Abstract
The floating cutter bar (37) of a harvester is mounted on the header by a series of laterally spaced parallel linkages (60). The cutter bar (37) is counterbalanced by the combination of compression springs (104) acting on the lower link (62) of each linkage (60) and overlapping sheet springs (111, 112) which also serve as an access ramp for harvested crop. The front ends of the links (61, 62) of the parallel linkages (60) are connected to the cutter bar skids (41, 43, 45, 47) by ball and socket joints (71, 76 and 72, 77).
