You may need to look into the deck mounting - draft arms, pins, etc to make sure it allows deck to sit & cut level and not bounce around. I recall one I had trouble with that was doing the same thing - everything looked great but it kept tossing belt and bending guides, etc. Finally I removed the blades from deck and had my dad sit in tractor and operate PTO and raise/lower deck while I tried to shift things around, then I realized that it was the worn-out deck mounting (draft arms holes worn oblong, mounting pins, which were replaceable, had slots worn into them from draft arms, and so on) after getting customer approval on estimate (which was expensive - I think the guy had more money than brains.. That or he was too emotionally invested in the color & logo) I replaced all the deck mounting stuff and adjusted deck level, cleaned & lubricated or replaced every single worn out pivot bushing on the deck (or the component it pivoted on) and got a new belt guide, which I had thought was bent out of shape , but new one was the same shape as old one... figured out how it mounts (belt loops up and over the outer prongs and inside edge of belt just clears the inner bracket, if I recall right) but once we threw all that moolah into it, he ran that tractor for the next 4 to 5 years with no trouble other than having me do annual maintenance. (until he dropped dead of a heart attack or something.. don't know what heirs did with the machine after, but I figure it probably went on some junk pile - the deck was nearly rotted out entirely and rest of machine looked totally roached)
Long story short, I think I may have had a similar tractor & problem, solved by getting creative as to how to observe the machine in operation safely and *see* what was happening.
