Abstract
A draper platform includes a drive roller and an idler roller spaced from the drive roller. A belt is operatively coupled to each of the drive roller and the idler roller. The draper platform also includes a belt tensioning system, including a tension adjustment rod. A worm gear is operatively coupled to the tension adjustment rod. A sector gear is in meshed engagement with the worm gear. A push rod is operatively coupled to each of the sector gear and the idler roller such that rotation of the sector gear causes translation of the idler roller so as to adjust tension of the belt.
