Cub Cadet 7304 PTO & Hydraulics

[Ditto]

Hi All,
I have a Cub 7304 tractor and here is the issue. I was cutting grass today (Rear Mount Deck) I hit a rock and the PTO immediately stopped, along with that I lost the Hydraulics (Both Steering and 3-point lift). I'm sure it's going to get very ugly and expensive. Anyone have any ideas what to look for?
Also where can I find a repair/service manual for this tractor.
Thanks in advance

Update:
I did find a manual and I will share with anyone who needs it. I've narrowed the issue to the output shaft on the hydrostatic pump/motor. I'm a bit shy on tearing this thing apart blind..But it doesn't work anyway so what can happen right? Any Ideas where I can get more Info on the pump? Thanks again
