Have a L3130 that I was clearing wood from in woods with. Ran over a 4” branch that came up and snapped lower inlet/outlet? From plastic radiator then ripped main cable from starter. Evidently loose wire touched metal and blew 50amp breaker up near battery. Replaced radiator shroud ect. Went to start nothing at dash, traced to breaker. Replaced. When I started had excessive smoke from exhaust but only for less then minute and cleared right up but have white smoke blowing constantly from breather tube that exits under tractor. Starts right up and runs smooth but didn’t smoke before accident. Any suggestions for cause? Thanks for your help.
