Lawnboy 10685 won't self propel

I bought an otherwise good running lawnboy model 10685 push mower that is about 6 years old. However, I noticed that the even after tightening the drive cable, it still would barely self propel. Next, I replaced the trans belt, but this did no good either. I suspect that the drive pulleys are worn (it seems that the engine pulley is allowing the belt to bottom out). I can self turn the trans pulley and the wheels turn fine. Anyhow, at this point, do worn drive pulleys seem like the most likely culprit (and which one is more prone to wearing)? Finally, can someone give me a quick rundown on what is involved in removing and replacing these pulleys?

Thanks!

Let me see if I can narrow the question down; This seems to be equivalent to a Toro, so I am wondering if simply taking the blade off allows the easy removal of the pulley, or is there more to it? Also, on the drive end, does taking the locknut loose allow for the easy removal of that pulley, or does the entire drive assembly need to come off?

Same mower, did exactly what you have done and same result. The difference is I bought this mower brand new in 07' and the self propel has worked flawlessly until this year. It would drag you up a hill with a full bag. My guess is the pulleys, one or both? Did you figure it out


Thanks
