I am in the middle of changing the hydro drive on my Cub Cadet. Has about 35 hours on it and it lost its forward motion once it was warmed up. The dealer wanted almost as much to repair is a new one. I decided to see if I could do it. I found a new drive on line from the factory and just started pulling the tractor apart. I should be done this weekend. I cant help on your specific model, but good luck.
