Consider getting low cost UV light leak detection system. You add a UV dye to the crankcase oil.
Clean the area around starter very clean using something like Brake Clean.
Run the engine a few hours and then park in a dark spot.
Use the kits UV flashlight to see if any traces of the dye color you put into the crankcase appear where your leak is,
No sign of your dye then add a different color dye to transmission. Repeat.
Is tractor sitting outside and water is getting into bell housing around the clutch. A little oil will float on top of the water.
Check the drain hole or holes in the bottom of the clutch area.
Local autoparts places are good starting points for a UV kit with dyes for cool and, dyes for oil etc. They began life for AC systems but have broadened their uses since.

I had a similar problem with my B7300 except it was leaking diesel from the starter. I posted video here of the leak. What I ended up doing was loosening the bolts that you would take out if you were going to separate the tractor. When I did about a cup of fuel drained out. I let it sit over night and all the next day, with the bolts loose, until I got home from work. I tightened the bolts back up and haven't had a problem since. I never found out where the fuel came from and it never happened again. I've used the tractor quite a bit since that time.
