Was planting soybeans earlier. Raised planter at the end of the row. Hit SCV to raise marker (they are separate) and it went about half up. Looked around and oil all over quick hitch and rear of 8120. Thought it was a hyd hose - but not. It appears to be running out from the "stack" of scv outlets. The planter still raised ok on number three outlet while marker wouldn't on number two. Number one outlet is for vacuum fan motor. What sort of connection is between the scv and the tractor/transmission? Did an o-ring or something blow out in there? Any thoughts? Of course it left a little trail of hydraulic oil from the back of the farm to the buildings. Not appearing as a pressure gusher but rather a low pressure leak...

Is it possibly leaking out of the O-ring and backup ring where the marker is coupled to and draining out of the body drain?
