Enhance belt tracking and drive reliability with AMTHKNOs dedicated kit that combines a precision idler pulley and a rugged belt designed for Toro TimeMaster 30 inch decks. This pair is engineered to work together, helping keep the belt path steady and the deck performing consistently across compatible models.

The kit centers on two components: the 131-4509 Mower Idler Pulley and the 120-3335 Belt. The pulley measures 2 3/4 inches in length with a 1 inch height, a 1.4 inch mounting hole, and a .7 inch inner diameter.

Used together, they aim to restore proper tension and maintain smooth belt engagement under typical mowing conditions.
