My 3 year expierence with my 54 inch Raptor was good until recently. I didn't have belt issues until both the front and rear left hydro support brackets broke. All videos I've seen deal with the left hydro...why? The beefier set from Amazon should help with that. The other issue that cropped up was at the 200 maint scehdule. After completing that, the right hydro oil filter started leaking where it meets it's base. I did manage to tighten it a bit more past recommend tightening, but it's still leaking. i was just trying to deal with the leak during prime mowing season, but now have a chance to deal with it. i'm leaning towards a defective hydro gear filter, unless someone has had this issue also. If issues continue adding up, I may have to consider going back to Scag. However, I don't know if their manufacturing has gone downhill as well.
