For the requirements you have for a mower. I would not go to TSC. I would find a dealer I could trust and see what their recommendations are. I would fix that Hustler before I bought a Bad Boy. On some of the Hustlers hour meters were an option. The tranny may be able to be rebuilt. I would certainly get a second opinion from the one you have gotten.
