The cutter bar of a header including two sickle bars is driven by a center drive system including a rotary input drive member driven by a motor, first and second rotary members each driven by the drive member about a generally upstanding first rotational axis. Each of the rotary members has an eccentric drive system for driving a respective sickle bar. A flywheel is driven by the rotary input drive member for common rotation therewith and the first and second rotary members are driven by a common drive sprocket to rotate in the same direction about the first and second rotary axes.
