ABSTRACT:
A crop harvesting header includes a center portion mounted on two spring arms and two separate wings pivotally connected to the center portion. The wings are connected to the center portion by interconnecting linkages which transfer weight from the wings to the spring arms each including a balance beam arranged to balance the lifting force from the spring arm with the downward forces from the center portion and wing such that the downward force on a skid plate of each portion on the ground varies automatically as the total downward force is varied. The balance beams apply force to the linkages by a compression member to reduce forces. The movement caused by floating of the header and the change of angle of the header are compensated at the balance beam to ensure that the force to the wings is reduced as the requirement caused by changes in geometry reduces.
