If I remember correctly, there are 4 threaded studs or bolts that point up under the plastic covers on the top of the deck. There was not a single nut on any of the studs.
I wasn't sure if that would be a factory issue or a dealer setup issue.
If I get 250 hours without another problem I will be happy. I just pray I didn't get a lemon.
Thats exactly what happened. I felt a vibration while mowing and caught it before the nuts backed off. The nuts loosening caused the pulley to wear.
