Check your belt tensioner or your rear pulley could have a peice of debris stuck in it.

You also might want to check and see if the pulley's are straight. The bolt could be loose and the pulley is wobbeling. When was the last time you changed the belt?

Here are some possible causes, any of which could require a close inspection:

1. The belt has a cut or a piece missing somewhere.
2. A bearing in one of the pulleys is gone or going.
3. A pulley is loose because the nut / bolt isn't tight.
4. A pulley has a dent in it.
5. The belt is loose or stretched.
6. Wrong belt, perhaps more so if it was recently replaced.
7. Oil or some other lubricant has contaminated the belt.
8. Dirt / debris was mentioned earlier

I'm sure there are more but I'm also pretty sure if you check out everything
along those lines you should hit upon it.

My pto belt kept popping off when I started the mower deck. I replaced the belt and no problems sense.

You might have to take it to the dealer if you don't know
how to check for bad bearings and what have you...

I can't say for sure, it's not my mower but I dare say it's a safe bet that
warrants further checking... I can't guarantee that what you're describing
is your problem without physically looking at the machine, but I can recommend
that you look further into that there double pulley issue.

As in, it could very well be the problem, but I have no way to say with 100% certainty,
however I can tell you that pulley shaking / vibration / movement during operation
more than certainly can be (and is) responsible for tearing up belts and such.

So, I'd look further in that direction, at least for now we have it narrowed down.

The spindle sounds like it went out. Also check to see if the blade is balanced.

the double pully doesnt have a blade under it its one of the pullys that move like to get the belt on easier

It sounds like the tenching pulley. Check the bolt that holds the bracket to the deck. If not then the pulley could be bent or the bearings are shot.

when you reply there is a paper clip in the options above where you write. That will let you add a picture.

tIt shouldn't be the problem unless you bent the pulley. If the bolt i tight I would say the pulley is shot. The bearings and race couldhave seperated from the pulley. I would start with that. Also if you took it apart before, make sure you didn't forget to put a spacer or washer back on.
