Only a suggestion.

I had trouble with a mower that was throwing the belt... that is why I got it for next to nothing.

Putting a Gator Back Premium belt solved the problem...

Guess not all belts are created equal... the notched design allows for greater variance.

May or may not be applicable.

I heard those gators are really worth it.

Very similar looking. My deck has a shoulder bolt there which CC customer Doppler said was an add on to keep the belt running true. It was not...on my model...equipped with a pulley.
Customer support is pretty sure the problem is the pivot on the idler. I ordered a few new parts to fix it. I'll let you know how it works out.

That's all mine has is a shoulder bolt, not the whole pulley like on the picture,
But that was the fix

I apologize but I can't get the picture today as we had a rare nor Easter that is dropping snow and rain like crazy and my deck
Is outside. When the rain stops I'll remove the covers so you can get a good view of the entire pulleys and belts

Here they are.
I do have an extra heavy duty spring that I installed on there.

I think I'm going to add a heavier spring, too. I was quite surprised at the light pull on this.

If you need one of those springs let me know, it would just cost you just shipping.

Thanks for all the help and input on my problem. I ordered a new idler arm and bolt, and another member here sent me a heavier idler spring. The combination has solved the belt throwing problem.
While I had the mower off, I noticed that the universal joint, where it attaches to the mower's gearbox, was very loose. The U-joint is held to the box's input shaft by a snap ring and is bolted through. The hole on one side of the U-joint was much larger, I suspect for a special bolt which would apply pressure to the shaft. I had some spacers that fit and when I tightened it up it took the rattle out of the joint--and it runs true--or appears to. It seems to have taken some vibration out of the mower.

One thing I notice bout the vibration is that , at least on mine, the shafts are only balanced one way,
Mine used to vibrate, and I tried it all 4 ways to I found the one that took out the vibration.
Once I did that , I marked the two sides so it would always go back on the same way

I am speaking about both sides of the half shafts of I confused anyone

Actually, I knew just what you meant.
