618 grasshopper rt. side hydrostat

[dlt1945]

my 618 grasshopper will not go forward on the rt. side (just hear a winning sound) when I push the rt steer lever forward, However when I pull the lever back the reverse works fine. Does this mean that the hydrostat is junk or can it be repaired with new seals? Can a rebuilt unit be purchased?
Any input would be helpful.
thanks Dave

Big Daddy, thanks for your reply,I did get my hydrostat repaired, The problem was that a bolt in the check valve had come loose and let the ball open up. I probally could have repaired the valve without removing the hydrostat from the mower, but I am very happy to have gotten it fixed very fast and at a reasonable cost
