I noticed my 2YO BX23 leaking fluid. It's coming from center, rear of tractor just above PTO drive. I'm guessing it's hydraulic fluid as it measured low and when I added more and turned on tractor a steady flow of fluid came out (it doesn't look like oil / gas). There's a casing and it almost looks like it's coming out of two screw holes (see attached pictures). This is probably beyond my ability to fix and I'll get it in for service, I just wanted to know what I'm likely dealing with. Thanks in advance.
