Probably going into trans/rearend. I would check the levels.

Probably the tin pan between the rear and rockshaft is leaking as olliejunkie said, its probably going into the rear.

Not sure but I think there is also a seal that fails in there.

It's going into the rear end, but that's pretty fast...20 minutes. Must be a big leak in pan or a seal as others have said.

Draft control I think goes through the pan also I was thinking too. Could be front pump seal or pump mounting also. I'd pull the PTO and see where the oil is leaking from.
