TroyBilt does not have a service manual and I doubt if pictures are going to help much, as you can't see much. I have replaced these belts and I don't know what you mean by "It can't be that hard". Nothing is that hard if you know what you are doing and what to look for. In this case I'll give you a few tips, with a warning, have an assistant. Deck must be removed. Both belts are under tension and fingers can get pinched if not careful. Remove tension on both belts as your first step. To remove the bottom belt, you must loosen, do not remove, the sheave pulley assembly. This will allow you to get the belt past the frame, which acts as a belt guide. tighten the sheave pulley assembly after installing the bottom belt, then install the top belt. When both belts are installed put the tension back on both pulleys. Takes me about 45 minutes if I don't get interrupted. Good Luck if you are going to attempt this.
