L3540 - Trying to identify leak

[Jasbo]

I was using my tractor for the first time in an extended period of time and discovered a leak. I have identified the leak with a red arrow. If you can help me identify which system this is in, I will delve in farther in the manuals and forums, I just am too ignorant to figure out where to start. I greatly appreciate any help.

Your picture didn't show up, so the arrow is not visible!!

Can you clean the area as if you were going to eat off of the iron? Spray some Purple Power or something similar and spray it with a garden hose. Be sure it is dry and use a paper towel if necessary to wipe off dirt or water. Then run the tractor for only a couple of minutes to see if something appears. If nothing run for a longer time until you see what is getting damp.

Ty, I saw my mistake with the picture and was correcting it when you replied. I will clean the area as you have indicated. If/when the leak reappears, would there be a more helpful photo I can produce?

I think that pin your arrow is pointing to is like a "nail". It has a piece on the inside which restricts the hole. It often times has a spring to hold the pin in place, sometimes not. It is to let oil/fluids out from the inside and keep dirt from coming inside.

How much fluid do you think is draining?

Check the oil levels. If it's overfull it could just be 'burping'.

Clutch housing drain by the looks of it.

Looked at a similar tractor that was a hydrostatic where oil was leaking out from that hole. Was a main seal on the transmission side.

That is a weeping drain, it's job is to let condensation out of the clutch housing.
If your getting hydraulic fluid out of that drain most likely cause is its the 4wd propeller shaft seal is leaking.
It requires you splitting the tractor to fix it.

I had that problem with one of my tractors. Kubota repaired it as a known issue.
