What causes a hydraulic leak in a tractor?
Luckily, tractors have relatively small hydraulic systems and few hydraulic components. So there are not many places for hydraulic fluid to leak from. Gravity, vibrating parts, dirt and debris all combine to mask the origin of hydraulic leaks. You may find that the tractor hydraulic line that drips may not be the source of the leak.

What should I do if my hydraulic pump is leaking?
Reseal leaking fittings on hydraulic components. Unscrew the fitting from the component with a wrench. Remove and replace O-rings or other seals on the fitting. Then screw the fitting back onto the component. Replace the components you may be unable to reseal, such as the tractor’s hydraulic pump.

Especially frustrating can be the effort to repair these leaks, only to realize a short time later that you did not stop the leaks, you only slowed them down. A 420U (utility) owner who lives not far from me sent his tractor through a John Deere dealership to have the rockshaft leak areas repaired.
Where is the oil line on a John Deere tractor?

How to troubleshoot a John Deere hydraulic pump?
As you check the oil, make sure that the reservoir air vent cap is plugged. Low system-pump oil flow may be as a result of air leaks in the pump inlet line and fittings. If this is the problem, you should replace the parts as and when necessary. Check the relief valve to see whether it is partially left open and close it in case it is open.
