ABSTRACT:
A pulley/belt drive system attached to a mower deck has a belt tensioning mechanism for maintaining tension in an endless belt. The belt tensioning mechanism includes an idler arm pivotally mounted with respect to the mower deck such that the idler arm pivots about an idler arm pivot. A back-side idler pulley engaging a back-side portion of the belt and an inside idler pulley engaging an inside portion of the primary belt are rotatably mounted onto the idler arm. A belt tensioning device is attached to the idler arm to pivot the idler arm, wherein the back-side idler pulley and the inside idler pulley remain in a fixed orientation with respect to each other when the idler arm is pivoted.
