There are 2 potential problems -
1. Leaking spool on the control valve - rebuild the vale.
2. Cylinder blow-by. Disassemble piston and replace the seals.
To test if its the cylinder - retract the cylinders all the way... remove the hoses on the blind end (non rod end) of each cylinder, and again pull the valve to the retract position.
If fluid continues to pour out of the cylinder - the piston seal is damaged, and the affected cylinder must be repaired.
To test if the valve spool is faulty - disconnect the a and b ports just after the valve. Turn on the system and check for seepage from the disconnected lines (without moving the lever).

I have googled LT155 and came upon john deere LT155 lawn tractor(noncurrent). It took me to John Deere's site. I put in your model number and it had several catagories. I would try the alphabetical list, go to B and look for traction belt.
