A power conveying system for use with a header of an agricultural harvester, the header having a first structural member and a second structural member being pivotally coupled to the first structural member about an axis. The power conveying system including a driving pulley, a driven pulley, an idler pulley, a flexible link and a cantilevered member. The driving pulley is coupled to the first structural member, and the driven pulley is coupled to the second structural member. The flexible link conveys power from the driving pulley to the driven pulley, and is in contact with the idler pulley. The cantilevered member is connected to the second structural member, and extends beyond the axis, where the cantilevered member is movably coupled to the idler pulley.
