Additional Information
This blade idler pulley (part number 532173437) maintains tension on the mower deck belt, allowing smooth engagement and consistent rotation of the cutting blades.
If the belt slips, squeals, or the blades fail to spin evenly, a worn or seized idler pulley may be the cause. Replacing it helps restore reliable cutting performance.
Let the engine cool and disconnect the spark plug wire before beginning the repair. Wear work gloves to protect your hands during installation.
532173437 replaces part numbers 5321658-88, 532165888, 173437, and 165888.

Easy to Install
I tried another supplier and there's was to small, was able to return it to that supplier. For the DIY's you will have to put something like a screw driver between the head of the bolt and the Deck so you can un-thread the Nut without damaging it.

Confusing shipment
I ordered the pulley, bolt and nut at the same time and paid for them at the same time. I was very surprised when the bolt arrived without the pulley or nut. A check of the shipment showed that the pulley and nut were with the post office for delivery. The pulley and nut showed up the next day. Why can't all 3 items that were ordered at the same time and paid for at the same time ship together in one package?
