ABSTRACT:
A chassis for a self-propelled agricultural machine adapted to travel in a predetermined longitudinal horizontal direction basically comprises a lower frame, a middle frame spaced above the lower frame and offset somewhat therefrom, and an upper frame spaced above the middle frame and offset horizontally therefrom. The lower frame has a pair of longitudinally extending rigid lower side beams having outwardly offset rear ends and a plurality of longitudinally spaced and transversely extending lower cross beams fixed to and bridging the lower side beams. The middle frame has respective transversely spaced front posts fixed to the lower side beams, respective transversely spaced rear posts fixed to the lower side beams behind the front posts, respective middle longitudinal side beams fixed to the upper ends of the respective posts above the lower side beams and having front ends projecting forward of the front posts relative to the travel direction, and respective front and rear middle cross beams fixed to the middle side beams and projecting transversely beyond the side beams. The upper frame has respective transversely spaced upper front posts extending up from the middle side beams, respective transversely spaced upper rear posts fixed to and extending up from the middle side beams behind the upper front posts, respective upper transversely spaced upper side beams fixed to the upper ends of the upper posts and projecting forwardly beyond the front upper posts, and respective upper longitudinally spaced front and rear cross beams extending between the upper side beams.
