It helps keep the belt aligned and supports smooth engagement of the drive system so power transfers efficiently from the engine to the tines. If the idler pulleys groove wears or the bearing fails, the belt can slip, make noise, or wear unevenly. You might notice reduced tiller performance, belt squeal, or vibration in the drive area if the pulley is worn or damaged. Stiff or seized rotation can also interfere with proper belt tension and reduce efficiency. Disconnect the spark plug wire or battery, depending on your tillers design, before starting the repair to prevent accidental startup. The pulley and drive area can have sharp edges, so wearing work gloves can help protect your hands during installation. Make sure the pulley is seated correctly and the belt tracks properly before using the tiller. Tiller idler pulley 756-0405 replaces part numbers GW-1724488, 756-0405, 1626-104, 1724488, and 1714742.
