   Ok to start off with im an automobile tech and don't have a lot of experience with the internal workings of this tractor so im hoping someone may be able to guide me to a repair manual I can purchase? I have the jensales parts manual already so any help is always appreciated! 

Here is my issue it has the hydraulic drive system and over the last month I have been having to push the pedal farther and farther to get it to move now if you put it under stress like a hole or something it will not go it acts like a clutch is going out.  So knowing its a hydrohalic drive system is there an adjustable clutch of some kind?  Could the pump that runs the drive be failing? fluids look good we recently replaced the accessory pump and steering pump because we lost steering do to internal pump failure.  thanks for any advice or guidance you can offer.
