Joe Bruner 1 #1 Posted 11 hours ago I have a 520-H 3120OEO1 and the deck is rear discharge 36MR01-17452. There are a few digits in front of the 36 but they are under the frame. I’m trying to find the belt from the PTO to the mower deck. The parts store tried to look it up but the belt they sold me is too long. Any help would be appreciated.

gwest_ca-(File Mod) 12,223 #2 Posted 10 hours ago The first model digit is the one that would determine the model year or years. The 2nd missing digit is 5 for mowers. This may not be the exact model you have but the belts should be the same. Click on the fuzzy mower decks. The belts are listed on the page that comes up.
