Billy Goat Idler Pulley

Because fitment varies significantly between different Billy Goat models, we recommend checking your owner's manual or the parts diagram for your specific machine to verify the part number. This pulley has an outer diameter of 4.5 inches, which is a key specification to cross-reference against your current component.

Common indicators include excessive vibration, a squealing or grinding noise coming from the deck area, or visible wear on the pulley's groove. If you notice your mower belt slipping frequently or showing uneven wear, the idler pulley is often the culprit.

This replacement pulley is constructed from robust iron. This material choice provides superior durability and heat resistance compared to plastic alternatives, ensuring it can handle the consistent tension required for lawn maintenance.

If you are comfortable with basic mechanical repairs, this is a straightforward replacement. You will generally need standard hand tools to release the belt tension and remove the mounting bolt, but always consult your mower's service manual for the specific procedure to ensure safety.

No, this listing is for the idler pulley component itself. You should reuse your existing mounting bolt and spacers, provided they are not damaged or worn.
