Abstract: A belt tension mechanism for tensioning an associated belt drive system on an associated vehicle is provided. The associated belt drive system includes a double stacked pulley, a first belt for providing power from a power mechanism to the double stacked pulley and a second belt for providing power from the double stacked pulley to an associated implement. A first tensioning mechanism is provided for tensioning the first belt and a second tensioning mechanism is provided for tensioning the second belt. A tension arm selectively simultaneously tensions the first and second belts from an inoperative condition to an operative condition or from an operative condition to an inoperative condition. A balancing mechanism is also provided for balancing tension on the first and second belts as the implement is selectively height adjusted.
