crop harvesting header, a mobile frame and improved header suspension and lift means. The frame includes an upper transverse elongated member and a pair of spaced apart side members fixed to the upper member proximate its opposite ends and extending downwardly therefrom. A pair of wheel arms extend rearwardly from the respective side frame members and are mounted to respective lower portions thereof for vertical swinging movement about a generally horizontal transversely-extending axis. Each wheel arm has a ground-engaging wheel rotatably mounted thereto. The improved header suspension and lift means includes an upper link pivotally interconnecting an upper portion of the header to the upper frame member and a pair of elongated lower members respectively extending forwardly of the wheel arms. The lower members are pivotally mounted proximate the respective forward ends of the arms and have portions extending rearwardly and within the path of swinging movement of the wheel arms. Lift means in the form of a pair of hydraulic cylinders are mounted between the frame and respective wheel arms and actuatable for causing swinging movement of the wheel arms and the lower members therewith so as to effect upward lifting of the frame and header from a lower field operating position to a raised transport position.
