My Wisconsin TRA-10d is always leaking oil out the breather. I've taken the cover off and taken the "reed" out but Im not sure how the crankcase vent works? How can I keep oil from running out the engine.

Unfortunately, the piston rings are probably starting to wear down and you are getting blow-by.
This creates more pressure in the crankcase than normal and pushes oil out thru the vent.
