Is the idler pulley on your John Deere mower worn out or squeaking? This is a direct, heavy-duty replacement for the OEM part AM128118. It's made from corrosion-resistant steel with a zinc plating to fight rust, and it has a sealed bearing to keep dirt out. It fits a ton of John Deere ZTrak zero-turn mowers (like Z245, Z465) and lawn tractors (like GT225, LX255, LX266, X324, GX355) – check the full list to confirm your model. The dimensions are: about 4.71\ outer diameter, 0.67\ inner diameter, and 1.25\ height. Installation is usually straightforward – just swap out the old one with the same bolts. A simple fix to keep your mower's belt tension correct and running smoothly.
