Does this part fit my model?
Need help finding your model number?This 5-inch flat idler pulley guides the back side of a V-belt and helps maintain correct belt tension and alignment. It is used in deck and drive systems on select zero-turn and stand-on mowers. A worn bearing or damaged pulley can cause noise, belt wandering, uneven tension, or early belt wear. Inspect the belt, idler arm, spring, spacer, and mounting hardware during service. Confirm the equipment model, serial number, pulley diameter, bore, height, and mounting arrangement before ordering. This is a genuine OEM part sourced from the manufacturer directly.
