Leak near base of Joystick

[LouieJunior]

I noticed a lot of oil near the joystick. From the rear, it looks like the control unit is missing a cover or cap. Would this be the likely source?
Thanks!

There are no caps missing, as there is a cap for each spool on the two spool valve.

The third item over is probably the relief valve for the open center hyd system on your tractor.

If you have a leak from the bottom of the valve, you might have some o-rings that can be replaced.

You normally can not replace spools in a valve when they wear as they are a precision part.

Soap it up and clean it spotlessly clean and then search for leaks. If it's clean, it will be much easier to spot the exact source of the leak.
