I am trying to get my old Troy-Bilt Model 609 42" mower going again. I quit using it several years ago because the PTO belt would not engage properly even with a new belt. When I check the belt tension, it doesn't seem to tighten much at all when I engage the manual PTO. I'm getting ready to remove the deck to try to figure out what is wrong, and thought I would ask for suggestions on what to look for. Here is the diagram of the belt:

When I last looked at it, the pulleys seemed OK, but engaging the manual PTO would just not tighten the belt enough to engage. I seem to recall there was some interaction in the adjustments for the belt tension and brakes, and I suspect the last mechanic may have adjusted them incorrectly. I remember he said something to me about installing a longer bolt to solve the problem, but that did not help. That bolt is labeled in the second image. I think that is the bolt that connects to the cable that connects to the PTO lever. When I removed the deck the last time, I couldn't see how the "long" bolt would have accomplished anything.

What I have considered, if all else fails, is to add an additional idler pulley as shown in red in the second image. I suppose it would be better to try to get it all working properly, but I'm not above jury rigging something if necessary.
Thanks,
Charles
