2-105 white leaking hydrolic oil into transmission

[Paul L M]

I plugged off the hydrolic lines to the pto control valve, filled the hydrolic reservoir i ran the tractor all day plowing, using the hydrolics the hydrolic reservoir stayed full. I then replaced all o-rings in the pto control valve hooked up the hydrolic lines and ran the tractor and immediately the hydrolic level in the reservoir started to drop. Do I need to replace the pto control valve?

PTO needs removed. Seals are bad or a cracked piston for pto brake.
