HEIGHT CONTROL FOR A MULTI-SECTIONED CUTTING PLATFORM

摘要

An agricultural harvesting machine (10) includes a feeder housing (14) and a cutting platform (12). The cutting platform (12) includes a center platform section (16) carried by the feeder housing (14). A first wing platform section (18) extends laterally from one side of the center platform section (16), and a second wing platform section (20) extends laterally from another side of the center platform section (16). A height control system includes a lift cylinder (36) coupled with the feeder housing (14), a first tilt cylinder (38) coupled between the center platform section (16) and the first wing platform section (18), and a second tilt cylinder (40) coupled between the center platform section (16) and the second wing platform section (20). The lift cylinder (36), first tilt cylinder (38) and second tilt cylinder (40) are automatically adjusted independent from each other during harvesting operation of the cutting platform (12).
