HARVESTING MACHINE FRAME Abstract of the Disclosure A self-propelled windrower has a traction unit that includes a generally horizontal subframe in the form of a regular traphe- zoid, the subframe including transverse front and rear beams and a pair of rearwardly converging side beams connecting the opposite ends of the front and rear beams. The rear beam has a central fore and aft pivot, which carries an oscillating rear axle struc- ture that includes a pair of caster wheels at opposite ends of the axle structure. A pair of drive wheel support housings extend downwardly and forwardly from the opposite ends of the front beam, each housing including a vertical plate that forms the outer housing side wall, the upper end of the plate abutting and being welded to the end of the front beam and also overlapping and being welded to the outer side of the forward end of the side beam. The inner vertical wall of the housing is welded to the under side of the beam a short distance from the end of the beam. A hydrostatic wheel drive motor is rigidly attached to the lower end of each wheel support housing, the respective wheel motors being directly connected to the front drive wheels for the wind- rower. A harvesting header is supported forwardly of the frame for vertical adjustment relative thereto by means of a pair of vertically swingable fore and aft links respectively pivotally connected to the opposite wheel support housings on transverse pivots mounted on the forward sides of the housing adjacent the upper and lower ends thereof.
