Mine also leaked in the line to the cylinder. made a mess under the tractor, all over the mower deck.
To answer the other question, you do NOT need to drain the fluid. Fluid loss is minimal, mostly what is in the hoses. I also strongly recommend replacing all 4. I went to the local Parker store (most metro areas have them) and they can make up any hose on the tractor. One of my steering hoses had a funny end, I believe it was a 45 deg swivel, which was not in stock. I got a straight end on the hose and bought a 45 deg M>F swivel to solve the problem. Also as I mentioned in another post, you can unbolt a bracket and drop the steering cylinder to get to the connections without any special tools.
