Lowes sell Troy Bilt and best place to look that I know of. During week they have someone in there lookup for you but never saw one.

Many Thanks for the tips. I'm learning more each day and will share as I progress. Just found out that all five seals on the transmission are shot so I'm biting the proverbial bullet and will open up the transmission to inspect the gears when I replace the seals. If the shims are installed with the tranny in neutral, I'm going to need about a dozen of the thick ones. That seems a bit excessive so I'm starting to suspect that I may have severe gear wear. More when I get it open. I may get to know Bill very well before this is over. ;-) Again, thanks.

TroyBilt went bankrupt a few years ago, and its assets were acquired by MTD. Present-day Troy Bilts are made by MTD. I understand that they are still supporting the old stuff. Go to the MTD web site and do a search. Also, if there is a local dealer who handles Troy Bilt, they should be able to help. Good luck.
