Is your John Deere mower deck making a squealing noise or the belt keeps coming off? A worn idler pulley is a common culprit. This is a Caltric replacement flat idler pulley, part number AM135526 (also fits PY226A1001). It's made of aluminum, has a 17mm bore for the shaft, and the pulley itself is about 132.5mm wide and 30.5mm tall. Brand new with a 90-day warranty. Fits various John Deere riding mowers and lawn tractors that use this specific pulley on the deck. Replacing a seized or wobbly pulley is a pretty straightforward repair that can save your mower belt and get your cut quality back to normal. Always compare it to your old, removed pulley to be sure.
