I bought my first Gravely yesterday. It is a model L I. It has a 30" mower deck and a sulkey. The sulkey looks to be home made. I am not familiar with Gravely's at all as this is my first. The tank is rust free, but has gunk that looks like it will clean right out. Kinda jelled gas at the bottom. The guy said it's been sitting for about 12 years. I haven't even tried to turn the engine over yet. I ran out of time the other day. What would this model with the deck and sulkey be worth? I think I did ok, but want to be sure. Here are some pictures.
