Cub 7260 leaking fluid from Aux Hydraulic Valve

I am losing fluid from the auxiliary (remote) hydraulic valve at the rear of my 2000 Cub Cadet 7260 compact tractor, just above the PTO shaft under the PTO shield. At least I think this is what it is. It is a cylinder surrounded by ball bearings. Normally I believe that there was a cover of some sort that covered this valve since I never noticed it before fluid began spewing out. I checked my transmission dip stick and it was low, so I assume the fluid was the transmission/hydraulic fluid I was losing. Any ideas on what may have happened and how I might fix it?

Thanks in advance,
JimS

Sounds like you're describing a female quick-connect coupler. There are various types and they do go bad. Replacements couplers and o-rings are usually in stock at most dealers.

If this is a rear valve controlled circuit there should be two hoses with quick-connect couplers. I don't know if you've ever used the circuit but it's important the hoses to the implement are fitted with compatible male couplers.

If nothing were attached, I wouldn't expect much leakage unless the valve was operated when the tractor is running. If the couplers are good they would hold pressure and a relief valve would open and squeal. The valve has to be operated in both directions to test both couplers. The valve should be operated in both directions after the tractor is shut down to relieve the pressure or it's difficult to attach hoses. When nothing is attached, rubber dust covers should be used but they wouldn't prevent oil leaks
